Performance, nutrients digestibility and economics of production of finisher broiler fed diets containing Euphorbia heterophylla leaf meal

The high cost of feed has become a great challenge in poultry production. Good quality and cheap feed is therefore crucial for optimal growth performance of poultry chickens. In this study the effect of Euphorbia heterophylla Leaf Meal (EHLM) on the performance, carcass characteristics, nutrients digestibility and economics were evaluated. Broiler chicks numbering one hundred and eighty (180) of Ross 308 strain were fed for 4 weeks. The birds were randomly allotted to six experimental diets with three replications of 10 birds each. The diets were formulated with the inclusion of EHLMat 0, 5, 10, 15, 20 and 25% levels, for T1, T2, T3, T4, T5 and T6 which replaces soyabean meal respectively and data collected were subjected to analysis of variance in a completely randomized design. Results obtained indicated that the experimental diets significantly (P<0.05) affected the average feed intake and average daily protein intake, while the average daily weight gain, average feed conversion ratio, average daily protein efficiency ratio and average final live weight were not affected (P>0.05); mortality was not affected (P>0.05) by the diet. Carcass parameters, carcass cut and internal organs such as fasted liveweight, plucked weight, dressed weight, breast weight, thigh, drum stick, neck, shank and wings, heart, empty gizzard, lungs, spleen, pancreas, small intestine and esophagus weights showed no significant (P>0.05) difference while back, head, liver, proventriculus, kidney, abdominal fat, large intestine and caeca weight were significantly (P<0.05) different. The GIT length was affected (P<0.05) by the diet except the caeca length. The nutrient digestibility of CP and NFE did not showed significant (P>0.05) effect, but CF, EE and Ash were affected (P<0.05) by the dietary treatments. The nutrient digestibility of 5%, 10%, 15% and 25% were higher than the control diet(0%) for the five nutrients evaluated. The economics of production showed that feed cost (N/kg weight gain), total income (birds sold) and total profit (net gain) were not significantly (P>0.05) different while the feed cost (N/chicken), cost saving due to EHLM inclusion, total cost of production (N/chicken) and feed cost as percentage of total cost were significantly (P<0.05) affected by the test diets. The result showed that birds fed diet containing 15% have better economic advantage for optimum benefit. Therefore 15% EHLM replacement of soya bean is recommended for adoption for optimum growth performance, carcass yield, nutrient digestibility and economics of production in finisher broiler chicken. Le coût élevé des aliments pour animaux est devenu un grand défi dans la production avicole.Une alimentation de bonne qualité et bon marché est donc cruciale pour des performances de croissance optimales des poulets de volaille. Dans cette étude, l'effet de la farine de feuilles d'Euphorbia heterophylla (EHLM) sur la performance, les caractéristiques de la carcasse, la digestibilité des nutriments et l'économie ont été évalués. Des poussins de chair au nombre de cent quatre-vingts (180) de souche Ross 308 ont été nourris pendant 4 semaines. Les oiseaux ont été répartis au hasard dans six régimes expérimentaux avec trois répétitions de 10 oiseaux chacune. Les régimes ont été formulés avec l'inclusion d'EHLM à 0, 5, 10, 15, 20 et 25%, pour T1, T2, T3, T4, T5 et T6 qui remplace respectivement le tourteau de soja et les données collectées ont été soumises à une analyse de variance. dans une conception complètement aléatoire. Les résultats obtenus ont indiqué que les régimes expérimentaux affectaient significativement (P<0,05) la consommation alimentaire moyenne et la consommation quotidienne moyenne de protéines, tandis que le gain de poids quotidien moyen, le rapport de conversion alimentaire moyen, le rapport d'efficacité protéique moye quotidien et le poids vif final moyen n'étaient pas affectés ( P>0,05) ; la mortalité n'a pas été affectée (P>0,05) par le régime alimentaire. Les paramètres de la carcasse, la coupe de la carcasse et les organes internes tels que le poids vif à jeun, le poids plumé, le poids paré, le poids de la poitrine, le poids de la cuisse, de la baguette, du cou, du jarret et des ailes, le poids du cœur, du gésier vide, des poumons, de la rate, du pancréas, de l'intestin grêle et de l'œsophage ont été montrés aucune différence significative (P> 0,05) alors que le poids du dos, de la tête, du foie, du proventricule, des reins, de la graisse abdominale, du gros intestin et des caeca étaient significativement différents (P< 0,05). La longueur GIT a été affectée (P < 0,05) par le régime, à l'exception de la longueur des caeca. La digestibilité des nutriments du CP et du NFE n'a pas montré d'effet significatif (P>0,05), mais CF, EE et Ash ont été affectés (P<0,05) par les traitements diététiques. La digestibilité des nutriments de 5 %, 10 %, 15 % et 25 % était supérieure à celle du régime témoin (0 %) pour les cinq nutriments évalués. L'économie de la production a montré que le coût de l'alimentation (N/kg de gain de poids), le revenu total (oiseaux vendus) et le bénéfice total (gain net) n'étaient pas significativement différents (P>0,05) alors que le coût de l'alimentation (N/poulet), la réduction des coûts en raison de l'inclusion de l'EHLM, le coût total de production (N/poulet) et le coût des aliments en pourcentage du coût total ont été significativement (P<0,05) affectés par les régimes d'essai. Le résultat a montré que les oiseaux nourris avec un régime contenant 15 % ont un meilleur avantage économique pour un bénéfice optimal. Par conséquent, il est recommandé d'adopter un remplacement EHLM de 15 % du soja pour des performances de croissance optimales, un rendement en carcasse, une digestibilité des éléments nutritifs et des économies de production dans le poulet de chair de finition.

A total of 144, one-day-old Arbor Acre chicks were used to investigate the effect of feeding diets containing cowpea milling waste and plantain peel meal mixture (CMWPPM) on the growth performance, nutrients digestibility and economy of feed conversion of broiler chickens. The birds were randomly allotted to four dietary treatments in a completely randomized design model, and consisted of 0, 10, 20 and 30 % dietary inclusion levels of CMWPPM. Each treatment was replicated three times with 12 chicks per replicate, making a total of 36 chicks per treatment. The experiment lasted for seven weeks. Nutrients digestibility studies were carried out at the 3rd and 7th week of the experiment using speciallydesigned metabolism cages. Results showed that at the starter phase, birds on CMWPPM 0% had significantly (P<0.05) higher feed intake, while birds on CMMPPM 20 % had significantly (P<0.05) lower feed intake than birds on the other treatments. The cost of feed and total cost of feed intake were significantly (P<0.05) higher for CMWPPM 30 % and significantly lower for CMWPPM 20 % than for the other treatments; while feed cost per kg weight gain had no significant difference across the treatments. At the finisher phase, there were no significant differences in all the growth performance parameters measured across the treatment groups. However, total cost of feed intake was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 %. The feed cost per kg weight gain was significantly (P<0.05) higher for CMWPPM 10 % and significantly (P<0.05) lower for CMWPPM 20 % and 30 % diets. Results of nutrients digestibility at the starter phase show that though dry matter, crude protein, crude fibre and nitrogen free extract digestibility were significantly (P<0.05) different across the treatments, there were no significant (P>0.05) difference in the overall total digestible nutrient across the diets. For the finisher phase, as the level of CMWPPM increased in the diets, the CP, CF, ash, lipid, NFE and TDN decreased across the treatments Therefore, it is concluded that the inclusion level of CMWPPM in the diet of broiler chickens should not exceed 20 % for optimum economy of feed conversion at the finisher phase; whereas birds can be fed diets containing 30 % dietary inclusion level of CMWPPM with good economy of feed conversion at the starter phase. Un total de 144 poussins de 'Arbor Acre' âgés d'un jour a été utilisés pour étudier l'effet des régimes alimentaires contenant des déchets de 'cowpea' et du mélange de repas defarine d'écorce de 'plantain'. (Le 'CMWPPM') sur les performances de croissance, la digestibilité des nutriments et l'économie de la conversion alimentaire des poulets de chair. Les oiseaux ont été attribués au hasard à quatre traitements diététiques dans un modèle de conception complètement aléatoire, et consistaient en des niveaux d'inclusion alimentaire de 0, 10, 20 et 30% de 'CMWPPM'. Chaque traitement a été répété trois fois avec 12 poussins par répétition, soit un total de 36 poussins par traitement. L'expérience a duré sept semaines. Des études de digestibilité des nutriments ont été réalisées à la 3ème et 7ème semaine de l'expérience en utilisant des cages de métabolisme spécialement conçues. Les résultats ont montré qu'à la phase de démarrage, les oiseaux sous 'CMWPPM' 0% avaient une ingestion alimentaire significativement (P <0,05) plus élevée, tandis que les oiseaux sous 'CMMPPM' 20% avaient une ingestion alimentaire significativement (P <0,05) inférieure à celle des oiseaux sur les autres traitements. Le coût de l'alimentation et le coût total de la prise alimentaire étaient significativement (P <0,05) plus élevés pour CMWPPM 30% et significativement plus faibles pour CMWPPM 20% que pour les autres traitements ; tandis que le coût de l'alimentation par kg de gain de poids n'avait pas de différence significative entre les traitements. Lors de la phase de finition, il n'y avait pas de différences significatives dans tous les paramètres de performance de croissance mesurés dans les groupes de traitement. Cependant, le coût total de l'ingestion alimentaire était significativement (P <0,05) plus élevé pour CMWPPM 10% et significativement (P <0,05) inférieur pour CMWPPM 20%. Le coût de l'alimentation par kg de gain de poids était significativement (P <0,05) plus élevé pour le CMWPPM 10% et significativement (P <0,05) inférieur pour les régimes CMWPPM 20% et 30%. Les résultats de la digestibilité des nutriments à la phase de démarrage montrent que bien que la digestibilité de la matière sèche, des protéines brutes, des fibres brutes et de l'extrait sans azote soient significativement différentes (P <0,05) d'un traitement à l'autre, il n'y avait pas de différence significative (P> 0,05) dans le total de nutriments digestibles à travers les régimes. Pour la phase de finition, au fur et à mesure que le niveau de 'CMWPPM' augmentait dans les régimes alimentaires, le 'CP', les 'FC', les cendres, les lipides, l'NFE et le TDN diminuaient au fil des traitements. Par conséquent, il est conclu que le niveau d'inclusion de 'CMWPPM' dans l'alimentation des poulets de chair dépasse 20% pour une économie optimale de la conversion des aliments lors de la phase de finition ; tandis que les oiseaux peuvent être nourris avec des aliments contenant 30% de taux d'inclusion alimentaire de 'CMWPPM' avec une bonne économie de conversion alimentaire lors de la phase de démarrage.

The feeding value of different levels of camel rumen content in broiler diet was investigated using 150 Hover marshal broiler chickens from one-day to 63-days of age. The birds were randomly allotted to five /diets with two replicates of 15 birds each. The diets (starter and finisher) were formulated to contain 0, 5, 10, 15 and 20% camel rumen content in T1, T2, T3, T4 and T5 diets respectively. At nine week of the experiment three birds per replicate were selected for carcass measurement. The backs, hearts, kidneys, lungs, liver and spleen were not significantly (P > 0.05) different among the treatment groups while other parameters were significantly (P<0.05) different among the treatment groups. At week eight of the experiment three birds per replicate were selected for digestibility study. At the starter stage, the daily feed intake and daily weight gain were significantly (P<0.05) different among the treatment groups but only the feed conversion ratio was not affected (P>0.05) by the camel rumen content (CRC) in the diets. However, broiler chicks fed CRC T1 (0%), T2 (5%), T3 (10%) and T4 (15%) had better daily weight gain than those fed T5 (20%). During the finisher stage, all the growth parameters were not affected (P>0.05%) by CRC except final body weight which was affected (P<0.05) by the test material. Economic of production showed that CRC diets were not profitable in terms of cost of feed per kg weight gain during the starter stage. At finisher stage the cost of feed per kg weight gain were better in broilers chicken fed CRC based-diets. The result of the experiment showed that camel rumen content can replace maize and groundnut cake up to 15% level without deleterious effect on the roductive performance of broiler chicks.However, at finisher stage up to20%dietarymaize and groundnut cake could be replaced with CRC without adverse effect on the growth performance, carcass parameters, digestibility and economics of production.

This study was carried out to evaluate the effect of 45 minutes Boiled Mucuna Seed Meal (BMSM) on the growth performance and nutrient digestibility of broiler finisher chicks. In a four-week feeding trial, three hundred and fifteen (315),4-week old broiler chicks were randomly allocated to five experimental treatment diets in a completely randomized design (CRD). Each treatment was replicated thrice having twenty-one (21) birds per pen. Boiled Mucuna seed meal was prepared and fed in graded levels of 0.0% (control diet), 10.0%, 20.0%, 30.0%, and 40.0%BMSM. Feed and water were given to the birds ad libitum. The parameters measured and calculated include final weight, weight gain, feed intake, feed to gain ratio and feed cost per kilogram gain. Digestibility of dry matter, crude protein; crude fibre, ash, nitrogen free extract and ether extract were also determined. The data collected were subjected to analysis of variance (ANOVA). The results showed that dietary levels of inclusion of BMSM had significant (P<0.05) effect on these parameters. The final weight, the weight gain and feed intake of the birds fed 0.0%, 10.0% and 20.0%BMSM were statistically (P>0.05) similar and significantly (P<0.05) higher than those of other treatments. Cost of feed per birds and feed cost per kilogram gain were lower for all BMSB diets.Digestibility of nutrients was better for the birds fed the control,10.0 and 20.0%BMSM based diets. It was concluded that inclusion of BMSM in the diets of broiler finisher chicks up to20% has no deleterious effect on growth performance and nutrient digestibility of the birds. Cette étude a été réalisée pour évaluer l'effet de 45 minutes de farine de graines de Mucuna (le 'BMSM') bouillie sur la performance de croissance et la digestibilité des éléments nutritifs des poussins finisseurs de poulet à griller. Dans un teste d'alimentation de quatre semaines, trois cent quinze (315), poussins de poulet de griller de 4 semaines ont été aléatoirement attribués à cinq régimes expérimentaux de traitement dans une conception complètement randomisée (le 'CRD'). Chaque traitement a été reproduit trois fois avec vingt et un (21) oiseaux par enclos. Le repas bouilli de graine de Mucuna a été préparé et alimenté dans les niveaux classés de 0.0% (régime de contrôle), 10.0%, 20.0%, 30.0%, et 40.0%BMSM. L'alimentation et l'eau ont été données aux oiseaux ad libitum. Les paramètres mesurés et calculés comprennent le poids final, le gain de poids, la prise d'aliments pour animaux, le rapport alimentation/gain et le coût des aliments pour animaux par gain kilogramme. La digestibilité de la matière sèche, protéines brutes; des fibres brutes, des cendres, de l'extrait sans azote et de l'extrait d'éther ont également été déterminés. Les données recueillies ont fait l'objet d'une analyse de la variance (ANOVA). Les résultats ont montré que les niveaux diététiques d'inclusion de 'BMSM' ont eu un effet significatif (P<0.05) sur ces paramètres. Le poids final, le gain de poids et la prise d'alimentation des oiseaux nourris 0.0%, 10.0% et 20.0%BMSM étaient statistiquement (P>0.05) semblables et significativement (P<0.05) plus élevés que ceux des autres traitements. Le coût de l'alimentation animale par oiseau et le coût de l'alimentation par kilogramme étaient inférieurs pour tous les régimes BMSB. La digestibilité des éléments nutritifs était meilleure pour les oiseaux alimentés le contrôle,10.0 et 20.0% BMSM régimes à base. Il a été conclu que l'inclusion du BMSM dans l'alimentation des poussins finisseurs de poulet de gril jusqu'à 20 % n'a aucun effet délétère sur la performance de croissance et la digestibilité des oiseaux en matière d'éléments nutritifs.

The Impact

Background and Aim: Grains, such as barley (BAR) and corn (CORN), are major energy sources for small ruminants. This study aimed to assess the impact of feeding either BAR or CORN-based diets on growth performance and carcass characteristics. Materials and Methods: Awassi male lambs, average body weight of 20.4±0.49 kg, were chosen randomly. Lambs were acclimated for 10 days and assigned to one of two diets (1) BAR and (2) CORN. Feeding continued for 70 days with 60 days of data collection. Daily intake was recorded. Measurements of body weight were taken starting from day 1 then once per week throughout the study period. On day 40, six lambs were randomly chosen from each group and placed in metabolism cages to assess digestibility and N balance. Lambs were slaughtered on the last day of the study to evaluate carcass characteristics and meat quality. Results: Neutral and acid detergent fiber and ether extract intake were greater (p≤0.05) for lambs fed the BAR diets. Nitrogen loss in feces tended to be greater (p=0.09) for the CORN diet. Eye muscle depth (mm) tended to be greater (p=0.07) for the BAR diet. Nutrient digestibility, daily weight gain, carcass characteristics, and meat quality were not different (p≥0.1) between diets. Conclusion: The results herein demonstrate that feeding BAR grain improved nutrient intake efficiency and consistency and did not affect weight gain and carcass traits. BAR-based diets might be a useful alternative to CORN for feeding growing lambs.

The beneficial effects of feeding rabbits with forages have been recommended. However, limited study has been made on feeding values of locally available forages in rabbits. Therefore, an experiment was conducted to evaluate the effect of Asyastasia gangetica and Brachiaria decunbens on intake, digestibility, and growth performance of rabbits. Twelve rabbits were distributed into three diets: (i) 100% commercial pellet as control (T1), (ii) 50% pellet plus Asyastasia gangetica ad libitum (T2), and (iii) 50% pellet plus Brachiaria decumbens ad libitum (T3). Daily feed intake, nutrient digestibility, weekly body weight, and feed conversion ratio (FCR) were measured. Intakes of total dry matter (DM) (121.2-134.3 g/d) and organic matter (OM) (115.1-132.5 g/d) were similar (p>0.05) for all the groups. The crude protein (CP) intake of rabbits fed with T1 (10.1 g/d) and T3 (9.6 g/d) diets was similar (p>0.05), but lower (p<0.05) than T2 (14.1 g/d) diet. Ether extract intake of rabbits fed with T2 (2.9 g/d) and T3 (3.9 g/d) diets was similar (p>0.05), but lower (p<0.05) than T1 (5.1 g/d) diet. Neutral detergent fibre (NDF) intake was higher (p<0.05) for rabbits fed with T3 (55.8 g/d) diet followed by T2 (41.7 g/d) and T1 (31.7 g/d) diets. There were no differences (p>0.05) on the digestibilities of DM, OM, and CP among treatments. Total weight gain and daily weight gain were higher (p<0.05) for rabbits fed with T1 (568 and 11.0 g) and T2 (468 and 9.0 g) diets than T3 (155 and 3.3 g) diet, respectively. The lowest FCR was obtained with T1 (12.3) and T2 (13.9) diets, whereas the highest was obtained with T3 (30.3) diet. In conclusion, diet containing Asyastasia gangetica showed more benefits in terms of CP and NDF intakes, weight gain and FCR than the diet containing Brachiaria decumbens. A combination of concentrate and Asyastasia gangetica is recommended as a partial replacement for concentrate in rabbit production.

A total of 120 broiler chickens were randomlyallocated to four treatments in the completely randomized design. Treatment 1 was thecontrol while Treatments 2, 3, and 4 were Neem ash (NTA), Shea butter ash (SBA) and Locustbean ash (LBA), respectively. Each treatment has three replicates and ten birds per replicate.Data on growth rate, live weight, feed intake and mortality were collected while feedconversion ratio was calculated. Apparent dry matter, crude protein, crude fibre, etherextract and nitrogen free extract retention were also determined. All data collected wereanalyzed using one-way analysis of variance. Starter phase results shows that birds on SBA ash had the highest final weight (366.00 g), body weight gain (173.71 g) and feed intake (546.03 g) and were significantly higher (p<0.05) than the control. At the finisher phase, all ash treatment had higher (p<0.05) final, daily weight gain and better (p<0.05) feed conversion than the control dietary. The digestibility results indicated birds on LBA diet had the highest crude fibre and ash content. The study showed that wood ash influenced growth performance and nutrient retention of broiler chickens. Chickens on ash-based diets performed better that the control at the finisher phase.

Leaf Meal

Soya bean, a conventional plant protein source in poultry feeding has become so costly and occasionally scarce resulting in high cost of poultry feed. The replacement of soya bean is therefore necessary to improve production. This study evaluated the effects of Euphorbia heterophylla (Spurge weed) leaf meal (EHLM) on the growth performance and nutrient digestibility of One Hundred and Eighty (180) Ross 308 strain of broiler chicks. They were randomly allotted to six (6) experimental diets with three replications of ten bird each and fed for 28 days. Diets were formulated such that EHLM was included as 0, 5, 10, 15, 20 and 25% levels for T1, T2, T3, T4, T5 and T6 which replaces soya bean meal in the basal diets. Data collected were subjected to analysis of variance in a completely randomized design. Results indicated that the average daily feed intake, average daily weight gain, average daily protein intake, protein efficiency ratio and average final live weight, were significantly different (P<0.05) among treatment groups while average feed conversion ratio and mortality were not affected. Digestibility coefficient of CP, CF, EE, NFE and Ash showed significant different(P<0.05) among treatment groups. However, bird fed T2, T3 and T4 digest nutrient efficiently compared with the control than T5 and T6. It was therefore concluded that upto 15% EHLM levels could be adopted for optimum growth performance and nutrient digestibility in broiler chicks aged 0-4 weeks. Le soja, une source conventionnelle de protéines végétales dans l'alimentation de la volaille, est devenu si coûteux et parfois rare, ce qui entraîne un coût élevé de l'alimentation de la volaille. Le remplacement du soja est donc nécessaire pour améliorer la production. Cette étude a évalué les effets de la farine de feuilles (EHLM) d'Euphorbia heterophylla (euphorbe ésule) sur les performances de croissance et la digestibilité des nutriments de la souche cent quatre-vingt (180) Ross 308 de poulets de chair. Ils ont été répartis au hasard dans six (6) régimes expérimentaux avec trois répétitions de dix oiseaux chacun et nourris pendant 28 jours. Les régimes ont été formulés de telle sorte que l'EHLM a été inclus en tant que niveaux de 0, 5, 10, 15, 20 et 25 % pour T1, T2, T3, T4, T5 et T6 qui remplace le tourteau de soja dans les régimes de base. Les données recueillies ont été soumises à une analyse de variance dans un plan complètement randomisé. Les résultats ont indiqué que l'apport alimentaire quotidien moyen, le gain de poids quotidien moyen, l'apport protéique quotidien moyen, le ratio d'efficacité protéique et le poids vif final moyen étaient significativement différents (P< 0,05) entre les groupes de traitement, tandis que le taux de conversion alimentaire moyen etla mortalité n'étaient pas affectés. Le coefficient de digestibilité de CP, CF, EE, NFE et Ash a montré une différence significative (P<0,05) parmi les groupes de traitement. Cependant, les oiseaux nourris avec T2, T3 et T4 digèrent efficacement les nutriments par rapport au témoin que T5 et T6. Il a donc été conclu que jusqu'à 15 % de niveaux d'EHLM pouvaient être adoptés pour des performances de croissance optimales et une digestibilité des nutriments chez les poulets de chair âgés de 0 à 4 semaines.

Leaf Meal

To contribute solutions to the problem of animal protein shortage for human consumption in Cameroon, a study was conducted at the Teaching and Research Farm of the University of Dschang- Cameroon to evaluate the effects of inclusion levels of Tithonia diversifolia leaf meal (TDLM) on growth performance and carcass characteristics of rabbits. The leaves were chopped, boiled for 5 minutes, drained, sundried, milled and analysed for proximate composition in the Laboratory of Animal Nutrition. The leaf meal was used to formulate 4 experimental diets containing 0% (control) 15, 20 and 25% of the TDLM, corresponding to T0, T1, T2 and T3, respectively. A total of 40 (20 males and 20 females) 2-months-old rabbits, weighing 1000 ± 125g were randomly assigned to the 4 dietary treatments in a 4 x 10 replicates in a completely randomized design. The live weights of the animals were evaluated weekly for 9 weeks. Eight (8) rabbits (4 males and 4 females) per treatment were randomly selected and sacrificed for carcass evaluation. The data collected were then submitted to one-way Analysis of Variance (ANOVA). Mean differences were separated using Duncan. The results showed that incorporation of TDLM induced a decrease in daily feed consumption. The least daily feed intake was observed in treatment T3 (109.14g/d) while the highest daily weight gain (24.49g/d) and the least feed conversion ratio (4.61) were also observed in the same treatment T3. However, no significant differences were observed for these parameters (P>0.05) between the treatments although daily weight gain was higher and feed conversion ratio lower in the males as compared to the females. Carcass yield (C.Y.) was higher in the control T1 (52.39%) though comparable (P>0.05) with all the other treatments. Abdominal fat was significantly (P<0.05) lower (1.90%) in the treatment T0 but it was comparable to T3 while it was highest (2.28%) in T2. However, C.Y. was higher in males and abdominal fat was higher in females when sex was considered. The relative weight of the lungs was highest in T1 (0.55%), liver in T2 (2.25%), kidneys in T1 (0.56%) and the heart in treatment T2 (0.25%) though, there were no significant differences (P> 0.05) observed in organs weights. Although there were significant differences between organs of different sexes, no regular pattern was maintained. These all signified nutritional adequacy at all levels of inclusion of TDLM, improving growth performance at the inclusion level of 25%. T. diversifolia leaves boiled for 5 minutes, sundried and milled can therefore be used as an alternative ingredient which when included in the rations of rabbits up to 25%, still compares well with conventional ingredients in growth and carcass performance irrespective of the sex. However, the use of TDLM could significantly reduce the cost of feeding and enhance meat production as it is relatively more abundant as compared to other ingredients.

Enzyme Supplementation

This study was conducted to investigate the effect of maize and yam peels meal based diets with and without enzyme supplementation on the growth performance and nutrient digestibility of broiler chickens at finisher phase. One hundred and eighty (180), one day-old broiler chicks were fed six diets in two groups. The experiment was arranged in a 2 × 3 factorial experimental layout of two levels of enzyme (0g/100kg diet and 50g/100kg diet) and three levels of yam peels inclusion (0kg, 15kg and 30kg). Each treatment was replicated 3 times consisting of 10 chicks per replicate. The experiment lasted 4 weeks. Main effect of graded levels of yam peel meal and enzymes supplementation on growth performance of starter broiler chickens showed significant (P ? 0.05) influence on final weight, total weight, total weight grain and daily weight grain. Birds fed 0% YPM recorded higher statistical value of 2549.00g for final weight. Interaction effect of YPM and enzyme showed significant (<0.05) effect on growth performance of finisher broiler chickens. Final weight, total weight gain and daily weight gain were significantly (<0.05) influenced by interaction of YPM and enzyme. Birds fed control diet (T1 ) recorded higher significant (P<0.05) values for final weight of comparative level. Least value of 2220.00g was recorded for final weight in the birds fed 15% YPM without enzyme (T2 ). Varying levels of YPM as a partial replacement for maize had no significant (P>0.05) effect on nutrient digestibility. Higher values were recorded for birds fed 0% inclusion level of YPM across the parameter determined with the exception of ether extract and ash. Inclusion of YPM with enzyme supplementation had significant (P<0.05) interaction effects on percentage dry matter digestibility, crude protein digestibility and crude fibre digestibility. Dry matter digestibility decreased with increased level of YPM with or without enzyme. Inclusion of yam peels meal up to 30% level of replacement for maize with or without enzyme supplementation could be recommended for appreciable nutrient digestibility and improved growth performance of finisher broiler chickens.
