The study was carried out to evaluate the growth performance and feed cost benefit of starter broiler chickens offered graded levels of earthworm meal in replacement for fishmeal. Atotal of 120, one day old Anak broiler chicks were procured from a reputable hatchery and allotted to four treatment groups of 30 birds each. Each group was further divided into three replicates of 10 birds per replicate. A total number of four diets were used in the feeding trial. Diet 1 (control) has fish meal and no earthworm meal, while in diets 2,3 and 4, the quantity of fishmeal in the control diet was replaced by 25%, 50% and 100% respectively with earthworm meal. No significant difference (P>0.05) was observed in the performance of the birds. On the average daily feed intake of birds in diets 2 and 4 had high (P>0.05) feed intake, followed by the birds in diets 3, while the birds in diet 1 had the lowest feed intake. But there was no significant difference (P>0.05) in feed conversion ratio. The feed cost benefit analysis revealed a significant difference (P<0.05) on cost of feed consumed. Feed cost per kg was reduced as the levels of earthworm meal increased. Replacement of fishmeal with earthworm meal at 25%, 50% and 100% has the potential to improve the growth performance of broiler birds. Therefore, it is recommended to commercial poultry farmers to use earthworm meals in their poultry feeding.

An experiment was conducted with three hundred unsexed day-old broiler chicks (Marshal Strain) to evaluate the effect of sorghum SK-5912 variety as replacement for pearl millet on the growth performance and economics of production of broiler chickens. Five experimental diets were formulated with sorghum SK-5912 replacing pearl millet at 0, 25, 50, 75 and 100% in the diet and tagged as diets 1 (control), 2, 3, 4 and 5 respectively, for both starter phase (23%CP) and finisher phase (20%CP). The chicks were randomly allotted to the dietary treatments with four replications each and 15 birds per replicate in a completely randomized design (CRD). Feed and water were supplied ad libitum throughout the experimental period. The results showed no significant differences in feed intake, daily weight gain and FCR among the treatment means at the starter phase, finisher phase as well as the overall phase. Based on the cost benefit analysis diet 5 (100% sorghum SK-5912) had the cheapest feed cost N /kg gain of N 343.19 while the highest was diet 1 (N 373.85). It can therefore, be concluded that sorghum SK-5912 variety can replace pearl millet up to 100% in the diets of broiler chickens without negatively affecting the growth performance and with concomitant reduction in feed cost.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Effect Of Feeding

This study determined the effect of feeding trough shapes on the growth performance, carcass characteristics and cost benefit analysis of 180 broiler chickens of two strains (90 birds each of Marshal and Hubbard strains) subjected to circular, rectangular and square-shaped 2 feeding troughs with a surface area of 900 cm each. The broiler chicks were brooded for two weeks and thereafter allotted into six treatment groups of 30 chicks each, consisting of 3 replicates of 10 chicks per replicate. Daily weight gains were recorded and at the 8th week, 3 broiler chickens that were of average weights for each replicate were used for carcass evaluation. Data were analysed using PRO GLM at 5% level of significance. Results showed that feeding trough shapes significantly (P< 0.05) influenced the final weight, feed intake and feed conversion ratio. Birds on circular feeding trough recorded the best feed conversion ratio (2.98±0.03). The feeding trough shape and strain did not significantly (P>0.05) affect the cut-up parts and organs measured. In the interaction between strain and feeding trough, the dressing percentage was significantly (P<0.05) affected, but did not follow any trend. Marshal strain on square feeding trough recorded significantly (P<0.05) lowest production cost (N539.25) while Hubbard strain on circular feeder had the highest cost of N605.46. It was concluded that, in terms of cost of production, the square and rectangular shaped feeding troughs could be adopted.

A study was carried out to determine the effect of Crina Poultry Plus®, a natural blend of essential oils and benzoic acid. on the growth performance, carcass yield and nutrient digestibility of broiler chickens. Six treatment diets were formulated by the addition of Crina Poultry Plus (CPP®) at 0, 0.2, 0.3, 0.4, 0.5 and 0.6g/kg of feed. Two hundred and forty day-old chicks were allocated to the six dietary treatments with each treatment having four replicates. Each replicate had 10 broilers. The parameters measured were live weight, live weight gain, feed intake, feed conversion, protein efficiency ratio, carcass and organ    characteristics, nutrient utilization and feed cost benefit. Results of growth performance showed that there were no significant differences (P>0.05) across the treatment groups, but birds fed diets supplemented with CPP® had significantly heavier body weight (BW), higher average daily weigh gain live weight gain and similar feed conversion ratio when compared with the control group. The dressing percentage, thigh, drum stick, breast cut and back cut were not significantly (P>0.05) different across the treatment groups but those fed diet supplemented with CPP® had higher values when compared with the control diet. The supplementation of CPP® improved nutrient digestibility in broiler chickens. Birds fed diet containing 0.6g of CPP® had numerically lower cost per kg of weight gained compared to other treatment groups. It can be concluded that the addition of 0.6 g CPP® in broiler diets improved performance, carcass, organ characteristics and nutrient utilization of broilers.

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.

Abstract. In the present study, possible effects of peripheral administration of ghrelin antagonist [D-Lys3]-GHRP-6 on chicken performance, thyroid hormones level and serum biochemical parameters were investigated. Broiler chicks divided into five experimental groups were reared up to day 42. On day 21, a treatment was assigned to the five groups: group 1 (control), chickens without any administration of peptide or solution; group 2 (G50), chickens with intraperitoneal (IP) injection of 50 ng per 100 g body weight (BW) of D-Lys3 peptide on day 21; group 3 (G100), chickens with IP injection of 100 ng per 100 g BW of D-Lys3 peptide on day 21; group 4 (G150), chickens with IP injection of 150 ng per 100 g BW of D-Lys3 peptide on day 21; and group 5 (G200), chickens with IP injection of 200 ng per 100 g BW of D-Lys3 peptide on day 21. On days 21 (post-injection) and 42 (post-rearing), blood samples were obtained from the animals for laboratory analyses. Experimental groups administered the GHS-R antagonist showed less feed intake – i.e., administration of greater doses led to less feed intake (P < 0.01). Daily weight gains within groups G150 and G200 decreased (P < 0.01) in comparison with the control. The feed conversion ratio (FCR) did not differ among the groups. There was a significant difference between control and experimental groups for glucose, total cholesterol and phosphorus levels (P < 0.01) in post-injection samples. In post-injection and post-rearing blood samples, the thyroid hormone (T3 and T4) in 6 h increased in treated groups in comparison with the control (P < 0.01). The infusion of ghrelin antagonist [D-Lys3]-GHRP-6 reduces feed intake and body weight. With regard to increase in T4 level, it can be inferred that [D-Lys3]-GHRP-6 may increase metabolic rate, lipolysis and weight loss, which is similar to results obtained in mammalian species.

Energy is an important component of diets without which animals will not grow. Thus, a study was conducted to investigate the effect of low dietary energy on growth performance of broiler chicken at finisher stage. Two hundred and twenty five Zartech strain day old chicks were raised intensively for four weeks in a completely randomized design. The birds were grouped into three treatments of 75 birds and sub-divided into three replications of 25 birds. Three experimental diets of three energy levels (2,400; 2,600 and 2,800 ME Kcal/Kg designated A, B and C, respectively) with 20% crude protein were formulated and fed to the broiler chickens to assess feed intake, body weight gain, feed conversion ration and feed cost gain ration. The data were subjected to one way analysis of variance and means were separated using least significant difference. Results showed that feed intake decreased as the energy value of the feed increased. There was significant (p<0.05) difference in total feed intake between the treatments. No significant (p>0.05) difference was recorded in terms of initial live weight, final live weight, feed conversion ratio, feed conversion efficiency, feed cost and cost/gain. Feed cost showed progressive increase as the energy level of the diet increased. Lowest cost/gain ratio was reported from diet C. It was concluded that feed intake decreased as the energy value of the feed increased. It is therefore, recommended that broiler chickens should be fed with diet containing 2 800 ME Kcal/Kg as it provides the least feed conversion ratio.

One hundred and fifty (150)day-old Abor acre broiler chicks were used for this experiment toassess growth performance and carcass characteristics of broilers fed processed roselle (Hibiscus sabdariffa) seed meal were investigated. The birds were randomly assigned to five dietary treatments with three replicates (ten chicks per replicate)each in a completely randomized design (CRD). In the feeding trial, raw roselle seed meal (R RSM), roasted roselle seed meal (R RSM), boiled roselle seed meal (BRSM) and soaked roselle seed meal (SRSM) were incorporated as part replacement for groundnut cake at 50% level of inclusion.Proximate composition of the processed test ingredients and the results showed that there were no significant (P>0.05) differences among the treatment means. Raw roselle seed meal (RaRSM) gave the least crude protein while the highest was recorded in boiled roselle seed meal (BRSM). Birds fed diet without roselle seed meal inclusion (control diet) had the best final body weight and feed conversion ratio but not significantly (P>0.05) different from other treatments.Birds in treatments 2 and 4 (RaRSMand BRSM) had the least survival rate (96.67%)while the rest treatments had 100%. Cut-up parts showed no significant (P>0.05) differences exceptfor the wings of the bird fed roasted roselle seedmeal was significantly (P<0.05) different and higher than those fed control, raw, boiled and soaked roselle seed meal (10.87, 7.52, 9.85 and 9.46%, respectively). Results from visceral organs showed no significant (P>0.05) differencesexceptproventriculus which exhibited significant (P<0.05) differences among the treatment means. Proventriculus of bird fed roasted roselle seedmeal (R RSM)was highest (0.80%)while those fed raw roselle seedmeal (R RSM) gave the least (0.50%). This study however, revealed that using processed (roasted, boiled and soaked) roselle (Hibiscus sabdariffa) seed meal as part replacement for groundnut cake has no deleterious effects onthe broilerchickens.

Dietary Treatments

Poultry diets are largely composed of plant based materials that hold non-starch polysaccharides (NSP). The inclusion of NSP rich ingredients often reduces feed cost, but hampers a proper digestion due to anti-nutritional factors (ANF). Against this background, potency of exogenous enzymes was evaluated to upgrade dietary energy and total protein. A total of 180 broiler chickens were used in 28 days feeding trial. Six experimental diets were formulated in which maize based diet served as control (T1). Maize in the control diet was replaced by sorghum at the levels of 20% (T2), 40% (T3), 60% (T4), 80% (T5), and 100% (T6), respectively. Besides the control diet every other dietary groups were supplemented with enzyme at the rate of 50g/100kg. The broiler chicks were weighed and allotted to six dietary treatments of 30 birds each. The groups were replicated three times with 10 birds per replicate. The parameters determined for growth performance include: Final weight (g), Weight gain (g/bird), Daily weight gain (g/bird), Feed intake (g/bird), Daily feed intake (g/bird) and Feed conversion ratio (FCR). The result showed significant (p<0.05) effect on total feed intake and daily feed intake. Final weight, daily weight gain and feed conversion ratio (FCR) were not significantly (p>0.05) influenced by dietary treatments. Birds fed 60% (T4), 80% (T5) and 100% sorghum (T6) with enzyme supplementation showed higher similar statistical values 1365.00g, 1373.33g and 1373.66g, respectively for total feed intake. Haematological parameters were not significantly (p>0.05) affected by dietary treatments. Maize-sorghum based diet with enzyme supplementation had significant (p<0.05) effect on total protein, albumin and uric acid. Birds fed diets with 80% (T5) and 100% T6 sorghum levels with enzyme supplementation showed higher (p<0.05) statistical values 4.10 and 3.66 g/dl for total protein. Inclusion of sorghum up to 100% replacement level for maize with enzyme supplementation could be fed to starter broiler chicks for improved growth performance without adverse effect.

A feeding trial of six weeks was conducted to determine the effect of including rice offal supplemented with natuzyme on the performance of broilers. One hundred and seventy two 2 –week old broilers of mixed sexes were randomly allocated to four diets in a completely randomized design. The broiler chicks were allocated one of four diets containing either 0 (control), 5, 10, or 15% of rice offal. The starter diets were isonitrogenous (25% CP) but decreased in energy levels from 2,779.32 (Diet A), 2,747.73 (Diet B), 2,715.54 (Diet C) to 2,683.54kcal/kg ME (Diet D). The finisher diets were also isonitrogenous at 21% CP with each diet replicated three times. The energy levels of the finisher diet decreased from 2801.67 (diet A) to 2703.22 kcal/kg ME (diet D). The energy levels on diets B (2768.72) and C (2736.18) were higher than on diet D. All diets containing rice offal were supplemented with natuzyme at 100g/100kg feed. Overall result showed that feed intake was significantly lower (p<0.05) on the control (117.38g/bird/day) than on diets B (123.57), C (125.24) and D (123.97g/bird/day). Weight gain was significantly higher (p<0.05) on diet B (57.64g/bird) than on diets C (50.77) and D (46.88g/bird) respectively. Water intake was significantly lower (p<0.05) on the control (204.60mL/bird) than on diets B (240.44), C (231.86) and D (225.73mL/bird), respectively. Feed conversion ratio was significantly better (p<0.05) on diets A (2.36), B (2.23) and C (2.68) than on diet D (3.06) only. Feed cost/kg gain was significantly (p<0.05) better on diet A (N532.65) than on diets B (N666.75) and C (N688.92) only. Initial weight did not differ significantly across the diets but final weight was better (p<0.05) on diet B (2644.40g/bird) than on the control and other rice offal diets. Even though the control diet had lower feed intake, birds on diet B had better weight gain, feed conversion ratio, feed cost/gain and final body weight than the control and other rice offal diets and is therefore, recommended. This is because rice offal based diet on diet B has a cost saving of 8.33% over the control diet.
