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 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

A feeding trial was conducted to evaluate the performance, serum, lipid, haematology and economic indices of broiler chickens fed diets supplemented with different levels of Chestnut (Castenea sativa) phytobiotic as a replacement for antibiotic growth promoters (AGPs). A total of 300, oneday-old cobb 500 broiler chicks were allotted in a completely randomized design to five dietary treatments each replicated thrice, with 20 chicks per replicate. Chestnutphytobiotics was included at 0, 100, 125 and 150g/100 Kg diet while Oxytetracycline was included at 111g/100kg diet. Data was collected on growth performance, haematology, serum biochemical parameters, lipid profiles and economic indices. All data collected were subjected to analysis of variance and significant differences among treatment means were compared using the Duncan's Multiple Range Test of significance. At the end of the starterphase, result showed that chicks placed on 100g phytobiotics diet had significantly (P<0.05) high final weight and weight gain than other supplemented diets and control. There was significant (P<0.05) differences in the feed conversion ratio. Feed cost per kilogram gain was significantly lower in chicks fed control diet, followed by phytobiotics, however higher feed cost per kilogram gain was recorded for chicks fed diet containing Oxytetracycline. Weight gain was significantly (P < 0.05) higher on oxytetracycline based diet (1783.2g) for finisher phase however, there was an improved values for chicks placed on phytobiotics. Glucose (206.51mg/dL) was significantly higher in treatment diet that contained oxytetracycline. Haematological indices showed that values for white blood cell (91.90x103/μL) and Heterophils (20.63%) were significantly higher in diets containing oxytetracycline than other treatment groups. Values for red blood cell, monocytes, eosinophils and basophils were significantly (P<0.05) higher in broiler chickens fed diets containing 100g phytobiotics . Chestnut phytobiotics reduced the total cholesterol values from 151.13 - 96.55mg/dL when compared to other treatment groups. There were significant(P<0.05) differences in all the villi morphometry parameters measured except for crypt depth. The mean yield cost decreased as the level of phytobiotics increased. In conclusion, supplementation of Chestnut phytobiotics reduced total cholesterol and significantly improved the final weight, weight gain, feed cost per Kg gain and feed conversion ratio for both starter and finisher at 100g/100Kg. Chestnut phytobiotic is therefore a potential replacement for antibiotic growth promoters.

This study was conducted to determine the growth performance and nutrient digestibility ofbroiler chickens fed wood-ash based diet. 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.

In a completely randomized designed, two hundred and forty day-old broiler chicks were randomly assigned to four dietary treatments containing 0, 2.5, 5.0 and 7.5mg kg-1 Lcarnitine. Each of the diets contained equal amount of maize and cashew nut reject meal (CNRM). The birds were randomly divided into sixteen groups of fifteen chicks each after weight equalisation. Each diet was assigned to four groups of birds representing four replicates per experimental diet. Measurements taken during starting and finishing phase included average live weight, average weight gain, average feed intake while feed to gain ratio was calculated. Nutrient digestibility of the experimental diets was also evaluated. Results between 0-4weeks indicated that body weights ranged from 673.71g in the birds that received 2.5mgkg-1 to 700.21g in the birds that received 7.5mgkg-1 L-carnitine. Weight gain and feed intake values were significantly (P<0.05) affected by L-carnitine levels. Feed to gain ratio values were elevated when birds were fed 0 and 2.5mgkg-1 L-carnitine levels. Evaluation of nutrient utilization showed a significant (P<0.05) influence on crude protein and ether extract values. Between 5-8 weeks of rearing, feed intake increased (P<0.05) as Lcarnitine levels increased in diets while lower (P<0.05) feed to gain value was recorded at high level of dietary L carnitine. Nutrients utilization parameters were not affected (P>0.05) during finishing phase. Overall results showed that highest body weight and weight gain were obtained in the group that received 7.5mgkg-1 L-carnitine supplementation. The study showed that supplementing CNRM diets up to 7.5mgkg-1 is beneficial to growth and utilization of broiler chickens. However, this was more effective at the starter phase.

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.

Background: Copper (Cu) is an essential trace mineral for growth, production and health of poultry. Due to its poor absorption from inorganic source which is common supplemental form, large amount of Cu is excreted in the excreta. This experiment was conducted to assess the bioavailability of Cu from organic and nano sources at lower level of supplementation to reduce the excretion level without compromising the growth performance of chicken. Methods: A total of 420-day-old Giriraja chicks were randomly assigned to 7 treatment groups having 4 replicates each (15 chicks per replicate). The basal diets of both chick (0-6 weeks) and grower phases (7-10 weeks) were supplemented with 20 and 30 ppm of Cu from inorganic source as control (T1), the groups T2, T3 and T4 supplemented with 100, 75 and 50% of control from organic Cu, T5, T6 and T7 treatment diets supplemented with 75, 50 and 25% of control from Cu nanoparticles, respectively. Result: The grower phase and cumulative body weight gain was significantly (p less than 0.05) higher in T2 compared to T1, T6 and T7 groups, while the feed intake in chick phase was lower in T2, T5 and T7 groups as compared to T1, T3, T4 and T6. The chick phase feed conversion ratio was significantly (p less than 0.05) better in T2 and T5 groups compared to T1, T3, T4, T6 and T7, whereas the cumulative FCR was better in T2 and T5 compared to T6 and T7 groups, while it was not affected during grower phase. The dry matter and crude protein metabolizability were significantly (p less than 0.05) higher in T2 and T5, the organic matter and ether extract metabolizability was higher only in T5. The crude fiber and nitrogen free extract was not affected by the treatment diets. Nitrogen excretion was significantly (p less than 0.05) lower and its retention was higher in T2 and T5 treatment groups but was comparable with control. The Cu excretion through excreta was significantly (p less than 0.05) higher and its retention was lower in control as compared to all dietary treatments. Hence, it was concluded that the Cu supplementation from organic or nanoparticles form can be reduced by 50 and 75% of standard, respectively without compromising the growth performance of birds and nutrient digestibility of diets.

A 21-d investigation was conducted to ascertain the effect of 50% whole millet grain replacement for milled millet on growth performance, gastrointestinal conditions and development in broiler chickens. Eighty-four one-day-old unsexed broiler chicks were randomly allotted to two treatment groups with 7 replicates of 6 chicks per replicate. Two diets; whole millet diet (WM), consisting of 50% of the millet provided as whole grain, and the ground millet diet (GM), as the control, were formulated and fed ad-libitum throughout the study period. Performance data: feed intake, daily live weight gain and feed conversion ratio were recorded weekly, i.e. at 7, 14 and 21d, while gastrointestinal assessment: jejunal, digesta pH, relative weights of the proventriculus, gizzard, pancreas and liver, and jejunal and ileal morphometry were conducted on 21d. Similarities (p > 0.05) were observed in the growth performance, digesta pH and relative weight and length of duodenum, jejunum, ileum and caeca for chickens in both treatments. A 25.7% increase in gizzard weight was observed in chickens on WM, as well as significant (p < 0.05) increases in jejunal and ileal height and jejunal villus width were recorded on the chickens. A significant reduction in flock uniformity was observed in chickens fed the whole millet diet at 14d. It could therefore be concluded that 50% whole millet grain replacement for milled millet resulted in similar growth performance and improved gastrointestinal function and activity in 21-d post hatch chickens.

The increase in human population, particularly in the developing countries like Nigeria and the demand for animal protein intake has necessitated different approaches of solving protein shortage. A 28-day study was carried out to determine the performance of finishers fed on different hourly soaked doum palm (Hyphaene thebaica) pulp meal (DPPM) diets. Two hundred and sixteen (216) finishers (4 week-old) were randomly allotted to six dietary treatments. Each treatment consisted of 36 birds with three replicates (12 birds per replicate) in a completely randomized design (CRD). Six experimental diets were formulated and designed as follows: T1 (Control) contained 0% DPPM while T2, T3, T4, T5 and T6 contained 12.5% each of 2, 4, 6, 8 and 10 hours soaked DPPM as substitute for maize, respectively. Feeds and water were provided ad libitum for all treatment groups. The average body weight gain (40.44- 42.71 g/b/d), average feed intake (87.52-96.73 g/b/d) and feed conversion ratio (2.14-2.34) were non-significant (p>0.05) regardless of the dietary treatments. Statistical differences (p<0.05) were observed in some carcass parameters such as thigh (13.40-14.98%), neck (5.32-6.55%), shank (3.81-5.2 %), wing (9.80-11.41%), head (2.43-3.74%) and two haematological indices; white blood cell (160.67-189.53 X 103/mm3) and eosinophils (0.33-2.00%) across the treatment groups. The processed DPPM could serve as a rich energy source in broiler feeds with the raw doum palm pulp containing 2987.45 kcal/kg. Also, soaking the pulp for 2 to 10 hours before been included in broiler diet improved the nutritional content, acceptability, palatability and utilization of the feed by the broilers. Thus, up to 12.5% processed DPPM can be included in the diets of broiler chickens without adverse effect on growth performance, nutrient digestibility, carcass characteristics and haematological indices of chickens.

The effects of instant noodles waste (INW) as a replacement for maize was investigated using 144 day-old, unsexed broiler chicks of Anak strain which were randomly assigned into four dietary treatment groups of 36 birds each. Each dietary treatment group had 3 replicates of 12 broilers per replicate. These four different diets were fed, in which INW replaced maize at 0% (control), 10, 20 and 30% from day old to 8 weeks of age. The growth performance, nutrient digestibility, haematological parameters and carcass traits of the chickens were evaluated. Average final live from 1559.44 g to 1730.91g with broilers fed control diet and 30% INW diet recording the highest and least values respectively among the treatments. Broilers fed the 30 % INW had lower (P< 0.05) live weight. Broilers fed INW based diets had higher blood profile comparable to the control. The results indicated that INW can replace up to 20% of broiler starter diet and 30% replacement of maize at the finisher phase without adverse effects on growth performance of the broilers.
