- A 10 week study w as conducted to investigate the effect of diets supplemented with protease on .he performance of 32 weeks old Isa Brow n hens housed in cages and fed low Crude Protein (CP) diets in a completely randomized design. A total of 60 Isa Brown laying birds were randomly allotted to 5 dietary treatments each having six replicates of 2 birds per replicate. The diets were formulated to contain 16% crude protein (Treatment 1) which was the control diet: T2. 15.2% CP diet (5% CP reduction): T3. I5.20% CP diet + 0.05% protease: T4. 14.4% CP diet (10% CP reduction) and T5. 14.4% CP diet 0.05% protease. Feed and water were supplied ad libitum. Results showed that feed intake, Haugh unit and hen day production were not significant (p > 0.05). Addition of enzyme to 15.2 and 14.4% CP diets improved egg weight, shell weight, shell thickness and albumen weight. Yolk weight was improved by 14.4% CP diet. In conclusion, 10% CP reduction plus protease gave optimum performance of the laying hens and could be adopted. 1 results 1
- A 56-day feeding trial to investigate the effects of stocking density, energy and protein content on performance of broiler chickens during late wet season was carried out. In a 3 x 2 x 3 factorial arrangement using completely randomized design, six diets with three energy and two crude protein levels were formulated. Three stocking densities (birds/m2) of 10, 12 and 14 were used. A total of 576 one-week old Arbor Acre broilers chickens were assigned to the respective diets and stocking density, at 32 birds per treatment. Weight gain, feed intake, feed conversion ratio, survival rate, carcass yield, live weight/m2 and feed cost / live weight were assessed. Data were analyzed, using descriptive statistics and ANOVA α0.05. Energy x crude protein x stocking density interaction affects the feed intake (p<0.05) and the highest value was obtained using diet with low energy and crude protein levels. Treatment did not affect (p>0.05) survival rate, however, stocking density at 12 birds/m2 resulted in the best values (p<0.05) of weight gain (2230.71g) and feed conversion ratio (2.10) and the use of diets with lower crude protein and energy increased (p<0.05) the weight gain (2312.42g). The carcass yield was affected (p<0.05) by the interaction of energy x crude protein x stocking density, (p<0.05) with the lowest value (67.33%) found with birds raised on stocking density, 10 birds/m2 and diets with low crude protein and recommended energy. The lowest feed cost/live weight (p<0.05) was observed with stocking density at 12 birds/m2. Broiler chickens may be economically raised at stocking density 12 birds/m2 and on diet containing 2933kcal/kg ME with 21.92% crude protein for starter phase and 3095 kcal/kg ME and 19.14% crude protein for finishers during late wet season in Nigeria. 1 results 1
- A study was carried out to determine the influence of fossil shell (diatomaceous earth) supplemented diets on the performance and bone composition of broiler chickens. A total of 120 day old broiler chicks were used for the experiment and randomly allotted to 5 treatments (Tl—0.9%, T2—1.2%, T3—1.5%, T4—1.8% and T5—0% inclusion levels respectively). Fossil shell inclusion had no significant influence on feed intake and feed conversion ratio, but had significant impact on weight gain. At the finisher phase no significant differences (p > 0.05) were observed for weight gain, feed intake and feed: gain ratio. Bone analysis showed that calcium content was not affected but fossil shell had significant influence on phosphorus content of the analyzed bones. 1 results 1
- A study was conducted for 8 weeks to determine the effect of administering varying levels of aqueous Tetrapleura tetraptera (African porridge fruit) on performance and gut morphology of broilers. A total of 150 day old broiler chicks (Abor acre) were randomly selected and allotted to 5 treatments and C replicates per treatment. The experimental ingredient was extracted and served to the birds in the 5 different treatments as follows; Control (water with no additive), Positive control (antibiotics), 3, 6 and 9mis respectively. Total weight gain, feed intake and feed conversion efficiency were not (P>0.05) significantly different across the varying-levels of Tetrapleura tetraptera administered. There were also no differences in feed conversion ratio of birds administered with Tetrapleura tetraptera compared with those on antibiotics. Broiler's gut parameters measured indicated that there were no significant differences (P>0.05) across the varying levels of the Tetrapleura tetraptera extract administered on the broilers. The study demonstrated that administration of Tetrapleura tetraptera extract in water for broilers compared favorably with birds on antibiotics though no significant differences were recorded. 1 results 1
- A study was conducted to evaluate the effect of Jatropha curcas leaf extract on the performance and carcass characteristics of broiler chickens. One hundred and fifty day old Arbor Acre broiler chicks were used. They were divided into five treatments and each treatment was replicated five times. Treatment one, (Negative control, no antibiotics), Treatment two (positive control, with antibiotics) while treatments three, four and five had varying inclusion levels of the Jatropha curcas leaf extract (0.25 g/100 kg, 0.50 g/100 kg and 0.75 g/100 kg of feed respectively). The birds were raised for a total number forty two days during which, they were fed ad libitum on a deep litter system of management. Weekly weight gained and feed consumed were recorded. Evisceration of carcass was done after forty two days; each part was weighed and recorded. Performance characteristics indicated no significant (P>0.05) difference in feed consumed and feed conversion ratio, but treatment 4 with 0.50 g/100 kg of Jatropha curcas extract has the best feed conversion ratio, but there were significant (P<0.05) differences in total weight gain. 1 results 1
- A study was designed to investigate the combined effects of neem and pawpaw leaves supplementation on performance and carcass characteristics of broiler chickens from 14–56 days of age. 360 one day-old unsexed Arbor acre broiler chickens were randomly allotted to the following diets T1 (0% leaf meal), T2 (0.5% NLM), T3 (2% PLM), T4 (0.5% NLM+PLM), T5 (1% NLM+PLM) and T6 (2% NLM+PLM). Results obtained from the study indicated that supplementation of NLM and PLM improved the dressing percentages, the highest values of 89.29% and 87.55% were obtained for birds on T5 and T6 respectively which were significantly different (p<0.05) when compared with the value obtained from which was 76.83%. The eviscerated weight differs significantly across the treatments, birds on T5 and T6 had significantly better (p<0.05) results of 76.93% and 75.85% respectively compared to treatments 4 and 5 which had 69.33% and 73.13% respectively. Body weight gain, feed consumed and feed conversion ratio of the broiler chickens improved in the treatments fed diets supplemented with leaf meal although and there were no significant (P>0.05) differences. 1 results 1

- Aims: The experiment was conducted to investigate the performance and carcass characteristics of meat-type chicken fed Soybean Meal (SBM) and Sesame/Soybean Meal (SSBM) supplemented with or without microbial phytase. Study Design: The experiment employed a complete randomized design; all data generated were subjected to analysis of variance, P=0.05. Place and Duration of Study: The study was carried out at the Teaching and Research Farm of the University of Ibadan, Nigeria, between October and December, 2011. Methodology: One hundred and sixty-eight unsexed two weeks old Arbor Acre strain chickens were used in a 35-day feeding trial. Two feeding regimes of soybean meal and Sesame/soybean meal based diets were formulated. Each feeding regime comprised of control diet and two levels of phytase units (300 and 600 FTU/kg) of 500 unit /g activity making a total of six dietary treatments. The birds were fed the experimental diets for a 35- and Feed Conversion Ratio (FCR). At the end of the feeding trial, three birds were slaughtered per replicate to evaluate carcass and meat characteristics. Results: The addition of phytase improved the birds’ performance, FI and FCR. Significant (P<0.05) increase was obtained for apparent retention of nitrogen (67.22%), ash (74.85%), ether extract (65.43%), crude fibre (76.22%) and Phosphorus (45.58%). Cooking loss values increased while the Water Holding Capacity (WHC) reduced with microbial phytase supplementation. Conclusion: Sesame/soybean diet supplemented with 300 FTU/Kg microbial phytase gave optimum performance and should probably be adopted as the feeding regime of choice since it also resulted in better nutrient utilization by the birds. 1 results 1

- An experiment was conducted to assess carcass characteristics and offals of broilers fed on varying forms of feeding regimes. 240, 1-day old broiler chicks-were randomly allotted to four feeding regimes each in 6 replicates of 10 birds per replicate designated as treatments as follows: ad libitum, twice a day split feeding, thrice a day split feeding and 3 hours restriction feeding. Birds were slaughtered on day 42 to determine the relative weights of the primal cuts and visceral organs. Significant differences (P<0.05) were obtained on carcass parameters' measured. Birds on ad libitum feeding had the highest bled (87.6), dressed (61.9), eviscerated (67.0) and de-feathered weights (82.5%) while the least values were obtained from birds fed thrice a day, though the values were not significantly different (P>0.05) from those of birds on twice a day split feeding regime. Birds fed ad-libitum had the highest drumstick weight (8.84%) and wing percentages (6.73%). The neck percentages were 4.47, 4.22, 3.04 and 2.84 for ad-libitum, twice a day, 3 hour restriction and thrice a day feeding respectively. Liver, abdominal and crop weights were similar (P>0.05) for ad libitum and twice feeding regime but were different (P<0.05) from thrice and restricted feeding regime. Broilers on ad libitum and twice a day feeding regimes gave the best results for carcass, primal cuts and organ weights measured. 1 results 1
- An experiment was conducted to assess the performance, welfare and digestibility of broilers fed varying forms of feeding regimes. The objective of this work research was investigate the possibility of improving growth performances, digestibility and welfare of broilers using ad libitum, split and restricted feeding. Formulated diet was given in four different forms Ad-libitum (Treatment 1) twice a day meal/split feeding (Treatment 2) thrice a day feeding (Treatment 3) 3 hours restriction feeding (Treatment 4). Experimental design was completely randomized design. 240 broilers were randomly allotted to four treatments with 6 replicates and 10 birds per replicate. Birds were weighed weekly to evaluate their performances, faeces was collected on day 42, to determine digestibility and rectal temperature was taken as a measure of bird's wellbeing. Results showed that there were no significant differences (p≥ 0.05) in performance of birds across treatments but values from birds fed Ad-libitum were higher. Rectal temperature (RT) differ at week 4, birds fed 3 hours restricted feeding had the highest RT (41.62°C) while the least RT were from birds fed Ad-libitum (41.20°C). Significant differences were obtained in digestibility and nutrient utilization of broilers with respect to feeding regimes. Crude protein (CP) digestibility was significantly higher in birds fed 3 hours restriction (81.91%) while birds fed Ad-libitum had the least (46.76%). The digestibility of crude fibre was higher in birds fed 3 hours restricted feeding regime (86.77%) the least was from birds fed thrice a day feeding regime (62.66%). A similar trend was obtained for digestibility of gross energy. Ad-libitum feeding had the highest non-significant performance values but split feeding optimized feed and nutrient utilization thereby enhancing performance and minimizing nutrient waste at the same time. 1 results 1
- An experiment was conducted to determine the comparative performance of cockerel chickens debeaked at varied length and at different ages. One hundred and ninety-five cockerel birds were purchased from a reputable hatchery, brooded and randomly allotted into 4 treatments of three replicates and 15 birds per replicate. Treatment 1 (T1) served as the control which contained 15 birds that were allotted into 3 replicates without debeaking. At the 4th week, 45 birds were debeaked at varied degrees of debeaking to form treatments 2, 3 and 4 respectively as follows: T2- ½ of upper beak and ½ of lower beak debeaked using 5 birds per replicate and 3 replicates per treatment. T3- 1/3 of upper beak and ½ of lower beak debeaked using 5 birds per replicate and 3 replicates per treatment and T4- 1/3 of upper beak and ½ of lower beak were debeaked using 5 birds per replicate and 3 replicates per treatment as it was done in all other treatments. Also, the same procedures used for all the treatments, in the 4th week as demonstrated above were repeated in the sixth, eighth and tenth week of age respectively so as to reflect the treatment effect at different ages. Data collected include: initial and final weight, daily feed intake, body weight gain and of haematological parameters. Results showed that varied degrees of debeaking examined significantly affected (p< 0.05) all the performance parameters considered: body weight gain, FCR, heterophil/lymphocyte ratio etc. It was therefore concluded that farmers should imbibe the practice of cutting half of the upper beak and half of the lower beak or one third of the upper beak and half of the lower beak (T2) preferably at the earlier stages of the birds' life as they gave better values for the performance parameters considered. 1 results 1
