An experiment was conducted to evaluate the efficacy of multienzyme supplement (Natuzyme?) in diets containing wheat on the broilers performance. A total of one hundred twenty day old male broiler chicks (Arbor Acres) were randomly assigned to 6 treatments with a 2 3 factorial arrangement (0, 150 and 300 gram per kilogram wheat and 0 and 0.025 gram per kilogram enzyme). Chickens were fed with starter, grower and finisher diets during 1-21, 22- 35, 36-49 days of the age, respectively. Body weight gain, feed intake, and feed conversion ratio were determined weekly and productivity efficiency index was determined at the end of experiment. Litter moisture was evaluated at the age 21 days. The results indicated that although different levels of multi-enzyme and wheat had no significant effect on body weight gain, feed intake, feed conversion ratio, productivity efficiency index and litter moisture but caused partial improvement in these parameters.

Considering the inherent attributes of tannia cocoyam (Xanthosoma sagitifolium) its appropriate utilization may enhance performance of starter broiler chicks. This study was therefore carried out to determine the dietary evaluation of starter broiler chicks fed cooked cocoyam tuber meal as energy source in place of maize. The cooked cocoyam tuber meal was used to replace maize at various levels of 25%, 50%, 75% and 100% respectively for diets 2, 3, 4 and 5 to determine the best replacement level that would give optimal performance in starter broiler chicks' diets. Result of the proximate composition of cooked cocoyam tuber meal showed that it contained 13.11% moisture, 2.60% ash, 1.85% ether extract, 3.90% crude protein, 9.45% crude fibre, 70.13% nitrogen free extract and 3004.37 Kcal/kgME. 150 day old Anak broiler chicks were used for the experiment. They were divided into 5 treatment groups of 30 broiler chicks each. Each treatment group was subdivided into 3 replicates of 10 broiler chicks each and kept in deep litter. Each starter diet was fed to a group of 30 starter broilers for 4 weeks using completely randomized design. They were given feed and water adlibitum. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and economics of production. In the starter broiler feeding trial, the starter broilers on 25% cooked cocoyam meal compared favourably with the control (P> 0.05) in terms of feed intake, body weight gain and feed conversion ratio and significantly (P > 0.05) performed between than those on 100% CCYM. The cost of production (N/Kg broiler) was however cheapest for diet 2 (25% CCYM) N395 versus control diet (N494.28). It was therefore concluded that cooked cocoyam tuber meal (Xanthosoma sagitifolium) could be used in the diets of starter broiler chicks' up to 25% without affecting the body weight gain, feed intake and feed conversion ratio as indicated in this study.

An experiment was conducted with 312 day-old male broiler chicks in grower phase(8-28d) to estimate the biological availability of four sources Zinc (Zn), Zinc sulfate(ZnSO4.H2O), two sources of Zinc oxide(ZnO FG1 and ZnO FG2) and Bioplex Zn. Zinc sulfate (ZnSO4.H2O) was used as the standard in the bioavailability assay. Chicks were allotted randomly to 13 dietary treatments with 6 birds per replicate and 4 replicates per treatment, that included an unsupplemented corn-soybean meal basal diet (25.50 mg of Zn/kg of DM), or the basal diet supplemented with 100, 150 or 200 mg/kg of DM as either ZnSO4.H2O (33 % Zn), Zinc oxide FG1(72%Zn), Zinc oxide FG2 (75%Zn) or Bioplex Zn (15% Zn). Dietary Zn level and source had no effect (P>0.05) of feed intake or body weight gain of chicks during first and second weeks of experimental periods, but feed conversion ratio in the first and second week and feed intake, body weight gain or feed conversion ratio in third week and total experimental periods were significant difference between treatments (P<0.05). The relative biological availability values using body weight gain were estimated to be 59, 99 or 45 for three levels of Zinc oxide FG1, 64, 78 or 31 for three levels of Zinc oxide FG2 and 151, 200 or 147 for three levels of Bioplex Zn, respectively. From the standpoint of bioavailability, Bioplex Zn was more available to broiler chicks than Zn from other sources and can be used by the feed industry as sources of supplemental Zn for broiler chickens.

An experiment was conduct in order to investigate the effects of feed restriction level and duration and dietary coenzyme Q10 level on growth performance, organ characteristics and plasma lipoproteins. A factorial arangment based on a completely randomized design was performed using two levels of feed restriction (10 and 20% less than the standard Ross strain 308 guidelines), two levels of restriction duration (7 and 14 days) and three levels of coenzyme Q10 (0, 20 and 40 mg/kg feed). The results of the experiment showed that restriction intensity had significant effect on feed intake in first, second and sixth weeks of age (P<0.05), body weight gain in second and sixth weeks of age (P<0.05), and feed conversion ratio in first week of age (P<0.05). Restriction duration had significant effect on feed intake in third week of age (P<0.05), and feed conversion ratio in third and sixth weeks of age (P<0.05). Coenzyme Q level had significant effect on feed intake in first and sixth weeks of age (P<0.05), body weight gain in second, fifth and sixth weeks of age (P<0.05), and feed conversion ratio in second and sixth weeks of age (P<0.05).  In conclusion, considering the positive effects of feed restriction and coenzyme Q10 on broiler yield, the simaltaneous use of feed restriction strategy and dietary coenzyme Q10 can be considered as a management program in order to improvement of broiler productivity.

One method of reducing feed cost is to restrict the feed in the early life of broilers. In this regard, Fontana et al. (1992) reported that early feed restriction programs in their experiments proportionally reduced the consumption of the starter diets by an average of 22% in restricted broilers when compared with controls. Energy restriction has also been shown to result in a reduction in metabolic energy loss leading to a reduced requirement for maintenance. If during refeeding, this low requirement is maintained and if growth resumed at a normal or above normal rate (compensatory growth), feed efficiency would be substantially improved, leading to an economical advantage. This experiment was conducted to determine the effect of severity of diet dilution (energy and protein) and duration of early feed restriction on feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) of male broiler chickens.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

Considering the inherent attributes of cocoyam tuber meal (Xanthosoma Sagitifolium), its appropriate utilization for chicken diets may enhance performance of broiler chicken. This studywas therefore carried out to determine the nutritional evaluation of fermented cocoyam tuber meal as energy source in the diets of starter broilers production. The fermented cocoyam was used to replace maize at various levels to determine the best replacement would give optimal performance in starter broilers diets. One hundred and fifty 150 day old Agrited starter broilers were used for this experiment,. The proximate composition of fermented cocoyam tuber meal (FCYM) showed that it contained 19.5% moisture, 1.30% ash, 3.56% Crude protein, 5.30% crude fibre, 1.9% ether extract and 25.48% NFE. In the starter feeding trial, the fermented cocoyam was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each starter diet was fed to a group of 30 broilers chicks for four weeks using completely randomized design. Each treatment was divided into three replicates of 10 broiler chicks each. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and cost of production. In the starter feeding trial, the starter broilers on 25% FCYM compared favorably with those on the control diet (P>0.05) in terms of feed intake, feed conversion ratio and body weight gain and hence recorded the higher body weight gain. The cost per kg feed produced was N182.50 for the control diet and the lowest was diet 5 (100% FCYM) which was N82.74. The cost of production (cost/kg feed x feed conversion ratio) of starter broilers per kg body weight gain was lowest for diet 5 (100% FCYM) (N158.86), while the costliest was those on the control diet (N383.25). The results of the trial have shown that fermentation of cocoyam tuber meal for 4 days for formulating starter broiler diets was quite an effective method of processing because fermentation reduced the anti-nutrients content. It was concluded that fermented cocoyam tuber meal could be used in the diets of starter broilers up to 25% without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

Abstract The aim of the research was to study the effects of synchronization index in the sugarcane bagasse based complete feed on feed intake, daily body weight gain and feed conversion ratio of sheep. Two permanent cannulated male local sheep was 2 years old to create formulation of three diets with different synchronization index, namely 0.37; 0.50 and 0.63 respectively. Fifteen local male sheep with body weight average of 18,32 kg (cv= 14,39%) and aged at 12 months were feed a complete feed based on bagasse with a level of synchrony index 0,37; 0,50; 0,63 were design isoprotein and isoenergy. The treatments were allotted in a randomized block design with 3 treatments and 5 groups for in-vivo test. The feed intake, daily body weight gain and feed conversion ratio of fifteen rams were determined on week 8 of experimental period. The results of the study indicated that the synchrony index did not effect on feed intake, but daily body weight and feed conversion ratio was affected (P<0.05) by the treatment of synchrony index in diet. The daily body weight gain of P2 group was highest compared with P1 and P3 groups. The feed conversion ratio of P2 group was lowest compared with P1 and P3 groups. The alteration of the study indicated that the synchronization index level of 0.50 showed the best weight gain and feed conversion. Keywords: daily body weight, feed conversion ratio, feed intake, synchrony index

This experiment was carried out to evaluate the effect of feeding Dried Tomato Pomace (DTP) with commercial ration on feed intake, body weight gain, feed conversion ratio (FCR) and economic efficiency of Rhode Island Red (RIR) grower chicks. A total of three hundred RIR grower chicks at the age of eight weeks were grouped into 20 pens of 15 chicks each, and randomly assigned to five treatments (control fed a commercial ration; 5% DTP;10% DTP; 15% DTP; 20% DTP). Birds fed on 5, 10, 15,and 20% DTP had the higher dry matter (DM) intake (72.93, 72.75, 72.98 and 73.15 g/bird/day) than the control group (72.10g/bird/day). The daily body weight gain of birds ranged from 13.3 to15.3 g/day, the highest being on birds fed on 5% DTP; The feed conversion ratio (FCR) of birds were 5.3, 4.8, 5.0, 5.3, and 5.5 for the control and for birds that consumed 5, 10, 15, and 20% DTP, respectively. The higher significant difference (p<0.05) was observed at 5%compaired with 20% DTP. The economic efficiency of the experimental diets was 1.35, 1.79, 1.80, 1.78, and 1.82 for a group fed on the control, 5, 10, 15, and 20% DTP, respectively. There was a higher significant (p<0.05) difference on a group fed on DTP and the control diet. 20% DTP brought the highest economic efficiency among the groups. Based on these results it could be concluded that dried tomato pomace could be incorporated at the level of 20% without any adverse effect on growth performance in order to increase the economic efficiency DOI: http://dx.doi.org/10.3329/ijns.v2i4.13286 International Journal of Natural Sciences (2012), 2(4) 99-103
