ABSTRACT The objective of the current study was to examine the effect of replacing maize with new or stored wheat on the nutrient intake, digestibility, digesta viscosity, and growth performance of growing broilers from 1-21 days of age. For this purpose, 560 one-day-old male broiler chicks were randomly divided into seven experimental treatments, each with 8 replicates of 10 birds. The control diet was a corn soybean-based diet, while six other experimental treatments replaced the corn of the control diet with either 50% or 100% of new, 1.5 year, and 2.5-year-old wheat. The results showed that the replacement of corn with new wheat at 50% and 100% in the diet of broilers significantly reduced feed intake and body weight gain, and increased FCR (p<0.05) at week 3. Similarly, in the overall period of the starter phase (1-21 days), replacement of corn with new wheat at 50% and 100% in the diet of broilers significantly reduced feed intake, nutrient digestibility, and body weight gain, and increased digesta viscosity and FCR (p<0.05). Based on the findings of the current study, it is concluded that stored wheat successfully replaces corn and new wheat in the diet of broilers. Furthermore, stored wheat has a positive impact on feed intake, performance parameter, digesta viscosity, and nutrient digestibility as compared to new wheat. 121 1 21 1-2 age purpose 56 onedayold one day old birds soybeanbased soybean based 50 100 15 5 1. year 2.5yearold 25yearold yearold 2.5 2 gain p<0.05 p005 p 0 05 (p<0.05 3 Similarly (1-2 days, , days) p<0.05. .

ABSTRACT The purpose of this study was to evaluate the effect of fat sources and emulsifier supplementation in different phases on growth performance of broilers. Treatments were; (T1) basal ration (BR) which contained soy oil (SO) and had inclusion of emulsifier for whole life, (T2) BR which contained poultry fat (PO) and had inclusion of emulsifier for whole life, (T3) BR which contained oxidized oil (OO) and had inclusion of emulsifier for whole life, (T4) BR which contained SO and had inclusion of emulsifier during starter phase (T5) BR which contained PO and had inclusion of emulsifier during the starter phase, (T6) BR which contained OO and had inclusion of emulsifier during the starter phase, (T7) BR which contained SO and had inclusion of emulsifier during the starter phase (T8) BR which contained PO and had inclusion of emulsifier during the grower phase, (T9) BR which contained OO and had inclusion of emulsifier during the grower phase, (T10) BR which contained SO and had inclusion of emulsifier during the finisher phase, (T11) BR which contained PO and had inclusion of emulsifier during the finisher phase (T12) BR which contained OO and had inclusion of emulsifier during the finisher phase. The Basal ration which contained SO and supplemented emulsifier during the grower phase and throughout life increased the body weight gain. The supplementation of emulsifier in the finisher phase and throughout life in a diet which contained SO had better feed conversion ratio. The supplementation of emulsifier in the finisher phase and throughout life in SO based diet increased the dry matter and crude fat digestibility. We recommend emulsifier supplementation in the finisher phase for the economic point of view.

ABSTRACT The present study was conducted to evaluate the effects of supplementation of garlic, ginger in the diets of broiler chickens and assessment in terms of feed intake, growth performance and economics of feeding. The results showed that groups supplemented with 0.5% garlic powder and 0.5% ginger powder has shown significant effects on body weight as compared to the control group at day 28. Groups supplemented with 0.5% garlic powder and 0.5% ginger powder show significant increase in body weight than the groups supplemented with 0.25% garlic powder and 0.25% ginger powder. Between different supplemented groups, villus length and width of duodenum and jejunum of birds served with 0.5% garlic powder and 0.5% ginger powder is significantly higher than the villus length and width of birds supplemented with 0.25% garlic and 0.25% ginger powder. Between different supplemented groups, villus length of ileum of the group supplemented with 0.5% garlic powder is significantly (p<0.05) lower than the villus length of the groups supplemented with 0.25% garlic powder and 0.25% ginger powder.
