A study was thus conducted to evaluate the effect of water acidification and sanitation on performance, gut microbial population and carcass characteristics of broiler chicken. A total of 144 broiler chickens aged one-week were utilized for the study up to 6 weeks of age. The birds were distributed into 4 treatment groups of three replicates of 12 chickens. Untreated drinking water was routinely used in the control group (T1). In T2 and T3, acidifier and sanitizer were used in an amount of 1ml and 5ml/20 liters of water, respectively, while in T4 a combination of acidifier and sanitizer was used in similar doses. There was a significant effect of acidification and sanitization of water on body weight gain and feed conversion ratio of broiler chicken. The combination of acidifier and sanitizer (T4) was found to be highly effective in improving chickens’ performance, followed by sanitizer alone (T3) and acidifier alone (T2), compared to the control group. There was no significant effect on various carcass characteristics of broiler chicken except for the gut pH and intestinal length. There was a significant effect on the pH value of various intestinal segments in broiler chickens using acidifier treated water (T2) compared to T1 and T3, but no statistical effect was noticed between T2and T4. A similar trend was noticed in the length of intestines of broiler chickens in various treatment groups. There was a significant reduction in Caecal Coliform Count ( in all the treatment groups that was used acidifier and sanitizer compared to the control group.S. Adilaadilsheikh5@gmail.comM. T.

Therefore, a study was conducted with the objectives to assess the effect of two chemicals namely aluminum sulfate and calcium carbonate on litter ammonia emission, performance and carcass characteristics of broiler chicken. A total of 240 day old Cobb broiler chicks were randomly distributed into four treatment groups, each having 4 replicates of 13 chicks each. In the control group no chemical was added to litter; however, in other groups litter was treated with Aluminum Sulfate (AS) @ 25g/kg; Calcium Carbonate (CC) @ 50g/kg; and combination of 25g Aluminum Sulfate and 50g Calcium Carbonate/kg (ASCC). The results revealed a significant (P0.05) difference among themselves. AS was found to be highly effective in reducing the ammonia emission levels, either by itself or in combination, with values of 9.46 ± 0.35 (AS) and 10.499 ± 0.39 (ASCC) compared to 47.7 ± 2.40 and 51.15 ± 1.85 ppm in CC and control. A significant (P0.05) differences were found with respect to various carcass characteristics among treatment groups as compared to control. In conclusion, compared to CC, AS was found to be highly effective in reducing the litter ammonia emission and improving the performance of birds.A. RashidM. T. BandayS. Adilaadilsheikh5@gmail.comA.

Day old commercial meat type broiler chicks (273) were procured from a reputed source. Cold conditioning (20C to 80C) at third and fourth day of age for 3-4 hours was provided to 78 birds. These early cold conditioned birds were kept separate until distributed into respective treatment groups (fifth and sixth). At the end of second week, the chicks were individually weighed, distributed into 7 treatment groups of 3 replicates with 13 chicks in each replicate. Cold challenge @ 20C to 80C for 8 hours was provided from third week of age to sixth week of their age for all treatment groups except first and fifth treatment groups. The broiler birds in the treatment groups T1 and T5 were reared under normal temperature conditions (250C). Treatment group first (T1) was kept as control group. Antioxidant Vitamin E 250 mg per kg of feed was supplemented to the basal diet in the third treatment group. Chromium 0.1 gram per kg of feed was supplemented to the basal diet in the fourth treatment group. Chromium 0.2 gram per kg of feed was supplemented to the basal diet in the seventh treatment group. The data on individual body weight of the experimental birds and the cumulative feed consumption and feed conversion ratio on group basis were recorded at weekly intervals. Deaths were recorded daily and all dead birds were necropsied to identify ascites syndrome. There was no significant (p< 0.05) difference in the average body weight and body weight gain among various treatment groups throughout the experiment period. The cumulative feed consumption showed significant (p< 0.05) difference among various treatment groups throughout the experiment period. Highest feed consumption (p< 0.05) was observed in broiler chickens reared under cold conditions when compared with broiler birds reared under normal temperature conditions. Among the cold challenge treatment groups (T2, T3, T4, T6 and T7), there was significant (p< 0.05) improvement in feed conversion ratio (FCR) in the treatment groups T6 (early cold conditioning birds exposed to cold stress) and T7 (supplementation of chromium 0.2 g/kg of feed to birds exposed to cold stress). Among different treatment groups in general best FCR was observed in treatment group T5 (early cold conditioning group reared under normal conditions) followed by T1 (control group reared under normal conditions). At the end of the biological trial ascites linked mortalities showed significant (p< 0.05) difference among various treatment groups. There was no mortality reported in treatment groups kept under normal temperature conditions (T1 and T5). Highest ascites related mortality (23.07%) was observed in treatment group in which cold stress was provided and no measures were taken to alleviate the effect of cold stress on broiler birds (T2). The Vitamin E supplementation in the diet of broiler birds reared under cold stress (T3) showed significant (p< 0.05) reduction in ascites related mortality (10.25%).S. QureshiH. M. KhanM. S. MirT.
