The effect of adding different levels of Vitamin C, E, Aspirin and Sodium Chlorides in diet for total digestible nutrients, and some organ relative weights and carcass traits of broiler chickens during heat stress

Abstract

Abstract This Study was conducted in Poultry research Station, which belongs to Department of Livestock researches in Department of Agricultural researches in Iraqi Ministry of Agriculture (Baghdad/ Abu Gharib) for the period from June 6th 2016 to Nov 17th 2016, where 336, one day old chicken were used in this study. These chickens were brought from Al-Shukur hatch located in Abu-Gharib, with the primary weight of 39g of the Ross 308 Dynasty and it was naturalized. The chicken were randomly divided in 8 groups, and each groups contained 3 sub-groups with 14 chicken in each one. Where the first Group was Control Group, and the chicken in 2nd and 3rd groups were given Vitamin E with the amount of 250 and 500 mg/ kg in their feed respectably. As for the 4th and 5th groups, there were given Vitamin C with the amount of 250-500mg/kg in their feed respectively. As for the 6th and 7th groups, there were given Aspirin with the amount of 250-500mg/kg in their feed respectably. And for the 8th group, it was given the amount of 250 g/kg of Sodium Chloride in their feed. The continuous light method was used 24 hours a day in the hall and Gas incubators were used to maintain increase the temperature and achieve thermal effort until the end of the experiment (42 days) and the temperature of 35 C was maintained during the entire study. Results have shown the effects in the digesting elements of chicken, where and actual increase was shown in the digesting of fibers in 2nd group in comparison with 1st, 4th, 6th and 8th groups. As for abstract Ether, it was relatively increased in 2nd group in comparison with 1st, 5th and 7th group. As for the feed that didn’t contain any Nitrogen we can see that 1st group relatively increased in comparison with 2nd, 3rd and 8th groups. As for the effect of the additional which were added to the feeding elements that created energy they were relatively increased in comparison with all the other additions. As for their effect in weight on females’ chickens, it was relatively increased in 4th group where the liver sized was bigger in comparison with 1st, 2nd, 6th and 7th group. As for the weight of the chipset it was relatively increased for the 2nd group in comparison with 3rd group. As for the actual weight of spleen it was relatively increased in 8th group in comparison with 3rd group. As for the weights of Fabrica it was relatively increased in in 6th group in comparison with 3rd, 7th, 8th groups.As for the percentage of reflux without the edible parts it was relatively increased in group 7 in comparison with 1st Group. As for the percentage of reflux with the edible parts it has been relatively increased in the 7th and 8th Group in comparison with 1st Group. As for the effect in weight for male chicken, it was relatively increased in 5th and 7th group in comparison with 2nd group. As for the relative weight in glandular stomach it has been relatively increased in make chicken for the 2nd group in comparison with 3rd and 6th group. As for the effects of additions to the relative weights of chicken it was relatively increased in 7th group in the weight of the heart in comparison with 2nd, 3rd and 6th group. As for the relative weight in chipset it was relatively increased in in 4th and 5th group in comparison with 3rd group. As for the relative weight of spleen it was relatively increased in 8th group in comparison with 3rd group. As for the refinement ratio with edible portions of meat boilers it has been relatively increased in 8th group in comparison with 1st group
