| Abstract | ||
| A trial was carried out to evaluate the effect of dried silage of rumen content (DSRC) and acidifiers on the growth performance of broiler chickens. A total of three hundred and twenty unsexed one day old broiler chicks (Cobb 500) were used. The birds were distributed randomly to eight experimental treatments (40 birds/treatment) with four replicates (10 birds/replicate) in a completely randomized design. The experimental diets for treatments were containing dried silage of rumen content at levels of 0, 5, 7.5 and 10% without or with 0.5g acidifiers/kg diets. The feeding trial lasted for six weeks. The obtained results showed that increasing dietary dried silage of rumen content up to 10% and 0.5g acidifier/kg diet increased significantly marketing weight of chicks, total weight gain, total feed intake and improved feed conversion ratio. Carcass traits and blood parameters were not affected by dietary dried silage of rumen content or acidifiers except HDL which was increased in blood of chicks fed diets containing 5% dried silage of rumen content. From the economic of view, it can be concluded that inclusion dried silage of cow rumen content up to 10% of the diets improve broiler performance and had no adversely effect on carcass traits, immunity or blood parameters. Also, adding acidifiers at a level of 0.5g/kg diet can be improving broiler performance. | ||
