EFFECT OF ADDING CORDYCEPS SINENSIS EXTRACT AND THE PROBIOTIC TO THE DIET ON THE DRESSING RATIO, THE RELATIVE WEIGHTS OF INTERNAL VISCERA AND THE MICROBIAL CONTENT OF BROILER CHICKENS

This study was carried out at the poultry farm of animal production Dep. College Agriculture –University Anbar during period from 28/10/2021 to 8/12/2021 (42 days), show effect adding Cordyceps sinensis (C.S.) extract and a probiotic in Dressing ratio, relative weights internal viscera Microbial content broilers. 210 chicks one day unsexed strain (Ross 308) were used with an average weight 40 g, randomly distributed into 7 treatments, each treatment containing 3 replicates (10 chicks/replicate) treatments as follows: T1: control without any addition diet, T2 T3 C.S level 300 600 mg/kg feed respectively, T4 T5 6 gm/kg T6 + feed, T7 3g/kg fodder. g / kg feed. The results showed significant superiority (P≤0.05) dressing percentage T2, T4, compared T1 T6, it did not differ T3. In abdominal fat, significantly superior rest treatments. There are no differences body for Fabricia, pancreas, gills, stomach, spleen, liver heart. total microbial content, all T7. also improvement numbers lactobacilli bacteria T5, Compared T1, T3, number Escherichia coli decreased T2. We conclude this that Sinensis above levels improved performance intestines, rate broilers negative effect.
