Effect of Mannan Oligosaccharide ( MOS) supplementation on Broiler performance

Abstract

The study was conducted at College of Animal Production Science and Technology , Sudan University of Science and Technology. One hundred and fourty four day_old broiler chicks were used. They randomly allotted to four treatment of 36 chicks of 3 replicated to determined the effect of added Y_Mos on broiler performance .Four iso_caloric and iso_nitrogeous diets were formulated contained graded levels of Y_Mos 0% , 1% , 0.8% ,0.6% as group A,B,Cand D , respectivety. Each experimental group was fed its signed diet for 42days as experimental period .The results showed that there was no significant different(P≤0.05) in the daily feed intake g/bird/day a monge experimental groups. There was significant different(p≤0.05) in daily weihgt gain (g) a monge experimental groups .Group of B(0.06%Y_Mos)has a highly value of(3.880±8.58)followed by group D of(3.579±16.42), group C of(3.547±13.331), group A of(3.427±14.024). For liver weight (g) , gizzard weight (g) , abdominal fat weight (g) ,mortality (%) no significant deferent was observed. A highly FCR recorded by group C of (1.520±0.044) while a carcass weight value of(1.496±0.051) was observed by group B . Commonly the results showed that the addition of y_mos had No negative effect on health and mortality throughout experimental period.
