الملخص EN

This Experiment was carried out at Kirkuk University/ college of agriculture /department of animal resource.

From six week during the period from15/4/2013 to 15/6/2013.

The aim of this Experiment was determine effect supplement of Saccharomyces cerevisiae in water (S.C.) on broiler Ross Productive Parameters.

Thirteen Broiler ROSS 308 one day old were randomly assigned in seven day old into Four treatment groups with percentage of S.C (T0= 0, T1= 0.1, T2=0.2 andT3= 0.3 gm.

/ 100 m1 water) respectively with 75 replicates per each treatment.

The animal were fed ad labium on rations contain same crude protein (20.04%) and metabolizable energy (2989 Kcal/kg.

feed).

Feed consumption, body weight gain, feed efficiency and mortality rate were recoded weekly, At the end of fattening period 18 birds from each group were slaughtered and some carcass traits as, Carcass weight, Percentage of carcass parts Dressing percentages, weight of back, Heart and liver weight, Abdominal fat, Abdominal giblets and intestinal length a were studied.

The results indicated that percentage of Saccharomyces cerevisiae (S.C.) has significantly (p≤0.05) effect almost all production Performance.
