EFFECT OF SUPLEMENTING DIET WITH DIFFERENT LEVELS OF DRIPED KEFIR MILK ON PRODUCTIVE PERFORMANCE OF LAYING HENS

Abstract

This work was carried out to study the effect of supplement diet of laying hens with dried Kefir Milk the on their productive performance. A total number of 144 laying Lohmann brown hens aged 22 weeks were, distributed randomly to four treatment with three replicates per treatment (12 hen/ replicate) The first treatments served as control group and was fed basal diet (no Kefir), The second treatments was fed the basal diet supplemented with 2 g, of dried Kefir milk/ kg  feed the third treatments was fed the basal diet supplemented with 4 g dried  Kefir milk/kg feed, while the fourth treatment was fed the basal diet  supplemented 6g dried Kefir milk/kg feed .The experiment lasted for 16 weeks till the age of 38 weeks. The results revealed significant improvement of the productive traits of the treatment received dried Kefir milk compared with the  control group (P <0.05) It may be concluded that rate of egg production (% hen day production) number weight mass of eggs. And feed efficiency during the production periods under study were significant better due to inclusion of dried  Kefir milk to layers die
