Abstract
Probiotics can play an important role to improve dairy animal’s health and its productive performance through desirable manipulation of rumen fermentation. So that probiotics supplementation to dairy animals improves milk production, milk components and energy utilization.
The present study was carried out at labs of Animal Nutrition, Animal Production Department, Faculty of Agriculture, Ain Shams University, And Sanad dairy farm near Damietta, during the period from 1 January to 30 March 2017. Fifty lactating Holstein-Friesian cows (multiparous and primiparous) were distributed between the two groups 25 cows each, and the season of lactation was concerned. This experiment was started one week after calving time and extended for three months after parturition. The animals were fed total mixed ration the diets were formulated to cover NRC requirement for dairy cattle (NRC, 2001) without or with probiotic supplementation at dose 10⁶ CFU/kg DM for control and treated group, respectively. Each group was placed in a shaded pen equipped with free stalls. the diets were offered daily adlib and the animals had free excess to clean fresh water.
