The daily control ration consisted of concentrate feed mixture (CFM): berseem and rice straw (55: 45, dry matter basis). The treatments extented to 25 weeks after parturition. Yea Sacc1026 supplementation significantly (P<0.05) increased nutrients digestibilities, milk yield, fat-corrected milk yield, milk protein content, C16 content in milk fat; histidine, phenylalanine, serine, glycine, proline, tyrosine and total non essential amino acids in milk; total protein, albumin, urea nitrogen, glucose and cholesterol in blood serum than control. Lacto Sacc supplementation significantly (P<0.05) increased nutrients digestibilities, C18 in milk fat, histidine, glycine and proline in milk, albumin and glucose in blood serum, however it decreased (P<0.05) alkaline phosphatase than control. Baker’s Yeast supplementation significantly (P<0.05) increased nutrient digestibilities; C14 and C16 in milk fat and glucose in blood serum, however it decreased 1026 (P<0.05) C18 content in milk fat. It could be concluded that Yea Sacc supplementation to the ration had a great beneficial effects on the productive performance and the economical efficiency of lactating buffaloes under the field condition in Egypt.. |
