Effect of different yeast cultures supplementation to diet on the productive performance of lactating buffaloes [electronic resource].

Includes references.

Twenty lactating buffaloes were grouped into 4 feeding treatments for 25 weeks. The treatments were (1) control, (2) control+ 10g Yea-sacc¹⁰²⁶, (3) control+ 10te feed mixture: berseem clover: rice straw (50: 30 : 20, on dry matter basis). Yea-sacc¹⁰²⁶ supplementation increased (P<0.05) nutrients digestibility, milk yield, milk protein content, C₁₆ content in milk fat, histidine, phenylalanine. serine, glycine. proline and tyrosine in milk, total protein, albumin, urea nitrogen, glucose and cholesterol in blood serum than control. Lacto-sacc supplementation increased (P<0.05) nutrients digestibility, C₁₈ content in milk fat, histidine, phenylalanine. serine, glycine. ₈ 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 increased (P<0.05) nutrients digestibility, C₁₄ and C₁₆ in milk fat and glucose in blood serum, however it decreased (P<0.01) C₁₈ content in milk fat The highest nutrients digestibility, milk yield, milk protein and blood serum protein, urea, glucose and cholesterol contents were obtained with Yeasacc1026 followed by baker's yeast then Lacto-Sacc supplementations. It could be concluded that Yea-sacc¹⁰²⁶ supplementation to rations of lactating buffaloes had beneficial effects on their productive performance and a feasible economical efficiency under the farm feeding condition in Egypt.
