The influence of a dietary supplementation with Saccharomyces cerevisiae (SC) during the first and the second phase of lactation on dry matter (DM) intake, organic matter digestibility, milk yield and quality and haematological profile was evaluated in buffalo cows. Lactating buffaloes (n=190), 118.7 days in milk (DIM), were randomly divided into Group C (control, n=95) and Group T (fed diet supplemented with 98 billion CFU of S. cerevisiae, n=95). Eight buffaloes for each group (Groups T1 and C1), 85.4 DIM, were used to study the in vivo digestibility and the haematological profile. No differences were found for DM intake (16.5 kg·day−1) and haematological profile. The SC supplementation increased milk yield (7.9±0.2 vs. 7.4±0.2; Pb0.01) but did not affect milk fat and protein. SC supplementation increased OM digestibility, mainly, in the first phase of lactation (b135 days), thus allowing a higher energy availability for milk yield and reduced fat mobilization.

Abstract

The influence of a dietary supplementation with Saccharomyces cerevisiae (SC) during the first and the second phase of lactation on dry matter (DM) intake, organic matter digestibility, milk yield and quality and haematological profile was evaluated in buffalo cows. Lactating buffaloes (n=190), 118.7 days in milk (DIM), were randomly divided into Group C (control, n=95) and Group T (fed diet supplemented with 98 billion CFU of S. cerevisiae, n=95). Eight buffaloes for each group (Groups T1 and C1), 85.4 DIM, were used to study the in vivo digestibility and the haematological profile. No differences were found for DM intake (16.5 kg·day−1) and haematological profile. The SC supplementation increased milk yield (7.9±0.2 vs. 7.4±0.2; Pb0.01) but did not affect milk fat and protein. SC supplementation increased OM digestibility, mainly, in the first phase of lactation (b135 days), thus allowing a higher energy availability for milk yield and reduced fat mobilization.
