Milk yield, rumen fermentation, and microbiota of Shami goats fed diets supplemented with spirulina and yeast.

ABSTRACT: Microalgae and live yeast have gained interest in improving animal performance. This study evaluated the effect of supplementation with Spirulina platensis, Saccharomyces cerevisiae, or their combination on the in vitro and in vivo rumen fermentation, rumen microbiota, and milk yield and composition of lactating Shami goats. The in vitro experiment included four diets: non-supplemented basal diet consisted of Alfalfa hay and a concentrate feed mixture (C); basal diet supplemented with 1% Saccharomyces (Y) based on dry matter; basal diet supplemented with 1% Spirulina (A); and basal diet supplemented with 1% of a mixture of Saccharomyces and Spirulina (AY). In the in vivo experiment, twenty-one lactating goats were divided into three groups (n = 7) to receive one of three diets: C, A, and A
