REYES, J.J et al. Preliminary evaluation of the Sorbial probiotic as additive for dairy goats in grazing. Cuban J. Agric. Sci. [online]. 2015, vol.49, n.1, pp.11-15. ISSN 0864-0408.

To evaluate the Sorbial probiotic as additive for dairy goats in grazing under tropic conditions, 180 dairy goats were evaluated (90 Saanen and 90 Alpina), with 41.3 ± 0.4 kg of live weight, 23.6 days of lactation and 2.1parturition as average. The study lasted 245 days. Goats grazing (start grass and natural grass mixing) and were supplemented with 0.46 kg of concentrate animal^-1 d^-1. They were randomly distributed in 2 treatments: A.10g of probiotic in post parturition, until 100 days of lactation, and B. 0g of probiotic post parturition probiotic. The results of milk production showed that goats that consumed the probiotic, in both breeds, produced 3.9% more milk (P < 0.05) than those that did not consume it. Although, the Saanen goats produced 2.4% more milk (P < 0.05) than the Alpinas. With the probiotic usage, milk quality improved (P < 0.05) in 6.9 and 7.8% for the fat percentage and non fat solids. The costs of the milk liter, per supplement concepts, decreased (P < 0.05) in 0.012 and 0.007 Cuban pesos due to the probiotic inclusion, for Saanen and Alpine breeds, respectively. In this study conditions, the use of the probiotic during the first 100 lactation days, decreased costs per supplement concepts
