Produção e qualidade do leite de vacas alimentadas com Biosacch TR concentrado

Probiotics aim to improve animal performance and, therefore, their use has been increasing among production systems. To this end, this study evaluated the effect of using Biosacch TR concentrate on the production and quality of milk from dairy cows. The experiment was carried out on a private property in the city of Presidente Prudente, São Paulo (Brazil). Twenty-eight lactating cows of the Holstein and Girolanda breeds weighing an average of 520 kg were used. The production system is confined by means of paddocks, which are only for resting and supplying food in troughs, in addition to water troughs and shade, with a free area per animal of 30 square meters. The daily milk production of the animals was evaluated individually, dividing the evaluated animals (28) into two batches, with and without the supply of the product, collecting the milk produced by the animals (14 replicates) in 3 collections, 0, 12 and 24 days after the supply of the product. For milk collection and future quality analyses, 4 collections were performed, at 0, 30, 60 and 90 days, in analyses of animals from the batch with 14 animals, for the batch that already consumed the product. There was a significant increase in milk production of up to two liters per animal day for animals that consumed the product. The use of the product did not interfere with the variations in fat, protein, lactose and non-defatted extract. Regarding the somatic cell count (SCC) and total bacterial count (TBC), they decreased considerably in relation to the time of use of the product, assuming lower values from the 30rd day of use. The use of Biosacch TR concentrate increased milk production and brought benefits to the SCC and TBC values.
