Summary: | ABSTRACT The aim of the study was to determine the effect of Saccharomyces cerevisiae, multienzyme composition supplementation on milk yield, quality, blood biochemical parameters of Lithuanian-Black-and-White cows. For this reason 28 cows were divided into four groups (three experimental and one control) each with seven cows fed balanced ration (control group) and following experimental groups: addition of 40g supplement of live yeast with organic selenium (group A); 40g supplement of live yeast with aromatic additives (group B); and 0.2g supplement of multienzyme composition (group C) during a 90 days period. The study showed that milk yield was 2.64%, 1.75%, 1.4% higher in groups A, B, C respectively, comparing with the control group. The milk SCC in experimental groups were lower comparing to the control group. The percentage of milk fat was significantly higher in group A - 0.33%, B - 0.31% and C - 0.16% comparing with the control group. All used additives ensure positive dynamics of investigated biochemical parameters in cattle blood. The results indicated that probiotic additives and multienzyme composition supplementation to dairy cows increased cows productivity and milk fat as well. Probiotic additives supplementation decreased SCC values in milk.
RESUMO O objetivo do estudo foi determinar o efeito de Saccharomyces cerevisiae, suplementação multienzimática na produção e qualidade de leite e em parâmetros séricos bioquímicos de vacas Preto e Brancas da Lituânia. Vinte oito vacas foram dividias em quatro grupos (três experimentais e um controle) cada um com sete vacas alimentadas com ração balanceada (grupo controle) e os grupos experimentais com: adição de 40g de suplemento de fermento vivo com selênio orgânico (grupo A); 40g de fermento vivo com aditivos aromaticos (grupo B); e 0.2g de suplemento multienzimático (grupo C) durante 90 dias. O estudo demonstrou que produção de leite foi 2,65%, 1,75%, e 1.4% mais alto nos grupos A, B, C respectivamente, quando comparados ao grupo controle. A porcentagem de gordura no leite foi significativamente maior no grupo A - 0,33%, B - 0,31%, e C - 0,16% em comparação ao grupo controle. Todos os aditivos asseguraram dinâmica positiva para parâmetros bioquímicos séricos na amostra estudada. Os resultados indicaram que aditivos probióticos e de composição multienzimática em dieta de vacas leiteiras aumentou produtividade e gordura do leite. Suplementação com aditivos probióticos reduz valores de SCC em leite. |
