Efeito de uma mistura de aditivos fitogênicos alimentares nas propriedades físico-químicas do leite e parâmetros bioquímicos de vacas leiteiras da raça holandês
2021
This study aimed to analyze the effect of phytogenic additives based on cardol, cardanol, and ricinoleic acid on the physico-
chemical qualities and biochemical parameters of Holstein cow milk. Nineteen animals were divided into the control (GI) and treatment (GII)
groups. Prior to the beginning of the experiment, sodium monensin was removed from the feed provided to the animals. This study consisted
of two phases. In the first, animals from GI received the standard diet, without additives, while animals from GII received the standard diet
supplemented with 10 g of phytogenic additives for 60 days. At the end of the first stage, the animals remained 30 days without receiving
additives and in the second phase the groups were inverted, and the GII again received the phytogenic additive during the subsequent 60
days. Physical-chemical analyzes of milk were performed at moments 0, 15, 30, 45 and 60 days of the experiment and the blood parameters
at times 0 and 60 days of the experiment were evaluated. There was no significant difference for the treatment x time interaction in any of the
variables, but there was a trend between groups for the CCS parameter and there was a statistical difference for the protein, as well as for
the AST. In this study it is observed that the addition of phytogenic additive modulating rumen fermentation based on cardol, cardanol and
ricinoleic acid does not compromise, in general, the quality of milk, with positive results for some specific parameters such as protein content
and aminotransferase.
