Efecto de un producto aditivo Fitoterapéutico en la dinámica ovárica, variables sanguíneas y producción en vacas lecheras cruzadas en sistemas de producción tropicales

Reproductive nutrition is an area of study in the agricultural sciences that has recently been investigated by scientists around the world, to understand and optimize animal production. The use of bioactive products, as a feed additive, is a trend that aims to contribute to the improvement not only of production parameters, but also influences the general health of the animal. Within this improvement is reproduction, for which the objective of the present study was the evaluation of the effect of bioactive products on ovarian dynamics, metabolites, and blood biochemistry, as well as on body development, production and quality of meat. milk from a herd of cows, in a tropical environment. The study was developed at the Entre Ríos Experimental Farm, in the state of Bahía, Brazil. A total of 24 mestizo animals were used, which were divided into two groups, one control, while the second group received a bioactive additive in the daily feed. The duration of the experiment was 47 days, starting on the first day of individual supplementation of each cow. During the period of the experiment, some variables related to the dominant follicle and the corpus luteum were evaluated by means of ultrasound, likewise through the blood collection, it was analyzed by hemogram, biochemical analysis, oxidative and hormonal stress in the blood, physical examination, additionally productivity parameters. such as quantity and quality of milk, elements of body development such as body condition and weight.
