PERFORMANCE, QUALITATIVE AND QUANTITATIVE COMPOSITION OF MICROFLORA IN RUMEN
Abstract
Nutritionally balanced feeding during the dry period fully ensures the fetus growth, contributes to accumulation of nutrients in the body of animals. This paper presents the results of studies on development of a diet structure for dry cows in winter stall period. The scientific and economic experiment was carried out with highly productive animals of Belarusian black-and-white breed with body weight of 600-650 kg, housed at the state enterprise ZhodinoAgroPlemElita of Smolevichi district, Minsk region. It has been determined that the average daily weight gain of calves born from cows in the experimental group in the first month of life was 690 g, which is 4.5% higher compared to calves born from cows in the control group. Extra profit for 60 days of experiment for animals of the experimental group made 67.20 rubles.
