Вплив рослинного препарату на якість молозива, імунологічні показники крові новонароджених телят та енергію їх росту

Abstract

Studies have shown that the use of herbal feed additives «Fitopank» by Grey Ukrainian cows 30 days before calving had a positive effect not only on the body of cows-mothers and the quality of their colostrum, but also on the physiological state of the born calves and the growth energy of young animals. Adding of «Fitopank» to the cows diet helped to improve the quality of colostrum and its immunological value. It showed a probable increase of total protein by 10–14 % (P < 0.05) and immunoglobulin level by 23–25 % (P < 0.01). The titratable acidity of both the first and second milk yields was 16 % lower (P < 0.01) than in the control group. The use of this feed additive improved the immunological status of newborn calves. In their blood there was an increase of total protein content by 17 % (P < 0.05), the level of gamma globulins by 18% (p < 0.05), IgG concentrations by 14 % (p < 0.05), Ig M by 13 % and Ig A by 17 % (p<0.05), as well as the growth of T-lymphocytes by 46% and B-lymphocytes by 24 % (p < 0.01), compared with control group. Detected increased growth of the 8–12 months bulls (by 2.3%, p < 0.05) of the experimental group may indicate their tendency for better development of meat qualities. Experiment showed that the absolute live weight increase of young animals up to 18 months was higher than the control by 10.9 kg (p < 0.05). The study of the herbal supplements efficacy for the prevention and treatment of animals immunodeficiency, as well as their impact on the metabolic processes and productive qualities of farm animals will be the focus of our further research.
