Interdependence of productive properties of Holstein breed cows on biomass and use of mobile milking machines

Studies have established that the highest monthly milk yield in cows of all groups was noted in the third month of lactation. In this month of lactation in cows of the III group with a live weight of 481 kg and more, the monthly milk yield was, respectively, 44 and 24 kg higher than in the peers of the I and II groups. The highest monthly milk yield of cows of groups I, II and III was, respectively, 12.33%, 12.37% and 12.53% of milk yield per lactation. Studies have confirmed that the level of payment for feed with dairy products is closely related to the level of milk production of cows. The cost of feed units for milk production in high-yielding cows is noticeably lower than in less productive peers. It was also found that the use of mobile mobile milking machines contributes to the complete milking and the manifestation of the potential of milk productivity of Holstein cows

SPONTANEOUS PROLIFERATIVE ACTIVITY OF B1LYMPHOCYTES IN RHEUMATOID ARTHRITIS, SYSTEMIC LUPUS ERYTHEMATOSUS AND NON1SPECIFIC ULCERATIVE COLITIS

Abstract. The aim of present work was to study spontaneous proliferative activity of B-lymphocytes (SP-ABL) in the patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and non-specific ulcerative colitis (NSUC). In total, 128 patients with RA, 52 patients with SLE, and 29 patients with NSUC were observed. Thirty-four patients with osteoarthrosis (OA), 27 patients with reactive arthritis (ReA), 28 patients with chronic hepatitis (CH), 19 patients with chronic colitis (ChC), and 30 healthy donors comprised the control group. Significantly higher mean levels of SPABL have been revealed in the patients with RA, SLE, and NSUC, as compared to the control group. The SPABL values proved to exceed normal limits in 90.3 % of SLE patients, 82.8 % patients with RA, in 79.3 % patients with NSUC, and in 88.9 % of RA group with liver affection. Determination of SPABL may be used for assessment of immunologic activity in autoimmune inflammatory diseases
