PRODUCTIVITY, NATURAL RESISTANCE AND ETHOLOGICAL FEATURES OF BREEDING STEERS WHEN REARED ON DIFFERENT FLOOR AREAS
The paper presents the results of studies with purpose to determine the productivity, natural resistance and ethological characteristics of breeding steers when reared on different floor areas. It has been determined that the optimal floor area for breeding steers during the period of pen housing up to 10 months of made 3.5 m2 per animal, which contributes to increase in body weight by 2.8-7.3%, average daily weight gain - by 4.1-11.3%, decrease in feed consumption, increase in natural resistance of 0.3-4.9 p.p. and a positive effect on ethological indicators.
