Ethological Features and Hematological Indicators of Replacing Heifers When Growing at Different Floor Spaces

Abstract

As a result of the studies it was found that rearing of replacing heifers on the floor space of 1.6 m2 per head between 1 and 6 months of age, 2.5 m2 – from 6 to 12 months, and 3.0 m2 – from 12 to 18 months helps in prolonging the period of cud chewing in a standing position by 1.9 – 2.4 times, and the chewing period of food by 2.1-2.2 times. It also positively affects some blood indicators, which was expressed in a reliable increase in the lysozyme activity of blood serum by 0.2–0.3 p.p., phagocytic activity of neutrophils – by 2.7–3.0 p.p., hemoglobin content by – 3.9–4.5% and total protein – by 4.9–6.0%.
