Transitional Period Effects on Some Biochemical and Hormonal Parameters in Libyan Cows

Abstract

The aim of this study was to determine the changes in some biochemical and hormonal parameters in cows from late pregnancy to the early postpartum period (transition period). This study was carried out on 100 clinically healthy Libyan cows. Animals were divided into 3 groups, group 1 included 20 non-pregnant cows; group 2 contained 40 pregnant cows who were in the final stages of their pregnancies; and group 3 included 40 lactating cows in the first period of lactation. For biochemical analysis, serum samples were taken, including those of the minerals calcium, magnesium, and phosphorus, as well as glucose, AST, ALT, and cortisol. Significant differences in the values of biochemical and hormonal indicators, including calcium, magnesium, ALT, and cortisol, were seen between the pre- and post-partum periods (pregnant and lactating). There were no significant changes in phosphorus, glucose, or AST. These findings led to the conclusion that the transitional period affects some biochemical parameters and that cows should get mineral supplements such as calcium, phosphorus, and magnesium. Studies on major and minor components can be thought of as accurate health markers for cows during the transition period, and they can aid in the prevention of many diseases during this period.
