ABSTRACT
This study was conducted to evaluate the effect of vitamins and hormones during different stages of lactation in Lohi sheep and Beetal goats. The experiments were performed on 30 ewes and 30 goats between 1.5 to 5 years age group were selected from Bahadar Nagar Farm, Okara, Pakistan. Both the sheep and goats were grouped into three different lactating stages: [lac I (n=10), lac II (n=10) and lac III (n=10)]. Blood samples were collected during all production stages and serum has been preserved at -20 0C and used to evaluate the differences in vitamin E, vitamin C, Triiodothyronine (T3), Thyroxine (T4) and Cortisol. The statistical analysis was done by two way ANOVA and Duncan Multiple Range Test (DMRT). T3 and T4 showed significantly different results during various stages of lactation in Lohi sheep and Beetal goats. However, Vitamin E, Vitamin C and Cortisol did not reveal significantly different results during lactation in both ewes and does. It could be postulated that the evaluation of vitamins and hormones during various stages of lactation were good indicators for farm maintenance and production of these animals.
