Abstract
The current study focused on the study of the influence of giving aqueous extract of green tea with a mixture of vitamin A and E in the early pregnancy stage. The experiment used 20 local Awassi ewes, two years old and an average weight of 45.30 ± 2 kg. It was randomly distributed among four treatments, with five ewes for each group. The sheep of the first treatment were dosed with sterile and clean water free of additives and were regarded as the managed treatment. The second treatment was dosed with an aqueous extract of green tea at a concentration of (100 ml/ Kg BW). The third treatment was dosed with an aqueous extract of green tea water was managed in a concentration of (200 ml/ Kg BW), and the fourth treatment’ ewes are dosed with a mixture of vitamin A at a dose (400 IU/ Kg BW) and vitamin E at a dose (200 IU/ Kg BW). The administration of aqueous green tea extract, particularly at 200 ml/kg, combined with vitamins A and E, significantly improved the physiological performance of Awassi ewes during early pregnancy. Notable improvements were observed in metabolic parameters such as blood glucose, total serum protein, immunoglobulin levels, liver enzymes (AST and ALT), and serum cholesterol. These results show that green tea and vitamin supplementation may positively influence biochemical traits and metabolic activities in ewes, leading to better overall health. Further research is required to explore the underlying mechanisms and long-term effects of these treatments on sheep health.
