Abstract

This experiment was conducted in one of the private fields of goat farmers in Muthanna Governorate, from 13/12/2024 to 24/1/2025 for a period of 6 weeks, to know the effect of weekly dosing with different levels of vitamin E and selenium on milk productivity and its components for local goats in Muthanna Governorate. As 12 goats (with newborns) were selected at the age of 4-5 years. The animals were divided into four treatments (each treatment had 3 animals), as the treatments were T1 (control treatment). As for the treatments T2, T3 and T4, the goats were dosed weekly with vitamin E (at a dose of 1, 1.5 and 2 mg) with selenium at a dose of 30, 45 and 60 ?g). The results indicated that all treatments of vitamin E and selenium doses were significantly superior in all studied characteristics, except for the percentage of lactose in milk, did not have a significant effect. The best level of vitamin E and selenium doses was 2 mg vitamin E and 60 ?g selenium (T4).
