| Abstract | This study aimed to investigate the effects of Selenium E10+ supplementation on milk yield, milk composition, and reproductive performance in postpartum dairy cows. A total of 24 crossbred Holstein Friesian cows, with an average body weight of 524±25 kg and 252±4.1 d of gestation, were used. The cows were raised under an open housing system at Samian Farm, Sukhothai province. The experiment was designed as a completely randomized design (CRD), with cows randomly assigned to receive one of three levels of Selenium E10+ supplementation (0, 30, and 50 g/h/d). All cows received the supplement daily from the 30 d of the prepartum period until 60 d postpartum. Reproductive performance and productive traits were recorded. The results showed that cows supplemented with 30 and 50 g of Selenium E10+ had significantly higher birth weights and placental weights (P<0.05). The retained placenta rate, interval to first estrus and day open were decreased (P<0.05). Feed intake before and after calving did not differ among treatments (P>0.05). There was a tendency for increased milk yield and milk fat content (P=0.07), while milk protein tended to decrease (P=0.09). Somatic cell counts significantly decreased (P<0.01) in the supplemented groups. These findings suggest that Selenium E10+ supplementation at levels of 30–50 g/h/d improves reproductive performance and tends to enhance milk production in postpartum dairy cows. |
