| Popis: | This study explored the effects of different protein and energy levels on growth performance and serum biochemical indices of ewes during early and mid-pregnancy. A total of 132 ewes were assigned to 5 groups (P1, P2 = E2, P3, E1, E3) to dietary protein levels (P1: 9.22%, P2: 10.04%, P3: 10.86%) and dietary energy levels (E1: 9.04 MJ/kg, E2: 9.53 MJ/kg, E3: 10.02 MJ/kg). Blood urea nitrogen (BUN) increased with an increase in protein levels in early pregnancy (P = .008). In the P2 group, creatinine, triglyceride, and lactate levels were lowest and total protein levels were highest in mid-pregnancy (P |
