ABSTRACT

This study was conducted to evaluate serum biochemical constituents and antioxidant enzymes activities in non-pregnant (open), pregnant and lactating ewes exposed to nutritional climatic stress conditions. Forty pure Harri ewes at 3-6 years of age and weighing 49.6 ± 1.22 kg were synchronized for estrus and bred to pregnancy. Ewes were kept indoors in a semi open shelter and were given concentrate mix as the only daily ration during pregnancy and lactation. Pregnant ewes had higher (P<0.05) total protein than lactating that had higher albumin and lower globulin concentrations than open and pregnant ewes. Pregnant ewes had lower glucose, triglycerides and cholesterol than open and lactating ewes. Pregnant ewes had higher Na and lower K than open and lactating ewes. During last 3 months of pregnancy antioxidant enzymes glutathione peroxidase, nitric oxide and malondialdehyde rose to maximum and declined after parturition. It can be concluded that pregnant ewes often endure dramatic alteration in their metabolism due to heightened fetal development demanding more nutritional intervention to avoid pregnancy toxemia and improve productivity.
