In some physiological status such as rapid growth, parturition, disease and high production rate that imbalance would occur. High producing dairy animals are suspected to oxidative stress and require to antioxidant supplementation. Negative energy balance in early lactation force the nutrition specialist to apply oil and high NFC diet to exceed the requirement of high producing dairy animals such as Holstein cows and Saanen goats. In recent years, the attention to the use of herbal or organic antioxidant in animal nutrition has increased. This study was carried out to investigate the effects of feeding oxidized soybean oil (OSO) plus pomegranate seed (PS) as a natural antioxidant, on metabolism and physiology of Preparturient Saanen Goats. Materials and Methods Eighteen Saanen dairy goats with initial body weight of 47 ± 9 kg were assigned to three dietary treatments in a completely randomized design with repeated measurements for 21 days before anticipated parturition. Experimental treatments including: 1) base diet and 4% fresh soybean oil (FSO), 2) base diet and 4% oxidized soybean oil (DM basis) respectively, and 3) base diet plus 4% OSO and 8% Pomegranate seed (OSO-PS). After 2 weeks of feeding trial diets, goats were sampled for blood, rumen liquor, faeces and urine for measuring parameters of blood glucose, BHBA, lipid and nitrogen profile, rumen liquor ammonia nitrogen, urine pH and volume, faeces qualitative and quantitative variables and other responses such as nutrients digestibility. The GLM procedure of SAS software v.9.2 were used for statistical analysis. Initial body weight and metabolic variables were used as covariate in the model. Results and discussion All nutrients digestibility, Ruminal ammonia nitrogen and voluntary feed intake were decreased by OSO (p UR - https://ijasr.um.ac.ir/article_35134.html L1 - https://ijasr.um.ac.ir/article_35134_fc243ef7d9d847596007741a00f8b421.pdf ER -
