Dosing with flaxseed oil and its effect on some physiological and productive traits during the postpartum period of Awassi ewes

Abstract

This study was conducted in the animal farm, College of Agriculture, Tikrit University for the period from 01 / 09 / 2022 to 01 / 11 / 2022 to demonstrate the effect of dosing with flaxseed oil on weight gain, births, physical and chemical blood characteristics, and hormones. 17 Awassi ewes, aged 2-3 years, with an average live weight of 51.83 kg, were used. The ewes were divided randomly into three treatments. The ewes were graze daily, in addition to providing a supplemental diet at the level of 2.5% of body weight, consisting of 14.98 protein and an energy representative of 11.29 MJ/kg. dry matter. The three treatments were given flaxseed oil at 0, 0.6 and 0.8% of the dry matter of the diet, respectively. The results showed an increase in the percentage of births in the groups for the first and second treatments (116 and 166)%, respectively, compared to the control treatment (100%), while there was no significant effect between the treatments in the weights of ewes, the percentage of packed blood cells, hemoglobin, blood platelets, and total protein concentration. albumin, urea, and creatinine, and flax oil treatments excelled in the concentration of globulin, glucose, and cholesterol, while the triglycerides decreased, and the concentration of estrogen hormone in the third treatment was significantly higher (P≤0.05), while the second treatment excelled in the concentration of progesterone.
