Impacts of Nigella sativa Inclusion during Gestation and Lactation on Ovarian Follicle Development, as Well as the Blood and Metabolic Profiles of Ardi Goats in Subtropics

The present study aimed to alleviate the negative effects of the peripartum and postpartum periods on the timing of ovarian follicle development, milk composition, as well as blood and metabolic profiles due to Nigella sativa (N. sativa) supplementation. Twenty-seven pregnant Ardi goats were classified using a randomized complete design into three groups: a control group and two N. sativa groups (10.0 and 20.0 g N. sativa seeds per kg diet). Productive and reproductive performances, in addition to blood and metabolic profiles, were investigated and compared using Duncan&rsquo:s multiple test. N. sativa supplementation increased dry matter intake and body weight. Ruminal pH and total bacterial counts were increased versus a decreased total protozoal count due to N. sativa inclusion. Additionally, N. sativa supplementation increased the concentration of protein, lactose, solids not fat, fat, and ash in milk. Pulse rates were the lowest (p <: 0.05) in the N. sativa group and the partial pressure of oxygen was the lowest in the control group. Red and white blood cells and their related parameters (hemoglobin, hematocrit, neutrophils, and lymphocytes) showed significant increases due to N. sativa inclusion. Total protein, albumin, globulin, glucose, and minerals (calcium, phosphorus, and magnesium) values were higher (p <: 0.05) in the N. sativa group. Lower concentrations of blood urea nitrogen were found in N. sativa groups compared to control one. In conclusion, N. sativa inclusion from 4 weeks prepartum to 4 weeks postpartum of Ardi goats modified productive and reproductive performances without any adverse effects on blood and metabolic profiles.
