Sažetak
High ambient temperature is considered as the major constraint on animal production in the tropics and sub-tropics regions. Thus, the objective of this study was to evaluate the effects of dietary fenugreek seeds on lactational performance and blood biochemical, hematological and antioxidant parameters of dairy goats under stressful summer conditions. Forty-two dairy Baladi goats were randomly divided into three equal groups (14 animals in each group). The first (control) group was fed a basal diet without any additives. The second (FG1) and third (FG2) groups were fed the basal diet supplemented daily with 50 g and 100 g fenugreek seeds per animal, respectively. Compared to the control group, Baladi goats in FG1 and FG2 groups had a significantly increased daily milk yield at a rate of 8.2 and 34.2%, respectively (p<0.05). Furthermore, milk protein percentages were increased by daily supplementation with either 50 or 100 g fenugreek seeds (p<0.05), but fat percentage was only decreased in the FG2 group (p<0.01). Serum glucose (p<0.05), triglycerides (p<0.01), cholesterol (p<0.01) and triiodothyronine (p<0.01) were significantly reduced after supplementation of fenugreek seeds in the diet, either FG1 or FG2 groups. Compared to the control group, both fenugreek- supplemented groups had a significantly greater serum globulin and thryoxine level (p<0.01 and p<0.05, respectively). Additionally, both fenugreeks-supplemented groups had a significantly higher total antioxidant capacity (p<0.01) and catalase activity (p<0.01). The current results indicate that supplementation of dietary fenugreek seeds may improve the milk yield, physiological and hematological parameters, and antioxidant capacity of heat-stressed goats.
