Abstract
Background and objective: Medicinal plants are the most important herbal additives known in the ration of ruminant animals. Beneficial effects of using medicinal plants in animal nutrition have been observed through improving feed intake, digestibility and nutrient metabolism, and using medicinal plants in animal nutrition is an easier and more sustainable alternative than artificial sources. The object of the present study is to investigate the effect of adding a mixture of medicinal plants of black seed and coriander with different ratios to the diet of Ghaljai lambs breed on performance, haematology, biochemical metabolites and liver enzymes.
Materials and methods: Twenty-one male Ghaljai lambs with an average weight of 15.55 ± 0.89 kg (90±8 days) were divided into 3 groups of 7 in a completely random design and kept in individual pens(coop) for 40 days. Experimental groups included: 1- control (basal diet), 2- basal diet + 20 g of black seed powder 30% and 70% coriander, 3- basal diet + 20 g of plant powder 70% black seeds, and 30% coriander. Lambs were weighed every 10 days. At the end of the experiment, before morning feeding, blood was taken from the jugular vein of the lambs in order to determine the parameters of haematology, biochemical and liver enzyme properties.
Result:Results of the research showed that consumption of dry matter was higher (5.68 percent) in 2 treatment than in the control group (P<0.05). Daily weight gain and final weight also increased in the 2 and 3 treatments (17.82, 18.14 and 5.99, 6.78 percent) compared to the control group (P<0.05). No significant difference was observed between the control group and treatments in terms of the feed-to-product conversion factor. The number of red blood cells in treatment 3 was higher than in the control group (P<0.05), but medicinal plants did not affect the rest of the parameters related to red blood cells. Also, the concentration of platelets in treatment 2 was reported to be lower than in the control group (P<0.05), but related parameters of haemoglobin and white blood cells were not affected by medicinal plants. The blood glucose concentration of lambs was higher in experimental treatments (P<0.05). However, the mixture of medicinal plants did not affect triglyceride concentration, but the concentration of urea in the third treatment and the concentration of cholesterol and creatinine in the 2 treatment were lower than the control group (P<0.05). The concentration of protein and globulin in experimental treatments did not differ from the control group; on the contrary, albumin concentration in treatment 2 was higher than the control group (P<0.01). Unlike Alanbene aminotransferase, the activity of aspartate aminotransferase enzyme was higher in the 2 treatments and lower in the third treatment than the control group (P<0.01).
Conclusion: Results of the experiment showed that the use of the mixture of nigella and coriander plants with proportions of 30% nigella sativa and 70% coriander, and on the contrary, the mixture of 30% nigella sativa and 70% coriander improved the performance of Ghaljai lambs and increased the concentration of serum glucose in these lambs. It reduced urea and cholesterol and had no adverse effects on other blood parameters.
