The effect of adding garlic powder in milk on performance, nutrient digestibility, diarrhea status and blood parameters in suckling Dalagh lambs

In order to investigate the effect of feeding milk enriched with garlic powder on performance, digestibility of nutrients, diarrhea status and blood parameters in suckling lambs, twenty-four newborn lambs (birth weight 3.7±0.5) were randomly placed in three treatments and eight replications. The lambs of the control group were fed with milk without garlic powder and the other groups were fed with 1.5 and 3 grams of garlic powder per day, respectively, for 45 days. The results obtained from this research showed that consumption of garlic powder in suckling lambs led to improvement in daily weight gain, final weight and starter feed consumption (P<0.05). Also, treatments caused a significant increase in digestibility of nutrients (P<0.05). The use of garlic powder in experimental lambs improved stool consistency and significantly reduced the number of lambs with diarrhea and the average days of diarrhea (P<0.05). By adding garlic powder, the concentration of glucose and high-density lipoprotein increased (P<0.05). In addition, garlic powder caused a significant decrease in the level of triglyceride, cholesterol and low density lipoprotein in plasma (P<0.05). However, different levels of garlic powder did not make a significant difference on the concentration of urea, albumin, globulin and the ratio of albumin to globulin. According to the present results, it is possible to use garlic powder up to the level of at least 1.5 grams per day as a food additive to improve the performance and health of suckling lambs.
