Abstract
ABSTRACT :
An experiment was carried out to study the effect of varying levels of garlic supplementation on the growth performance, haematology, blood biochemical parameters and immunological response in murrah buffalo calves. Eighteen murrah buffalo calves of 4-5 months age were randomly divided in to three groups of six calves each i.e. T0, T1, and T2. The T1, and T2 groups were supplemented with garlic powder at the dose rate of 250 and 300 mg per kg body weight in the concentrate feed, respectively, for a period of 90 days while T0 group served as control. All the experimental calves were fed individually with Hybrid Napier green fodder and concentrate feed (calf grower) as the basal diet. The results of the experiment revealed that significant (P<0.01) increase in overall feed intake, body weight gain, body condition score, average daily gain and feed conversion efficiency in garlic supplemented buffalo calves (T1, and T2 ) compared to control group (T0) while the difference was not significant between T1, and T2 calves. However, significant difference was not observed in the faecal consistency score among the garlic supplemented and control group buffalo calves The haemoglobin levels, red blood cells, white blood cells and packed cell volume were significantly (P<0.01) increased in T1, and T2 groups compared to T0 buffalo calves. However, no significant difference was observed in MCV, MCH and MCHC levels among the garlic supplemented and control group buffalo calves. Significant (P<0.01) increase in the lymphocyte count and a significant (P<0.01) decrease in the neutrophil count was also observed in garlic supplemented buffalo calves compared to control group. However, no significant difference was observed in the eosinophil, basophil and monocyte count among the garlic supplemented calves and control calves. The blood glucose, serum cholesterol, SGOT and creatinine levels were significantly (P<0.01) decreased and total protein, albumin, globulin and HDL cholesterol levels were significantly (P<0.01) increased in T1, and T2 groups compared to T0 buffalo calves. However, no significant difference was observed in serum calcium and phosphorus levels among the garlic supplemented calves and control calves.
Garlic supplementation did not show any significant effect on immune response against FMD vaccine in buffalo calves. Further, the total cost of feeding and the feed cost per kg weight gain was higher in garlic supplemented groups as compared with the control group.
Based on the above results, it can be concluded that garlic powder can be supplemented in the diet of buffalo calves to improve their overall growth performance, blood constituents and defense mechanism by improving the total leucocyte count and lymphocyte count and decrease the serum cholesterol which promote the overall health and well-being of the calves.
