| dc.description.abstract | The objectives of the present investigation were to study the effect of supplementation of Copper, Zinc and combination in production performance, health status and immunity in transition period of Kankrej cows. Twenty pregnant Kankrej cows at 30 days before the expected date of calving were selected and grouped into 4 homogenous groups of 5 each as control, supplemented Copper, supplemented Zinc and supplemented combination. Control group fed normal basal diet. Milk samples were collected at day 7th, 15th, 30th, 45th post partum from individual animals of each group. These milk samples were used to analysis of SCC, milk fat, milk SNF, milk lactose, milk protein and milk total solid. Blood sample was collected day of 30th, 15th at pre partum, at day of calving and day of 15th, 30th, 45th at post partum to study neutrophils percentage and total leukocyte count in blood. The SCC were observed significantly (P≤0.01) higher in day-7th and lower SCC in day 45th of lactation of all the cows. The lowest SCC in milk was found in combination group followed by Zinc, Copper and control group and they were significantly higher in control group. It indicate that micronutrient supplementation improve udder health by reducing SCC, and decreasing the incidence of Mastitis. Maximum milk fat, milk lactose and milk protein percentages were observed in combination followed by Zinc, Copper and control group. Similarly maximum milk SNF and total solid percentage were observed in Zinc 74 supplementation group followed by Copper, combination and control group respectively. Highest daily milk yield was increased after supplementation of micronutrient due to reduction of incidence of Mastitis. Highest yield was found in combination group and statistically significant differences were observed among treatments. Calves body weight was found highest in dam supplemented with combination of Cu and Zn which revealed effect of Copper and Zinc on body weight of calves when it fed to pregnant cows. The highest value of neutrophils percentage in colostrums was estimated in control as compare to other group. Copper and Zinc improve immunity of an animal because minimum increase was observed in combination supplemented cows in total leukocytes count and neutrophils percentage in blood. There was no significant difference on overall total leukocyte count of blood in Copper and Zinc supplementation. | en_US |
