Abstract
The aim of this study was studying the effect of vit. B12+Fe and Cu on the somatic cell count, total bacterial count and compounds milk of Holstein cows. In this study, 4 groups contain 10 dairy Holstein cows were selected with same parity and milk production as control, vit. B12+Fe injectable (10 mL day-1), Cu injectable (2 mL day-1) and vit. B12+Fe along with Cu treatment groups. These were injected from 1 week precalving probably to 1 week after parturition. Milk samples were collected as twice weekly from the calving time to 1 week. Total Bacterial Count (TBC), Somatic Cell Count (SCC), fat, protein, Solid Non Fat (SNF) and lactose of milk were evaluated. Results showed the increasing rate of fat and lactose in vit. B12+Fe along with Cu treatment group compared to other groups. All groups were lower than control group in protein level. On the other hand, vit. B12+Fe treatment group was high in milk production, low in SNF and so, it had high effect on reducing bacterial total count compared to other groups. Furthermore, Cu treatment group was better than other groups in SCC. It was concluded that vit. B12+Fe and Cu have beneficial effects on udder immune system and compounds milk of Holstein cows.
