Özet
Since dairy cows have greater milk production than beef cows, because of the dilution of Immunoglobulin G (IgG) colostrum of dairy cows assumed to be of poorer quality compared with beef cows. The objective of the present study was to investigate quality of colostrum and total IgG produced in a lactation by Holstein cows (n=80). The average colostrum volume at the first seven milking were measured as 5.42 L, 6.73 L, 8.55 L, 9.26 L, 8.44 L, 9 L, 10.01 L respectively. The average total colostrum produced by cows in the first 3 days period was calculated as 57.41 L. The average colostrum IgG concentration were calculated as 90.81 mg/mL, 68.67 mg/mL, 58.40 mg/mL, 37.33 mg/mL, 15.22 mg/mL, 10.7 mg/mL, 5.9 mg/mL respectively for each milking. In conclusion, enough colostrum and IgG are produced in the first 3 days in Holstein cows for calf feeding. In addition to this, there is huge opportunity that excessive amount of IgG and colostrum could be processed for other by-products.
