Abstract

|
Colostrum provide a complete diet for the newborn calves. In ruminants, colostrum is also the sole source of initial acquired immunity for the offspring. Colostrum, therefore, plays an important role in ruminants host defense. Bovine colostrum imparts passive immunity to newborn calves during the first 24h of life and generally has been fed for the first 3 days after birth. Colostrum can be preserved conveniently for future use by brief refrigeration, freezing, or storage at ambient temperatures (fermentation or chemical treatment). Colostrum management were surveyed via data collection from 67 dairy farms in Gyeonggi and Chungnam provinces. After parturition for five days the total amount of produced colostrum was 80.4 kg on average, and the average amount of lactation fed to a calf was 20.9kg. According to the survey results, identified treatment methods for surplus colostrum are as follows; disposal 17.9%, other calf feeding 37.3%, storage 22.4%, other livestock feeding 20.9% and other treatment 1.5%. For improvement in the quality of colostrum, there must be controlled usage of medicines(such as antibiotics) before and after parturition, proper choices of milk-drying agents, and increased milking yields during the early stage of the milking period.
