Effect of pre-calving supplementation and yeast culture on colostrun secretion, calf health and growth (Old ID 26323)

Principal Investigator

It is estimated that one million calves die in Australia every year. Between mid-pregnancy and weaning, two-thirds of losses occur within a week of birth. Cows can take several days to achieve full lactation, leaving their calves vulnerable to dehydrate and die when environmental conditions are hot. Poor nutrition during late pregancy may cause hormonal imbalances and inadequate production of colostrum resulting in inadequate transfer of passive immunity to calves and increase calf loss. It is expected that supplemented cows will have better transfer of immunoglobulins to the mammary gland, leading to greater colustrum secretion and quality improving calf health.
