Research Abstract

Passive immune protection in ruminants is achieved by the ingestion and absorption of adequate amounts of colostral immunoglobulins. The objective of this study was to determine the abomasal curd formation of colostrum and the effect of abomasal curd formation on gamma globlin(IgG) absorption in the newborn calves. The results of this study showed that (1) the colostrum coagulate into the curd in the abomasum and (2) nipple feeding showed better curd formation and higher serum IgG concentration compare to stomach tube feeding. We could provide new evidence of abomasal curd formation in colostrum-fed calves and an effective method for facilitating abomasal curd formation and transfer of passive immunity in new-born calves in this study.
