补饲不同品质饲草对哺乳期犊牛营养物质消化率和生长发育的影响

Abstract

Abstract: 10 healthy Holstein calves with similar maternal body measurement, birth weight, body measurement, were selected randomly to two groups and fed corn straw(FCS) and hay (H) respectively. The nutrient digestibility and growth performance were measured. The results showed that H had lower concentrate intake (P>0.05) and higher Forage (P<0.01) and dry matter intake (P>0.05) than FCS. Compared with FCS, NDF (P<0.01), ADF (P<0.01), crude protein (CP) (P>0.05), Ash (P>0.05) of digestibility, daily gain (P>0.05), chest girth (P>0.05), chest width (P>0.05) of H were higher. It was concluded that supplementing hay would increase the dry matter intake and nutrient digestibility of sulking calves and improve the growth performance of sulking calves and make a good condition for finishing.

Key words: sulking calves; forage; digestibility of nutrient; growth
