This work was conducted to compare the effects of whole soybean and cotton seeds and soybean oil on the ruminal pattern and in vitro disappearance, in fistulated Holstein calves. Two calves fitted with rumen cannula were fed a basal diet with 2.5% of ether extract (EE), which was compared with 5.0% EE, where whole soybean, whole cotton seeds or soybean oil were the source of additional EE. The addition of whole soybean and cottonseed resulted in decrease on in vitro […]
