High grain content maize silage in fattening diets of young male cattle

Live-weight gain, apparent digestibility, and economic benefits of yaks fed different diets during winter on the Tibetan plateau

“…This finding is consistent with earlier findings that higher levels of intake of a particular roughage were associated with reduced digestibility (Dong et al, , 2003bLong et al, 2004) or that high feeding levels led to low digestibility by ruminants because of the more rapid passage of digesta from the rumen (Ørskov and Ryle, 1990;Ørskov, 1992;Han et al, 1992;Hao et al, 2000;Long et al, 2004) in yaks. These yak findings also reflect results in cattle and water buffalo (Levy et al, 1986;Jewell and Campling, 1986;Rule et al, 1986;Huhtanen, 1988;Elizalde et al, 1996;Hussain and Cheeke, 1996;Mulligan et al, 2002;Shane Gadberry et al, 2005), and indicate a reduction in the time available for rumen fermentation and intestinal digestion (Han et al, 1997b;Liu et al, 1997;Xue and Han, 1997). As the experiment progressed, however, new rumen microorganisms adapted gradually to high-CP and -ME diets; thus, apparent digestibility continually increased during the study.…”
