Diurnal Changes in Rumen Fermentation and Blood Properties in Holstein Steers Fed a Concentrate Mixture for Fattening and Rolled Barley

Abstract

Three rumen-fistulated Holstein steers were given a high roughage diet (R) and three kinds of high concentrate diet consisting of 10kg of a concentrate mixture for fattening

Effects of ruminal dosing of mechanical stimulating brush on digestibility and rumen fermentation status in Holstein steers fed low rice straw at different lengths

“…There is a high positive correlation between chewing time and secretion of saliva (Erdman 1988). Obara et al . (1994) reported that rumen function was maintained in good condition despite the small 6.5 ± 0.6 6.9 ± 0.4 6.1 ± 0.4 6.6 ± 0.3 NS NS NS 9…”

“…There is a high positive correlation between chewing time and secretion of saliva (Erdman 1988). Obara et al . (1994) reported that rumen function was maintained in good condition despite the small amount of long rice straw provided (only 6% of the total diet) on the high concentrate diets, and discussed that the long rice straw (approximately 60 cm length) was able to provide sufficient mechanical stimulation to the upper digestive tract to maintain the digestive functions of the ruminant such as rumen motility, salivary secretion and the eructation reflex.…”
