Influence of supplementing hay to grass once or three times per day on the effectiveness of the fibre as determined by changes in ruminal pH, chewing activity and milk composition of cows

Abstract: -Pasture grass in combination with or without 6 kg supplemental hay provided either once at 18:00 h or in three equal portions per day (07:00, 13:00, 17:00 h), respectively, were tested in a 3 × 3 Latin square design in cows for its influence on the effectiveness of fibre through modifications of ruminal pH fluctuation, chewing activity and milk constituents. Six rumen cannulated cows (Brown Swiss: Holstein = 1:1, 32.9 kg milk·day -1 ) were tested in three periods consisting of 14 days of adaptation and 7 days… Show more

“…Saliva production increases as eating and ruminating times increase (Bowman et al 2003) and by adding buffering capacity to the rumen, saliva maintains favourable ruminal fermentation conditions for fibrolytic and methanogenic activity (Russell 1998;Krause et al 2002;Graf et al 2005). Thus, although increased saliva input may increase rumen outflow (Harrison et al 1975;Owens and Goetsch 1986), it is also associated with increased CH 4 emissions.…”
