Acidogenic value of feeds I. The relationship between the acidogenic value of feeds and in vitro ruminal pH changes
(Canadian Journal of Animal Science, 2006-03)
The objective of this study was to use an in vitro technique (i) to assess the acidogenic value (AV) of feed ingredients, (ii) to evaluate the relationship between the AV of feed and ruminal pH changes, and (iii) to determine ...
On the analysis of Canadian Holstein dairy cow lactation curves using standard growth functions
(Elsevier Inc., 2015-01-30)
Six classical growth functions (monomolecular, Schumacher, Gompertz, logistic, Richards, and Morgan) were fitted to individual and average (by parity) cumulative milk production curves of Canadian Holstein dairy cows. The ...
Effects of frequency of feed delivery on dairy cattle behavior
The objective of this study was to determine the effects of frequency of feed delivery on time budgets of individuallystalled dairy cows. The experiment was conducted as a 2 × 2 crossover design using 12 Holstein dairy ...
Effects of rumen acid load from feed and forage particle size on ruminal pH and dry matter intake in the lactating dairy cow
The objective of this study was to evaluate the effects of level of concentrate acidogenic value (AV) and forage particle size on ruminal pH and feed intake in lactating dairy cows. Two isoenergetic (net energy for lactation ...
