Effects of alfalfa silage storage structure and roasting corn on ruminal digestion and microbial CP synthesis in lactating dairy cows.
The objective of this experiment was to quantify the effects of unroasted or roasted ground-shelled corn (GSC), when fed with alfalfa ensiled in bag, bunker, or O2-limiting tower silos on ruminal digestion and microbial CP synthesis in lactating dairy cows. The roasted corn was heat-treated in a propane-fired roasting system. Alfalfa was harvested as second cutting from fields with regrowth of ...
متن کاملShort communication: Effect of subacute ruminal acidosis on in situ fiber digestion in lactating dairy cows.
Subacute ruminal acidosis (SARA) was induced by replacing 25% of the total mixed ration intake [dry matter (DM) basis] with pellets consisting of 50% wheat and 50% barley. This reduced dietary forage content (DM basis) from 39.7 to 29.8% and increased the dietary concentrate content from 60.3 to 70.2%. Induction of SARA reduced the 24- and 48-h in situ neutral detergent fiber (NDF) degradabilit...
متن کاملDigestibility and ruminal digestion kinetics of corn silage
The in situ dry matter (DM) disappearance of corn silages in two maturity stages (milk grain and half milk line) of known in vivo and in vitro digestibility was determined, with the main purpose of comparing digestibility values with the ruminal disappearance at 24 and 48h of incubation. A secondary goal was the description of their ruminal digestion kinetics, from which the effective degradabi...
متن کاملEffects of chewing behavior and ruminal digestion processes on voluntary intake of grass silages by lactating dairy cows.
Four primiparous Holstein-Friesian cows (518 kg average BW) with ruminal and duodenal cannulas were used to examine voluntary intake of direct cut (DC) or wilted (W) grass silage in relation to ruminal characteristics and chewing behavior. Dry matter content of the silages was 17.0 and 38.1%, concentrate DM intake was restricted to 5.0 and 5.3 kg/d, and voluntary DM intake from silages averaged...
متن کاملEffects of ruminal or postruminal fish oil supplementation on intake and digestion in dairy cows.
The effect of fish oil supplementation on intake, digestibility and the volatile fatty acid profile in dairy cows was investigated in two trials. In each of the two trials, six cows received a diet based on maize silage in a latin square design. In the first trial, the cows were fitted with ruminal and duodenal cannulae and their diet was either supplemented or not with 300 mL fish oil and infu...
