Effect of Barley or Rape Seed Cake as Supplement to Silage for High-Yielding Organic Dairy Cows

Supplementing barley or rapeseed meal to dairy cows fed grass-red clover silage: I. Rumen degradability and microbial flow.

The present study was conducted to measure the flow of microbial and nonmicrobial N fractions entering the omasal canal of lactating dairy cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated Finnish Ayrshire dairy cows were fed, in a 4 x 4 Latin square design, grass-red clover silage alone or supplemented with (on DM basis) 5.1 kg/d of barley, ...

Effect of Feeding of Various Types of Soybean Meal and Differently Processed Barley Grain on Performance of High Producing Lactating Holstein Dairy Cows

Twenty-four lactating Holstein dairy cows were used in a completely randomized design to investigate the effect of soybean meal (SM) and xylose protected soybean meal (XSM) in combination with ground (GB) or steam flaked (FB) barley on dry matter intake, milk production, rumen fermentation and blood responses. The experimental period lasted for 30 days. The diets consisted of the provision of 1...

The effects of corn silage particles size and fat supplement on feed intake, digestibility, ruminal function, chewing activity, and performance in mid-lactating Holstein dairy cows

An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...

Effect of yeast culture supplementation of alfalfa silage or alfalfa hay fed to lactating dairy cows

Effects of pressed beet pulp silage inclusion in maize-based rations on performance of high-yielding dairy cows and parameters of rumen fermentation.

Beet pulp contains high amounts of pectins that can reduce the risk of rumen disorders compared to using feedstuffs high in starch. The objective was to study the effects of inclusion of ensiled pressed beet pulp in total mixed rations (TMR) for high-yielding dairy cows. Two TMR containing no or about 20% (on dry matter (DM) basis) beet pulp silage were used. The beet pulp silage mainly replace...
