PERFORMANCE OF BEEF STEERS FED GRASS SILAGE WITH OR WITHOUT SUPPLEMENTS OF SOYBEAN MEAL, FISH MEAL AND BARLEY

Comparison of whole, raw soybeans, extruded soybeans, or soybean meal and barley on digestive characteristics and performance of weaned beef steers consuming mature grass hay.

Two experiments were conducted to compare whole, raw soybeans (WSB), extruded soybeans (ESB), and soybean meal+barley (SBM+BAR) as supplemental protein sources for growing beef steers consuming low-quality, mature grass hay (6.5% CP). In Exp. 1, a 23-d digestion study, four ruminally cannulated steers were assigned to the following treatments in a 4 x 4 Latin square design: 1) control, no suppl...

Protein Supplementation of Ammoniated Roughages. II. Wheat Straw Supplemented with Alfalfa, Blood Meal or Soybean Meal Fed to Wintering Steers

Two winter steer growth trials were conducted to investigate responses of steer calves to ammoniation of wheat straw, level of alfalfa haylage (50 or 66.7% of diet) and source of supplemental protein, soybean meal (SBM), blood meal (BM), or a blood meal-urea mixture (BM-U). In trial 1, the main effect of arnmoniation significantly increased average daily gain (ADG) from .15 t o .24 kgld, dry ma...

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, ...

Effects of soybean meal or canola meal on milk production and methane emissions in lactating dairy cows fed grass silage-based diets.

This study evaluated the effects of soybean meal (SBM) and heat-moisture-treated canola meal (TCM) on milk production and methane emissions in dairy cows fed grass silage-based diets. Twenty-eight Swedish Red cows were used in a cyclic change-over experiment with 4 periods of 21 d and with treatments in 2 × 4 factorial arrangement (however, the control diet without supplementary protein was not...
