Two experiments were conducted to evaluate wheat middlings as a supplement for cattle consuming dormant bluestem-range forage. Effects of supplement type and amount were evaluated in Exp. 1, which consisted of feeding supplements of soybean meal:grain sorghum (22:78) or two different amounts of wheat middlings. Sixteen ruminally fistulated steers were blocked by weight (BW = 374 +/- 8.3 kg) and...

This study investigated the effects of replacing soybean meal (SM) with canola meal (CM) and decreasing crude protein (‎CP) levels in CM based diets on performance of dairy cows when different sources of processed grains and CM were used. Canola meal was untreated or roasted at 130°C for 30 minutes and grains sources (corn and barley) were either ground or steamed-flaked. Eight Holstein cows (‎...

Production responses obtained with supplemental protein from expeller soybean meal or corn by-products, relative to solvent soybean meal, were determined in three replicated 4 x 4 Latin square trials. Dietary forage (54 to 58% of DM) was solely alfalfa silage containing 30 to 55% DM and 21% CP (DM basis). Main concentrate ingredient was either ground shelled or high moisture corn; diets were fe...

the chemical composition, degradability coefficients (in situ) and ruminal-intestinal disappearance(mobile bag procedure) of dry matter (dm) and crude protein (cp) were evaluated for olive cake (oc)silages treated (dm basis) with additives as follows: (1) untreated oc, (2) oc + 0.5% urea, (3) oc + 0.4%formic acid, (4) oc + 8% molasses, (5) oc + 0.5% urea + 8% molasses, (6) oc + 0.5% urea + 0.4%...

The objective of this study was to investigate the effects of cut and irrigation water quality on chemical composition and in situ dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) degradability of alfalfa. Three fistulated Zel sheep (approximately 2 years old) were used in a complete randomized design to evaluate the in situ rumen degradability. Ruminal in...

Whole-crop wheat treated with 40 kg urea/t/DM was examined in two experiments as the sole forage offered ad libitum. The objective was to evaluate the nutritive value of the forage, and the response in milk production to energy and protein supplements. In Experiment 1, 12 Holstein Friesian lactating cows in three 4 4 Latin squares were offered four concentrates, AÐ6 kg/day of 208 g CP kg/DM, BÐ...

the objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (dm yield) and 5 quality traits such as dry matter digestibility (dmd%), water soluble carbohydrates (wsc%), crude protein (cp%), acid detergent fibre (adf%) and total ash in tall wheatgrass (agropyron elongatum). in th...
