The influence of monensin level (0, 6.1, 12.2, 18.3 and 36.6 ppm) on diet fiber digestibility, microbial protein synthesis and ruminal escape of dietary protein was evaluated in two steer metabolism trials. A growth trial was conducted to study possible interactions of forage quality and monensin level. In metabolism trial 1, four ruminal-cannulated steers were assigned to four monensin levels ...

Twelve ileal cannulated pigs (30.9 ± 2.7 kg) were used to determine the apparent (AID) and standardized (SID) ileal digestibility of amino acids in canola meals derived from black(BNB) and yellow-seeded (BNY) Brassica napus canola and yellow-seeded Brassica juncea (BJY). The meals were produced using the conventional prepress solvent extraction process (regular meals) or a vacuum-assisted cold ...

Introduction In rural areas of many tropical countries, pig production is a livelihood for smallholder farmers, who use the pigs as sources of income and food. The benefit of this livelihood is sometimes limited by high costs or the absence of balanced commercial diets, which often results in preparing diets with ingredients low in protein but high in fibre (e.g. banana, harvest by-products) (P...

Sixteen steers (650 Ib) were used to determine the effects of corn moisture, protein concentration and monensin (Rumensin) on ration digestibility and nitrogen retention. The steers were placed in metabolism stalls and fed rations of high moisture corn (HMC) or dry rolled corn at two protein levels (9.3 and 12.3 percent) with two monensin levels (0 and 30 g per ton of feed). Monensin addition d...

the possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. in first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. then, the sample product was analyzed to assess its chemical structure, and ...

Edible mushrooms used as a protein-rich food may be an attractive alternative to conventional protein sources, while promoting its valorization. This work aimed obtain concentrate from Pleurotus ostreatus mushroom flour, characterization, and nutritional functional properties evaluation. Methodologies applied for extraction precipitation of were optimized - pH 4 12, respectively; flour-solvent ...

Standardized ileal digestibility (SID) of AA in protein ingredients and grains was determined in weaned piglets (5 kg initial BW) using the difference method. Animals were fitted with a simple ileal T-cannula on day 24 or 25 of age. A synthetic diet based on corn (Zea mays) starch and casein was either supplemented with an extruded soybean (Glycine max) meal (ESM), rice (Oryza sativa) protein c...

Six yearling Hereford X Angus steers (avg 272 kg), each with ruminal, duodenal and ileal cannulas were used in a 6 X 6 Latin-square metabolism trial to evaluate the impact of NaHCO3 and trona (a ground, nonrefined ore with chemical composition NaHCO3-Na2CO3-2H2O) on site and extent of digestion of nutrients in the digestive tract. The diets were 50:50 or 90:10 (cracked corn-based concentrate:co...
