By-products from oil palm can feed ruminants such as fronds (OPF) and sludge (PS). Judging its continuous, cheap, abundant availability the industry, well a source of fiber or component in complete for ruminants, it is potential that be used animal feed. However, use livestock production minimal due to their complex structure, high lignin content, low protein content. So, needs management techn...

The Kunitz trypsin inhibitor (KTI) and the Bowman-Birk inhibitor (BBI) of trypsin and chymotrypsin contain disulfide bonds. Glycinin, the major storage protein in soybeans also contains disulfide bonds. Treatment of soy white flour with a NADP-thioredoxin system (NTS) effectively reduced disulfide bonds in soy flour and increased protein digestibility by trypsin and pancreatin as measured by th...

1The Alberta Crop Industry Development Fund is acknowledged for funding the project. 2Corresponding author: [email protected] ABSTRACT: The CP digestibility is traditionally measured by chemical analyses of CP and marker concentration in digesta and diets. Potentially, CP digestibility can also be predicted by marker concentrations and spectral analyses of digesta and diet. Spectroscop...

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 ...

Two completely random digestion trials were conducted, each with 12 beef steers (325 kg initial weight), to measure changes in digestibilities of fat and of forage components when fat was added to diets containing 62 to 76% wheat straw. Trial 1 diets contained either no added fat or 6.3% added fat from whole cottonseed (30% of the diet), cottonseed oil or animal fat; diets were formulated to co...

Twenty-four cecectomized and 24 intact White Pekin ducks were used in two experiments to assess the influence of cecectomy on ME and amino acid digestibility of several feed ingredients for ducks. Corn and soybean meal (SBM) were evaluated in Experiment 1, and bakery meal (BM), red dog (RD), and wheat middlings (WM) were evaluated in Experiment 2. Nitrogen-corrected true metabolizable energy an...

Corn silage is a major forage crop in Idaho, supporting its dairy industry. Corn silage produces more digestible energy per acre than other forages. Nutritionally, corn silage is palatable when ensiled properly, and high in energy because it typically contains 50% corn grain. Digestibility of starch declines as the kernel matures. Effective roller processing of corn silage ensures that most of ...

Alfalfa is the most planted perennial legume in world due to its high nutritive value, protein content, productivity, and digestibility addition vitamin mineral content. It also one of hardest plants ensile owing low reducible sugar dry matter (DM) contents buffering capacity. In this study, effects inoculation with Lactobacillus bifermentans which homofermentative brevis heterofermentative on ...

Experiments were conducted to evaluate the nutritional value of yellow-seeded rapeseed meal (YRSM). In the first experiment nutrient retention was recorded by 48 Arbor Acres-broiler chickens (28-d old) to determine AMEn (nitrogen-corrected apparent metabolizable energy), coefficient of apparent protein digestibility based on ileal digesta nitrogen, excreta nitrogen and uric acid nitrogen. The s...

The objectives were to determine if the in vitro dry matter (DM) digestibility was similar by using a traditional method compared to the new DAISYII system and to determine if in vitro DM digestibility was similar for sources of inoculum from two different donor cow diets, all forage or total mixed ration. Ten feeds were digested by the traditional method, the DAISYII method with same feeds in ...
