A study was conducted to characterize the carbohydrate and protein fractions of barley-based distillers grains (BDG) derived from a mix of 70% barley, 20% wheat and 10% rye/triticale. Amino acid composition, ruminal escape protein and amino acid values, and ruminal nutrient degradability of BDG were determined relative to wheat-based distillers' grains (WDG) derived from 100% wheat. On a dry ma...

The aim of the present study was to evaluate fermentative profile, chemical composition, and in situ degradability total mixed ration silage with or without babassu byproducts formulated for sheep diets. experiment performed a completely randomized design, four treatments (silages) five replications (silos). were SS: sugarcane (control); SSCS: corn soybean meal; SSBF: corn, meal, flour; SSBC: c...

This study was conducted to evaluate the effects of infrared irradiation for 60, 90, 120 and 150 seconds on starch degradability and chemical compositions of corn grains. Three ruminally fistulated rams were used to measure in sacco degradation. There was a linear increase in DM of irradiated corn grains (P<0.001). Infrared irradiation decreased potentially degradable fraction and constant degr...

Cistus ladanifer L. (CL) is a perennial shrub abundant in dry woods and dry land of Mediterranean zone, with high level of tannins. Tannins bind to protein, preventing its degradation in the digestive compartments. This tannin/protein complex may be advantageous when partially protecting good-quality feed protein from excessive rumen protein degradation. The objective of this trial was to use a...

The objective of this study was to determine the undegradable dietary protein requirements of veal calves. Two experiments were carried out with Holstein bull calves from 3-10 days of age until slaughter at 20 weeks of age. Both experiments were divided into starter and finishing periods. Calves were offered starter pellets on an ad lib. basis from seven days of age. Diets were formulated to be...

Effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing 250 g/Kg wheat bran, were investigated. on broiler performance and phosphorus degradability and nitrogen digestibility. Phytase (500 and 1000 FTU) and xylanase (2700 and 5400 EXU) individually and in combination were added to the basal diet and given to 6 replicate groups (4 birds per replicate). At 21 day...

The objective of the study was to quantify annual and seasonal differences in the chemical composition, in vitro gas production, in situ degradability and ruminal fermentation of grazing steers' diets. Diet samples were collected with four esophageal cannulated steers (350±3 kg BW); and four ruminally cannulated heifers (342±1.5 kg BW) were used to study the dry matter degradation and fermentat...

Seven legume straws (Cicer arietinum, Vicia benghalensis, Vicia sativa, Vicia villosa, Vicia faba, Lens culinaris and Pisum sativum) were studied in rumen-cannulated rams. The chemical composition of the studied legume straws varied from 4.3 to 10.1% for ash, 6.1 to 11.4% for CP, 58.0 to 76.5% for NDF, 40.3 to 59.6% for ADF and 8.2 to 14.2% for ADL. Extent of degradation for DM and NDF by the n...
