Widespread premature termination codon mutations (PTCs) were recently observed in human and fly populations. We took advantage of the population resequencing data in the Drosophila Genetic Reference Panel to investigate how the expression profile and the evolutionary age of genes shaped the allele frequency distribution of PTCs. After generating a high-quality data set of PTCs, we clustered gen...

Tall fescue (Festuca arundinacea Schreb.) is an important forage resource for beef (Bos taurus L.) production in the North–South transition zone. Recently, the cultivar ‘Jesup’ was released to provide improved stand survival when infected with a novel (nontoxic) endophyte marketed as MaxQ (Pennington Seed, Madison, GA), and warrants evaluation as a source of winter hay for beef cattle. Intake a...

Using nylon bag techniques, Cornell net carbohydrates and protein systems (CNCPS), scanning electron microscopy, the authors examined digestibility structure of Vicia ervilia (ervil, bitter vetch) after steam flaking, roasting, microwave processing. During in situ technique, samples were incubated at 0, 2, 4, 6, 8, 12, 16, 24, 36, 48 h. For description ruminal DM (dry matter) CP (crude protein)...

To examine the kinetics of carnitine palmitoyltransferase-I (CPT-I) and the influence of dietary variables, young pigs (18 kg, n 5 20) were fed corn-soybean meal diets supplemented with 40 g soy oil/kg and containing either 136 or 180 g crude protein/kg and either 0 or 500 mg/kg L-carnitine (2 3 2 factorial design). Diets were offered for 10 d (85% of ad libitum); CPT-I activities in liver and ...

A number of analytical methods for constituents commonly measured in distillers dried grains (DDG) are practiced in laboratories serving the agricultural sector. A large interlaboratory variability among results has been observed in the industry. Methods for moisture, crude fat, and crude fiber are empirical, thus part of this variability can be attributed to the use of different methods of ana...

The changes in crude protein, free amino acids, amino acid composition, protein solubility, protein fractionation and protein digestibility after germination of sorghum were investigated. Sorghum varieties (Dorado, Shandaweel-6, Giza-15) were soaked for 20 h followed by germination for 72 h; the results revealed that crude protein and free amino acids in raw sorghum varieties ranged from 10.62 ...

In this study, the effects of different cellulosic wastes on nutritional values Pleurotus ostreatus (Jacq.) P. Kumm. were investigated. Dry matter, moisture, protein, fat and ash contents analyzed according to AOAC methods. Crude protein determined by Kjeldahl method Soxhlet extraction, using ether as a solvent, respectively. Chemical composition such dry crude organic matter 93.5-93.7%, 6.3-6....

The effect of grape pomace (Vitis vinifera) and in oak leaf (Quercus libani) tannins by three runs of in vitro gas production on the organic matter digestibility (OMD) and in situ dry matter (DM) and crude protein (CP) disappearance were studied in four sheeps. Polyethylene glycol (PEG) was used to deactivate the tannins. In vitro gas production was recorded at 2, 4, 6, 8, 12, 48, 72, 96 and 12...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...
