Crude Protein, Crude Fiber, Tannin, and Oxalate Concentrations of 33 Astragalus Species

Crude protein fractionation and fiber analysis of commerical non-forage fiber sources for ruminants in central iran

Dietary crude protein and tannin impact dairy manure chemistry and ammonia emissions from incubated soils.

Excess crude protein (CP) in dairy cow diets is excreted mostly as urea nitrogen (N), which increases ammonia (NH) emissions from dairy farms and heightens human health and environmental concerns. Feeding less CP and more tannin to dairy cows may enhance feed N use and milk production, abate NH emissions, and conserve the fertilizer N value of manure. Lab-scale ventilated chambers were used to ...

Evaluation of analytical methods for the determination of moisture, crude protein, crude fat, and crude fiber in distillers dried grains with solubles.

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...

Carcass characteristics of feedlot lambs fed crude glycerin contaminated with high concentrations of crude fat.

Thirty non-castrated male lambs with 20±2.3 kg average body weight (BW) were randomly assigned to five treatments consisted of different dietary concentrations of crude glycerin (CG; 0, 3, 6, 9 and 12% on DM basis) to evaluate the effects on performance, carcass and meat quality traits. A quadratic effect was observed for performance (P=0.04), final BW (P<0.01) and hot carcass weight (P<0.01). ...

Effects of Reduced Crude Protein and Fiber Supplementation on Nitrogen and Phosphorus Utilization and Availability

In recent years, animal agriculture has been surrounded by concerns of environmental contamination and degradation. To reduce potential environmental hazards, researchers have tried various practices to reduce the amount of nutrients being excreted in swine manure and ammonia emissions from manure contributing to diminishing air quality. To prevent further environmental concerns, diet modificat...
