Urea Utilization by Cattle as Influenced by Casein

Utilization of Urea and Urease Treated Rice Straw by Indigenous Growing Cattle

The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...

Normal hematological values of native iranian cattle as influenced by age,breed and sex

Utilization of nitrogen from soybean meal, casein, zein, and urea by mature sheep.

The utilization of nitrogen contained in soybean meal, casein, zein, and urea was studied in 12 mature wethers. Net microbial synthesis rates during the 6-hour period after feeding corresponded to ruminal ammonia concentrations, suggesting that the ruminal ammonia level in these experiments was a limiting factor in microbiol protein synthesis. Maximum conversion of dietary nitrogen to microbial...

Utilization of DDGS by Cattle

Distillers grains with solubles (DDGS), the major byproduct of ethanol production, is a good protein and energy feed for cattle. The DDGS can be fed wet or dried with animal performance usually similar when fed as wet or dried products; however, some research results favored the wet products. Cattle diets can contain DDGS as replacements for portions of both concentrates and forages, although D...
