The effect of protein supplementation on nitrogen utilization in lactating dairy cows fed grass silage diets.
The study set out to examine the effects of supplementing grass silage with various levels of protein concentration and degradability on dietary nitrogen (N) excretion in lactating dairy cows consuming at least 60% forage. Six Holstein/Friesian cows in early to midlactation were offered six diets comprising two levels of crude protein (210 and 290 g/kg DM) and three levels of protein degradabil...
متن کاملThe effect of energy supplementation on nitrogen utilization in lactating dairy cows fed grass silage diets.
An experiment was conducted to examine the effect that various isoenergetic diets, containing different quantities of soluble carbohydrate and fiber and different types of starch, have on nitrogen (N) balances. Six lactating dairy cows in early to midlactation consuming grass silage diets with not less than 600 g/kg total DMI as forage were used in the experiment. Four concentrates were prepare...
متن کاملEvaluation of dairy food processing wash water solids as a protein source: III. Nitrogen utilization by heifers fed medium-concentrate diets.
Eight multicannulated heifers (average BW 415 +/- 34 kg) were used in a replicated 4 x 4 Latin square to evaluate fluid milk processing wash water solids (WWS) as a dietary N source. Heifers were fed corn/cottonseed hull-based diets containing soybean meal (control, 0% WWS N) or WWS replacing soybean meal at 33, 67, or 100% of supplemental dietary N. Total tract and ruminal DM and OM digestibil...
متن کاملIleal Antibiotic Administration and Dietary Nitrogen Level for Beef Heifers Fed High Concentrate Diets
Crude protein requirements of finishing cattle over 1000 lb are below 10 percent of dietary dry matter (NRC, 1976). However, crude protein is usually fed in excess of 10 percent of DM due to decreased feed intake and performance at lower protein levels. Finishing diets usually consist of cereal grains fed ad libitum. With milo and corn grains, substantial quantities of starch are not completely...
متن کاملCharacterization and Utilization of Zeolite for NPK Slow Release Fertilizer (RESEARCH NOTE)
Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...
