Ruminal ammonia load affects leucine utilization by growing steers.
Six ruminally cannulated Holstein steers (initial BW = 189 +/- 11 kg) housed in metabolism crates were used in a 6 x 6 Latin square to study effects of ruminal ammonia load on Leu utilization. All steers received a diet based on soybean hulls (2.7 kg of DM/d), ruminal infusions of 200 g of acetate/d, 200 g of propionate/d, and 50 g of butyrate/d, as well as an abomasal infusion of 300 g of gluc...
متن کاملEffects of ammonia load on methionine utilization by growing steers.
Seven ruminally cannulated Holstein steers (194 +/- 16 kg) housed in metabolism crates were used in a 6 x 6 Latin square, with one additional steer, to study effects of ruminal ammonia load on methionine (Met) use. All steers received a diet based on soybean hulls (2.6 kg DM/d), ruminal infusions of 200 g/d of acetate, 200 g/d of propionate, and 50 g/d of butyrate, as well as abomasal infusion ...
متن کاملEfficiency of lysine utilization by growing steers.
This study evaluated the efficiency of Lys utilization by growing steers. Five ruminally cannulated Holstein steers (165 ± 8 kg) housed in metabolism crates were used in a 6 × 6 Latin square design; data from a sixth steer was excluded due to erratic feed intake. All steers were limit fed (2.46 kg DM/d), twice daily, diets low in RUP (81% soybean hulls, 8% wheat straw, 6% cane molasses, and 5% ...
متن کاملAnhydrous Ammonia Injection Depth Does Not Affect Nitrous Oxide Emissions in a Silt Loam over Two Growing Seasons.
Anhydrous ammonia (AA) is a major fertilizer source in North America that can promote greater emissions of nitrous oxide (NO) than other nitrogen (N) fertilizers. Previous studies found that injection of AA at a shallow depth (0.1 m) decreased NO in a rainfed clay loam but increased NO in an irrigated loamy sand compared with the standard injection depth of 0.2 m. The objective of this study wa...
متن کاملEffects of diaryliodonium chemicals on nitrogen utilization in growing steers.
Diaryliodonium chemicals increased nitrogen (N) absorption, utilization of absorbed N and N retention in growing steers. Fifty parts per million of the chemicals (diphenyliodonium chloride, diphenyliodonium bromide, 4,4'-difluorodiphenyliodonium chloride or 4,4'-dimethyldiphenyliodonium chloride) in the diet appeared sufficient to promote significant (P less than .05 or .10) improvements in N u...
