Apparent digestibility of nitrogen and nitrogen retention of forages fed to steers in metabolism stalls.
Holstein steers in metabolism stalls were utilized to determine apparent digestibility of N (DN), N retention (NR) expressed as a percentage of total N consumed, and Mcal/kg digestible energy (DE) when diets of seven different classes of forages were fed. The best predictive equation for digestibility of N in the 153 forages studied was DN(%) = -98.1065 + 11.4724 (%CP) + 41.4475 (DE) - .1498 (%...
متن کاملEffect of Applying Ammonia or Fibrolytic Enzymes to Bermudagrass Hay on Feed Intake, Digestibility, and Growth of Beef Steers
This study evaluated the effects of the method of applying a commercial fibrolytic enzyme, Biocellulase A20 (A20), or ammonia to bermudagrass hay on the feed intake, digestibility, and growth performance of 50 AngusBrangus steers. Five-week fall regrowth of bermudagrass was harvested and treated with either anhydrous ammonia or A20 at rates of 3% dry matter (DM) and 15 g/ton of hay, respectivel...
متن کاملEffect of direct-fed fibrolytic enzymes on the digestive characteristics of a forage-based diet fed to beef steers.
A study was conducted to examine the method of delivery of a solution containing cellulases and xylanases on the digestion of a forage-based diet. Five ruminally cannulated beef steers (536 kg BW) were randomly assigned to a control (CON) or one of four enzyme treatments in a 5 x 5 Latin square experiment. Steers were fed a 70:30 (DM basis) grass hay:barley diet. Enzyme-treated rations containe...
متن کاملPerformance of Lactating Dairy Cows Fed Yeast and Fibrolytic Enzymes
We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture of Saccharomyces cerevisiae) and various amounts of FP800 (a fibrolytic enzyme mixture) on lactation performance. Treatments were arranged in a 4 × 2 factorial design consisting ...
متن کاملNutrient value of spray field forages fed to pigs and the use of feed enzymes to enhance nutrient digestibility.
This study determined the DE, ME, apparent total tract digestibility (ATTD) of N, and N retention of spray field forages (Bermuda grass, forage sorghum, and sweet sorghum) fed to pigs and the effects of the supplemental feed enzymes on energy and N utilization. A basal diet was formulated with 96% corn and 4% amino acids, minerals, and vitamins. Test diets contained 85% basal diet + 15% Bermuda...
