Utilization of Aspen Pellets as a Partial Roughage Replacement for Lactating Dairy Cows
… to determine if aspen could serve as a partial roughage for lactating dairy cows. All cows were at least 80 days into lactation at the start of the trial. Aspen contained on a DM basis, 1.9% crude protein, 80.3% neutral detergent fiber, 64.5% acid detergent fiber, and 16.88% lignin. There were …

Responses of Rumen Microflora to Whey Products Added to High-Grain Low-Roughage Rations
… rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and energy, the bacteria and protozoa numbers could population is a good indication of efficient feed utilization. Good growth of the rumen …

Prediction of optimal rumen degradable protein levels in no-roughage, corn-based feedlot diets
… AT AUTHOR'S REQUEST.] The need to balance no-roughage, corn-based feedlot diets for rumen degradable protein inclusion is essential in the feedlot setting. Five crossbred steers were fitted with ruminal and duodenal cannulas and used in a 5x5 Latin square design experiment. Dietary treatments …

Effect of roughage to concentrate ratio on ruminal fermentation and protein degradability in dairy cows
… roasted soya. The three treatments differed in roughage:concentrate ratio, being 60:40 (Treatment UP 60), 45:55 (Treatment UP 45) and 30:70 (Treatment UP 30). Intake of dry matter (DM) (kg/day) did not differ between treatments. The mean rumen pH in cows receiving the three experimental diets …

The value of limited grain-high roughage rations and cud inoculation for raising dairy calves
Under the conditions of this study, the following conclusions seemed justified: 1. Cud inoculations did not improve rate of growth or efficiency of feed utilization in calves through four months of age. Consumption of hay was not materially increased by cud inoculations. 2. Thus. it is concluded …

The Lipid Composition of Milk as Affected by High Grain-Limited Roughage Rations Containing Whey Products
… A high grain ration fed with a limited amount of roughage tends to cause a depression in milk fat production while at the same time changing the milk fat composition. There have been various attempts to alleviate the depression in milk fat. Minerals used in the ration seem to slightly relieve the …

Composition and digestibility of untreated and sodium hydroxide treated fecal waste from cattle fed high or low roughage rations
… study was conducted to investigate the effect of roughage level in the diet of steers producing fecal waste, drying method and NaOH treatment, on in vitro dry matter digestibility of cattle fecal waste. All three factors significantly (P<.01) affected in vitro dry matter digestibility of cattle …

Energy Status of Steers Dictates Effectiveness of Glycerol Inclusion in High-Roughage and High-Concentrate Feedlot Diets
<p>The objective of this research was to determine how to use glycerol as an effective source of energy in ruminant diets. Steer calves were used in a 56 d backgrounding study (n=128; Initial BW=340 ± 15 kg) and 105 d finishing study (n=120; Initial BW=420 ± 20 kg). Dietary treatments during …

Ruminal degradation of protein and carbohydrate using a batch culture system, and response to roughage removal, rumen modifier inclusion and postruminal amino acid supply in feedlot cattle
… culture system, demonstrate and responses to roughage removal, rumen modifiers inclusion and postruminal amino acid supply in feedlot cattle. The objective of the first study was to characterize rumen N, starch, and NDF degradation rate (k[subscript d]), and further calculate ruminal …

The effects of various nutritional factors on the composition of milk
… of concentrate and level of concentrate and roughage on milk composition; changes in certain blood and rumen constituents; and efficiency of conversion of feed protein to milk protein. Trial A (63 days) employed two groups of six cows each. The following rations were fed: 1) Control …

Inclusão de volumoso para bovinos de corte terminados com dietas de alto grão
… to evaluate three diets with 0%, 2.5%, and 5% roughage offered to cattle in 4 the finishing phase on feedlot. We used 1800 male Nellore animals divided into 12 pens in a 5 randomized block design with 150 animals each. Average daily gain, carcass yield, and 6 efficiency were calculated for all …

Feeding Behavior of Self-Fed Lambs
… in a 24-hour day for lambs fed a pelleted 20% roughage diet, a ground 20% roughage diet and a ground 40% roughage diet, respectively. Feeder usage was significantly less for lambs fed the pelleted diet, and the greatest animal performance and waste feed occurred with this diet.

Effect of nitrogen and energy supplementation on intake, digestibility and rumen fermentation efficiency in sheep fed poor quality Eragrostis curvula hay
… effects of starch and urea supplementation on roughage intake, digestibility, and microbial nitrogen synthesis (MNS) in sheep fed low-quality Eragrostis curvula hay (< 3% CP, 80% NDF; DM basis). In Trial 1, urea partially substituted the rumen degradable nitrogen (RDN) fraction of sunflower …

COMPARING VARIOUS FIBER SOURCES THROUGH MEASURING RUMINATION IN FINISHING BEEF CATTLE
… steers. The first study evaluated the effect of roughage source on rumination time and growth performance response in finishing beef steers. We hypothesized that roughage source would not affect rumination time and growth performance because dietary neutral detergent fiber (NDF) was similar …

Factors associated with milk fat secretion of cows in response to contrasting available energy consumption
… randomized according to milk production to (1) roughage ration (~22% CF) restricted to NRC; (2) concentrate ration (~12% CF) ad libitum; or (3) concentrate ration (~12% CF) restricted to NRC and fed for 30 days. Ad libitum concentrate showed higher dry matter intake (DMI), body weight (BW), milk …

Composition and in vivo and in vitro digestibility of cattle fecal waste
… of fecal waste from steers fed a ground, high roughage finishing ration. In the first trial steers were fed a basal ration containing approximately 50% roughage. The ration contained 14.3% crude protein and 22.8% crude fiber, dry basis. Apparent digestibility was 65% for dry matter and 66% for …

Utilization of wheat straw in rations for lactating dairy cows.
… of half of the alfalfa in rations containing 45% roughage for lactating dairy cows with chopped wheat straw does not adversely affect DM intake or milk yield and increase milk fat percentage. Replacing half of the long alfalfa with chopped alfalfa also apparently improved lactational performance …
