Ileal 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 کاملEffects of feeding frequency on intake, ruminal fermentation, and feeding behavior in heifers fed high-concentrate diets.
Four ruminally fistulated Holstein heifers (BW = 385 +/- 6.2 kg) were used in a 4 x 4 Latin square experiment to determine the effect of feeding frequency on intake, water consumption, ruminal fermentation, and feeding and animal behavior. The treatments consisted of different feeding frequencies: a) once daily (T1); b) twice daily (T2); c) 3 times daily (T3); and d) 4 times daily (T4). Heifers...
متن کاملEffects of an extract of plant flavonoids (Bioflavex) on rumen fermentation and performance in heifers fed high-concentrate diets.
UNLABELLED To study the effects of an extract of plant flavonoids [Bioflavex (FL)] in cattle fed high-concentrate diets, 2 experiments were designed. In the first experiment, the effects of Bioflavex on the development of rumen acidosis was evaluated in 8 Holstein-Friesian crossbreed heifers (451 kg; SEM 14.3 kg of BW) using a crossover design. Each experimental period lasted 22 d; from d 1 to ...
متن کاملEffects of clinoptilolite on rumen fermentation, digestion and feedlot performance in beef steers fed high concentrate diets.
In a 148-d feedlot experiment, 48 crossbred steers were fed a 70% sorghum diet with clinoptilolite (CLN), a natural zeolite, substituted at 0, 1.25 and 2.5% of the diet dry matter. No differences (P>.05) were detected in average daily gain, feed intake (dry matter and organic matter) and feed efficiency among treatments. Negative correlations (P<.05) between fecal starch and fecal pH were detec...
متن کاملEffects of fiber source on apparent digestibility and ruminal fermentation parameters in sheep fed high-concentrate diets
Sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). Diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, T1), 35% wheat straw (T2), 35% barley straw (T3) or 35% maize straw (T4). Total-tract apparent digestibility for dry matter, organic matter...
