Effects of ruminally protected choline and dietary fat on performance and blood metabolites of finishing heifers.
A 120-d finishing study utilizing 318 heifers (342 kg initial BW) was conducted to examine effects of ruminally protected choline (RPC) in diets containing graded concentrations of tallow. Heifers were blocked according to previous nutrition (full-fed or limit-fed) and allotted to 24 pens containing 11 to 15 heifers. Two pens, one within each block, were assigned to each of 12 factorially arran...
متن کاملEffects of Source and Level of Ruminally Protected Choline on Performance and Carcass Characteristics of Finishing Beef Steers
Previous research (Galyean et al., 1997) indicated that daily gain and feed efficiency were improved when finishing beef steers were fed graded levels of ruminally protected choline (RPC; .25, .5, and 1% of dietary DM). Responses were cubic (P < .10) in nature, with an 11% increase in daily gain and a 6.8% improvement in feed efficiency for .25% RPC vs the control diet, but no effect on gain or...
متن کاملDegradable Intake Protein In Finishing Diets Containing Dried Distillers Grains
Fifty-eight crossbred yearling heifers (BW = 383 ± 25 kg) were utilized in a completely randomized 2 x 2 factorial arrangement of treatments designed to evaluate the effects of finishing diets containing dried distiller's grains supplemented with degradable intake protein on feedlot performance and carcass characteristics. Dietary treatments contained 10 or 20% dried distiller's grains (DDG) re...
متن کاملEffects of dietary level of ruminally protected choline on performance and carcass characteristics of finishing beef steers and on growth and serum metabolites in lambs.
Ruminally protected choline (RPC) was evaluated in two experiments. In Exp. 1, beef steers (n = 160; average initial BW = 350.9 kg) were fed a 90% concentrate diet with either 0, .25, .5, or 1.0% RPC (DM basis) for 112 to 140 d. Feeding .25% RPC increased ADG 11.6% compared with 0% RPC, but responses diminished with increasing RPC level (cubic response, P < .10). Daily DMI was not affected by R...
متن کاملEffect of degradable intake protein level on finishing cattle performance and ruminal metabolism.
Two finishing trials and a metabolism trial were conducted to evaluate level of supplemental degradable intake (crude) protein (DIP) in finishing diets on cattle performance, carcass characteristics, and ruminal metabolism. Finishing trials were conducted in two consecutive years using 128 crossbred yearling steers (BW = 343+/-5 kg, Trial 1) and 176 crossbred yearling steers (BW = 375+/-4 kg, T...
