Effects of Programmed Feeding to a Constant Average Daily Gain vs. Ad Libitum Feed Intake on Performance and Carcass Characteristics of Finishing Beef Steers
نویسندگان
چکیده
Thirty-two Angus steers were used in a 140d feeding trial to examine the effects of ad libitum feed intake or a programmed rate of gain on feedlot performance and carcass characteristics. Ad libitum-fed steers had greater (P < .06) DMI, ADG, and feed efficiency from d 0 to 28, 0 to 56, and 0 to 84 than programmed-fed steers; however, no differences in ADG, DMI, or feed efficiency were detected for the remainder of the feeding trial. Feeding regimen did not affect (P > .10) hot carcass weight, dressing percent, longissimus muscle area, marbling score, or yield grade. These data indicate that programmed feeding can be used to effectively manage intake by finishing beef cattle.

Effects of restricted feeding of growing steers on performance, carcass characteristics, and composition.
Two experiments were conducted to determine the effects of restricted feeding on performance, carcass characteristics, and composition. In Trial 1, 36 individually penned steer calves (280 +/- 13 kg BW) were fed all-concentrate diets at intake levels of ad libitum and 90 and 80% of ad libitum. Trial 2 used 36 individually penned steer calves (298 +/- 14 kg BW) fed corn silage-based growing diet...

Three experiments were conducted to determine effects of restricting intake of the final finishing diet as a means of dietary adaptation compared with diets increasing in grain over a period of 20 to 22 d on overall cattle performance, carcass characteristics, digestibility, digesta kinetics, and ruminal metabolism. In Exp. 1, 84 Angus x Hereford yearling steers (initial BW = 418 +/- 29.0 kg) w...

This experiment was conducted to determine the effect of programming the rate of gain and delaying the first implant in feedlot steers on feedlot performance and carcass characteristics. Ninety-six growing steers (269 ± 16.2 kg) were assigned to 12 pens in a completely randomized design. Treatments were implant (Synovex-S; 20 mg estradiol benzoate and 200 mg progesterone; Fort Dodge Animal Hea...

Two feedlot trials were conducted to evaluate the effects of feeding frequency (once daily in the morning, once daily in the afternoon or twice daily) and feeding level (ad libitum, 95% of ad libitum, or 90% of ad libitum) on the feedlot performance and carcass composition of beef steers. Data were collected using 196 yearling beef steers. In both trials cattle fed once daily in the morning ten...

1Department of Animal Sciences, NDSU The objectives of this study were to determine the effects of forage inclusion level on growth performance, feeding behavior and carcass characteristics in finishing steers. These results indicate that a decrease in forage inclusion from 20 to 5 percent (dry-matter [DM] basis) in a finishing diet increases dry-matter intake (DMI), average daily gain (ADG) an...
