Effects of Programmed Feeding to a Constant Average Daily Gain vs. Ad Libitum Feed Intake on Performance and Carcass Characteristics of Finishing Beef Steers
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 ...
متن کاملProfile of the Spleen Transcriptome in Beef Steers with Variation in Gain and Feed Intake
We have previously identified components of the immune system contributing to feed intake and gain in both the rumen and small intestine of beef steers. In this study, we examined the spleen, a major lymphatic organ near the digestive tract, to determine whether it was also influencing individual feed efficiency status through immune responses. Animals (n = 16) that were divergent for gain and ...
متن کاملThe Effect of Delaying Initial Feedlot Implant on Body Weight, Average Daily Gain, and Carcass Characteristics of Calf-Fed Steers
Two experiments were conducted to determine the effect of delaying initial feedlot implant on BW, ADG, and carcass characteristics. At receiving, steers were assigned to 1 of 2 treatments: 1) implant at feedlot entry (NORM) or 2) implant 30 d after feedlot entry (DELAY). In Exp. 1, steers (n = 200) were not implanted until feedlot entry; however, in Exp. 2 steers (n = 209) were implanted at app...
متن کاملAre Breaks in Daily Self-Weighing Associated with Weight Gain?
Regular self-weighing is linked to successful weight loss and maintenance. However, an individual's self-weighing frequency typically varies over time. This study examined temporal associations between time differences of consecutive weight measurements and the corresponding weight changes by analysing longitudinal self-weighing data, including 2,838 weight observations from 40 individuals atte...
متن کاملBreed means for average daily gain, feed conversion and intake of beef bulls during postweaning feedlot performance tests.
Comparisons of ADG, feed/gain, daily feed intake and daily feed intake as percentage of body weight may be important to beef cattle producers and researchers in breed selection and computer modeling. Data evaluated were postweaning feedlot performance test records collected from 1967 to 1986 of 3,661 individually fed bulls. Bulls originated from University of Arkansas purebred herds, Fayettevil...
