Book excerpt: Residual feed intake (RFI) is a measurement of feed efficiency and is becoming a popular trait used in genetic selection. This study evaluated the effects of RFI classification on beef cattle performance, carcass and meat quality and its repeatability between growing and finishing phases of production. Cattle were managed on two different nutritional management regimens consisting of finishing on a high grain diet or backgrounding cattle prior to being finished on a high grain diet. Extensive RFI reranking occurred between production phases. Reranking was positively correlated with longissimus muscle area but did not influence other carcass and meat quality parameters. Growing phase RFI classification had a minimal effect on carcass traits, while low RFI classified steers in the finishing phase produced bigger ribeyes. High RFI steers produced juicier and more tender beef compared to low RFI steers assessed using taste panel and consumer evaluations.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A high moisture corn/soybean meal-based finishing ration was used to examine the effects of roughage source (corn silage, alfalfa hay), level of dietary roughage (8, 16, 24%), and ractopamine supplementation (none, Optaflexx) on growth performance, carcass traits, and beef quality for finishing 108 steers and 24 heifers (initial BW = 308 kg). Cattle were allocated by gender to 12 management regimen subclasses. Optaflexx (trade name for ractopamine hydrochloride) was fed over the last 28 d on feed with cattle marketed after common days on feed. Growth performance (ADG, feed intake, and feed efficiency) and carcass traits were assessed on an individual animal basis. A primal rib and semitendinosus (ST) muscle from each animal were processed at the University of Guelph Meat Laboratory for carcass and meat quality evaluations. Tenderness was determined using shear force assessment of product aged 7, 14, and 21 d. Average daily gains were similar (P > 0.27) across main effects while use of corn silage as the roughage source decreased (P 0.001) dry matter intake and improved (P 0.001) feed efficiency compared to feeding alfalfa hay. Roughage level and beta agonist supplementation did not affect (P 0.13) dry matter intake or feed efficiency. When the last 28 days on feed were examined, Optaflexx supplementation increased (P 0.001) weight change, ADG, and improved feed conversion, while DMI remained unchanged (P 0.373). Carcass traits including hot carcass weight, grade fat, longissimus muscle area, marbling, and body composition as assessed by rib dissection (% lean, fat, bone) were not affected (P 0.14) by roughage level, source, or use of Optaflexx. Fat partitioning and liver abscess scores were unaffected (P > 0.09) by source and level of roughage fed, and use of Optaflexx. Source and level of dietary roughage did not affect color (P > 0.21) or shear force (P > 0.20) values for longissimus (LM) and semitendinosus (ST) steaks. Lower DMI and better feed conversion can be achieved using corn silage as the roughage source, while inclusion of up to 24% roughage in finishing diets may not negatively impact gains, carcass characteristics or beef quality. Beef producers may be able to increase amounts of roughage in the diet to lower cost of production without compromising growth performance and carcass and meat quality.

Trejo and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred and fifty eight Angus (A), Simmental (S), Angus-Simmental, and Simmental-Angus steers across two years across were classified into high (H), medium (M), and low (L) residual feed intake (RFI) groups. Steers in the H RFI group ate 1 kg more of DMI (P 0.05) per day than steers in the L and M RFI group. Steers in the L RFI group had the highest feed efficiency by gaining 15% and 22% more per kg of feed than steers in the M and H RFI groups, respectively. Steers in the L RFI group had a phenotypic advantage for growth rate of 0.20 kg/d more (P 0.05) than steers in the M and H RFI groups. Steers in the H RFI group had carcasses with more kidney, pelvic, and heart fat than carcasses of steers in the L and M RFI group. No differences were observed (P = 0.89) among RFI groups for meat tenderness using the Warner Bratzler shear force method. Breed of dam exhibited some differences for initial (P

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to evaluate the effects of residual feed intake (RFI) classification on performance, feed efficiency, feeding behavior and carcass traits, and to determine the relative importance of individual performance and carcass measurements on between-animal variation in net revenue of feedlot steers. Performance, feed intake and feeding behavior traits were measured in 508 Angus-based composite steers, using the GrowSafe feed-intake measurement system, while fed a high-grain diet for 70 days. Residual feed intake (RFI) was computed as actual minus expected dry matter intake (DMI) derived from regression of DMI on average daily gain (ADG) and mid-test BW0.75, and steers classified into low (n = 150), medium (n = 200) and high (n = 158) RFI groups. Following the feed-intake measurement periods, steers were fed the same diet in group pens and harvested at an average backfat thickness of 1.14 cm. Net revenue (NR) was calculated as carcass value minus feeder calf, yardage, and feed costs using 3-year average prices. Feed cost was based on actual feed consumed during the feed-intake measurement periods, and model-predicted intake adjusted for RFI during the group-feeding periods. Steers with low RFI had $48/hd lower (P
