“…Also, treatment had no effect on ribeye area (P = 0.985), which is in agreement with other reports in the literature. Restricted intakes during the growing phase did not affect ribeye area (Loerch, 1990), and extended backgrounding did not affect ribeye area (Vaage et al, 1998). All carcass composition and quality traits, including 12th-rib fat, KPH, marbling score, and USDA quality and yield grades were unaffected by treatments (P ≥ 0.12).…”

“…Feeding strategy and length of the backgrounding can alter HCW as reported by Block et al (2001) who reported increased HCW when the length of the backgrounding period was increased and Vaage et al (1998) who found that forage-based diets resulted in increased HCW when compared with highenergy diets during the backgrounding period. Because the length of background time and the treatment diets were not substantially different, it is not surprising that there were not HCW differences.…”

“…Nutrition and management practices during the backgrounding phase are major contributors to finishing performance and carcass characteristics (Ralston et al, 1966). Previous researchers have studied the effects of backgrounding on differing breed types (Block et al, 2001), the effects of prolonged backgrounding on growth performance and carcass composition (Vaage et al, 1998), and the effects of backgrounding and growing programs on beef carcass quality (Klopfenstein et al, 1999). However, little research exists that examines the effect of rate of BW gain during backgrounding on finishing performance, carcass characteristics, and sensory traits.…”

“…Improved uniformity in slaughter cattle can be achieved by allowing calves to attain a greater BW before the start of the finishing phase (Vaage et al, 1998). Backgrounding calves before finishing can also increase mature size (Owens et al, 1993).…”

A.; Maddock, R. J.; Stamm, M. M.; Schauer, C. S.; Rush, Ivan G.; Quinn, S.; and Lardy, G. P., "Growing rate of gain on subsequent feedlot performance, meat, and carcass quality of beef steers" (2009 LG diet consisted of 52.5% barley silage, 39.0% whole shell corn, and 8.5% supplement, whereas the HG diet contained 43.9% barley silage, 47.4% whole shell corn, and 8.7% supplement (DM basis). Initial BW (226 kg) was not different (P = 0.70) between treatments. Steers fed the HG diet had increased ADG (1.67 vs. 1.40 kg/d; P < 0.001) compared with steers fed LG diet. Dry matter intake was greater (9.49 vs. 8.35 kg/d; P < 0.001) for steers fed the HG vs. LG diet. Total backgrounding cost ($/animal) was less (P < 0.001) for those steers fed LG diet compared with HG diet ($126.00 vs. $140.35, respectively); however, total cost per kilogram of BW gain was not different (P = 0.24; $0.485/kg of BW gain). After the backgrounding period, steers were fed a common finishing diet for 135 d. During the finishing period, LG steers had similar (P = 0.12; 10.73 vs. 10.35 kg/d) DMI compared with those fed HG diets; however, ADG was not different (1.55 kg; P = 0.72) among treatments. Hot carcass weight, marbling score, 12th-rib fat, LM area, and USDA yield grade were not different (P > 0.12) between treatments and averaged 363 kg, Sm 30 , 1.33 cm, 83.8 cm 2 , and 2.7, respectively. There were no differences (P = 0.77; 3.63 ± 0.12 kg) in WBSF tenderness of rib-eye steaks. Percent cooking loss was increased in LG diets (P = 0.017). No differences were observed in consumer sensory analysis of tenderness, juiciness, and flavor intensity (P ≥ 0.276; 5.43 ± 0.12, 5.07 ± 0.13, and 5.17 ± 0.05, respectively). These data suggest that feeding steers diets that differ in energy concentration and result in ADG of 1.4 and 1.7 kg/d during the growing period results in minimal changes in subsequent finishing performance and does not affect meat quality.

“…Other studies have shown higher rates of gain. Vaage et al (1998) reported that high grain fed (vs. backgrounded) steers had average daily growth rates of 1.62 (vs. 1.03) kg liveweight, 0.04 (vs. 0.02) mm 12/13th rib ultrasound fat depth, and 0.22 (vs. 0.11) cm 2 longissimus muscle area over the entire weaning to slaughter feeding period. However, figures indicated that diet differences became very slight late in the feeding period (Vaage et al 1999).…”

among indicator traits for carcass composition measured in yearling beef bulls and finished feedlot steers. Can. J. Anim. Sci. 85: 463-473. Genetic correlations were examined among 10 live growth and ultrasound traits measured in yearling beef bulls (n = 2172) and four carcass traits measured in crossbred finished feedlot steers (n = 1031). Heritabilities ranged from 0.13 (bull ultrasound longissimus muscle width) to 0.83 (yearling bull hip height). Genetic correlations indicated that selecting yearling bulls for increased growth rate and hip height would lead to higher carcass weight, increased longissimus muscle area and reduced levels of carcass marbling in steers. Bull ultrasound fat depth was positively associated with both carcass fat depth and marbling score. Most ultrasound longissimus muscle size measurements in bulls were positively associated with each other and with carcass longissimus muscle area in steers, but the magnitude of the genetic correlation with carcass measurements depended on the bull longissimus muscle size trait in question. This suggests that longissimus muscle shape in bulls may be related to carcass weight, fat and muscle traits in steers. Results confirm that while ultrasound is a valuable tool for the genetic improvement of carcass traits in beef cattle, genetic correlations between live bull ultrasound and steer carcass traits less then unity suggest that selection would benefit from multiple trait evaluations in situations where reliable carcass data are available. Les corrélations génétiques indiquent qu'en sélectionnant les bouvillons d'un an d'après un taux de croissance plus rapide et la hauteur aux hanches, on obtiendrait des carcasses plus lourdes, un longissimus d'une plus grande superficie et de la viande moins persillée. L'épaisseur du gras des bovins mesurée aux ultrasons présente une corrélation positive avec l'épaisseur du gras de la carcasse et le persillé. La plupart des mesures du longissimus obtenues aux ultrasons chez les bovins sont positivement corrélées les unes aux autres ainsi qu'avec la superficie de ce muscle dans la carcasse des bouvillons, mais l'importance de la corrélation génétique avec les mesures de la carcasse dépend du paramètre concerné des dimensions du longissimus chez l'animal adulte. On en déduit que la forme du muscle chez les bovins adultes pourrait dépendre de caractères régissant le poids de la carcasse, le gras et les muscles chez les bouvillons. Les résultats confirment que si l'analyse aux ultrasons a son utilité pour parvenir à une amélioration génétique des paramètres de la carcasse chez les bovins de boucherie, quand les corrélations génétiques entre les mesures prises sur l'animal vivant aux ultrasons et les paramètres de la carcasse des bouvillons ont une valeur inférieure à l'unité, la sélection profiterait d'une évaluation multifactorielle dans l'éventualité où on possède des données fiables sur la carcasse.
