Abstract Growth and carcass traits are the main breeding objectives in beef cattle. The aim of this study was to confirm genetic effects of the c.*188G>A SNP of AKIRIN2, the g.231054C>T SNP of TTN, the g.1471620G>T SNP of EDG1 and the g.70014208A>G SNP of MYBPC1 on growth and carcass traits in Chinese Qinchuan (QC) cattle, as well as to compare the frequencies of the well-characterized alleles of these SNPs among six Chinese cattle populations, three Japanese cattle populations, two European cattle populations and one Korean cattle population. In this study, a total of 665 cattle samples were genotyped using MassARRAY and PCR-RFLP. Association analysis explored effects of four SNPs on growth and carcass traits including body length, wither height, hip height, hip width, rump length, chest depth, chest circumference, back fat thickness, ultrasound longissimus muscle area and ultrasound longissimus muscle depth in QC (P<0.05 to P<0.001). The well-characterized A (c.*188G>A), T (g.231054C>T) and T (g.1471620G>T) alleles in Japanese Black cattle were significantly higher than Chinese cattle breeds, on the contrary, the G allele (g.70014208A>G) was markedly higher in Chinese cattle breeds than other cattle breeds. These results suggest that the four SNPs might be useful as a molecular marker for growth-related traits in Chinese QC cattle.

Abstract Growth performances are the main breeding objectives in Chinese beef cattle. The objective of this study was to confirm genetic effects of the c.*188G > A SNP in AKIRIN2, the g.231054C > T SNP in TTN, the g.1471620G > T SNP in EDG1, and the g.70014208A > G SNP in MYBPC1 gene on growth-related traits in Chinese Qinchuan cattle, as well as to compare the frequencies of the well-characterized alleles of these SNPs among six Chinese cattle populations, three Japanese cattle populations, two European cattle populations and one Korean cattle breed. In this study, a total of 655 cattle samples were genotyped using MassARRAY and PCR-RFLP. Association analysis indicated that the four SNPs have effects one to six indexes of growth-related traits including body length, wither height, hip height, hip width, rump length, chest depth and chest circumference in Chinese Qinchuan cattle (P < 0.05 to P < 0.001). The well-characterized A (c.*188G > A), T (g.231054C > T) and T (g.1471620G > T) alleles in Japanese Black cattle were significantly higher than Chinese cattle breeds, on the contrary, the G allele (g.70014208A > G) was markedly higher in Chinese cattle breeds than other cattle breeds. These results suggest that the four SNPs might be useful as a molecular marker for growth-related traits in Chinese Qinchuan cattle.

Abstract The goal of this study was to evaluate the performance and the carcass traits of Nelore cattle progenies from bulls selected by contrasting traits for precocity, growth and muscularity, through the Expected Progeny Difference (EPD). One hundred and five Nelore bulls (initial weight of 350kg±15kg) and 20 months of age were confined and fed with same diet (73% of concentrate). Thirty-two animals were selected to create the contrasting groups for precocity, growth and muscularity (16 animals assigned as a low EPD group - LEPD and 16 animals assigned as a high EPD group - HEPD), based on the EPD of their parents. The ribeye area and backfat thickness were performed by ultrasonography of 12–13th rib fat thickness and longissimus muscle area (LMA), as well as rump fat thickness (RF) measurements. Animals were harvested after 100 days and during the deboning, meat cuts were weight for cutting yield. The animals selected for the HEPD group had greater average daily gain (P = 0.006), which can be explained by the higher feed intake (P = 0.006). However, there are no difference between groups for the final body weight (P = 0.254) and feed efficiency (P = 0.715). The LEPD group presented higher dressing percentage (P = 0.028). Although the groups evaluated did not presented difference in LMA (P = 0.329) and weight of longissimus muscle (P = 0.480), the weight of rump displayed heaviest in the HEPD (P = 0.037). There was no difference between groups for RF (P = 0.086). Nevertheless, backfat thickness was higher in HEPD group (P = 0.006). The present study indicates that Nelore cattle progenies, with parents displaying higher potential for precocity, growth, and muscularity, show greater backfat thickness and weightiest of rump than the other genetic backgrounds.

Genetic Trends

The aim of this study was to evaluate the genetic variability, genetic and phenotypic associations, and genetic gains of birth (BW), weaning (WW), and yearling (YW) weights, loin muscle area (LMA), backfat thickness (BF), rump fat thickness (RF), scores of body structure (BS), finishing precocity (FS), and muscling (MS) in Nelore cattle. Genetic parameters were obtained through Bayesian inference using BLUPF90 programs. All studied traits showed genetic variability, with heritability ranging from 0.29 to 0.47. In all studied ages, weights presented positive genetic correlations with LMA (ranging from 0.13 to 0.53), being generally stronger in comparison with the other carcass traits analyzed (BF and RF). Similarly, weights were higher genetic associated with BS (0.47–0.92) than with FS (0.18–0.62) and MS (0.22–0.65), respectively. The BF and RF showed positive and moderate genetic associations with FS and MS (0.31–0.36). Genetic trends were significant (P < 0.05) and favorable for WW, YW, and visual scores. Selection for increasing BW, WW, YW, and LMA will result in modest or no change in BF and RF (correlated response ranging from −0.04 to 0.07 mm per generation). In this population, carcass traits must be included in the selection indexes to obtain genetic gains in carcass quality, if desired.

The aim of the authors was to evaluate changes in the longissimus muscle area (LMA) and rump fat thickness (P8) based on real-time ultrasound scanning in the Hungarian Simmental cattle breed. Ultrasonic measurements were carried out on the same 11 Hungarian Simmental fattening bulls by Falco 100 (Pie Medical) equipment (I.: age: 357±23.47 days, live weight: 475.55±51.40 kg; II.: age: 418±23.47 days, live weight: 555.10±54.11 kg) on two occasions. Animals were kept in small groups, on deep litter, and fed on silage and concentrate. LMA and P8 were measured on the scans, between the 12th and 13th ribs by manual outlining. Results for the investigated traits during the examinations were as follows: P8: I.: 0.373±0.154 cm, II.: 0.624±0.161 cm; LMA: I.: 65.72±5.89 cm2, II.: 71.74±8.94 cm2. During the fattening period, P8 increased significantly (I-II.: t=3.73, P<0.001). A significant positive correlation was calculated between results of measurements I. and II. in the case of LMA (r=0.71, P<0.05). Results imply the possibility of selling bulls with smaller LMA earlier, at lower body weight. Application of ultrasonic measurements in fattening technology could generate a more quality-related pricing system.

Forty Pelibuey × Kathdin lambs (35.5 ± 0.4 kg) were used in a 56-day feeding experiment to assess the effects of feeding different levels of chromium-enriched live yeast (Cr-YC) on growth performance, dietary energetics, carcass traits and visceral organ mass. The Cr-YC source contained 5.5 × 109 colony forming units (CFU) and 0.40 mg of Cr per gram. Treatments consisted of a dry rolled corn-based finishing diet supplemented with 0, 1, 2 or 3 g Cr-YC/lamb.day. Total daily dosages were: 5.5 × 109 CFU and 0.4 mg; 1.1 × 1010 CFU and 0.8 mg Cr, and 1.65 × 1010 CFU and 1.2 mg Cr for supplementation levels of 1, 2 or 3 g Cr-YC/lamb.day, respectively. There were no treatments effects on dry matter intake. As the level of Cr-YC supplementation increased, average daily gain, gain to feed and dietary net energy were linearly increased, and observed/expected dry matter intake was linearly decreased. Chromium-enriched live yeast supplementation increased empty bodyweight (EBW), gastrointestinal fill and full viscera weight, but did not influence organ weights as a proportion of EBW (g/kg EBW). Cr-YC level did not affect carcass length, backfat thickness, kidney, pelvic and heart fat or body wall thickness, but increased hot carcass weight and longissimus muscle area. In general, treatment effects on percentage yield of wholesale cuts (tissue weight as a percentage of cold carcass weight) were small. However, Cr-YC decreased percentage flank. Chromium-enriched yeast supplementation enhances growth rate, longissimus muscle area, and dietary energetic efficiency in finishing feedlot lambs.

Carcass quality characteristics were measured on 511 steers of 4 breeds that were destined for the Japanese market. All steers had carcass measurements taken at the 10th/11th rib interface, while 103 steers had additional measurements made on the same characteristics at the 5th/6th rib interface. Australian marbling score, longissimus muscle area, intramuscular fat percentage, intramuscular water content, Japanese intermuscular fat thickness, Japanese subcutaneous fat thickness, Japanese rib thickness, and meat pH were measured in the study. These measurements allowed the phenotypic relationships between the different carcass quality traits measured at the 10th/11th rib interface to be calculated. Significant positive correlations were observed among measurements of carcass fatness, and significant negative correlations were observed between carcass fatness and carcass water content. Angus and Murray Grey cattle had higher levels of marbling and intramuscular fat than Hereford and Poll Hereford cattle The data enabled Australian, USDA, and Japanese marbling standards to be compared on the basis of intramuscular fat percentage determined by an ether extraction process. Differences between the same carcass characteristics taken at 5th/6th and 10/11th rib interfaces of the longissimus dorsi were estimated from the 103 steers measured at both sites. Correlations between the rib sites were high for marbling, intramuscular fat, and intramuscular water, but low for longissimus muscle area, intermuscular fat thickness, and pH.

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.

This paper aimed to identify and evaluate the effects of sire breed on temperament and productive traits of different cross-breeds between Nellore (NE), Tabapua (TB), and Brahman (BR) bulls mated with Angus cows (AN), as well as the relationship between temperament and productive traits. The productive traits measured in this study include slaughter weight and post weaning weight gain. Temperament was assessed by flight-speed (FS). Carcass data collected in this study include hot carcass weight, hot carcass percentage, cold dressing percentage, carcass length, initial pH, ultimate pH, subcutaneous fat thickness and carcass longissimus muscle area. The sire breed effect was greater for slaughter weight. Hot carcass weight was not affected by the sire breed. The longissimus muscle area was larger for AN x TB and AN x NE crossbreeds than for AN x BR crossbreeds. Subcutaneous fat thickness and cold dressing percentage were not affected by sire breed. The offspring of NE, TB, and BR sires mated with AN cows had similar carcass measurements, except for the longissimus muscle area, which was smaller for offspring sired by the Brahman breed. The temperament trait was not influenced by sire breed.
