“…Nigm et al [ 9 ] also concluded that HG was the best measurement to predict rib weight in Merino sheep. Additionally, in buffalo calves, Rashad et al [ 31 ] found that HG was highly correlated with all carcass traits.…”

The aim of this study was to predict carcass traits of Santa Inês lambs finished in tropical pastures by using biometric measurements. Data originated from two experiments involving 56 lambs (32 in experiment I and 24 in experiment II). In both experiments, the sheep were finished in that were finished in pastures of Panicum maximum and Brachiaria brizantha, experiment I being conducted in the rainy season and experiment II in the dry season. The following biometric measurements were recorded before slaughter: body length (BL), withers height (WH), rump height (RH), thorax width (TW), rump width (RW), chest width (CW), heart girth (HG), thigh circumference (TC), rump circumference (RC) and leg length (LL), in addition to live weight at slaughter (SW). After slaughter, hot carcass weight (HCW), cold carcass weight (CCW) and the weights of primal cuts (shoulder, neck, loin, leg and rib) were recorded. In the equations generated to predict SW, HCW and CCW, R2 ranged from 0.58 to 0.91 and the measurements of WH, TC, CW, HG and RW were the most relevant. In the equations developed to predict the weight of primal cuts, in turn, R2 ranged from 0.26 to 0.99. In these models, SW, BL, CW, TC, LL and HG explained most of the variation in the weight of primal cuts. Biometric measurements can be used to accurately and precisely predict HCW, CCW and the weight of primal cuts from the carcass of Santa Inês sheep finished in tropical pastures, since the equations presented R2 and correlation coefficient and agreement above 0.8.

“…Diets that have a lower proportion of concentrate (i.e., higher content of neutral detergent fibre) result in a longer retention of the digesta in the gastrointestinal tract of the animal, causing a high rumen content to be present at the time of weighing, negatively interfering with the carcass yield (Cifuni et al, 2014). In addition, buffalo slaughtered with higher body weights have higher hot and cold carcass yields (Rashad et al, 2019). The averages obtained in this study for carcass yields were lower than that observed by Cabral Neto et al (2013), which were 48.3 and 47% for hot and cold carcass yields, respectively, for Mediterranean buffalo in a feedlot.…”

The objective of this study was to evaluate the influence of diets with increasing concentrate levels on performance, carcass characteristics, and meat quality of Murrah buffaloes in feedlot. Twenty-four animals, with an initial body weight of 240 ± 50.5 kg and mean age of 9 months, were distributed to four treatments: 20%, 40%, 60% and 80% concentrate. After 114 days, the animals were weighed, slaughtered, and meat quality and performance data were submitted to analysis of variance and regression. The dry matter intake and average daily gain increased linearly. The final body, hot carcass, and cold carcass weights responded linearly to increases in concentrate level. The subcutaneous fat thickness, protein, and ether extract of meat increased linearly with an increase in concentrate level. The colour parameters, cooking losses, and shear force of the meat were not affected by increasing the concentrate. The inclusion of concentrate in feedlot diets increases performance, characteristics of carcass, and meat quality of Murrah buffalo in a feedlot.

“…Also, this latter author found that GC was a good predictor of the primary commercial cuts, accounting for 45% to 67% of the variation. In buffalo calves, Rashad et al [29] found that the GC had a high correlation with all carcass characteristics except bone weight; but was the best predictor of boneless meat and carcass fat weights (r 2 = 0.90, 0.78). In Pelibuey ewes, Bautista-Díaz et al [8] reported that BM can be used to predict the carcass tissue composition (in weights).…”

The present study was designed to evaluate the relationship between the body measurements (BMs) and carcass characteristics of hair sheep lambs. Twenty hours before slaughter, the shrunk body weight (SBW) and BMs were recorded. The BMs involved were height at withers (HW), rib depth (RD), body diagonal length (BDL), body length (BL), pelvic girdle length (PGL), rump depth (RuD), rump height (RH), pin-bone width (PBW), hook-bone width (HBW), abdomen width (AW), girth (GC), and abdomen circumference (AC). After slaughter, the carcasses were weighed and chilled for 24 h at 1 °C, and then were split by the dorsal midline. The left-half was dissected into total soft tissues (muscle + fat; TST) and bone (BON), which were weighed separately. The weights of viscera and organs (VIS), internal fat (IF), and offals (OFF—skin, head, feet, tail, and blood) were also recorded. The equations obtained for predicting SBW, HCW, and CCW had an r2 ranging from 0.89 to 0.99, and those for predicting the TST and BON had an r2 ranging from 0.74 to 0.91, demonstrating satisfactory accuracy. Our results indicated that use of BMs could accurately and precisely be used as a useful tool for predicting carcass characteristics of hair sheep lambs.
