“…Several studies found a high and positive correlation between body measurements and body weight at slaughter (Fernandes Junior et al, 2015;Silva et al, 2016;Souza et al, 2014). In these studies, the body measurement with the highest correlation with body weight at slaughter was the chest circumference, and consequently this measurement was the one that best predicted body weight at slaughter.…”

This study evaluated the effect of replacing corn silage with spineless cactus, in combination with Tifton 85 hay or sugarcane bagasse, on the carcass measurements and sensory properties of the meat of lambs finished in feedlot. Twenty-one, intact, Santa Inês males, with an initial body weight of 22.86 ± 2.87 kg and an average age of 150 days, were individually confined for 74 days and fed at will three treatments diets: Corn silage (CS); Spineless cactus + Tifton 85 hay (CT) and Spineless cactus + sugarcane bagasse (CB). Lambs fed CT had a wider croup (p < 0.05) compared to animals fed CS. The replacement of corn silage with CT or CB did not influence (p > 0.05) the body length, withers height or chest circumference of the lambs. Values of carcass length and compactness index were similar (p > 0.05) between treatments. There was a high and positive correlation (p < 0.05) between chest width (0.82) and chest circumference (0.81) of animals with cold carcass weight. The odor and taste of sheep meat fed CT or CB was more accepted when compared to the meat of animals fed corn silage. The replacement of corn silage with spineless cactus in combination with Tifton 85 hay or sugarcane bagasse improves the sensory quality of sheep meat, but does not interfere with carcass measurements.

“…According to Marques et al (2008), CW is one of the biometric measures that can be used to predict live weight at slaughter in Santa Inês animals. However, Souza et al (2014) showed that despite the high correlation of CW with the live weight of lambs, it is less predictive of the body weight of these animals. However, in this study, the body weight (Table 2) of the animals and the increase in chest width showed a positive linear growth; that is, as the chest width increased, there was an increase in body weight.…”

“…Among the tools used to measure the productivity of small ruminants, body biometry (as a way of assessing the growth of animals), which, when analysed along with other zootechnical indexes, constitutes an important database for the individual evaluation of animals and to determine the evolution of the productive system (SOUZA et al, 2014). In addition, these in vivo biometric measurements have a high correlation with carcass measurements and, together with other zootechnical indexes, can help to predict some productive characteristics, such as weight, carcass yield and conformation, the proportion of muscles and adipose tissue, as well as the yield of cuts, orienting producers to the best time to slaughter their animals (MORENO et al, 2010;PINHEIRO et al, 2007).…”

Feed consumption has a great influence on the growth and performance of animals since the intake of dry matter supplies the quantity of nutrients that are necessary to meet the maintenance and production requirements of these animals. The objective of this study was to evaluate the dry matter intake, body growth, weight gain and carcass characteristics (by ultrasonography) of lambs fed an extruded ration at different roughage (R): concentrate (C) ratios. Thirty mixed race (Santa Inês x Dorper) lambs, aged 3 months and with an average weight of 20 kg, were used. The treatments consisted of an extruded ration in 30R:70C and 70R:30C ratios, completely randomised to 2 treatments and 15 replicates. The means of the variables were evaluated using a Tukey test and a regression at the 5% significance level. Dry matter intake (DMI), weight gain, body growth, evaluated through biometric measurements, and carcass characteristics, evaluated by ultrasonography, were assessed. There was a reduction of DMI in relation to body weight during the experimental period, with lower DMI amongst the animals in the 30R:70C treatment. There was a quadratic effect for the growth variables hindlimb height, forelimb height, body length, thoracic and barrel circumference over time, indicating that the animals presented adequate body growth, with intense development during the experimental period and stabilisation at the end of the experiment. There was no difference in the animals' weight gain, with an average daily gain of 182.79 g day-1. There was a difference in carcass characteristics throughout the evaluation period, with a larger loin eye area, body condition score and subcutaneous fat thickness at the end of the experimental period. The use of an extruded ration with a 30% roughage and 70% concentrate ratio promotes better feed efficiency in lambs, since it achieved the same weight gain and body development with lower dry matter intake.

“…The similar yield of meat cuts observed in all RIG groups reflects the similar SBW and carcass sizes of animals in different groups. Previous works provided evidence of moderate to high correlation among BW, carcass yield, and yield of meat cuts in sheep (Pinheiro and Jorge, 2010;Souza et al, 2014). According to Fernandes et al (2011), when animals of the same breed have equivalent body conformation, their carcass weight, carcass yield, and relative weight of meat cuts are also similar.…”

Residual intake and gain for the evaluation of performance, non-carcass components, and carcass characteristics of confined crossbred Texel lambs

We evaluated performance, non-carcass components, and carcass characteristics of crossbred Texel lambs in different categories of residual intake and gain (RIG). We assessed 77 crossbred (¼ Pantaneira and ¾ Texel) non-castrated animals in two study phases. The first phase included 47 lambs with an initial average weight of 29.9±5.5 kg, and the second phase included 30 lambs with initial average weight of 22.4±3.3 kg. Dry matter intake (DMI) and average daily gain (ADG) were evaluated for 70 days. Animals were divided into three groups in terms of efficiency: efficient (high RIG), intermediate (medium RIG), or inefficient (low RIG), based on the standard deviation of the mean for the RIG variable. We measured the yield of noncarcass components, carcass characteristics, and yield of meat cuts. Efficiency group had no association with DMI, nor with initial and final body weights of the animals. The ADG of efficient (0.310 kg day −1 ) and intermediate (0.290 kg day −1 ) animals was greater than observed in inefficient (0.260 kg day −1 ) animals. Lambs in the efficient and intermediate groups had significantly higher levels of all efficiency indicators evaluated. Efficient and intermediate animals yielded significantly more wool/skin in comparison with lambs in the inefficient group. Animals with high RIG also had lower relative weight of testicles/scrotal sac in comparison with inefficient animals. Fat deposition in the omentum and mesentery as well as total fat were decreased in efficient animals. No significant differences occurred among groups regarding carcass characteristics and yield of meat cuts. The RIG index allows for the identification of lambs with higher growth rates and greater wool/skin yield and lower proportion of visceral fat.
