“…In this study, no difference was found in the CL of the carcasses of either studied species (Table 2), and despite the reduced amount of subcutaneous fat observed in the carcasses, the obtained values are within the mean range cited in the literature for goats 1.90 to 2.17%, (OLIVEIRA et al, 2008); 2.0 to 5.3%, (SOUSA et al, 2009) and sheep 3.0 to 3.5%, (LANDIM et al, 2007); 2.04 to 3.06%, (CARTAXO et al, 2011).…”

This study was conducted to evaluate the in vivo and carcass characteristics of goats and sheep sold for slaughter, which originated from different regions of Ceará State, Brazil. Thirty-six (36) mixed-breed, uncastrated male animals (18 goats and 18 sheep), acquired from street markets, which were raised in an extensive production system from the regions of Quixadá, Sobral, and Tauá, were used in this experiment. Before slaughter, the animals were weighed, and body measurements were taken and the body condition score was assessed. Post-slaughter, the carcasses were weighed, morphometric measurements were obtained, and the commercial cuts were weighed and their yields were calculated. The mean in vivo body weight was 23.83 ± 3.76 kg for the goats and 25.22 ± 5.25 kg for the sheep; the body condition score was close to 2, and the mean age was 12 months, with no differences between the species. No differences were found between species and origin for the weights and yields of carcass or for chilling loss. The carcass conformation values were considered poor, and the fat cover was classified as too lean, with the goat carcasses considered superior to the sheep carcasses in these respects. The sheep had higher values for loin-eye area, subcutaneous fat thickness, and weight and proportion of leg than the goats. Mixed-breed goats and sheep reared in extensive systems in Ceará State and sold in street markets in the capital, irrespective of their origin, reach their slaughter weight at an advanced age and with a lean body condition, resulting in carcasses of a low quality, with a low muscle content and poor fat cover. In the extensive conditions of the state of Ceará, animals of the ovine species have a greater ability for meat production than caprine species.

“…This information corroborates with the results of this study in which WLBC values varied from 2.59 to 3.23 %, evidencing that the similarity (P≥0.05) observed was a reflection of the similarity with EGS. Cartaxo et al (2011), when evaluating the effect of inclusion from 2.40 to 2.90 Mcal/kg in the diet of lambs, found lower WLBC when EGS was higher.…”

The aim of this study was to evaluate the effect of substitution of Cynodon hay with banana plantation residue hay on the carcass characteristics and tissue composition of commercial cuts of feedlot Santa Inês lambs. Twenty-five whole lambs were used, with an average age of five months and an initial live weight of 26.95 kg (± 1.5), distributed in a completely randomized design with five treatments (1 = 40% Cynodon spp. hay + 60% concentrate; 2 = 20% banana leaf hay + 20% Cynodon spp. hay + 60% concentrate; 3 = 40% banana leaf hay + 60% concentrate; 4 = 20% banana pseudostem hay + 20% Cynodon spp. hay + 60% concentrate; 5 = 40% banana pseudostem hay + 60% concentrate) and five repetitions. The lambs were slaughtered on day 69 of the experiment. The variables evaluated were: live weight without fasting (LWWF), live weight post-fasting (LWPF), morphometric measurements in vivo and postmortem, hot and cold carcass weights (HCW, CCW), hot and cold carcass yield (HCY, CCY), biological performance and weight loss by chilling. The carcasses were divided into eight commercial cuts: neck, shoulder, foreshank and hindshank, breast and flank, loin, leg and rack. The leg, shoulder and loin were dissected into muscle, fat and bone. The animals fed on pseudostem hay showed higher LWWF, LWPF, body length, HCW and CCW; however, the HCY, CCY, morphometric measurements and commercial cut weights and yields were not altered by the treatments. The use of pseudostem hay allows for heavier carcasses; however, the use of coproducts changed the characteristics and carcass yield of the assessed commercial cuts. cinco meses, peso vivo inicial de 26,95 kg (± 1,5), distribuídos em delineamento inteiramente casualizado com cinco tratamentos (1= 40% de feno Cynodon spp. + 60% concentrado, 2= 20% de feno de folha de bananeira e 20% de feno de Cynodon spp. + 60% concentrado, 3= 40% de feno de folha de bananeira + 60% concentrado, 4= 20% de feno de pseudocaule de bananeira e 20% de feno de Cynodon spp. + 60% concentrado, 5= 40% de feno de pseudocaule de bananeira + 60% concentrado) e cinco repetições. Os cordeiros foram abatidos aos 69 dias de experimentação. As variáveis avaliadas foram: peso vivo sem jejum (PVSJ), peso vivo com jejum (PVCJ), medidas morfométricas in vivo e da carcaça, peso da carcaça quente e fria (PCQ, PCF), rendimento da carcaça quente e fria (RCQ, RCF), rendimento biológico e perda por resfriamento. As carcaças foram divididas em oito cortes comerciais, sendo o pernil, paleta e lombos dissecados em músculo, gordura e osso. Os animais alimentados com feno de pseudocaule apresentaram maior PVSJ, PVCJ, comprimento corporal, PCQ, PCF, entretanto, o RCQ, RCF, medidas morfométricas da carcaça, pesos e rendimentos dos cortes comerciais não foram alterados pelos tratamentos. O uso do feno de pseudocaule permite a obtenção de carcaças mais pesadas, entretanto, os coprodutos alteram as características e rendimento da carcaça e dos cortes comerciais avaliados.

“…This can be attributed to the form of rating these two traits. While the degree of finishing is evaluated visually by the amount and distribution of fat throughout the carcass, the FT is measured in a specific location on the carcass, which in this case may be responsible for having an advantage over the visual assessment, since Santa Inês lambs have been associated to carcasses with lower fat (Cartaxo et al, 2011) unlike the Brazilian Somali breed (Fernandes Júnior, 2010).…”

, and for the carcass compactness index (CCI) it was 0.17±0.01kg/cm, 0.17±0.01kg/cm, 0.11±0.01kg/cm and 0.16±0,01kg/cm, for SI, SB, MN and F1, respectively. There were no significant differences between SI, BS and F1 regarding REA and CCI. Although, in general, the MN presented a relatively lower performance than the other genotypes, this breed had similar carcass yields and fat thickness when compared to SI and F1 and similar conformation and REA in comparison to the BS. Regarding meat quality, no differences were observed between genotypes, except for redness and cooking losses. It is concluded that no one group had a higher or lower performance in all traits analyzed. Moreover, for the management conditions employed in this study, there was evidence of greater specialization in meat production for genotypes SI, BS and F1 when compared to MN, although there are no substantial differences between the four groups regarding meat quality.
