“…This factor also pointed out that C WL is the single factor which most compromises the economic index, since losses due to cooling interfere with the carcass weight and quality, and consequently reduce its price. For (Landim et al, 2017;, an alternative to increase C WL is the use of the Rabo Largo breed in terminal crossbreeding.…”

The objective of this study was to characterize the meat production potential of Morada Nova lambs from different genetic groups using morphological and zoometric data, performance and carcass characteristics. A total of 24 non-castrated male lambs from two genetic groups were used: Morada Nova red (MNR) and Morada Nova F1 red x Morada Nova white (MNF1) breed, with an initial mean body weight of 16.9 ± 3.43 kg and an average age of four months were distributed in a completely randomized design. Evaluations of morphometric data and zoom indices, performance and carcass characteristics were measured and calculated. Univariate and multivariate techniques were used to differentiate and reduce the number of variables, to group them and then develop and validate a sheep meat production index. Only 12 differences in the 29 morphometric measurements and zoometric indices analyzed were observed (P < 0.05). Furthermore, only 7 of the 28 quantitative and qualitative characteristics of the carcass were greater (P < 0.05) in MNF1 lambs. The yields of commercial cuts and the physical-chemical characteristics and qualitative measurements of the carcass were similar (P > 0.05) between the genetic groups. All groups of variables, except the cut yield, have discriminatory power (P < 0.05) with the highest classification percentages for body morphometry (91.3%) and zoometric indices (95.7%). The four identified factors, which together explain more than 85.0% of the total data variation, were renamed in the following order of importance: morpho-economic (38.5%), morpho-productive (18.8%), morpho-commercial (17.5%), and equilibrium (11.0%). The heat map showed the suitability in the morpho-commercial and morpho-economic factors for MNF1 lambs, while the MNR lambs showed emphasis for the equilibrium factor. Thus, the Sheep Meat Morphometric Index (SMMI) resulted in the following equation SMMI =\(\frac{\text{A}\text{I} \times 0.771 + \text{C}\text{H} \times 0.759 + \text{R}\text{H} \times 0.878 + \text{T}\text{P}\text{R}\text{I} \times 0.876 + \text{B}\text{I} \times 0.550 + \text{C}\text{W} \times 0.905}{100}\) In which: AI is the anamorphosis index; CH is chest height; RH is rump height; TPRI is the thoracic perimeter relation index; BI is body index; and CW is chest width. The application and validation of the developed index showed superiority (P < 0.001) for meat production in the crossed lambs. MNR and MNF1 lambs have high thoracic development, compact character and aptitude for meat production. Lambs crossed between genetic groups of the MN breed are another sustainable option for sheep production in drylands. It is recommended that the SMMI be used as a tool for morpho-productive selection criteria in breeding programs in the MN breed, as well as other small native breeds.

“…La homogeneidad en relación con las proporciones de los cortes tal vez se debe a las características morfométricas similares relatadas entre corderos de cruces DO-SI y SI (48), aunque difieren de los obtenidos en otra investigación, donde fueron verificados mayor porcentaje de paleta en corderos SI en relación a cruces DO-SI (22). Mayor porcentaje de paleta sugiere que el animal tuvo mayor desplazamiento en busca de alimentos para satisfacer su requerimiento nutricional diario (49).…”

Canal y carne de corderos Santa Inés y cruces con Dorper o Texel: Un meta-análisis

et al. 2020

Objetivo. Evaluar las características cuantitativas de la canal y composición química de la carne de corderos puros Santa Inés (SI) y cruces con Dorper (DO-SI) o Texel (TX-SI), terminados en confinamiento, mediante un meta-análisis. Materiales y métodos. Bases de datos virtuales como Google Scholar, Science Direct y Scielo fueron utilizados para seleccionar los artículos cientifícos publicados desde el año 2000 a 2019. Palabras clave como genotipo, corderos, características de la canal y calidad de la carne, tanto en idioma español, portugués e inglés fueron utilizadas como criterios de inclusión de los artículos. De cada grupo genétipo, fueron evaluados: desempeño animal, características cuantitativas de la canal, cortes de la canal y composición química de la carne. Todos fueron incluidos en el análisis proveniente de 36 artículos científicos. Resultados. Peso corporal final, peso de la canal caliente, rendimiento de la canal fría y porcentaje de músculo no difieren entre los diferentes genotipos evaluados. Corderos DO-SI presentaron mayor consumo de materia seca, ganancia diario de peso, área de ojo de lomo y porcentaje de lomo. Composición química no fue influenciada por los genotipos. Conclusiones. En ambiente tropical y subtropical, corderos puros SI terminados en confinamiento presentan características cuantitativas de la canal y composición química similar a los corderos de cruces DO-SI y TX-SI.

“…Oesophagostomum venulosum e Trichuris ovis (RAMOS et al, 2004;MENEZES et al, 2011;DOMINGUES et al, 2013). Haemonchus contortus, é considerado o mais patogênico a ovinos, sendo encontrado predominantemente no abomaso e acometendo todas as categorias de animais, porém, os animais mais jovens são os mais vulneráveis (LANDIM, 2017). Esse parasito é responsável pelas maiores perdas econômicas, principalmente, em áreas temperadas e tropicais.…”
