This study compared the technological quality of twelve muscles of llama that were raised in a grazing system. The llamas (n=10) were slaughtered using Bolivian standard procedures. Carcasses were stored for 24 h in a cold room (4 ºC). Muscles were removed from the left side of each carcass in the slaughter house. Five steaks (2.54 cm thick) were cut from each muscle. In each muscle was determined pH, holding capacity (WHC) and Warner-Bratzler shear-force (WBSF). No statistical difference was found in pH between muscles. Values of L* (lightness) and b* (tenor of yellow) in L. thoracis, L. lumborum and Semimembranosus were higher than those in Triceps brachii and Psoas major (p<0.05). The cooking loss percentage was lower in Infraspinatus and Longissimus thoracis (p<0.05). The WBSF value in the Semimembranosus, Semitendinosus, Quadriceps femoris and Biceps femoris muscles was highe...

Se comparó el contenido de grasa y perfil de ácidos grasos de carne de ovino y caballo finalizados bajo pastoreo. Los ovinos (n=10) y caballos (n=10) fueron faenados bajo procedimientos estándares de Chile. Las canales fueron refrigeradas durante 24 horas a 4 ºC. Los análisis fueron realizados en el músculo Longissimus lumborum (LL). La carne de ovino presentó mayor contenido de grasa intramuscular y mayores niveles de ácidos grasos saturados, pero más bajos niveles de ácidos grasos poliinsaturados en comparación a la carne de caballo (p<0.05). En la relación ácidos grasos poliinsaturados/saturados y el contenido de ácido linoleico conjugado, la carne de ovino presentó valores inferiores a los encontrados para carne de caballo; sin embargo, la carne de ovino mostró la relación n-6/n-3 (2.60) dentro de los niveles recomendados y adecuados niveles de ácidos grasos dese...

This study compared the proximate composition and fatty acids profile of llamas slaughtered in two seasons. Twenty 18-24 month old llamas reared in native pastures were used, of which 10 were slaughtered in the dry season and 10 in the rainy season under standard procedures. Carcasses were stored for 24 h in a cold room (4 to 6 ºC). Samples of the Longissimus lumborum muscle were collected and moisture, crude protein, lipids and ashes were analysed. Llama meat slaughtered in the rainy season had higher intramuscular fat content (p<0.10) and higher levels of monounsaturated and polyunsaturated fatty acids (p<0.05), but lower levels of saturated fatty acids (p<0.05) as compared to llama meat slaughtered in the dry season. The ratio polyunsaturated/saturated fatty acid ratio and linoleic conjugated content was higher in llama meat of the rainy season. However, meat of both seasons...

Llama meat has a high protein level and low cholesterol and lipid levels. The aminoacids profile is similar to other ruminants. The fatty acid profile is characterized by moderatelevels of saturated fatty acids and high levels of monounsaturated fatty acids and lowlevels of polyunsaturated fatty acids. The carcass of animals from 36 to 44 months of age is the most suitable for commercial cuts, while meat from older animals, based on theirtechnological characteristics, is more suitable for the manufacture of meat products.Carcasses of young llamas are characterized by low weight, poor conformation and littlefat cover. Feed supplementation in young animals helps improve carcass quality andperformance of commercial cuts, as well as meat quality.

This study compared the chemical composition and instrumental meat quality of bovine, llama and horse from animals finished under grazing systems. The bovines (n=31), llamas (n=21) and horses (n=27) were slaughtered using Chilean standard procedures. Carcasses were stored for 24 h in a cold room (4 ºC). The Longissimus lumborum muscle (LL) was collected for determining the chemical composition, cholesterol, collagen content, pH, colour (L*, a*, b*, H*, C*), water holding capacity (WHC) and Warner–Bratzler shear-force (WBSF). Llama meat had higher levels of protein and total collagen (p<0.05), and lower level of fat and cholesterol (p<0.05) than bovine and horse meat. No statistical differences were found in moisture and ash percentages between species. The L* (lightness) and b* (yellowness) values of llama LL were higher (p<0.05) than those in the bovine and horse, while the ...

Se comparó la composición química y calidad instrumental de carne de bovino, llama, y caballo finalizados bajo pastoreo. Los bovinos (n=31), llamas (n=21) y caballos (n=27) fueron faenados bajo procedimientos estándares de Chile. Las canales fueron refrigeradas durante 24 horas a 4 ºC. En el músculo Longissimus lumborum (LL) se determinó la composición proximal, contenido de colesterol y colágeno, pH, color (L*, a*, b*, H*, C*), capacidad de retención de agua (WHC), pérdida de cocción, pérdida del descongelado y fuerza de corte Warner-Bratzler (WBSF). La carne de llama presentó mayores niveles de proteína y colágenos totales (p<0.05) y menor concentración de grasa y colesterol (p<0.05) en comparación a la carne de bovino y caballo. No se observaron diferencias estadísticas en porcentajes de humedad y cenizas entre las tres especies. Los valores de L* (luminosidad...

This study compared the fat content and fatty acid profile of sheep and horse finished under grazing systems. The sheep (n=10) and horses (n=10) were slaughtered using Chilean standard procedures. Carcasses were stored for 24 h in a cold room (4 ºC). Analyses were carried out on the Longissimus lumborum muscle. Sheep meat had higher content of intramuscular fat and higher levels of saturated fatty acids, but lower levels of polyunsaturated fatty acids compared to horse meat (p<0.05). In the polyunsaturated to saturated fatty acid ratio and linoleic conjug content, sheep meat presented values lower than those founded for horse meat. However, sheep meat showed an n-6/n-3 (2.60) ratio within the recommended levels and good levels of desirable fatty acids (67.76%).

Se comparó la composición proximal y perfil de ácidos grasos de carne de llamas faenadas en dos estaciones del año. Se utilizaron 20 llamas de 18 a 24 meses de edad criadas sobre pasturas nativas. Diez animales fueron faenados en la estación seca y 10 en la estación lluviosa bajo procedimientos estándar. Las canales fueron refrigeradas durante 24 h a 4-6 ºC. Se tomaron muestras del músculo Longissimus lumborum (LL) para análisis de humedad, proteína bruta, grasas y cenizas. La carne faenada en la estación lluviosa presentó mayor contenido de grasa intramuscular (p<0.10) y mayores niveles de ácidos grasos monoinsaturados y poliinsaturados (p<0.05), pero niveles más bajos de ácidos grasos saturados (p<0.05) en comparación a la carne de llamas faenadas en la estación seca. La relación ácidos grasos poliinsaturados/saturados y el contenido de ácido linoleico con...

La carne de llama presenta un alto nivel proteico, perfil de aminoácidos similar a otros rumiantes, bajo nivel de colesterol y lípidos. El perfil de ácidos grasos se caracteriza por moderados niveles de ácidos grasos saturados y altos niveles de ácidos grasos monoinsaturados, pero bajos niveles de ácidos grasos poliinsaturados. La canal de animales de 36 a 44 meses es la más indicada para obtener cortes especiales, mientras que la carne de los animales de más edad, basado en sus características tecnológicas, es más adecuada para la fabricación de productos elaborados. Las canales de llamas jóvenes se caracterizan por tener bajo peso, pobre conformación y poca cobertura grasa. La suplementación alimenticia de animales jóvenes permite mejorar la calidad de la canal y el rendimiento de los cortes nobles, así como también la calidad de carne.
