“…Results higher than those were reported by Ryan et al (2007) for crossbred Boer goats fed diets with different levels of concentrate (50, 70, and 90 g/100 g) and with an average hot carcass weight of 14.07 kg. They found the leg yield to be between 26.89 and 31.05 g/100 g, and the shoulder to be between 23.01 and 25.82 g/100 g. The genetic composition and the diet of the goats utilized by these researchers is likely the explanation for these differences.…”

-The effect of the substitution of Tifton hay (0, 33, 66, 100 g/100 g) for pineapple (Ananas comosus L.) stubble hay was evaluated in the characteristics of the carcasses of goats of an unknown breed (UB) in feedlot. Thirty-two bucks with an average initial live weight of 17.5±1.3 kg, at approximately 150 days of age, were housed in individual stalls provided with feeding and drinking troughs. The animals were distributed in a completely randomized design with four treatments and eight replications. There was a quadratic effect on the weights of hot carcass and cold carcass, empty body, and loin eye area. A linear increase was observed for losses by carcass cooling. The weights of commercial cuts and the weights of total muscle, total bone, intramuscular fat, and total fat decreased linearly. All morphometric measurements were influenced by the inclusion of pineapple stubble hay in the diets. Substitution of Tifton hay for pineapple stubble hay at the level of 33 g/100 g improves the carcasses of UB goats qualitatively and quantitatively.

“…Johnson et al (1995), Dhanda, Taylor and Murray (1999) and Ryan et al (2007) found averages of 6.0; 4.3 and 5.8 kgf.cm -2 , respectively. In the literature, great variations are found in the results from different authors, and they can be attributed to differences in nutrition, age, cooking time and temperature, and final pH.…”

“…Ripoll et al (2012) described that it is possible to distinguish between lambs reared on concentrate or alfalfa by its fat colour, since carotenoids are present in forage but less so in concentrate diets. Similarly, Ryan et al (2007) found that diet could affect to muscle colour, with animals from concentrate diets having higher redness and yellowness of the longissimus muscle. Nonetheless, beyond the interactions and differences found in kidney fat colour, because our animals were very young, fat colour was white in all breeds and it implies that it would be well accepted by consumers (Carrasco et al, 2008).…”

This experiment aimed to describe the influence of production system on the following characteristics from seven Spanish goat breeds: carcass weight, dressing percentage, head weight, viscera weight, kidney fat weight, fatness score, carcass length, leg length, rump perimeter, rump width, kidney fat colour and tissue composition of shoulder. Experiment involved 201 male, single-birth suckling kids from five meat and two dairy breeds. Animals from meat breeds were slaughtered at two targets carcass weights (light, 4 kg; heavy, 7 kg). In dairy breeds, half of the animals were reared with dam's milk and the other half with a milk replacer and all of them were slaughtered at light weight (4 kg). Statistics consisted in two GLM, means for each variable, a PCA to study relationships between variables and a discriminant analysis to compare breeds. In dairy breeds, breed had greater influence than milk diet, with breed effect being particularly strong for kids that were fed with natural milk. In meat breeds, slaughter weight was more important than breed and many significant interactions were found between both effects. All carcass traits were closely related to each other and to slaughter weight. Slaughter weight was also positively related to dressing percentage and to fatness degree. Discriminant analysis explained 76.1% of variability and separated dairy breeds, with well-fattened, medium-shaped carcasses, from meat breeds, with good conformations and medium fatness degrees. Hence, carcass traits were able to group breeds by diary or meat type.Additional key words: carcass tissue composition; fat colour; goat; morphometric measurements. Resumen Influencia de la raza, tipo de lactancia y peso al sacrificio sobre las características de las canales de cabritos lechales de siete razas españolasEl experimento describe la influencia del sistema de producción sobre las siguientes características de la canal de cabritos de siete razas españolas: peso de canal, de la cabeza, de las vísceras y de la grasa renal, rendimiento a la canal, engrasamiento, longitud de la canal y de la pierna, perímetro y anchura de la pierna, color de la grasa renal y composición tisular de la espalda. Se utilizaron 201 cabritos machos, de parto simple, de cinco razas cárnicas y dos lecheras. Los animales de las razas cárnicas se sacrificaron a dos pesos de canal objetivo (ligeros, 4 kg; pesados, 7 kg). En las razas lecheras, la mitad de los cabritos se alimentaron con leche materna y la otra mitad, con un lacto-reemplazante y todos los animales fueron sacrificados al peso ligero (4 kg). En las razas lecheras, la raza fue más importante que el tipo de lactancia, especialmente en los cabritos alimentados con leche natural. En las razas cárnicas, el peso tuvo mayor influencia que la raza, aunque se observaron numerosas interacciones entre ambos efectos. Todas las variables estuvieron estrechamente relacionadas entre sí y con el peso al sacrificio y éste ultimo estuvo además positivamente
