“…Segundo Hogg et al (1992), a perna, o lombo e a costeleta posterior são os cortes de maior valor comercial e representam 50,9% da carcaça de caprinos Saanen machos castrados com 1 a 5 anos de idade. Os resultados deste experimento foram semelhantes se considerada a perna, o lombo e o corte da 6 a a 13 a costelas nos animais de todos os tratamentos e que foram abatidos com 5,5 meses de idade.…”

“…Os resultados deste experimento foram semelhantes se considerada a perna, o lombo e o corte da 6 a a 13 a costelas nos animais de todos os tratamentos e que foram abatidos com 5,5 meses de idade. Os valores obtidos para paleta diferiram dos reportados por Hogg et al (1992) e podem ser atribuídos ao fato de que esses autores incluíram uma parte do pescoço no corte.…”

“…A composição tecidual neste experimento foi semelhante à observada por Hogg et al (1992) para caprinos machos castrados abatidos com 15,8 kg de carcaça (em média, 71,5; 17,3 e 10,2% para músculo, osso e gordura, re spectivamente, como composição tecidual média da perna, sem diferenças em relação à composição apresentada pelas fêmeas), o que reforça o conceito da semelhança da composição entre fêmeas e machos castrados.…”

RESUMO -Com o objetivo de estudar o efeito da restrição alimentar sobre as características da carcaça de caprinos leiteiros, realizou-se um experimento utilizando 27 cabritos castrados da raça Saanen. Os animais (PV inicial de 20 kg) foram distribuídos nos tratamentos alimentação à vontade e 30 e 60% de restrição, sendo abatidos aos 35 kg de PV. Foram avaliados o rendimento comercial e biológico, os cortes comerciais, a área de olho-de-lombo e a composição tecidual da perna. O rendimento biológico não foi afetado pela restrição alimentar, mas o comercial diminuiu com o aumento da restrição. A elevação no nível de restrição alimentar promoveu diminuição do lombo e da 6 a a 13 a costelas e aumento da paleta e do pescoço, proporcionalmente à meia-carcaça. A proporção de ossos aumentou e a de gordura total diminuiu com o aumento da restrição. O tecido muscular não foi afetado pela restrição. A restrição alimentar de até 30% não prejudicou a qualidade da carcaça de caprinos leiteiros.Palavras-chave: cabritos castrados, composiçao tecidual, gordura, músculo, rendimento comercial Feed restriction in goats: carcass yield, commercial cuts, and carcass composition ABSTRACT -Twenty-seven Saanen male kids averaging 20 kg of body weight (BW) at the beginning of the trial were used to study the effects of feed restriction on carcass characteristics. Animals were assigned to one of the following three treatments: control (fed ad libitum), 30 or 60% of feed restriction. A completely randomized design was used and data were submitted to regression analysis; animals were slaughtered when they reached 35 kg of BW. The following traits were measured in this trial: carcass commercial and biological yields, commercial cuts, tissue composition of hind leg, rib eye area (REA), and carcass compactness. Increasing feed restriction reduced carcass and commercial cut weights as well as loin and fat proportions in the carcass. Conversely, proportions of bone, neck, and shoulder clod all increased when the feed restriction went from 0 to 60%. Muscle tissue proportion was not changed by feed restriction in this study. It can be concluded that 30% of feed restriction did not negatively affected carcass quality of Saanen dairy kids.Key Words: castrated kids, commercial yield, fat, muscle, tissue composition Introdução A criação de caprinos para produção de leite no Brasil tem apresentado melhoras consideráveis, com significativos aumentos da média diária produzida, obtidos com melhoramento genético, manejo e nutrição adequados. Esses resultados têm motivado o incremento da produção leiteira em algumas regiões do país, observando-se, porém, poucas melhoras no aproveitamento dos cabritos para produção de carne.Em decorrência da elevada prolificidade da espécie caprina, o número de cabritos nascidos em um rebanho leiteiro ao longo do ano representa um grande potencial para produção de carne, o qual habitualmente não é utilizado pelos produtores, que realizam o sacrifício dos machos ao nascimento. O sacrifício dos cabritos constitui uma forma de el...

Eighty-nine intact male, castrates and female South African indigenous goats in three age groups (0, 2 -6 and 8 permanent incisors) and two pre-slaughter conditioning groups; namely, the non-conditioned which were slaughtered within three months of purchase and the pre-slaughter conditioned, which were slaughtered 6 -10 months after purchase or birth were used. The effect of sex, age and pre-slaughter conditioning on live animal, carcass dimensions and carcass composition were evaluated. The goats were large with live weight, carcass weight and carcass dimensions in the range of the large breeds of southern Africa. They had a high lean and low fat content. Intact males were suited for high chevon yield because they were heavy, had a high lean and low fat content, and losses during dressing and chilling were reduced by improved nutrition. Goats between 2 -6 teeth yielded heavy carcasses that were comparable to goats in the 8-teeth group, and had proportionately more lean and less carcass fat. The hind limb was ideal for high lean and low fat, high value cuts but the dorsal trunk was bony and yielded less lean. Pre-slaughter conditioning improved the overall size of the goats and reduced the losses during slaughter and chilling. It also improved the lean/bone and lean and fat/bone indices. _______________________________________________________________________________________

“…Although there were no statistical differences in WBSF due to sex, Hogg et al (1992) and Johnson et al (1995) found that WBSF values for female goats were significantly lower than castrated or intact male goats. The low fasted body weight (FBW) observed in the current study (Table 1) may have prevented significant differences between the sexes.…”

The effect of three management systems on meat quality of 61 goat kids was determined. Kids from the extensive management system displayed stronger ''pink'' meats than animals from intensive systems with natural and artificial rearing management. The type of management system did not affect the pH, chemical composition and sensorial evaluation. Intensive combined with artificial rearing management system meat displayed the lowest capacity to retain water inside the muscle. Intramuscular fat deposits from kids reared under extensive management system showed the lowest percentage of C14:0 fatty acids and the highest percentage of C18:1 fatty acid. A strong influence of physical activity and trough grazing modulated the fatty acid profile in muscle of kids reared under an extensive management system, producing healthier meat relative to intensive with natural and artificial rearing management systems, as reflected by the fact that the lowest atherogenicity index was measured in intramuscular fat from kids reared under extensive management system. An extensive management system produces similar goat kid meat as intensive with natural and artificial rearing management systems, but with a lower atherogenicity index.
