In vivo estimation of goat carcass composition and body fat partition by real-t...

The accuracy of ultrasound measurements to assess goat carcass composition and the partition of body fat depots was evaluated. An ultrasound machine with a 5-MHz probe and image analysis was used to assess in vivo fat thickness and muscle depth in 56 Spanish Celtiberica adult goats, in lumbar and breast body regions. The goats were slaughtered and the weight of body fat depots recorded. Measurements correspondi...

In vivo estimation of lamb carcass composition by real-time ultrasonography

The objective of this study was to evaluate the accuracy of ultrasonography to measure fat thickness in live lambs and predict carcass composition to find a system that can assess carcass composition easily and accurately, without damage to the product and can improve carcass classification. Fat thickness (FTh) between the 12th and 13th ribs and between the 3rd and 4th lumbar vertebrae, was measured in vivo us...

Utilização de ultra-sons na predição da composição de carcaças de caprinos e ov...

Com o propósito de efectuar uma análise sobre a utilização de ultra-sons na predição da composição de carcaças de caprinos e ovinos, foi realizada uma retrospectiva dos trabalhos efectuados ao longo dos últimos anos. Referiram-se os princípios do uso da técnica e metodologia de aplicação sendo abordados os aspectos relativos à experiência do operador, identificação de pontos anatómicos de medida, diferentes med...

Efeito do sexo, peso da carcaça e grau de maturidade nos tecidos da carcaça de ...

O objectivo deste trabalho foi estudar o efeito do sexo, do peso da carcaça e do grau de maturidade na proporção dos tecidos e em algumas medidas lineares da carcaça em cabritos de raça Serrana. Para o efeito foram utilizados 60 cabritos (31 machos e 29 fêmeas), com peso de carcaça compreendido entre os 4 e os 8 kg, o que correspondeu a grau de maturidade entre os 18 e os 44% para as fêmeas e entre 14 e 37% par...

In vivo ultrasonic measurements and live weight for predicting carcass quality ...

Forty six single male lambs of Churra Tensina mountain breed with a live weight ranging from 19.9 to 24.4 Kg producers of carcass type Temasco, were scanned by ultrasound (ALOKA model SSD-900, with a 7.5 MHz sounder) to determine M. Longissimus dorsi depth and subcutaneous fat thickness between the I Olh_l ]lh, 12th_13th dorsal vertebra and PI_2nd, 3rd_4lh lumbar vertebra. Lambs were slaughtered after 24 h. fas...

Efeito do sexo, peso de carcaça e grau de maturidade nas medidas e peças da car...

O objectivo deste trabalho foi estudar o efeito do sexo, do peso da carcaça e do grau de maturidade nas medidas de conformação e na proporção de peças da carcaça de cabritos Serranos. Para tal utilizaram-se 60 cabritos (31 machos e 29 fêmeas), com peso de carcaça compreendido entre 4 e 8 kg, o que correspondeu a 18 a 44% de maturidade para as fêmeas e 14 a 37% para os machos. Os cabritos foram abatidos após 24 ...

Subjective measurements of fat cover and kidney knob and channel fat for predic...

CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of leg and rib tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97% of the variation in muscle weight was accounted for by variation in CCW and the inclusion of KKCF amount scored from 1 to 9 improve the precision of the pr...

CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of shoulder, neck and flank plus breast tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97, 91 and 92% of the variation in muscle weight of shoulder, neck and flank plus breast, respectively were accounted for by variation...

The influence of sex and carcass weight on carcass composition of Serrana kids

Lamb meat quality of two breeds with protected origin designation. Influence of...

Lamb meat quality of two Portuguese products was examined. The influences of slaughter weight, sex and breed on eating quality were evaluated. Data were obtained from 72 lambs of two different breeds with protected designation origin. In accord with the normal slaughter weight in the region three classes were considered: A: 9–14 kg live weight; B: 14–19 kg live weight and C: 19– 24 kg live weight. pH of M. long...
