Neste experimento foi investigado o efeito da restrição alimentar quantitativa sobre o desempenho e a qualidade da carcaça de suínos em terminação. A restrição alimentar, na razão de 7 % (T2), 14 % (T3) e 21 % (T4) do consumo à vontade (T1), diminuiu linearmente o ganho de peso diário e a espessura de toucinho, e aumentou linearmente a idade de abate (P < 0,05), enquanto o peso e o rendimento de carcaça foram afetados de forma quadrática e a percentagem de pernil na carcaça aumentou linearmente conforme se diminuía a quantidade de ração fornecida (P < 0,05). Abstract The effect of quantitative feed restriction upon the performance and carcass characteristics of the finished pigs was investigated. It was observed a linear reduction in the daily weight gain and backfat and linear increasing in the slaughtery age (P

Effect Of Age

Forty male lambs of the mountain Greek breed were used to evaluate the effect of age at slaughter on carcass characteristics and composition. The slaughter of lambs was carried out at the age of 30, 45, 60, 75 and 90 days. The slaughter procedure, carcass dissection and carcass composition were realized according to the standard method of CIHEAM-AGRIMED programme. The results of this work showed that the lambs of different age groups did not differ in dressing percentage significantly. The proportion of muscles showed a tendency of increase with the increasing slaughter age but the differences were not significant. The proportion of total fat in carcass increased with the increasing slaughter age from 20.84 to 23.59% for the age group of 30 and 90 days, respectively (P &lt; 0.05). On the contrary, as the age at slaughter increased, the proportion of bones decreased (P &lt; 0.05). Subcutaneous, intermuscular, perinephric and pelvic fats increased with the slaughter age, but only the subcutaneous fat was influenced significantly (P &lt; 0.05). Among the different commercial cuts proportions of long leg, first 5 ribs and shoulder decreased, while those of last 8 ribs-loin and breast-flank increased (P &lt; 0.05). The overall results suggest that the slaughter age of lambs of the mountain Greek breed should be increased from the present ~45 days to more advanced age of 75 or 90 days in order to improve the farmers&rsquo; profits without serious negative effects on the quality of carcasses or meat of lambs. &nbsp; &nbsp;

The growth and carcass characteristics of 627 crossbred lamb progeny from 20 Poll Dorset sires was studied. The sires were selected on the basis of Australian sheep breeding values (ASBVs) for postweaning growth (PWWT), depth of loin muscle (PEMD) and depth of subcutaneous fat (PFAT). Lambs were weaned either at 20- or 30-kg liveweight and then within each of these groups were maintained at their weaning weight for 55 days or fully fed, giving four treatment groups. Restricted lambs were realimented subsequent to the period of feed restriction and all lambs within each treatment group were slaughtered when their mean liveweight reached 45 kg. After adjusting for the weaning group and weaning age, liveweight at weaning depended on birthweight, rearing type and sex. For the late-weaning group, it also depended on whether the lamb was born as a single or a multiple and on sire ASBVs for PWWT and PEMD. This was such that liveweight increased by 0.14 ± 0.05 kg for each unit increase in sire ASBV for PWWT and decreased by 0.55 ± 0.20 kg for a unit increase in sire ASBV for PEMD. During the period of feed restriction, sire ASBV for PWWT had an effect on the growth rate of lambs in all treatments with a coefficient of 1.67 ± 0.52. Lamb growth rate during the realimentation phase increased with increasing ASBVs for PWWT at a rate estimated as 2.21 ± 0.49 g/day for each unit increase in PWWT. Early-weaned (20 kg), restricted lambs grew on average 26.0 ± 3.4 g/day faster during the refeeding period than the early-weaned, fully fed lambs, and for late-weaned lambs (30 kg) the difference was 35.5 ± 5.4 g/day. Lambs subjected to a restricted intake of pasture produced carcasses 0.79 ± 0.32 mm fatter on average than those fully fed as measured at the GR site (110 mm from the midline over the 12th rib). As the sire PFAT ASBV increased, the carcasses of the progeny were fatter at the GR site, fat C site (over the longissimus muscle at the 12th rib), the rump site (30-mm distal to the lumbar–sacral junction over the gluteus medius muscle) and in terms of carcass fat percentage. As the sire PEMD ASBV increased, progeny carcasses had larger loin muscle cross sectional areas, and as the sire PFAT ASBV increased, there was a decrease in loin cross sectional area. There was no impact of treatment group on lean percentage. As the sire PFAT ASBV increased, the carcasses contained less lean and as PEMD ASBV increased, the carcasses contained more lean equating to a potential 2% increase given the range of ASBVs in the experiment, which represents ~0.4 kg lean on average.
