The nature and variability of the carcass characters of Danish and English bacon pigs

Abstract: 1. The quality status of Danish and English Wiltshire bacon sides representative of the highest grades produced at the present time has been investigated by the use of carcass measurements. The data resulting provide “standards” for practical guidance in stock improvement work on bacon pigs, and for the evaluation of experimental treatments involving bacon quality.2. The variability of the respective characters has been compared by means of the coefficient of variation of each. The results indicate that while … Show more

“…Thus Lush et al (1930) have shown that width measurements of the pelvis, hooks and pinbones, as well as chest depth and body length, are markedly slowed down in growth during the winter period of feed scarcity, while such early maturing measurements as height at withers, and hips and measurements of the head do not show any very certain indication of an abnormal retardation of growth during these periods. Similarly, McMeekan (1940McMeekan ( , 1941 showed that the weight of the early developing head in his High-High group of pigs was 205 % of the weight of the Low-Low group, while that of the lumbar region amounted to 405% of the weight of the Low-Low group.…”

“…McMeekan & Hammond (1939) observed that their fast-growing pigs had a low proportion of head and legs compared with slow-growing pigs, and it might have been expected therefore that the faster-growing group II pigs would have had shorter legs than the slower-growing group I pigs. Eeference to Table II will show that the reverse was the case, group II pigs being distinctly leggier in type.…”

“…In experiments of a somewhat similar nature With pigs, however, McMeekan & Hammond (1939) observed that extreme differences in plane of nutrition did affect the proportions of bone, muscle and fat in the resulting carcasses. Compared with the treatments which were necessary to produce them, the differences obtained may not appear very great, but from the point of view of carcass quality, they were most important.…”
