BONE GROWTH AND DEVELOPMENT WITH PARTICULAR REFERENCE TO BREED DIFFERENCES IN CARCASS SHAPE AND LEAN TO BONE RATIO

摘要: Two topics related to bone growth and development are considered: 1) Breed differences in weight distribution, 2) The inter-relationships of carcass shape, lean ratio characteristics between breeds. 1) Evidence on distribution is reviewed the results an analysis using MLC dissection files reported. This was based 753 steer carcasses from 17 breed-type x feeding system groups complementary with analyses published recently fat distribution. Small little commercial importance were recorded groups, a finding which agrees existing evidence. 2) Breed variation conformation its relationship examined data above more recent breed comparison trials at Ingliston Sutton Bonington. Results indicate that, although there definite trend for breeds better have higher ratios constant subcutaneous percentage, certain crosses do not relate well this trend. The discussed relation genetic history various breeds.
