The growth of muscle, bone, fat and connective tissue in cattle from 150 days' gestation to 84 days old

摘要: The growth of muscle, bone, fat and connective tissue was investigated in 30 half-sib Friesian foetuses calves over five age phases from 150 days' gestation to 84 days old. Large changes the coefficients all four carcass tissues most 'standard muscle groups' pre-natal confirmed this as a period intense differential growth. Changes bone showed that post-natal patterns these differed greatly their were generally established by birth. Most large impetus nine observed period, some further occurring up 28 post-natally. There no significant groups two beyond days. High standard errors associated with depots total dissected fat, reflecting variation depot fatness among animals similar age. Problems dissection fatty made it difficult interpret A functional basis is postulated for within musculature.
