“…Direct experimental evidence would be required on this point. This hypothesis is, however, compatible with a decreasing contribution of muscles to BW with age in bovines and ovines [70,71], and with a higher contribution of muscles to total energy expenditure and total protein synthesis in young versus mature animals [72,73].…”

-The objectives of the present paper were to review and quantitatively determine the influence of the nutritional factors on whole body glucose turnover in growing and adult non-productive ruminants. A meta-analysis approach was used. The dietary grain: forage ratio significantly increased the slope of the relationship between glucose turnover and metabolisable energy intake. This effect was probably associated with the inclusion of maize rather than any other grain source in the diet. The analysis pointed out the possible differences in response between growing and adult non-productive animals, and suggested that the performance level of the animals (and their glucose requirements) could contribute to regulating whole body glucose turnover. This aspect would warrant further investigation.whole-body glucose turnover / meta-analysis / ovines / bovines

“…By comparison, energy expenditure of muscles (35-50% body weight) represent only 8 to 16% of total energy expenditure of the whole animal, while adipose tissues and skin represent 10% and up to 18% each (in vivo data by Harris et al, 1989; Lobley, 1990 and Symonds and Lomax, 1990, as well as conclusions from a modelling exercise by Gill ef al, 1989). Other estimates for the whole carcass, which includes muscles, adipose tissues, skin and bones, are slightly higher at 45-60% .…”

“…Consequently, the contribution of each tissue or organ to the protein synthesis of the whole body can be determined. It should be remembered that the quantity of protein synthesised in the organism each day is between two-and four-fold the protein intake (Lobley, 1990).…”
