“…In any case, these results are contrary to the trend shown for each of males, castrates and females, by Davies et al (1980) where the fastergrowing pigs had the higher muscle:bone ratio. Elsley et al (1964), Goenaga & Carden (1978) and Walstra (1980) found negligible differences in muscle:bone ratio with differences in growth rate due to nutrition.…”

SUMMARYSelected data of McMeekan (1940, 1941) were reanalysed to compare the proportions and distribution of tissues, and the weights of some organs, in pigs growing at different growth rates due to differing levels of nutrition. The effects of variation in fat content were excluded, and the distribution of tissues was compared at the same total weight for each tissue, by allometric regressions. Except for components of the head and neck, and the stomach, the results do not support a concept of retardation of development by poor nutrition of those parts of the body with the highest relative growth rates.

Thirty-five female Large White pigs were weaned at 14 days of age, penned individually, given a single diet and slaughtered serially at 25,40,55 and 70 days of age. A control group was fed to appetite throughout while three groups were subjected to feed restriction at various ages postweaning. For the periods 25 to 40,40 to 55,55 to 70 days of age pigs fed to appetite gained 321 (?19.9), 532 (k35.4) and 603 (k35.5) g liveweight day-'. Pigs restricted between 25 and 55 days, followed by refeeding from 55 to 70 days, gained 192 (k14.0), 169 (k44.8) and 508 (k81.0) g liveweight day-'; pigs restricted between 40 and 55 days, followed by refeeding from 55 to 70 days, gained 425 (?42.8), 409 (k49.6) and 480 (k70.1) g liveweight day-'. A group given 200 g feed day-' gained 42 (t4.2) g liveweight daily between 25 and 70 days. Refed groups did not differ significantly from controls in their feed intakes for the period 55 to 70 days, either in absolute intakes or in feed intake kg-' mean liveweight. Refed pigs grew no faster, and made no greater protein gains than controls of equivalent weight; however, lipid gains were elevated.

An anatomical study compared the effects of sex and a twofold nutritional difference in growth rate between 20 and 100 kg live weight, on 63 entire males, castrated male and female Large White x Landrace pigs. While the effect of growth rate was significant for overall fat deposition in the carcasses of all three sexes, it was greatest for the entire male. In contrast, sex and nutritional effects on the distribution of fat and on the proportion and distribution of muscle and bone were small.
