Severe undernutrition in growing and adult animals

Abstract

1. Ten pigs which had been undernourished for a year, and weighed about 5.5 kg at that time, were rehabilitated on an excellent dict. They grew fast, but no faster per kg body-weight than normal pigs, and they stopped growing at the same chronological age. Consequently, they did not attain the same adult size as the normally reared pigs.2. The rehabilitated animals appeared to be fatter than the control animals, but the proportions of muscle to bone in the carcasses of the males and females were within the range to be expected in normal animals of the same fat-free weight, although the castrates may have been somewhat less muscular on this basis.3. The weights of the organs per kg of fat-free body weight were within the limits found in normally reared animals of the same fat-free weight.
