Wool production of sheep fed weekly different amounts of roughages of two protein concentrations.
TL;DRAbstract
For each breed, when groups were offered more or less than energy requirements for maintenance, sheep fed the 18.3 per cent crude protein diet grew more wool than sheep fed the 8.0 per cent crude protein diet at a similar energy level. This difference was not observed in some groups until the following three weeks when maintenance energy levels were fed. For each breed, during the following seven weeks when weight remained relatively constant, there was generally no difference in the rate of wool growth between groups fed the different protein diets. The results indicate that similar nutritional parameters regulate wool growth of sheep maintaining weight, whether offered diets weekly or more frequently.
