Extract

1. Perennial ryegrass (S. 23 and S. 24 sown together) and cocksfoot (S. 37 and S. 143 sown together) were compared in grazing and individual feeding experiments during the summer months of 1960, 1961 and 1962, using spring-born calves.

2. Herbage samples indicated that more grass was available to the animals grazing on ryegrass than on cocksfoot in 1961 but no differences were found in 1962. The ad lib. method of feeding should have ensured that quantity did not affect the results in the feeding experiments.
