Abstract
Extract
In this talk I shall be dealing with two quite distinct groups of people who find common ground in some 40,000,000 humble animals—the sheep and cattle populations of New Zealand. You, as practising veterinarians form the first group, and your prime concern is the health (or, if you prefer it, the diseases) of these two species. The second is composed of what, for want of a better term, I shall call pasture workers, and it is concerned, directly or indirectly, with the provision of feed for those same domestic animals. The name is chosen because, under New Zealand conditions, “feed” and “pasture herbage” are virtually synonymous terms.
