FROM THE first association of man and beast, grass of one type or another has played a very important part in the feeding of farm animals. Over the past twelve to fourteen years, all-grass wintering has been carried out with some success, but during the past four to five years the Ministry of Agriculture and Fisheries has launched a very comprehensive programme of instruction in this form of wintering. In more recent years, Grasslands Division, DSIR, has developed some excellent grasses that are durable under heavy stocking and of high protein value.
