The Assessment and Recording of the Utilized Output of Grassland

During the years 1956 and 1957, an attempt was made to assess the output of Irish Pastures using methods proposed by a Sub‐Committee of the B.G.S. (9). It was found that the best results were obtained when output was determined on a single field, rather than on the whole farm basis. The yields showed highly significant correlations with both botanical composition and nutrient status of the pastures. The results were in agreement with the findings of others working on similar grasslands. It is suggested that the method might find a useful place in a programme either of advisory work or surveys concerned with grassland improvement.

Plots were sown broadcast with ryegrass, cocksfoot or timothy and were strip-grazed at various times during three successive winters by store cattle maintained almost entirely on foggage. In the first winter the plots were rested from 2 September. Each was sampled when required for grazing and the mean organic-matter yield was 2020 Ib. per acre containing 17-5% crude protein.In the two following years, when rested from 15 July and 10 August, November yields were 4340 Ib. (11-8% crude protein) and 3003 Ib. (16-0% crude protein), respectively. Ryegrass yields were 15-30% higher than timothy and 25-50% higher than cocksfoot. Losses during winter due to rotting were related to botanical characteristics and were 40% for ryegrass, 30% for timothy and 10-20% for cocksfoot. Cocksfoot was the most suitable for winter-grazing since it had the highest stockcarrying capacity at all times. This was due mainly to high consumption of ryegrass and timothy, not affecting live-weights, and increasingly poor utilization of the ryegrass produced. It is emphasized that grazing animals should be used when evaluating pastures. Foggage production is considered as a method of herbage conservation and in relation to whole-year pasture output.

Systems of calf grazing were compared in preliminary experiments during 1954 and 1955. Hereford colour-marked beef calves in the post-weaning stage were used, all calves having been reared on the nurse-cow system in loose boxes.The results indicate that autumn-and winter-bom calves can make good progress at pasture during their first summer, husk-free ground being one of the most important requirements in the production of well-grown calves.
