Pasture Profit index to be outlined at Beef 2014

The Grassland Village is set to be a must visit at Teagasc Beef 2014 next week, among he highlights in the area will be Teagasc’c new Pasture Profit Index.

The Profit based index(€/ha), for perennial ryegrass cultivars in Ireland has been developed recently by Teagasc in conjunction with the Department of Agriculture, Food and the Marine (DAFM).

The purpose of the index is to assist grassland farmers to identify the best perennial ryegrass cultivar(s) for their farm. The Pasture Profit Index comprises of 6-sub-indices: spring, mid-season and autumn grass Dry Matter (DM) production, grass quality (April to July, inclusive), 1st and 2nd cut silage DM production and persistency.

The economic merit of a cultivar for each trait was calculated by determining the difference between its performance and the base value for that trait, and this was then multiplied by the economic value for that trait using the Teagasc Moorepark Dairy Systems Model.

The economic value of an extra kilogram of grass DM in spring and autumn was higher than mid-season because it supported an extended grazing season. The performance values included in the Pasture Profit Index are based on data collected from the DAFM grass evaluation trials. Pasture Profit Index ranges from €226/ha to €8/ha per year for 16 cultivars on the current DAFM recommended list, however as more data becomes available the index will be assigned more recommended listed grass varieties. The index can only be assigned to varieties that have data generated from DAFM’s grass variety evaluation protocol.
