	abstract = {Currently less than 20\% of the lambs slaughtered in New Zealand  each year for export are killed in the five months from July to  November. The feeding of high grain content diets in feedlots, grain  supplements at pasture, maize silage or forage legumes to increase lamb  supply over this period is discussed. Grain-based feedlot diets,  supplements of pea grain fed at pasture and lupin and tick bean forage  produced lamb liveweight gains of 200 to 300 g/d, that compare with  gains of up to 150 g/d expected at pasture. Effects on carcass leanness  and meat taste were generally small. Although usually more expensive  than pasture, other feeds can be at least as profitable when pasture is  in short supply premiums are paid for lambs supplied in winter and  spring.  },

	abstract = {The efficiency of winter feed use for weaner calf production was  compared in a yearling heifer mating system compared to a 2 year old  first mating system in traditional and dairy x beef cows. These  computer modelling analyses illustrated, with yearling heifer mating  compared to 2 year old first mating, that the total weight of calf  weaned per unit of winter feed required is increased by only 2\% (Angus  dams) and 6\% (Hereford x Friesian dams, HxF). With HxF dams compared to  Angus dams, the total weight of calf weaned per unit of winter feed  required was increased by 8\% (2 year old first mating) and 13\% (yearling  heifer mating).   Yearling heifer mating rather than 2 year old first mating within a  traditional beef cow breed is questioned, when compared at the same  winter feed requirement. The superiority of dairy x beef breeding cows  on the basis of calf production from winter feed is confirmed by this  analysis.  Furthermore, this superiority is maximum when yearling  heifer mating is also adopted.  },
