Thus, they will be well developed, in both size and weight, in the autumn and can proceed directly to finishing. The earliest born (late January to late February) are well suited to many systems of bull beef production because they will be well grown before turnout to pasture and can have a long first grazing season.
These matings result in the production of approximately 300,000 Holstein-Friesian male calves. Currently, approximately sixty per cent of the 1.0 million dairy cows are mated to Holstein-Friesian sires (to produce replacement heifers). The breed mix used on the dairy herd is summarised in another paper at this conference (Beef production from the Dairy Herd). Once bulls are ready for sale any delay or price discounting relative to steers can greatly reduce margins. Clarity is also needed on acceptable carcass weight and fat cover. Irrespective of production system, it is imperative that a market outlet, and the approximate sale price, be established from the outset. The economics of production is, to a large extent dependent upon calf purchase price and concentrate costs. red veal, cereal beef, conventional rearing followed by silage/ concentrate finishing and conventional rearing followed by high concentrate finishing. There are many systems of bull beef production, e.g. However, rearing males as bulls has inherent efficiencies due mainly to their higher production potential arising from the natural presence of the male hormone testosterone. Before decoupling of support premia, bull beef production was generally less profitable than well managed steer beef, partly because of the higher premium earning capacity of the steers.
Finding the most suitable beef production systems for these male dairy calves is a challenge for the industry resulting in a renewed interest in bull beef production as an option for these calves. Initially, at least, these extra male calves will be predominantly Holstein/Friesian (and some other dairy crossbreds). With the forecasted expansion of Irish dairy cow number 3, following the proposed changes of the milk quota regime, there will be greater number of dairy type claves available for beef production.
