“…Experiments with whole milk (Owen, Plum and Harris, 1965;Khouri, 1969) and with milk substitutes (Burt, 1968;Ackerman, Thomas, Thayne and Butcher, 1969) have shown little difference in the performance of calves given limited quantities of these diets either once or twice daily. The advantages of once-daily feeding are the reduction in labour costs and the convenience of feeding at a particular time which does not clash with periods of peak labour requirements such as milking time.…”
