Eight diets, their metabolisable energy (ME) concentrations ranging from 2.3 Mcal/kg to 3.6 Mcal/kg (9.6 to 14.1 MJ/kg) were fed to each of four pens of broilers in two trials. Food intake was inversely related to energy concentration but the ME required by each sex to reach a given live-weight was quite similar. Birds on the diets with a medium energy concentration (about 3.1 Mcal/kg (13.0MJ/ kg)) required slightly less ME than those on other diets and generally reached the required live-weight earlier than those on other diets. Birds in the first trial required less of any particular diet than their counterparts in the second trial, reflecting the lower ambient temperatures recorded during the latter trial. Mortality recorded from 14 d of each trial was generally lower for birds on the medium energy concentration diets and dressed carcass percentage higher than those on other diets.The results of the present study are in agreement with the recent recommendation (National Research Council, 1971) of 3.2 Mcal ME/kg (13.4 MJ/kg) for broiler diets. However, it is suggested that minimum and maximum values be given in such recommendations; this would allow greater flexibility and a wider range of ingredients in diet formulation.

If activity net revenue distributions for farm planning under risk are subjectively assessed, the claimed advantages of MOT AD (Minimisation Of Total Absolute Deviation) programming can be reaped only if some way can be found of generating discrete vectors of net revenue deviations. Pseudo-random sampling is evaluated for this purpose and it is shown that, even with relatively large sample sizes, there is an appreciable risk that the MOTAD formulation will yield solutions some distance from the (E, V)-efficient frontier. An alternative procedure is described based on the use of linear programming to define a discrete distribution of outcomes that has means, variances and co-variances similar to those of the elicited joint normal distribution. It is shown that a MOTAD formulation based on a discrete distribution so derived can closely approximate the (E, V) frontier.
