Abstract

A recent study is described consisting of a substantial new programme of work with sheep and linked to one with dairy cows and complementary to that which formed the basis for the development of equations to calculate feed ME contents from chemical analysis, which is briefly outlined. A summary of the equations from both studies is tabulated. Results indicate a need for more information about the ME value in sheep as compared with cows, of feeds containing high concentrations of sugarbeet and citrus pulp with high concentration of added fat and further studies on interaction effects of forage quality on the determined ME content of supplementary compound feeds.
