OBSERVATIONS ON USE OF PLASMA FREE FATTY ACID CONCENTRATIONS IN DETERMINATION OF MAINTENANCE REQUIREMENTS OF SHEEP

The objective of the investigations reported in this paper was to examine the possibility of using plasma free fatty acid concentrations as a means of estimating food requirements for maintenance purposes in sheep. Estimates derived in these investigations are considered to be less satisfactory than those based on live-weight change. It is concluded, however, that the technique merits further consideration, and that, with more precise knowledge of FFA concentrations in maintenance-fed sheep and of the FFA: food intake response curve, it could provide a useful alternative means of estimating maintenance requirements. © 1969, Cambridge University Press.
