dig-igm-es-10261-213122018-09-04T11:24:44Z Seasonal variation in voluntary food intake in growing lambs Mantecón, Ángel R. Iason, G. R. Hunter, E. A. Seasonality Voluntary Food Intake Lambs 3 pages, 1 figure, 1 table. In both sheep and deer, a seasonal depression in voluntary food intake (VFI) has been observed, such that the nadir of the annual cycle occurs in winter (Kay, 1979). This possibly represents an adaptation among some temperate and high latitude species to a predictable seasonal decline in food availability or quality (Kay and Staines, 1981). The annual cycle of VFI is thought to be entrained by photoperiod and one study has shown a difference between two breeds of sheep in its amplitude (Kay, 1979). This decline in VFI may be accompanied by a concomitant depression in fasting metabolic rate in winter (Blaxter and Boyne,1982). The estimation of feed requirements of sheep on similar diets is normally considered to be a function of live weight or metabolic body weight. If different genotypes have different propensities for a depression in VFI in winter, then this should also be considered as a determinant of their requirement for nutrients. This study describes and compares the pattern of VFI in winter by growing lambs of six different British hill and upland genotypes.
