	abstract = {The red deer genotypes currently being farmed in New Zealand have different forage-use habits and exhibit different growth
profiles in different seasons. Three genotypes (NZ red, eastern European and elk-cross) were subjected to low and high nutritional
regimens during autumn, winter and spring. Few differences among genotypes were found in autumn, but in winter the elk-cross
genotype grew faster than did the NZ red and eastern European genotypes. NZ red deer consumed approximately 9\% of their
diet as hay in both autumn and winter, while eastern European and elk-cross deer had much higher intakes of hay (up to 44\%).
Divergence in response to the high- or low-nutrition regimens imposed developed in winter. Liveweight gain averaged 84 g/d on
the low nutrition regimen and ranged from 132 to 199 g/d for NZ red and elk-cross genotypes respectively on the high-nutrition
regimen. Eastern European deer were immediate. In spring as the NZ red genotype did not respond to increasing feed availability,
while the eastern European and elk-cross deer increased growth rate by approximately 50 g/d and 100 g/d, respectively, in response
to increased feed availability. This was matched by increases in forage and metabolisable energy intake. Understanding these
interactions provides information that will enable feeding systems to be tailored to deer genotype to improve on-farm resource-use
efficiency.
