Abstract

In 3 experiments, groups of 5 Merino rams were individually fed a pelleted ration at maintenance (1 kg/day), with or without 750 g/day of lupin grain, and kept indoors under conditions of natural light and temperature. Measurements of scrotal circumference and liveweight were made during winter, spring-summer and autumn, for periods of 42–49 days. Ambient temperatures and daylengths were recorded. The season of the experiment affected the rate of change of scrotal circumference. Rams fed the maintenance diet showed a pattern of increasing scrotal circumference, starting in late spring after the spring equinox and reaching a maximum in autumn-early winter, then decreasing in mid-late winter after the winter equinox. Scrota1 circumference responded to increased nutrition under all daylength regimes and the magnitude of this response was influenced by the season.
