N.  aSeasonal variations in the feed and water intake of normal sheep.h[electronic resource]  c1960  aAbstract: For 18 months 9 adult sheep were given to appetite a diet of a concentrate mixture and pakar tree leaves, Ficus infectoria [Ficus virens]. Water was given 3 times daily and the animals were muzzled while exercising. In summer, with higher temperatures, water intake was higher than in all other seasons, 3.9 kg per day compared with a mean of 3.1 kg. Insensible loss also was most in summer, 2.6 kg per day; in spring it was 2.2, in autumn 1.6 and in winter 1.3 kg. Relative humidity was lower in spring, and was the cause of the difference between spring and autumn. Both air temperature and relative humidity affected water metabolism. Daily intake of dry matter (DM) was greatest in winter and least in summer, 0.995 and 0.872 kg, and digestibilities were 52.29 and 50.21%. Intake and digestibility of protein, fat, carbohydrate, N, Ca and P were least in summer. The ratios of intake of water to intakes of total and digestible DM were widest in summer, 4.5 and 9.0, respectively, and closest in autumn and winter, 3.1 and 5.8, respectively. They reflected both the increase in intake of water and the decrease in intake of DM in summer. It is recommended that good quality roughages should form the main feed offered in summer since more leaves and less concentrates were chosen then. J. G.
