Sixty pigs were used to study the effects of air movement (0.05, 0.5, and 1.0 m/s) at constant air temperatures of either 5.6 or 11.1°C above optimum, and at 3 different weight ranges (36–50kg, 54–68 kg, and 73–86 kg) during the growing-finish

SummaryIn trials with 64 pigs growing from 37 to 60 kg or from 65 to 88 kg growth rate and food conversion were not affected by either a 10°C or a 20°C range in diurnal air temperature cycle compared with a constant temperature equal to the mean of

SUMMARYVentilation rates of 0·14, 0·42 and 0·71 m3/min per pig (2·3, 6·9 and 11·5 air changes per hour) were compared at weight ranges from 42 to 65 kg and from 69 to 88 kg and at optimum ambient temperature and at 8°C above optimal. A total o

The effects of exercise on food intake, growth rate and behaviour were investigated in two trials with 32 pigs. The exercise took the form of running or walking four times the length of a concrete path twice a day. Food intake and rate of gain in bod

VENTILATION of cattle confine-ment buildings is restricted in cold weather for retention of animal heat as a means of warming the build-ing. A minimum ventilation rate of 0.43 m3/min per 455 kg animal (15 cu ft per min per 1000 lb) has been recommend
