The time spent under a shelter by 8 grazing fattening bulls of the Belgian Blue breed was recorded during 35 days using a time-lapse recorder with IR illumination. The observation period was divided into 166 hours with rain (20 %) and 674 hours without precipitation (80 %). An occupation rate was calculated for each hour as the sum of the time spent under the shelter by each of the 8 bulls divided by 480 (8 animals x 60 minutes). The average occupation rates were 15.4 +/- 29.1 % for the hours with rain and 4.5 +/- 14.8 % for the hours without precipitation (P<0.001). The occupation rate was significantly influenced by intensity and duration of the rain : the occupation rate being higher during rainfall than with dry weather when the intensity of the rain was at least 0.4 l/m2 and the duration more than 2 hours. There was no significant difference between the live weight gain of the animals with a shelter and of other bulls grazing on an adjacent pasture without shelter. Our observations suggested however that a shelter may improve the welfare of the animals. [less ▲]

A study was undertaken to provide practical information concerning the frequency of temp. and RH measurements required to obtain a good estimate of their averages and of their daily variations, and to determine the relationships between ammonia, carbon dioxide and bacterial concn in a pig house. Measurements were made in 9 artificially ventilated farrowing or weaner houses with slatted floors. Temp. and RH were measured every 20 min for 7 d. Sensors were placed inside buildings in the middle of the houses, 0.8 m above floor level, and outside the buildings. Data were recorded using a datalogger. Ammonia and carbon dioxide concn were measured using 8 h Gastec diffusion tubes. Three readings were taken in the same location at 2-day intervals. The airborne bacterial concn was measured with a 6-stage Andersen sampler. Bacteria colony forming particles (BCFP) were collected by impacting onto agar-filled petri dishes which are placed in an incubator for 24 h prior to counting the colonies formed. Results are discussed, indicating no significant correlation between the 3 measures of pollution (NH3 and CO2 concn, BCFP levels) despite careful microclimate control. [less ▲]

Water requirements are determined according to the amounts of water stored in the tissues and lost by the animal. This review summarises estimates of water losses by faeces, urine, milk and by evaporation from the skin and respiratory tract. A description of the main pig drinkers is given with recommendations about the number, siting, fixing height and flow rate. Drinking water quality guidelines are also given. [less ▲]
