[more ▼] 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.

[more ▼] 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.
