Dossier "Ambiance" : Maîtrise de la ventilation + Le refroidissement évaporatif : cooling et brumisation en porcherie

Dossier composé de deux dépliants Maîtrise de la ventilation Rappel des règles à suivre pour un bon fonctionnement de la ventilation. Inventaire des observations, influences des conditions météorologiques et du…

Benefits of fuzzy logic in pig house atmosphere control

Actually, the regulators dedicated to pig-house atmosphere follow the same principle. Their working is in fact essentially based on a temperature set-point and on a temperature range. However, a statistical…

Partial recycling of ambient air in a piggery

Two ventilation systems were studied in two identical piggeries equipped with total slatted floors. Data were collected on pig growth performance and health status as well as on the quality…

Effects of evaporative cooling on pig house ambience and on fattening pig growth performance

Evaporative cooling produced on average a decrease in ambient temperature of 2.5°C when the exterior temperature was above 25°C. The maximum difference between the control room and the cooled room…

Effect of the humidity level of ambient air (temperature 28°C) on the growth performance of growing-finishing pigs

An experiment was carried out on 144 cross-bred growing-finishing pigs to determine the effect of ambient air relative humidity levels on growth performance and on animal health. Three relative humidity…

Incidence du taux d'humidité relatice de l'air ambiant sur les performances zootechniques du porc à l'engrais élevé à 28°C

Une expérience portant sur 144 porcs charcutiers de type croisé a été effectuée afin de déterminer l’influence du niveau d’humidité relative de l’air sur les performances et l’état de santé…

Influence of ambient temperature and feed intake level on growth performance of growingfinishing pigs

An experiment using 360 growing-finishing pigs was conducted to determine the effect of ambient temperature (24 vs 17 °C) and the level of feeding on the pig growth performance. Pigs…

Influence of increasing temperature and live weight on the feeding behaviour of group-housed growing pigs

The individual feeding behaviour of group-housed Piétrain x Large White barrows was studied in groups of 3 to 4 pigs over two stages of growth (S1 and S2), corresponding to…

Behaviour of new-born piglets related to thermoregulation

Observations were made using 5 litters of piglets during a period of 24 h after birth. The farrowing pens consisted of sow crates on a slatted floor, cast iron slats…

Influence of high temperatures on performance and feeding behaviour of lactating sows

Twenty-four multiparous Large White sows were used to investigate the effects of ambient temperature (T) and dietary protein content (CP) on lactating performance. Sows were allocated to two main thermic…

Oilseeds for weaned piglets : rapeseed, sunflower seeds and extruded full fat soybeans

Four isoenergetic and isonitrogenous diets were compared in three successive trials. Each trial used 360 weaned piglets.Each diet had the same oil content (3 %) provided by : 3 %…
