Farmer holding a piglet

丹麦 Thorupgaard 农场猪群繁殖案例研究

背景介绍 2006年,丹麦产猪2570多万头,是世界最大的猪肉生产国和出口国 之一(85%的猪肉用于出口,占丹麦出口总值的5.3%)。 丹麦的家庭农场众多,猪的繁殖业更是发达, 约有7800家养猪 场。 Espen Dollerup先生所拥有的家庭农场Thorupgaard位于北日德兰郡 (North Jutland)的法瑟(Farsø),该地区气候温和、温度适宜:夏天凉 爽(平均温度16 °C),冬天无严寒(平均温度0.5 °C)

Modern pig farming is highly specialized with frequent splits between where the pigs are bred and where the pigs are reared. The Thorupgaard farm is specialized in breeding sows, with the offspring of the sows being reared on other farms. The production unit on the farm consist of 3 distinct but connected buildings. The sows are moved from one building to another depending on their stage of gestation. Having the buildings connected makes this process very easy. During the whole reproductive cycle it is crucial to keep the environmental parameters of the various structures under tight control. This allows for maximum breeding efficiency of the sows.

热气和湿气积聚

Each ventilation system is dimensioned to supply both minimum and maximum ventilation. Minimum ventilation is the volume of air that needs to be supplied to the animals for maintaining a proper air quality, which means prevention of heat and moisture build-up, removal of carbon dioxide, ammonia, odours and dust. All of these parameters can influence the animal’s performance negatively if left uncontrolled. Maximum ventilation is the quantity of air that needs to be passed through the building to remove any excess heat produced by the animals.
