Thin Sow Syndrome
The thin sow syndrome develops over a period of months and one or two pregnancy cycles, with gradual declining body condition until 10 to 30% of the animals have a condition score of 1 or 2. During lactation the sow is unable to maintain her body condition due to an insufficient intake of energy combined with increasing milk output. This process continues over successive lactations.
In sows kept permanently outdoors the stockman should ensure that all the sows have a high body score before the start of cold weather.
