Piglets go back to the same teat, says free-range pig farmer

Sows lounge in the sun as their piglets play, while others feed their litters in the privacy of their own cozy shelter at Hamish and Angela Cottle's free range pig farm near Timaru.At Hamish and Angela Cottle's free-range pig farm, some sows lounge in the sun as their piglets play while others feed their litters in the privacy of their own cosy huts.When Country Life comes to visit Highground, there are no barns, crates or concrete floors to be seen - just fresh air, sunlight, and lush, open fields. Listen to the storyAs Cosmo Kentish-Barnes checks out the huts, or farrow houses in action, Hamish explains the batch farrowing system, where he aims for 35-odd sows to birth (farrow) at the same time."If you think about a pig, they're an amazing animal, really."Unlike cows or sheep, which have relatively low reproductive rates, Hamish explains that a piglet can give birth to over two litters a year and up to 12 piglets."If you're looking at 2.2 litters a year, she can give you 25 to 26 piglets a year. That's a pretty amazing, productive animal."One striking difference at the Cottle's farm is their commitment to free-range practices.Farrowing paddocks are designed to provide each sow with her own individual hut for giving birth, and once the piglets are ready, they have the freedom to roam and explore outdoors."They get into little gangs and they might run away across the other side of the paddock and they'll see you coming and run back to Mum," Hamish says.He's always amazed by how the piglets have an innate sense of which hut is theirs.In contrast to some indoor pig farming practices, where sows may be confined to pens, the sows here have ample space and natural surroundings. The farrow houses at the Cottle's farm are based on a 1950s design known as the "rotor round farrowing house."Internally, there's a designated piglet safety zone that ensures the well-being of the young ones.To adapt the farm to their free-range philosophy, the Cottles have made modifications to these structures transportable.Helping out with the care of the piglets is Ben Lester, who says pigs are quite different to other animals he's worked with on various farms."They're quite unique characters and individuals - sheep and cattle tend to follow."While Ben's love for working with pigs is evident, he admits the job can become challenging when dealing with a pig mother who's feeling threatened…Go to this episode on rnz.co.nz for more details
