Paper 2 · Livestock Production
In selecting a sow for breeding, which characteristic matters most to the number of piglets she can rear?
Athe height of the sow measured at her shoulder
Bthe depth of the back fat measured at her shoulder
Cthe colour of the bristles running along her back
Dthe number of sound, evenly spaced teats she carries
Explanation: Every piglet needs a working teat of its own, so the teat count sets the ceiling on how big a litter the sow can actually raise. Back fat and height affect her condition, not her suckling capacity.
