FAULTY sow feeding causes chronic (extended days to conception and low litter size) and acute (anoestrus and early culling) reproductive failure. The fact that feeding errors are so frequently the cause of poor breeding herd performance is a cause for concern; not least, because they are avoidable. In nine out of 10 cases, sow feeding problems are not those of vitamins, minerals, or even of protein, but of quantity of feed given.
