Hyperproductivity of sows: what to do with extra piglets?

Every producer wants his business to be profitable, herefrom is a «race» for more liveborn piglets. On the one hand it is certainly bigger amount of meat kilograms sold. But on the other — a wide range of problems appear. During the VI International congress «Profitable pig production» Thomas Greve taught how to manage the multiple sows.

The main factor of sow’s is the amount of liveborn piglets. Nevertheless, it only needs to be accounted together with number of weaners (then the economic benefit is clear). Now better Danish farms have 39 piglets per sow per year. Sounds good! Thanks for multiple sows the farm produces more piglets, consequently sells more meat and has more money for it. But, to reach it it’s necessary to learn to overcome difficulties, associated with hyperproductivity.

First of all, the farm should be ready for work with hyperproductive sows and increasing capacities.

Secondly, the percent of mortality is bigger in the bigger litter and more piglets weight less than a kilogram. It’s naturally, because when sow born 17-18 piglets, they cannot weight 1.5-2 kg, physically. The weakest ones die during the first hours of life because of mistakes in management. Nurse sows help to avoid this problem (but their intensive usage often cause bigger percent of repairing) and increasing operator’s duties in farrowing unit.
