To achieve targets, you must exercise good breeding management. Proper heat detection and hand mating are two important tasks to help you achieve maximum use of farrowing crates, and to reach targets. If nursing sows are weaned in good body condition, they will come back into heat quicker. Then you can rebreed them on schedule. Start heat detection within two days after weaning.
Some sows come into heat very quickly.
If you wait until four days after weaning you, will miss some. Mate a sow at 24 hour intervals as long as she will stand. Provide a clean, dry mating area to encourage good copulation. To achieve good profitability in the sow barn, keep the farrowing crates full, set targets and try to meet them. Time and effort spent in breeding management will give you good returns in the farrowing part of your operation and in overall profitability.
