Nutrition and gestation Management When designing a feeding program for ges- tating sows, remember overall goals for the nutri- tion program: 1) prepare to be in proper body sows condition at farrowing; 2) maximize reproductive performance (farrowing rate and litter size); and 3) meet the daily nutrient requirements at the lowest Possible cost (measured as cost per sow per day). Problems with gestating sows overfeeding Không cần include expense, potencial problems with impaired mammary development, and re- duced feed intake in lactation. Over-conditioned sows to be the main problem used on many swine farms, but in recent years, thin sows have trở a little more prevalent problem.Too body tissue Reserves can Reduce reproductive performance and tăng sow mortality. Reserves Low cũng backfat can be an animal welfare concern thin vì sows have a greater chance of Developing shoulder Sores. The success of a limit-feeding program de- pends on controlling the intake of each gilt or sow. Care taken to see có Phải each female gets Her daily allocation. Individual sow feeding stalls are an effective device for controlling boss sows. If sows are fed group, it is imperative có beige feed spread across a large area to Reduce fighting and Ensure all animals consume có có feed allot- ment. In the group housing systems, many managers sẽ tăng the feed allowance per sow rõ by 10 to 15% to account for wastage and boss sows Consuming more feed allowance ask for their coal. How shouldnt be quyết sow feeding levels khi gestation? Most agree on the Importance of having sows in the farrowing at correct body condition.

The next biggest component of the gestation requirement is the amount of feed or back-weight fat bạn want the sow to gain. If you feed sows the maintenance level, chúng Will Maintain body weight, but lose backfat.
