A pig farm with 3000 sows in Songxi
County, Nanping City, Fujian Province
In order to help solve problems encountered in the breeding process of farmers and improve the efficiency of farming, Puai Group invited Hans Bundgaard to this pig farm in Songxi County, Nanping City, Fujian Province on 9th November, 2017. Currently, this farm has 3000 sows in stock and intends to expand in the future. During the visit, Hans Bundgaard has made suggestions for problems that existing in the farm.
A: In the first five days after weaning, increasing the feed amount for sows, for example, from 2.5 to 4-4.5 kg is beneficial to the ovulation. In this way, the number of litters will be increased.
B: Measuring the backfat thickness at point P2 is a good way to measure maximum production performance. The backfat of gilts should not be less than 12mm before breeding. Before the delivery, the backfat thickness of sows need to reach 18-20mm, because they may lose 3-4mm backfat during the lactation.
C: Adding extra light in the pig houses, at least 200 lux, 16 hours per day, which will increase the litter size.
A: Increasing the phosphorus content in the gilt feed. In addition, sprinkling 50g of calcium hydrogen phosphate three times a week on the floor.
B: Increasing 10-15% of vitamins and microelement in the gilt feed, so that sows can have good bones. If it can't be solved by adding in the feed, consider throwing vitamins and microelement on the floor to feed them.
C: For the gilt with the limp, it can be used for 8 days with Tiamulin. If it is infected by mycoplasma, Tulathromycin injection can be a solution.
A: Usually, the birth weight of piglets should be 1.3 kg. If majority of piglets’ weight are way lighter than this, it would be a good solution to increase the feed quantity four weeks before farrowing.
B: when a sow gives birth to so many piglets, it is very important for the sow to have high milk production. This means the formula of pregnant or lactation feed must be designed according to the recommended standard. Hans Bundgaard recommends that the farm leader should refer to the Danish pig nutrition recommendation, which will greatly to help reduce mortality and increase milk production.
C: The foster care for piglets can be done earlier. Also, check the number of effective nipples before the sow delivery, which can determine how many piglets that this sow can take care of. You can take out the bigger ones in redundant piglets in the litter after sow delivering, and foster them to a sow that has been delivered for one week. One-week-old piglets are fostered to a 21-day-old weaned sow, which is a two-step foster care method. Selective foster care must be processed quickly, because the weaker piglets will soon fall behind of the sows and then become even weaker and difficult to recover.
D: It is suggested that piglets with diarrhea symptoms for 3-4 days can be fed with 1ml of Toltrazuril or similar products to solve the problem of coccidiosis diarrhea.
During the visit, Hans Bundgaard emphasized that any small problem in the process of raising a pig is a big one. Because any small problem may lead to the decline of the overall efficiency of the pig farm. Hans Bundgaard believes that even the smallest problem must be taken seriously and rigorously, so the overall efficiency of pig farms can be improved. Hans Bundgaard also mentioned many times that the production performance of this pig farm is already very good. If the existing problems can be solved one by one, the benefits of the pig farm can be further increased.
