US Jinbao Animal Nutrition Corporation, DSM, Purina jointly launched a sow year-old production of milk Pig Psy30 head plan, aimed at improving the number of piggy pigs in the mother pig, becoming a pig A main tool for improving the reproductive performance of sows.
For any business, the longer employee work, the greater the contribution to the organization. Creating profits require time, pig industry is also the same. Usually the sow needs to experience 3-4 fetuses to achieve peak of production capacity. In view of this, the average fetal time of successful sow should be more than 5 tires. Only the number of sow sows in each child can obtain profits.
Industry experts have recently gathered in this topic together, and incorporating 30 heads of pigs in the mother pig. Teams include: Dr. Brenda de Rodas (Dr. Pigs, Pigan, Pig, Zach, Dr. Zach Rambo (Jinbao Pig Research Nutrition), Dr. Jon Bergstrom (DSM Advanced Technical Support Manager). Three nutritionists describe the life of sow and its importance from three main aspects, the causes, potential problems, management and nutrition, are considered effective in successfulness and profits of sow.
Step 1: Detection Industry Status
The first step in detects the current situation, master the reference value, and compare the gap between its ideal value. When the two are compared, the researchers have seen improved space. For example, PIC’s goal specifies that the sow should reach 5.5 tires, but PIC production data shows that its best level is an average 4.5 tires. Similarly PIC recommends that the downs of the sow should be as low as 44%, but most farms have been higher than 45%.
Keeping the sow has reached 5-6 tires to help improve farm profits because of strengthening the fetal structure. Maintaining a voluntary elimination rate is less than 30%, which increases the average number of 5-6 fetal pigs. This level is reached, combined with the input of the young and healthy back, producers can achieve the average fetal sow with a 3.5-child sow and create more profits.
The best profitable fetal structure should maintain the balance of the sow in each age, Dr. De Rodas said. Focus on the sows in all ages, we need to consider the balance of the number of female pigs: representing the new genes of the new gene, 3-4 hot sows can consider the elimination of old sows.
Dr. Bergstrom agrees that the average fetal timing of the sow should be 3.5 tires, and it is pointed out that the current level of the industry does not reach this target value. Even 25% US first-class pig field sow average fetal second, Dr. Bergstrom said. Most pig farms are lower than this level, and many sows have not reached high-yield period, which has been eliminated.
We have studied a lot of low-premium sows, and the farmers have lost their large part of them when they are young, and Dr. Bergstrom said. When we eliminated the mother pig and the low sow, we found that they did not reach the annual production of 30 heads of pigs, even in their lives did not achieve this.
Step 2: Analyze potential problems
After mastering the actual and ideal level gap, the nutritions analyzes the reasons for sow elimination. They will eliminate mother pigs into two categories: voluntary (proactive) and non-voluntary (passive).
Voluntary elimination standard is a low-quality performance caused by age or age, eliminating these sows optimizes the sow structure, and Dr. Rambo said. On the other hand, non-voluntary elimination means that these sows must perform phase-out, such as breeding failure, lame. These sows may have good breeding potential.

US National Animal Health Monitoring Service (NAHMS) data shows that the non-voluntary elimination rate of sows exceeds 50% (26.3% of the reproducia, 15.2% of the lame, 4.0% damage, other 4.9% ), Only 13% of the sow is eliminated by production performance, and the sow eliminated by age factors is less than 40%.
It is recognized that the lame is a primary reason for the sow ‘s unmunivative elimination, and the researchers have made further research on this. A survey of the Midwest of the United States expressed 19% of the reserve sows before childbirth, the reserve sow was eliminated due to lame problems during the first child.
That is to say, when the mother pig group enters the second child, the number of others will be due to lame problems.Dr. Rambo pointed out.
If we can guarantee these backup sows and young sow health, we will have the opportunity to eliminate sows based on age or production performance, he added. This will have more choices when eliminating sows, or improve the production performance of the entire sow.
Step 3: Finding solutions
The three nutritioners agree with nutrients to improve the life of the sow and achieve a significant role in the balance of sow. With the growth of the mother pig, its nutritional demand has changed.

In the 2267 sow, the rear sow (first tire) always represents low feeding. The shortage of the birth of the head pork is particularly serious because they are still growing, and the stock of the head of the fetal mother pigs is very small. De Rodas pointed out. The study also showed that the third and fourth fetal mother pigs were the highest in the amount of food, and the pigs in the sows in 7 tires were reduced.
This amount of feeding that declines with age, means that the high tire sow may not have nutrients needed, unless the diet formula is adjusted. When adjusting a single proportion, the team recommends the anime, vitamin and mineral intake of the average daily feeding capacity, vitamins and minerals.
Average daily feeding capacity
In the study, the proportion of the Purina sow increased the average annual feeding capacity of the breastfeeding sauce by 0.54 pounds. Other similar experiments also show that adding Purina mother pigs reduces the non-production of the sow by 34%. Vitamins and minerals
Dr. Bergstrom pointed out that high fetal sows were limited to energy in pregnancy. When these sows eat less, in order to maintain steady state in the body, theyVitamins and miners consumed by the metabolism weight will also be reduced. This will lead to insufficient nutrients consumed by maintaining optimum health and growth performance. DSM pointed out that PIC data shows that the intake of the third child, the 5th fetal mother sow, the intake of minerals is reduced by 27%, 43%, respectively.
According to the fetal adjustment of the day grain form, the focus is in improving the feeding capacity of lactation, and the age, weight, and the design of the best day grain, mineral, minerals, so that the sow can be extended Life, Bergstrom pointed out. In accordance with individuals, you need to feed, increase the life of the sow and maintain the balance of the fetal structure.
