4 weeks batch production system: another choice for small pig farms – Yangshuo – China Animal Husbandry Website – A useful animal husbandry website


Batch management is an important way of modern scale pig farm management. The boss of the pig farm now has generally realized the importance of batch management, and I also want to give my own pig farm. Batch management. What kind of pig farm is suitable for batch management? This is a problem that plagues a lot of pig farms. Previously, the author said that there were more than three weeks. Today, the four-week batch production system in the small pig farm and the three-week batch production were compared. For all reference.
Comparison of the surrounding batch production (4WBF) and three-week batch production (3WBF)

In today’s European pig industry, small farm (up to 500 production sow ) It is very common to use a childbirth system for more than 1 week. The advantages of these batch delivery systems include better arrangement of pig farms, as well as health and transportation advantages due to larger weaning batch, longer interval, and more age. The most common management in Spain is 3 weeks batch delivery, with average lactation for about 28 days, but there are several different types of childbirth products.
This article discusses 4 weeks batch delivery (4WBF), which is common in small pig farms (250 sows) including some countries, including France. The analysis will be based on the 3 weeks batch delivery (3WBF)
The production of lactation is required for 28 days of lactation, while 4 weeks is only 21 days. Obviously this is an important change, which advantages and disadvantages need to be evaluated before making a decision.
Batch size
The production of only 5 children in 4 weeks, 2 batches were less than 3 weeks, so the quantity of each batch was large. For example, a pig farm in a stock of 250 sows in a 4 weeks batch production system, each batch will have approximately 50 birthday production, and 36 batch production systems have approximately 36 (tire) production. 4 and 3 weeks batch subsequent age differences between 4 weeks and 3 weeks respectively. 4 weeks batch batch batch and age differences will become the advantage of transportation and health. For example, in a large amount of production of pig farms, it means that the number of transport vehicles used will be reduced, which significantly improves biological safety.
Work Plan
The following table shows two types of major work plans for two types of management (mating, M, childbirth, F and weaning, W).

It can be seen from the above table that breeding, childbirth and weaning work is more widely distributed in 3 weeks. However, it seems to be an disadvantage in 4 weeks, it is indeed a advantage: 2 weeks can exempt the most important tasks (mating, childbirth, and weaning), can help better arrange other activities, such as agricultural work , Holiday, training, maintenance, general cleaning, etc …

The optimization of the facility

If we only consider the sow facilities, there is no considering weaning or breeding facilities, a significant advantage of 4WBF is the optimal utilization of the delivery. : Since childbirth is carried out every 4 weeks, the lactation is 3 weeks, so it only needs birth to cooperate with a childbirth batch. According to the example above, a 250 sow, a pig farm, 4 weeks, will take 50-55 birthbs, while 3 weeks require 75-80 birthbirth. On the other hand, 4 weeks require more non-production cycle sow facilities, because there is a large amount of weaning sow (but we must remember that the delivery bar is more expensive than non-production cycle sow facilities)

Keeping batch size On the other hand, holding batch integrity is the most important disadvantage of 4 weeks, because most of the return is rule, so it will be detached batch. This fact forced the pig farm to find a fisherous pig estrus. The pig farm must use hormones such as tetrakenone to do the same period, and in the next batch (56 days later) or jump a few estrus until the estrus composition (about 84 days). This involves an increase in non-production days and an additional cost due to hormone use. Obviously, when the pregnancy of the pregnancy is better, these negative effects will be small when the reproductive loss is less.

Use the milk mother pig strategy

Strictly implement batch delivery to make the use of the milk sow are difficult, especially when using 4 weeks, due to childbirth Most piglets in the house are almost at the same age. A strategy that can use the cream sow is a small delivery house, which uses the mating sow as a milk mother pig. This facility also allows some sows that are separated from batches, although this may have a negative impact (the weaning batch is not strictly separated according to the age, the batch is different). Four-week batch production (4WBF) Conclusion

In short, 4 weeks batch production is also the choice of small pig farms, which is different from the traditional 3 weeks batch production system. There should be an assessment in each case.
