For family farm for no more than 350 sows, use three weeks Sub-production strategies can reduce labor costs. The farm needs to take a full production method to obtain profits, and maximize the farm production through accurate pig flowing. Three-week batch production can provide more profitable opportunities for the family farm.
1, what is the three-week batch production?
The three-week batch production is not a very avant-garde concept. In the UK, it is actually a widely used mature theory. In the 1950s, with the promotion of early weaned technology and the promotion of the British family farm to produce transformation. Three-week batch production has always had a larger market in Central Europe.

The family farm gives birth once every three weeks, weaning once every three weeks, and each three weeks is in place. This is the so-called three-week batch production. The system is based on the biological habit of the sow, as the pig flows can be divided into a batch of batch, the sows of the sow, all one of the three weeks, respectively. The 4-week-old weaning of the three-week batch production standards.
Three-week batch farm layout

summarizes in Table 1.

Table 1 Architecture requirements

Pig house rear preparation mother sow pregnant sow childbirth 7-30kg wear pig 30-95kg growth / fattening pig three weeks 3 group 6 group 2 group 2- 3 groups of 4-5 sets of Zhouzhi 9 groups of 16 groups of 5 groups 7 groups 12-14 groups
2, how to supplement the mother pig after three weeks after production?

When the reserve sow can supplement the pig group to affect the production of three weeks. If the backpare pig cannot participate in the three-week batch cycle, there will be problems in production, of course, this for all batches This is the case. Therefore, the pig farm has to build a sufficiently reserved sow “reservoir” to introduce the reserve pigs into the pig. The reserve sow should be introduced in the stand in the standing group, or from the reserve group produced by the fact that it is expected to be 95-100 kg before they expect the mating date. Reserve sow is usually included in the breeding plan for about 5 days after present.
Pigs in Table 2 belowThe flow model of breeding the target is satisfied with the fare pig in their own 2nd, 3nd or 4 estrus. If there is a problem in the same period of the rear, some chemicals, such as 0.4% quadrene (a kind of pregnant hormone-like substance), etc., this needs to be discussed with veterinarian consultants with your farm. Note that there are always three sets of sows, including one group to isolate three weeks.
3, how to update the sow in the three-week batch production?

Like all family farms, we must first reach a breeding target. The advantage of the three-week batch production is that 80% of the original mother pigs will have 21 or 42 days of normal cycle. When the number of populations is lower than the target or is phased, the irregular cycle can be reshaped (always with ate esthymide to estrus.

5 batches of pregnant sows (which may have empty), but need 6 sets of piglets to meet operational requirements.

The annual update rate of the pig group production used in three weeks of batch is 40%, which may be better than the batch of batch, indicating that the system is not very wasteful to the sow.

Assuming that all sows weaned on Thursday afternoon, most of the mother pigs will be in court next Monday / Tuesday. Because the centralized breeding occurs every three weeks, family members can better participate in all breeding and optimize production results. In a weekly production holiday, the performance of breeding work may be poor, and the natural gain rate will decrease.
4, three weeks of batch production boar how to arrange?
The three-week batch system is not suitable for some suggestions about the European Union on welfare pigs. It has relatively simple to have artificial insemination stations to make three weeks of batch production. At present, some professional services provided by some large-scale artificial insemination stations are better (even more than many new boars). The farm can choose high quality semen for artificial insemination. If the farm of 250 sows is a single-week batch production, there are 10 sows in theoret from 10 sows per week, and 30 sows are a batch, and only the farm products are only needed. 3-4 heads. The male muntier corresponds to 62-83 sows for every pig. It is imagined that the fertilizer boar can be diluted to 16 to 20 semen once. If you choose to purchase high quality semen from the outside, the adult boar that is retained can be used in the field.
5, three weeks of batch production of breastfeeding sowsGroup?
The three-week batch childbirth (4 weeks of milk) only needs to be 2 sets of delivery. The room occupation is shown in the figure below.

The system allows for a week or so, the sow can be taken in advance. This gives better disease isolation control conditions, and the pig house has a sufficient preparation time. If it is a week-batch production, a unit hollow bar is not common. Because from the traditional production of the weekly batch based on five branching units, the production of farms will be very tight. A) In order to maintain high yield, it takes a week of sufficient delivery space – transforming it into “6 branching units”, and then can be divided into two equal batch, or

b) reduces input The current childbirth area is directly divided into two equal batch. Each of the above two options has advantages and can increase profits, depending on the entire farm cost calculation and spatial configuration. Most farms, when childbirth facilities must be divided into 5 identical units, the whole process is more easily realized, and the farm is divided into 2 batches and not a weekly batch.

In addition, with the increase of the number of modern pigs, it is possible to regain pig breastfeeding by using 4 foster sows after breastfeeding. This depends on two conditions, one is to use the original empty bed for delivery home, and the other is a liquid feeding system. Of course, the twigents and cleaning workloads will increase.

Each batch has more maternal pig delivery makes it easier for fostering and breastfeeding in the top 3 to 3 days. For example, 100 mother farm has only 4 sows for delivery every week, they all take 14 to 16 heads, may have the next week’s 4 sows, each with 8 heads, but because they have different times, It is not conducive to foster and management will be messy. After using three weeks after batch production, these extreme situations are unlikely to appear.

Delivery in the past is completed in relatively tension, now is once every three weeks, the restFamily members can help childbirth and implement transition management between several people. If the childbirth time is very tight, it is necessary to use a happy child (D-chlorine pre-elevated alcohol) to give birth. When a workload begins to increase, family members can generally help, this theory applies to family farms or collaborative teams.

The piglet weaned time can also be adjusted because it happens every three weeks, which remains the time with the hollow bar. Piglets can also stay in childbirthhouse for a few days, farm still has time to clean childbirth area. This will let the broken milk better understand the food and water, the qualified weaning pigs move into the next stage.
