For a family farm that does not exceed 350 sows, use three weeks Batch production strategy 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 every three weeks, weaning once every three weeks, and each three weeks is in place, which 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.

2, how to supplement the mother pig after three weeks after production?

When the reserve sow can add to the three-week batch production, if the reserve pig cannot participate in the three-week batch cycle, there may be problems in production, of course, this is true for all batch. Important is that the pig farm has to build a sufficiently reserved sow “water storage” to make the reserve pigs into the pigs in a timely manner. The reserve sow should be introduced in the backup group of 95-100 kg, or from the reserve group produced from the three weeks of the field before they expect the mating date. Reserve sow is usually included in the breeding plan for about 5 days after present.
belowThe flow model of the porcine breeding target is satisfied with the fare pig in their own 2nd, 3 or 4 estrus. If there is a problem in the same period of the rear stock, some chemicals, such as 0.4% tetrakenone (a kind of pregnant hormone-like substance, usually used as a sour glycery), etc., this requires veterinary consultants with your farm discuss. 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 meet the breeding objectives. 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 being phased, the irregular cycle can be reshaped (we can use a quarterly estrus to estrus.
5 batches of pregnant sows (which may have empty), but require 6 sets of piglets to meet operational requirements.
The annual update rate of the pig groups using a three-week batch is 40%, which may be better than the batch once, indicating that the system is not very wasteful to the sow.
Assume 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 breast pig how to arrange?
The three-week batch system is not suitable for some suggestions about the European Union on welfare pigs. It is relatively simple to have a three-week batch production with artificial insemination (AI). 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 a AI boar can be diluted to 16 to 20 semen once. If you choose to purchase Ai semen from the outside, the adult boar that is retained can be used in the field.
5, three weeks of batch production of breastfeeding sows?
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.
WEEK3WBF12345678 childbirth room 1 entry – product laud milk breast milk enters – Production of laud milk Birth chamber 2 kernel breast milk enters – Production of breast milk breast milk into – production

This system allows for a week of cleaning time, Sow can be used 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 in the UK. 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.
Furthermore, with the increase in the number of modern varieties, it can be re-allocated by using 4 foster sows after breastfeeding. Pigs. 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, only 4 sows in 100 sows every week, they all took a 14 to 16 heads, and there may be 8 sows in the next week, but because they have different times, they will not It is conducive to foster and management. But after using three-week batch production, these extreme situations are unlikely to appear.
Childbirth is completed in a relatively tense period, and now it has been once every three weeks, and the rest of the family members can help childbirth and implement transition management between several people. If the childbirth time is very tight, it is necessary to use 1 ml of clow (D-chloro-allyl alcohol) to do in the same period of delivery. When a workload begins to increase, family members can generally help, this theory applies to familyFarm or collaborative team with strong spirit.

Piglet Weaning time can also be adjusted because it happens every three weeks, which remains the time with the hollow column. 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.
6, how to arrange for the three-week batch production in the production?

There are two possibilities of two arrangements. Because the pig is weaning (7 kg) at 4 weeks old, the conservation target requires that they reach 30 kg at 10 weeks old, which means that 2 breastfeeding batch times. This can be provided in the following ways:
a) weaning piglets are raised from 7 kg to 18 kg in the insulation column, about 3 weeks (pay attention to the time of cleaning), then the pig moved to a relatively cold inventory The rest of the three weeks. Or
b) Weaning piglets have been raised from 7 kg from 7 kg (6 weeks) to 30kg (6 weeks). This requires all columns to provide heating facilities (reducing cleaning and moving time).
Due to fewer rooms in weaned areas and growth / fattening areas, the temperature is relatively easier to control.
7, how to arrange the fattening house for three weeks?
The 30kg piglets are placed in fattening houses. After 10-12 weeks, 4 batches can be listed. Or use the growth of the pig to raise the pig to 45kg, namely a three-week batch.
What the theory is used to use a good 4 batches of growth fatteners. If you don’t grow up for sale within 22 weeks, you need to provide additional fattening houses. Note that the pig house must guarantee the EU breeding regulations, which forces the pig’s transfer of about 30 kilograms or 50 kg, but it is definitely not 65 kg.
The ideal weaning piglet – fattening growth system is 30 kg to 95 kg, which means that the pig only needs to be transferred twice before slaughter. This reduces the stress frequency of pigs, which reduces cleaning.Room and moving pigs only work. In the US and Spain investigations, even some farms may directly feed from weaned to fattening. 8, three weeks of batch production of weaknesses

In the three-week batch of pig flow model, 10% of the smaller weaning pigs were dedicated to the care bar, still can Use three-week batch technology. 10% is marginalized to the care bar, three weeks, can be re-incorporated in the next batch or next batch. Note that the pigs that have just been weaned cannot be incorporated. The purpose of doing this is to reduce the variation of fattening pigs, rather than placing more fragile new cutting pigs under more infection pressure. Another advantage of three-week batch production is that it is relatively concentrated by weak pigs, so it is worth spending time to take care of them. For example, 10 sows per week, 10% weaned pigs are sick, then only 10 short-term sows, the batch unit of 30 sows in three weeks, concentrated 30 weak pigs. 9, three-week batch production of pig sales arrangements

The pigs produced in the three-week batch, allowing farms to use larger transport trucks to sell pigs, some degree This reduces the cost of transportation. It is also very advantageous for the Miao pig production field, because the farm produced in 10 sows per week, there is generally only 100 dairy pigs. Implementing three weeks of batch production, 30 sows in each batch, there will be 300 wear-sized weaning pigs, which will bring more contracts to the farm, and achieve full load of full / full easy.

After fattening, animals can still sell weekly, if needed, can have a three-week empty bar time (must be prepared to empty and clean the next batch of pigs). In this way, the farm fattening house will be cleaned like a delivery house. At the same time, reduce the number of sales reduces transportation costs.

10, three-week batch production pig flow model

The flow of pigs is so easy to understand. Due to the biological characteristics of pigs, the three-week batch is uniquely allowed to concentrate and specialize in the activities of the family farm. This ensures that holidays and weekends can rest. Traditional routine routines have been broken, allowing more social people to enter the pig farm. If they can also get such a treatment, actually the pig farm will easily find employees.
Because the pig farm has different states in three weeks,/ Full-time is easier to achieve, farm production is more regular.
Table 3 Timetable of sow production incidents in the three-week batch

Zengyuan childbirth group faulty milk group mixed group 1A

The above analysis, such as the first week of the A group of sows, weaning in the fifth week, then group A group of mother pigs in the sixth week; Similarly B group of sows on the fourth week, weaned milk at the eighth week, then b group mother pigs were breed at the ninth week, and the remaining groups were pushed. A group of sows retake the bed in the twenty-two weeks, and B group mother pigs returned to bed, and cycles in turn.
11, three weeks of batch production advantages

· All growing pigs strictly advance, will result in alleviation of disease infection, thus improving pig growth speed.
· □ Regular flushing and disinfection of all produced animal groups

· □ Feed development – Implementation stage feeding

· □ pig only movement reduction
· □ Can better utilize vaccines, large bottled vaccines can be fully used (some bottled vaccines are often discarded).
· □ Staff in different weeks of work specialization

· □ will pay more attention to breeding procedures

· □ Piglets is more easy to cultivate

· □ Must reduce transportation cost

· More widely accepted by society – family farm with time vacation

12, three weeks

· In order to maintain the expected yield, each batch requires additional a few heads;

· Randolysis, but any batch system is true;

· □ If you need to change to three weeks of batch production, it will increase pressure on the current weekly batch, in 6 Partial loss may be brought about within the month.

Table 4. Traditional weekly continuous production batch introduction map

13, except for batch production mode other than three weeks

If the farm is aligned according to the production, rather than pursuing each child’s annual fetal, the three-week batch model will be accepted, because this can truly all / full. In addition, there are two models, once a week, 10 days mode or 2 weeks, 4 weeks or 5 weeks batch models, usually according to the size of the farm, based on maximizing income The principle of minimizing investment.
14. How to convert from weekly continuous production to three weeks batch production?
As with any changes to the company, we need to make a confidential thinking and planning before making changes. Mainly relying on a sufficient reserve sow reserve, a short time changes the day to abundance and the variability of the farm and growth pigs. Table 2 shows the schedule of the production event. The farm must cooperate with a farmland that provides a reserve sow. Some piglets below 21 days are also acceptable because this is part of the long-term benefits program of the Pig.

The above table assumes that 8 weeks of introduction period is introduced. Note that after they arrive during their second, 3 or 4 estrus, they can be used as a reserve sow to participate in a breeding to ensure that the propagation goals are reached. Timely reserve sow is essential to this program, the rear sow must be introduced in the weaning week (here, it assumes that the post-prepared pig tetrane is deactivated after 5 days of estrus).

Pay attention to the establishment of a batch softener from three different per-cut milk pigs:

○ First weaning a week of sows, feeding 0.4% tetrakenone 7 Days to delay the cycle time of about a week. Alternatively, the sow is removed from the childbirthhouse, and the pigs are rushed to the pig house with straw, and then weaned during the 5th week.

○ Normal weaning is carried out at 4 weeks

○ There is also a group of sows only breastfeed for three weeks.

This can release a large amount of bedding for the expected delivery, because the past weekly production has a sow on the production of sows every week.
Therefore, it can be seen from Table 2 that the rear sow (100 kg) must be prepared 9 weeks in advance, and the general farm is within 30 weeks to transform success. The transformation of fattening may require additional 16-18 weeks.
Three-week batch production summary

The three-week batch production can provide an optimized yield to the traditional family farm, and improve the pig farm production method of profits, and it is more likely to be domestic small and medium-sized The pig farm accepts. However, each pig farm before making such a transition decision, in order to unify thinking carefully, the author thinks that the pig farm needs to discuss multiple discussions and then implement it, the successful grasp will be larger.
