Batch production features
Batch production advantages:

Allow small farms to weaned a large number of pigs only weaned, through limits, trucks and transportation The company, etc., enters improvement of biological safety, allowing more pigs that are allowed by the same location or a single source to improve the health of pigs to reduce death losses (2-4%), increase the average daily weight and feed conversion The rate is more accurate to make the pig feed budget. By concentrating the survival rate of pigs, improve the accuracy of the sow vaccination process, the specialization of pig breeding and reproductive personnel, breaking the batch-produced disease cycle, and improve the potential possibilities of the child’s breast milk. Allow the staff to have a rest day, holidays, and a double bathroom.

Batch production requirements:

It is difficult to supplement the back of the mother pig or empty sow, the farm needs to provide space for the management of sow, and use the corresponding model to control estrus cycle, limit The amount of breastfeeding sow or no, it is necessary to deal with the latency or unsuitable weaning sow, it is difficult to manage the sow of the backward, and there is a low number of days of weaning to the first estrus. In the busy production, there will be additional labor needs. You need to use hormone therapy to manage the post-prepared sows and the sows, strong flushing rooms, and supplement the number of days of breeding sows, may need to increase the rescue space to add only some pigs. Milk, semen suppliers need to have a number of large amounts of transportation of semen each year.

The advantages and requirements of batch production are reflected in batch production, and batch production has been well practiced in the United States.

The situation of different batch production is shown in Table 1, the batch production system selection, the epidemic batch system is a two-week batch (10/2), four weeks (5/4) and five weeks Batch (4/5). The following mainly introduces the four-week batch (5/4) batch production plan.
Table 1. Summary of different batches of production.

four weeks (5/4) Batch production points :

Five groups of mother pigs, all four weeks, only feeding a sow that will not be recovered, sows and small mother pigs without circular weaning is difficult to divide into a batch. For a week, weaning aged 15-22 days; less than one week, weaning age is 18.5 days, in order to improve efficiency, the production is still used for 13 times, let the sow in delivery during 4 weeks only one week There is only little or no sows, weaning, feeding, and production in the first two weeks of every four weeks, weaning, feeding and production period, need additional labor and time, without weaning, feeding, Two weeks after the production, the time required to rest, the needed egg inventory is about 6.2 times the number of rivers.

Production to surrounding production (5/4) graduated conversion step:

Consult the veterinary use of alkene The estrus product delays the estrus of the sow and the use of doses. If the farm can correctly use allyl pregnancy products to delay the estrus of the sow and keep the mother pig period until the next feeding cycle, the batch production conversion process can make the batch production conversion process more smooth,Dramous sows need to use the product on the day of the day or the day, 24-hour fed allydene pregnancy, and maintained at the same time at the same time, give the milk mother pig feeding products every day, the effect will be better, finally From the original 20 breeding groups into five feeding groups,

retains the dramatic sowing day:

Over-milk group 4: on Thursday, the product is not used in Monday,

Draft Group 3: After 7 to 8 days of products, on Friday,

Over the Breathing Group 2: After 14 to 15 days, on Friday,

Diction Group 1: After 21 to 22 days of products, on Friday.

From the week-batch production system to the surrounding batch (5/4) system, the above steps need to be repeated 5 times

adjust the time to use according to the number of sows to the emotional days. Consult the veterinarian to ensure product use time, dose level, and number of tips, feeding within 7 days or 7 days, to help the head sow and the thin and weak sow, consider injection of pregnancy in the breast, consider isolation The first batch of sows and fed more dense mammal feeds during childbirth, in order to help the breast pigs ovulation as soon as possible, it is best to freely eat in the production period and the breastfeeding period.
In order to make the reserved pig batch, the reserve pig needs a detailed estrus (the number of breeding needs is more than 10% of the reserve pigs, before the breeding week, at least 14 days ago The above delayed allyl pregnant drug (calculated with the veterinarian);

To give the pregnancy, wear the sizzling, the delivery house needs to be empty, clean and disinfect in 2 to 3 days, then transfer The heavy sow will be given to the child;

The number of breeding is now 4 times the original week. In order to prevent the breeding, the pig farm requires more breeding people, which means cross training, can use other positions to breed;

If Monday starts to breed to Wednesday, most maternal pigs will Will pay in Wednesday to Friday;

Every 4 weeks require additional labor to help childbirth and dry pigs, the peak of childbirth is extended to 24 hours, will help reduce death and death before weaning;

Batch production usually can’t find a nurse sow, if used to replace the mother pig, you may need to install auxiliary facilities, will be earlyDifferent milk pigs are placed in it, and feeding additional dairy products, otherwise the farm may see the increase in death, and the production results are reversed;

After the sow is delivered, it will immediately carry out batchmast, ensure All pigs only get as spoiled milk;

The choice of breastfeeding sows may need to install a rescue facility, put early weaning into and feeding the dairy products for supplement, once the batch system is established, farm It takes a feeding every four weeks.
2. What do you need to do for technicians?

Need to provide constant training and supervision to the skilled person, ensure planned rest to prevent tiredness, record breeding breeding information: sow number, technical personnel, time, semen number. Recalling the information of the non-breeding technician’s fragmentation record: the total number of births, the total number of products, the number of services, the number of mating, weaning to the first breeding interval, childbirth, reproductive date and time, semen number. It is important to care about employees.

3. Summary

The breeding work of the pig farm is actually a systematic engineering, requires sows (rearing sows, sows), boars, piglets, breeding The mutual cooperation between the various parts of technology and technicians, but also follow the principle of wooden buckets, so various parts and at all stages can not be relaxed, although pigs are the main force of breeding, but the work of breeding technology and technicians also work to the whole pig Field breeding production has great influence, only scientific and human disposal can be achieved, in order to achieve the final success of breeding work, forming the final productivity of pig farm farming.
