How should piglets raise standards

The benefits of piglet fostering as a method to balance the number of piglets per sow or to provide a better growth opportunity for congenitally deficient piglets are beyond doubt. With this done, each sow can produce one more weaned piglet each year.

First, the principle of foster care

1. Foster piglets need to eat enough colostrum as soon as possible.

2. The closer the sow farrowing date is, the better, usually the sow birth date does not differ by more than one day.

3. Diseased nests must not be fostered in healthy nests to prevent cross-infection of the disease.

4. Increase the volume but not the smaller, increase the intensity and not the weaker. When postpartum piglets are fostered in the prenatal litter, a large size herd should be selected. When prenatal piglets are fostered in the postnatal litter, they should be picked with a small weight; , We must pick a large body and strong physical foster, to avoid large differences in piglet weight, affecting the growth and development of piglets with small body weight.

5. When sowing, it is necessary to estimate the sow's feeding ability, that is, to consider whether the sow has a sufficient number of effective nipples, and to estimate its maternal behavior and lactation capacity.

6, the best choice for sow parity. Or the offspring of the young sow should choose the young sow, and the offspring of the old sow should choose the old sow.

7. Spread the sow's urine on the nursery piglets, or sprinkle the same smell liquid on the piglets of the whole herd to mask the odor of the piglets and reduce the sow's rejection of the nursery piglets.

8. Before piglets are fostered, it is necessary to make earmarks and other marks and records to avoid pedigree confusion and the search of post-production management.

Whether the newborn piglets are fostered or not, the work of fixing the nipples should be done well. Fixing the nipple can reduce the fight and fight for milk of piglets and ensure the early consumption of colostrum, which is a good way to achieve balanced development of piglets. The fixed nipples should be appropriately adjusted according to the wishes of the piglets. Weak piglets are usually fixed on the first two pairs of nipples, and strong piglets are fixed on the rear nipples. Other piglets should not eat the same nipples.

二 、 Fostering time

Within 3 days of birth 4-7 days 8-14 days 15-21 days

三 、 Fostering method

Individual fostering: insufficient sow lactation, excessive litter size, and uneven piglet size, you can choose a strong foster foster sow.

Whole litter fostering: When sows are postpartum free of milk, frail and sick, postpartum death, have bite vulgaris, piglet diarrhea, old sows have a small number of litters and are eliminated in advance.

Combined littering: When two litters of sows are at similar stages of production and the piglets are not of equal size, the piglets are divided into two groups according to their strength and size. Group piglets, the other sow feeding a stronger group.

Two-day fostering: Wean piglets with high lactation and good maternal litters in advance around 18 days, sows should be kept around 10 days old to grow healthy piglets, and 10-day-old sows should be brought in for 10 days.

24. Responsible personnel

仔 The piglets within 0-3 days of age will be nursed by the leader of the midwifery team, mainly to adjust the size and number.

Fostering work at the age of 4 days and above is the responsibility of the supervisor

V. Inspection Standards

The uniformity in the nests of each unit is basically the same, and it is advisable that no piglets snatch milk during lactation.
