Spring Pig Precautions

Improved seed quality is the primary factor in raising the efficiency of raising pigs, and the quality of breeding pigs is a key link in the success or failure of raising pigs. Farmers who raise pigs on a small scale (especially those who have just entered the pig raising industry) often introduce pigs as the majority of the farmers prefer heavy pigs. They feel that importing large pigs is more appropriate. In fact, this will affect future production. Bring hidden dangers. During the introduction of spring, the following aspects should be noted:

I. Two preparations should be made before the farm is introduced

1, according to the actual situation to develop a scientific and reasonable introduction program, and do a good job before the introduction of various preparatory work.

2. Survey and selection of target breeding farms

(1) Select a breeding farm with a moderate scale, a high degree of trust, and a high level of technical services;

(2) Selecting the farmer should put the health status of the breeding pigs first;

(3) The pedigree of breeding pigs should be clear;

(4) Choose a better home after-sales service;

(5) Try to buy from a farm, otherwise it will increase the possibility of illness;

(6) Selecting a field home should be followed by indirect understanding or consultation, and then to the field and sales staff to understand the situation.

Second, to select the breeding pigs in the target field

1, production performance off:

Kind of boar: the requirements are pure, lively and happy, normal testis development, and not much effusion of the foreskin;

Sows: In order to purchase sows, we must select individual sows that are well-growth, have no morbid signs, respond to sensitive sows, have good genital development, and have large pupa and sagging cats with multiple nipples.

(1) A healthy body appearance. When choosing a gilt, physical fitness means that there are no defects or shortcomings that can interfere with normal reproductive performance. There are three aspects to pay special attention to: genitals, breasts, and bones.

(2) Sound fertility. The gilt should reproduce normally, the external genitalia should develop normally, and the small female in the vulva shows that the birth canal stays in the pre-development state. This type of sow should not be preserved.

(3), normal breast function. A gilt should have a sufficient number of healthy nipples, and gilts should each have at least six pairs of nipples separated by a suitable distance and a complete nipple.

(4) Strong bones. Swing gilts with foot and leg problems should not be kept because they interfere with normal mating, delivery, and breastfeeding.

2. Diseases and diseases:

Pigs require health, no clinical signs and genetic disorders.

3, environmental adaptation:

When introducing, comprehensive consideration should be given to the difference between this field and the seed supply field in the regional environment and the pig farm microenvironment, and the consistency of the environment of the farm with the seed supply field should be achieved as much as possible.

Third, breeding pigs enter the field and group five note

1. Pay attention to segregation first: Newly introduced breeding pigs should be kept in the isolation house first, but not directly into the breeding pig production area.

2. Pay attention to disinfection and grouping: After the breeding pig arrives at the destination, immediately sterilize the ground around the dumping platform, vehicle, pig body and unloading vehicle, and then remove the breeding pigs, and feed them in groups according to size and male and female;

3, pay attention to strengthen management: first give the breeding pig water, rest 6-12 hours before the supply of a small amount of feed, the second day can gradually increase the amount of feeding, 5 days before returning to the normal amount of feeding;

4. Attention should be paid to isolation and observation: After the breeding pigs arrive at the farm, they must be kept in isolation for 30-45 days and strict quarantine;

5, pay attention to exercise: after the weight of 90 kg of pigs, to ensure that each pig per day 2 hours of free exercise time, improve their physical fitness and promote estrus.

IV. Prevention of Seven Diseases Introduced in Spring Farms

The most common are swine fever, piglet paratyphoid, panting, Japanese encephalitis, infectious gastroenteritis, yellow and white piglets, blue ear disease. Before and after the spring will enter the peak period of swine fever, pig farmers should be as soon as possible injection of swine fever vaccine. In order to prevent yellow and white piglets, sows should be injected with E. coli 20 days before delivery. In addition to on-time injection of various vaccines to prevent swine diseases, another important measure is to do a good job in housing hygiene and strengthen feeding management.
