What do the piglets prepare for the nursery?

1. When the piglets are transferred to the pig house, the physique is weak, so it is necessary to pay attention to the ventilation and insulation of the piglet house, control the temperature of the pig house, and do a good job of ventilation while keeping warm, eliminate harmful gases, and provide a more comfortable growth and living environment for the piglets.

2. Pay attention to the excessive feed of piglets and reduce the stress of piglets caused by excessive feed. In pig production, according to the overall situation of the pig herd to flexibly adjust the feed ratio, for the sick and weak pigs can be appropriately extended to feed suckling pig feed or feed excessive time, and for the transfer of large weight, strong piglets can be the opposite, control the cost of pig breeding, increase economic benefits.

In recent years, viral bacterial diseases have spread in the small-scale operation of pig farms, and more and more complex in the prevention and control, and for the nursery piglets to tremble, the disease is fatal, the nursery piglets are out of the mother's protection, but their own immune system and digestive system are still relatively perfect, this stage is the most vulnerable, therefore, it is necessary to increase the protection of the nursery piglets in the feeding management.

<> Nursery pig feeding management Environmental management Nursery pigs should be thoroughly cleaned and disinfected before entering the pig house. After disinfection, it should be ventilated and purified for 3 5 days before entering the pig house. Within 1 week of entering the barn, the feeding, sleeping and defecation behaviors of the nursery pigs should be adjusted and positioned regularly.

In order to make the piglets feel comfortable, the temperature of the pig house should be controlled at 27 25, and after 2 weeks of cooling, it will be gradually reduced to 21, and the ambient humidity of 55% and 65% should be strengthened, so that the pig house can be kept dry under the condition of ensuring temperature; Clean the pig house every day, and don't let waste accumulate and affect the quality of the environment. The feeding density of fattening pigs should not be too high, a column of 15 20 heads is appropriate, the density is too high will cause piglets to bite each other, and will increase the emission of bad gases, resulting in a decrease in air quality in the house, easy to cause respiratory diseases.

Scabies mites, worms and other ectoparasites cause damage to the piglet's immune system and decreased resistance, and will lead to slow growth of piglets, increase the cost of breeding, so the farm must do a good job of nursing and insecticide, in weaned piglets after 2-3 weeks of storage to choose the internal and external parasites effect of broad-spectrum, efficient and non-stomach deworming agents for collective deworming. Weaned piglets were vaccinated against swine fever at 55 to 60 days of age and foot-and-mouth disease vaccine at 70 to 75 days of age. Vaccination plans can also be reasonably formulated according to the local epidemic situation.

It should be noted that two or more different vaccines cannot be injected at the same time, so as not to interfere with each other and affect the production of antibodies.

Piglet care management needs to pay attention to the hygiene of the pig house, at the time of weaning, the land can be completely isolated from other sows or all pigs, after birth, in the shortest possible time should eat raw milk, during the growth of feeding should be kept full of closed feet and clean drinking water, and you can add some vitamin C or vitamins in the first posture of drinking water.

To separate the sow from the piglets, during the weaning period, the sows should be driven away, leaving only the piglets, to pay attention to the piglet feeding, the diet should be balanced, the disease of the piglets, the prevention and control points should be widened, and the disease should be dispersed in time when sick, pay attention to disinfection, and do a good job of piglet guardrails in the wild potato pigsty.

It is necessary to increase protection, reasonably arrange the vaccine plan, conduct physical examinations on piglets, prevent various diseases, carry out thorough disinfection and spring cleaning before piglets enter the rotten pig house, ensure ventilation to keep the pig chop house dry, and clean the pig house every day to ensure the quality of the environment.

Reasonably grasp the weaning time of pigs, in the weaning time in the Tanyu River, timely the mother Jing teasing pigs to drive away, often carry out physical examinations on piglets, prevent various diseases and spinal diseases, pay more attention to the nutritional value of pig feed to improve feed nutrition, and raise piglets separately.

It is nutrition and hygiene, temperature, generally these three directions, as long as you grasp these several, there will be a healthy piglet.

1. Clean pig house, try to create a clean pig house as much as possible: there should be no manure pollution, no dust sterile environment, so that there is no pathogen that causes disease, and pigs will not get sick. 2. Control the health of the pigs in the house, select the sick and weak pigs in the nursery stage, and the first is to control the health of the pigs

Because if the pig that enters the barn is sick, the pig can be transmitted to other pigs, and finally it is a serious disease. At the same time, it is also necessary to maintain the uniformity of the pig herd, otherwise the size is uneven, and the weak pigs tend to become weaker and weaker, which affects the overall slaughter and is easy to cause disease and death.

Be sure to ensure environmental hygiene. And feed him more foods that contain vitamins. Eat smaller, more frequent meals.

Because the piglet's digestive system is not fully developed, give it a little cooked feed. The temperature in the barn must be well controlled, not too cold or too hot. Be sure to observe the physical condition of the piglets on time.

It is necessary to ensure a balanced nutrition.

Generally, the weaning body is more than kilograms in 28 days, the feed-to-meat ratio during the nursery period is generally about 600 grams, the daily weight gain is about 420 grams, and the weight target for 70 days is more than 25 kilograms.

Piglet nurseries should be built in the north to build closed pig houses, in the south can be built semi-open pig houses. A single row of pigs can be built for a small feeding scale, and a double-row pig house can be built for a large feeding scale.

The direction of the single-row pig house should be north and south, so as to make full use of the sunlight in winter and increase the temperature of the pen. The double-row barn should be built in a north-south direction, so as to ensure that both rows of pigs can fully receive sunlight. If it is built in an east-west direction, the pig barn on the north side will not see sunlight all year round, which is not conducive to the health of wild boars.

Figure 5-4 The basic requirement of a nursery house for single-row piglets is to keep warm from the cold. Like the nursing house, the insulation performance should be good, and the wall should be preferably made of 24 cm hollow brick masonry, and the wall should be plastered inside and out. The roof should be covered or multi-layer composite roof.

Sleeping areas should be set up in the nursery school.

The sleeping area is generally a meter, and the ground should be laid with 20 cm thick wood residue or crushed corn stalks, and then a layer of wooden planks is laid on top to ensure dryness and warmth, and prevent and control the diarrhea caused by cold when the wild boar is sleeping.

The ground is required to be laid with 20 cm thick wood residue or crushed corn stalks, and a layer of straw or wooden planks is laid on top, which can isolate the cold and damp cement floor from the invasion of piglets, which is conducive to keeping warm.

Breeders should clean the manure frequently, change the grass once every 3 5 days, and dry it in sunny weather. This warm floor is drier and warmer than the concrete floor, which significantly reduces diarrhea and diarrhea in piglets. Especially in the cold winter in the north, this kind of warm ground can increase the survival rate of wild boars by about 20% compared with cement floor.

A sports field should be built outside the nursery house, so that the wild boars can move freely on the sports field every day, increase the amount of activity, and improve the feed intake of the piglets.

The wild boar cubs get enough exercise, become strong and rarely get sick. This not only reduces the cost of drugs, but also increases the growth rate of the piglets. The nursery is equipped with automatic drinking fountains and automatic troughs to ensure adequate and clean drinking water and nutritious feed.

Figure 5-5 The best window in the north of the nursery in the cold area of the double-row piglet nursery should be less, generally 60 cm to 80 cm, and the plastic cloth should be sealed in winter to increase the thermal insulation capacity. The south window can be larger, usually a meter, and still have to be covered with plastic in winter. Set up special ventilation ducts to avoid ventilation in winter and reduce the temperature in the pig house.

Heating facilities should also be installed in the house, and artificial heating will be carried out when the temperature is too low.

(1) Reasonable grouping.

In order to improve the uniformity of piglets and ensure the smooth operation of the "all-in, all-out" process, from the piglet transfer to the beginning of a reasonable group according to its breed, male and female, physique, etc., and pay attention to observation, in order to reduce the occurrence of piglet fighting, for individual sick and weak pigs as long as separate feeding and special care.

2) Three-zone positioning.

From the date of the piglet transfer should strengthen the positioning work, this work is generally completed within 1 3 days of the piglet transfer, the sooner the better, so that each column is formed in the drinking area, rest area and fecal area of the three area positioning, so as to maintain the environment in the house and create conditions for the management of the pig herd.

3) Environmental control.

Pay attention to ventilation and insulation, the room temperature of the rearing house is generally controlled at 22 28, the humidity is controlled at 60% 65%, due to the large number of pigs in the nursery house, high density, a large number of harmful gases (ammonia, carbon dioxide, etc.) can often be produced in the cold season, so it is necessary to do a good job of ventilation while keeping warm, eliminate harmful gases, and provide a more comfortable growth environment for pigs.

4) Feed transition.

In order to reduce the stress of piglets due to feed transition, it is recommended to carry out feed transition with the following scheme: piglets are fed suckling pig feed 1 7 days after transfer; 8 9 days fed pellet feed Piglet feed = 2 1;10 11 days of pellet feed Piglet feed = 1 1;12 14 days fed pellet feed Piglet feed = 1 2;After 14 days, all piglets are fed. In the production can be flexibly grasped according to the overall situation of the pig herd, for the sick and weak pigs can be appropriately extended feeding suckling pig feed or feed transition time, and for the transfer of large weight, strong piglets can be reversed.

In this way, production costs can be regulated and production benefits can be increased.

In the first week of entering the breeding house, the piglets should be fed restrictively, only eating until they are full, so that the piglets are hungry and full, which can not only enhance digestion, but also maintain a strong appetite, and can effectively prevent the occurrence of edema and diarrheal diseases. High-quality full-price feed is required for finished piglets.

Reasonable feeding: according to the actual situation of the pig herd, add growth promoters or antibacterial drugs to the feed as appropriate. Perform drug prophylaxis. In addition, in the process of feeding, it is necessary to properly clean the trough according to the actual situation to ensure that the feed in the trough is fresh.

5) Vaccination.

According to the immunization procedures, do a good job of various immunization work in a timely and accurate manner, so that the injection site is disinfected accurately, the immunization dose is sufficient, one pig is injected, the head is injected, and the operation is standardized to ensure the immunization effect.
