There are skills in weaning piglets, and the feed environment must be transitioned!

 Farmers and friends all know that the main source of income for pig farms is sows and piglets. The prenatal and postpartum care of sows and the weaning of piglets are the most concerned things for pig farmers. Whether the weaning of piglets is successful or not determines the growth rate of piglets in the nursery stage and even the growth rate of piglets. The length of time for pigs to be released, so the weaning of piglets is very important for pig farmers, so what are the techniques for weaning piglets? I have two suggestions for you. Interested friends come and have a look!

1. Transition of feeding and management of piglet weaning skills

 1). Gradually reduce the frequency of breastfeeding. 5-7 days before weaning, piglets are fed 5-6 times a day, gradually transitioned to 1-2 times a day, and the last weaning.  

2). Gradually reduce the feeding amount of concentrate and green material. Before weaning, the sow should gradually reduce the amount of concentrate and green sweaty feed, and appropriately increase the proportion of roughage in the diet to prevent mastitis in sows during weaning.

 3). Within 15 days after weaning, it should be raised according to the method of lactation, and fed once at night to avoid starvation of piglets. Do not overfeed each time to keep the piglet's appetite strong and prevent diarrhea. At the same time supply sufficient clean drinking water.

 2. The transition of piglet weaning skills to the environment

 1). Gradually reduce the time spent with mother and baby before weaning. During the weaning period, the sows can be driven out of the pen during the day to separate the mother and the calf. The sows are driven back to the original pen at night.

 2). In addition to selling after weaning, those who practice self-propagation and self-raising should not be transferred from the original circle as much as possible, and do not immediately mix the group and litters, just drive the sows away.

 3). The transfer and brooding should be carried out after weaning for half a month, after the feeding and excrement are normal, and the piglets should be allowed to move together or eat in the same trough within 3-5 days, and then they will be reared together after being familiar with each other.

 If the feed management and environment can be transitioned well, the piglets can basically be successfully weaned, and healthy growth after weaning is no longer a problem. Therefore, pig farmers must do a good job in the transition of feed management and environment when weaning piglets, so that the probability of successful weaning of piglets will be greatly improved. Finally, I hope this article will be helpful to pig farmers. If you want to know more about agricultural technology, please pay attention to Hui Nong Academy!

How are pigs raised?

 Pork is an indispensable meat product in our daily life. At the same time, my country is also a big pork consumer. The demand for pork in the market has always been quite stable. In the past two years, the price of pork has soared, and the pig raising market has ushered in a favorable situation. Many people have joined the pig raising army and want to share the cake. However, in order to ensure good economic benefits, it is necessary to start with basic feeding and management. Now I will share the pig breeding technology with you.

1. The main points of breeding boars

1）. In the process of raising breeding boars, the main goal is to improve the breeding ability of the breeding boars so that they can play a better role in the process of piglet breeding. Breeding boars are mainly fed with concentrate, with more than 3 kinds of feeds including coarse, fine and green. In peak breeding season, high protein feed such as beans and eggs should be added to improve breeding ability and semen quality. And when the weather is cold, you can add some more seasoning.

2）. It is best to control the body weight of the boar to be neither fat nor thin. If it is too fat, it will affect the libido, which will affect the breeding process; if it is too thin, it means that the impact is not good, and if it is serious, it will threaten the normal growth of the boar. development.

3）. Generally speaking, boars should ensure a daily amount of exercise of 800 to 1000 meters, and exercise should be carried out half an hour after the boars eat. When the boar pen is built, a single pig is built, and the sports field is designed to be slightly larger.

4）. Check the semen quality 3 times a month, mainly check the density and vitality of sperm. In particular, semen quality must be checked before a gilt is used or before an adult boar is transferred from a non-breeding period to a breeding period. If artificially inseminated boars are used, the semen quality should be checked every time the semen is collected.

2. Main points of breeding sows

1）. When breeding sows, three meals a day should be fed regularly and quantitatively. The daily concentrate of breeding sows should be kept at about 2.5 kg, which is basically the same as that of breeding boars in winter, and in summer Also add some green fodder to the feed to ensure nutritional balance.

2）. When the body weight is about 50 kg, the material should be properly controlled, and the body fat should not be too fat. When the body weight is about 70 kg, inject parvovirus and Japanese encephalitis vaccine (repeated after 15 days), and pay attention to the estrus performance of the sow. . The year, month, and day of the first estrus of the sow are recorded in detail to calculate the next estrus for breeding.

3）. For the breeding of sows, try to choose in the morning, evening or when the weather is cool, and repeat the breeding for 12 hours. If the sow did not come into estrus 21 days after mating, the sow was transferred to gestational feeding.

4）. Pay attention to the clinical signs of the sow. Once the sow is sick during pregnancy, special attention should be paid to the use of medicines. Medicines that may cause abortion must not be used. In addition, if it is summer, it is necessary to do a good job of preventing heatstroke and cooling; if it is winter, pay attention to keeping warm and prevent cold, and the sows will enter a thoroughly sterilized farrowing room one week before giving birth, and prepare relevant delivery supplies.

3. Feeding points of piglets

1）. When the piglets are born, temperature control is very important. Try to control the temperature of the delivery room above 20 degrees, especially in winter, because the outdoor temperature is low, you should try to ensure that the temperature is consistent with the temperature of the breeding room. Avoid catching a cold due to incompatibility with the temperature.

2）. In 2-3 days after the birth of the piglets, the method of helping the weak and suppressing the strong should be adopted manually, so that the piglets can suck the fixed teats, and try to fix the weak piglets on the first few pairs of teats, so that the piglets can grow evenly and robustly.

3）. Drinking water should be supplemented from the age of 3-5 days, and water containing 0.8% hydrochloric acid should be used for the age of 3-20 days. After 20 days of age, use clear water to supplement the incomplete secretion of gastric juice and digest pepsin. Weaning weight. Feeding attention should be paid to the supplementation of iron, selenium, water and feed. Generally, feed is started at 7 days of age. The method is to put a small amount of feed on a dry and clean wooden board, and then change it into the feed trough after starting to eat. When starting feeding, be sure to feed 4-6 times a day according to the principle of "feed less and add more often".

4）. Weaning time should be well controlled, generally at 35-45 days of age, when the body weight reaches 4-5kg or more, weaning is the most suitable. Prolonged lactation period will affect the annual number of litters and the number of piglets produced.

In general, pig farmers should distinguish between different situations and different growth stages, and choose feeding and management techniques reasonably, so as to ensure the healthy growth of live pigs.

How to deal with the "hot snoring" of chickens in summer?

 There is a saying in chicken raising that "hot snoring, cold cough", and the frequent occurrence of "hot snoring" in summer has also become a major problem that plagues farmers.

Farmers all know that chickens are easy to raise in summer, with good ventilation and high temperature. Chickens are not easy to catch colds, and the incidence of respiratory diseases such as air sac inflammation is low. But raising chickens also has a summer-specific respiratory disease: heat snoring.

"Hot Snoring" Symptoms

The spirit of the flock is very good and the feed intake is normal. There is obvious phlegm in the throat of the chicken, and there is a clear snoring sound with the breathing. After dissecting the snoring chicken, it was found that the trachea, lungs, air sacs and other positions are relatively clean. Some chickens have been sick for a long time, and there will be slight bleeding in the throat.

All snoring chickens have a large amount of sputum in the throat, and the sputum is relatively viscous.

The pathogenesis of "hot snoring"

In the hot summer weather, chickens have no sweat glands to dissipate heat. At this time, chickens will open their wings, open their mouths to breathe, and take away excess heat from the body by breathing quickly.

When the chicken opens its mouth to breathe, the nasal cavity loses its filtering effect on the air. At this time, the dust in the air and the pathogenic bacteria will directly enter the trachea of the chicken.

The tracheal mucosa secretes mucus to wrap the dust and pathogenic bacteria, and then discharge it to the larynx through the tracheal cilia, and then the chicken excretes the sputum from the body or brings it to the digestive system by drinking water or shaking the head, so as to reduce the phlegm in the larynx.

But in summer, when the chicken opens its mouth to breathe, the air flow is fast, and the water in the sputum is evaporated in large quantities, forming sticky phlegm. These sticky phlegm is located in the throat, and it is difficult to be eliminated in a short time, and the snoring sound is formed along with the breathing process of the chicken.

The wrong treatment idea for "hot snoring"

Many people do not understand the "respiratory system", which is a symptom, not a specific disease. The pathogenesis of respiratory tract is divided into physiological and pathological pathogenesis. This kind of "hot snoring" is a physiological disease, which is a "conditioned disease".

Many farmers do not understand, and treat heat snoring as other diseases. They use a large number of Maxingshigan powder, doxycycline, tylosin, and even tylosin, azithromycin, etc., which cost a lot of medicines and have little effect , and even the symptoms of overdose such as black liver and kidney enlargement in chickens.

Correct prevention and treatment of "hot snoring"

To treat respiratory diseases, we must understand how the disease occurs. When we understand the cause of "hot snoring", we can no longer use a lot of antibiotics to control it.

This is a conditional disease, a disease unique to summer, and a consequence of chickens coping with high temperature weather. When the weather is cool, the chicken does not need to dissipate heat from the mouth, the filtering effect of the nasal cavity can work normally, and the snoring will slowly go down.

In daily management, the temperature of the chicken house can be reduced by means of fans, water curtains, roof sprinklers, sunshade nets, etc., and the snoring will naturally decrease.

If the snoring is severe, or the snoring time is relatively long, drugs that strengthen the resistance of the chicken respiratory mucosa and reduce phlegm can be used. At the same time with a small amount of antibiotics for anti-inflammatory.
