In the autumn and winter alternate season, due to the large temperature difference, it is easy to induce pig disease. Therefore, we must pay special attention to the management work of this period. Here is a brief introduction to the management points of the farm in the autumn and winter alternate seasons:

First, do a good job in warming the suckling piglets

1. Preparation before the birth of the piglet: The temperature in the delivery room should be kept at 22 °C three days before the birth of the piglet. The incubator should be disinfected (warm small room after the piglet is born), and the heat preservation lamp can be used effectively. The bottom of the incubator is equipped with a matching insulation floor to make the yin of the small room of the newborn piglet, and the yang of the sky (on), to balance the yin and yang, to create a warm and comfortable environment for the newborn piglets and a large environment. .

2. Feeding management of newborn piglets: The piglets are kept at a constant temperature of 38.8 °C in the uterus of the sow. The subcutaneous fat of the newborn piglets is less resistant to cold, that is, the temperature in the incubator in the first week of the piglet is kept at 34-36 ° C, and every two afterwards. The temperature dropped to 1 °C, and the temperature in the weaning incubator was controlled at 26-28 °C.

3, 5-7 days after the birth of the piglet to do the feeding and training work. The first is to reduce the diarrhea of ​​the suckling pigs in about 15 days; the second is to increase the weaning weight of the piglets; and the third is to reduce the stress of the weaning diet of the suckling piglets.

2. Feeding management points for weaning and nursery piglets

1, piglet's digestive system, the body's regulatory function of nerve and immune systems are not yet at weaning improve growth, the reduction of various stress factors are most important.

2, the mother not split split weaning Aberdeen, i.e., off the sow, piglets stay in the same ring or 7-10 days over the bed capacity feeder, reducing the stress factors of environmental changes; i.e., reduced early fed the diet should be changed shock factor; to control the temperature of the incubator at 26-28 ℃, ambient temperature was maintained pens 22 ℃, and the stress factors reduce the temperature difference; stress factors affection only.

3, added to drinking water three days before the weaning tragacanth polysaccharide powder cod liver oil + vitamins + powder + ORS, once every 10 days, and can effectively reduce various stress response, improve the ability of the immune disease of weaned piglets, to avoid dehydration resulting from diarrhea .

4, weaning feed the less many meals, 4-6 meals a day, piglet diarrhea is not a standard diet, gradually increasing dietary 7-10 days. The fast-growing diet needs of weaned piglets are: body weight × about 4-5% = diet for weaned piglets, one of the formulas for diets for piglets within 30 kg of body weight.

5, 10 days later transferred to the nursery, the environmental temperature of the nursery house can not be lower than 22 ° C ~ 26 ° C, it is recommended to prepare the insulation board on the nursery bed to let the pigs sleep, if the pad is covered with grass, must be replaced daily, to ensure The bedding is dry; in the case of sunny and windless weather, the nursery house should have a suitable density and should not be too dense.

Third, the breeding management points of fattening pigs

1. When the general nursery group is transferred to the fattening house, the body weight is about 25-30kg body weight, but the biggest drawback of the autumn and winter spring nursery transfer fat house is the temperature difference, which is the most likely to cause respiratory diseases, so the temperature of the fattening house should be controlled at 20 -24 °C, in the transition period, it is recommended to place bedding in the enclosure, reduce the heat of the pig body caused by the cold cement floor, and reduce the infection of diarrhea, respiratory tract and flu during the transition period of the group stress. .

2. The padding of the pens is changed daily and kept dry. The breeding density of the pigs should be suitable for the growing demand of pigs. The density should not be too large. The first one will cause the damps to be wet, and the poor ventilation will cause respiratory diseases and cause The uneven size of the herd growth cannot reach all in and out.

3, followed by the growth rate of the herd, can be in the pig group weight of 50-60kg, the ambient temperature of the pen house can be maintained at 18-20 ° C, the minimum can not be lower than 15-16 ° C, otherwise it will lead to the conversion rate of feed nutrition Reducing, reducing the immune resistance of the herd, inducing infection of various diseases, prolonging the growth cycle of the herd, and reducing the efficiency of raising pigs.

4. Feeding management of male and female sow herds

1. The best breeding environment for breeding males and sows is 18-22 °C, and the minimum temperature should not be lower than 15-16 °C. Keep the pens dry and clean.

2. Although the ambient temperature is important, it cannot be ignored. In the cold autumn, winter and spring, they also sleep on the cold concrete floor. At the same time, they consume a lot of heat from the body to resist the cold temperature of the ground, so it leads to autumn and winter. Diseases such as male and female sows, hypothermia, miscarriage, stillbirth, dystocia, no milk, no estrus, etc.

V. Nutrition and vaccine prevention should pay more attention to

1. The annual autumn harvest season is also the alternate season of new corn. The new corn is greatly harvested. The shortage of Chen corn is the main source of energy for pig feed nutrition, forcing the majority of farming friends to use new corn, but The moisture content of the new corn is too high, and the nutrients such as energy and amino acids are not up to standard, but the various mycotoxins are high in excess, so the pigs tend to cause disease after feeding.

2, according to the climatic temperature in autumn and winter and the use of new corn, the author recommended a program for the majority of breeding friends: First, add 1-2% oil to the diet of the herd to supplement the shortage of new corn energy; At the same time, adding 5% glucose powder to the diet can assist the liver's detoxification function and also supplement energy. Third, adding 0.3-0.4% baking soda to the diet can assist the kidney's venting function to detoxify; The fourth is to add 0.2% of multivitamins to the diet to supplement the lack of nutrients in the new corn, improve the immune resistance of the herd, promote the health of the herd, and improve the efficiency of pig raising.

3, each farm has an immunization program suitable for this field, must be strictly implemented and operated, remember to freeze the vaccine when immunization, remove the refrigerator to room temperature, or put 15-20 ° C water, until the temperature of the vaccine is close to the water temperature , then dilute the injection of immunization, in order to facilitate the immunization injection to reduce the temperature difference stress response and improve the vaccine immune efficacy.

Sixth, drug health care

According to the season and the epidemic situation of the field and the local epidemic situation, develop a drug health plan and add feed on time.
