Feeding technique of binary sows

Binary sows refer to the sows produced by crossbreeding between Landrace boars and Landrace sows or between Landrace boars and Landrace sows, which have strong adaptability, tolerance to rough feeding, high litter yield and good motherhood, and can make full use of the characteristics of excellent lean meat type pigs, such as fast growth, good fattening effect and high lean meat rate, which can quickly improve the lean meat rate of commercial pigs. let's take a look at the feeding technology of binary sows.

Feeding technique of binary sows

1. Drinking water: clean drinking water should be provided to avoid diarrhea caused by drinking sewage or urine.

2. Grouping: when adjusting circles and grouping, groups should be divided according to gender, individual size, eating speed and so on. Weaned piglets should be allowed to maintain sufficient exercise time outside the pen, and the inside of the pen should also be clean, dry, warm in winter and cool in summer, and adjusted for excretion in a fixed place.

3. Feed: (20-60 kg) corn 53%, fine rice bran 10%, high quality fish meal 2%, soybean meal 16%, wheat bran 15%, calcium hydrogen phosphate 1.5%, stone powder 0.23%, salt 0.19%, additive 2.08%.

4. Management: to create a comfortable small environment, weaned piglets must be sunny, warm, clean and dry. Piglets should be thoroughly cleaned, thoroughly disinfected and bedded before entering the pigsty to create a comfortable environment.

5. Density: if the population is too large or the area of each piglet is too small, if there are not many troughs, it is easier to cause competition among piglets, resulting in insufficient rest and insufficient feed intake, thus affecting the development of piglets. The average area of each head is 0.5-0.8 square meters, and it is suitable for each group to be about 10 square meters.

6. Heat preservation: the climate in northern winter and early spring is cold, pigs are especially afraid of cold, often pile up to sleep together, squeeze each other, easy to crush, crush piglets, and easy to get sick, seriously affecting the growth and development of piglets. Therefore, attention must be paid to the cold protection measures of the enclosure, and warm rings and plastic sheds can be built to raise weaned piglets if possible.

7. Deworming: subcutaneous injection of 1% ivermectin 400 micrograms per kilogram of body weight at 50 to 60 days of age and, if necessary, at 90 to 120 days of age.

Immunization procedures in pig farms

1, 7-day-old injection of mycoplasma pneumoniae attenuated lyophilized vaccine (not used in pig farms where the disease has been purified).

2. 2 ml polyvalent inactivated vaccine of edema disease of piglets was injected intramuscularly at 15 days old.

At the age of 3 and 20 days, 4 doses of attenuated classical swine fever vaccine were injected intramuscularly.

4. Inactivated vaccine of PRRS (positive pig farm) was injected at the age of 30 days (used according to the instructions).

5. At the age of 35 days, choose inactivated foot-and-mouth disease vaccine (use according to the instructions).

At the age of 6 and 40 days, one dose of cold vaccine (live vaccine of attenuated Salmonella cholerae C500 strain of porcine cholera) should be injected intramuscularly or orally.

At the age of 7 and 56 days, 4 doses of attenuated classical swine fever vaccine (enhanced vaccine) were injected intramuscularly.

At the age of 8 and 60 days, 1 dose or 4 oral doses of Streptococcus suis attenuated strain freeze-dried live vaccine were injected subcutaneously or orally.

Instructions on the prevention of foot-and-mouth disease

1. In areas threatened by foot-and-mouth disease, type O oil emulsion inactivated vaccine of foot-and-mouth disease shall be injected into pigs of more than 50 kilograms, 2 milliliters of 25 kilograms of pigs and 1 milliliter of 10-25 kilograms of pigs.

2. Inactivated vaccine or attenuated vaccine of porcine transmissible gastroenteritis epidemic diarrhea in October every year.

Precautions for foot-and-mouth disease

1. Before and after the use of the vaccine, attention should be paid to the effect of the drugs used on the immune effect of the vaccine. Special attention should be paid to immunosuppressive drugs and antimicrobial drugs that can kill and inhibit the vaccine.

2. Subcutaneous or intramuscular injection of 0 2-1 ml epinephrine per head in case of allergy, and 10 times dilution if intravenous injection

3. Vaccine immunization should usually be carried out in the healthy state of pigs, and the immunization procedure is often adjusted by many factors such as the health status of pigs. Adjust the immunization procedure under the guidance of a veterinarian. Classical swine fever and foot-and-mouth disease should be forcibly immunized by the state, and the vaccine can be collected directly from the local veterinary prevention station or asked to be injected free of charge.

4. In order to make the vaccine work better, effective management measures must be taken to reduce the pathogenic microorganisms in the environment, but this is only a guide, and each farm should be adjusted according to the disease status and existing problems of their own pig farms.

5. Lactation is a key link. In order to reduce the chance of piglets being infected by sows, isolation early weaning or drug early weaning techniques can be used to wean piglets within 4 weeks. The guidance is as comprehensive and detailed as possible, but not every pig farm or pig farmer must follow it.
