Prepare nursery piglets for raising pig farms Before the nursery pigs are allowed to enter the house, prepare piglet nursery houses, feed troughs, drinking fountains, heating equipment and lighting equipment, piglets, and commonly used drugs. The tanks, drinking fountains, etc. are thoroughly rinsed with clean water, then scrubbed with hot alkali water, rinsed with clean water, and then dried to dry; the piglet nursery is washed clean with clean water, and is dried and placed in a variety of utensils for nursery pigs, using formaldehyde. And potassium permanganate for fumigation, strict disinfection of doors and windows sealed 12 hours to 24 hours, then open the doors and windows for ventilation. Adjust the various equipments 12 hours before the nursery pigs go into the house and preheat them to 30°C to store the nursery piglets (afterwards, Sherwin reduces 3°C~4°C per week until it reaches 22°C). ~ 24 °C is appropriate). Relative humidity is 65%~75% Doing a good job in the environment control of piglets During the pig farms, the households should, according to their actual conditions, do a good job of environmental control in advance in order to find suitable environment for the conservation of the piglets and the ventilation and ventilation of the piglets. Effective approach. In case of fine weather and high temperatures, in addition to the timely opening of doors and windows to increase the natural ventilation and convection inside the piggery, a fan or fan can be allocated to the standardized pig house, and fans or fans can be turned on at the right time to maintain the temperature inside the nursery. 22°C~24°C, relative humidity 65%~75%. To ventilate and ventilate the piglets in the nursery, open doors and windows at a moderately sunny time and high temperatures. Open the doors and windows gradually from small to large, until the doors and windows are opened to a semi-open state. Farmers must not suddenly open doors and windows due to air pollution in nursery piglets, so that cool air can be directly blown into nursery pig houses. If room temperature suddenly drops in nursery pigs, it is easy to induce colds and other respiratory diseases in nursery piglets. . As far as possible to avoid the stress factors of nursery piglets The pig farmer should reasonably meet the ration according to the nutritional needs of the nursery piglets to provide a comprehensive and balanced feed for the nursery piglets to ensure the growth and development of the pigs. At the same time, in the management of nursery pigs, the nursery pigs should be placed in the public, mother, big, small, strong, and weak groups. The difference in the age of the same group of piglets should not be too great. It is better to control the piglets on the 7th. Within the age range, it would be better to use the original nest group to help stabilize the emotions of the piglets, reduce stress, avoid bullying and fighting each other and cause damage to the piglets; the rearing density of nursery piglets is controlled at 10 to 15 heads per field. It is advisable to reduce the number of pigs per pennant in the summer and increase appropriately in the winter to facilitate mutual heating of the piglets. At the same time, each piglet should have an activity space of 0.6 to 0.8 square meters; Internal drying, cleaning, sanitation, pig house, utensils and environment are regularly sterilized, pay attention to the insulation and ventilation in the pig house, reduce the concentration of ammonia in the pig house as much as possible to improve the air quality in the pig house, and implement conservation at the same time Feeding methods for all-in and out-feeding of piglets to reduce or avoid the chance of respiratory disease infection between the mother and herd of the piglet; minimize the number of times that the herd is transferred and mixed to reduce the stress of the nursery piglet factor. Establish a scientific and rational preventive drug use program for nursery piglets In view of the type and prevalence of respiratory disease in nursery piglets, pig farmers should properly formulate piglet immunization procedures and timely immunize piglets with swine fever and swine infectious pleuropneumonia. , Porcine atrophic rhinitis, Haemophilus parasuis, and Streptococcus avirulent bacteria or inactivated vaccines, in order to control the pathogenic factors caused by the respiratory disease in piglets to protect piglets, we should also develop a scientific and reasonable program for the preventive use of piglets in nursery. To prevent the secondary infection of exogenous and endogenous bacteria in nursery piglets. According to the production practice, the preventive drug plan is now recommended as follows: 7 days before and after sow giving birth, in order to reduce the amount of mycoplasma in the respiratory tract of sows and reduce the chance of early infection of mycoplasma in the farrowing room, 80% of the original net weight of the sow in the sow can be mixed with 125 grams of strong mold. 100g, or stir in 80% of the original net 125g, 12% Kefuping 2000g, sodium bicarbonate (baking soda) 1000g, or stir in 80% of the original net 125g, sulfisoxazole 500g 100 g of TMP and 1000 g of sodium bicarbonate (sodium bicarbonate) were fed continuously on sows 7 days before and 7 days post partum. Since piglets started at the age of 14 days, in order to control infections such as mycoplasma, streptococcus, and pasteurella, it is possible to mix 80% of the original net of 190 grams of aconitine, 150 grams of amoxicillin (pure powder) and 10 per ton of feed for piglets. % Colistin sulfate 1000 grams, continuously fed to the piglet refueling, or in the piglets per ton of drinking water mix 100% of the original 100 grams of the original net, 100 grams of amoxicillin, continued drinking every 7 days for 7 days until The piglets were weaned and refueled. In order to control the mixed infection of respiratory diseases and reduce the emergence of lean piglets, the piglet can be fed with 80% of the original rice and 80 grams of doxycycline and 120 grams of doxycycline per ton of feed to feed the piglet before and after weaning. Day, at the same time, add 150 grams of amoxicillin powder per ton of drinking water for 14 consecutive days, or mix 80% of the original 100 grams of the original and 80 grams of florfenicol to 80 grams per ton of feed. Feed 7 days before and after weaning. Piglets can also be implemented by referring to this drug prevention program during the transition.
Feed Additives are divided into microbial feed additives and Chinese herbal feed additives. Among them, microbial feed additive is a kind of microbial products that replace or balance one or more strains in animal ecosystem. In a narrow sense, it is a kind of microbial products that can stimulate the reproduction and growth of beneficial bacteria while resisting the growth of harmful bacteria. Microbial feed additives containing a large amount of beneficial bacteria (active lactobacillus, bifidobacterium, bacillus), compound enzyme, chelating peptide, mildew remover, etc., as the inside of livestock and poultry feed, can rapid reproduction, on the one hand, in bacterial metabolites and gut endotoxin inhibits the growth of other harmful flora, on the other hand, it formed the normal microbial flora in the host, Synthesize the main vitamins for the host, provide nutrition and prevent the invasion of pathogenic bacteria.
There are many different feed additives in category. There are vitamins, amino acides, antibiotics, Trace elements,Buffer feed, flavor agents, Hormonal additives, herbal additives etc.

Conservation management of nursery piglets
Nursery piglets are piglets from piglets after weaning to the rearing stage of growth and finishing. In the nursery period, the piglets have various physiological functions and immune functions. Since the piglets have been transferred from the lactation period to the nursery period, the feeding and management conditions have undergone major changes. The piglets are mainly fed with breast milk and supplemented with part of the feed. Feed feed all day long. In the nursery period, piglets are often exposed to diseases of the digestive tract and respiratory diseases due to primary infectious diseases, secondary infectious diseases, feeding and management, and environmental factors. This also causes losses to pig farmers. It is increasingly clear that except for the loss caused by the direct death of piglets, piglets that are chronically or insidiously infected not only affect their growth and development over a long period of time, but also give pig farmers a low feed conversion rate, slow growth and development, and The management of live pigs has serious consequences such as poor circulation. The pig farm households should adopt effective and comprehensive countermeasures in a targeted manner in order to achieve the effectiveness of preventing and controlling the respiratory diseases of piglets. Specifically, the following countermeasures should be taken:
