Piglet nursery is an important feeding stage for piglets from the successful transition from weaning to feeding. Good piglet conservation is the key technical measure to improve the piglet rearing rate and economic efficiency. Therefore, it is particularly important to promote the comprehensive care technology for piglet conservation in large-scale pig farms. In the long-term grass-roots technology contracting process, the author conducted several useful explorations of piglet conservation technology and also summarized the practical experiences that can be used for reference.
Large-scale pig farms are equipped with infrastructures such as warming room, nursery house, farrowing bed and nursery bar. In the production practice, piglet conservation comprehensive health care technology can be adopted from the piglet weaning to the rearing stage of the nursery.
1, the original column to stay in the same nest care
When suckling piglets are 18 to 20 days old, they should be weaned in time and transferred to the nursery stage as the sow’s lactation and milk quality decline. During weaning, the sows should be rushed out of the farrowing bed and the piglets should be kept for 1 to 2 days in order to reduce the offspring's absence, loneliness, and environmental stress. After weaning piglets are transferred to nursery stalls, it is best to transfer the litters to the same nursery stalls, not to replenish the herds, in order to prevent piglets bullying, bullying and catching each other.
2, timely feed, do a good job in health care
At 10 days of age, the suckling piglets can be fed and bred to activate the gastric mucosal protein and various enzymatic agents to increase the stomach volume. After the weaned piglet is transferred to the nursery bar (high bed piglet nursery bar) for 3 to 5 days, use the time the piglet enters into a sensational diet. In the nursery phase, enter gut peptide 1 (oligosaccharide, Bacillus major) in time to take less feed. Diligent feeding methods, eat less and more meals, feed 7 to 5 times a day, with the increase of the age, gradually reduced to feed 5 to 3 times a day, not only to prevent food-borne diarrhea in nursery piglets, but also to prevent hunger Pull it. In order to adapt to the digestive physiology of piglets, it is better to adopt the feed method of wet mix. The wet mix is ​​pre-mixed and the method of time fermentation can improve feed utilization, enhance palatability, and reduce feed. waste. At the same time, piglets electrolytes, white sugar, vitamin C or antibiotics and other drinking water preparations are used to promote healthy growth and development of piglets. Practice has proved that the use of gut peptide Jin 1 piglets, anti-stress ability was significantly enhanced, the risk of diarrhea in piglets can be reduced by 80% to 90%.
3, strengthen program immunization, do a good job of preventing deworming
The piglets were given intramuscular injection of swine fever vaccine on days 2 to 3 after the piglets were transferred to the nursery (ie 21 to 23 days old piglets), then intramuscularly injected with Pasteurella multocida and erysipelas pigs at 26 to 28 days of age. Vaccine, a paratyphoid vaccine injected intramuscularly at 35 days of age. When the vaccine is injected, clear weather should be selected and it should be carried out 2 hours after feeding. During the injection of vaccine, piglet electrolyte + vitamin C + white sugar solution should be supplied to avoid injection stress and vaccine reaction. At the same time, regular preventive deworming and castration work should be done in a timely manner.
4, adjust the pig house temperature, keep a good ventilation
After the piglet is transferred to the nursery, the piglets must lay a certain range of cushions in the lying field to prevent the piglets from lying on the bar, causing diarrhea and cough and other diseases. The temperature of the pig house should be kept above 25°C. With the increase of the age, the temperature of the pig house should be adjusted timely, and the temperature should be reduced by 2~3°C per week. In the summer, it is necessary to pay attention to the prevention of heatstroke and in the winter, it is necessary to do well in cold insulation. At the same time, keep the pig house clean and dry, with good ventilation and fresh air, so as to create a suitable growing living environment for the piglets.
5, adhere to scientific management, do a good job of training piglets
After the piglet is transferred to the nursery, it is an important stage for the piglet to move from a semi-parasitic life to an independent life. There are no laws for eating and drinking. Therefore, from the beginning of the piglet transfer, the husbandry and management personnel must carefully tune the piglets so that the piglets can eat and drink Lazard to develop a “four-positioning†law of living. To keep the piglets warm and warm, a 150 is installed above the pig stall. ~250W infrared light bulb to increase the temperature of the pig house to ensure safe wintering piglets. In addition, the use of night-time pigs in winter to allow free movement of piglets is also a good way to enhance the physical fitness of piglets. In this way, through scientific feeding management. Not only can piglets develop good living patterns, but they can also speed up the growth and development of piglets.
6, do a good job of environmental disinfection, control of disease
Before the piglets are transferred to the nursery, disinfection methods such as fumigation and spraying are used for the nursery and nursery. The sterilizing, decontamination, and non-hazardous treatment of the filth, feeding utensils, nursery bars, and backings of the nursery will be carried out, and odors will be removed after 1 to 3 days of ventilation. Transfer the piglets to the nursery. For nursery houses with large areas and many nursery columns, according to the situation, the disinfectant with less odor, such as double-effect quaternary ammonium salt and steroids, can be used for brush disinfection. In the subsequent conservation process, disinfection is performed 1~ weekly. 2 times. When disinfecting, two or more disinfectants can be used alternately. At the same time, keepers must observe pig population status at any time, pay attention to epidemic monitoring and timely control of the epidemic.
After adopting the above technical measures, the survival rate of nursery piglets after nursery and rearing for 40 to 45 days can reach 95% or more and the average head weight can reach 15 to 20 kg. At this point can be transferred to the fattening stage.

What is the piglet nursery rate?
The survival rate of piglets in the nursery period is referred to as the childcare rate. The nursery period is when the piglet is weaned to an 8-week-old age. This is the time before the breeding period is before the lactation period.
How do you manage and how high piglets survive?
Suitable fence. The delivery room design should be reasonable, try to install a nursery bar frame, while setting up piglet nursery feeding room, so that the mother and child to sleep separately, to prevent the sow crushed dead piglets. Piglets produced by large, bulky, unresponsive sows and crossbreeding pigs that are not well protected need to be doubled.
Giving piglets a warm, dry, hygienic and thirsty environment can reduce the death of piglets by nearly 50%, and effectively accelerate the rate of weight gain. Piglets are required to have 32-35°C at the age of 7-days, 30-32°C at 8-14 days, and 28-30°C at the age of 15 days. In the cold days, stoves or infrared lamps should be used to increase the indoor temperature.
Shiitake is known as the "Queen of Plants" and is rich in amino acids and a lot of nutrients that are good for the human body. According to analysis, every 100 grams of fresh mushrooms contain 12 to 14 grams of protein, which is far more than the protein content of ordinary plant foods. In addition, it is an excellent source of calcium, phosphorus, iron, zinc and other micronutrients.
