Key points of feeding and management of fattening pigs related to fattening rate and benefit

Immunity of finishing pigs

1. Feeding and management of fattening pigs:

1. Physiological characteristics of fattening piglets: poor cold resistance. After leaving the mother, young pigs are sensitive to temperature. if they live in low temperature for a long time, it will not only affect the growth of young pigs, but also cause a variety of diseases. In the fattening stage, the food intake of young pigs increases, and there is rush or gluttony. If fed and managed properly, the cubs will grow rapidly and gain weight quickly. After weaning, young pigs are prone to infectious diseases, such as transmissible gastroenteritis, classical swine fever, atrophic rhinitis and so on, due to the loss of maternal antibody protection and the imperfect autoimmune system.

2. Preparation of fattening piglets before transfer: before the fattening pigs are transferred to the pigsty, the pigsty should be thoroughly cleaned and vacated for about one week, and then be raised reasonably according to the source, breed and habits of the pigs. After grouping, the number should be kept stable as far as possible, and the fattening pigs suffering from disease, excessive difference in weight and weak physique should be adjusted in time.

3. Preparation of fattening piglets after entering the house: in order to ensure that fattening pigs go out together and improve the utilization rate of pig houses, rational grouping should be started from the time of transfer, and continuous observation should be made to reduce the fighting phenomenon of young pigs, and special care should be given to weak and sick young pigs. Each fattening pig occupies an area of about 1 kilogram, which is reasonably adjusted according to the actual size of the pig house, and at the same time, it is properly adjusted according to the seasonal change, which is sparse in summer, usually about 10 in each group. Train them to have a fixed place to defecate, drink water and sleep. Breeders adjust the growth environment of fattening pigs according to seasonal changes. We should pay attention to ventilation and cooling in summer, keep warm in winter, keep ventilated, remove harmful gases and create a good growth environment.

2. Feeding and management of fattening pigs in the four seasons:

1. Spring Festival management: regular sanitary disinfection, which can be disinfected with lime and plant ash. First, clean the pigsty, sprinkle the adjusted disinfectant into the pigsty, the corner and the crack of the wall, and clean up the feces in time to keep the pigsty dry. With good vaccination and frequent occurrence of various diseases during the Spring Festival, we must do a good job in epidemic prevention.

2. Summer management: cooling and preventing heat. Cooling is the core of summer feeding and management. Sunshade nets can be installed at the top of the pig house. At the same time, cold water is sprayed on the walls or pig body to achieve the cooling effect. Do not spray pig head directly. In summer, you should choose more fresh, juicy and vitamin-rich feed. Clean up the pigsty in time. Keeping the pig house hygienic and sterilizing the pig house in time can reduce the prevalence rate of fattening pigs and ensure the growth and development.

3. Autumn management: sufficient feed should be stored for fattening pigs in autumn, and the fine collocation should be reasonable to meet the nutritional needs of finishing pigs. Autumn is the best fattening period for pigs, when the growth rate of fattening pigs is fast and the food intake is large. In the feeding method, the wet feeding method of raw meal should be adopted and fed regularly every day.

4. Winter management: in order to prevent infectious diseases, fattening pigs were vaccinated and dewormed before winter. Deworming is done once a year in spring and autumn with 2 courses of treatment each time. The pigsty should be repaired to protect against wind and cold. Properly increasing the number of fattening pigs can increase the temperature of fattening pig house, which is beneficial to the growth of fattening pigs.
