Body temperature monitoring In the isolation and rearing stage, the body temperature of the breeding pigs needs to be monitored, and the breeding pigs of each unit are sampled according to the species and sex. The number of sampling per unit is 6 (about 10% of the number of the unit breeding pigs) so that the status of the breeding pigs can be known in time. , found that the situation can be treated in a timely manner.
Breeding pigs control the watering of pigs that have just entered the isolation house and give the pigs only a small amount of feed after 12 hours. In the isolation and rearing stage, the feeding amount of breeding pigs should be gradually increased and finally reach normal, and glucose (additive amount is 5%) and electrolyte multidimensional (addition amount is 1 mg/kg) need to be added to the feed, and the adding time is 3-5 days.
When the breeding pigs control diarrhea, they need a process of adaptation to the new environment when they arrive at the isolation room. Therefore, diarrhea often occurs. By controlling the amount of feeding pigs and increasing drinking water, diarrhea can be quickly controlled. (Diarrhea, constipation, skin red spots, cough, fever, etc. are all normal stress responses).
Disinfection measures
1) Disinfection: Disinfect pigs once a day.
2) Use of disinfectant: The type of disinfectant can be selected from the "Yasheng-30" produced by Shuo Teng, a "clean farm" produced by Shanghai Peste (main components: Povidone-iodine) and "Jinyi-Poison "(The main component: compound iodine solution); Disinfectant dosage is 0.3L/m2, change once a week.
The control room for the air quality of the pig house should be kept clean and dry. It should be cleaned at least once a day and ventilation should be adjusted according to the external climate. By adopting the above measures, the harmful gas concentration can be effectively reduced and the air quality of the pig house can be improved.
The control of the pig house temperature It is better to control the temperature of the housewife between 18-20°C.
The introduction of spare pigs in the training of the introduction of reserve pigs carefully training, and ultimately the formation of fixed-point drinking water, fixed-point rest, fixed-point excretion of urine good habits.
Timely Measurement and Matching When the weight of the introduced breeding pig reaches 85-115 kg, the performance of the breeding pig must be determined. The main measurement indicators include the age at the time of 100 kg body weight and the back body thickness of the living body. The measurement results are then entered into relevant software for application of the BLUP method. The reserve pigs were evaluated. When the spare pig weight exceeds 100kg, the estrus status of the reserve pig must be queried and recorded every day so that the reserve pig can be bred timely when the body weight exceeds 125kg, the second or third situation, and the age is more than 7.5 months. Play breeding performance of breeding pigs.
