Giving full play to the maximum potential of lean-type breeding pigs and further improving the production performance of lean-type breeding pigs is a major factor in the economic benefits of raising pigs. To this end, the author summed up his own practical experience in production, comprehensively improved the environment, technology, management and other aspects, and put forward new measures to improve the lean-breeding pig breeding technology. Establish a new mode of delivery and production and create an ideal production environment for breeding pigs According to the number of sows produced in the whole field and the principle of balanced production, the number of weekly sow production is calculated, and the size of the delivery room and the nursery house are determined so as to achieve small-scale all-in and full-out, each with 10 to 16 beds. The excrement ditch is changed from the Sheopou Ming Ditch to the “pipeline†ditch in the house, avoiding the excrement ditch becoming the “impure†of the winter thieves, preventing the thieves from invading the pig body; using the “steep slope†concept to build the delivery room and the nursery house, that is, adding Large production bed, Aberdeen bed slope below the ground, with a 2 meter drop of 30 to 40 cm is appropriate, and the ground as smooth as possible so that there is no urine and water under the bed, reduce the humidity within the home: between the bed and the pig aisle stay 20 cm clearance. In order to artificially excrete. Minimize the number of flushing; ensure that the bottom of the bed more than 40 cm above the ground. Can effectively prevent the rise of moisture on the ground directly harm piglets. The new concept designed delivery room not only achieves all-in and full-out, avoids the chance of cross-infection, but also effectively reduces piglet diarrhoea caused by high humidity in the house and reduces the incidence of diarrhea in piglets. The average weaning survival rate of piglets is above 92%. Increased by 15 percentage points over the control group. Each sow can provide more than 4 commercial pigs. Realizing organic combination of small group rearing and single column positioning Single-column positioning is the most popular feeding method for pregnant sows in the domestic pig industry in recent years. Compared with the original small-group mixed feeding, it has the advantages of saving feeding area, single-pig constant material, and easy control of waterlogging. However, we discovered in the study that it has the disadvantage of being "fatal", especially for the lean-type hog which requires high management and feeding conditions. That is, the incidence of limb and foot disease is high and the difficult-to-yield rate is high, resulting in a high elimination rate of sows. Therefore, we complement each other and establish a comprehensive model of “single-definition and group-feedingâ€. That is, “one-column positioning†is carried out two months before the start of pregnancy, and is still fed to the prenatal period with “small-group mixed feeding†two months later. Each week, 2 to 4 heads. Through “double bindingâ€, the difficult birth rate decreased from 5% to 1%, a decrease of four percentage points: the limb and hoof morbidity rate was reduced from 4.8% to 1.4%, and the i point was reduced by four percentage points: the sow culling rate was reduced from 7.5% to 1.5%, a reduction of six percentage points, the effect is extremely significant (see Table 2 for the effect of feeding mode). Successful early weaning The success of early weaning is directly related to the effective utilization of sows and is an important part of improving the reproductive rate of lean-type breeders. The specific operation is as follows: (1) Postpartum must ensure that every piglet eats colostrum within 2 hours. (2) Fix the nipple according to the size of the piglet and the order of production, so that the weak front is strong enough to ensure uniform development of the nest. (3) Guaranteed adjustments within 7 days. The pig's milk is mixed into a thin paste and wiped on its mouth to enhance its sense of smell and sensation. Under normal circumstances, the material can be taken in 3-5 days, and it can be eaten in 7 days. (4) Use high-grade sucker feed to ensure adequate nutrition and reduce stress. (5) Do a good job of health care. That is, in the 3,7,21 days for three-pin health care, timely iron supplementation, selenium, water, and regular disinfection, do a good job of preventing epidemics. Reduce disease. (6) Control the temperature and absolutely avoid the temperature going up and down. Make the piglet in a relatively comfortable environment. Days 1-3, 32°C, Day 4, 30°C, Days 5-7, 28°C, Weeks 2-4, 25°C, Weeks 5-6, 20°C. (7) Feeding the original circle reduces stress. After the weaning, the sows are driven off and the piglet can be circled after one week. (8) Postpartum clean official sows. First of all, two oxytocins were injected to induce the lochia to be discharged as soon as possible, and then the normal streptozotocin was injected into the uterus to further remove the uterine lochia and prevent secondary infection. The incidence of metritis was reduced. The above eight comprehensive measures can ensure that weaning of piglets is advanced from 35 days to 21 days, and the sow return rate can be reduced from 20% to 2%, and the number of weaned piglets per sow is increased from 14 to 14% per year. 18 heads, raising sow productivity by 28.6% (see Table 3 for comparison of different weaning patterns). Do a good job of comprehensive prevention and control of epidemics Establish the idea of ​​"preventing stress and preventing combination". The first is to establish strict epidemic prevention procedures. In order to be targeted, epidemic disease testing should be conducted on the basis of the Animal Disease Control Center. Then according to each field, practical and feasible epidemic prevention procedures are established and strictly followed procedures. No deviations are allowed; the second is to adjust according to different ages, seasons, physiques, and production directions in a timely manner so as to be suitable for pigs; third is to purchase biological products approved by the State to ensure the concentration of plaques; and fourthly, to prevent the regular administration of drugs. To prevent secondary infections; Fifth, do a good job of disinfection and cut off the means of transmission: Sixth, keep abreast of the epidemic situation in the country and the surrounding areas. Be aware and take preventive measures. Seventh, harmless treatment of dead bodies, excreta, etc. reduces cross-infection. Resolutely eliminate the occurrence of epidemic diseases, especially diseases that cause sow reproductive failure, such as parvovirus, pseudorabies, blue ear disease, Eperythrozoonosis, etc., so as to ensure that the lean type breeder pigs have high reproductive rate, low incidence and mortality rate. Mining management potential. Humanity maximizes potential There is a jargon in the pig industry: “three-point technology, seven-point managementâ€. Management is the key to success or failure. Therefore, the following four principles should be adhered to in daily management: (1) Implement the "four modernization" management model that is "factory, standardization, scientific, and humane." While paying attention to scientific development, we should pay more attention to humanity in order to fully mobilize the enthusiasm and initiative of the staff in each position and reward them according to labor. Sihuan can increase the average annual labor compensation rate of the staff by more than 10%, while the overall efficiency of the farm can increase by more than 25%. (2) Feeding in strict accordance with scientific procedures to achieve "Excellent Excellent Treatment". That is to say, good breeds can only exert their maximum potential and give people the greatest return, according to scientific feeding procedures and scientific feeding methods. In production, we must not only resolutely put an end to the use of inferior raw materials, counterfeit drugs, and vaccine procurement, but also implement “nutrition catering†in accordance with different weights, ages, production directions, and uses of pigs to “quality and quantityâ€. Both meet their physiological needs and exert their maximum production potential. Resolutely put an end to the incidents that affect the performance of breeding pigs due to the use of poor quality, deteriorating feeds, and must not delay the prevention of epidemic and treatment events due to the use of “counterfeit and banned†drugs, and ensure the healthy and orderly healthy development of the farm. In addition, attention is paid to the control of farming environment. First, separate the cleansing path and the sewage path, and at the same time deal with the excrement in time, so that the excrement does not stay overnight in the field on the day to prevent repeated pollution and cross-infection. (3) Doing a good job of preventing summer heat and cooling in summer, especially for boars, must ensure that their sexual desire is strong, and sperms have high vitality and high density. (4) Deal with the relationship between winter insulation and ventilation, not only to ensure that there is a suitable temperature, but also to ensure that the ammonia concentration can not be too large due to obstruction too strict, induced respiratory diseases and other bacterial diseases. Therefore, a ventilation pipe and a ventilating cap should be installed at the top of the pig house. The ventilation pipe requires one meter of 3 meters and the opening direction must avoid the local main wind direction in the winter. It is necessary to smoothly discharge the ammonia without allowing the cold air to enter into the air.
