The survival rate of piglets is directly related to the economic benefits of farming. Therefore, all aspects of management should be done in the breeding process, especially the management of breeding pigs, suckling piglets and weaned piglets, so as to improve the survival rate of piglets. Therefore, today Xiaobian talks about measures to increase the survival rate of piglets.
First, the pig house insulation
1. Within 6 hours of birth, the breeding temperature should be controlled above 35 degrees, the temperature of 2-5 days is controlled within 34 degrees, the temperature of 7 days is controlled within 30 degrees, and the temperature of 8-14 days is controlled at 26 degrees. Within -28 degrees.
2. The development of various tissues and organs of suckling piglets is not mature, and the temperature regulation ability of the body is poor. If the temperature of the pig house is relatively low during this time, it will easily lead to diarrhea in piglets. When the temperature is low, the piglets will be frozen to death. Therefore, the temperature in the autumn and winter season should be controlled at 18 degrees or more. In the winter, it is necessary to add insulation facilities in the pig house, such as installing infrared heat lamps or heating plates. Of course, you can install 250 watts in the nursery house 40 cm from the bottom of the incubator. 175 watt infrared lamp for insulation.
3. In the process of piglet breeding, the traditional breeding mode should be gradually changed, from open farming to closed or semi-closed farming.
Second, timely eating milk, fixed nipples
1. The milk produced by the sow 3 days before delivery is colostrum. The colostrum is rich in immunoglobulin, vitamins and minerals, which can meet the nutrient requirements of the growth and development of suckling piglets. Breast-feeding piglets can gain immunoglobulin by eating breast milk and enhance their immunity.
2. Within one hour of birth of the piglet, the farmer should guide the piglet to eat colostrum and promote the growth and development of the piglet. At the same time, it is necessary to combine the body condition of different piglets and artificially help the piglet to fix the nipple.
3. When the breast milk is insufficient, the farmer should take timely measures to feed the suckling piglets to other lactating sows. For the insufficient number of lactating sows, artificial breastfeeding should be carried out.
Third, timely replenishment of mineral elements, reimbursement of feed supplements
1. Scientific iron supplementation: The demand for iron in the growth and development of piglets is relatively large. If the iron content of the sow in the lactating milk is low, it will cause iron deficiency anemia in the piglets, and the piglets will show poor mental state. Decreased feed intake, secondary infection with bacterial diarrhea, led to increased mortality in piglets. Therefore, iron preparations were intramuscularly administered to the piglets at 3 days of age and 10 days of age for iron supplementation.
2, selenium supplementation, copper supplementation: Insufficient copper in piglets, will affect the body's absorption and utilization of iron, causing iron deficiency anemia in piglets. Therefore, after the piglets are fed normally, 125 mg of copper is added per kg of feed to promote the growth of the piglets. If piglets lack selenium, it will affect the normal development of various organs of the body, and in severe cases, it will cause sudden death of piglets. Therefore, the piglets can be born 3-5 days old, and intramuscularly injected with 0.1% sodium selenite physiological saline 0.5ml. After the growth to 14 days of age, another intramuscular injection was performed, and 1 ml was injected per pig.
3. Early feeding: After the piglets grow to a certain stage, supplementing the feed early is beneficial to the growth and development of the piglets and promotes the improvement of the digestive system. Therefore, the feed can be fed early and fed with higher nutritional value. In general, piglets are supplemented with granular feed for suckling piglets at 5-7 days of age. The feed is applied to the piglets' nose and allowed to lick. After about 2-3 days of training, they can form eating habits.
Fourth, timely weaning
1. Early weaning of piglets can shorten the breeding cycle of sows, improve reproductive efficiency, and improve feed utilization and reduce piglet mortality.
2. When the piglets grow to 30 days old, the feed intake will gradually increase. At this time, the weaning work can be carried out step by step. The feed of the suckling pigs before weaning is continued for one week before weaning, and the transition is gradually completed in one week. Go to weaned pig feed.
