There are too many fine substances in most feeds, especially bean cakes, such as overfeeding, long-term lack of vitamins, trace elements and minerals, long-term decline, increased gastrointestinal burden, indigestion, small space and more exercise, which can also lead to diseases.
Characteristics of incidence of non-feeding in sows
Most sows are pregnant for 20 ~ 50 days or about one month before delivery, and a few sows are pregnant at different times.
Clinical symptoms of sow not eating.
Sows have normal or low body temperature (36℃-37.5℃), normal or slightly dry feces, less constipation, beaded feces, even defecation, less urine and red and yellow urine, depression, good sleep, normal breathing, obvious reduction in diet, and then develop into hunger strike without other obvious symptoms.
Prevention and treatment of sow not eating
1. Strengthen the feeding management of pregnant sows, especially perinatal sows. Pregnant sows should be fed special feed from big factories to prevent the feed from getting moldy, especially in the late pregnancy, and they must be provided with sufficient vitamins, minerals and other nutrients.
2. Strengthen environmental control and reduce cold stress. Piggery should pay attention to the adjustment of environmental temperature. In winter, we should conscientiously implement cold and warm measures to provide a suitable living environment for sows. High humidity and low temperature will bring great negative effects to sows.
3. Exercise properly. Sows can reduce exercise and keep quiet before mating 1-3 weeks and before labor 1-2 weeks to prevent accidental stimulation from causing miscarriage or premature delivery. However, in the second trimester of pregnancy (20 days after mating to pregnancy 100 days), sows should be given proper exercise and light, which is beneficial to the normal development of the fetus.
Antibiotics can control secondary infection according to different conditions, strengthen heart fluid, relieve major autotoxicity, enrich blood and stabilize fetus (delivery).
Management methods. Feed the sow with additives. Feeding pigs means feeding pigs with pig peptides, which are pure biological products and rich in small peptides, probiotics and special sow reproductive nutrition. The use of pig peptide can comprehensively improve the performance and appetite of sows.
In addition, most sows are kept in the positioning bar and cannot exercise normally; Especially in the third trimester of pregnancy, sows are unwilling to exercise for a long time, and the fetal volume becomes larger, which oppresses the digestive tract and reduces or relaxes the intestinal peristalsis, resulting in reduced food intake or no food intake for pregnant sows. Pig farmers should pay more attention.
