The core tips: The main causes of premature sows, miscarriage, and stillbirths of pregnant sows are: First, nutritional deficiencies; second, feeding and management improper feeding of odor-stimulating or moldy feeds causes abnormalities in sows. Should take appropriate measures to avoid.
The main causes of premature sows, abortions, and stillbirths of pregnant sows are: First, nutritional deficiencies, such as low feed nutrient levels, lack of vitamin E, vitamin A, resulting in excessive weight loss of pigs caused embryonic early death; Second, improper feeding management, such as Insufficient breeding density, disparity in body weight caused biting and fighting, the floor of the pig house was slippery and prone to slipping, etc.; third, feeding with irritating odor or moldy feed and winter feeding of frozen feed; fourth, no timely injection of parvovirus. Japanese and Japanese encephalitis vaccines.
Preventive measures to identify the reasons, if the nutritional level is too low, we must promptly adjust the feed formula and feeding amount to prevent pigs from being too thin. The supply of vitamins must be complete, and the amount must be sufficient. When feeding a compound multivitamin, it should be supplied at 1.5 times the normal amount. It is strictly forbidden to feed with irritating odor or moldy feed, and use warm water in winter. The female pigs were injected with parvovirus and Japanese encephalitis vaccine as required. The injection method consisted of a parvovirus vaccine injection of gilts and reserve boars one month prior to mating, and a sow injected two weeks after delivery or before mating; The boar is injected once every six months. Strong immunity was produced 14 days after the injection of the vaccine, and the immunization period was 6 months. Japanese encephalitis vaccine is administered to reserve males and sows at the end of April to early May every year. The first-born sow must be injected, the second-born sow should be injected as much as possible, and no more than three children can be injected.
Sow milking technology:
Feeding more green-breed sows that stimulate lactation During lactation, besides feeding palatability, protein-, vitamin-, and mineral-rich feeds, feeds that stimulate lactation should also be fed. For example, the sugar beet roots and leaves, raw potatoes, and ramie are all good feeds.
Fermentation Fermentation When yeast is used for fermentation, starch diets should be appropriately increased to allow more yeast to grow and have aroma and sweet taste, which can stimulate the appetite of pigs, increase metabolism, and promote milking.
When using traditional Chinese medicine to promote stomach milk, general sows less milk or lack of milk, showed poor appetite, preference food and anorexia, it must use stomachic drugs to eliminate this phenomenon, while the application of drugs with obvious milking effect. Can use 40 grams of Vaccaria, 30 grams of wood, Du Honghua 30 grams, 50 grams of Six Divine Comedy, Jing San 30 grams, 20 grams of red peony, mixed with water, Jianzhi, a daily dose, taking 2 times, and even serving 2 ~ 3 days.
Use small fish, shrimp soup in the early period of sow lactation, using small fish, shrimp soup, fed into the feed, you can significantly increase the amount of milk, the general can be expressed after the second day.
Feeding the baby's clothing During the sow delivery season, the sow's placenta is collected. When the sow is delivered, washing the soup and feeding the pig also increases the milk yield.
