Pregnant sow special-purposed bioactive feed additive, premix, and batch

Abstract

The invention discloses a pregnant sow special-purposed bioactive feed additive, a feed premix, and a feed batch. The feed additive is prepared through the steps that: (1) a Chinese herbal medicine is prepared into Chinese herbal medicine powder, wherein the powder comprises the raw materials of, by weight: 15-30 parts of Mongolian milkvetch root, 6-15 parts of ligusticum, 10-25 parts of pilose asiabell root, 5-20 parts of largehead atractylodes rhizome, 5-20 parts of licorice root, 15-30 parts of immature tangerine fruit and dried tangerine peel, 10-40 parts of malt, 6-15 parts of Chinese pulsatilla, 8-20 parts of prepared rehmannia rhizome, and 16-40 parts of Szechwan lovage rhizome; (2) 15-20 parts by weight of a bioactive probiotics fermentation broth is uniformly mixed with 15 parts by weight of silicon dioxide; the mixture is subjected to low-temperature drying, such that a bioactive probiotics solid powder preparation is prepared; (3) 90% by weight of the Chinese herbal medicine powder obtained in the step (1) is uniformly mixed with 10% of the bioactive probiotics solid powder preparation obtained in the step (2), such that the feed additive is obtained. When the additive is used for feeding pregnant sows, healthy developments of fetuses in the mothers can be promoted. Also, pregnant sow miscarriage, stillbirths, mummified pig, postnatal hunger strike, mastitis, endometritis, and the like can be prevented. With the feed additive, piglet vitality and birth weight can be improved.

Description

technical field [0001] The invention belongs to the field of livestock and poultry feed, in particular to a special bioactive feed additive for pregnant sows, a preparation method thereof, and a premixed material and a batch material containing the same. Background technique [0002] The feeding of sows is one of the cores of the farm, and the health status of pregnant sows directly affects the efficiency of the farm. [0003] In recent years, the improvement of breeding technology has greatly improved the reproductive performance of sows, and the litter size is increasing. However, the ensuing problems are also very prominent, such as sow abortion in the first trimester, stillbirth and mummified fetus in the second trimester, late pregnancy, constipation, emaciation, jaundice, anemia, rough hair, etc. Inflammation and endometritis, that is, the postpartum "triad syndrome" of sows, delays estrus or no estrus after weaning, reduces the reproductive performance and service li...
