Feed additive used for milk secretion promotion and estrus of sows and preparation method thereof

Abstract

The invention discloses a feed additive used for milk secretion promotion and estrus of sows and a preparation method thereof. The feed additive includes the raw materials of: menyanthes trifoliate, potentilla anserina, valerian, radix pseudostellariae, pteridium squilinum, silene aprica, lucid ganoderma, saussurea involucrata, roots of codonopsis lanceolata, jujube, ficus stenophylla, metaplexis japonica, flos farfarae and panax notoginseng, and also can comprises, preferably, jasminum laurifolium, roots of chicory, herbal biondia henryi, dioscorea zingiberensis, flos pyrethri tatsienensis and vitis flexuosa. The feed additive can satisfy nutrient requirement of milk secretion promotion and estrus of sows, and can improve function of digestion system and increase the appetite of the sows. Sows fed on a feed with addition of the feed additive are improved in estrus rate, wherein milk contents of colostrums and ordinary milk are improved. The feed additive can enable breast to be plump and promote normal development of nipples, can ensure normal growth of mammary gland and other organs in body of a sow and significantly reduces disease probability of the sows.

Description

technical field [0001] The invention relates to a feed additive for sows, in particular to a feed additive for sows to promote lactation and estrus and a preparation method thereof. Background technique [0002] Pregnant sows, whose metabolic rate is much faster than other pigs, often encounter the problem of insufficient milk, resulting in stunted or dead piglets, which bring serious economic losses to pig farmers. There are many reasons for postpartum hypogalactia or agalactia in sows, such as malnutrition, thinness, frailty, and decreased physiological functions of pigs; overfat sows, breasts are filled with fat; sows are bred too early, and mammary glands are hypoplastic; It is necessary to take timely measures to promote lactation for lactating sows. Pig farmers inject reproductive hormone drugs to sows after mating. Although it can effectively increase the number of litters, long-term injection of reproductive hormones will cause hormone residues in meat, which has ...
