Abstract
The invention provides a premixed feed for protecting health of sows and piglets. The premixed feed comprises vitamin E, vitamin C, glucose, a mycotoxin adsorbent, an astragalus extract, a codonopsis pilosula extract, probiotics, an antioxidant enzyme preparation, selenium yeast, ferrous glycinate, soy isoflavone and a yeast extract. The prepared premix feed is good in palatability, can effectively improve the appetite of the sows, increase the feed intake of the sows, reduce the loss of dorsal fat, protect the intestinal health of the sows, reduce the occurrence of constipation, improve the immunity of the sows, reduce the stress response of the sows, improve the conditions of lacrimal spots and dead skin of the sows, protect the health of the sows, and improve the breeding potential of sows; the time from weaning of the sows to re-estrus is shortened, the weight of newborn piglets is increased, sufficient milk of the sows is guaranteed, lactation is promoted, the growth speed of the piglets is increased, and the overall production performance and disease resistance of a pig farm are improved.
Description
technical field [0001] The invention relates to a premixed feed for protecting the health of sows and piglets, a preparation method and its application in feed for lactating sows, belonging to the technical field of feed. Background technique [0002] my country is the largest pork consumer in the world. From 2010 to 2018, the annual consumption of pork exceeded 50 million tons. Pork is the main source of meat for Chinese residents and plays an important role in the dietary structure of Chinese residents. At present, in the process of raising pig farms, due to environmental, management, high yield, nutrition and other issues, a large number of oxidative stress reactions will occur in lactating sows, and a large number of free radicals will be generated, which will destroy the redox balance of the body and make the pigs in sub-health status, low immunity, tear spots, dead skin, constipation, abnormal estrus after weaning, etc. [0003] As China's feed "ban on antibiotics" be...
