Abstract

The invention discloses a feed additive for fetus protection and miscarriage prevention of sows and a preparation method of the feed additive. The feed additive is prepared from, by weight, 40%-50% of cortex eucommiae extract, 20%-30% of milkvetch root extract and 20%-30% of pine tree extract. The pregnant sows are fed by following the traditional Chinese medicine compatibility principle and research of modern pharmacology on traditional Chinese medicine functions, combining the environment where the intensively-bred sows are located and the growth characteristics of the intensively-bred sows and taking agentia prepared from natural Chinese herbs as the feed additive on the basis of understanding and the treating principle of traditional Chinese medicine on the fetus protection and miscarriage prevention mechanism of the sows, therefore, the resistance of pregnant sow organisms can be improved, health can be promoted, the abortion rate is significantly decreased, the weight of neonatal piglets is increased, and the neonatal piglets are not prone to fall ill.

Description

technical field [0001] The invention relates to a Chinese herbal medicine feed additive in the technical field of medicine, in particular to a feed additive for sows to prevent miscarriage and a preparation method thereof. Background technique [0002] my country's pig industry is booming, and the high-density feeding of intensive pig farms leads to frequent occurrence of pig diseases. Chemical drugs such as antibiotics are still the first choice for the prevention and treatment of infectious and parasitic diseases. In the prior art, some drugs are often added to piglet rations to prevent pig diseases, which not only leads to the emergence of a large number of drug-resistant bacteria, but also causes the residue of chemical drugs in pork and its products, which brings great harm to public health and food safety. It is not in line with people's food consumption trend of "high quality, low drug residue, green and pollution-free". In order to meet people's consumption requirem...
