Natural vegetable preparation for promoting heat of dam and preparing method thereof

Abstract

The invention discloses a natural vegetable preparation for promoting heat of a dam. The natural vegetable preparation consists of the following materials according to the parts by weight: 1-3 parts of almond shell extract, 1-4 parts of pine extract, 2-5 parts of dandelion extract, 2-6 parts of asiatic plantain herb extract, 3-6 parts of leonurus extract and 3-5 parts of carriers. A preparing method of the natural vegetable preparation comprises the following steps: extracting pine, dandelion, almond shell, leonurus and asiatic plantain herb respectively; and the prepared dry powder and the carriers are mixed and stirred by proportion under the normal temperature and normal pressure to obtain the natural vegetable preparation for promoting the heat of the dam. The invention has the advantages that the natural vegetable preparation helps the heat of the dam, promotes the growth of an ovary and the secretion of ovum and improves the fertility rate, the propagation rate and the farrowing rate of replacement sows.

Description

technical field [0001] The invention relates to a natural plant preparation for promoting estrus in female livestock and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] Now to evaluate the operation of a pig farm, it mainly depends on the number of piglets provided in a sow year or the number of fattened pigs in a sow year. Whether the sow can be in normal estrus and timely mating is the key to the success of the pig industry. The common reasons why sows are not in heat at present include: (1) congenital factors: mainly physiological defects and genetic defects, such as underdeveloped reproductive organs, hermaphrodite pigs, abnormal secretion of hormones, etc. In addition, the existence of seasonal reproductive inferior genes may also cause seasonal sows to be in estrus; (2) caused by infectious diseases: Eperythrozoonosis of pigs, porcine reproductive and respiratory disease syndrome, porcine pseudorabies, pi...

Problems solved by technology

In addition, the existence of seasonal reproductive inferior genes may also cause seasonal sows to be in estrus; (2) caused by infectious diseases: Eperythrozoonosis of pigs, porcine reproductive and respiratory disease syndrome, porcine pseudorabies, pig cloth Some diseases such as bacillosis, Japanese encephalitis virus disease, parvovirus disease, chlamydial disease, etc., can lead to poor reproductive development of pigs, so that the pigs do not go into estrus or the estrus is not obvious, thus causing reproductive obstacles; (3) due to improper feeding management : If irregular artificial insemination causes damage to the uterine mucous membrane, sows are not in estrus; (4) Obstetrical diseases of sows can also cause anoestrus
