Problems solved by technology

[0003] In order to solve the above-mentioned problems in the current industrialized pig farming, a large number of synthetic drugs have been used to improve the reproductive performance of sows. Although the use of these drugs has achieved certain results, the subsequent abuse of drugs has caused sows Phenomena such as body damage, drug residues, increased drug costs, and declining economic effects

Embodiment 1

[0016] Embodiment 1 Preparation of Physiological Regulator

[0017] Take by weighing 2.0kg of S. chinensis, 2.5kg of double kidney ginseng, 2.5kg of iron leech, 2.5kg of Xiangshiteng, 4.2kg of Dipsacus and 1.5kg of Angelica sinensis, pulverize, mix and decoct twice, and add water for the first decoction. 12 times the total amount of raw materials, heat and boil for 2 hours; add water 10 times the total amount of raw materials to heat and extract for the second decoction, keep boiling for 1 hour, combine the decoction, filter, collect the filtrate, and when the filtrate is concentrated to 70 ° C, mix with water The relative density of the concentrated solution is 1.10, add ethanol to make the alcohol content reach 80% (v / v), let it stand for 8 hours after stirring, filter, recover the ethanol from the filtrate and concentrate it to 90 ℃, and the relative density with water is 1.35 The thick paste is dried at low temperature and crushed to obtain.

Embodiment 2

[0018] Embodiment 2 Preparation of Physiological Regulator

[0019] Take by weighing 2.4kg of S. chinensis, 2.5kg of double kidney ginseng, 3.0kg of iron leech, 2.1kg of sycamore, 5.0kg of Dipsacus and 1.3kg of angelica, crush them, add water to decoct twice after mixing, and add water for the first decoction. 12 times the total amount of raw materials, heat and boil for 2 hours; add water 10 times the total amount of raw materials to heat and extract for the second decoction, keep boiling for 1 hour, combine the decoction, filter, collect the filtrate, and when the filtrate is concentrated to 70 ° C, mix with water The relative density of the concentrated solution is 1.10, add ethanol to make the alcohol content reach 80% (v / v), let it stand for 8 hours after stirring, filter, recover the ethanol from the filtrate and concentrate it to 90 ℃, and the relative density with water is 1.30 The thick paste is dried at low temperature and crushed to obtain.

Embodiment 3

[0020] Example 3 Preparation of Physiological Regulator

[0021] Weigh 1.7kg of sarcophagus chinensis, 3.2kg of double kidney ginseng, 2.4kg of iron leech, 3.0kg of cypress vine, 4.0kg of Dipsacus and 1.0kg of angelica, pulverize, mix and decoct twice, and add water for the first decoction. 12 times the total amount of raw materials, heat and boil for 2 hours; add water 10 times the total amount of raw materials to heat and extract for the second decoction, keep boiling for 1 hour, combine the decoction, filter, collect the filtrate, and when the filtrate is concentrated to 70 ° C, mix with water The relative density of the concentrated solution is 1.05. Add ethanol to make the alcohol content reach 75% (v / v). After stirring, let it stand for 8 hours, filter, and recover the ethanol from the filtrate and concentrate it to 90 ° C. When the relative density with water is 1.35 The thick paste is dried at low temperature and crushed to obtain.

Abstract

The invention discloses a physiological regulator for promoting sow to rut and a preparation method of the physiological regulator. The physiological regulator is prepared from the following Chinese herbal medicines in parts by weight through a water extract and alcohol precipitate method: 17-24 parts of trifid sopubia herb, 20-32 parts of goodyera brachystegia, 21-30 parts of neottopteris nidus, 21-30 parts of lanceleaf magnoliavine herb, 35-50 parts of teasel roots and 10-20 parts of angelica sinensis. The physiological regulator provided by the invention can remarkably shorten the time required by re-rutting of a multiparous sow and avoid the improper phenomenon that the artificially fed multiparous sow ruts in 7 days after ablactation, so that the non-productive days of the multiparous sow is reduced, and the sow-raising cost is saved.

Description

technical field [0001] The invention belongs to the technical field of physiological regulators, and in particular relates to a physiological regulator for promoting estrus in sows and a preparation method thereof. Background technique [0002] At present, the industrial pig raising method is gradually replacing the traditional free-range farming method and has become the main production form of my country's pig raising industry. Compared with traditional free-range farming methods, factory pig raising has greatly improved labor productivity, and at the same time standardized pig production management, making large-scale, assembly-line pig production possible. However, in the process of industrialized pig raising, most of the sows are raised in stalls, and the sows lack exercise for a long time. At the same time, the application of early weaning technology makes the sows be in a high-load production state for a long time, which makes the sows very prone to reproductive disor...
