Problems solved by technology

Some scholars (the effects of hormones and Chinese herbal preparations on abnormal estrus in sows and comparative experiments, Huang Zhuan, Chinese Animal Husbandry and Veterinary Medicine, No. 7, 2006) used Chinese herbal medicines to treat sows' anestrus. High dosage, slow drug effect, serious waste and poor palatability, etc., which will cause pigs to eat less or refuse to eat, and the desired effect cannot be achieved.
[0005] Invention patent CN101869221B discloses a feed additive for improving the reproductive ability of sows. The additive includes 45-50% of Epimedium, 10-15% of Motherwort, 5-10% of Cuscuta, 5-10% of Angelica, and 3 ~5%, vitamin A0.3~0.5%, vitamin E1~2%, folic acid 0.5~0.8%, although these kinds of herbs can improve the reproductive ability of sows, but the effect is not obvious; higher cost
The particle size and diameter of the finished product are less than 10 μm (that is, more than 300 mesh), but the composition of the Chinese herbal medicine feed additive is complex and the cost is high

Embodiment 1

[0025] Adopt the preparation method of the feed additive that improves sow production performance of the present invention, get altogether 33kg of dry extracts, wherein 18kg of Guangdong Zizhu dry extracts, 6kg of motherwort dry extracts, 3kg of Rhizoma Cyperi dry extracts, and 2kg of Scutellaria baicalensis dry extracts . The above dry extracts of four flavors are crushed to a fineness of less than 80 meshes, mixed with an appropriate amount of auxiliary materials, such as cornmeal, etc., and packed separately to obtain a finished feed additive.

[0026] Using the feed additive prepared by the above method, the company conducted a feeding experiment on sows in a large pig farm in Luxi County, Pingxiang City. The sows were clinically healthy and had 2 litters. The breeding period was normal and the breeding period was basically the same (5 60 multiparous sows within days), there were 3 groups including control group, 1.5‰ additive test group and 2‰ additive test group, with 20...

Embodiment 2

[0028] The feed additive preparation method for improving sow production performance of the present invention is adopted to prepare the feed additive, and 31 kg of dry extracts are taken in total, including 20 kg of Guangdong Zizhu dry extract, 6 kg of motherwort dry extract, 3 kg of Cyperus cyperi dry extract, and 3 kg of dried Scutellaria baicalensis. 2kg of extract, the above four dried extracts are pulverized to a fineness of less than 80 mesh, and an appropriate amount of auxiliary materials is added to mix uniformly to obtain the finished feed additive.

[0029] The feed additive company prepared by the above method was tested in a pig farm in Xiangdong District, Pingxiang City. It was added to the diet of sows at a ratio of 2‰, and used for 7 days after delivery. The data was collected and analyzed through the test. The postpartum estrus time of the additive test group Shortened by 5.1 days, 86% of the estrus occurred 30-35 days after farrowing, and 21% of the control gr...

Abstract

The invention relates to a feed additive capable of improving sow productivity and preparation and using methods thereof, which belong to the technical field of feed additives. The feed additive capable of improving sow productivity consists of the following components in parts by weight: 16-25 parts of dry callicarpa Kwangtungensis extract, 4-8 parts of dry leonurus japonicus extract, 2-5 parts of dry rhizoma cyperi extract, and 2-4 parts of dry scutellaria baicalensis extract. The feed additive capable of improving sow productivity is prepared by the following steps: grinding natural plant extracts of callicarpa Kwangtungensis, leonurus japonicas, rhizoma cyperi and scutellaria baicalensis oin a mass ratio into fine powder, and adding proper amount of an auxiliary material to obtain a powder agent. The feed additive is capable of effectively improving sow immunity and sow productivity, and promoting healthy growth of piglets.

Description

technical field [0001] The invention relates to a feed additive for improving the production performance of sows and a preparation and use method thereof, belonging to the technical field of feed additives. Background technique [0002] The current epidemics of animal husbandry are mostly characterized by atypical viral diseases, bacterial diseases, mixed infections, and secondary infections, which have adverse effects on the healthy development of animal husbandry. In order to prevent and control epidemic diseases, it is quite common for farmers to widely use antibiotics or other synthetic drugs in the process of raising pigs. The overuse of antibiotics leads to enhanced drug resistance of pathogens, resulting in excessive drug residues, which seriously threatens human health and safety, and also restricts the development of pig breeding industry. At present, developed countries such as Europe and the United States have successively banned or restricted the application of ...
