Embodiment 1

[0035] In the experiment, 10 healthy Duroc boars with similar body condition were randomly divided into 2 groups (divided into control group A and test group B), with 5 pigs in each group, 5 repetitions in each group, and 1 pig in each repetition. Under the same environment (about 25 degrees Celsius), one of them is set as the control group A, fed with the diet of the control group (i.e. the basal diet), and the other group is set as the test group B, fed with the diet of the test group (i.e. Add 1wt% additive in the basal diet), other feeding management is carried out according to the conventional method of the pig farm, the composition of the basal diet is 71 parts of corn, 19 parts of soybean meal, 4 parts of coarse bran, 2.5 parts of fish meal, calcium hydrogen phosphate 1.2 parts, 0.7 parts of stone powder, 0.4 parts of sodium chloride, 0.1 part of lysine, 0.1 part of choline chloride (the same below), the additives in the test group diet consist of: 80 parts of proanthocy...

Embodiment 2

[0040] In the experiment, 30 Duroc boars with similar body weight and reproductive performance were selected and randomly divided into 3 groups, namely control group A, heat stress control group B, and heat stress test group C, each with 10 boars , the control group A and the heat stress control group B were fed the basal diet without additives, the heat stress test group C was fed the test group ration (that is, adding 1wt% additive in the basal ration), the test group ration The additives in the composition are: 80 parts of proanthocyanidins, 120 parts of curcumin, 150 parts of lauric acid, 20 parts of vitamins, 30 parts of oregano oil, 30 parts of thymol, 20 parts of sodium butyrate, 100 parts of Chinese herbal medicine extract, 450 parts of carrier , in the Chinese herbal medicine extract, the weight ratio of rehmannia glutinosa, schisandra, raspberry, epimedium, medlar and honeysuckle is 4:8:10:18:20:40.

Embodiment 3

[0045] 30 healthy Duroc boars with similar body weight and reproductive performance were randomly divided into 3 groups, heat stress control group A, heat stress test group B, and heat stress test group C, each with 10 boars, The heat stress control group A was fed the basal diet without additives, the heat stress test group B was fed the test group diet 1 (that is, 1wt% additives were added to the basal diet), and the heat stress test group C was fed Feed the test group ration 2 (i.e. add 2wt% additives in the basal ration), the additives in the test group ration 1 consist of: 80 parts of proanthocyanidins, 120 parts of curcumin, 150 parts of lauric acid, 20 parts of vitamins, 30 parts of essential oil, 30 parts of thymol, 20 parts of sodium butyrate, 100 parts of Chinese herbal medicine extract, 450 parts of carrier, in the weight ratio of Chinese herbal medicine extract, rehmannia glutinosa, schisandra, raspberry, epimedium, medlar and honeysuckle 4:8:10:18:20:40.

Abstract

The invention relates to an additive for improving boar semen quality and an application thereof. The additive is prepared from the following components in parts by weight: 50 to 100 parts of procyanidine, 100 to 150 parts of curcumin, 100 to 200 parts of lauric acid, 10 to 50 parts of vitamin E, 20 to 50 parts of origanum oil, 10 to 50 parts of thymol, 50 to 100 parts of sodium butyrate, 50 to 200 parts of Chinese herbal medicine extract and 100 to 500 parts of carrier. According to the application, the additive is added into a boar basal feed for breeding boars or backup breeding boars of a swinery. Compared with the prior art, the sexual desire and semen quality of the boar can be improved (including the semen volume, the sperm density and the sperm motility rate of the breeding boar are improved and the sperm malformation rate is reduced), and particularly, the semen quality of the boar in a heat stress state can be remarkably improved.

Description

technical field [0001] The invention belongs to the field of feed, in particular to an additive for improving boar semen quality and its application. Background technique [0002] In recent years, the artificial insemination technology of pigs in my country has been further developed and widely used, which has greatly improved the utilization rate of high-quality breeding boars, reduced the amount of breeding boars, reduced the cost of breeding boars, and improved the efficiency of breeding , played a huge role in promoting the large-scale and intensified rapid development of my country's pig breeding industry. [0003] However, with the continuous improvement of pig breeding technology in my country, the requirements for the quality of pig semen are also getting higher and higher. Gradually improving the quality of boar semen has become one of the key factors for improving the quality of pig herds. Moreover, my country has a vast territory, and the summer high temperature s...
