Embodiment 1

[0019] In order to test the total effective sperm count described in the method of the present invention to judge the reliability of boar semen quality. The total effective sperm counts of different values ​​were selected, and 20 sows with the same fertility and normal fertility were artificially inseminated, and the conception rate and litter size were detected. The results are shown in Table 1:

[0020] Table 1 The data table of the reliability experiment results of total effective sperm count in judging boar semen quality

[0021]

[0022]

[0023] Note: The numbers are represented by ± standard deviation, "*" means significant difference by T test (P<0.05)

[0024] From the data in Table 1, it can be seen that the greater the total effective sperm count, the greater the data on the breeding conception rate and litter size, which means the higher the quality of boar semen. Therefore, it can be shown that the method of the present invention is reliable, and the total...

Embodiment 2

[0026] The test situation of the influence of organic trace elements on the quality of boar semen carried out in the boar station of the original breeding farm of Shuitai Pig Breeding Company from February to June 2014:

[0027] Table 2. The test results of organic trace elements in the original seed field of Shuitai

[0028]

[0029] From the data before and after the test, after the test, the volume decreased by 7.54ml, the vigor decreased by 0.01, but the density increased by 0.02, and the deformity rate improved by 0.13%. The four indicators were within the normal range before and after the test. It is difficult to evaluate the influence of organic trace elements on the quality of boar semen according to these four indicators, but from the perspective of the total effective sperm count, the effective sperm count after the test was reduced by 11.07, which can explain the effect of organic trace elements on the improvement of boar semen The quality doesn't help.

Embodiment 3

[0031] Experiments on the effect of vitamin compound package on the quality of boar semen carried out in the boar station of Shiwang Erchang of Yangchun Company from April to August 2014

[0032] Table 3. Test results of vitamin compound package in Shiwang Erchang

[0033]

[0034] From the data before and after the test, the boar semen volume increased by 45.03ml after the test, the motility increased by 0.01, the deformity rate improved by 2.51%, but the density decreased by 0.25, and the four indicators before and after the test were all within the normal range. It is somewhat difficult to evaluate the effect of vitamin compound package on boar semen quality based on these four indicators, but from the perspective of effective sperm count, the total effective sperm count increased by 26.56 after the test, indicating that vitamin compound package can improve the semen quality of boars There is some help.

Abstract

The present invention relates to the technical field of culture and particularly discloses a simple method for comprehensively evaluating the quality of boar semen. The method comprises the following steps of: firstly, detecting four indexes, namely sperm density, semen quantity, sperm viability and malformation rate; secondly, calculating the total number of active sperms according to a calculation formula; and thirdly, evaluating the quality of the boar semen according to the total number of the active sperms. According to the method, the quality of the boar semen can be objectively and accurately evaluated.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a simple method for comprehensively judging the quality of boar semen. Background technique [0002] After the boar semen is collected, the semen quality must be evaluated first, and then the semen can be further processed, so as to ensure sufficient quantity and vitality of sperm for artificial insemination, and the health status and reproduction of boars can be monitored through the evaluation of semen quality Potential, so as to optimize individual genetic potential and maximize reproductive capacity. [0003] The main indicators for evaluating the quality of boar semen are color, smell, ejaculate volume, vigor density and deformity rate. Normal semen is milky white or off-white with a slight fishy smell. If it is yellow, it is usually mixed with urine; if it is light red, it is usually mixed with blood; if it is yellowish brown, it may be inflammation mixed with pus; abnor...
