Problems solved by technology

In the process of artificial insemination, semen collection is an important process. Semen collection must ensure high-quality semen to avoid insemination failure. During the collection process, if the semen is not properly preserved, it may also cause damage to the semen, thereby affecting the fertilization rate.

Embodiment 1

[0033] like figure 1 Shown, a kind of laying hen semen collection cup, comprises the second fine chamber 2 that is flexibly connected with the first fine chamber 1, and the bottom of the first fine chamber 1 is connected with the top of the second fine chamber 2, and the first fine chamber 1 is Double-layer structure, the first fine chamber 1 is provided with an inner chamber 4, the inner chamber 4 is separated from the outer wall of the first fine chamber, the inner chamber 4 communicates with the second fine chamber, the bottom of the inner chamber 4 is inclined to the middle, and the bottom of the inner chamber 4 The middle part is provided with a protrusion, and the diameter of the bottom surface of the protrusion is equal to the diameter of the communication channel between the inner chamber 4 and the second fine chamber. The inner chamber 4 is made of porous water-absorbing material, and there is a diluent between the inner chamber 4 and the first fine chamber 1 . The s...

Embodiment 2

[0037] The crotonate grafted chitosan was prepared by the following steps,

[0038] Step 1: Weigh a portion of chitosan, take an appropriate amount of water as a solvent, adjust the pH of the solution to 4.7, add an appropriate amount of isopropanol to prepare a suspension with a starch mass fraction of 37%, and stir for 30 minutes;

[0039] Step 2: add NaOH to the solution according to the chitosan:NaOH mass ratio of 1:0.05, heat up to 30°C, stir at a constant temperature for 30 minutes, and slowly add allyl dropwise to the solution according to the NaOH:allyl chloride molar ratio of 1:1.2 base chloride, warming up to 50°C, stirring at constant temperature for 24h;

[0040]Step 3: filter, take the solid and redisperse it in a distilled water-ethanol solution with a volume ratio of 18:82, adjust the pH to 7 with acetic acid, wash with an appropriate amount of distilled water after suction filtration, and dry to obtain allyl etherified chitosan;

[0041] Step 4: Take a portion...

Embodiment 3

[0044] Nano-hydroxy calcium phosphate / polycaprolactone / polylactic acid is prepared by the following method: through the reaction formula Ca(NO 3 )·4H 2 O+(NH 4 ) 2 HPO 4 → Ca 10 (PO 4 ) 6 (OH) 2 To prepare nano-calcium hydroxyphosphate, configure nano-calcium hydroxyphosphate into a slurry with a mass fraction of 5%, add the slurry to a three-necked bottle with a water separator, a stirring device and a condensation device, and add 150mL solvent DMAC and an appropriate amount of polyethylene glycol at the same time. For diol, the temperature is gradually increased to 100°C, dehydrated at 100-120°C, then polycaprolactone and polylactic acid are added in proportion, stirred and compounded for 4 hours at 120-130°C, taken out, and washed with hot deionized water for 4 hours times, washed with ethanol twice, and dried at 50-60°C for 48 hours to obtain a composite material.

Abstract

The invention discloses a sperm collection cup for breeding egg chicken and belongs to the field of poultry breeding. The sperm collection cup comprises a second sperm camber movably connected with a first sperm chamber, wherein the bottom of the first sperm chamber is connected with the top end of the second sperm chamber, the first sperm chamber is of a double-layer structure, and an inner chamber is arranged in the first sperm chamber and spaced from the outer wall of the first sperm chamber; the inner chamber is communicated with the second sperm chamber, the bottom of the inner chamber tilts towards the middle, a protrusion is arranged in the middle of the bottom surface of the inner chamber, and the diameter of the bottom surface of the protrusion is equal to the diameter of a channel allowing the inner chamber to be communicated with the second sperm chamber. The sperm collection cup has the advantage that during collection, impurities which are collected accidentally can be filtered out, sperm can be diluted during collection, a proper sperm storage condition can be provided so as to guarantee the vigor of sperm, and then artificial insemination effect can be guaranteed.

Description

technical field [0001] The invention relates to an artificial insemination appliance, in particular to a sperm collection cup for layer breeder hens. Background technique [0002] In natural mating, each male can only mate with 6 to 16 females; however, with artificial insemination, each male can complete the mating task of 110 to 180 females per week. Therefore, in the process of poultry breeding, artificial Insemination is an important part of breeding, which has the advantages of simple operation, high fertilization rate, disease prevention, reduced cost of breeding male poultry, and high income. In the process of artificial insemination, semen collection is an important process. Semen collection must ensure high-quality semen to avoid insemination failure. During the collection process, if the semen is not properly preserved, it may also cause damage to the semen, thereby affecting the fertilization rate. . Contents of the invention [0003] The purpose of the presen...
