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

[0036] Such as 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 . Th...

Embodiment 2

[0040] The crotonate grafted chitosan was prepared by the following steps,

[0041] Step 1: Take 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;

[0042]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;

[0043] 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;

[0044] Step 4: Take a portion ...

Embodiment 3

[0047] 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 porous water absorbing material and relates to the field of materials. The porous water absorbing material is prepared from the following components in parts by mass: 20 parts of azodicarbonamide, 11 parts of polycarbonate, 4 parts of crotonate grafted chitosan, 37 parts of nano hydroxyl calcium phosphate / polycaprolactone / polylactic acid, 30 parts of a polylactic acid-polybutylene succinate-polylactic acid triblock copolymer and 20 parts of magnetic Fe3O4 / Ag nanoparticles. The porous water absorbing material has a lot of pore structures, has a relatively great absorbing ability, can absorb a lot of immersion liquid, and has a good water retention property, and natural volatilization of water can be reduced greatly.

Description

[0001] This application is a divisional application of the invention titled "A Cup for Sperm Extraction of Layer Breeders" [0002] The filing date of the original application is: 2016-09-20 [0003] The application number of the original application is: 2016108339516. technical field [0004] The invention relates to the field of materials, in particular to a porous water-absorbing material. Background technique [0005] 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 t...
