The source of the intima and the source of the selected indicatrix should mainly adopt the artificially cultivated seedlings, and select the fine varieties such as the deep yellow and large brown beetle. The body is required to be healthy, disease-free, injury-free, body-shaped hypertrophy, bright color, and dark yellow body color. General females require a body length of 30 cm or more and a body weight of about 100 grams.
Discrimination of female and male ferrets In the breeding season, females are swollen and transparent in the abdomen and sexually mature individuals. The abdomen is pale orange and has a purplish red horizontal stripe. The male's head is larger and the uplift is obvious; many leopard skin pigment spots are visible on the back of the body; the abdomen is not significantly swollen, and there are bloody markings on the ventral surface.
Intimate cultivation of intimacy should be meticulously cultivated before oxytocin production, so that the gonads reach maturity. The stocking density for cultivating relatives was 2 to 3/m 2 and 7 to 8/m 2 for females. The feed is preferably fed with high-quality live bait or fly maggots. The water depth is maintained at 20 to 30 cm, and new water is often added to maintain good water quality. Put some aquatic plants in the pond, such as water lettuce, water hyacinth, and so on. Shade and protection function.
The indulgent oxytocin-promoting agents used luteinizing hormone-releasing hormone analogues LRH-A, or human chorionic gonadotropin (HCG), to use LRH-A as the main ingredient, and the dosage was increased or decreased according to the individual size of the jaundice.
(1) Oxygen-injection solution injection method: The amount of anaesthetic solution injected by each endophilus is 1 ml. During operation, one person will select the good relative to wrap the carcass with a dry towel so that the abdomen faces upward and the other performs In the abdomen, the direction of the needle is approximately 45 acute angles with the anterior aspect of the intimacy, and the depth of penetration of the needle does not exceed 0.5 cm. Because of the different effects of male-female procreation, female cockroaches produce a slower effect than male cockroaches. Therefore, in actual operation, the injection time of the male must be delayed by about 24 hours compared with the female. Inject a good male and female pro-scorpion into the cage for raising, water depth to maintain 30 to 40 centimeters, pay attention to the frequent injection of new water, temporary raise 40 to 50 hours, you can observe the maternal maturity and estrus.
(2) Artificial insemination: Take out the female ovulation which starts to ovulate, hold the front towel with a hand towel and squeeze the abdomen with the other hand from front to back. Blocking phenomenon, this time can be cut with a small scissors in the cloacal inward 0.5 to 1 cm, and then the egg extrusion, continuous 3 to 5 times, squeezed so far. The ovulation container can be glass or porcelain. After the egg is squeezed into the container, the male cricket is killed immediately. The testis is removed and a small part is placed under a microscope with a magnification of 400 times. If the sperm activity is normal, the scissors can be used. The testis was smashed and placed in an extruded egg, fully stirred (male and female ratio at the time of artificial insemination, depending on the amount of eggs, generally 3 to 5:1), and then added Renji's solution to 200 ml for 5 minutes. Add clean water to wash testicle fragments and bloodstains and put them into an incubator to incubate in still water.
(3) Artificial hatching: When hatching artificially, it can be hatched in an incubation tank. Incubation tanks with a volume of 0.25 m3 can contain 200,000 to 250,000 fertilized eggs. In the water temperature of 25 ~ 29 °C conditions, fertilized eggs can hatch after about 6 days. The newly hatched Aberdeen, 10 to 20 mm in length, lies on the side under the water. 5 to 7 days after filming, when the body grows to 25 to 30 mm, the yolk sac almost disappears, the pigment is covered in the head, and the pectoral fins and pelvic fins are degraded and disappeared. The larvae start normal swimming and feeding and can be transferred to the larval pool. Artificial cultivation.
Rice soup is also called
rice oil. It is a layer of porridge oil that is condensed on the pot
when it is served with fine rice porridge or dried rice. Rice soup is sweet and sweet, it can nourish yin and have a good nourishing effect.
The
best rice soup should be made with the unsalted rice and the aleurone
layer. The nutrition and health care function will be the strongest.
With the current refined rice, the effect will not be obvious,
especially after the panning. It`s even less nutritious.
