There are two main ways of mating in geese: natural breeding and artificial insemination. How geese mate are described in detail below.
1. Natural breeding
1.Mating location: Geese have a habit of mating on the water, so natural mating usually takes place on the surface of the water. Breeding goose farms need to provide clean swimming grounds to meet the mating needs of geese.
2.Breeding time: Usually before 9 o'clock in the morning is the time when the male goose has the most sexual desire, so the breeder should carry out the breeding operation during this time period.
3.Preparation for breeding: Before breeding, it is necessary to put the male goose into the breeding site and extend the breeding interval appropriately. Generally speaking, each female goose is mated every 5 days, which can improve the quality of mating, reduce the number of male geese raised, and reduce production costs.
4.Mating posture: The keeper squats on the left side of the female goose, grabs the legs of the female goose with both hands and keeps it to prevent swaying from side to side during mating. The male goose jumps on the back of the female goose and pecks the feathers on the top of the female goose's head with his beak, pressing the tail forward and downward, while the female goose upturns. The ** of the male goose is inserted into the ** of the female goose and **.
5.Improve the fertilization rate: In order to improve the fertilization rate, you can gently press the tail of the male goose after the male goose leaves, which can deepen the ** part and improve the fertilization rate. At the same time, the keeper should also quickly put the cloaca of the female goose up and gently press it around it to prevent ** from flowing out of the cloaca.
2. Artificial insemination
1.Preparation for sperm collection: In order to improve the utilization rate of improved male geese, artificial insemination technology can be used. First of all, it is necessary to separate the male goose and the female goose from the sperm collection, and cut off the feathers around the cloaca of the female goose to prevent ** pollution.
2.Sperm collection method: A commonly used sperm collection method is dorsal and abdominal massage sperm collection. The assistant holds the feet of the male goose, sits in front of the right side of the sperm collector, puts the male goose on his lap, tail outward, and his head under his left arm. The sperm collector massages the back and waist of the male goose with his left hand, while holding the cloaca with his right hand until the muscles around the cloaca are congested and swollen and feel protruding. Then, change the technique, use the thumb and index finger of the left and right hands to cling to the left and right sides of the cloaca, and gently squeeze the upper part of the cloaca in a rhythmic manner to make the ** erection stretch out. Finally, import the male goose's goose into the container where it was collected.
3.Dilution**: After the collected ** is normal on microscopic examination, it can be diluted with the same or multiple amounts of **diluent according to sperm concentration and motility. Commonly used ** dilutions include 09% sodium chloride saline (normal saline), etc.
4.Insemination process: The mother goose is fixed on the fertilization table (stool) with the cloaca facing outwards upwards. Wipe the area around ** with a saline cotton ball and gently press down on the cloaca to open it. Then, the diluted ** sperm is slowly inserted to a depth of about 5-6 cm, and then the left hand is relaxed, and the right hand is inserted into the ** in the sperm vessel. The insemination time is usually around 4 am or 4 pm, and each female goose loses 1 time every 56 days, each time 01 ml. At the first insemination, the amount of sperm transfusion is doubled, which can increase the fertilization rate to more than 90%.
To sum up, the mating process of geese includes two ways: natural mating and artificial insemination. Either way, it needs to be done in the right environment to ensure a smooth mating. Artificial insemination can improve the utilization rate of improved breeds of male geese and reduce the number of male geese raised, but it also requires appropriate techniques and methods to operate.
