Teach you how to distinguish between male and female pigeons

Pigeon meat is rich in nutrition, delicate meat, good taste, high nutritional value than other poultry, has always been the top grade of meat, known as "one pigeon is better than nine chickens". It is not only a valuable delicacy, but also an advanced tonic, which has the effects of tonifying qi and tonifying blood, and has a certain auxiliary effect on hair loss, eczema and premature senility. it is especially suitable for pregnant women, children, the elderly, surgical patients and the weak. The market potential of squab consumption is huge. There is little difference in the appearance of male and female meat pigeons. Male and female identification is an important link in the introduction and breeding of meat pigeons, and meat pigeons are typical breeding methods of "one wife a day". If the sex ratio is not appropriate, pigeons are not only reluctant to give up peace, but also affect the laying rate. Several identification methods are introduced for reference.

I. embryo identification of pigeon eggs

The fertilized eggs hatched for 4 days and 5 days. Observed under the light, the blood filaments on both sides of the basic axis of the embryo were symmetrical, and the male embryos were in the shape of spiders. The blood filaments on both sides of the embryo are asymmetrical, with long and many filaments on one side and short and few filaments on the other.

Second, the male and female discrimination method of squab

The main results are as follows: 1. Comparative identification of appearance: in the same litter, male pigeons are fast growing, large in size, short and thick neck, large and flat nose tumor, stout feet, long and wide beak and forked tip of tail fat gland. After 10 days of age, put your hand in front of the squab, and the responsive and finger-pecking ones are males; when they can walk, they are lively and active, who often leave the pigeon nest, with a thick head, a thick beak and a slightly short beak, and when feeding parent pigeons, the first eaters are male pigeons, on the contrary, females.

2. Anal identification: before 4-5 days of age, turn over the anus to observe its shape to distinguish male and female. Pull its anus open slightly, from the side, if the lower edge of the anus is shorter, the upper edge covers the lower edge, the upper edge is slightly prominent for the male pigeon, the upper edge of the anus is shorter, the lower edge is longer, and from behind, the female pigeon tends to bend slightly downward at both ends.

III. Male and female identification of child pigeons

A child pigeon is called a child pigeon whose nests have been divided at the age of 28 and 30 days. This is for male and female identification. The squab that is not used for breeding has been put on the market for meat on the 22nd to 28th. The head of the male pigeon is thick, the top is arched, the mouth is large and slightly short, the beak is thick and short, the nose tumor is large and prominent, the neck bone is thick and hard, and the foot bone is thick. The female pigeon has a compact body structure, a small round head, a flat upper part, a small nose tumor, a long and narrow mouth, a thin and long beak, a thin and soft neck and a short and thin foot bone. The keel of the male pigeon is long and curved. When the male pigeon is caught by hand, the male pigeon is more resistant and makes a "goo" sound. The keel of the female pigeon is short, straight and docile, and sometimes makes a "no" sound. Grasping the direction of the light opposite to the neck, we can see that the male's eyes are bright and bright, and the nictitating membrane flashes rapidly; the female pigeon's eyes appear mild, and the nictitating membrane flashes slowly. For pigeons over 3 ~ 4 months old, when the anus of the male pigeon is closed, it protrudes outward and is hexagonal when it is opened; when the anus of the female pigeon is closed, it is recessed inward and flower-shaped when it is opened.

IV. Male and female identification of adult pigeons

The identification methods of child pigeons are applicable to adult pigeons, and the performance of adult pigeons is more prominent. In addition, you can also refer to:

1. Male pigeons often chase female pigeons, revolving around female pigeons, neck feathers and back feathers protruding, tail feathers open, and mop the floor from time to time, frequently moving their heads up and down, making a cooing sound. The female pigeon is more gentle, walking slowly or squatting with her head half-bowed. In estrus, he often snuggles up to the male pigeon with a low sound.

2. The tail feathers of male pigeons are dirty, while the back feathers of female pigeons are dirty.

3. when the matching pigeon kisses, the male pigeon opens its mouth, and the female pigeon puts its beak into the mouth of the male pigeon. After the kiss, the female pigeon naturally squats down and accepts the mating of the male pigeon.

4. in general, most male pigeons hatch their eggs from 10: 00 a.m. to 4: 00 p.m., while females usually hatch their eggs from 5: 00 p.m. to 9: 00 a.m. the next day.

5. During the laying period, the pelvis of the male pigeon is narrow, the distance between the left and right pubis is about one finger wide, and that of the female pigeon is about two fingers wide.
