The economic value of guinea fowl
Guinea fowls are tender, nutritious and delicious. Compared with ordinary broilers, the protein and amino acid content is high, but the fat and cholesterol content is very low. It is a kind of special poultry with game.
The slaughter rate is high and there are more edible parts. The guinea fowl has delicate skeletons, small head and neck, well-developed chest muscles, and an elliptical body. The guinea fowl with a live weight of 1700 grams had a body weight of 1,540 grams, which accounted for 90% of the live weight, and a half net weight of 1,400 grams, which accounted for 80% of the live weight. It was thus seen that the slaughter rate and the meat yield were higher.
Guinea pigs have high production performance. The breeding hens started production at the age of 28 weeks. About one-hundred hens can produce about 160 eggs and provide about 110 broilers. Each broiler breeder consumes about 40 to 45 kilograms of eggs. The best slaughtering time for commercial chickens is 12 to 13 weeks old, with a live weight of 1100 to 1300 grams and a meat to meat ratio of 1:2.7 to 2.9.
The guinea fowl has good adaptability, strong disease resistance, simple requirements for equipment and premises, resistance to rough feeding, and easy feeding. Therefore, the guinea fowl rearing industry has less investment, fast turnover, and high efficiency. In addition, the individual size of the guinea fowl is modest, neither is it as large as a turkey needs to be sold for sale, nor is it as small as quails. It is suitable for ordinary family meal, but also high-grade meat and poultry on the banquet.
The habit of guinea fowl
Adaptive
Adult guinea fowl are dry, wet, resistant to high temperatures, cold and resistant to disease. It can still live at -20～40°C. However, if the temperature of the hatched chicks is slightly lower, they are susceptible to cold, diarrhea or death.
Wild nature, timid and frightened
The guinea fowl still retains the characteristics of a wild bird and enjoys its habitat. At night, it can also see its activities. In particular, chicks have a lot of activity, and they often go around and cause death. Feeding should pay enough attention to this habit. The temperament, timidity, alertness of the guinea fowls, and the abnormality or movement of the environment can all cause the group to panic. The hens make a harsh call and the chickens will have a chain reaction. If the red drinker is replaced with a yellow drinker, the chickens will not dare to approach the drinker for a long time.
Grouping and homing
Guinea fowls usually live in groups of 30 to 50, and are never separated. After artificial domestication, they still enjoy group activities. In case of fright, they also flee and hide in groups. Therefore, guinea fowls are suitable for rearing in large groups. In addition, guinea fowls are relatively strong. The homing nature, when returning to the nest in the evening, often returns to their homes, and occasional loss can also return home.
Good flying, love climbing, good activities
The guinea fowls are well-developed on both wings and they have a certain ability to leap at the age of one day. During the day, I can almost walk around. Love to climb high places at rest or at night.
Hi sand bath, love tweets
The guinea fowl are scattered on the surface of the land, and often one or more earth pits are drilled on the ground to provide sand bath conditions for themselves. When sand bathing, spread the sand evenly between the feathers and the skin. Guinea pigs have a rhythmic and coherent squeaky tinnitus, which is a major feature. The squealing disturbs people's rest very much, but it also has several effects. First, there is a strong alarm at night when this ringing sound is strong. The second is that if this whisper is reduced, or if the intensity of the sound is weakened, it may be a sign of the disease.
Selective sex
The guinea fowl is selective to the opposite sex, which is one of the reasons for the low fertilization rate when the chickens naturally mate. Of course, vulnerability to fright is also a major reason for the low fertility rate of large groups of guinea fowls. However, artificial insemination can fundamentally solve the problem of low fertility.
Wide breadth of food, resistant to roughage
In general, cereals, bran, cakes, and fish meal can all be used together. In addition, we especially like grass, vegetables, leaves, fruits and other green plants.
Artificial insemination
Pre-insemination preparation
In order to meet the needs of artificial insemination, when the breeder is raised to 25 weeks of age, it should be transferred to the breeder cage of the laying house. Transferring the group should be carried out under low light during the night. When catching chicken, it is better to catch chicken feet and not catch wings to prevent the wings from breaking. Since breeder chickens have been using the ground for raising in the rearing period, they will not be able to adapt to the cage immediately, and will often crash into cages, especially when people or other abnormal movements are seen. In order to relieve the stress response, it is best to allow them to feed freely and feed some green feed that Zhuxi loves to eat.
In order to disperse cages to stimulate chickens. Vitamins can also be added to feed to relieve stress. The caged chickens should be healthy, strong, and free from disability. The ratio of males and females can be slightly larger than that of natural mating (1:6).
After the male and female chickens are caged for a few days, when they are basically adapted to the caged living environment, the artificial insemination training for male and female hens should be started immediately. The content is the breeding training for the male rooster and the conversion of the female hens. Anal training. At the beginning, specialized personnel should enter the shed more frequently and try to touch and stroke the chicken as much as possible so that the chicken can get used to getting close. At this time, chicken training can be conducted. After they become familiar with these movements, they can begin to collect sperm. And turn anal training. In the course of training, we must be responsible for the person responsible, the action is light and steady, rapid and accurate, and not rash or rude. Training should avoid laying time in the morning.
Artificial insemination method
The main equipment consists of cleaning, disinfection, and drying equipment for the collection of fine cups, test tubes, microscopes, slides, coverslips, infusion drops, diluents, alcohol, and instruments.
The semen is massaged and it needs 2 to 3 people to complete it. One person can sit on a bench and put the rooster head backwards, the chest pressing on the legs, and the abdomen and cloacal cavity suspended outside the legs; the chicken chest can also be placed directly. On the bench, two legs hang down under the bench; sometimes the chicken body can be clamped between the left elbow and the left waist. But in general, the force should be moderate. Another person rhythmically massaged several times with his right hand along the back and back of the cock, then the left thumb and the other four fingers quickly massaged and shaken on the two sides of the cloaca (around the anus), causing it to irritate and trigger the erection of the copulator. When the sperm is exhausted, the right hand quickly collects the semen with a sperm collecting device, and at the same time uses his left hand to squeeze on the two sides of the cloaca and promotes the ejaculation.
In order to ensure the quality of semen, a drop of seminal liquid can be sucked on the slide glass with a pipette, plus 1 drop of normal saline, and covered with a cover glass to observe and identify the vitality, density, and quality of the sperm under a low magnification microscope. The semen meeting the requirements was pipetted into a test tube filled with a 0.9% physiological saline diluent, diluted 1:1, and the hens were inseminated in time. The insemination was completed by two people. One person grasped the hen's legs and lifted the abdomen inwards with his left hand. He pressed the tail of the hen with his right hand and opened the anus with separate thumb and forefinger to expose the fallopian tube. The mouth is on the upper left side of the cloaca, and the right side is the rectum opening). When the fallopian tube is completely opened, another person inserts the vas deferens obliquely into the fallopian tube by 2 to 3 centimeters, and slowly enters the semen.
Precautions
Rooster collects sperm weekly
Two or five days of sperm extraction, the hens inseminated once every 5 days. The insemination volume of each hen was 0.013 to 0.015 ml of pure semen. Hens should be inseminated a few hours after laying or inseminated hours before the next day.
