1 According to the identification of the genital process this method is best 2 ~ 12h after hatching, the latest do not exceed 24h, or else the reproductive process shrinks, the identification is more difficult. Method of operation: After the chicks are out of the shell, the hair drying can stand, hold it in the hands, eliminate the feces, sandwich the head between the middle finger and the ring finger, and press the thumb gently next to the anus to open the anus gently. In the bright light, if you see a small granular penis protrusion, it is a male chick. No projection is a female chick. Accuracy can reach 85% or more.
2 From the form of identification
2.1 According to the body type to identify larger body, heavy body, eyes are round, long and sharp, thicker feet are male chicks; smaller body, slightly lighter body, eyes oval, short and round, small feet It is female chicks. In addition, after 14-day-old chicks were compared, if the body is longer and heavier, the legs are higher, and the length of the second toe is not the same as the length of the fourth toe, it can be judged as a male chick; if the body is relatively round, the legs are lighter. Short, but the length of the second and fourth toes is the female chicks.
2.2 Walking identification Identify the male and female according to the toes printed after the chicken walks. Spread a layer of ash (such as grass ash, etc.) on the flat ground and let the chicken walk on the ash. If the chicken walks, the toes printed on the two toes cross to form a line, and when the animal walks around, the body swings around, which is generally regarded as a female chick. If you find that the toes left after walking are printed in two lines, you can think of them as males.
2.3 Natural Standing Discriminators identify males and females by observing their appearance. The front view is a square circle, which is generally considered to be a male; the front view is a small ellipse and is generally considered to be a female chick.
3 According to the contraction of the chick anal sphincter, the male is generally more developed than the female, and the anal sphincter contraction is also strong. Therefore, on the day when the chicks were newly hatched, the chicks were held in their hands and their anus contractions were observed. If the anus flashes for a while, it will stop for a while and then it will flash for a while. The number of contractions of the anus will be longer and slower. It will be the female chicken; if the contraction of the anus is quick and powerful, it will be the male chick.
4 According to feather identification
4.1 Identification of the normal female chicks from the update of the fluff earlier than the male chicks. After the first 4 days after hatching, new hairs have appeared on the chest and shoulders of the female chicks, but the male chicks do not have this phenomenon. At 15 days of age, female chick wings and tail feathers grow rapidly and their wing feathers appear rounded. At this time, the male wings are very short, sharp-edged, and have no tail feathers.
4.2 Identifying the shape of the feathers Pulling out the wings of the chicks, the feathers (feathers) are one short and long (that is, the length of the feathers). The females are all feathers of the same length and length. This method can identify male and female chicks with an accuracy rate of 98%. It is simple, rapid, accurate and effective in practical production.
4.3 Identification of so-called Sexuality Genetics through Sexual Genetics, ie, certain characteristics of offspring vary with sex. For example, when a reed and a non-reed brindle broiler are paired, their female hens are all non-reed brindles, and the males are all reed brindles; All are fast feathers, and the rooster is full of feathers; the silver-feathered hens are paired with the golden-feathered hens. Their female hens are golden and the roosters are silver. This is because the male and female chickens have obvious traits corresponding to each other, and the hens have dominant traits and the males have recessive traits.
5 different age chicks feeding
5.1 One-day-old chicken 1kg of boiling water by adding 100g of sugar made of sugar water for the chicken to drink, promote meconium discharge, while feeding the chicken fried corn scrap. The chicks were kept in small bamboo cages. The bamboo cages were raised and the chicks were kept out of contact with the ground. At night, the bamboo cage was surrounded with plastic film, the cage was left empty, and the plastic film was peeled off during the day. This kind of insulation measures is simple and practical.
5.2 Three-day-old chicks were treated with flumic citric acid powder 0.1g, dissolved in cold water and 1L cold water for chickens to drink, and used for 5 days to prevent diarrhea. Keep the temperature at 34Â°C and use cold boiled water for chickens. Feed 3 times a day, feed water first.
5.3 The 8-day-old chicks are mainly at room temperature and can be transferred to bamboo benches for feeding. At the same time, they are vaccinated with Newcastle disease II strains to prevent epidemic disease and control chicken gizzard disease. Before the 9th day of age, fry dried corn can be fed. Chickens can also be fed with insects and cockroaches, fed once a day, 80% of them are fed each time, and green feed is fed once every 3 days.
5.4 10-day-old chickens were treated with 100 ml homemade herbal medicine water for each 10 birds, and 150 ml of cold boiled water was added to dissolve chickens for drinking to prevent bird flu. Afterwards, once every 10 days, the chicken is served once with the herbal medicine water. From the 10th day of age, use clean water to mix the ingredients into semi-humid and semi-dry feeds.
5.5 After 30 days of age, press the chicken body weight with 0.4g/kg to drive the fleas. Stir in the chicken feed to kill the parasite. Once a month, use chicken litter again to keep chicken farm dry and clean.
