Identification method of male and female partridges

I think many people have heard of partridges, but perhaps many people have not eaten them. Everyone who has eaten them should know that partridges look small. Although they are long and small, they are well-equipped with five internal organs and have high nutritional value.

Identification method of male and female partridges

1. Hand-held method: lift the legs of the chicks upside down by hand, such as the body is heavy, the head is stretched forward, the wings are spread and do not swoop at random, they are generally male; if the head is bent to the chest, the body works hard upward, and the wings swoop randomly, it is generally a female.

2. The method of turning the anus: lift the wings of the partridge and gently open the anus. If there is a cone protruding in the anus, the male is located in the center of the wrinkled wall of the anal cavity, and vice versa, it is the female.

3. The method of looking at the legs: it is difficult to distinguish between male and female from the appearance of young partridges, but there is a slight difference after adulthood, and the sex difference begins to show gradually after 3 months of age. The main difference is that there is a flat triangular protuberance on the medial side of the shank of the male partridge, but at this time, the distance between the two sides is not symmetrical. Generally, at the age of 4 months, the shank surface is protruding 0.15-0.2cm, and most of the female partridges have no flat triangular protuberance. A few of them are only one foot and are not as obvious as male partridges.

4. the method of looking at the appearance: although the male and female of the adult partridge cannot be distinguished from the feathers, it can be found that the head of the male partridge is large and square, the neck is shorter and the body is slightly longer, while the female is slightly smaller, the neck is slightly slender and the body is slightly round.

The breeding value of Partridge

Partridge is a kind of rare meat bird with high breeding value. It is not only suitable for intensive large-scale breeding in farms, but also suitable for thousands of families in urban and rural areas. it is a good project for the development of courtyard economy. Partridge has low requirements for breeding environment, because it has strong adaptability and is suitable for raising in the north and south provinces of our country, and the equipment is simple, the investment cost is low, and it is easy to raise and manage.

Growth characteristics and reproduction of partridges

Partridges weigh 14 grams after coming out of their shells, and then grow rapidly. Meat partridges weigh 500g in 3 months, and the average weight at the age of 90 days is 500g, which is 40 times of the birth weight. The ratio of feed to meat is 35 ∶ 1. The growth rate slowed down after 90 days of age. Raising commercial partridges, each person can manage 2000 partridges and can produce 4 batches every year.

After 28 days of age, partridges were transferred to the breeding partridge stage, which began to produce at the age of 7 ~ 8 months, and the male partridges were sexually mature for 8 months. The ratio of male to female in captivity was 1 ∶ 3 to 1 ∶ 4. Under better feeding conditions, an average of 100,120 eggs are produced per year. The service life of breeding partridges is 3 years. The fertilization rate is generally as high as 92% to 96%. The hatching rate is 84% and 91%. The incubation period of partridge eggs is 24 days. The incubation temperature is 37.8-37.2 ℃ in winter and 377.5 ℃ in summer. It can be hatched manually or with a modified electric incubator.

Key technical points of partridge breeding and management

1. Partridge breeding mode: choose the place where the leeward to the sun, good drainage, warm and dry, quiet environment, water, electricity and traffic conditions are better. If the breeding scale is larger (more than 5000), partridges should be chosen far away from residential areas (more than 1000 meters). Partridges before 4 weeks of age should be raised away from the ground, preferably off the ground and netted at the age of 4 weeks. After 12 weeks of age, the animals were reared in cages according to a small group of 1 ∶ 3 to 1 ∶ 4. A sexually mature partridge can keep a pair of partridges in cage. A playground should be set up outside the house. The general caged areas of partridges are as follows: 70 partridges per square meter at the age of 1 week, 50 birds per square meter at the age of 4 weeks, and 10 birds per square meter at the age of 4 weeks. Chinese partridges also need to be equipped with a playground.

2. Feed and feeding: partridges have a wide range of recipes, and the feed should be mainly mixed feed for chickens. During the growing period, the daily feed consumption is 20 grams; the egg-laying partridges consume 25 grams per day. Partridges are sensitive to moldy feed. When storing a large amount of feed or processing pellet feed, high efficiency feed anti-mildew agent should be added.

3. Key points of partridge breeding and management

① is a nestling before the age of 4 weeks and should be kept in an incubator. If the temperature is kept at 35-37 ℃, the chicks should drop to 26-28 ℃. The chick begins to feed water 12 hours after it comes out of its shell. 1000 of 4-day-old chicks need only 3 liters of water. Young partridges can be eaten after drinking water. Full price granules that can be crushed can be used. In order to ensure its nutritional needs, an appropriate amount of boiled eggs, cod liver oil and vitamin B solution can be added. If the upper beak is bent, the tip of the beak can be cut off at the age of 3 days to make the upper and lower beaks match.

The stage from 90-day-old to pre-laying stage of ② is called Zhongtridge. Semi-open-air or indoor flying breeding or double-layer cage can be used. Feed with chicken feed or full-price granular chicken feed. Feed, 30 grams each, 35 grams per day. Let them drink freely to ensure their water needs. Train partridges to follow orders before laying eggs.

② meat partridges, that is, commercial partridges should be raised in groups to provide comprehensive nutrition and reasonable formula of breeding fertilizer. It can be fed by dry feeding, wet feeding or dry-wet feeding. The suitable temperature for meat partridge is 18-25 ℃. The feeding density is 1216 cages per square meter, and the cage height is not more than 30cm. The light in the cage should be controlled, the lighting time is 20 hours a day, and the feeding method is proper, which can reach 500 kilograms and 600 grams in 2.5 months.

It is now that people's living standards are constantly rising, and people's diet requirements are getting higher and higher, and they like to try some things that are usually unavailable or more difficult to eat, so the market demand for partridges is also gradually increasing.
