How to distinguish between male and female chicks? How do you raise it? What is the suitable temperature? What are the aquaculture management techniques?

Chicks refer to newly hatched chickens, 0-50 days. The shell weight of chicks varies from breed to type, generally, the shell weight of broilers is about 40 grams, and that of laying hens is 36 to 38 grams. How to distinguish between male and female chicks? How do you raise it? What is the suitable temperature? What are the aquaculture management techniques? It was learned from Mr. Wei, a poultry farmer in Henan, that the temperature of the rearing room was 33 ℃ at 1-3 days old, 31 ℃ at 4-7 days old, 28 ℃ at 2 weeks, 26 ℃ at 3 weeks, 24 ℃ at 4 weeks, 22 ℃ at 5 weeks, and 20 ℃ at more than 6 weeks. Relative humidity 65%.

How to distinguish between male and female chicks?

1. Lift the chick's feet, lift the chick upside down, raise its head upward, and beat its wings, struggling violently, that is, the male chick. If the head naturally hangs down, the wings do not expand or then slowly close, most of them are female chicks.

two。 Hold the chicken in your hand, the chicken head up, the chicken and people facing in the same direction, to observe which side of the crown. If the crown is to the right, it is usually a male chick, and if the crown is to the left, it is usually a female chick.

3. The rooster walks with his head held high and his footwork is very special. If there are conditions, let the chicks walk in the sand, if the footprints are on the same line, it is a rooster. If the footprints cross each other, it is usually a hen.

How do you raise chicks? What are the aquaculture management techniques?

1. Preparation before brooding

(1) according to the number of brooding, the breeders build the brooding room according to the plan, and the brooding room is required to have windows to ensure adequate air circulation and daylighting, which can be built into a brick-wood structure or a greenhouse.

The number of the net bed is determined by the number of chickens raised, and the number of the net bed is calculated according to 30-50 chickens per square meter. the first floor of the net bed is 40 cm high from the ground, and the distance between the upper and lower layers of the net bed is 30 cm high. the dung board should be used at the top of the first and second floor net bed, and the skeleton of the net bed is made of wood or bamboo or special nursery cages, and the sides and bottoms are fixed with plastic nets. Reasonably equipped with feed buckets and drinking fountains. The three-dimensional net bed brooding greenhouse has the characteristics of saving space and raising a large amount of chicks, so it is suitable for specialized scale breeding.

The flat brooding is spread on the ground with about 1 inch long grass section as bedding material, with a thickness of about 2 cm. 3murl additional bedding grass for 5 days, keep the bedding grass dry until the chicks are out of temperature, and thoroughly remove the bedding grass when stocking is suitable for fledgling farmers.

(2) preparation of brooding supplies full-price chick formula feed, drinking fountain, feed bucket, dry and wet thermometer, sprayer, heat preservation equipment, commonly used drugs and so on.

(3) Comprehensive disinfection can be used for routine spray disinfection of the first chicken breeding site, and fumigation disinfection will be used later. the specific method is to close the doors and windows of the chicken house before disinfection, and then calculate the total dosage of drugs according to the volume of the chicken house (length × width × height). 10 cubic chicken sheds need formalin (formaldehyde) 250ml (about 4 taels) and potassium permanganate 15g (about 3 yuan), water 50g (12g). When operating, first pour the water into the corrosion-resistant pottery or enamel container, then add potassium permanganate and stir evenly, finally add formalin, and immediately leave the closed doors and windows of the chicken house.

two。 The basic requirements of brooding

(1) the body temperature of chicks just coming out of their shells is 2-3 degrees lower than that of adult chickens, so the heat preservation work is very important. the temperature of chicks should reach 32-34 degrees in the first week and 30-32 degrees in the second week. after that, the temperature will not drop more than 3 degrees per week, and 20 degrees will be fine after 4 weeks. To observe the temperature change at any time, put a thermometer in the four corners and the center of the nursery room to find out whether the indoor temperature is balanced. Another method is to observe whether the chicks are evenly and quietly scattered on the net bed or on the cushion. If the chicks are huddled together (pile), the temperature is low. If the chicks open their mouths and breathe, the temperature is high, and the temperature needs to be adjusted.

(2) appropriate humidity chicks are hatched from chicks with a relative humidity of 70%. If transferred to an environment with high temperature and dry bedding, a large amount of water is distributed in the chicks, resulting in poor feather growth, dry toes and respiratory diseases. Therefore, the relative humidity in the rearing room of chicks within 10 days of age is required to be kept at 65%, 75%, and about 60% after 10 days of age.

(3) timely drinking and eating chicks should drink water immediately when they enter the nursery. At the age of 1-3 days, they can drink 2/10000 potassium permanganate water (the water is light pink). For long-distance transport chicks, glucose and electrolytic multidimensional water should be added to the drinking water. Feeding takes place 3 hours after drinking water, and can be eaten when 60% of the chicks (2/3) can stand and walk at will. The number of feeding times is 1: 8 times a day at the age of 10 days (3 times at night), 5 times a day at the age of 20 days (twice at night), and 4 times a day at the age of 2130 days (once in the evening).

(4) feeding density requires 50 chickens per square meter at the age of 2 weeks, 30 chickens per square meter at 4 weeks, and 20 chickens per square meter at the age of 6 weeks. The number of chickens per small group should be 70-100. The number of drinking fountains (one for every 50 chicks) and feed buckets (one for every 50 chicks) should be adequate and placed properly.

(5) the light nursery uses 24-hour continuous light in the first week, and strong light can prevent all kinds of evils. The height of the 40-watt bulb is about 2 meters above the ground with a 40-watt bulb every 15 square meters. In the second week, the lamp is gradually reduced to 19 hours, and the 25-watt lamp is available from the third week.

(6) the air and sanitary conditions of the nursery should maintain good ventilation. If the ventilation is poor and the air in the house is dirty, it will produce a large number of harmful gases such as ammonia, carbon dioxide, hydrogen sulfide and so on, which will not only affect the health of chickens, but also cause respiratory diseases and even death. Hygiene is an important factor affecting the health and production performance of chickens. It is required to wash drinking water utensils every day, clean feeding utensils regularly, clean the house, and disinfect them. Regular ventilation, regular cleaning of chicken dung on the ground.

(7) after coming out of the shell, the chickens were injected according to the immune procedure, and the chicks were treated with drugs to prevent pullorum and coccidiosis within two weeks.

It is difficult to raise and manage chicks, so farmers need to be more patient and the management work is more precise in order to raise chicks well, improve the survival rate and create higher breeding efficiency.
