Improve the bred rate of chicks

1. Make preparations before brooding. Before hatching, the young house should be completely and thoroughly disinfected. Wash the ground and walls first, then use 0.3% of strong disinfection solution or 0.5% poison solution, 3% caustic hot solution to spray disinfection, completely kill all kinds of viruses and bacteria. The well-closed brooding house is fumigated with 20 g of potassium permanganate and 40 ml of formalin for 1 hour per cubic metre of space. During the fumigation, feed troughs, drinking fountains and other utensils can be placed in the brooding house. Simultaneous disinfection. After disinfection, open the doors and windows to allow air convection for 1 day. After the brooding house has been sterilized, non-sterile utensils are prohibited from moving into the house to avoid recontamination.

2, choose healthy chicks to raise. Chicks are subject to individual selection. The criteria for selection are: clean anus, no yellowish white dilute fecal adhesions, good umbilical cord absorption, no blood marks, good abdominal contraction, not large bellied chickens, blemishes, eyes, legs, and claws are not abnormal. Those healthy chickens that meet the four criteria are not allowed to be used if one of the criteria is not met, because the weak chicks have a low survival rate and a slow growth rate and are not suitable for keeping.

3. Ensure proper brooding temperature and humidity. The chicks need higher temperatures: The temperature of the brood is 33°C to 35°C in the first week, and then falls by 2°C per week. After about 6 weeks, the chicks can adapt to the natural environment. If the temperature is appropriate, it cannot be measured by a thermometer. It is important to look at the performance of the chicks to see how the chicken heats. The temperature is too high, the chicks spread out, gasping for breath, loss of appetite, and increased drinking water; the temperature is too low, the chicks are disturbed by sleep, and buzzing sounds, often crowded together, or even plucked together. The long time causes a large number of chicks to die phenomenon. When the temperature is appropriate, the chicks are lively, eating normally, and in good spirits. Practice has proved that maintaining a proper brooding temperature has significant effects on controlling the occurrence of white plague and coccidiosis in chicks, promoting the absorption and utilization of yolk sac, and improving the survival rate of chick brooding.

The humidity of the brooding house should be indicated by a dry hygrometer. If it is too high or too low, it is not suitable for the growth and development of the chicks. The ideal humidity is maintained at 60% to 70% in the first week and 55% to 60% in the second week. Humidity is too low, house dust and feather dust are flying high, chicks are susceptible to respiratory diseases, and feathers are stunted. When humidity is high, harmful gases increase, which is conducive to the survival of pathogenic microorganisms and the development of parasite eggs. Chicks are prone to various diseases. .

4, provide adequate drinking water. Traditional chicken farming in rural areas often does not dare to give chicks drinking water. It is said that it is chickens that cause chicken diarrhea. Actually, chicks should be given drinking water when they go out into the brooding house and add penicillin 1,000 units per pigeon in drinking water, and then drink 3% brown sugar water after 2 hours. Then use warm water to add appropriate amount of water in warm water. Concentrated multivitamin B solution. In addition, to prevent shortage of water and intermittent water supply, drinking water should be continuously available and free to drink at any time. Water shortages and intermittent drinking water will cause chicks to become thirsty and cause water grabbing, causing chickens to drink and cause death. Another consequence of water robbing is the phenomenon of many chicks getting wet and getting cold and crushed. If they are not discovered in time, it will cause undue losses.

5. Pay attention to the feeding of chicks. When one-third of chicks have a search for food, they can eat it. It is usually eaten within 24 hours after being shelled. Feeding chicks to do: feeding full-priced compound feed, regular ration, the number of feeding is generally fed 7 times a day for the first two weeks, fed three times a week, 6 times a day, fed five times a day, five times a week, six Feed 4 times a day after age. Because the chicks have poor digestive functions, they must not overeat. Excessive food can cause indigestion and cause digestive diseases, so you can feed 80% full. From the third week onwards, a suitable amount of clean sand can be mixed in the feed to feed the chicks, so as to gradually increase the digestive capacity of the chicks.

6, to ensure the appropriate breeding density. Guaranteeing the healthy growth and development of chickens is directly related to the breeding density and the occurrence of air, humidity, hygiene and evils in the brooding houses. When the chicks are kept at a high density, the air in the brooding house is contaminated, the ammonia smell is large, the humidity is high, the sanitary environment is poor, and the food is overcrowded; the water rushes to grab the materials, the hunger and food are uneven, the number of broken chicks increases, and the evil spirits are serious and easy to develop. When the rearing density is small, it is favorable for the growth and development of the chicks, but it is not conducive to the full use of the equipment and the rational use of labor. Therefore, the smaller the breeding density of the chicks, the better. The general situation is 30 per square meter in the first week, 25 in the second week, 20 in the third week, 15 in the fourth week, and 10 or so in five or six weeks.

7, do a good job chicken disease prevention insecticide. After the chicks enter the brooding house, use 0.01% potassium permanganate solution as the chick's drinking water to disinfect the gastrointestinal tract. Broilers are more prone to salmonellosis in the early brooding period. Salmonella disease can be prevented by the use of a bacterial enemy (2 millilitres of bacteria added to the enemy by 1 kilogram of clean drinking water). Chicks are susceptible to coccidiosis after 15 days of age, and the use of ball-killing liquid (1 kg of clean water added to 5 ml of ball-killing liquid) can prevent the occurrence of coccidiosis. When chicks are affected by stress factors, 60 mg of succinate can be added to 1 kg of feed for 10 days, or 5 mg of vitamin K can be added to 1 kg of feed to effectively relieve stress. In addition, preventive deworming is carried out once a month, in particular to repel aphids. Drugs such as fleas, insect repellents or insect killers may be used.

Intestinal localization was administered to reduce adverse effects.

Targeted site-specific release:


Two hours in gastric juice will not disintegrate or crack, dissolve within thirty minutes of disintegrating juice, providing a perfect solution for protein and peptide drugs and probiotics.


Enteric coated gelatin hollow capsule is made of gelatin and enteric coating material in gastric juice it will not collapse, but will release in the intestines as a collapse of a target product . It is often used for special packaging of drugs and health cae products which are irritating to the stomach or unstable under acid, or dissolved and effected in the intestine.

Intestinal location administration can improve the efficacy of drugs, reduce the dose and the adverse reaction, brings the convenience to patients. Moreover , it can avoid the degradation of gral protein, polypeptide or health care products and provide the best absorption sites for them.
