Keeping broilers paying attention to these details

(1) Choosing Healthy Chick Farmers tend to purchase broilers and chicks mostly from outsourcing, and the purchased chicks are good or bad, which has a great impact on the brooding effect and directly affects the level of aquaculture benefits. In order to improve the survival rate of brooding, we must strictly control the quality of the bred animals and strictly select them so as to ensure the reliability of the provenance, the quality of the chickens and the health of the chicks, and we must not attempt to purchase unhealthy chicks. When selecting chicks, besides paying attention to fine varieties, they must also be guaranteed from non-epidemic areas. In accordance with the criteria of "chicken, hairy, boned, eyeful, lively and active" of the chicks, the method of "one look, two touches and three listens" is used to identify the strengths and weaknesses of the chicks.
(b) to do a good job of chicks insulation moisturizing work The key to the success or failure of brooding is whether to give the appropriate temperature. This is because the thermoregulatory function of the newborn chicks is weak and it is difficult to adapt to changes in the outside temperature. Especially in the winter and spring season, due to the low temperature, if the temperature of brooding is too low, the chicks will be curled up and squeezed to warm each other. They will easily suffer from cold and cause diarrhea or respiratory diseases, even close to heaps, affecting feeding and activities and causing growth. Dysplasia, sometimes squeezing stampede, causing disability, and causing massive deaths when severe.
(c) Adjust the temperature in time
1. The chicks will be piled up next to the heat source during cold stress and will also be squeezed into the feed pan. Intestinal matter is in a watery and gaseous state, excreted feces is light and thin and there is an anal phenomenon.
2. During heat stress, the chick will lie prone on the floor and stretch his head, neck and mouth to pant. The chicks will seek places where the house is cooler and thieves are more windy, especially where they are away from sources of heat along the walls, and crowded around the drinking fountains, so that the body is soaked and the amount of drinking water increases. The hernia sac and the intestines swell due to excessive moisture.
(D) Scientific breeding
1. Brooding period (0 to 3 weeks): The goal is to raise the weight of each week of age at the appropriate time. According to data, 1 gram of body weight at the end of the 1st week will reduce the body weight by 10 to 15 grams. In order to achieve the standard of body weight at the end of 1 week, the first week should be fully reared and fed high-energy high-protein diets, the energy can not be lower than 13.37 MJ/kg, the protein can reach 22% to 23%, and can be in the diet for every 100 Broilers added 4 egg yolks and 100 grams of milk powder, and were supplemented with water for 14 weeks. 2 to 3 weeks of appropriate restrictions on feeding, to prevent excessive body weight, in order to reduce the incidence of ascites, sudden death and leg disease, this period of feed protein can not be less than 21%, energy 12.46 ~ 13.37 MJ / kg.
2. Chicken period (4 to 6 weeks): It is the skeleton forming stage. The main focus of feeding is to provide nutritionally balanced full-price diets. During this period, the protein in the feed should reach over 19%, and the energy should be maintained at about 13.38 MJ/kg.
3.Fattening period (6 weeks to slaughter): In order to speed up weight gain, dietary energy concentration should be increased, and 1% to 5% animal fat can be added to the diet. During this period, crude protein in feed can be reduced to 17%. 18%.
(e) Effectively strengthen management
1. Waste treatment and drug residue control: During the observation of the chickens, it was found that the dead chickens should be scooped out in time for burning or deep burial. Dead chickens should not be stored in the house, feed room or chicken house. Wash your hands with disinfectant after you finish dying. After each batch of chickens were slaughtered, chicken excrement was thoroughly cleaned and transported to a place away from the chicken house.
2. Air environment and light regulation: Commercial broilers have a relatively high density and produce a large amount of exhaust gas (carbon dioxide) and harmful gases (mainly ammonia, hydrogen sulfide, methane, etc.) every day. In order to remove moisture, harmful gases and supplemental oxygen, and maintain a suitable temperature, it is necessary to strengthen the ventilation of the house, reduce the odor and harmful gas concentration in the house, and improve the growth environment of the broiler. When ventilating and ventilating, avoid thieves' wind. According to different geographical locations, different structure of chicken houses, different seasons, different ages of chickens, and different weights, different ventilation methods and ventilation rates can be selected.
The lighting is divided into natural light and artificial light. At present, most broiler chickens are continuously lighted for 24 hours a day, or 23 hours of continuous light for 1 hour darkness, and 1 hour darkness is intended to prevent power outages, enable broilers to adapt to dark environments, and not crowd out birds due to power outages. Windowed henhouses can be artificially supplemented with light during the day, thanks to the natural light of the sun.
(6) Doing a good job of immunization According to the prevalence of local chicken disease, develop an immunization program that is in line with the actual situation in the field, and timely inoculate various vaccines as required. The methods for vaccinating commercial broilers mainly include intranasal eye drops, aerosols, drinking water and muscle (subcutaneous) injections. The selected vaccine should come from regular manufacturers or imported vaccines approved by the competent authorities of the State. It should be tested before use and properly stored and used.
