The quality of chick rearing and management has a great relationship with the breeding rate of chicks and the whole chicken production. Therefore, in the production of chickens, it is necessary to grasp the feeding and management of chicks, increase the breeding rate of chicks, and increase the economy of chicken breeding. benefit. 1. Pre-brooding preparation and brooding methods 1.1. Preparation before brooding One week before brooding, the chicken sheds, cages, utensils, etc. were thoroughly sterilized with formalin fumigation, and 100 drinking liquids and 120 disinfecting solutions were used for drinking fountains and materials. After the tank is sterilized, it is cleaned and ready for use. Within 1-2 days before brooding, the temperature in the house is raised to about 35°C, and the relative humidity is maintained at about 70%. 1.2. Brooding 1.2.1, ground brooding: This brooding method is generally limited to poor conditions, a smaller breeder, simple, low investment, but it should be noted that the chicken's faeces should be regularly removed, otherwise it will infect a variety of chicks Diseases such as: white fleas, coccidia and various enteritis. 1.2.2. Online brooding: This brooding method is easier to manage, clean and hygienic, and can reduce the occurrence of various diseases. 1.2.3. Broiler Cage Brooding: This method is currently a better way of brooding, not only to facilitate management, reduce the incidence of disease, but also increase the number of brooding and improve the brooding rate. 2. Feeding and management of chicks 2.1. Before the chicks of the chicks start eating, they are first fed with 40,000 potassium permanganate solution to disinfect and excrete the meconium and clean up the intestinal tract. The young chicks eat for the first time and the young chicks eat for the first time. They feed the chicks with granule feed, such as Zhengda and Hope, and begin to feed 5-6 times per day. For chickens with weak constitution, they should be fed once in the dark, and then gradually feed 3 to 3 times later. -4 times/day, nutrition indicators for chicks: crude protein 18-19%; energy 2900 kcal/kg; crude fiber 3-5%; crude fat 2.5%; calcium 1--1.1%; phosphorus 0.44% Methionine 0.45%; Lysine 1.05%. The amount of material used for chicks should be based on actual feeding conditions. Chick feeding must be done regularly, quantitatively, qualitatively, and keep drinking water clean. 2.2, the management of chicks 2.2.1, brooding temperature: the level of temperature has a great influence on the growth and development of chicks, it is necessary to strictly control the brooding temperature, brooding temperature to grasp such a basic principle, the early brooding temperature should be high, weak young The brooding temperature should be higher than that of the young chicks. Small flocks are reared higher than the large flocks, and are higher during the night than during the day and darker than the sunny days during the rainy days. In the actual feeding process, if the temperature is appropriate, the chicks are evenly distributed and lively; when the temperature is too low, the chicks neck down, squeeze each other, and pile up and scream; when the temperature is too high, the chicks spread their tongues and open their mouths to pant Increased drinking water. 2.2.2 Brood Humidity: If the humidity of the indoor air is too low, the water in the chicks will be emitted through a large amount of breathing. At the same time, it will easily cause dust to fly and make the chicks susceptible to respiratory diseases; if the indoor air humidity is too high, it will cause harm. The proliferation of microorganisms affects the healthy development of chicks; therefore, the humidity in the brooding room should be maintained at 65-70%. 2.2.3, to maintain normal ventilation: The carbon dioxide content in the brooding room should be controlled at 0.2%, should not exceed 0.5%, ammonia gas content requirements below 10ppm, should not exceed 20ppm, H2S content requirements at 6.6ppm, should not More than 15ppm. When ventilating and ventilating, it is necessary to prevent chicks from catching colds. It is required to improve the room temperature for brooding before ventilating. The ventilation time is best chosen around noon. Ventilation and ventilation should be performed slowly. 2.2.4 Light and Feeding Density: 1- to 3-day daily light, 4- to 5-day 15- to 20-hour/day, 6- to 9-day 16- to 18-hour/day; 10- Day 14: 14-16 hours/day; 15-28 days, 12--14 hours/day; 28--42 days, 8-10 hours/day. Stocking density: 1--2 weeks for 30--40 birds per square meter, 3--4 weeks for 25--30 birds per square meter, 5--6 weeks for 20--25 birds per square meter. 2.2.5, cut off å–™ é› å–™ å–™ å–™ å–™ å–™ å–™ å–™ å–™ å–™ å–™ å–™ å–™ . 2.2.6 Chicken Immunity To prevent the occurrence of various infectious diseases in chickens, Marek, Newcastle disease, infectious bursa, infectious bronchitis, laryngotracheitis and chickpeas should be prepared according to the chicken immunization program provided by the breeder farm. Immunity work.
