At present, broiler chickens generally adopt the method of feeding is free to feed any chicken, stay up late to give light, but do not limit feeding, pay no attention to physical training and cultivation, resulting in broiler growth in the late stage, prone to various metabolic diseases , such as ascites, sudden death, and leg problems. In order to prevent the occurrence of these diseases, the farmers have blindly added drugs to the feed. This not only leaves chickens with drug residues, but also increases the cost of feeding and causes economic losses. According to many years of production practice, the author bred the growing period of broilers in three stages and received good results. Now it is introduced as follows: The first stage and the third stage divide the first stage 0 days to 14 days and the second stage 15 days - 35 days of age, the third stage of 36 days to slaughter. Second, the specific steps of each stage 1. The first stage: in the first few days, to give high-quality feed water, such as 5% glucose + super multidimensional + high efficiency and low toxicity antibacterial new drugs, and to provide small, easy to digest full Price compound feed. Generally use small pellets, so do less feed Tim, so that the amount of material occupy the best slot 1/2 or 1/3. In the light, the first day can be used 24 hours of light, light intensity of 4 watts per square meter, then gradually reduce the light time transition to natural light. Gradually decreasing and then increasing light programs can promote the development of chicken internal organs and bone calcification to a certain extent, so that the health conditions are good. At the same time, it brings about late compensatory growth, and the incidence of disease is also low. 2. The second stage: According to the growth of broilers, appropriately increase the volume of feed and reduce the energy and protein concentration in the feed, generally about 10%, but the various vitamins, trace elements and minerals in the feed Supply according to standard or slightly higher than standard. Feeding method: feeding 3 times a day, management, mainly to pay attention to exercise, such as using bamboo sticks to drive chickens at night, can increase the activity of broilers to achieve the purpose of exercising internal organs, but also reduce the pressure on the chest . Appropriately increasing the light intensity is also beneficial to exercise and reduces the incidence of disease. 3. The third stage: To provide high-quality fattening feed, compound feed should pay attention to: 1 diversification of raw materials and low fibrosis; 2 add 3% -5% of animal and vegetable fat; 3 as far as possible using granular materials. The number of feedings is increased from 3 to 5 times a day; or the free-feeding method is used, which requires the chute to be kept constant to satisfy the chicken's feeding. The breeding density must be adjusted in a timely manner. Density is too large to limit the feeding of chickens and affect rest. As a result, the growth and development of chickens is not uniform, and air pollution, excessive humidity, deterioration of environmental sanitation and poor fattening effect are caused. Under normal circumstances, the breeding density is 12-15/m2 in winter and 8-10m/m2 in summer. At the same time pay attention to ventilation, in order to maintain the fresh air inside the house, the temperature is appropriate to about 18 °C, relative humidity of 55% is appropriate.
