Broiler segment feeding technology

Broiler segment feeding technology

At present, broiler chickens generally adopt the method of feeding is free to feed any chicken, day and night to light, although there are stages in the feed supply, but not limited feeding, pay no attention to the cultivation of physical training, resulting in the growth of broilers Various metabolic diseases such as ascites, sudden death, and leg problems are prone to occur later. If the growth period of broilers is divided into three stages, they can receive good results. The three-stage division is based on the physiological characteristics of broiler chickens. Newly hatched chicks have short and thin fluff, and the body temperature is slightly lower than that of adult chicken by about 3°C. After 4 days of age, the body temperature gradually increased and reached the temperature of the adult chicken at 10 days of age. Chicks have a small gastrointestinal volume and poor digestion of food, but they grow rapidly. Based on these physiological characteristics and growth laws, the broiler breeding period is divided into three stages: the first stage is 0 to 14 days old, the second stage is 15 to 35 days old, and the third stage is 36 days old until slaughter. The main feeding technology points in each stage The first stage Since the chicks just transferred from the hatchery to the brooding house, some chickens have been stored or transported for long distances and have been subjected to hunger, thirst, thrills and new living conditions. The main measure at this stage is to adapt the chicks to the new environment as soon as possible, reduce stress, reduce the incidence, and increase the growth rate. Because there is a large positive correlation between 7-day-old body weight and slaughter weight. The second stage chicks have basically adapted to the new living environment and gradually entered the period of rapid growth. The main task of this stage is to improve the chicken population, promote the formation of the chicken body frame, promote the development of internal organs and the robustness of the legs, and lay a solid foundation for the growth and development of this stage, so that the rapid growth of the late, less incidence. Experiments have shown that limiting the feeding of 14-day-old broiler chickens for 3 weeks can improve the feed utilization rate and survival rate, and the restricted growth at this stage can be fully compensated in the third phase. The third stage of the broiler body framework has been formed, and the body is robust and metabolically strong. At this time, the fastest growing rate, the main technical measure is to take all methods to promote the chicken's intake and digestion and absorption, reduce the movement, reduce the body's consumption, so that the maximum rate of feed conversion. The first phase of the specific measures in each phase is to provide high-quality drinking water in the first few days and to provide small, digestible, full-priced compound feed. Generally use small pellets, so do less feed Tim, so that the amount of material 1/2 or 1/3 of the best food trough. When feeding, the first day can use 24 hours light, light intensity of 4 watts per square meter, then gradually reduce the light time transition to natural light. Experiments show that gradually decreasing and then increasing light program can promote the development of internal organs and bone calcification to a certain extent, so that the health status is good, and at the same time it brings about compensatory growth in the later period, and the disease incidence rate is low. The second stage is based on the growth of broilers, appropriately increasing the volume of feed and reducing the concentration of energy and protein in the feed. Generally, it can be reduced by about 10%. However, various vitamins, trace elements, and minerals in the feed should meet the standard requirements. Or slightly higher than the standard supply. Feeding method: feeding three times a day at regular intervals. Management, mainly to pay attention to sports, such as the night with a bamboo rake to drive away the chickens, in order to increase the activity of broilers to achieve the purpose of exercising internal organs, but also reduce the pressure on the chest to stimulate. Appropriately increasing the light intensity can be beneficial to exercise and reduce the incidence of disease. The third stage is to provide high-quality fattening feed, full nutrition, high energy, and eggs can be more suitable. Care should be taken when formulating feeds: (1) Diversification of raw materials and low fibrosis; (2) Adding 3% to 5% of animal and vegetable fats and oils; (3) Feed pellets should be used as far as possible. The number of feedings was increased from the original three times a day to five times, or free-feeding methods were used to keep the feed troughs and feed the chickens. In terms of management, it is necessary to reduce the exercise without affecting the health of the flock and cooperate with low light intensity and long illumination time. It is also necessary to adjust the breeding density in time. If the density is too large, the chicken's intake will be restricted, and the rest will be affected, resulting in uneven growth and development of the chicken and air pollution. Excessive humidity, poor sanitation, and poor fattening. Under normal circumstances, the stocking density is 12-15/m2 in winter and 8-10/m2 in summer. At the same time pay attention to ventilation, keep the air inside the house fresh, the temperature is about 18 °C, relative humidity of 55% is appropriate.
