The level of broiler production depends critically on the genetic potential of chickens. What is the degree of internal potential performance, in addition to its close relationship with the appropriateness of the living environment, is also closely related to the appropriateness of feeding management. At present, many households pay less attention to feeding management, which affects the growth and development of broilers, causes feed waste, and reduces the effect of feeding. Farmers should do a good job in feeding management from the following aspects to improve the feeding effect of broiler chickens:
(A) to grasp the timing of eating Chicks reached the chicken house, the first drinking water for 2-3 hours, until 1/3 of the chicks have foraging performance or 24 to 36 hours after hatching, too early and late are unfavorable to the chicks . Eating too early can affect the absorption and utilization of yolk in the chicks, causing indigestion and thus affecting the growth and feed utilization of the chicks. In addition, eating too early, chick activity and chicken droppings can contaminate the feed and affect the health of the flock. If you eat too late, the yolk of the chicks will be consumed excessively and the physique will be weak, which will also affect the growth and survival rate of the chicks.
(2) Providing adequate feeding sites Each chicken after 7 days of age should have an at least 5 cm wide feeding position. As the age increases, the feeding position should gradually increase. At 49 days, it will reach about 10 cm. Inadequate food intake will affect the feed intake of some chickens, which can easily cause uneven chicken size.
(3) Adjusting the height of the trough regularly As the age of the broiler increases, the height of the trough should be regularly adjusted. The upper edge of the trough should be level with the back of the chicken or 2 cm higher. Chickens do not have teeth or soft fleas. When digging and drinking, they must raise their heads upwards. When the troughs are set properly, they can reduce the overflow of feed from the mouth and reduce feed wastage.
(IV) Adjust the feeding frequency with the age of 1-3 days, feed once every 2 hours, stop at night for 4-5 hours; reduce the feeding frequency after 3 days of age, 6-8 times per day and night; 4-6 days later Times. The development of digestive tract of chicks is not perfect, there are no teeth, there is less enthalpy, the digestive enzyme secretion ability is not perfect, the digestive ability is poor, so the initial stage should be fed less Tim Tim, with the increase of age, the number of feeding gradually reduced.
(E) Control the amount of each feed each time the amount should not be too much, because the chicken's poor digestion, eating too full, easy to cause indigestion, affecting feed utilization. The amount of daily use should be reasonably calculated and divided equally by the number of feedings. To be added to the last addition, or to stop for a while to add, can not be expected to feed, otherwise it is easy to cause chicken indigestion, picky eaters, affecting the growth and health of chickens, but also easily lead to feed pollution.
(VI) Providing high-quality feed Because broiler chickens have fast growth and development and the digestive function is not very complete, it is necessary to supply digestible, nutritious full-priced compound feeds. Broiler feeding is generally divided into three stages: 0-20 days for the brooding period, 21-38 days for the medium-term, and 39 days for the slaughter for the latter period. Different feeds should be supplied in stages.
(7) There is a certain transition period for refueling. In the feeding process, due to the different nutrients required in different stages, the raw materials sometimes change, and refueling is inevitable. Improper refueling can cause more stress on broilers. Suddenly changing the feed may cause chickens to have digestive disorders, resulting in indigestion, diarrhea, etc., affecting the growth and feed utilization of broilers. Practice shows that if refueling progresses, there will be no impact on broiler production. When reloading, it usually takes 5-7 days to make a transition. The specific practices are as follows: 2/3 of the previous feed (the feed being used) and 1/3 of the next feed (the feed to be replaced) are used for 2 days; One-half of a feed after 1/2, with 2 days; 1/3 of the previous feed, and 2/3 of a feed, with 2 days, and then all replaced with the latter feed.
