First, the trough structure and placement height should be reasonable. If the trough is too small or too shallow to spill, it will cause waste. If the trough is too large or too deep or placed too high, it will affect the feeding and growth of the chicken. In general, it is advisable to place a height of about 2 cm above the back of the chicken. Second, the amount of feed should be appropriate. According to statistics, the wastage rate of feed added to the tank at 2/3 is about 12%, about 5% at 1/2, and about 2% at 1/3. Therefore, it is advisable not to exceed one-third of the depth of the manger for each feeding. Third, timely interruption. Chicks are cut at 6-9 days, which can effectively reduce feed wastage and prevent the occurrence of chicken gizzards. Fourth, regular weighing. For chickens that are overweight, there is no restriction on feed. This will not only affect the egg production rate but also waste feed. Therefore, the birds need to be weighed from time to time and reared separately according to the size of the chicken. Fifth, science storage feed. Especially in summer and autumn, the feed is susceptible to moisture and mold deterioration, or the value of feed is reduced due to increased fat oxidation, resulting in waste. Therefore, store feeds should be protected from light, ventilation, moisture, and insects, and feed as little as possible during the rainy season. Sixth, feed must be full price, nutrient balance. Chickens cannot absorb nutrients in feed without limit. If the feed mix is ​​unreasonable, too much nutrients can only be wasted; if the feed is too thick, the feeds with different grain sizes will be quickly eliminated from the body after being eaten by chickens. Causes waste. Therefore, full-price feeds should be used rationally, such as self-ingredients, and they must be formulated in strict accordance with the standards. Seven, regular deworming. The infection of parasites by chickens directly affects the absorption of nutrients. Therefore, in general, chickens need to be repelled once every 60 days, and they need to be repelled again before they start production. 8. Prevention and control of bird, rat and animal pests. Rats and birds not only spread diseases but also eat large amounts of feed. Therefore, we must do a good job of preventing and controlling bird and animal pests on a regular basis. Nine, at any time to eliminate sick chickens and low-yielding chickens. Ten, chicken house temperature should be appropriate. In winter, when the temperature is too low, chickens need to increase calories by increasing feed intake. The amount of feed loss is about 10%, causing waste. Therefore, winter insulation and summer cooling are also important.
