Six ways to prevent chicken from wasting feed
1. Use full-price compound feed to improve the absorption and utilization rate of feed. It is undoubtedly the biggest and imperceptible waste to increase feed intake to make up for the incomplete nutritional composition of diet. feed must be prepared scientifically according to the physiological characteristics and growth and development of chickens (broilers and laying hens).
2. Feed crushing should not be too fine. Too fine feed is not only unsuitable for feeding, but also increases dust, resulting in a waste of feed.
3. Improve the trough to prevent feed waste. To provide a reasonably structured trough according to the age of the chicken, we should try to keep the chicken from entering the trough, and at the same time do not let the chicken peck the feed out of the trough.
4. Improve the feeding method and feed less frequently. The feeding amount should not exceed 1/3 of the trough depth. Not only let the chicken have enough to eat, but also can not let there are leftovers in the tank.
5. Pay attention to preservation. Prevent feed from mildew and deterioration, rats and insect pests, rain and direct sunlight, etc.
6. Eliminate low-yield chickens, discontinued chickens and older chickens in time.
