1, carrot
Carrots are rich in vitamins, especially vitamin A. Feeding carrots to chickens can significantly improve the egg production of chickens. Adding 15% carrot to chicken feed can promote chicken metabolism, energy conversion and egg laying rate, and also improve the effective utilization rate of feed and increase feed reward. According to the experiment, adding 30% fresh carrots to the chicken diet can obviously improve the egg yolk grade.
Feeding method: carrots are washed, chopped and mixed with feed. This method is simple and convenient.
2, leeks
The dry matter of leek contains crude protein 27.5%, metabolic energy 2.38 million calories/kg, crude fiber 10.3%, various trace elements, vitamins and aromatic oils. Feeding chickens with leeks has many functions, such as nourishing nutrition, sterilizing and stimulating appetite. It has obvious preventive effect on a variety of infectious and physiological diseases of chickens. In the epidemic season of chicken plague, the preventive effect of feeding chickens with leeks is more obvious.
Feeding method: Generally, the chicks are fed leeks on the fourth day after eating, and the daily feeding amount is increasing, and each chicken is fed at most 25g per day. Wash leek, dry it, chop it, mix it into feed, and then feed it. The leeks fed to the chickens should be tender and moderate. Too tender leek contains more water, and too old leek contains more crude fiber, which affects the feeding effect.
Step 3: celery
Celery is a good feed for raising chickens. According to the experiment, feeding fresh celery to chickens can improve the egg laying rate 15 ~ 20%.
Feeding method: (1) Each laying hen is fed celery three times a week, about 50g each time; Wherein celery leaves are fed separately, celery stems are chopped and added into compound feed for feeding; (2) Boil1.7kg celery with1.7kg water for about15min, so that laying hens can drink freely. The celery used to feed chickens in this way must be fresh.
Step 4: garlic
Allicin in garlic can enhance the secretion of gastric juice, promote gastrointestinal peristalsis, stimulate appetite, not only increase the growth and appetite of chickens, but also prevent many diseases.
Feeding method: Peel and chop raw garlic and mix it into chicken feed at a ratio of 3%~5%.
5, red pepper
Red peppers contain phytoncide. According to the experiment, adding 0.3% ~ 0.6% Chili powder to the feed for laying hens can significantly deepen the color of egg yolk, improve the feed intake, cold tolerance and disease resistance of chickens, and increase the laying rate by 8% ~ 10%.
Feeding method: red pepper is made into powder and mixed into chicken feed according to the ratio of 1%.
