1. Vitamin C.
During the hot season, laying hens often suffer from poor heat transfer (no sweat glands), resulting in increased body temperature, rapid breathing, and decreased feed intake and egg production. Vitamin C participates in various metabolisms in the body, which can relieve the adverse effects of heat stress, increase appetite and improve production performance. At a high temperature of 34°C, 200 mg of vitamin C per kilogram of dietary supplementation can increase the egg production rate by 8%, and by adding 300 mg of vitamin C, the egg production rate can be increased by 10%.
2. Tea.
Tea is sweet, bitter, slightly cold and contains a variety of vitamins. In the summer, tea leaves are boiled with boiling water for 30 minutes. Tea juice is water-free for the chicken to drink. Tea slag feed chickens, can heat and reduce temperature, increase egg production rate of 8%, but also anti-inflammatory sterilization, prevention and treatment of gastroenteritis and other diseases.
3. Baking soda.
It is a weak base that has the effect of dissolving mucus, inhibiting acid and promoting appetite. Adding 0.2%～0.3% baking soda to layer chicken diet in summer can not only increase the palatability of feed, increase feed conversion rate, increase egg production rate by 5%, but also reduce heat stress and prevent the chicken from eating improperly. Rumen acidosis and other diseases. Baking soda is cheap and has promotional value.
4. Carrots.
Cool and palatable, nutritious, rich in vitamins and carotene. Adding 10% to 20% chopped carrots to the hen's diet will increase the body weight, increase the egg production rate by 6%, and enhance the ability of the chicken to resist heat.
5. Celery.
Juicy green, heat and dampness, feeding chickens can not only supplement vitamins, but also prevent heat stress caused by loss of appetite, egg production rate can be increased by 10%. Feeding methods: (1) Feed celery once every 2 days, 40 grams each time. Single celery leaves were fed and celery stems were chopped and fed with spices. (2) 1 kilogram of celery add 2 kilograms of water, decoct for 15 minutes, and take the juice for chicken to drink freely.
6. Watermelon skin.
It has the effect of clearing heat and cooling, and producing fluid and dryness. Each chicken is fed 50 to 100 grams of freshly chopped watermelon rind daily, and the egg production rate can be increased by 5%.
7. Green bean soup.
Mung bean heatstroke cooling, detoxification. Take appropriate amount of green beans, add 10 times water after washing, cook until peeling, and let the chicken drink the bean soup, several times a day, the egg production rate can be increased by 10%.
8. Bacitracin zinc.
It can relieve heat stress and reduce heat production in chickens. At a high temperature of 34°C, 100 mg Bacitracin zinc was added per kilogram of diet, the egg production rate was increased by 15%, and the chicken body heat production was reduced by 7%.
9. Aspirin.
Helps the body's heat balance. Adding 0.05% aspirin to the chicken diet can promote chicken body heat dissipation and increase egg production.
10. For fresh cold water.
During the hot season, laying hens often suffer from poor heat transfer (no sweat glands), resulting in increased body temperature, rapid breathing, and decreased feed intake and egg production. Vitamin C participates in various metabolisms in the body, which can relieve the adverse effects of heat stress, increase appetite and improve production performance.
