How to reduce the breakage rate of eggs
The damage of eggs accounts for 6-8% of the total egg production, which brings great losses to the production of laying hens. Here are some ways to reduce egg damage.
1. To meet the nutritional needs, especially the content of calcium and vitamin D3, and the content of phosphorus should be suitable, and the ratio of calcium to phosphorus should be about 3.4-4.6.
2. Increase the number of egg detection times and avoid colliding with each other, especially in the concentrated time of egg production, and the action should be light when picking up and moving eggs.
3. In the high temperature season, appropriately increase the content of calcium in the diet, the calcium content is between 3.7-5%, do not exceed 5%, and supplement baking soda (0.25% sodium bicarbonate instead of 0.2% salt) and vitamin C (50-100 mg / kg) in drinking water, which can not only reduce the heat stress of chickens, but also improve the quality of eggshells.
4. The number of egg boxes should be sufficient, and the bottom of the cage should be covered with clean and soft cushions. The bottom of the cage should not be too steep, and the lead wire should not be too thick. In order to buffer the impact force of eggs, buffer pads should be used on the inside of the edge of the egg trough and at the landslide turn of the egg collecting line.
5. From the age of 50-60 weeks, the egg production of the short-term hunger strike for 3-7 days was the same as that of the non-fasting group, the eggshell strength was significantly higher than that of the non-fasting treatment, and the egg breaking rate decreased significantly.
6. To keep chickens healthy and free from disease, many diseases will not only reduce the laying rate, but also reduce the quality of eggshell and increase the rate of broken eggs.
7. The damage rate of brown shell eggs is lower than that of white shell eggs when raising brown shell hens with good eggshell quality.
8. Reduce the occurrence of stress factors and keep the environment inside and outside the chicken house quiet and comfortable.

A brief introduction to the main points of prevention and treatment of duck heatstroke
Duck heatstroke, also known as heat stress, is an acute disease caused by disturbance of heat dissipation mechanism and destruction of heat balance in ducks under the condition of high temperature and high humidity. If the disease is not dealt with in time and effectively, a large number of ducks will die, thus causing greater economic losses to breeding. The main causes are as follows: 1. The temperature in summer is too high, or the humidity increases after the rainstorm, and ducks are most likely to cause heatstroke under the combined action of high temperature and high humidity. 2. There are no shading facilities in the duck's sports ground, which makes the duck stay in the strong sun for a long time.

Treatment of stomach stagnation in pigs
Cause: the stomach stagnation of pigs is due to overfeeding after starvation, overeating and overeating, resulting in the accumulation of food in the stomach. Symptoms: loss of appetite or cessation of appetite, sometimes vomiting, vomiting smelly, abdominal bulge, pressure diagnosis abdominal wall solid pain, shortness of breath, body temperature is generally normal. Treatment: prescription 1: take orally with 100ml vinegar and 15g salt. Square 2: green vegetables 250 Mel 500 grams tamping juice, sesame oil 60 Mel 90 ml, mixed internal service (this side is 10 Mel 20 kg pig dosage).
