Causes and prevention methods of chicken pecking jar

First, reasons

1. The feeding density is too high. The feeding density is too high, the trough and material trough are insufficient, and the chickens compete for water, so that some chickens are lack of nutrition and are prone to pecking.

2. Improper environmental regulation of chicken house. If the air in the henhouse is dirty and the harmful gas exceeds the standard, the chickens will be restless and pecker; the temperature is uneven, cold and hot, which will cause great stress to the chickens.

3. Dietary nutrition is unreasonable. Lack of animal protein in diet, or imbalance of amino acids, chickens can not make effective use of dietary protein, which can cause pecking; lack of calcium and phosphorus, lack of vitamin B2, B3, B6 and B12 can cause pecking.

II. Prevention and control methods

1. Keep reasonable feeding density. Different varieties require different feeding density, and different age density requirements are also different; at the same time, adequate sinks and material troughs should be equipped.

2. Maintain a good environment in the henhouse. The henhouse should maintain good ventilation, remove harmful gases in time, and replenish fresh air, especially in winter, in order to keep warm, ventilation is often neglected. Some henhouses have no heating facilities and rely on the chicken itself for heating. In the hot season, the ground does not pay attention to sprinkling water, resulting in high temperature and low humidity, seriously affecting the survival and growth of chickens. Therefore, it is necessary to give the chickens a suitable temperature and humidity environment to ensure their health and good production performance. The lighting of the chicken house includes natural light and artificial light, and the time and intensity of light should be carried out in accordance with the feeding standards to avoid direct sunlight and uneven light in the house.

3. The proportion of dietary nutrition is reasonable and the whole price is full. The quality of all kinds of raw materials needed for diet should be good. The quality of fish meal is the key, lysine and methionine should be added. Pay attention to the satisfaction of B vitamins. To maintain a reasonable ratio of calcium and phosphorus, when processing diets, the proportion of various raw materials must be accurate, and mixing must be uniform.

4. Broken beak. Beak amputation is an effective method to prevent pecking. The beak was first cut at the age of 7-10 days, and the beak was repaired at the age of 7-8 weeks or 10-12 weeks. When cutting off the beak with a beak breaker, the temperature should be controlled at 500℃, the upper beak should be broken by 1 beat 2, and the lower beak should be broken by 1 beat 3 seconds, and the time should not exceed 2 seconds. Pay attention to stop bleeding, flatten the periphery of the beak with a blade to prevent the external edge of the beak from growing again, and drink VK3 and erythromycin for 3 days to prevent bleeding and secondary infection.

Layer pecking is a common addiction. Enough attention should be given to feeding and management, pecking habits should be analyzed pertinently, and measures should be taken to solve them as soon as possible, otherwise it will bring great losses.
