Group of laying hens daily observation five-character policy

Daily observation plays a very important role in the feeding and management of laying hens. Careful and meticulous daily observation can accurately grasp the dynamics of the flock, promptly identify existing problems, and take scientific measures to reduce feeding costs and increase economic efficiency. After more than ten years of production exploration, the author summarizes the five-character principle of daily observation of laying hens, namely, “see, hear, touch, check, and decide”.
1. Look through the observation of the intake, drinking water, egg production, feces, mental status and the main appearance characteristics, grasp the overall situation of the chickens, and find problems in a timely manner.
(1) Feed intake and drinking water: Healthy high-yielding chickens showed strong appetite and fast food intake. The weight ratio of normal drinking water was 1:2 to 2.5. When the diet formula and air temperature are basically stable, if the feed intake of the flock is increased, it will indicate that the egg production will increase; if the feed intake of the flock is reduced, it will indicate that the egg production will be reduced or the chickens will have latent disease.
(2) Egg production: Observed mainly from the aspects of egg weight, egg production rate, and egg shell quality. After the start of production, the egg weight should increase steadily and increase slowly after 35 weeks of age. If the weight of eggs is found to be reduced, all other aspects are normal and may be related to the quality of the diet. The egg production rate of the flock is generally peaked at 28 to 32 weeks of age (above 96%), stabilized for 4 to 5 weeks, and then slowly decreased (0.2% to 0.5% per week). If the drop is abnormal, it should be analyzed from the aspects of disease and feeding management. Egg shells should be dense and well-balanced, the colors conform to the characteristics of varieties, and the surface is smooth and free of spots. The problem of eggshell quality is generally related to disease, diet, and fright.
(3) Faeces: Normal feces should be soft and hard to form, gray-brown, with a small amount of white urate on the surface, no special odor. If there is any abnormality in shape, color or odor, analysis should be made from aspects such as diet, disease, management, and environmental temperature.
(4) Mental Status and Appearance: The healthy and productive chickens are lively and spirited. When the breeder enters the henhouse, the performance is quite exciting and there is appetite. When the anomalous person enters the chicken coop, the performance is highly vigilant and has a fear. The appearance of the high-yielding chickens is short and thick, slightly curved, and the upper and lower jaws are aligned; the eyes are round and full of gods, and are located in the center of the face, which is sensitive to reaction; the face is thin, short, and thin, most of the face is bare, and the color is bright red; the crown is big and bright red. , Soft tissue, no wrinkles. If the spirit and appearance are abnormal, there may be diseases or low-yielding chickens.
2. Listening can be done once every 7 to 10 days. Generally, you have to choose the evening. After turning off the lights, wait until the chickens are quiet, gently step through the chicken coops and listen carefully for 20 to 30 minutes.
(1) Listen to the sound of respiratory tract: Under normal circumstances, the sound of breathing of the flock should not be heard. If there is a snore or snoring, cough, sneezing, etc., it indicates that respiratory disease has occurred.
(2) Whether or not to hear it: Strange calls often occur in high temperature, poorly ventilated chicken houses. In the high-yielding chickens, the chickens were normal during the day and died at night. If the dead chickens were dissected, more than 95% had hard shell eggs inside the fallopian tubes. Strange chickens often show unilateral or bilateral paralysis. If they are picked out in time, properly ventilated, and treated with a small amount of antibiotics, these chickens will generally return to normal after laying eggs. This phenomenon is taken to strengthen the ventilation of chicken houses, increase the content of multi-dimensional diet, and adjust the ratio of calcium and phosphorus, which can be alleviated.
(3) Whether there are animal pests or thieves: In this regard, special attention should be paid to areas with poor mountainous conditions and poor public security. Practical preventive measures must be taken.
3. The first step is to randomly pick out some chickens from the cage for touch inspections, and also to perform touch checks by looking at and listening to individuals who are suspicious. The focus of the examination was on body temperature, body weight, chest, abdomen, pubic space, and whether or not the anus and the leg were injured. Grab the chicken correctly, and try to avoid disturbing other chickens.
4. To investigate the problems of seeing, hearing, and touching, it is necessary to carefully and accurately analyze the causes and, if necessary, use laboratory diagnosis.
5. Determine the improvement plan or treatment measures for the cause of detection. The determination of plans and measures must follow the principles of timely, accurate, and simultaneous treatment to ensure good results.
In summary, although there are many factors that affect the production performance of layer chickens, the daily observation of chickens must not be ignored. If this work is done well, we will be able to identify the entry point for the management of flock and lay the foundation for improving its overall benefits, and it will also help managers to accumulate breeding experiences.
