Water plays an important role in any organism and has a great effect on laying rate.
The quality of water has more influence on the laying rate, for example, the nitrite content in the water is high, which leads to the ventral discharge of laying hens and the decrease of laying rate and hatching rate. Source of infection for laying poultry diseases, which can cause blight and decrease egg production., it is necessary to provide sufficient, clean and hygienic drinking water for laying birds.
In the quantity production, the laying hens usually use free drinking water, or intermittent and sufficient water supply, which can completely guarantee the water supply. In general, the daily water requirement of each chicken is about 100 ml in winter, 300 ml in summer During the vigorous laying period, the metabolism was strengthened and the water requirement was increased. further, with the increase of chicken food, water demand increased gradually.
In addition, practice shows that chickens also have drinking water peaks. It is observed that the drinking time of chickens is mostly within the illumination time. There are about 3 drinking water peaks every day, which are around 8 o'clock, 12 o'clock and 18 o'clock. In production, most of them are free drinking water, so it is difficult to observe the peak of drinking water. Understand the peak drinking time, you can immunize or administer drinking water during peak hours.
