With the arrival of summer, it entered the hot season. The hot weather and rising temperatures have made it a new test for farmers who use poultry farming equipment to raise laying hens. High temperature will seriously affect the growth and production performance of laying hens, resulting in a decrease in egg production and a decline in the economic benefits of farmers. So what is the way to ensure high-yield laying hens in summer? The author will introduce the farmers.
1. Ventilation and cooling of the chicken house: High temperature is an important key to affect the normal performance of laying hens. Therefore, the key point for keeping the laying hens high in summer is to create a comfortable production environment for the laying hens and to cool the chicken houses. It is recommended that farmers can choose to use chicken farming equipment – wet curtains and fan equipment to cool and cool the house. The cooling effect is good, and it is easy to operate. It is the cooling method of many closed houses.
2. Improve feed conversion rate: In summer, affected by high temperature, laying hens will reduce feed intake much more than in the past season. According to experimental data, when the temperature in the house is higher than 25 degrees Celsius, the temperature is increased by 2 degrees Celsius. Will be reduced by about 3 percentage points. Therefore, the proper addition of a part of the micro-ecological products during the summer season is of great help to improve the conversion rate of the feed, or the premix of the micro-ecological enzyme preparation can be selected by the breeding plant using the mixer. It is not recommended to use full-price materials in summer high temperature (the internal composition is unknown, and there is a hidden danger in the mildew of the raw materials). The feeding time is adjusted from 10:00 pm to the next morning, and the brightness of the light is increased appropriately to improve the excitability of the laying hens, preferably 4~5 times.
3. Ensure adequate and healthy drinking water: When the temperature rises in summer, the breathing rate of the chicken is accelerated, the amount of water evaporation is large, and the amount of drinking water is also increased. Ensuring adequate drinking water is a key condition for maintaining body balance at high temperatures. It is also recommended to drink deep well water. First, the temperature of the deep well water is low, and the second is that the probability of deep well water being polluted is small.
4. Add anti-stress additives: high temperature is a big stress for laying hens, so it is necessary to add anti-stress additives to the feed of laying hens or to choose Chinese herbal medicines. Premixing prevents the onset of high temperatures from causing damage to the acid-base balance in laying hens.
