The peak period of laying eggs is not only high, but also long. The length of the peak period of laying eggs has a direct impact on our breeding efficiency. Understand the factors that affect the peak period, and then develop the appropriate wording to extend the peak egg production. What is the reason of summer layer yield reduction?
1. The optimum ambient temperature for laying hens is 13-24 ° C, but it is not easy to control this temperature in midsummer. Therefore, the high summer heat on the chicken caused by the greater impact of stress, often lead to laying hens drop in egg production rate, eggshell quality decreased, broken eggs, soft eggs increased.
2. The peak laying period of laying hens is about 25-35 weeks old, and the laying rate can reach 85% . The laying physiology of laying hens is very strong in this period, so it is necessary to make good use of this precious period.
3. If raising chicks in early spring, the peak time of laying eggs is in summer. Due to the hot weather, chickens eat less. Most chicken farms do not take effective measures to prevent heatstroke and cool down the temperature, or have some measures, but it is also difficult to reach the more suitable temperature (18 ° C-24 ° C) during the laying period.
4. Because of the hot weather, it is necessary to use artificial cooling or use fog machine to cool down, so that the humidity in the house increases, E. coli is suitable for growth and reproduction, the chickens are easy to suffer from E. coli disease, which can also make it difficult for layers to reach the peak of egg production.
HOW TO PREVENT AND CONTROL SUMMER LAYING HEN production reduction?
(1) reduce the feeding density, ventilation and temperature, reduce the radiant heat.
(1) use light-colored materials to make the roof and the wall surface of the house. Enhance ventilation and air flow ventilation cooling: install ventilation facilities, increase the fan operation time, shorten the ventilation interval time, and hanging a wet curtain to reduce the chicken house temperature. Naturally ventilated coops should have all vents open for maximum ventilation.
(2) to adjust the nutrition of feed and increase the quality of chicken colony, 2% ~ 3% oil should be added in the Diet, and the balance of protein and amino acid should be paid attention to. The contents of soybean meal and restrictive amino acids (methionine, lysine) were increased appropriately. The protein was mainly added with plant protein, and the methionine content was increased (20%) . According to weight and physical condition, increase vitamin dosage.
