-Select the appropriate chicken cage based on the breed and weight of the chickens

The cage is a life and work workshop for chickens. Choose the appropriate cage according to different breeds of chickens, especially the broiler breeders are relatively heavy. The cages for broiler breeders are specially made, and the angle of the egg at the bottom of the cage must be accurate. , Small angles ca n’t roll out eggs in time, they may be damaged by chickens, large angles are easy to fall to the ground and broken or the eggs are rolling with large impulse and they break each other. The general slope of the cage bottom should be kept at 7-8 degrees . The spacing of the iron bars at the bottom of the cage is also very important. It is generally recommended that the spacing is 2.5 boxes × 5 cm. It is wrong to think that the size of the broiler breeder can increase the spacing. It is recommended that conditional chicken farms lay a plastic mesh on the bottom of the cage that is consistent with the mesh at the bottom of the cage. Practice has proved that the plastic mesh can cushion the force of the eggs hitting and rolling down the net, which not only greatly reduces the breakage rate, but also can Reduce the incidence of leg problems and thoracic cystitis. In addition, the treatment of the connection between the cage and the bottom net of the cage should also be done carefully, and there should not be a large gap. There are many eggs falling here. You can use plastic cable ties, thin wires or strings to make cross-wound windings. Wooden or iron baffles can be added to the cages at both ends of the chicken house to prevent them from rolling to the ground. The selection of chicken cage production materials is also very particular. To choose suitable and tough materials, the diameter of the wire at the bottom of the cage is about 2 mm, and the egg breaking rate is the smallest. The larger the wire diameter, the more likely it is to cause egg breaking.

Choose a more suitable breed

At present, the blue-brown, blue-brown, and roman brown are very good breeds in laying hens. They have very stable performance from ancestors to commercial generations, and their anti-stress and disease resistance have been continuously improved. The hardness and strength of the egg shell are relatively good, and the ratio of egg to egg is suitable, especially the ratio of egg white to egg white can reach 1.6: 1. The peak parent generation of egg production is about 94%, and the commercial generation can reach about 96%. Because Hailan Bai is small and saves space, it is very loose to raise three in one cage. Meat varieties AA +, ROSS308, etc. are all better choices, the quality of breeding eggs is better, and the quality of eggshells is better.

Three guarantee feed nutrition balance

The nutritional level of the feed is directly related to the strength and hardness of the eggshell, and is an important factor affecting the broken egg rate. When preparing the feed, it is necessary to equip the feed with comprehensive nutrition in stages, especially calcium, phosphorus, vitamin D3 and crude protein. Although today's feeds are mostly called full-price feeds, in view of factors such as storage and the fact that caged chickens cannot get more vitamins from litter, it reminds us that those farmers who can feed some green feed can get more qualified. egg. There are also breeder farms that replenish multidimensional and minerals twice a week. Excessive nutrition is not always good. For example, too much magnesium can compete with calcium. High manganese can inhibit zinc absorption and is not conducive to eggshell quality. Therefore, when breeder chicken breeders consider the impact of nutrition on the eggshell, Remember to grasp the overall situation and pay special attention to nutritional balance.

Four increase the number of eggs and improve the quality of eggs

According to the size and cage of the chicken, single cages usually raise 2 to 4 chickens, broiler breeders generally 2 chickens per cage, egg breeder chickens 3 per cage, and commercial layer chickens 3 to 4 per cage. Based on an average of one egg formed per day, each cage can pick up 2 to 4 eggs per day. To prevent the eggs from colliding with the eggs and being trampled by the chickens at the bottom of the cage, pick the eggs 6-7 times a day, and the last time to pick the eggs before turning off the lights at night to reduce the time the eggs stay on the cage and prevent pecking. Addicted chicken pecking eggs. Egg picking is usually arranged 3 to 4 times in the morning and 2 to 3 times in the afternoon. It is generally believed that 10% of the total number of eggs picked on one day means that the number of times needs to be increased. The quality of egg picking includes the training of the breeder, the awareness of egg picking, and the requirements for the action of egg picking. Whether using a paper egg tray or a plastic egg tray, the egg must have the big head (with air chamber) facing up and the small head facing down. First, according to the physiology of eggs, it is conducive to the respiration of the embryo. In particular, the breeding of eggs is more important. Qualified eggs are picked separately. Dirty eggs are placed separately after special treatment. Defective eggs (broken eggs, double yellow eggs, deformed eggs, sand shell eggs, soft-shelled eggs, etc.) are collected separately. Pick. When collecting qualified breeding eggs, the intensity must be slow. The eggs themselves are fragile and must be handled lightly. The egg tray and the egg tray must be careful when they are stacked, and they must also be careful when handling.
