Core Tip: In the open season of meat breeder chickens, in addition to requiring more eggs, higher qualification rate of eggs, low material consumption, high survival rate of breeders, high fertilization rate of hatching eggs, and robustness of hatched chicks, meat use Breeding and management of breeders must pay attention to prevent over-fertilization and maintain good body condition and reproductive performance of breeders in order to obtain more robust offspring.
The raising of meat breeder chickens in the open season requires not only high production of eggs, high rate of breed eggs, low material consumption, high survival rate of breeders, high fertilization rate of breeders, and robustness of hatched chicks. Management must pay attention to prevent over-fertilization and maintain good body condition and reproductive performance of the breeder to obtain more robust offspring.
Meat breeders generally have an egg production rate of 5% at 24 weeks of age, at which time they are called open production. After the chickens start production, the egg production rate rises linearly and the body weight and egg weight gradually increase. While raising the egg production period, the nutritional needs of the laying eggs are taken into consideration. On the other hand, the weight of the hens is prevented from being too large and the fat is too much, which affects the production and reproduction of eggs. force. Therefore, “quantitative feeding†can be used to gradually increase the level of dietary vitamins, proteins, energy, calcium and phosphorus, or the level of nutrition, and gradually increase the amount of feed until the peak of production.
When the egg production of laying hens lasts for several weeks and stays at a relatively high level, the egg production rate will slowly decline, but the egg weight will still increase, and the total egg production weight will not change much, and the body weight will still increase. In order to prolong the peak period of egg production, the egg production rate will decline slowly. Therefore, after the peak period of egg production, it is necessary to maintain the amount of feed that will not change in a few weeks. In the future, the egg production rate will decrease by about 1% per week. At this time, weight gain will be slow. To keep egg production and fertility at a relatively high level, it is necessary to gradually reduce the material or to lower the protein level in the diet so that the nutrients can be maintained and laid. However, the reduction should not be too much, otherwise it will cause the egg production rate to drop, or cause part of chicken moulting. At this stage of laying hens, calcium and vitamin D3 levels must be increased because of the reduced ability to absorb calcium. Otherwise it will increase the number of soft shell eggs, thin shell eggs, and egg breakage.
Egg production period
The “quantitative feeding†amount varies depending on the egg production rate, body weight, and ambient temperature of the laying hens. However, if the amount of feed is increased before the egg is increased, if the amount of feed is insufficient or not increased, the amount will not be sufficient. There will be a peak period of egg production, or the peak period of egg production can not be sustained. Quantitative feeding is also a restricted feeding method, which requires less feed intake than in the past. Therefore, it is required to feed it once in the morning or feed it continuously so that it can be eaten in the morning. Indiscriminate feeding, to prevent snatching and hunger inequality.
Ready-to-eat cereal flour is usually fried, beaten into a powder, and then placed in a jar or bag. Like pearl barley red bean powder, pearl barley can go wet, red beans can fill the heart; Work overworked, eat 2 spoons, can keep in good health, but also relieve hunger!

When it's ready, put it into a bowl and serve, one bowl at a time.
There are many kinds of ready-to-eat cereal powder: red bean, job's tears, black rice, yellow rice, green bean, black bean, mung bean, white bean, soybean, wheat, Gordon euryale, black sesame....... And so can be baked grinding, direct consumption.
Whole grain flour can be eaten in two ways. One is cornflour and the other is cooked flour. Cornflour can be added to cold water, cooked after eating; Cooked powder can be served directly with boiling water. Our category is ripe grain powder, ready-to-eat grain powder, can be a single variety of grain grinding, can also be a plurality of varieties of mixed grain grinding, support custom, send samples.
