Ways to prevent degradation of breeder chickens
First, the amount of matching
With good flocking, without proper matching and random distribution, the resulting offspring will not be good. Therefore, in the same breed of chickens, one out of every 8 to 10 hens picks a particularly good cock and has unique and excellent properties, such as fertilization rate, hatching rate, strong disease resistance, or a distinctive appearance. The advantage of using this rooster is to select hens with similarly good traits for mating. This matching result will significantly increase the production performance of offspring.
Second, purification and selection
There are many excellent varieties of chickens, and chickens of a variety that are adapted to local natural conditions, production performance, and economic value are popular in the region. Practice has proved that it is better to promote a variety in a region, so that the speed of development is rapid, the effect is significant, and it is not easy to mix. At the same time, if the chickens with disordered coats, premature moulting, too late egg production, and particularly small eggs are found, they should be transferred or eliminated immediately.
Third, build a hatching brooding point
In areas where the breeder chickens are promoted, hatching and brooding sites are to be set up in key farms, hatched eggs of the improved breeds will be hatched at the point, and raised for about 10 days before being sold to the farmers for feeding. At the same time, they should also be taught to breed chickens with scientific management and disease prevention techniques.
Fourth, strict selection of breeding chickens
When the imported breeder chicken reaches a certain number, the local inferior breeder chickens should be gradually eliminated, from less to more, from rooster to hen, and finally all replaced by improved breeder chickens. In the process of achieving improved seedlings, attention should also be paid to the selection of breeding chickens. In particular, the selection and breeding of breeding roosters should be strengthened, and identification of improved varieties should be carried out. Gradually breeder chick breeding systems should be gradually established so that excellent and productive chickens can be sustained for a long time. keep it up.
Indented cylinder separator is used for length grading of all granular materials, such as wheat, oat, maize, rice, fine seeds, lentils, sticks from sunflower or sugar beet, plastic particles, etc., as well as for the extraction of unwanted short or long admixtures.
Through the inlet housing, the granular material to be graded flows into the interior of the rotating cylinder, whose cover is equipped with special deep-drawn teardrop or spherical-shaped pockets for the most precise length separation. The rotating speed, rotating direction and the size of the dimple will be decided by size and impurities in different processing materials.
