What are the benefits of feeding ducks?

1 Controlling the growth rate The mother duck has strong depositional fat and good nutritional conditions, resulting in excessive deposition of fat in the ovary, affecting egg production and eggshell quality. By restricting rearing, the mother duck can be prevented from over-fat and overweight. 2 Cost Savings Feed costs can be saved by limiting feeding. 3 Improving the survival rate of laying ducks By limiting the breeding, the diseased ducks and weak ducks that cannot tolerate are naturally eliminated, thereby increasing the survival rate of laying ducks. 4 Controlled mature young ducks develop rapidly under good nutritional conditions and have early sexual maturity, often leading to premature birth, premature aging, and short duration of egg production. By restricting rearing, sexual maturity can be delayed and the ovaries and fallopian tubes can be fully developed. Functional activities are enhanced to increase egg production during the entire laying period.

Jaw Crusher

Laboratory jaw crusher is mainly used for the laboratory, the raw materials in the broken and crushing, such as coal, gangue, coke, limestone, pyrite and so on. The broken way for the song moving extrusion. The maximum size of the material to be crushed should be less than 10-60 mm for the size of the material to be used. Crushing material compressive strength of not more than 100MPa. Equipped with a jaw plate white iron, high manganese steel, wear-resistant alloy several, the price gap, can be broken different hardness of the material. This machine has reasonable design, simple structure, few parts, convenient maintenance and easy operation. No dust leakage, stable performance, low noise, improve the working environment and conditions of sample preparation, it is the ideal equipment for the upgrading of laboratory sample preparation equipment, widely used in electric power, metallurgy, chemical industry, geology and other industries. Preparation of test pieces.
