Bull Quality Requirements
As a kind of meat-type bull, its physical appearance and production performance should be in line with this species of breeder special grade and a standard, after the determination of descendants can be used as the main species of communal animals. Meat performance and reproduction traits are two extremely important economic indicators for meat-type bulls. Secondly, breeding bulls must be quarantined to confirm that they are free of infectious diseases, robust in physique, adaptable to the environment, and resistant to disease. Adult bulls can be harvested twice a week. Each time, two consecutive runs can be performed according to circumstances and needs. Before harvesting, bull penis and foreskin should be washed with warm water and then rinsed with sterile saline. The color of fresh semen should be milky white, yellow, straight forward movement is not less than 60%, sperm concentration is not less than 600 million per milliliter, and the rate of malformation is less than 15%.
The best way to determine the heredity of an individual's bull is to determine the progeny, and it is the most reliable one based only on the performance of the offspring. The same month old son or daughter with several bulls is kept under the same living conditions, and the daily energy gain and digestible protein amount of 1 kilogram per weight gain of the bull's offspring at different finishing stages or during the whole period are measured. After slaughter, the weight of slaughter, the slaughter rate, the net meat weight, the net meat rate, etc. are calculated. Only qualified bulls that are determined by progeny can be used for breeding purposes.
Breeding of bulls
The normal growth and development of the bull, and the age of the species, have a direct bearing on the husbandry and management, especially in young age. For breeding bulls, it is required to have a small feed volume, rich nutrition, good palatability, and easy digestion. Should be fed more protein feed and hay, less fed juicy, carbohydrate feed. Succulent feed and green roughage should generally account for less than 60% of the total nutrients in the diet. It should not be too much, especially for bred bulls. The amount of concentrate and the amount of coarse material in the diet should be appropriately increased to avoid the formation of grass. "Influence of species value. In order to improve the semen quality and sexual function of bulls, appropriate amounts of animal feed, such as blood meal, bone meal, and eggs, should be fed. s Winter should be fed 1.5-2.5 kg of wheat bud or barley malt every day to supplement vitamin deficiency.
Calcium Chloride Description :
Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous. Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature
Calcium Chloride Application :
1. They are widely used in highway, expressway, parking lot and port to melting snow and ice.
2. Used as dryer, as anti-fog, and anti-dust agent also fireproof agent
3. Protective agent and refining agent for petroleum/oil field.
4. Pigment assistance agent of textile. It is a kind of raw material.
5. It acts as flocculation in water treatment.
6. Be used in waste paper processing as removing printing ink agent.
7. As anti-freezing agent.
8. As dehydration agent.
9. Food additive: as cryogen are used in ice cream, as stable agent/coagulant used in bean products, drink and beer.
