Shandong Qingfeng | Six Nutrients for Beef Cattle Breeding
Release time:
2021-01-06
Calcium and phosphorus in cattle are the main components of bone. Cows need a lot of calcium and phosphorus from the growth and development of the fetus, especially lactating cows and cows in the last two months of pregnancy need more calcium and phosphorus. While the feed ratio is reasonable, the licking of the licking bricks must be increased to supplement various trace elements and minerals required by the cattle.

To raise beef cattle, we must first understand what nutrients they need. The six major nutrients necessary for beef cattle are introduced as follows:
Protein is an indispensable material for beef cattle to maintain life, growth and reproduction. In the process of beef cattle's growth and development, fattening, milk production, etc., all parts of the organization must continue to use protein to grow, repair and update; the production of semen, the production of sperm and eggs, and the secretion of milk all require protein. Protein can also be converted into calories in cattle like carbohydrates and fats to meet the needs of cattle to maintain life and the growth of meat, skin, and hair; while carbohydrates and fats cannot replace the function of protein. Therefore, protein is the most important nutrient, and it is also a nutrient that cattle are more likely to lack.
Carbohydrates in the feed are the main source of energy for beef cattle. After it enters the body of the cow, it is burned (oxidized) and turns into heat, which becomes the energy for beef cattle to breathe, exercise, digest, absorb and maintain body temperature and other life activities. Some of the remaining carbohydrates are then converted into fat in the cattle and stored as an energy reserve in case of hunger. Carbohydrates cannot be converted into protein in cattle. If the supply of carbohydrate feed is insufficient, the fat stored in the cow's body will be used passively to meet the cow's energy needs.
Bovine tissues and organs contain fat. The effect of fat on cattle, one is the best form of energy supply and energy storage in the body; the other is the solvent of fat soluble vitamins. Fat-soluble vitamins A, D, E, and carotene must be transported with fat as a solvent. When fat is lacking, it will affect the absorption and utilization of these vitamins.
In addition, the lack of fat calves, will slow down its growth and development, digestive system dysplasia. But in general feed, forage widely contains fatty acids, so generally not lack.
Calcium and phosphorus in cattle are the main components of bone. Cattle need a large amount of calcium and phosphorus from fetal growth and development, especially lactating cows and cows in the last two months of pregnancy need more calcium and phosphorus. While the feed ratio is reasonable, the licking of licking bricks must be increased to supplement all kinds of requirements for cattle.trace elementand minerals.
When calcium and phosphorus are lacking, the early symptoms are decreased appetite and eating mud, bricks, wood and other things. Cattle and cattle often lick each other's fur and bite their ears. The weight gain rate slows down and the milk yield decreases. If the cow is deficient for calcium, phosphorus or the proportion of calcium and phosphorus is improper for a long time, the cow will slowly lose weight, stop its growth, develop abnormally or be in estrus, and repeatedly match infertility, it can cause paralysis of lame, pregnant or lactating cows, and is prone to fractures.
Salt is both a condiment and a nourishment. It can improve the palatability of feed, increase appetite, help digestion, and improve feed utilization. It is one of the indispensable mineral supplements for cattle.
When cattle lack salt, it is characterized by a thirst for salt, licking salty foreign bodies, loss of appetite, coarse hair, dull eyes, slow growth, and decreased weight and milk production.Rocky Lick Brick
Insufficient drinking water for beef cattle will directly affect weight gain, and long-term water shortage will endanger life.
Generally, lactating meat calves need 5.4-7.4kg of water to feed one kilogram of dry matter. When the water demand of young cattle and adult cattle is below 10 ℃, it takes 3-3.5kg of water for every kilogram of dry matter they feed. When fattening cattle are mainly fed with compound feed, they need about 30kg of water every day in summer and autumn.
