Amino acid balance in chicken feed
The balance of amino acids refers to the balance of essential amino acids. Proteins are composed of various amino acids in a certain proportion. The types, numbers, and proportions of amino acids in different proteins are also different. The balance is to make the types of amino acids in feed and the amount of various amino acids match the requirements, and not to Insufficient or excessive. This can not be done in practice, but it is necessary to strive to make the amount of supply close to the demand, the closer the balance of various amino acids, the more beneficial to the chicken's weight gain, egg production, the higher the feed utilization rate. If there is a lack of essential amino acids, especially restricted essential amino acids, then the use of amino acids is balanced according to this ratio, and other kinds of amino acids cannot be used anymore and are wasted.
The types and amounts of amino acids contained in various feeds are not the same. A feed has more amino acids and less B amino acids. Another feed may have less amino acids and more amino acids. The amino acid content of different kinds of feed differs greatly. The amino acid content of animal feed is higher than that of plant feed. The same kind of feed is not the same, is also a protein-rich oil cake feed, soybean cake lysine content is higher than rapeseed cake, and methionine content is less than rapeseed cake; fish meal lysine content is higher than silkworm cocoon, and The content of methionine and tryptophan in silkworm cocoon is higher than fish meal. If you use a variety of feedstuffs when formulating feeds, you can use supplements to complement each other so that amino acids complement one another. This is an important measure to balance the amino acids, so the feed mix needs to be diversified.
Adding amino acid supplements to your diet is the ideal way to balance amino acids. The method of supplementing is to first calculate the content of the diet, and then add the deficiency according to the purity of the amino acid additive. In recent years, extensive research has been carried out at home and abroad. Many production units reduce animal protein feeds in chicken diets, or do not add animal protein feeds, but use cheaper plant protein feeds, and then use methionine and Lai. The amino acid additive balances amino acids in the diet and achieves better results.
At present, methionine and lysine additives are often used in the chicken industry and are sold by feed companies all over the country. They can be added based on the difference between the food content and the required amount.

In 1892, French missionary father Tian Daneng preached in Dali, Yunnan Province, China. In order to drink coffee, he taught local villagers to grow and drink coffee. Up to now, coffee has been planted in Yunnan Province of China for more than 100 years, with an area of 120000 mu. Most of the varieties planted in Yunnan are ccatimor, with an altitude of 1000-1500m, The coffee produced in Yunnan has a balanced taste, rich nut and citrus flavor, some of which are very sweet, with obvious taste of chocolate, toffee and maple sugar. It is one of the high-quality coffee producing areas. Our coffee is produced at the junction of Puer and Burma - the Myitkyina original jungle beans at 1500-1750, with a rich flavor, high aroma and high sweetness. The 2019 international coffee cup Masters Tournament (China finals) is sponsored by beans.
