Amino acid are organic acids containing amino groups, which are the basic units of proteins. There are more than 20 kinds of amino acids that constitute proteins, which are often divided into essential amino acids and non-essential amino acids according to their nutritional needs for pigs and chickens. In pigs, chickens can not be synthesized, or can be synthesized, but the speed and quantity of synthesis can not meet its normal growth needs, so must be supplied by the outside world of amino acids, called essential amino acids. So far, the essential amino acids that have been widely used in the breeding industry are methionine and lysine
Efficacy and function of amino acid for Poultry and veterinary use:
First, Feed Amino Acid improve immunity
Amino acids are important nutrients in animals, which can improve the immunity of animals
Second, promote growth and development
Amino acids also have a positive effect on the growth and development of domesticated animals
Third, improve the efficiency of breeding
There is a certain relationship between animal amino acid intake and feed conversion rate. Reasonable strengthening of amino acid supply can improve feed utilization rate, reduce pollutant discharge and improve aquaculture efficiency

Jilin Nongda discovered the mechanism of anti-ginseng rust disease
Ginseng rust is a widespread and recurring issue in ginseng farming, posing significant challenges to crop health and yield. Recently, a groundbreaking study conducted by researchers at Jilin Agricultural University has revealed that arbuscular mycorrhizal (AM) fungi can effectively enhance ginseng's resistance to rust. This discovery was part of the "Research on the Role and Mechanism of Arbuscular Mycorrhizal Fungi Inducing Resistance to Rust-Resistant Rot Disease in Ginseng," an applied basic research project supported by the Jilin Science and Technology Development Program. The project recently received positive expert evaluation, marking a major step forward in sustainable ginseng cultivation.
The primary goal of the project was to address the problem of continuous cropping, which often leads to soil-borne diseases and reduced productivity. By examining the interactions between five types of AM fungi and ginseng rust pathogens, the team found that *Glomus fasciculatum* significantly suppressed the development and spread of ginseng rust. This finding highlights the potential of AM fungi as a natural and eco-friendly alternative to chemical pesticides.
In addition to its practical application, the research also explored the biochemical mechanisms behind the enhanced resistance. Scientists analyzed the activity of key enzymes such as chitinase and phenylalanine ammonia-lyase (PAL), which are crucial in plant defense responses. They discovered that these enzymes play a vital role in the resistance induced by AM fungi. For the first time, the Class III chitinase gene from ginseng was successfully isolated and subjected to prokaryotic expression and functional analysis. These findings provide important insights into the molecular basis of ginseng's resistance to rust.
This research not only advances our understanding of the complex relationship between AM fungi and plant immunity but also opens new possibilities for biological control strategies in agriculture. With further development, AM fungi could become a valuable tool in managing ginseng rust and other soil-borne diseases, contributing to more sustainable and environmentally friendly farming practices.
