Lachance Nutrition ｜Whether low protein diet technology in the poultry industry can be effective？

In traditional feed formulations, soybean meal is widely used as the main protein source due to its rich protein content and ideal amino acid composition. However， many countries, including China, are highly dependent on soybean imports due to insufficient soybean planting resources.

In addition, the international trade situation and the impact of climate change have led to rising soybean meal prices, which in turn have had a serious impact on feed production costs and the price of livestock and poultry products.

To solve these problems, without affecting animal production performance, many countries are looking for better ways to replace soybeans. The application of low protein diet is one of the most discussed solutions to the problem.

The high crude protein level in the traditional corn-soybean meal diet leads to the low utilization rate of nitrogen in the animal body, and the nitrogen emitted from animal breeding is easy to causes environmental pollution. A large number of studies have shown that low-protein diet combination technology is an effective means to mitigate nitrogen emissions in livestock and poultry. Studies have also shown that reducing the crude protein level of broiler diets from 23% to 19%, while supplementing essential amino acids, can significantly reduce the content of nitrogen, ammonia, and uric acid in feces. It has been proved that low protein diet technology is one of the effective means to reduce environmental pollution.

The premise of applying a low-protein diet is to ensure the production performance of animals. The gut is an important place for the digestion and absorption of nutrients. The fermentation of proteins by gut microbes partially produces metabolites with potentially toxic effects on poultry health. These metabolites can disrupt the intestinal barrier and induce intestinal inflammation. In addition, many anti-nutritional factors in soybean meal will interfere with the digestion and absorption of other nutrients but also harm the intestinal health of livestock and poultry.

Studies have shown that reducing crude protein levels in laying hens' diets by 2% and supplementing them with 0.3% threonine can improve gut flora diversity and increase the abundance of potentially beneficial flora. Therefore, the use of low-protein diet technology plays a positive role in maintaining the intestinal health of poultry.

A low-protein diet is also important in improving the quality of poultry meat. Studies have shown that a 3% reduction of dietary crude protein level and supplementation of isoleucine can increase pectoral muscle pH 24 h, increase muscle fiber density, reduce drip loss, muscle fiber diameter, and shear force, and improve muscle quality in broilers.

The application of low-protein diet technology in poultry production can solve the shortage of protein resources to a certain extent, maintain the intestinal health of poultry, improve the quality of poultry meat, and reduce the nitrogen emission of animal husbandry without affecting production performance.

At present, China's low-protein diet technology has achieved initial results. Lachance Group also attaches great importance to the promotion of low-protein diet technology in the industry, constantly invests in scientific research and innovation, and continues to specialize in low-protein diet technology and soybean meal replacement programs.

After years of practice and accumulation, the feed additive bile acid developed by Lachance Group has shown advantages in low-protein diet technology. Studies have found that bile acid can help improve the activity of digestive enzymes, promote protein digestion and absorption, reduce the protein level by 1% in the formula, and improve the digestion and utilization of fat-soluble vitamins. While protecting the production performance of poultry, it improves breeding efficiency and provides low-protein nutrition in the real sense for the poultry industry.
