Application of starch in the aquaculture industry

      In the aquaculture industry, starch hydrolysis is gradually emerging, playing a key role in improving aquaculture efficiency and promoting healthy animal growth. As a substance that can efficiently decompose starch, the application of starch in the field of aquaculture has injected new vitality into traditional farming models and brought about many positive changes.

      In the field of feed, starch hydrolysis can significantly improve the utilization rate of feed. Livestock and other animals have certain limitations in their ability to digest and absorb starch, and the starch in traditional feed is difficult to fully utilize, resulting in nutritional waste. The addition of starch can break down the large molecular starch in feed into small molecular sugars, making it easier for animals to absorb in their intestines. For example, adding an appropriate amount of hydrolyzed starch to pig feed has been shown through experiments to increase the digestion rate of starch in feed by 15% -20%. This means that the conversion rate of feed can be improved, the breeding cost can be reduced, and the animal growth rate can be accelerated, resulting in more significant weight gain. Within the same breeding cycle, better slaughter standards can be achieved.

      From the perspective of animal intestinal health, starch digestion is also essential. The intestine is an important site for animal digestion and absorption, and maintaining intestinal health is crucial. The small molecule sugars produced by the decomposition of starch can serve as nutrients for beneficial microorganisms, promoting the proliferation of beneficial bacteria such as bifidobacteria and lactobacilli in the intestine, and inhibiting the growth of harmful bacteria such as Escherichia coli. When the balance of gut microbiota in animals is maintained, the integrity of the intestinal mucosa is protected, the secretion of digestive enzymes is more stable, the digestive function of animals is enhanced, and the incidence of intestinal diseases such as diarrhea is significantly reduced. In poultry farming, the use of feed containing hydrolyzed starch significantly improves the intestinal health of chicks, with a survival rate increase of 8% -10%.

      In addition, starch hydrolysis can also enhance animal immunity to a certain extent. When the intestinal health of animals is guaranteed, nutrient absorption is more sufficient, and their own immune system can also receive better support. Research has found that animals fed with starchy feed have increased levels of immunoglobulin in their bodies, enhanced white blood cell activity, and significantly improved resistance to common diseases. In cattle and sheep breeding, after the use of feed additives containing starch, the incidence rate of cattle and sheep in the face of seasonal infectious diseases has decreased by 12% -15%, reducing the use of drugs, and improving the quality and safety of livestock products.

      The application of starch in the aquaculture industry plays an indispensable role in optimizing feed utilization, maintaining animal health, and improving growth performance. With the continuous development of aquaculture technology and in-depth research on starch hydrolysis, it is believed that starch hydrolysis will have broader application prospects in the future aquaculture industry, and will continue to contribute to promoting the green and efficient development of the industry.
