With the continuous development of feed industry, the nutritional composition of compound feed is becoming more and more complex, which changes the original flavor of feed and affects the feed intake of fish, and seasoning is an effective measure to solve the palatability of feed.
Advantages:
- Increase fish appetite, promote digestion and absorption. Palatability depends on the taste of the feed, through seasoning, but the feed has the smell of fish like, stimulate the sense of smell, promote the secretion of digestive juices, gastrointestinal peristalsis to produce appetite, so as to promote eating behavior.
- Agricultural and sideline products such as cottonseed cake and rapeseed cake in feed are raw materials with poor palatability, and some additives, such as vitamins, drugs and minerals, will also change the taste of feed itself, affecting the taste of feed, while seasoning can cover up the odor and promote eating.
- To maintain the feeding of animals under stress. Because the fish in different growth stage is different to the requirement of feed, often change, so the feed formulation recipe change will cause the change of feed flavor, this is bound to affect the fish food intake, use seasonings can make different feed with the same taste, tempted to feed the fish, to adapt to the change of the feed, to maintain the original food intake.
- Stimulate the secretion of digestive fluid and improve the absorption rate of nutrients. To stimulate the taste of fish through seasoning, reflect to the digestive system, cause the secretion of gastric juice, intestinal juice, bile, so as to improve the content of protease, amylase, lipase, accelerate gastrointestinal peristalsis, increase digestive movement, promote the full absorption of nutrients in the feed, promote growth and development.
- It is beneficial to develop new feed resources and reduce feed cost. Seasoning can develop unconventional raw material resources, expand the comprehensive utilization of agricultural and sideline products, and reduce raw material costs.
