Problems solved by technology

[0004] However, due to the short artificial breeding time and the limited breeding area of ​​the long-snout catfish, there are few studies on its nutritional requirements for protein, fat, amino acids, trace elements, etc., and the experimental data obtained are not very informative; When using artificial feed, we did not combine nutrition research and processing technology for the characteristics of long-snout squid mouth lower position and slow eating, and the pellets produced are often not the most suitable feed for long-snout squid breeding.

Abstract

The invention relates to a special slow-falling extruded mixed feed for Leiocassis longirostris, and a preparation method thereof. The special slow-falling extruded mixed feed for Leiocassis longirostris comprises, by mass, 30-40% of fishmeal, 15-25% of soybean meal, 5-10% of degossypolized cottonseed meal, 5-15% of corn protein powder, 5-10% of bread flour, 3-5% of cassava modified starch, 3-5% of sea-tangle powder, 1-2% of calcium dihydrogen phosphate, 3-8% of fish oil, 0.1-0.3% of a Leiocassis longirostris multi-vitamin premix, 0.5-1% of a multi-ore premix, 0.1-0.5% of choline, 0.2-0.5% of salt, 0.01-0.05% of an antioxidant and 0.05-0.2% of a mildew inhibitor. The feed has the following beneficial effects: 1, the nutritional requirements of the Leiocassis longirostris are well satisfied, and the growth speed is fast; 2, the feed is suitable for the intake of the Leiocassis longirostris; and 3, the digestion utilization rate is high, the nitrogen and phosphorus discharge is low, and the pollution to water is small.
