Embodiment

[0020] Embodiment: A combination of sinking and extruded compound feeds for long-snout squid, characterized in that: the feed combination includes sinking and puffed compound feeds, which are successively suitable for juvenile feed for three growth cycles of long-snout squid, Juvenile fish feed and adult fish feed, the weight ratio of protein in the juvenile fish feed is 50-70%, the weight ratio of protein in the juvenile fish feed is 40-50%, and the adult fish feed The fish feed needs to meet the daily intake of 1.2-1.3g of protein per 100g of fish weight in adult fish.

[0021] The feed for juvenile fish includes the following components by weight: 41-49% steam-dried fish meal, 11-15% high-gluten flour, 2-5% corn, 10-24% peeled soybean meal, 5% pork powder -10%, soybean oil 2-5%, peanut meal 2-4%, minerals 1-2%, calcium dihydrogen phosphate 1-2%, choline chloride 0.4%, methionine hydroxyl analog calcium salt 0.1-0.3% , enzymatic fish paste 1-5%, multidimensional 0.1-0.35%, ...

Abstract

The invention belongs to the technical field of aquatic compound feed, and particularly relates to a composition of sinking expanded compound feeds for leiocassis longirostris and a preparation methodthereof. According to the invention, differentiated adjustment of protein contents is carried out on a juvenile fish-stage feed, a young fish-stage and an adult fish-stage feed, and the proportions of the components of the feeds are reasonably adjusted, so that the effect that the three feeds meet the nutritional requirements of leiocassis longirostris in three stages in a targeted manner is achieved. The compositon has the advantages that: the three feeds are scientific and reasonable in respective material ratio, the nutritional requirements of the leiocassis longirostris in three differentstages can be met in a targeted mode, the three feeds are good in palatability, high in conversion rate and good in water stability, and the feed preparation process is reasonable and effective.

Description

technical field [0001] The invention belongs to the technical field of aquatic product compound feeds, and in particular relates to a combination of long-snout sinking puffed compound feeds and a preparation method thereof. Background technique [0002] Commonly known as Jiangtuan, catfish, squid fish or fat lump, long-snout squid belongs to the genus of ray-finned fishes, Siluriformes, and is an important economic fish in my country. In recent years, the artificial breeding of long-snout catfish has risen rapidly in Hubei, Sichuan, Chongqing, Guangdong, Anhui and other places in my country, and the demand for artificial compound feed is also increasing. Among them, the palatability, survival rate and feed conversion rate of feed and other indicators are important indicators for evaluating the compound feed of long-snout catfish, but in the actual breeding, there is still a lack of a staged feed that can meet the feed needs of long-snout catfish in the three stages of juvenil...
