Leiocassis longirostris feed capable of increasing fat utilization rate

Abstract

The invention discloses a leiocassis longirostris feed capable of increasing the fat utilization rate. The leiocassis longirostris feed is prepared from the following components in parts by weight: 50-78 parts of a plant powder component, 21-38 parts of an animal protein powder component, 6-14 parts of a grease component, 2.71-4.53 parts of a nutrient component, 0.02-0.05 part of bile acid, 0.01-0.02 part of L-carnitine, 0.1-0.3 part of methionine, 0.1-0.3 part of choline chloride, 0.01-0.02 part of an antioxidant namely acridon and 0.1-0.3 part of crystal lysine. According to the leiocassis longirostris feed capable of increasing the fat utilization rate disclosed by the invention, the quantity of saturated fatty acids is reduced, and the variety quantity of high-quality grease including soybean oil, fish oil, phosphatide oil and the like is added, so that polyunsaturated fatty acids required for rapid growth of leiocassis longirostris are provided; in accordance with the problem of digestive disorder of fish bodies after the addition quantity of fat is increased, an emulsifying agent and the bile acid are added, so that the emulsifying function is strengthened, and the digestive absorption of the fat is promoted; and in accordance with the decomposition energy supply of the fatty acids, micronutrient namely the L-carnitine for promoting fat metabolism energy supply is added.

Description

technical field [0001] The invention belongs to the technical field of catfish feed, and in particular relates to a catfish feed that improves fat utilization. Background technique [0002] Catfish generally refers to long-snouted catfish, which is a fish of the family Ospreyidae and the genus Catfish. Body elongated, thick and short in front, flattened in back. The head is slightly larger, and the back is raised, not covered by the membrane; the upper occipital spine is rough and exposed. The snout is pointed and prominent, tapered. Mouth inferior, arc-shaped. Lip hypertrophy. The upper jaw protrudes beyond the lower jaw. The eyes are small, located on the upper side, and the eye margins are not free, and are covered with a film. Widely spaced, raised eyes. The whiskers are located at the front edge of the posterior nostril, and the rear end reaches the edge of the eye. Gill openings large. Gill cover membrane not connected to gill canyons. Gill rakers small. Bod...

Problems solved by technology

[0006] 3. The latest research shows that if the amount of saturated fatty acid in the feed reaches a certain level, if it is added again, it will have a very negative impact on growth performance

[0007] 4. The high metabolic rate under the condition of high-protein and high-fat diet leads to the accumulation of a large number of free radicals in the body. On the one hand, it leads to the exhaustion of antioxidant substances in the body, and on the other hand, it leads to damage to internal organs, especially the liver. This is constantly pursuing high-speed The formula mode of growth is particularly prominent, which leads to low anti-stress ability of the fish body and difficulty in transportation out of the pond. As long as there is energy metabolism, free radicals will be generated, and the body needs to consume some energy to eliminate free radicals
