Embodiment 1

[0014] 1. Breeding and management: choose healthy raw fish with an average weight of 83.20g, design 3 treatments (the addition ratio of black soldier fly larvae powder is respectively mass fraction 0, 3%, 5%, marked as control group, test group 1 and Test group 2, each group of feed (such as nitrogen and other energy), the feed formula is shown in Table 1, and after mixing uniformly, it is made as extruded feed, and each process is established in 3 parallels, with 9 net cages in total.

[0015] 1.5m x 1.5m x 2.0m, 20 raw fish were placed in each cage, fed with 4%-5% of body weight every day, twice a day. The breeding cycle is 71d. During the breeding period, the water temperature is 18.0-32.2°C, nitrite <0.005mg / L, and ammonia nitrogen <0.1mg / L.

[0016] The vitamin premix, based on the total mass fraction of 100%, consists of the following components: vitamin B 2 0.8%, Niacin 0.35%, Pantothenic Acid 0.3%, Vitamin B 12 0.003%, Biotin 0.007%, Vitamin C 5%, Vitamin E 1.6%, ...

Embodiment 2

[0032] The raw fish compound feed of the present invention comprises 20 parts by mass of fish meal, 20 parts of soybean meal, 3 parts of peanut meal, 3 parts of fermented soybean meal, 1 part of black soldier fly larva powder, 22 parts of high-gluten flour, 1 part of soybean lecithin, 2 parts of fish oil, 0.5 part of calcium dihydrogen phosphate, 0.1 part of vitamin premix, 0.1 part of mineral premix, 0.3 part of choline chloride, 0.1 part of vitamin C phosphate (35%), 0.1 part of L-lysine parts, L-methionine (envelope 50%) 0.1 parts. Mix evenly and make it as extruded feed.

[0033] Carry out experiment according to the experiment of embodiment 1, result finds, raw fish compound feed of the present invention can improve raw fish muscle quality, reduce serum cholesterol level, promote the compound feed of growth, also possess the same palatability and palatability as squid cream group simultaneously sex.

Embodiment 3

[0035] The raw fish compound feed of the present invention comprises 35 parts of fish meal, 35 parts of soybean meal, 10 parts of peanut meal, 10 parts of fermented soybean meal, 6 parts of black soldier fly larva powder, 28 parts of high-gluten flour, 3 parts of soybean lecithin, 4 parts of fish oil, Calcium dihydrogen phosphate 1.5 parts, vitamin premix 0.3 parts, mineral premix 1.0 parts, choline chloride 0.7 parts, vitamin C phosphate (35%) 0.3 parts, L-lysine 1.0 parts, L- Methionine (envelope 50%) 0.3 parts. Mix evenly and make it as extruded feed.

[0036] Carry out experiment according to the experiment of embodiment 1, result finds, raw fish compound feed of the present invention can improve raw fish muscle quality, reduce serum cholesterol level, promote the compound feed of growth, also possess the same palatability and palatability as squid cream group simultaneously sex.

Abstract

The invention discloses a Channa argus formula feed, which comprises Hermetia illucens L larva powder and other ingredients. According to the present invention, the squid paste is replaced by the Hermetia illucens L larva powder in the Channa argus formula feed, such that the food intake and the palatability (the Hermetia illucens L larva powder has advantages of attracting effect on Channa argus,feed palatability improving and feed utilization improving) cannot be affected, the health of Channa argus can be improved, and the growth of Channa argus can be promoted; and the Hermetia illucens Llarva powder has characteristics of controlled quality and less deterioration, and has the low cost compared to the squid paste, such that the Hermetia illucens L larva powder is expected to be widely used to replace the squid paste in the Channa argus formula feed.

Description

Technical field: [0001] The invention belongs to the field of fish feed, in particular to a raw fish compound feed capable of improving health and promoting growth. Background technique: [0002] Raw fish is also called black fish, which is a common name for snakehead fish such as snakeheads and snakeheads. At present, the main cultured species are snakeheads, snakeheads and their hybrids. It belongs to the distant hybrid offspring of snakehead and spotted snakehead, and has obvious distant heterosis, such as good meat quality, fast growth, strong disease resistance, large individual, less disease, and transportation resistance. Since the successful breeding of raw fish fry, it has been promoted on a large scale. At present, the breeding area of ​​raw fish in Guangdong Province alone is 68,000 mu, and it continues to extend to Jiangsu, Zhejiang, Hunan, Hubei and other inland provinces. It is a major special freshwater aquaculture species. At present, the national raw fish a...
