Problems solved by technology

However, this fish is omnivorous and carnivorous. To ensure its normal growth, enough fishmeal protein must be added to the feed, which will inevitably lead to higher feed costs.
Therefore, the saving of feed cost is an important problem in the large-scale cultivation of yellow catfish. The current solution is mainly to improve the amino acid balance of the feed through the addition of crystal amino acids, which can improve the substitution effect to a certain extent, but the cost is high. This makes it difficult to reduce the cost of the whole feed

Embodiment 1

[0018] Example 1 (R1)

[0019] Peeled catfish juvenile feed included 9.8% soybean meal, 34% fish meal, 7.25% cotton meal, 7.85% rapeseed meal, 4.0% blood cell meal, 4.0% corn gluten meal, 20.0% flour, 4.0% salad Oil, 1.5% Mineral Salt Premix, 2.0% Monocalcium Phosphate, 0.39% Vitamin Premix, 0.11% Vitamin C, 0.1% Choline Chloride, 4.0% A-Starch, Guaranteed Yellow Catcher The protein content of fish juvenile fish feed is not less than 42% of the total weight. The method of cultivating yellow catfish is mainly to alternately feed juvenile fish feed with high proportion of animal protein and feed with low proportion of animal protein at intervals. In the whole process, the feed was first fed for 4 weeks, and then the feed was fed for 4 weeks, and the experiment lasted for 8 weeks.

[0020] Before the start of the experiment, the fish were starved for 24 hours, and the temporary fish were mixed, then randomly sampled and weighed, 30 fish were placed in each box, and 4 groups (8 ...

[0022] Example 2 (R2)

[0023] Peeled catfish juvenile diet includes 14.5% soybean meal, 25.5% fish meal, 7.25% cotton meal, 7.85% rapeseed meal, 4.0% blood cell meal, 4.0% corn gluten meal, 14.0% flour, 4.0% salad Oil, 1.5% Mineral Salt Premix, 2.0% Monocalcium Phosphate, 0.39% Vitamin Premix, 0.11% Vitamin C, 0.1% Choline Chloride, 4.0% A-Starch, Guaranteed Yellow Catcher The protein content of fish juvenile fish feed is not less than 42% of the total weight. The method of cultivating yellow catfish is mainly to alternately feed juvenile fish feed with high proportion of animal protein and feed with low proportion of animal protein at intervals. In the whole process, the feed in Example 1 was fed for 4 weeks first, and then the feed in Example 2 was fed for 4 weeks, and the experiment lasted for 8 weeks in total.

Embodiment 3

[0026] Example 3 (R3)

[0027] The feed for juvenile yellow catfish included 29.0% soybean meal, 17.0% fish meal, 7.25% cotton meal, 7.85% rapeseed meal, 4.0% blood cell meal, 4.0% corn gluten meal, 8.0% flour, and 4.0% salad Oil, 1.5% Mineral Salt Premix, 2.0% Monocalcium Phosphate, 0.39% Vitamin Premix, 0.11% Vitamin C, 0.1% Choline Chloride, 4.0% A-Starch, Guaranteed Yellow Catcher The protein content of fish juvenile fish feed is not less than 42% of the total weight. The method of cultivating yellow catfish is mainly to alternately feed juvenile fish feed with high proportion of animal protein and feed with low proportion of animal protein at intervals. The whole process was first fed with the feed in Example 1 for 4 weeks, and then fed with the feed in Example 3 for 4 weeks, and the experiment lasted for 8 weeks in total.

Abstract

The invention discloses a feed proportioning method and a cultivation method of juvenile yellow catfish. The proportioning method is characterized in that a juvenile yellow-head catfish feed mainly comprises 9.8-43.2wt% of vegetable protein, 34-8.8wt% of animal protein and the balance of an auxiliary feed. The cultivation method of the yellow-head catfish meat mainly comprises the step of: alternately feeding the juvenile fish by a juvenile fish feed with high-specific gravity animal protein and a juvenile fish feed with low-specific gravity animal protein at time intervals. The conventional feeding mode only uses a feed with single specification in the cultivation of the juvenile yellowcatfish. The invention makes use of the characteristic of the compensation growth of the yellow catfish, and the juvenile fish feed with the high-specific gravity animal protein and the juvenile fish feed with the low-specific gravity animal protein are alternately fed at time intervals, so that the feed efficiency can be improved, and the feed cost can be saved on the premise that the weight increment of the yellow catfish is not influenced.

Description

technical field [0001] The invention relates to a feed ratio for juvenile yellow catfish and a breeding method thereof, belonging to the technical field of aquatic animal breeding. Background technique [0002] Pelteobagrus fulvidraco Richardson is an important economic fish in freshwater aquaculture in my country. It has attracted the attention of the aquaculture industry for its short growth cycle, high population yield, high economic benefits, and wide temperature adaptability. In recent years, the market demand volume continued to grow rapidly. However, this fish is an omnivorous partial carnivorous fish. To ensure its normal growth, enough fishmeal protein must be added to the feed, which will inevitably lead to higher feed costs. Therefore, the cost saving of bait is an important problem in the large-scale cultivation of yellow catfish. The current solution is mainly to improve the amino acid balance of the feed through the addition of crystalline amino acids, which ca...
