preparation example Construction

[0024] A method for preparing a biological feed for bighead carp, the steps comprising:

[0025] Take the mixture first: fish meal 35~50kg, rapeseed meal 440~485kg, rice flour 150~200kg, soybean meal 40±10kg, soybean lecithin oil 10±1kg, rice bran 250±25kg, compound vitamin 1±0.1kg and compound mineral salt 10±1kg;

[0026] Then mix the mixture with 2.5±0.25kg of compound enzyme, enzymatically hydrolyze for 8 hours, then inoculate 2.5±0.25kg of compound bacteria, and ferment for 28±2 hours at a temperature of 35±3.5°C to prepare the bighead carp biological feed;

[0027] The total mass of the mixture, composite enzyme and composite bacteria is 1000kg;

[0028] For the multivitamins: the types and mass percentages contained in each 1kg are: VA≥10 million IU / kg, VD≥2 million IU / kg, VE≥60000mg / kg, VK 3 ≥8000mg / kg, VB 1 ≥8000mg / kg, VB 2 ≥8000mg / kg, VB 6 ≥20000mg / kg, niacin≥25000mg / kg, pantothenic acid≥20000mg / kg, folic acid≥5000mg / kg, VB 12 ≥100mg / kg, VC≥200000mg / kg, biotin≥2...

Embodiment 1

[0040]Production of bighead carp biological feed, specific formula: fish meal 50kg, soybean meal 40kg, rapeseed meal 484kg, soybean lecithin oil 10kg, rice flour 150kg, rice bran 250kg, compound vitamin 1kg, compound mineral salt 10kg, compound bacterial enzyme 5kg, total 1000kg. During production, the components of each raw material should meet their respective quality requirements, and the error of component measurement accuracy during preparation is less than ±0.5%. Take each component as raw material and stir evenly, mix with 2.5kg of compound enzyme, enzymatically hydrolyze for 8 hours, then inoculate 2.5kg of compound strain, and ferment for 28 hours at a temperature of 35°C to prepare bighead carp biological feed. The product is generally made into Powder and granule mixture, no peculiar smell, no agglomeration, mildew and moth, no foreign matter. Moisture should not be higher than 12.5%.

Abstract

The invention discloses a preparation method of a bighead carp biologic feed. The method comprises the following steps of: mixing fish meal, rapeseed meal and the like and complex enzyme, and inoculating compound strains to prepare the feed. A method for feeding the feed which is obtained by the method to bighead carp by using a mesh bag comprises the following steps of: 1) preparing the bighead carp feeding mesh bag, and filling the feed into the mesh bag; 2) stocking bighead carp fry in each acre of a fish pond; 3) fixing an appropriate mesh bag in water according to the size of the cultivation pond mouth; and 4) feeding according to time. The feed has the advantages that: the feed is rich in various nutrient substances which are required by bighead carp, improves the nutrient absorption rate, obviously improves immunity and premonition, automatically adjusts water quality, and is high in economic benefit and pollution-free. The feed method meets the feeding habit of touch feeding of the bighead carp, greatly increases the growth speed of the bighead carp, and can reduce the feed loss to the maximum extent, improve the feed efficiency, reduce the cultivation feed cost and is suitable for centralization cultivation of the bighead carp.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a preparation method of biological feed for bighead carp and a net bag feeding method thereof. Specifically, the biological feed for bighead carp is prepared by using microbial fermentation technology and enzyme engineering technology, and a special net bag is designed and manufactured to feed the bighead carp biological feed. Background technique [0002] Before the new century, the prices of bighead carp and silver carp were almost the same, and they were both low-priced bulk fish. Fishermen were not enthusiastic about breeding them, and they simply mixed them together, which was better than nothing. In recent years, the price trend of bighead carp is obviously different from other bulk freshwater fish such as silver carp, grass carp, carp, crucian carp, and bream, and the average price has risen almost every year. The production enthusiasm of the majority of farmers was obviously mobi...
