Embodiment 1

[0014] When preparing the high-efficiency compound animal protein of the present invention, earlier each component is ground into fine powder, crosses the sieve of 80 objects; Take by weighing chicken powder 14.62kg, puffed blood powder 4.5kg, puffed feather powder 3.38kg; Make chicken powder, puffed blood powder and The ratio of puffed feather meal is 13:4:3. The compound animal protein was prepared by mixing step by step, and then the compound animal protein was used as raw material to replace the fish meal in the Penaeus vannamei feed. The replacement rate was 90%, and then the experimental feed of high-efficiency compound animal protein was prepared. The experimental feed was divided into 1mm and 1.5mm. particle size. The vannamei feed used may be a commercially available product, such as No. 0 and No. 2 feeds for grass shrimp in Guangdong.

[0015] Experiments in Zhanjiang, Guangdong show that the above-mentioned high-efficiency compound animal protein was used as a raw ...

Embodiment 2

[0017] When preparing the high-efficiency compound animal protein of the present invention, earlier each component is ground into fine powder, crosses 80 mesh screens; Dicalcium phosphate 1.85kg, puffed feather powder 3.38kg, puffed blood powder 4.5kg, chicken powder 14.62kg; Gradually Compound animal protein was prepared by mixing, and then the compound animal protein was used as a raw material to replace 70% of the fish meal in the diet of Penaeus vannamei to prepare an experimental feed of high-efficiency compound animal protein. The experimental feed was divided into two particle sizes of 1mm and 1.5mm.

[0018] Due to the addition of calcium dihydrogen phosphate in the compound animal protein, Penaeus vannamei can have a better digestion and absorption rate for the components of the compound protein. In the compound protein group of calcium dihydrogen, the residual rate of chicken meal, puffed blood meal, and puffed feather meal in the feces of the cultured prawns was abou...

Abstract

The invention relates to a composite animal protein which is composed of chicken meal, expanded blood meal and expanded feather meal. The composite animal protein also contains calcium dihydrogen phosphate. The high-efficiency composite animal protein is used for the preparation of feeds for Litopenaeus vannamei. According to the invention, the high-efficiency composite animal protein can effectively replace a fish meal protein in the feeds for Litopenaeus vannamei; the survival, growth, food intake and feed efficiency of Litopenaeus vannamei and the physical and chemical composition of Litopenaeus vannamei are not affected; the purposes of lowering the feed price and saving the culture cost are achieved; and ocean resources can be protected.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a compound animal protein and its preparation and application, in particular to a high-efficiency compound animal protein for Litopenaeus vannamei feed. Background technique [0002] Litopenaeus vannamei, commonly known as Penaeus vannamei, is one of the three largest shrimp species in the world with the highest aquaculture output. It has strong resistance to water environments, fast growth, large meat content, delicious meat, and rich nutrition. It has many characteristics and is widely cultivated in my country, mainly using granular feed for breeding activities. However, large-scale intensive farming consumes more and more pellet feed, especially fishmeal, which leads to high feed prices, increased farming costs, and is not conducive to the protection of marine resources. Therefore, the development of new protein sources has become an urgent problem to be solved in the...
