Problems solved by technology

At present, the quantity and quality of feed raw materials in my country cannot meet the needs of the rapid development of my country's feed industry. How to add feed additives to improve feed efficiency, reduce feed coefficient, and improve the quality and survival rate of California perch has become a key issue in the freshwater aquaculture industry. important question
At present, there is still no report about similar feed additives

Embodiment 1

[0029] A California perch feed added with phyllophyll is prepared from the following raw materials in mass percentage:

[0030] fish meal 40％ fishmeal protein substitute 34.5％ standard flour 17.5％ fish oil 2％ Vitamin Mineral Salt Mix 3％ Calcium Dihydrogen Phosphate 2％ Choline chloride 0.5％ Phyllostachys powder 0.5％

[0031] In the feed added with the phyllophyllum additive, the mass fraction of crude protein is 47.28%, and the mass fraction of crude fat is 10.84%.

[0032] Note: The crude protein and crude fat of experimental samples were determined according to the standard method (AOAC, 1984). The crude protein content was determined by the Kjeldahl method (total nitrogen × 6.25); the crude fat content was determined by the Soxhlet extraction method (with diethyl ether as the extract).

[0033] The feed was prepared according to the formula shown in the table above, and California perch with an initial body weight of 3...

Embodiment 2

[0042] A California perch feed added with phyllophyll is prepared from the following raw materials in mass percentage:

[0043] fish meal 40％ fishmeal protein substitute 34.5％ standard flour 17％ fish oil 2％ Vitamin Mineral Salt Mix 3％ Calcium Dihydrogen Phosphate 2％ Choline chloride 0.5％ Phyllostachys powder 1％

[0044] In the feed added with the phyllophyllum additive, the mass fraction of crude protein is 47.23%, and the mass fraction of crude fat is 10.40%.

[0045] The feed was prepared according to the formula shown in the table above, and California perch with an initial body weight of 3.67±0.04 g were fed for 56 days. The specific growth rate of California perch fed on the feed of this embodiment was 4.58±0.05, the fullness was 2.10±0.05, the survival rate was 95.56%, the feed efficiency was 1.40±0.05, the viscera-body ratio was 6.51%, and the liver-body ratio was 2.27%. The fish body fat content is 23.73%, the bo...

Abstract

The invention discloses application of phyllanthus urinaria in aquatic feed and weever feed. The phyllanthus urinariais used in the form of powder. The weever feed contains 0.5 to 1.0% (W / W) of the powder of the phyllanthus urinaria and further contains fish meal, fish meal protein substitute, flour, fish oil, the mixture of vitamin and mineral salt, monocalcium phosphate, and choline chloride. The phyllanthus urinaria is added to the feed, because the hepatosomatic index increases and the improvement of liver function is conducive to digestion and improving immunity, the feed efficiency is improved, the growth rate and the survival rate are increased, the cost is lowered, the economic benefit is increased, and meanwhile safety of aquatic food is ensured; and the feeding effect is also significantly better than that of existing compound feed.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to the application of phyllophylla in aquatic feed and perch feed. Background technique [0002] Fish is rich in nutritional value. In addition to being an important source of protein, fish is usually rich in essential minerals, vitamins and unsaturated fatty acids. [0003] California perch is a type of carnivorous freshwater fish. It is currently bred in a large amount in Guangdong, and most of them are fed with chilled fish. Due to the scarcity of chilled fish resources, the cultivation of California perch is limited to a certain extent. Therefore, it is the general trend to vigorously develop artificial compound feed to breed California perch. [0004] Feed cost is the main component of animal breeding cost. At present, the quantity and quality of feed raw materials in my country cannot meet the needs of the rapid development of my country's feed industry. How to add f...
