Embodiment 1

[0047] A low-protein and high-fat puffer puffer compound feed is prepared from the following raw materials in mass percentage:

[0048]

[0049]

[0050] In the environment-friendly and high-efficiency fugu obscura compound feed, the mass fraction of crude protein is 42%, and the mass fraction of crude fat is 9%.

[0051] 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).

[0052] The feed was formulated according to the formula shown in the above table, and puffer fish with an initial body weight of 12.75±0.20 g were fed for 56 days. The weight gain rate of pufferfish feeding on the feed of this embodiment is 195.25 ± 13.13%, the survival rate is 92.5 ± 1.4%, the feed factor is 1.80 ± 0.10, the plumpness...

Embodiment 2

[0062] A low-protein and high-fat puffer puffer compound feed is prepared from the following raw materials in mass percentage:

[0063]

[0064]

[0065] In the environment-friendly and high-efficiency fugu obscurus compound feed, the mass fraction of crude protein is 42%, and the mass fraction of crude fat is 12%.

[0066] The feed was formulated according to the formula shown in the above table, and puffer fish with an initial body weight of 12.75±0.20 g were fed for 56 days. The weight gain rate of the pufferfish feeding on the feed of this embodiment is 208.99 ± 6.54%, the survival rate is 93.75 ± 1.25%, the feed coefficient is 1.67 ± 0.08, the plumpness is 2.54 ± 0.04%, the viscera ratio is 16.29 ± 0.24%, the liver The body ratio is 12.81±0.18%, the body fat content of the whole fish is 29.17±0.68%, and the red blood cell count is 173.78±2.86×10 7 / ml.

Embodiment 3

[0068] A low-protein and high-fat puffer puffer compound feed is prepared from the following raw materials in mass percentage:

[0069]

[0070]

[0071] In the environment-friendly and high-efficiency fugu obscurus compound feed, the mass fraction of crude protein is 42%, and the mass fraction of crude fat is 15%.

[0072] The feed was formulated according to the formula shown in the above table, and puffer fish with an initial body weight of 12.75±0.20 g were fed for 56 days. The weight gain rate of the pufferfish fed on the feed of this embodiment was 179.16 ± 7.22%, the survival rate was 98.75 ± 1.25%, the feed factor was 1.74 ± 0.08, the plumpness was 2.60 ± 0.07%, the viscera ratio was 16.34 ± 0.59%, the liver The body ratio is 13.25±0.54%, the body fat content of the whole fish is 27.84±0.65%, and the red blood cell count is 200.89±4.32×10 7 / ml.

Abstract

The invention discloses a low-protein high-fat compound feed for takifugu obscures as well as a preparation method and application of the feed. The feed is prepared from fish meal, bean pulp, peanut bran, standard flour, fish oil, bean oil, rapeseed oil, yeast powder, choline chloride, vitamin C phosphate, calcium dihydrogen phosphate, carboxymethylcellulose, a mineral salt mixture, a vitamin mixture and a phagostimulant; by weight percent, the feed comprises 38%-42% of crude protein and 8%-18% of crude fat. The compound feed is low in fish meal content, low in protein content, high in fat content and high in feed conversion rate, the feed cost is remarkably reduced, and the culture benefit is increased; the granulated feed for raising takifugu obscures is convenient to apply, time and labor are saved, the feed waste is reduced, and good water quality is easily kept; the effect of raising takifugu obscures by the low-protein high-fat compound feed is remarkably superior to that of an existing compound feed.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a fish feed, in particular to a low-protein, high-fat compound feed for puffer pufferfish and its application. Background technique [0002] The cost of feed (especially protein raw materials) is the main component of animal breeding costs. At present, the quantity and quality of my country's feed raw materials cannot meet the needs of the rapid development of my country's feed industry, especially high-quality protein raw materials, such as 70% of fish meal depends on imports. [0003] The shortage of fishmeal is a global problem, but for a country like ours with a large population and large animal breeding, the challenge is even more severe. According to the statistics of the International Fishmeal and Fish Oil Organization (IFFO), the total output of fishmeal in the world between 1976 and 2007 was between 5 million and 7 million tons. my country's fish meal production ...
