preparation example Construction

[0030] Simultaneously, the invention discloses a preparation method of a special feed for the multi-scale white turtle broodstock, comprising the following steps:

[0031] Step 1, pulverizing and sieving fish meal, soybean meal, rapeseed meal, cottonseed meal, flour, rice bran, cellulose, bentonite, calcium dihydrogen phosphate and fish premix respectively;

[0032] Step 2, take crushed and sieved fish meal, soybean meal, rapeseed meal, cottonseed meal, flour, rice bran, cellulose, bentonite, calcium dihydrogen phosphate, fish premix and soybean oil according to any one of the above claims 1 to 4 The proportioning of the special feed of the multi-scale white turtle broodstock is mixed evenly;

[0033] Step 3, adding the uniformly mixed raw materials to the pellet feed machine gradually and in small quantities for pelleting, and collecting the prepared pellet feed;

[0034] Step 4, air-dry the prepared pellet feed, and freeze it for storage.

[0035] Specifically, in the abov...

Embodiment 1

[0039] First, fish meal, soybean meal, rapeseed meal, cottonseed meal, flour, rice bran, cellulose, bentonite, calcium dihydrogen phosphate and fish premix are respectively pulverized and sieved; in this embodiment, a 40-mesh sieve is passed;

[0040] Then, take 285 grams of crushed and sieved fish meal, 140 grams of soybean meal, 14 grams of rapeseed meal, 230 grams of cottonseed meal, 149 grams of flour, 85 grams of rice bran, 10 grams of cellulose, 10 grams of bentonite, 20 grams of calcium dihydrogen phosphate, Mix 10 grams of fish premix and 47 grams of soybean oil;

[0041] Secondly, the above-mentioned homogeneously mixed raw materials are gradually added to the pellet feed machine in a small amount to make pellets with a diameter of 1.5 mm, and the prepared pellet feed is collected;

[0042] Finally, the prepared granular feed is air-dried and stored in freezer for future use. In this example, the prepared granular feed was air-dried for 48 hours and stored in a refri...

Embodiment 2

[0046] First, fish meal, soybean meal, rapeseed meal, cottonseed meal, flour, rice bran, cellulose, bentonite, calcium dihydrogen phosphate and fish premix are respectively pulverized and sieved; in this embodiment, a 40-mesh sieve is passed;

[0047] Then, take 285 grams of crushed and sieved fish meal, 140 grams of soybean meal, 14 grams of rapeseed meal, 247 grams of cottonseed meal, 117 grams of flour, 78 grams of rice bran, 10 grams of cellulose, 10 grams of bentonite, 20 grams of calcium dihydrogen phosphate, Mix 10 grams of fish premix and 69 grams of soybean oil;

[0048] Secondly, the above-mentioned homogeneously mixed raw materials are gradually added to the pellet feed machine in a small amount to make pellets with a diameter of 1.5 mm, and the prepared pellet feed is collected;

[0049] Finally, the prepared pellet feed was air-dried for 48 hours and stored in the refrigerator (-20°C) for later use.

[0050] Among them, the fish premix per kilogram includes: VA 6...

Abstract

The invention relates to a special feed for parent fishes of onychostoma macrolepis and a preparation method thereof. The feed is characterized by comprising, by weight, 28.5% of fish meal, 14% of soybean meal, 1.4% of rapeseed meal, 23%-24.7% of cottonseed meal, 11.7%-14.9% of flour, 7.8%-8.5% of rice bran, 1%-8.5% of cellulose, 4.7%-6.9% of soybean oil, 1% of bentonite, 2% of calcium dihydrogenphosphate and 1% of a fish premix, wherein 1 kg of the feed comprises 90-110 g of lipid. By adopting the feed, the problem is solved that there has been no special feed for the parent fishes of onychostoma macrolepis for a long time. Meanwhile, the feed has important significance in promoting the reproduction efficiency and scale of the parent fishes of onychostoma macrolepis and large-scale breeding of onychostoma macrolepis, boosting the development of the industry, increasing the economic income of fishermen to make the fishermen get rid of poverty and become rich, and facilitating the conservation of fishery germplasm resources and the recovery of species diversity in Qinba mountain areas.

Description

technical field [0001] The invention belongs to the technical field of aquaculture feed, and in particular relates to a special feed for multi-scale white turtle broodstock and a preparation method thereof. Background technique [0002] The multi-scaled white turtle is a unique economic fish in the Qinling Mountains. The fish is rich in nutrition and delicious, and has a good development and utilization prospect. However, due to overfishing and the destruction of the ecological environment, the wild population of this fish has declined sharply, and its resources have plummeted. Many provinces such as Shaanxi and Gansu have listed it as a provincial endangered animal. [0003] Artificial multiplication is an effective way to protect and utilize this important aquatic resource. At the same time, in view of the sharp decline in the wild population of this fish, artificial multiplication and release is also a means of protection for wild germplasm resources of economic fish, and...
