Embodiment 2

[0033] This example provides a long-snout catfish feed and its preparation method. The only difference from Example 1 is that the mixed powder of agricultural and forestry by-products is adjusted to 29 parts, the soybean meal is adjusted to 21 parts, and the corn flour is adjusted to 33 parts; the remaining steps and parameters are all same.

experiment example

[0041] The long-snout catfish feed provided by this embodiment 1-2 and comparative example 1-3 was used to carry out a two-month comparative breeding test. The experiment was carried out in cages, each of the 5 groups used 3 cages, and 10 long-snout catfish with an initial average weight of 54.5 g were placed in each cage. During the experiment, they were fed twice a day (8.30 am and 4.30 pm). Weighed after the experiment, and the growth results are shown in Table 1.

[0042] Table 1

[0043]

[0044] After the two-month comparative breeding experiment, in this case, 3 surviving long-snout catfish were randomly selected for dissection in the 5 groups, and the average liver weight (g) was weighed. The test results are shown in Table 2.

Abstract

The invention discloses a leiocassis longirostris feed and a preparation method thereof. The leiocassis longirostris feed is prepared from the following raw materials in parts by mass: 29-37 parts of mixed powder of agricultural and forestry byproducts, 21-26 parts of soybean meal, 33-36 parts of corn flour, 3-6 parts of vegetable oil, 0.5-2 parts of a vitamin additive, 0.5-5 parts of a mineral additive and 0.2-3 parts of a Chinese herbal medicine additive, wherein the mixed powder of the agricultural and forestry byproducts is prepared from silkworm chrysalis, snail meat and earthworms according to the mass ratio of (4-10): (2-5): 1; the Chinese herbal medicine additive comprises the following components in parts by mass: 15-25 parts of boxthorn leaves, 10-15 parts of honeysuckle flowers, 15-25 parts of lotus leaves and 3-7 parts of astragalus stems and leaves. The invention can effectively solve the problems of high cost, easy formation of fatty liver and other fatty diseases and the like in the existing leiocassis longirostris feed.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a long-snout catfish feed and a preparation method thereof. Background technique [0002] Commonly known as Jiang Tuan and Fatuo, Long-snout Scorpion belongs to Siluriformes, Osmanthidae, and Scorpion genus. Long-snout Scorpion is tender, delicious, and has no spines. It is known as the top-grade freshwater edible fish. Its swim bladder is thick and dried into fish maw. It is also a rare delicacy, and the "bijia fish maw" produced in Shishou, Hubei Province has always enjoyed a high reputation. [0003] In the whole process of fish farming production, the input of bait accounts for more than half of the cost of farming. At present, there are mainly the following problems in the diet of long-snout catfish: 1) fishmeal is used as the main nutrient in the long-snout catfish feed, which greatly increases the production cost of long-snout catfish breeding; 2) excessive feed protein and ...
