Embodiment 1

[0036] A compound feed for grass carp juveniles is prepared from the following raw materials in mass percentage:

[0037] fish meal 8％ fishmeal protein substitute 52％ standard flour 28.5％ Cellulose 4％ fish oil 2％ peanut oil 2％ Vitamin Mineral Salt Mix 1％ Calcium Dihydrogen Phosphate 1％ Choline chloride 0.5％ Allicin 1％

[0038] In the compound feed for juvenile grass carp, the mass fraction of crude protein is 35.62%, and the mass fraction of crude fat is 9.81%.

[0039] 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).

[0040] Feeds were formulated according to the formula shown in the table above, and grass carp with an initial body weight ...

Embodiment 2

[0048] A compound feed for grass carp juveniles is prepared from the following raw materials in mass percentage:

[0049] fish meal 8％ fishmeal protein substitute 52％ standard flour 27.5％ Cellulose 4％ fish oil 2％ peanut oil 2％ Vitamin Mineral Salt Mix 1％ Calcium Dihydrogen Phosphate 1％ Choline chloride 0.5％ Allicin 2％

[0050] In the compound feed for juvenile grass carp, the mass fraction of crude protein is 35.94%, and the mass fraction of crude fat is 9.71%.

[0051] Feeds were formulated according to the formula shown in the table above, and grass carp with an initial body weight of 18.8±1.06 g were fed for 56 days. Grass carp that ingested the feed of this embodiment had a specific growth rate of 3.28±0.38, a fullness of 1.99±0.07, a feed efficiency of 1.22±0.33, a viscera-body ratio of 11.97%, and a liver-body ratio of 2.18%. The microbial community composition is shown in the attached figure.

Embodiment 3

[0053] A compound feed for grass carp juveniles is prepared from the following raw materials in mass percentage:

[0054] fish meal 8％ fishmeal protein substitute 52％ standard flour 26.5％ Cellulose 4％ fish oil 2％ peanut oil 2％ Vitamin Mineral Salt Mix 1％ Calcium Dihydrogen Phosphate 1％ Choline chloride 0.5％ Allicin 3％

[0055] In the compound feed for juvenile grass carp, the mass fraction of crude protein is 35.22%, and the mass fraction of crude fat is 9.73%.

[0056] Feeds were formulated according to the formula shown in the table above, and grass carp with an initial body weight of 20.6±1.04 g were fed for 56 days. The specific growth rate of grass carp eating the feed of this embodiment is 2.92±0.17, the fullness is 1.99±0.09, the feed efficiency is 1.01±0.12, the viscera-body ratio is 11.55%, and the liver-body ratio is 1.94%.

Abstract

The invention discloses a young grass carp compound feed capable of promoting growth and improving intestinal functions and a preparation method of the young grass carp compound feed. The compound feed for the young grass carp is prepared from fish meal, a fish meal protein substitute, standard flour, cellulose, fish oil, peanut oil, a vitamin mineral salt mixture, monocalcium phosphate, choline chloride and 1%-4% allicin, and the weight of the young grass carp is 15-25 grams. The young grass carp compound feed disclosed by the invention can improve villus length and muscle thickness of intestinal tracts, and improvement of the villus length and the muscle thickness is beneficial to digestion, so that the feed efficiency is improved, the growth rate is improved, the cost is reduced, the economic benefit is improved, meanwhile, the safety of aquatic food is further guaranteed. and the feeding effect is obviously better than that of an existing compound feed.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a compound feed for juvenile grass carp that promotes growth and improves intestinal function and a preparation method thereof. Background technique [0002] Fish is rich in protein, essential minerals, vitamins and unsaturated fatty acids, and is an important food source for humans. Worldwide, fish consumption is significant. [0003] Grass carp (Ctenopharyngodon idellus) is an important freshwater aquaculture fish in China. It has the advantages of rapid growth, rich nutrients, and low price. It is a fish species with both prosperous supply and demand in my country. [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 improve the feed formula to improve feed efficiency, reduce feed coefficient, and pro...
