Embodiment 1

[0012] The formula is as follows:

[0013] 10 parts of tea powder, 10 parts of shrimp bran, 30 parts of soybean meal, 30 parts of bran, 15 parts of corn, 2 parts of additives, 3 parts of neem leaves.

[0014] Test: Select 1000 Penaeus vannamei with similar body length and weight, divide them into two groups, control group and test group, each group has 250 fish, 2 repetitions, and the test period is 60 days. The control group was the feed without tea powder, and the test group was the feed with tea powder.

[0015] Actual effect: Under the same growth environment conditions, the weight of the test group increased by 8%, the feed coefficient decreased by 15%, and the mortality rate decreased by 10% compared with the control group.

[0016] Add alfalfa meal of the present invention and feed the actual use situation of freshwater fish feed as follows:

[0017] In a shrimp pond in Xiqing District, Tianjin, the biological agent described in the embodiment was fed, and the feeding...

Embodiment 2

[0019] The opening biological preparation of vannamei shrimp seedlings is characterized in that the formula composition of the feed is as follows: 15 parts of shrimp bran, 25 parts of soybean meal, 25 parts of bran, 8 parts of corn, 2 parts of additives, 1 part of neem leaf; The cake is obtained through dehydration, drying, rolling and crushing.

Embodiment 3

[0021] The opening biological preparation of vannamei shrimp seedlings is characterized in that the formula of the feed is composed as follows: 15 parts of shrimp bran, 30 parts of soybean meal, 40 parts of bran, 20 parts of corn, 2 parts of additives, 3 parts of neem leaves; The cake is obtained through dehydration, drying, rolling and crushing.

Abstract

The invention discloses a biological agent for feeding vannamei shrimp seeds. The biological agent comprises the following components: 10-15 parts of tea dreg powder, 10-15 parts of shrimp meal, 25-30 parts of bean pulp, 25-40 parts of wheat bran, 8-20 parts of corn, 0.5-2 parts of an additive and 1-3 parts of melia azedarach leaves, wherein the tea dreg powder is prepared by soaking tea seed cake in water, drying, grinding and crushing. By adopting the biological agent disclosed by the invention, the growth speed of vannamei shrimp seeds can be increased by more than 8%, the food coefficient is reduced by more than 15%, the product quality is greatly improved, the immunocompetence of the vannamei shrimp seeds is improved, the stress resistance is improved, particularly when the water temperature is too high or too low and the vannamei shrimp seeds are transported for a long distance, the aquatic livestock death rate caused by insufficient oxygen and physical decline is reduced, and the death rate is reduced by more than 10%, so that the biological agent for feeding the vannamei shrimp seeds is safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of Penaeus vannamei feeding, and relates to a feed for shrimps in a pond, more specifically a biological preparation for feeding Penaeus vannamei seedlings and a preparation method thereof. Background technique [0002] At present, the conventional bait for feeding Penaeus vannamei has the problems of single species, low protein content, and low disease resistance of shrimp after eating.
