Embodiment Construction

[0007] The invention has great significance for improving the feed utilization rate of the oval pomfret, expanding the selection range of feed raw materials for the oval pomfret, reducing feed costs, reducing environmental pollution, and promoting the healthy development of the oval pomfret breeding industry.

[0008] Take by weighing dimethyl-beta-thiotin 30kg, hypoxanthine nucleotide 25kg, sodium citrate 15kg, aspartic acid 15kg, glutamic acid 15kg, these five kinds of compositions are ground into fine powder (over 120 order), and then mix uniformly in a mixer (requiring coefficient of variation≤5%), which is the high-efficiency composite food attractant of the present invention. Addition amount of compound feed: 0.1%-0.2%.

[0009] From 2005 to 2007, the experiments in Hainan and Guangdong showed that in the full-cycle use of inshore cages and deep-water anti-wind and wave cages, the compound feed added with high-efficiency compound food attractant for pomfret ovata was hig...

Abstract

The invention relates to a compound attraction agent for golden pomfrets, which comprises five ingredients by weight percentages (W / W): 20 to 30 percent of dimethyl-beta-propionate thetin, 20 to 30 percent of hypoxanthine nucleotide, 10 to 20 percent of sodium citrate, 10 to 20 percent of aspartam aspartic acid and 10 to 20 percent of glutamic acid. The invention has the advantages that the compound attraction agent used as feed additive in golden pomfret feed is added by only 0.1 percent to 0.2 percent, the ingestion rate of the golden pomfrets is obviously improved so as to stimulate the growth, and residual feed is reduced so as to benefit the environmental protection; the consumption of fish meal in the feed can be greatly reduced so as to protect fishing resources and decrease the feed cost, and raw materials used in the compound attraction agent have stable resources, low cost and simple production technology.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound food attractant for oval pomfret. technical background [0002] Fish and shrimp food attractant is developed on the theoretical basis of fish and shrimp's sense of smell and taste combined with their feeding behavior. It refers to a class of substances that can attract fish and shrimp to food and stimulate their appetite to promote their food intake. The food attractant stimulates the sense of smell, taste and vision of fish and shrimp to gather around the feed, speed up food intake and increase feed intake. Fish and shrimp food attractant can improve the palatability of feed, increase food intake and feed utilization rate, and also reduce water pollution, thereby reducing fish morbidity and mortality, and increasing economic benefits. [0003] Oval pomfret (Trachinotus ovatus), commonly known as golden pomfret, is a rare edible fish with tender meat and delicious taste. It is a mar...
