Abstract

A composite attraction agent for huchen relates to a composite attraction agent, which solves the problems of bad palatability and low feed intake of the existing feed for huchen. Calculated by mass percentages, the composite attraction agent for huchen is mixed by 20 to 30 percent of dimethyl-Beta-DMPT, 20 to 30 percent of taurine, 10 to 15 percent of glutamic acid, 10 to 15 percent of alanine, 10 to 15 percent of glycin as well as 10 to 15 percent of Sodium Inosinate. The composite attraction agent for huchen obtained by the invention improves the palatability of the feed and increases the feed intake of the huchen.

Example Embodiment

[0008] Specific embodiment one: In this embodiment, the composite phagostimulant for jerome salmon is composed of 20%-30% dimethyl-β-propionate thiamine, 20%-30% taurine, and 10%- 15% glutamic acid, 10%-15% alanine, 10%-15% glycine and 10%-15% sodium inosinine are mixed.
[0009] The compound food attractant for Zerro salmon is mixed according to the above-mentioned mass percentage, and it is fully mixed with a mixer until the coefficient of variation is less than 5%.
[0010] The compound feed attractant for jerome salmon of this embodiment is added in a feed amount of 0.1% to 0.5%.

Example Embodiment

[0011] Specific embodiment two: this embodiment is different from the specific embodiment one in that the compound attractant for jerome salmon is composed of 25% dimethyl-β-propionate Thiatin, 25% taurine, 12% by mass. % Glutamic acid, 12% alanine, 12% glycine and 14% sodium inosinine are mixed. Others are the same as the first embodiment.
[0012] The three-component feed was used for comparison to compare the inventive effects of the compound phagostimulant for jerome salmon of this embodiment.

[0016] Vitamins
[0017] Note: Vitamins include: V C 1000mg/kg, V E 60mg/kg, V K 5mg/kg, V A 15000IU/kg, V D3 3000IU/kg, V B1 15mg/kg, V B2 30mg/kg, V B6 15mg/kg, V B12 0.5mg/kg, niacin 175mg/kg, folic acid 5mg/kg, inositol 1000mg/kg, biotin 2.5mg/kg, calcium pantothenate 50mg/kg; trace elements include: iron 25mg/kg, copper 3mg/kg, manganese 15mg/kg, iodine 0.6mg/kg.
[0018] Feed 1 is a high fishmeal control group (fishmeal addition of 35%), without adding the attractant of the present invention; feed 2 is a low fishmeal control group (fishmeal addition of 30%), without adding the attractant of the present invention; feed 3 For the low fish meal control group (30% fish meal addition), the food attractant of the present invention was added. The specific feed formula is shown in Table 1. There were 3 replicates per treatment group, and 50 fish per replicate. The test fish were kept in an indoor glass fiber reinforced plastic aquarium (90cm in diameter, 45cm in water depth). Before the formal test, the test fish were fed with commercial feed for 7 days to adapt to the test environment. The test is spring water, the water temperature is 9.0~14.2℃, and the dissolved oxygen is more than 8.0mg/L. Manual feeding is performed twice a day, and the feeding rate is 2 to 3% of body weight. The test was carried out for a total of 30 days.

[0021] Group
[0022] Note: The data in the table is the sample mean±standard deviation (x±sd); the same column without the same letter indicates that the difference is significant (P<0.05).
[0023] It can be seen from Table 2 that the weight gain rate and specific growth rate of the test fish of feed 1 and feed 3 were significantly higher than that of feed 2 (P<0.05), and the feed coefficient of the test fish of feed 1 and feed 3 was significantly lower than that of feed 2 (P<0.05). ). It can be seen that adding compound attractants to the feed of Zerro salmon can increase the weight gain rate and specific growth rate of the test fish, and reduce the feed coefficient.

Example Embodiment

[0024] Specific embodiment three: This embodiment is different from the specific embodiment one in that the compound attractant for jerome salmon is composed of 25% dimethyl-β-propionate Thiatin, 25% taurine, 12% by mass. % Glutamic acid, 13% alanine, 12% glycine and 13% sodium inosinine are mixed. Others are the same as the first embodiment.
