Application of PR-500 in Aquaculture

Application of PR-500 in Aquaculture

Undoubtedly, viruses and pathogenic diseases are the biggest challenges facing the aquaculture industry. Despite the use of large quantities of disinfectants, antibiotics, and even vaccination, the control of diseases is still due to the complexity, variability and operational limitations of the water environment. It is difficult to achieve the desired effect. The main functional components of PR-500 Prosperazine are Glucan and Mannan. The former can stimulate lymphocytes to produce and activate Macrophage, which has a variety of pathogens. Significant adsorption. This product can enhance the immune system function of aquatic animals, improve the ability of anti-virus infection, and can effectively inhibit the invasion of pathogenic bacteria, playing the dual role of vaccines and antibiotics. Therefore, the PR-500 cell wall has a wide range of applications in aquaculture. 1. Prazisol PR-500 can improve vibrio infection in trout survivorship trials confirmed that feeding PR-500 can increase the survival rate of Atlantic salmon infected by cold water vibrio from about 5% to 70% At the same time, the combined use of PR-500 and vaccines provides stronger and longer-lasting immune protection, which can increase the survival rate of infected salmon to 90%. Treatment Vaccine Survival Rate PR-500 + 135/150 (90%) Conventional Feed + 84/150 (56%) Conventional Feed - 25/150 (17%) Note: PR-500 Feeding 3 Weeks Before Infection 3000ppm. 2.

Prosugin PR-500 improves Vibrio infection ability of shrimps Days after infection 0 2 4 6 8 10 12 14 16 Control group 100 80 78 75 65 55 18 15 15 Test group 100 100 90 87 87 75 68 65 65 Note: 1 The PR-500 dose is 3000 ppm. 2 feeding PR-500 2 weeks before infection The effect of PR-500 PRS on the growth of shrimps The experimental and control groups each had 5 mu of ponds, and the time for seedlings was the same, and the shrimps were from the same nursery pond. The experimental group added 0.5% PR-500 to the control diet. Project control group Experimental group Growth rate % seedling tail/Mu 50000 50000 Trial shrimp weight/tail 5.88 5.71 Trial shrimp weight/tail 11.11 14.70 +32.3% Gain weight/test tail 5.23 8.99 +71.9% Total output kg/pool 889 1507 +69.5% feed conversion ratio 2.75 1.87 +32% survival rate 32 41 +28.1% 5. Prostaglandin PR-500 can also be used to control bacterial enteritis in carp: add 0.3-0.5 to feed % PR-500 Prostaglandin can reduce the incidence of enteritis by 30-50%. At the same time, it can also stimulate the appetite and promote growth. 6. PR-500 PR-500 is effective in raising the survival rate of crab seedlings: PR-500 Prosugium is fed at the same time as 10-20% of diet and fed with crab seedlings. For a week, the survival rate of crab seedlings can be 52%. Increased to 79%. Company name: Beijing Aidi Technology Co., Ltd.
