Super Shield EMS – An active approach to prevent early mortality syndrome/Acute hepatopancreatic necrosis disease (EMS/AHPND) in shrimp, is empirically proven effective in practice
After intensive monitoring, aquaculture specialists from Grobest Vietnam and Can Tho University have had positive scientific evaluation on the Super Shield EMS product line of Grobest Vietnam’s ability to maintain growth, enhance immunity, and proactively prevent shrimp against Early Mortality Syndrome (EMS).
A potential solution for preventing risks of EMS to Viet Nam shrimp farming
Can Tho University is a leading educational institution and technology transfer center in Vietnam, especially in aquaculture. In the past years, the university has gradually gained a reputation in assessing the quality of aquafeed, particularly shrimp feeds. This is the foundation for its collaboration with Grobest to conduct tests and experiments for the company’s products, including the Super Shield EMS.
Grobest’s Super Shield EMS has been tested by Can Tho University’s Faculty of Aquaculture from July 22nd, 2021 to September 14th, 2021 with two phases: Growth phase (Six weeks) and challenge phase (Two weeks). Three treatments were compared: (1) Control feeds; (2) Grobest’s daily feeds; (3) A combination of Grobest’s daily feeds in the growth phase and Super Shield EMS in the EMS challenge phase. The third treatment is key to testing and determining the effectiveness of Super Shield EMS in preventing EMS in farmed shrimp.
A combination of Grobest’s daily feeds and Super Shield EMS promotes healthy and well-grown shrimps.
Experts from Can Tho University’s Faculty of Aquaculture listed the result of the experiments as follows: (1) Grobest’s daily shrimp feeds promoted better growth and had better feed efficiency than the control feeds did; (2) The combination of Grobest’s daily feed and Super Shield EMS was the best immunity boost for shrimps out of the treatments; (3)The post-infection survival rate of shrimp fed on the combination of Grobest’s daily feed and Super Shield EMS was highest.
. Therefore, it can be seen that Super Shield EMS is the new solution to help farmers proactively prevent the risk of EMS in shrimps and maximize their profits.
The intensive, comprehensive, and objective monitoring procedure
To reach the above conclusions, experts from Can Tho University’s Faculty of Aquaculture and Grobest have maintained scientific transparency when conducting the experiments: The samples were anonymously submitted to ensure objectivity and rigor of the result. The first goal of this experiment is to evaluate the growth performance of shrimps by comparing different treatments based on three indicators: ADG (Average Daily Growth), SGR (Specific Growth Rate), and FCR (Feed Conversion Ratio). The second goal is to help all the stakeholders gain a closer look into the ability to promote shrimp’s immunity, such as calculating the phagocytosis rate in shrimp’s blood and the total of Vibrio spp. in the shrimp’s gut, and EMS pathogens post-infection survival rate.
As mentioned above, three treatments were conducted: (1) A control feeds; (2) Grobest’s daily feeds; (3) A combination of Grobest’s daily feeds and Super Shield EMS during the experimental infection research. The results showed that ADG and SGR of the second treatment is 23% and 9% higher than those of the first treatment respectively, while its FCR is 21% lower than that of the first treatment. The ADG and SGR of the third treatment is 18% and 7% higher than those of the first treatment respectively, whereas its FCR is 18% lower than that of the first treatment. Regarding the level of immunity, the phagocytic rate of shrimp fed on the combination of Grobest’s daily feeds and Super Shield EMS was 72% higher than that of control feeds; additionally, the Vibrio load in the gut of shrimp fed on the combination of Grobest’s daily feeds and Super Shield EMS was 36% lower than that of control feeds. Similarly, the figures in treatment (2) were 50% and 31% respectively compared to the control feed treatment.
Post-experimental results.
In conclusion, thanks to the assessment based on rigorous experimental procedures carried out by Can Tho University’s Faculty of Aquaculture, shrimp farmers can adopt the use of Grobest’s daily feeds in the growthstage and Super Shield EMS when shrimps are susceptible to pathogenic bacteria or when in adverse climate conditions to bring out the best result for the shrimp’s growth and immunity boost. This can be considered one of the achievements of Grobest Vietnam on its way of supporting the Vietnamese shrimp industry to ‘grow stronger, grow faster, grow sustainably’ and providing opportunities for farmers to reach the finish line with bumper harvests.
Super Shield EMS is the leading functional feed to help farmers proactively prevent – maximize profits against EMS.
>>Super Shield EMS was officially launched by Grobest Vietnam on February 21, 2022. The product was researched and developed using strictly selected high-quality, high-efficiency, and nutrient-rich ingredients with exclusive additives developed by Grobest, such as NutriRxTM, NutriHepto+TM, XtraGoTM. Super Shield EMS has many traits of a good product, namely increase survival rate, growth rate, productivity, and profit of shrimp farming, especially in unusual weather conditions and the rapid escalation of the disease outbreaks.
