Discussing EMS disease with farmers at their pond.

Our results showed that catecholamine stress hormones Dopamine and Norepinephrine increase the motility (an important virulence factor) of Vibrio parahaemolyticus. Therefore, to prevent the provocation of EMS, we have advised farmers to avoid the stress condition for shrimp as much as possible, especially during the initial culture stage. Given that catecholamine sensing seems to control virulence factors that are important in the early stages of infection (motility), interfering with it might be a way to decrease transmission of EMS between animals.

My research results indicated that providing perches and dust baths for broilers is of great benefit for chickens in terms of both animal welfare and economic outcome. Therefore, when I went to farm households, I gave them advice about this. Many chicken farms (in the free-range production system) have now applied perches and dust baths for broilers. The feather coverage of the chicken is better and farmers can sell their chickens for a higher price.

We identified five high-yielding local varieties (Azigokouivovo, Tintablana, Souhouloumankpa, Tamapoika and Tincocouanpépiatou) and produced their seeds to make available to producers. A breeding program will be set up to produce high-yield, short-cycle varieties. Vigna subterrenea.
