This study investigated how targeted light exposure during egg incubation (in-ovo) and after hatching (post-hatch) influences growth performance, feed efficiency, and survivability of broiler chickens under tropical conditions. Poultry production in warm climates is increasingly challenged by heat stress, which compromises feed intake, growth rates, and survival. Photo stimulation using specific light wavelengths has emerged...Read More

Cage aquaculture in Lake Victoria, Tanzania, has expanded rapidly over the past decade, providing livelihoods and contributing to national fish supply. However, this intensification has been accompanied by increasing disease outbreaks that threaten productivity, fish welfare, and farmer incomes. This study investigated the major bacterial pathogens responsible for infectious diseases in cage-farmed Nile tilapia (Oreochromis...Read More
