Cattle efficiently consume various by-products like distillers grains and soyhulls in their diets, proving beneficial and cost-effective. The marine microalgae industry, facing a similar by-product challenge, seeks a potential solution.
These small marine plants can convert sugars and carbon dioxide into essential metabolites, including n-3 fatty acids. This characteristic positions marine microalgae as a sustainable alternative, potentially alleviating pressure on wild-caught aquaculture. The production of algae oil results in a by-product known as condensed algae residue solubles (CARS). With increased CARS production, the potential for more sustainable practices grows.
A comprehensive study involving approximately 400 predominantly Angus, British crossbred steers took place over 148 days. The research examined three diet variations, incorporating CARS at 0%, 2.5%, and 5%.
Findings highlighted promising outcomes with a 2.5% inclusion of CARS in the diet, showcasing improvements in final body weight, daily weight gain, and feed efficiency. However, a 5% inclusion of CARS led to reduced feedlot performance.
This study illustrates the potential benefits of integrating CARS into cattle diets while emphasizing the importance of moderation. While a moderate inclusion of CARS displayed positive impacts, higher levels adversely affected feedlot performance.
