Challenge: High Production Costs and Limited Ingredient Awareness
Factors such as high production and processing costs as well as lack of awareness among pet owners and manufacturers assist to hinder the growth of the pet food microalgae market. Growing high value microalgae like spirulina, chlorella and schizochytrium specifically for pet food involves controlled environments, advanced harvesting and strict quality control which adds to the cost versus more conventional protein or fat sources.
Moreover, absence of knowledge amongst the consumers regarding nutritional value of microalgae when compared to conventional component such as meat, fish oil, or plant-based proteins restrict its widespread acceptance. These trends increase the challenge for manufacturers to justify elevated price points, especially in price-sensitive market segments.
Opportunity: Demand for Functional, Sustainable, and Hypoallergenic Pet Nutrition
In spite of these hurdles, the market shows promise on account of increasing demand for nutritionally premium, eco-friendly and hypoallergenic components for pet foods. Microalgae naturally contain omega-3 fatty acids, essential amino acids, antioxidants and vitamins, ideal for supporting pet immunity, skin health and cognitive function.
