Duckweed, an aquatic plant rich in protein, holds promise as a sustainable plant-based protein for companion animals. However, the potential of duckweed protein in dog and cat diets has been relatively unexplored. In our study, we assessed the viability of incorporating duckweed protein into dog and cat diets by examining nutrient digestibility, stool consistency, and diet palatability. Our findings indicate that including duckweed protein in dog diets maintains acceptable nutrient digestibility and improves stool quality, although it may impact diet palatability. For cats, duckweed protein inclusion led to reduced nutrient digestibility, looser stool, and lower diet palatability. While duckweed protein shows potential as a suitable plant-based protein source for dogs, further development is necessary before considering it for cat diets.
