This month’s entry in the “Beneficial Effect of American Cockroach Residue” competition is the study:
“Effects of Replacing Fishmeal with American Cockroach Residue on the Growth Performance, Metabolism, Intestinal Morphology, and Antioxidant Capacity of Juvenile Cyprinus carpio,” Xiaofang Zou, Chenggui Zhang, Bingyan Guo, Yu Cao, Yongshou Yang, Peiyun Xiao, and Xiaowen Long, Animals, vol. 14, 2024, pp. 3632.
The authors report: “This study evaluated the potential of substituting fishmeal with American cockroach residue in the feed of juvenile Cyprinus carpio. Replacing up to 40% of fishmeal with American cockroach residue significantly improved growth performance, antioxidant capacity, and immune function in juvenile C. carpio. However, replacing more than 40% of fishmeal may adversely affect intestinal health.”
