A new study led by researchers at the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) has identified significant gaps in how bison producers manage gastrointestinal parasites. The research suggests that frequent deworming without diagnostic testing could contribute to drug resistance, emphasizing the need for bison-specific management strategies.
Gastrointestinal nematodes, commonly known as worms, pose a major health and economic challenge for bison herds. These parasites can cause diarrhea, poor weight gain, and reduced production, with severe infections potentially leading to the death of adult animals.
Dr. Kaylee Kipp, a recent VMBS doctoral graduate and associate professor of professional practice in ranch management at Texas Christian University, noted that both anecdotal and diagnostic evidence indicates bison face more parasitic issues than beef cattle.
The study aimed to fill a knowledge gap regarding parasite management in the southern and central United States. Previous research has largely focused on larger herds in northern states and Canada, leaving limited data on operations in Texas and neighboring states.
Dr. Guilherme Verocai, an associate professor in the VMBS’ Department of Veterinary Pathobiology and director of the Parasitology Diagnostic Laboratory, stated that understanding the basics of these operations was necessary, as herd sizes and management styles vary significantly.
