Bone and leg health issues are among the top five common concerns for broilers, noted Gigi Lin, DVM, DACPV, adding that “Lameness can indicate not only a potential disease issue but is a welfare and economic concern.” Lin, a veterinary consultant with Canadian Poultry Consultants, Ltd, was featured in the 2025 Canadian Poultry’s Broiler School Series webinar presentation, “Understanding and Managing Lameness in Broilers.”
Alternatives to antibiotic growth promoters can maintain broiler performance. But replacing antibiotics is not a simple matter of like-for-like replacements, according to Doug Korver, PhD, professor of poultry nutrition at the University of Alberta.

Post-mortem exams help determine mortality causes and which health challenges birds are encountering. But conducting necropsies on healthy birds can also provide the perspective needed to distinguish between what’s normal and abnormal for a particular flock.
Pathogenic Enterococcus cecorum is proving to be a growing problem on broiler farms, and infection extends beyond bird-to-bird contact to the farm environment, according to a study led by Martine Boulianne, DMV, PhD, DACPV, at the University of Montreal.

Faced with the emerging disease threat posed by avian metapneumovirus (aMPV), the USDA is allowing the importation of three vaccines from Boehringer Ingelheim: the live virus products NEMOVAC™ for use in chickens and AVIFFA RTI for use in turkeys and chickens, as well as the TUR-3 inactivated vaccine for primary vaccination of both turkey and chicken flocks against aMPV subtype B.
Calcium plays a key role in poultry feed conversion. In addition to bone density, muscle contraction and other critical functions, calcium affects the efficiency of turning food into weight gain. But in broilers, it’s not just the amount of calcium that matters. What really counts is bioavailability: how much of that nutrient the bird can actually use.
