For every laying hen that is hatched, approximately one male counterpart also hatches. However, as roosters do not produce eggs, they are typically culled, or euthanized, at hatch. However, the culling of these day-old male chicks raises ethical concerns.
Antimicrobial resistance (AMR) has become a major concern for human and food-animal health. The key to better understanding AMR selection and spread is the resistome, the collection of all antimicrobial resistance genes and their precursors in the gut microbiome.
Clostridial dermatitis is an economically important disease of turkeys characterized by necrotic dermatitis and sudden death. Disease control strategies such as improved management and feeding probiotics have been only variably successful.
Antimicrobial use in poultry has become a proxy for antimicrobial stewardship, but these terms are not interchangeable, according to Michelle Kromm, DVM, MAM, Food Forward, LLC.
Enrichment improves the environment of an animal, to meet their behavioral needs and ultimately improve their welfare. Although the research related to enrichments for broiler breeders is sparse, there are several different types of enrichments that have been shown to be beneficial. In this article, Marcela Quino and Bethany Baker-Cook, PhD, describe a few that are particularly effective for broiler breeders.
Genome sequencing is key to controlling coccidiosis and the associated infections of necrotic enteritis in broilers, according to Mark Jenkins, PhD, USDA’s Animal Research Service.
In the face of threats such as highly pathogenic avian influenza (HPAI), one of the most pressing challenges for the poultry industry is to continually evaluate and improve depopulation strategies.
Saponins are well-known for their role in supporting bird performance, gut health and immune health. But in the latest research, scientists have uncovered greater insight into how different types of saponins, specifically quillaja, yucca and blends of the two, contribute to these outcomes.
Europeans have battled avian metapneumovirus (aMPV) since the 1980s. Today, live and inactivated vaccines keep aMPV under control in Europe and most of the world except in the US, according to Aris Malo, DVM, Royal Dutch Veterinary Association.
Proper litter management is a key factor in controlling Salmonella on the farm. Zac Williams, PhD, assistant professor of poultry management at the University of Arkansas, addressed this topic at the Delmarva Chicken Association’s 59th National Meeting on Poultry Health, Processing and Live Production.
Responsible antibiotic use is not a new concept to the poultry or other food-animal production sectors, but, says Randy Singer, DVM, PhD, it’s important to put the conversation back in the context of the Veterinarian’s Oath, and first ensure the safety, health and overall well-being of the animals.
Increased attention on animal welfare is driving the US poultry industry to innovate and work collaboratively to meet rising expectations of caring for laying hens.
