We discuss litter amendments, ammonia control strategies, the pros and cons of the built-up litter system vs. the changing-out system, the evaluation of emerging technologies, previous game-changers in disease prevention in poultry, and much more."If you don't follow three days of composting, turn the litter, and let it go for another two to three days, then you'll achieve almost a 100% kill."What you'll learn:(00:00) Highlight(02:35) Introduction and professional background(15:35) Built-up litter system vs. changing-out system(19:38) Key suggestions for litter management(22:30) Bacteria load in built up litter and potential risks(25:42) Role of extension and problem-solving in poultry care(35:06) Evaluation of emerging technologies (38:13) Changes in Necrotic Enteritis over time(41:25) Importance of collaboration and open communication in the industry(42:57) Final questionsMeet the guest: Dr. Ken MacklinExperience:Department Head and Professor at Mississippi State UniversityBackground:M.Sc. in Zoology/Animal Biology (Northern Illinois University)PhD in Poultry Science (Auburn University) The Poultry Podcast Show is trusted and supported by innovative companies like:- Protekta- DSM- Adisseo- AB Vista- Phibro- Eastman- Evonik- Natural Biologics- Berg + Schmidt𝗟𝗶𝘀𝘁𝗲𝗻 𝗼𝗻 𝗔𝗽𝗽𝗹𝗲 𝗣𝗼𝗱𝗰𝗮𝘀𝘁𝘀, 𝗦𝗽𝗼𝘁𝗶𝗳𝘆 𝗼𝗿 𝗮𝗻𝘆 𝗺𝗮𝗷𝗼𝗿 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺.Instagram: The Poultry Podcast Show LinkedIn: The Poultry Podcast Show

Approximately 244,000,000 eggs are set in incubators every week, and the average hatchability reported by the National Agricultural Statistical Service is 79.4%. That means only 79.4% of those eggs are hatching. As we know, this is a crucial productivity factor. Leticia Orellana, our guest, is conducting an in-depth study on hatchability and eggshell quality parameters, such as translucency and color intensity, and their relationship with other production factors. "In terms of hatchability, we found an almost 7% difference in hatchability when comparing a low translucent egg with a high translucent egg. You know, a 1% difference in hatchability is significant in the industry." - Leticia Orellana(00:00) Highlight(02:20) Introduction and educational background(03:38) Hatching eggs’ parameters (08:02) Quantifying eggshell quality: measuring parameters(12:20) Correlation between eggshell quality and hatchability(18:27) Eggshell color gradient and its correlation with hatchability and inner quality (23:51) Research's next steps (40:46) Ending of episodeMeet the guest: Leticia OrellanaExperience:Graduate Research Assistant (Auburn University)Background:B.Sc in Food Science and Technology (EAP Zamorano)The Poultry Podcast Show is trusted and supported by innovative companies like:- Protekta- DSM- Adisseo- AB Vista- Phibro- Eastman- Evonik- Natural Biologics- Berg + Schmidt𝗟𝗶𝘀𝘁𝗲𝗻 𝗼𝗻 𝗔𝗽𝗽𝗹𝗲 𝗣𝗼𝗱𝗰𝗮𝘀𝘁𝘀, 𝗦𝗽𝗼𝘁𝗶𝗳𝘆 𝗼𝗿 𝗮𝗻𝘆 𝗺𝗮𝗷𝗼𝗿 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺.Instagram: The Poultry Podcast Show LinkedIn: The Poultry Podcast Show

The growing threat of antimicrobial resistance makes it imperative to explore alternative strategies of sustainable and responsible poultry farming. Therefore, understanding the mechanisms behind the action of antibiotic alternatives can significantly improve bird gut health and consequently, food safety. In this episode, Dr. Morgan Farnell shares his experience working with avian microbiology and immunology. In particular, he talks about understanding the use of products that are alternatives to antibiotics in poultry and some biosecurity aspects related to disease outbreaks.“I think the toughest thing about studying antibiotic alternatives is that, even though they are alternatives, you're not going to see the same effects." - Dr. Morgan Farnell(00:00) Highlight(02:28) Introduction(05:08) Research history(08:04) Dealing with disease outbreaks like high-path avian influenza(11:14) Depopulation in situations of disease outbreak(13:37) How alternative products to antibiotics function(20:54) Control standpoints in the pre-harvest (25:24) Ag education(28:14) Modulating bird immune response(36:20) Final thoughts and some adviceMeet the guest:  Dr. Morgan FarnellExperience:Current: Associate Professor at Texas A&M University Past: Associate Professor at Mississippi State UniversityBackground:Ph.D., Veterinary Microbiology (Texas A&M University)M.Sc., Poultry Science (Texas A&M University)B.Sc., Agri-Business (Southern Arkansas University)Connect with the guest!𝗟𝗶𝘀𝘁𝗲𝗻 𝗼𝗻 𝗔𝗽𝗽𝗹𝗲 𝗣𝗼𝗱𝗰𝗮𝘀𝘁𝘀, 𝗦𝗽𝗼𝘁𝗶𝗳𝘆 𝗼𝗿 𝗮𝗻𝘆 𝗺𝗮𝗷𝗼𝗿 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺.The Poultry Podcast Show is trusted and supported by innovative companies like:- JBI- Protekta- DSM- Adisseo- AB Vista- Phibro- Eastman- Evonik- Natural Biologics- Berg + Schmidt

One of the primary aspects of the welfare of laying hens is the living conditions in which they are raised. In recent years, there has been increased awareness of the importance of providing hens with adequate space and enriched environments, so alternatives to cage-based housing (such as cage-free, free-range, and enriched colony housing) have emerged. These systems encourage the natural behavior of hens by offering them more space and resources, such as perches and nesting areas. In this episode, Dr. Tina Widowski discusses her current research on the topic along with different aspects of these non-cage systems, as well as the responses of the birds to them and their behavioral needs.“Nesting, foraging, perching, and dust bathing: those are the things that we try to accommodate in any kind of welfare-friendly system, while at the same time keeping the animals healthy.” - Dr. Tina Widowski(00:00) Highlight(02:24) Introduction(04:49) Guest’s career path(08:06) Hot topics on the laying hen industry(09:55) Transitioning birds from cages to cage-free systems(14:12) Understanding non-cage systems(18:26) Monitoring the behavior of laying hens(22:43) Behavior differences between brown and white birds(31:44) Feather pecking(38:28) Keel damage(45:29) The three final questionsMeet the guest:  Dr. Tina WidowskiExperience:Current: Professor of Applied Animal Behavior and Welfare; Egg Farmers of Canada Research Chair in Poultry WelfareBackground:Ph.D., Epidemiology (the University of Illinois)M.Sc., Animal Science (the University of Illinois)B.Sc.; Ecology, Ethology, and Evolution (the University of Illinois)Connect with the guest!𝗟𝗶𝘀𝘁𝗲𝗻 𝗼𝗻 𝗔𝗽𝗽𝗹𝗲 𝗣𝗼𝗱𝗰𝗮𝘀𝘁𝘀, 𝗦𝗽𝗼𝘁𝗶𝗳𝘆 𝗼𝗿 𝗮𝗻𝘆 𝗺𝗮𝗷𝗼𝗿 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺.The Poultry Podcast Show is trusted and supported by innovative companies like:- JBI- Protekta- DSM- Adisseo- AB Vista- Phibro- Eastman- Evonik- Natural Biologics- Berg + Schmidt

Infectious coryza (IC) is a contagious bacterial disease that causes respiratory problems in chickens and hens and can decrease egg production, increase mortality, and decrease poultry growth rates. Considering that it is possible for birds carrying the bacterium to spread it to other susceptible individuals within the flock or to neighboring farms, management practices, biosecurity measures, and vaccination are all part of preventing and controlling IC. In this episode, Dr. Rodrigo Gallardo Cunazza discusses different aspects of IC, including challenges, implications, biosecurity measures, management, vaccination, and treatment.“It must be a priority to focus on infectious coryza prevention by reducing the loads, doing good vaccination and knowing which strains are floating around and causing the disease." - Dr. Rodrigo Gallardo Cunazza(00:00) Highlight(01:56) Introduction(05:03) Top areas of research on poultry(08:42) Infectious Coryza (IC)(13:07) Cage-free systems and disease challenges(15:56) Prevention, treatment, and management of Coryza(22:57) The next steps on Coryza research(28:57) Coryza treatment around the world(36:32) Final questionsMeet the guest:  Dr. Rodrigo Gallardo CunazzaExperience:Current: Professor in Poultry Medicine at the University of CaliforniaPast: Assistant Professor and Associate Professor at the University of CaliforniaBackground:Ph.D., Avian diseases (Auburn University)D.V.M.
