Accurately defining our nutrient loadings when formulating diets is essential for nutritionists. If we are not accounting for enough enough energy from hindgut fermentation, we may be over feeding energy during certain stages of production. In this episode with Dr. Ruurd Zijlstra, we discuss a study he conducted measuring the digestible and fermentable fractions of certain grains to hopefully more accurately predict the net energy of these feedstuffs. Take a few minutes and give this a quick lis...
Even with different types of vaccines available for PEDv, it still is a common issue that swine farms struggle with. In this episode, Dr. Clayton Johnson interviews Dr. Brent Sexton about his experiencies with PEDv vaccines and how he has been utilizing a different vaccination method to try and increase the effectiveness of the vaccine in his sow herds. Take 9 minutes out of your day and give this a listen!
Meet the guest: Dr. Brent Sexton grew up on a farm near Rockwell City, Iowa. He ...
We all know about the importance of calcium and phosphorus in the diet, but can we be more precise with our feeding techniques? In this episode with Laura and Dr. Tom Crenshaw, they discuss Tom’s work by diving deeper into the cation and anion balance as well as certain instances where we may be over-feeding calcium or phosphorous without knowing it.
What you will learn:
1. Current Ca:P ratios in the industry
2. Can the same ratio be used for all sows?
3. Cation-anion balance
4. Pot...
Morning - your weekly 9-minute swine nutrition research update is here:
Zinc oxide is a wonderful tool for nursery pigs. However, there have been concerns about the environmental impact ZnO can have. Several research studies have been performed to identify potential alternatives to ZnO that are more environmentally friendly. In this episode I talk with Dr. Neil Jaworksi as we discuss a trial that he performed at Trouw Nutrition that may provide a viable alternative to ZnO by targeting desirable...
Disease classification is a very important aspect for both swine producers and veterinarians. It helps provide a roadmap for how to manage viruses within herds, and PRRSV has been a major problem for the swine industry for many years. In the first episode, Dr. Derald Holtkamp shares with me Dr. Clayton Johnson about the many years he has spent developing his swine herd PRRS classification system. Listen to this short episode to learn more about it!
Meet the guest: Dr. Derald Holtkamp is a ...
Market demands change with every single generation. The types of products we want today will not be the type of products our kids or grandkids will want when they get older. With the current demands from consumers today, how can the pork industry better create an efficient future for itself tomorrow? In this episode, Dr. Greiner talks with Dr. Jim Lowe about similarities with the beef industry and the pork industry and how we as producers should be marketing our products to best help our retaile...
Over the last several decades there have been several suggestions on how to feed the gestating sow, and recently several of those practices have been debunked and have actually shown to have more detrimental effects than they do beneficial effects.
I think part of the reason we have been making these discoveries is that we now have a greater understanding of the sows’ physiological processes.
For starters, one main theory that has been backed up by several studies is that the sow prioritizes...
