14 FEED•LOT  December 2017 INDUSTRY & INNOVATION ISSUE growth. The question for us at All- tech is, how can we get those good genes activated?" Do specific nutritional regimens turn on good genes or bad genes? Absolutely, says Lawless. "Looking at a feedlot additive, like EPNIX, gives us a more precise way of knowing what is happening with an animal," he said. "One of the ma- jor things we learned is what you feed matters, and specifically when you feed it plays a really critical role in overall performance." EPNIX works independently of beta-agonists or antimicrobials, so it can be used synergistically with all conventional feeding strategies. EPNIX is customized specifically for the life stage of feedlot cattle, and is packaged with 100% organic trace mineral supplementation. EPNIX is also Feed Verified by Where Food Comes From ® for easy use in Verified Natural (NE3) and NHTC programs, all without the need of a VFD. To prove its efficacy Alltech has partnered with leading feedlot companies over the last two years to conduct large-scale research across North America. The focal point of the research has been to examine the real-life impact on cat- tle and the bottom line for feedlots. "At the end of the day, it gives a positive return on investment for the producer and more meat to the packer. It's a win-win" Lawless said. When it comes to digging deeper into science to find new feeding strategies, Lawless said, "It's al- ways an idea until you can develop a product and test it out. It worked in the lab and now we're excited to see it working for feedlots." Don't feed the fever Keeping cattle healthy — and encouraging quicker recovery from illness — helps animals direct their energy towards growth and production. Any disease challenge requires cattle to mount an im- mune response. In the zero-sum game of livestock production, this means resources are pulled away from building muscle mass or pro- ducing milk. "It's extremely important for us to provide the animal with the opti- mal environment and tools to main- tain a healthy immune system," says Ty Schmidt, Ph.D., PAS, Assistant Professor of Muscle Biology/Physi- ology at the University of Nebraska – Lincoln. "When we have an animal that mounts an immune response, it has to have enough energy to get the immune system going, fight the infection, then come back and con- tinue producing." In beef cattle, there's no more challenging time than after the stress of transportation. The indus- try has long battled bovine respira- tory disease complex (BRDC) in newly received calves. In fact, the average pull rate for BRDC in feed- lot cattle has remained around 30 percent for years, even with ad- vances in vaccines and antibiotics to tackle both viral and bacterial BRDC causes. Probiotics, such as ProTerna- tive ® (Saccharomyces cerevisiae boulardii CNCM I-1079) are gaining popularity as a tool to help support animals at risk for BRDC. The ac- tive dry yeast (ADY) probiotic has been proven to positively activate the immune system of cattle during times of stress by supporting bac- terial communities in the lower in- testinal tract. In a recent trial, Dr. Schmidt evaluated yearling steers supple- mented with S. c. boulardii CNCM I-1079 for 28 days at two different N u t r ig e n o m ic t e c h n o lo g y A l l t e c h i s t a r g e t i n g f e e d l o t t e c h - nolog ie s down t o t he g e ne le v e l with EPNIX, ® a nutritional ap - p r o a c h t o d r iv e c a r c a ss we ig h t g a in a n d i m p r o v e d r e s s i n g p e r c e n t a g e .

Or in some cases, they revitalize an existing product. Here's a recap of a few innovative ideas and recent research.
