AMR forum tackles ‘complex, global issue’

By Tim Lundeen Antimicrobial resistance (AMR) is a “complex, global issue to be addressed globally,” according to Dr. Sara Steinlage with Elanco in introducing an April 2 forum “Antibiotics in Animal Agriculture: What You Need to Know,” organized by the New York Academy of Sciences (NYAS). The forum was the culmination of a year-long process looking into the topic of AMR in animal agriculture, according to Dr. Gilles Bergeron, who heads the nutrition science section at NYAS. The effort, sponsored by Elanco, resulted in five new papers published… Read More →

Cattle production offers sound environmental ‘hoof print’

By Jennifer M. Latzke The proposed “Green New Deal” has thrown a lot of focus onto cattle lately—a plan that would limit cattle production to an extent in an effort to curb their greenhouse gas “hoof print.” But recently released research quantifies the role cattle play in the natural carbon cycle, and how they serve an upcycling purpose in turning feedstocks into higher value protein that humans can eat Baseline measurements Al Rotz is an an agricultural engineer with the U.S. Department of Agriculture’s Ag Research Service and… Read More →

A different cut of beef

By Cass Rains FAIRMONT, Okla. — Linda Woodruff and her family raise the Japanese breed of Wagyu cattle on their family farm, Silverwood Wagyu, east of Fairmont. The name comes from “Wa,” which means Japanese, and “Gyu,” which means cow. Silverwood also is a hybrid name, as Woodruff’s son, Jeremy, manages the farm’s website and her daughter, Stacey Silver, and Stacey’s husband, Justin, manage the day-to-day operation of the farm. “It’s a family farm,” Woodruff said. “We all work together.” Growing up on a farm Woodruff’s father was born in 1914 and lived about… Read More →

2018 ANSC Brazil Study Abroad: Comparative Ruminant Production

Writers: Jordan Adams and Madeline Rivera It is every college student’s dream to have the opportunity to participate in a study abroad.  Visit a foreign country, learn a different language, experience another culture, make new friends, and learn something that we never knew about ourselves. During the summer of 2018, nine animal science students and one biomedical science student had the opportunity to study abroad in Brazil. The objective of the study abroad was to compare ruminant production schemes in the northeastern and southeastern regions of Brazil to… Read More →

How to get the most out of your limited hay supply

With the possibility of a dry spring leading to an even drier summer, getting the most out of your hay is critical. By Larry Stalcup Ranchers in a big swath of the Southwest and High Plains were in varying levels of drought; some have gone nearly five months with no measurable rain or snow. Fire danger is critical. With those conditions, ranchers can only make good winter forage go so far without depending heavily on hay. But poor hay quality, storage and feeding practices can easily cut into an already tight profit potential. “The… Read More →

Cattle Are “Up-Cyclers”

By: John Maday Among all the discussion about efficiency and sustainability in food production, beef’s critics often leave out a critical point—cattle eat things we cannot. They turn grass, corn stalks, wheat straw and byproducts such as distillers’ grains and cottonseed meal into high-quality protein for human consumption. While it also is true cattle eat products such as corn and soybean meal, which could be used in human diets, analysis indicates beef has a good story to tell regarding the ratio of human-edible nutrients invested to human-edible nutrients… Read More →

Second edition of The Ruminant Nutrition System published

The first edition of The Ruminant Nutrition System: An Applied Model for Predicting Nutrient Requirements and Feed Utilization in Ruminants was published in October 2016. Since then we have received much positive feedback, which has encouraged us to revise and expand it. In this second edition, we have updated concepts and added new information, clarified and enhanced the discussions of important topics, included new and improved and standardized existing graphics and illustrations, rearranged some of the text, and included indexes for subjects and authors. Although we believe this second edition… Read More →
