Brief Summary of Minutes of Annual Meeting

Brief Summary of Minutes of Annual Meeting:

·         May 13th, Okotoks, Alberta: Participants met at Feedlot Health Management Services and learned about research and services the company provides. Participants also toured a commercial feedyard that used Feedlot Health Management Services.

·         Welcome, introductions, agenda review: the meeting started with a general welcome to the group. Introductions were done with the whole group, which included not only NCCC-308 members but also students and guests who were in attendance. 

·         Administrative Update: Steve Smith provided an administrative update on the proposed changes & reorganization to the AFRI program, as well as staffing/hiring status at USDA. 

·         Administrative Update: John Lawrence provided an overview of NC Multistate Administration and an update on reporting guidelines. John Lawrence will be stepping down as NCCC-308 advisor and Steve Loerch will assume this role.

·         Meeting planning for 2020: meeting will be hosted by Tara Felix at Penn State May 12 to 14, 2020

·         State report highlights: updates regarding progress towards committee objectives were provided by members

·         Lethbridge Research and Development Centre researchers provided research updates

·         Members toured Lethbridge Research and Development Centre facilities

Accomplishments: Cattle are being fed to larger weights much more efficiently. However, public concern over the use of traditional technologies such as growth promotants and antibiotics has challenged the beef industry. Members of the NCCC-308 multistate group are investigating the role that stress and digestive processes play in disease prevention and are developing new feeding strategies and feed additives that improve animal health, increase growth, and enhance meat quality.

Short-term outcomes: None to report.

Outputs: Members of the NCCC-308 multistate group have organized 38 meetings that discuss feedlot nutrition and management, presented 25 scientific presentations, and published 35 peer reviewed journal articles. Important findings include:

• Trucking stress decreases cattle growth performance and compromises immunity. Overcoming the oxidative stress induced by trucking may result in less days cattle must be in the feedlot to reach desired end body weights. (IA)
• Copper status of cattle may influence growth response to beta agonists and anabolic implants. (IA)
• Antibody titers to BVDV Type I linearly improved with vitamin E supplementation (IA)
• Cattle exhibited similar physiologic and immunologic responses to stress (exposure to CRH+VP) regardless of whether exposure was for 1 day or 4 consecutive days (WTAMU).
• Selective use of antibiotic at feedlot entry based on white blood cell count decreased antibiotic usage and was as effective as metaphylaxis at decreasing morbidity (MI)
• Aspirin induces leaky gut and can be used as a model to study gastrointestinal tract barrier dysfunction in feedlot cattle (IN).
• Fructose supplementation to neonatal Holstein calves increased small intestinal mass and glucoamylase activity but not influence lactase, isomaltase, and maltase in different segments of the small intestine (NDSU).
• Leucine supplementation did not influence N balance, increased serum leucine concentration, linearly decreased serum methionine and alanine concentration, and linearly increased pancreas weight (NDSU).
• Parasite control of cows and calves during the pre-weaning phase improved carcass quality of calves. (IA)
• Despite concerns that monensin efficacy has diminished in recent years, it was demonstrated to still increase daily gain and end-weight of stocker cattle, while providing gain and efficiency advantages when provided during the finishing phase (OK)
• Feeding either the DFM-Enzyme blend improved gain and feed conversion efficiency after 28 d but not after 49 d on feed (MN).
• Inclusion of Bacillus subtilus during the feedlot receiving period improves cattle health and performance (WTAMU).
• Administration of a DNA immunostimulant did not mitigate viral (IBRV) recrudescence following stress challenge with dexamethasone (WTAMU).
• Steers fed at restricted intake gained less and converted feed dry matter to gain less efficiently than those that were fed ad libitum. However, cattle fed ad libitum used intake above that achieved by restricted-fed cattle at a poorer feed conversion efficiency (MN).
• The 2016 NASEM model under predicts performance of lightweight beef steers by as much as 29%. (IL)
• Collecting rumen fluid through a suction strainer via the rumen cannula is preferred for conducting in vitro dry matter disappearance assay to predict ruminal degradation of various feedstuffs. (IL)
• The USDA yield grad equation to predict cutability of beef carcasses does not accurately evaluate the Jersey breed of cattle (OH).
• The Fukutsuru line of Wagyu cattle have a similar feed efficiency to Angus cattle and has greater growth and less marbling than the Yasufuku line of Wagyu cattle (OH).
• Nutrient restriction during gestation reduced pancreatic digestive enzyme activities, whereas nutrient restriction during mid-gestation followed by realimentation increased small intestinal lactase activity (NDSU).
• Dietary omega-3 fatty acids in cow diets alters cow conception rates and influences progeny muscle gene expression (IN).

Activities:

• Conducted over 22 nutrition and management studies.
• Organized 38 meetings that discuss feedlot nutrition and management.
• Presented 25 scientific presentations.
• Published 35 peer reviewed journal articles.
