Stopping SARS-CoV-2 along the farm-to-plate supply chain

Texas A&M AgriLife-led study tracking down cause, transmission of coronavirus in food processing From live cattle entering a packing plant to the consumer’s kitchen table, a Texas A&M AgriLife-led research project aims to develop an accurate way to predict potential contamination with SARS-CoV-2, the virus that causes COVID-19, throughout the food supply chain. Sapna Chitlapilly Dass, Ph.D., a meat science research assistant professor in the Texas A&M College of Agricultural and Life Sciences Department of Animal Science, will lead the two-year, $1 million U.S. Department of Agriculture National Institute of Food and Agriculture… Read More →

Meat Perspectives: Ground beef basics

By Jeff savel and Kerri Gehring Ground beef remains one of the most popular forms of beef consumed in the United States. Some estimates report that up to 65% of all beef consumed is in the form of ground beef. It is one of our go-to foods, and we are reminded of this during the COVID-19 pandemic as well as other times where economic or other situations have us staying at home and wanting something easy to prepare and comforting to eat. Continuing cyclical interests in various iterations… Read More →

AgriLife Research expert uses math to predict environmental impacts of livestock production

‘Smart-farming’ approach models sustainable, intensive protein production In an effort to make sure our animal protein supply is sustainable, a Texas A&M AgriLife researcher is using mathematical modeling to connect the dots between increasing production efficiency in livestock operations and minimizing environmental impacts. Luis Tedeschi, Ph.D., an AgriLife Research ruminant nutritionist, and his team in the Texas A&M University Department of Animal Science recently published a paper on sustainable livestock intensification, Modelling a Sustainable Future for Livestock Production, in Scientia. The team concluded that an integrated smart-farming approach… Read More →

Peak performance important to cow-calf operations amid pandemic-induced price fluctuations

AgriLife Extension program offers financial, production analysis and benchmarking to identify opportunities, weaknesses With the COVID-19 pandemic, cattle prices have been on a roller coaster. Now is a good time to analyze performance to make sure your operation is as efficient as possible, according to a Texas A&M AgriLife Extension Service specialist. Pancho Abello, AgriLife Extension economist, Vernon, said the agency’s long-running Beef Cattle Standard Performance Analysis, SPA, program is a good way for cattle producers to look at their bottom line and make adjustments to their operations. “Opportunities for change… Read More →

Beef cattle physiologist joins AgriLife Research

Research to focus on reproduction physiology George Perry, Ph.D., was recently hired as a Texas A&M AgriLife Research cattle physiologist and associate professor in the Texas A&M Department of Animal Science. Perry said he was excited to join AgriLife Research at the Texas A&M AgriLife Research and Extension Center in Overton. He said he looks forward to producing research that will directly impact the beef cattle industry in Texas and the southern U.S. Decades of cattle physiology research data at the Overton center will speed his transition and help him begin work… Read More →

Former students named 2020 Distinguished Alumni of Texas A&M

Animal science, agricultural economics graduates among 12 honored Twelve Aggies have been selected as the 2020 recipients of the Distinguished Alumnus Award, the highest honor bestowed upon a former student by Texas A&M University and The Association of Former Students. The College of Agriculture and Life Sciences celebrates the late C.M. Cocanougher, DVM ’53 and Lt. Gen. Randolph House ’67 as they have embodied the true Aggie spirit far beyond their time on campus. “We are proud of these wonderful former students and all of their accomplishments and contributions,” said Texas… Read More →

Minerals Matter | Impact on cow reproduction

Trace mineral supplementation not only increases reproduction efficiency, if supplied during gestation, it is showing results of heavier animals at weaning. The female is the factory on the ranch. She is responsible for raising a calf year after year, but this is not possible if she isn’t in proper nutritional health. “The impact of mineral supplementation is as or even more substantial than energy and protein for proper reproductive health,” says Reinaldo Cooke, Texas A&M Beef Cattle Production Specialist. “Minerals have a huge impact on reproduction.” A lot… Read More →

Prenatal stress increases skeletal muscle mitochondrial volume density and function in yearling Brahman calves

Guy, CP, CL Wellman, DG Riley, CR Long, RD Randel, TH Welsh, Jr., SH White-Springer. 2020. Abstract We previously determined that prenatal stress (PNS) differentially affected methylation of DNA from leukocytes of 28-d-old calves. Specifically, COX14 (cytochrome c oxidase (COX) assembly factor) and CKMT1B (mitochondrial creatine kinase U-type) were hypomethylated and COA5 (COX assembly factor 5), COX5A (COX subunit 5A), NRF1 (nuclear respiratory factor 1), and GSST1 (glutathione S-transferase theta-1) were hypermethylated in PNS compared to non-PNS calves (P≤0.05). Our current objective was to test the hypothesis that… Read More →

Select skeletal muscle mitochondrial measures in Thoroughbred weanlings are related to race earnings and sire

Guy, CP, CM Latham, RN Owen, AL Fowler, SH White-Springer. 2020. President’s Oral Pick: Abstract QuanPfiable, cellular differences of individuals are not widely used in breeding and training decisions in the equine industry. Our objecPve was to determine if mitochondrial parameters in weanling Thoroughbreds were related to sire or lifePme race earnings. We hypothesized that weanling skeletal muscle mitochondrial capacity would be posiPvely correlated with race earnings. Gluteus medius muscle samples were collected from racing-bred Thoroughbred weanlings (n=139; mean±SD; 6.0±0.4 mo) from 40 different sires over 3 years… Read More →
