Detection of Burkholderia mallei in Microbiological Culture: A Comparative Analysis of PCR Primer Sets

Pathogens
Glanders is a highly contagious and often fatal zoonotic disease of equids caused by Burkholderia mallei, a pathogen of significant concern due to its potential for bioterrorism.

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

American Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Beef Cattle

The type of cattle feeding system significantly influences the final slaughter weight, degree of carcass fatness vs. muscle, and beef quality. Three basic systems, based on the age at which cattle are finished and marketed, include fattening calves, young cattle and bulls, and adult cattle (mainly cull cows).

Carbon footprint of beef cattle production in integrated systems of the Brazilian Cerrado

Frontiers in Sustainable Food Systems
Prediction of soil organic carbon (SOC) stocks, tree carbon stocks, enteric emissions, and beef production is essential for evaluating low-carbon livestock systems.

The Herfindahl neutral point: A firm‐level threshold for managing market concentration with evidence from US hog packing

American Journal of Agricultural Economics, EarlyView.
Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

From Traditionally Extensive to Sustainably Intensive: A Review on the Path to a Sustainable and Inclusive Beef Farming in Brazil

Animals
Brazil is the second largest beef producer and a leading exporter, contributing to some 3000 t CWE in global markets (27.7% of market share). The sector has experienced substantial development, but yields remain far below potential, and there are growing

LncRSFD Alternative Splicing Modulates the Proliferation and Differentiation of Adipocytes Through Sponging miRNAs

Animal Research and One Health, EarlyView.
This study identified a molecule named lncRSFD, which is highly expressed in sheep adipose tissues. The lncRSFD gene generates two distinct transcript variants via alternative splicing: lncRSFD‐L and lncRSFD‐S. Functionally, lncRSFD alternative splicing (lncRSFD‐L/S) promotes the proliferation, differentiation, and lipid metabolism of adipocytes ...

Mineral status of California beef cattle. [PDF]

Translational animal science, 2018
Optimal mineral nutrition is required for cattle reproduction, immune function, and structural development. Formal evaluation of the current mineral status of California beef cattle is currently lacking. In 2017, a survey was initiated that evaluated a panel of 10 different minerals in 14 counties across California.

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Aflatoxin Toxicity in Beef Cattle

Experimental Biology and Medicine, 1968
ConclusionsUnder simulated practical conditions, graded levels of aflatoxin fortified cottonseed meal were fed to young beef cattle. The levels of aflatoxin B1 fed in the ration to groups of 10 steers for 133-196 days were 0, 100, 300, 700, and 1000 parts per billion (ppb). Significant growth inhibition, decreased feed efficiencies, and increased liver
