Modelling livestock infectious disease control policy under differing social perspectives on vaccination behaviour.

PLoS Comput Biol 2022 07 14;18(7):e1010235. Epub 2022 Jul 14.

The Zeeman Institute for Systems Biology and Infectious Disease Epidemiology Research, School of Life Sciences and Mathematics Institute, University of Warwick, Coventry, United Kingdom.

The spread of infection amongst livestock depends not only on the traits of the pathogen and the livestock themselves, but also on the veterinary health behaviours of farmers and how this impacts their implementation of disease control measures. Controls that are costly may make it beneficial for individuals to rely on the protection offered by others, though that may be sub-optimal for the population. Failing to account for socio-behavioural properties may produce a substantial layer of bias in infectious disease models. Read More

Field Comparison of Removed Substrate Sampling and Emergence Traps for Estimating Culicoides Orbivirus Vectors in Northern Florida.

J Med Entomol 2022 Jul 8. Epub 2022 Jul 8.

University of Florida IFAS, Florida Medical Entomology Laboratory, 200 9th Street SE, Vero Beach, FL 32962, USA.

The larval ecology of Culicoides (Diptera: Ceratopogonidae) influences their spatial distributions and the pathogens they transmit. These features are of special concern for deer farmers in Florida where epizootic hemorrhagic disease virus (EHDV) is a major source of mortality in captive herds. Rarity of larval morphological expertise leads many researchers to study larval ecology by quantifying emergence, either with field emergence traps or removing substrate from the field for observation under laboratory conditions.

Understanding the contribution of soybean crop residues inoculated with Bradyrhizobium spp. and not harvested on nitrogen supply in off-season corn cultivars.

PLoS One 2022 22;17(6):e0269799. Epub 2022 Jun 22.

Department of Biology, Laboratory for Molecular Plant Physiology and Biotechnology, University of Antwerp, Antwerpen, Belgium.

Excessive rainfall in the soybean preharvest period can make mechanized crop harvesting technically and economically unfeasible, causing 100% losses in soybean grain yield. An alternative to reduce the economic losses of farmers would be using unharvested soybean crop residues as a source of nitrogen (N) for the subsequent corn crop. However, a question that still needs to be understood is whether the amount of N released from unharvested soybean residues (straw and grains) is sufficient to meet all the nutritional demand for this nutrient in the off-season corn.

Growth rates of contract-reared versus home-reared replacement dairy heifers.

Animal 2022 Jul 17;16(7):100570. Epub 2022 Jun 17.

Teagasc, Animal and Bioscience Research Department, Dairy Production Research Centre, Moorepark, Fermoy, Co Cork P61P302, Ireland. Electronic address:

Successful heifer rearing is dependent on achieving optimal average daily gain (ADG) targets to calve for the first time at 24 months. Whilst dairy farmers internationally have traditionally managed their heifers on-farm to achieve these targets, recent dairy herd expansion within Europe has resulted in increased demand for labour-saving heifer-rearing strategies, such as off-farm contractrearing. However, loss of direct influence on the day-to-day management decisions affecting the ability of heifers to grow adequately to achieve this age of first calving may represent a potential barrier to uptake.
