Randomised, Double‐Blinded, Placebo‐Controlled Challenge Test With Single Food Items in Dogs With Atopic Dermatitis and Adverse Food Reactions

Veterinary Dermatology, EarlyView.
ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

Effects of bio‐slurry and inorganic nitrogen fertilizer rates on wheat yield components, yield, and soil properties

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Maintaining soil fertility and enhancing food production on smallholder farms in Ethiopia remain a major challenge due to severe nutrient depletion caused by continuous cropping with minimal external nutrient inputs. In this context, a field study was conducted on Nitisols over two consecutive cropping seasons (2022–2023) across four locations

Sustained contraceptive‐level plasma concentrations of 4,4′‐dinitrocarbanilide in free‐ranging urban feral pigeons fed a custom bait Niveles plasmáticos altos y sostenidos de 4,4′‐dinitrocarbanilida en palomas domésticas libres alimentadas con un cebo anticonceptivo

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised

Improving Genomic Prediction Using High‐Dimensional Secondary Phenotypes: The Genetic Latent Factor Approach

Biometrical Journal, Volume 67, Issue 5, October 2025.
ABSTRACT Decreasing costs and new technologies have led to an increase in the amount of data available to plant breeding programs. High‐throughput phenotyping (HTP) platforms routinely generate high‐dimensional datasets of secondary features that may be used to improve genomic prediction accuracy.
