Measuring motivation for alfalfa hay in feedlot cattle using voluntary interaction with an aversive stimulus

Typical diets for finishing cattle are concentrate-rich and low in roughage, which may limit species-specific feeding behaviours and increase the risk of digestive disorder. Our objective was to measure how motivated finishing steers are to access alfalfa hay compared with...

Intramuscular alfaxalone with or without buprenorphine or hydromorphone provides sedation with minimal adverse effects in healthy rabbits (Oryctolagus cuniculus) in a randomized blinded controlled trial

OBJECTIVE To evaluate the effects of alfaxalone administered IM with or without buprenorphine or hydromorphone in healthy rabbits (Oryctolagus cuniculus). ANIMALS 24 male rabbits undergoing elective orchiectomy between August 21, 2021, and November 6, 2021. PROCEDURES In this controlled clinical...

Environmental enrichment for pig welfare during transport

This study aimed to assess the effects of environmental enrichment for pigs during transportation in different phases of their productive cycle. Two trials were conducted, the first during transportation of pigs from the piglet production unit (PPU) to the nursery...

What can associations between emotional states and management-based measures teach us about shelter dogs’ welfare? Journal of Veterinary Behavior 69–70, 32–38

It is crucial to understand the effect of living in a shelter on dog's well-being. We hypothesized that mental states may indicate the presence of environmental stressors. The objective of this study was to determine the relationship between specific emotional...

Human perception of cats’ communicative cues: Human‐cat communication goes multimodal

As a central key to apprehend the human-cat relationship, the question of how humans decode the behaviours expressed by their feline companions has drawn scientists' attention in the past decades. To this point, previous studies have not investigated humans' understanding...

Don’t use it? Don’t lose it! Why active use is not required for stimuli, resources or “enrichments” to have welfare value

Current frameworks for designing and evaluating good enclosures and “enrichments” typically focus on animals' active interactions with these features. This has undoubtedly improved the welfare of zoo-housed animals over the last 30 years or more. However, literature reviews from this...

Sedated cesarean sections are associated with increased kid survival compared to general anesthesia in goats: Retrospective cohort of 45 cases (2011–2021)

OBJECTIVE To determine whether anesthesia type (sedation or general anesthesia) affects kid survival to discharge in caprine cesarean sections (C-sections).

Rapid ammonia build-up in small individually ventilated mouse cages cannot be overcome by adjusting the amount of bedding

We sought to investigate if varying levels of bedding had an effect on intra-cage ammonia levels in individually ventilated mouse cages (Euro Standard Types II and III). Employing a routine 2 week cage-changing interval, our goal is to keep ammonia levels...

A novel scoring system for humane endpoints in mice with cecal ligation and puncture-induced sepsis

Animal-based research is essential to the study of sepsis pathophysiology, diagnostics, and therapeutics. However, animal models of sepsis are often associated with high mortality because of the difficulty in predicting imminent death based on premortem assessment of the animals. The...
