Equipment and methods for poultry euthanasia by a single operator
(2020-12)Euthanasia of large poultry can be particularly challenging due to the difficulty of manual cervical dislocation of large older birds. Euthanasia is intended to swiftly render the animal unconscious and rapidly lead to ... -
Differentiating Vaccine-Related Fowl Cholera from Naturally Occurring Disease
(2020-12)Vaccine-related fowl cholera must be considered when flock mortality increases after use of a live Pasteurella multocida vaccine product. All registered live vaccines serotype as Heddleston 3,4; however, in some regions ... -
Intermittent Bolus Feeding Enhances Organ Growth More Than Continuous Feeding in a Neonatal Piglet Model
(2021-01)Background: Orogastric tube feeding is frequently prescribed for neonates who cannot ingest food normally. In a piglet model of the neonate, greater skeletal muscle growth is sustained by upregulation of translation ... -
Extraembryonic Endoderm (XEN) Cells Capable of Contributing to Embryonic Chimeras Established from Pig Embryos
(2021-01-12)Most of our current knowledge regarding early lineage specification and embryo-derived stem cells comes from studies in rodent models. However, key gaps remain in our understanding of these developmental processes from ... -
Centennial Review: The chicken yolk sac is a multifunctional organ
(Elsevier, 2020-12-08)The yolk sac (YS) consists of the yolk, which supplies nutrients, and the YS tissue, which surrounds the yolk and provides essential metabolic functions for the developing embryo. The YS tissue is derived from the midgut ... -
Investigating the Impact of Brief Outings on the Welfare of Dogs Living in US Shelters
(MDPI, 2021-02-19)Social isolation likely contributes to reduced welfare for shelter-living dogs. Several studies have established that time out of the kennel with a person can improve dogs’ behavior and reduce physiological measures of ... -
Transcriptome Response of Liver and Muscle in Heat-Stressed Laying Hens
(MDPI, 2021-02-10)Exposure to high ambient temperature has detrimental effects on poultry welfare and production. Although changes in gene expression due to heat exposure have been well described for broiler chickens, knowledge of the effects ... -
Chronic stress and adipose tissue in the anorexic state: endocrine and epigenetic mechanisms
(Taylor & Francis, 2020)Although adipose tissue metabolism in obesity has been widely studied, there is limited research on the anorexic state, where the endocrine system is disrupted by reduced adipose tissue mass and there are depot-specific ... -
GCA: an R package for genetic connectedness analysis using pedigree and genomic data
(2021-02-15)Background Genetic connectedness is a critical component of genetic evaluation as it assesses the comparability of predicted genetic values across units. Genetic connectedness also plays an essential role ... -
Graduate Student Literature Review: Potential mechanisms of interaction between bacteria and the reproductive tract of dairy cattle
(2020-11)Although the presence of bacteria has been characterized throughout the reproductive tracts of multiple species, how these bacteria may interact with the host has yet to be described. Previous reviews have described how ... -
An assessment of genomic connectedness measures in Nellore cattle
(2020-11)An important criterion to consider in genetic evaluations is the extent of genetic connectedness across management units (MU), especially if they differ in their genetic mean. Reliable comparisons of genetic values across ... -
Rewiring of gene expression in circulating white blood cells is associated with pregnancy outcome in heifers (Bos taurus)
(2020-10-08)Infertility is a challenging phenomenon in cattle that reduces the sustainability of beef production worldwide. Here, we tested the hypothesis that gene expression profiles of protein-coding genes expressed in peripheral ... -
Delayed access to feed affects broiler small intestinal morphology and goblet cell ontogeny
(2020-11)Broilers are often deprived of feed and water for up to 48 h after hatch. This delayed access to feed (DAF) can inhibit small intestine development. The objective of this study was to determine the effects of DAF on small ... -
Heat Stress Reduces Metabolic Rate While Increasing Respiratory Exchange Ratio in Growing Pigs
(MDPI, 2021-01-17)Heat stress (HS) diminishes animal production, reducing muscle growth and increasing adiposity, especially in swine. Excess heat creates a metabolic phenotype with limited lipid oxidation that relies on aerobic and anaerobic ... -
Interleukin-6 promotes primitive endoderm development in bovine blastocysts
(2021-01-12)Background Interleukin-6 (IL6) was recently identified as an embryotrophic factor in bovine embryos, where it acts primarily to mediate inner cell mass (ICM) size. This work explored whether IL6 affects ... -
Genome-wide association study to identify genetic loci associated with gastrointestinal nematode resistance in Katahdin sheep
(2020-01-03)Resistance to gastrointestinal nematodes has previously been shown to be a moderately heritable trait in some breeds of sheep, but the mechanisms of resistance are not well understood. Selection for resistance currently ... -
Broiler Chicken Welfare during Pre-Slaughter Transport

Minor procedural variations affect canine behavior during sociability assessments
(2020-08)A growing number of studies make claims about canine sociability in both applied and basic contexts. Yet, there is currently no standard for measuring sociability in dogs. The purpose of this two-part study was to determine ... -
Mutations Upstream of the TBX5 and PITX1 Transcription Factor Genes Are Associated with Feathered Legs in the Domestic Chicken
(2020-09)Feathered leg is a trait in domestic chickens that has undergone intense selection by fancy breeders. Previous studies have shown that two major loci controlling feathered leg are located on chromosomes 13 and 15. Here, ...
