Behavioural response to a chronic intermittent social stressor is increased in entire male compared to castrated male pigs

, 2018
Entire male pigs show more agonistic and sexual behaviour, which might negatively affect welfare in group-housed entire male fattening pigs. In order to assess chronic stress in entire and castrated male pigs, we conducted an experiment with a 2×2×2 ...

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

A biomimetic ducted nipple reveals gestational age‐dependent deficits in suction generation in a neonatal pig model

The Anatomical Record, EarlyView.
Abstract All infant mammals must suckle in order to effectively acquire milk from a nipple. Yet, not all infants are able to do so. Preterm infants in particular face significant feeding challenges, often failing to establish successful breastfeeding due to complex neurophysiologic challenges.

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Animal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

Animal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

Establishment of Humanized EFNB2/B3 Murine Models for Investigating Nipah Virus Pathogenesis

Animal Research and One Health, EarlyView.
ABSTRACT Nipah virus (NiV) is a zoonotic paramyxovirus classified as a WHO priority pathogen, which causes severe respiratory disease and encephalitis in humans with high mortality. Currently, no licensed vaccines or specific antiviral therapies are available.

Effects of an Organic Acid Blend on Growth Performance, Redox Homeostasis, and Intestinal Microbiota of Broilers in an Antibiotic‐Free Production System Under Winter Environmental Challenges

Animal Research and One Health, EarlyView.
Schematic summary of the effects of organic acids on growth performance and gut health‐related parameters in broilers. ABSTRACT This study was conducted to evaluate the effects of an organic acid blend on growth performance, redox homeostasis, and intestinal microbiota of broilers raised in an antibiotic‐free system during the winter season in China ...
