Agonic Aspiration of Blood: Not Useful as an Animal-Based Indicator of Electrical Stunning Ineffectiveness in Pigs (Sus scrofa domesticus)
(MDPI, 2023-07-13)
Agonic aspiration of blood (AAB) may result from an inadequate exsanguination with accidental trachea severing, that can be favoured by ineffective stunning of pigs (Sus scrofa domesticus). This study ...
The equipment used in the SF6 technique to estimate methane emissions has no major effect on dairy cow behavior
(Frontiers Media, 2021-01-29)
The natural behavior of animals can be disrupted by the techniques and materials of research methodologies. This study aimed to evaluate the effect of the equipment used in the SF6 tracer technique to ...
Hierarchical clustering as a tool to develop a classification scheme for rabbit meat quality
(World Rabbit Science Association (WRSA), 2021-09-01)
This study aimed to characterise the quality of meat from commercially-raised rabbits. Animals came from five different producers and were laughtered in three different plants under provincial or federal ...
Novel strategies to improve chicken performance and welfare by unveiling host-microbiota interactions through hologenomics
(Frontiers Media, 2022-09-06)
Fast optimisation of farming practices is essential to meet environmental sustainability challenges. Hologenomics, the joint study of the genomic features of animals and the microbial communities ...
Disentangling the causal relationship between rabbit growth and cecal microbiota through structural equation models
(BMC, 2022-12-19)
Background
The effect of the cecal microbiome on growth of rabbits that were fed under different regimes has been studied previously. However, the term “effect” carries a causal meaning that can be ...
Hierarchy Establishment in Growing Finishing Pigs: Impacts on Behavior, Growth Performance, and Physiological Parameters
(MDPI, 2023-01-14)
Pigs are social animals that live in groups with well-established social structures and have always been a key species in debates over farm animal welfare. However, intensive production systems often ...
Analysis of the causal structure of traits involved in sow lactation feed efficiency
(BMC, 2022-07-26)
Background
Feed efficiency during lactation involves a set of phenotypic traits that form a complex system, with some traits exerting causal effects on the others. Information regarding such ...
Animal Welfare and Meat Quality Assessment in Gas Stunning during Commercial Slaughter of Pigs Using Hypercapnic-Hypoxia (20% CO2 2% O2) Compared to Acute Hypercapnia (90% CO2 in Air)
(MDPI, 2020-12-20)
Animals must be stunned before slaughter to avoid fear, pain, and distress. In pigs, the most extensively used method is exposure to hypercapnia (high (>80%) concentrations of carbon dioxide (CO2)). ...
Characterization of the Maternally Derived Antibody Immunity against Rhdv-2 after Administration in Breeding Does of an Inactivated Vaccine
(MDPI, 2020-08-28)
Inactivated strain-specific vaccines have been successfully used to control rabbit haemorrhagic disease (RHD) caused by RHDV-2 in the rabbit industry. It is unknown whether and how vaccination of breeding ...
