The response of weaned piglets to dietary valine and leucine

open access: yesAnimal, 2017
Valine (Val) is considered to be the fifth-limiting amino acid in a maize-soyabean meal diet for pigs. Excess leucine (Leu) levels often occur in commercial diets, which may attenuate the effect of Val deficiency because of an increased oxidation of Val. The objective of the present experiment was to determine the effect of increasing concentrations of

Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

Factors Influencing Reproductive Performance in Austrian Sow Farms Challenged by Reproductive Disorders

open access: yesVeterinary Sciences
Many piglet-producing farms are facing poor reproductive performance, yet their characteristics remain poorly understood. This study aimed to identify factors contributing to reproductive disorders based on information easily identifiable through an oral

Effect of weaning age on cortisol release in piglets

open access: yesGenetics and Molecular Research, 2016
The effect of weaning age on the adrenal cortex, which plays a vital role in the stress response, is currently unknown. Therefore, plasma adrenocorticotropic hormone (ACTH) and cortisol levels, weights and relative weights of adrenal glands, and steroidogenesis-related protein and enzyme expression levels in piglets weaned on different days were ...

Unraveling piglet gut microbiota dynamics in response to feed additives [PDF]

open access: yes, 2010
Keywords: GI tract, microbiota, pig, PITChip, weaning The gastrointestinal (GI) tract of pigs is colonized by a dense and metabolically active microbiota, comprising mainly bacteria, that have not only a commensal but a symbiotic (beneficial for both ...

Tooth Enamel Carbon and Oxygen Isotope Ratios Reveal Shifts in Neolithic Caprine Husbandry on the Dalmatian Coast, Croatia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Stable isotope analysis of sequential samples of ancient sheep and goat tooth enamel is used to investigate feeding, breeding, and mobility strategies at Neolithic villages on the Dalmatian Coast of Croatia. δ13C values demonstrate clear enrichment of caprine diet in 13C from the Early (c. 8.1–7.5 kya cal.

Porcine circovirus 2 vaccination timing was not associated with piglets’ serological response

open access: yesVeterinary Record, EarlyView.
Abstract Background The development of immunity in pigs starts in utero, but piglets are born immunologically immature and rely on maternal antibodies. Weaning exposes piglets to multiple stressors, yet vaccination is commonly performed around weaning.

Disruption of IgA-mediated aggregation at weaning favors mucus encroachment by commensal bacteria

open access: yesnpj Biofilms and Microbiomes
Disruption of the gut mucus barrier is critical in the development of infectious or chronic inflammatory diseases. The suckling-to-weaning transition is pivotal to the barrier maturation and is associated with a high incidence of gastrointestinal ...

Does pre-weaning mixing and/or object enrichment improve piglet behaviour, welfare, and performance around weaning? [PDF]

open access: yes, 2023
While abrupt weaning is a common practice in commercial swine barns, it subjects piglets to numerous changes at once which is often associated with negative welfare.

Monitoring rodents' life history by body temperature and activity

open access: yesWildlife Biology, EarlyView.
European hamster populations are rapidly declining all over their distribution area. One of the suggested reasons is a strong and ongoing decrease in the reproductive output of about 77% since the nineteen twenties. The cause of this decline is, however, unknown.
