Effect of weaning on some plasma metabolites in buffalo calves fed diets with or without supplemental chromium picolinate

open access: yesItalian Journal of Animal Science, 2010
The objective of this study were 2 fold: to determine whether the weaning (abrupt transition from liquid to solid diet) at the age of 90 days causes stress in buffalo calves, and if so, to alleviate the negative effect of stress by chromium picolinate ...

Fecal cortisol metabolites reflect transport stress in 3-month-old dairy calves pre- and postweaning: A pilot study

open access: yesJournal of Dairy Science, 2023
: Measurement of fecal cortisol metabolites (FGCM) is a well-established, noninvasive method to assess stress in adult dairy cattle. However, this procedure has not yet been validated for unweaned dairy calves, and it can be expected that the milk ...

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

Early life diet conditions the molecular response to post-weaning protein restriction in the mouse

open access: yesBMC Biology, 2018
Background Environmental influences fluctuate throughout the life course of an organism. It is therefore important to understand how the timing of exposure impacts molecular responses.

Age at weaning and the endocrine response to stress

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2003
Seventy-five Angus x MARC II crossbred heifers were used to assess the effects of age at weaning on calf performance and blood constituents. Calves were weaned at 150, 210, or 270 days of age with comparisons made to their non-weaned counterparts. Changes in blood chemistry and hematology (cortisol, glucose, T3, total proteins, packed cell volume and ...

Evaluation of therapeutic effects of D‐limonene following orchiopexy in the rat model of cryptorchidism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
D‐limonene supplementation enhances testicular recovery following orchiopexy in a rat model of bilateral cryptorchidism. Treatment with D‐limonene reduces oxidative stress (↓MDA, ↑SOD, ↑GPx, ↑TAC), downregulates pro‐apoptotic proteins (↓TNF‐α, ↓BAX, ↓Caspase‐3), and upregulates anti‐apoptotic Bcl‐2 expression.

Weaning Induces Stress-Dependent DNA Methylation and Transcriptional Changes in Piglet PBMCs

open access: yesFrontiers in Genetics, 2021
Changes to the epigenome, including those to DNA methylation, have been proposed as mechanisms by which stress can induce long-term physiological changes in livestock species. Pig weaning is associated with dietary and social stress, both of which elicit

Developing a strain‐dependent susceptibility to hepatocellular carcinoma in a murine model based on histopathological evidence and genetic context

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Using F1 (C57BL/6J/Smad4+/− X CC) mice, we found that partial loss of Smad4 promotes liver carcinogenesis in a strain‐dependent manner, highlighting the importance of genetic modifiers in tumor susceptibility. The use of Collaborative Cross mice provides a valuable platform for uncovering genotype‐specific cancer susceptibilities in preclinical ...

Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

open access: yesThe Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...
