Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

Veterinary Record, Volume 199, Issue 6, Page e298-e303, 19/26 September 2026.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...

A Diverse Pasture Grazing System Enhances Ewe and Lamb Performance Over a Three‐Year Grazing Study

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT High‐output pasture‐based ruminant production systems in temperate regions are typically based on perennial ryegrass (Lolium perenne L.; PRG) swards. Multispecies swards can improve animal performance; however, evidence from multi‐year, full‐system experiments remain limited.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 602-612, July 2026.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Targeting Myostatin for Sustainable Meat Production: Insights From Multiple Species

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Myostatin gene (MSTN), a TGF‐β superfamily member, negatively regulates skeletal muscle growth, positioning it as a prime genetic target for enhancing livestock meat production. This review synthesizes evidence from 1979 to 2025 on MSTN mutations across cattle, pigs, poultry, sheep, goats, and rabbits, emphasising impacts on yield, quality ...

Genetic effects on coat colour in cattle: dilution of eumelanin and phaeomelanin pigments in an F2-Backcross Charolais × Holstein population

BMC Genetics, 2007
Background In cattle, the gene coding for the melanocortin receptor 1 (MC1R) is known to be the main regulator of the switch between the two coat colour pigments: eumelanin (black pigment) and phaeomelanin (red pigment).
