Risk factors related to resistance to Rhipicephalus (Boophilus) microplus and weight gain of heifers

Semina: Ciências Agrárias, 2015
The aim of the present study was to evaluate the influence of age and genetics in dairy heifers on resistance to the cattle tick Rhipicephalus (Boophilus) microplus and correlate these parameters with weight gain.

The use of Diathermic Syncope® for stunning cattle

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The EFSA Panel on Animal Health and Welfare (AHAW) was asked to deliver a scientific opinion on the use of Diathermic Syncope® (DTS) for stunning cattle. A dossier was provided by the applicant as the basis for an assessment of the extent to which the method is able to provide a level of animal welfare at least equivalent to that ensured by ...

Genome‐Wide Association Study (GWAS) for Linear Body Measurements of Sussex Cattle (Bos taurus) at Weaning and Yearling Age in South Africa

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
These results show that GWAS can be a useful tool for recognising novel loci and unravelling the genetic basis of complex economic traits. Sussex cattle exhibited candidate genes (RAB31, BIRC5, TEX22, CFAP100 and LOC617705) as potential candidate genes for linear body measurement traits, which could serve as significant marker information for genome ...

Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 79-91, January 2026.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to

Impact of FSH‐Induced Ovarian Stimulation on Oocyte Recovery and In Vitro Embryo Production in the Red Sindhi Cows

Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.
ABSTRACT Follicle‐stimulating hormone (FSH) plays an important role in regulating reproductive events, particularly follicular development and oocyte competence acquisition. Some studies using FSH protocols in zebu cattle were performed, but data regarding its application in the Red Sindhi breed are scarce and therefore warranted. In this context, this

Epigenetic Modifications Influence Reproductive Traits in Small Ruminants

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
The epigenome undergoes dynamic changes shaped by the intricate interplay of genetic and environmental factors, which are crucial for individual growth and development. Recent studies suggest that factors such as nutrition, thermal stress (TS), infections, and assisted reproductive technologies (ARTs) can influence epigenetic changes in small ruminants

Lethality of Beef Cooking Methods Against Pediococcus Species Surrogates of Shiga Toxin‐Producing Escherichia coli

Journal of Food Safety, Volume 45, Issue 6, December 2025.
High‐temperature long‐time cooking methods, favored for enhancing the palatability of beef, are hypothesized to account for low incidences of meat‐borne STEC outbreaks in Kenya. The study demonstrated the lethality of boiling, simmering, and roasting over pan‐broiled beef burger patties that are predominantly implicated in foodborne STEC outbreaks in ...
