Handmade Biopsy for Genotyping of In Vitro‐Produced Bovine Embryos

Anatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT Blastocyst biopsy allows genomic selection of pre‐implantation bovine embryos, reducing generation interval and enhancing the genetic gain. We aimed to evaluate the suitability of a simple biopsy procedure, performed by hands, using a splitting microblade and a stereoscope, on in vitro‐produced embryos. Crossbred Bos taurus x B.

Behavioral and demographic effects of open‐pit mining on Central Mountain Caribou in British Columbia

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
The demographic manifestation of mining effects on caribou, a species listed as Vulnerable on the IUCN Red List of Threatened Species, has been disputed. We characterized a cascade of events for caribou associated with open‐pit coal mining beginning with maladaptive behavior responses leading to negative demographic outcomes for the affected caribou ...

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 422-430, May 2026.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

Genetic Parameter Estimation for Plasma Biomarkers Associated With Energy Reserves During Critical Physiological Stages in Sheep

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 443-456, May 2026.
ABSTRACT The ability of ruminants to mobilise and restore body reserves (BR) over time, referred to as BR dynamics, is currently considered an interesting biological component to be included in breeding programs targeting enhanced BR resilience. However, genetic studies of proxies for BR levels and BRD remain scarce, particularly in small ruminants ...

Genetic Parameters of Age at Conception in Nellore Females Using Threshold Models

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 403-410, May 2026.
ABSTRACT Age at conception is a critical factor in the intensification of production systems. It is crucial for intensifying production, optimising reproductive efficiency and boosting Nellore female productivity for genetic progress. However, the low heritability estimates currently limit the effectiveness of selection responses, thereby underscoring ...
