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 Parameters for Novel Feedlot Profitability‐Related Traits in Nelore Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 411-421, May 2026.
ABSTRACT This study aimed to estimate (co)variance components and genetic parameters for accumulated profitability (AFP) and profit per kilogram of liveweight gain (PFT), and their relationships with weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at first calving (AFC), probability of precocious calving at 30 ...

No evidence for a recent genetic bottleneck in the endangered Sheko cattle breed (African Bos taurus) revealed by microsatellite analysis [PDF]

, 2009
Sheko is African taurine cattle, valued for its milk yield, adaptation to humid tsetse infested environment and trypanotolerance. We used 30 microsatellite markers in analyzing 30 DNA samples. We found high genetic diversity and no genetic bottlenecks in

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 431-442, May 2026.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Genomic Prediction Ability Using Linear and Threshold Approaches for Different Stayability Definitions in Nellore Females

Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 457-464, May 2026.
ABSTRACT Enhancing female longevity through regular calvings improves herd replacement rates and reduces the costs associated with replacing low reproductive efficiency animals. Stayability (STAY), defined as a cow's ability to remain productive in the herd, is a categorical trait that challenges traditional genetic evaluation due to its non‐normal ...

Zooprophylaxis as a control strategy for malaria caused by the vector Anopheles arabiensis (Diptera: Culicidae) : a systematic review [PDF]

, 2017
Background: Zooprophylaxis is the use of wild or domestic animals, which are not the reservoir host of a given disease, to divert the blood-seeking malaria vectors from human hosts.
