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

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
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 ...

Application of Genomic Random Regression Models for Genetic Parameter Estimations of Female Fertility Traits in Different Parities in German Holsteins

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of the present study was to infer genetic (co) variance components and to estimate parity‐specific breeding values for the female fertility traits non‐return rate after 56 days, the interval from calving to first service and days open by applying random regression models on a time‐dependent parity scale. In this regard, we considered a

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

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
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 ...

First Detection of Lactococcus formosensis subsp. formosensis in Rainbow Trout (Oncorhynchus mykiss) in Europe

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis are etiological agents of piscine lactococcosis, a disease reported in Italy since the early 1990s and linked to significant aquaculture losses. To the best of our knowledge, this study reports the first detection of L. formosensis subsp. formosensis in farmed rainbow trout (

Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsia salmonis , the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.
