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

Journal 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

Journal 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

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

Journal of Animal Breeding and Genetics, EarlyView.
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 Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...
