Genetic associations between reproductive and linear-type traits of Holstein cows in Brazil

Revista Brasileira de Zootecnia
This study aimed to estimate heritability, genetic, and residual correlations between reproductive traits such as age at first calving, calving interval, dry period, and first service period and linear type traits measured in Holstein cows born between ...

Genetic Associations of Functional Longevity With Sexual Precocity and Growth Traits in Nellore Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Functional longevity (FL) is a complex trait that integrates many attributes directly contributing to the successful retention and productivity of a cow within the herd. Consequently, improving FL in beef cattle increases herd profitability. This study aimed to estimate the genetic associations between two alternative FL definitions and traits

Genetic Evaluation for Functional Longevity in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Stayability (STAY) presents limitations in capturing genetic variability among animals with varying calving records up to 76 months of age. Furthermore, because STAY is measured late in life (typically at 6 years of age), it inherently prolongs generation intervals.

The variability of giraffe skull morphology

Journal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Psychophysical changes after total sleep deprivation and experimental muscle pain

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep disturbances exacerbate chronic pain, increase psychological load, and increase inflammation. Delayed onset muscle soreness (DOMS) mimics aspects of chronic pain, predominantly affecting peripheral pain mechanisms, while experimental sleep provocations have been shown to impact central pain mechanisms.
