Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Estimates of relationship between milk yield and age at first calving in cattle using multivariate REML

, 1993
Relationship between milk yield and age at first calving in cattle were calculated from (co) variances estimated by multivariate restricted maximum likelihood with equal design matrix fitting a unbalanced mixed model with herd, year and calendar month of

Evaluation of Selected Effects on Milk Production and Fertility in Holstein Dairy Cattle

Scientific Papers Animal Science and Biotechnologies, 2023
The breeding of dairy cattle, in terms of investment and operating costs, is the most demanding sector of livestock production. In terms of importance for agricultural enterprises and all of society, in most EU Member States and the Czech Republic it is ...

Estimation of the Genetic Components of (Co)variance and Preliminary Genome-Wide Association Study for Reproductive Efficiency in Retinta Beef Cattle

Animals, 2023
In this study, we analyzed the variation of reproductive efficiency, estimated as the deviation between the optimal and real parity number of females at each stage of the cow’s life, in 12,554 cows belonging to the Retinta Spanish cattle breed, using ...

Exploring the Content Validity of Patient‐Reported Outcome Measures to Capture the Patient Experience of Becker Muscular Dystrophy

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims The patient experience of Becker muscular dystrophy (BMD) is not well understood, making it difficult to evaluate the conceptual relevance of proposed patient‐reported outcome (PRO) measures. This study aimed to conceptualize the patient experience of BMD and evaluate content validity and perceptions of meaningful changes of ...

Identification of genomic regions related to age at first calving and first calving interval in water buffalo using single‐step GBLUP

Reproduction in Domestic Animals, 2020
AbstractIn Brazil, water buffaloes have been used to produce milk for mozzarella cheese production. Consequently, the main selection criterion applied for the buffalo genetic improvement is the estimated mozzarella yield as a function of milk, fat and protein production.

Familiarity and aggression shape long‐term associations and mortality risk in a solitary ungulate

Oikos, EarlyView.
Periodic social interactions are important to animal fitness, even in solitary species. For solitary species, these interactions can be unexpected and shaped by previous encounters. Despite being aggressive and largely solitary, black rhinoceroses Diceros bicornis are commonly seen in groups, suggesting they may engage in more social behaviours than ...

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

People and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.
