MITOCHONDRIAL DNA POLYMORPHISMS AND FERTILITY IN BEEF CATTLE [PDF]

open access: yes, 2002
Two regions of mitochondrial DNA, D-loop and ND-5 were characterized using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP) involving 422 beef cattle of Hereford and composite breeds from Wokalup’s ...

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Genetic aspects of calving, growth, and carcass traits in beef cattle [PDF]

open access: yes, 2003
The aim of this thesis was to learn more about the genetic background of calving, growth and carcass traits of beef cattle breeds in Sweden, and to assess the possibility of including calving traits and commercial carcass traits in the genetic evaluation.

Comparative grazing behaviour of lactating suckler cows of contrasting genetic merit and genotype [PDF]

open access: yes, 2018
peer-reviewedThe objective of this study was to determine if differences in grazing behaviour exist between lactating suckler cows diverse in genetic merit for the national Irish Replacement index and of two contrasting genotypes.

Better Multi‐Breed Genomic Predictions for Tropical Bull Fertility Using a Breed‐Adjusted Genomic Relationship Matrix

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The pressing requirement for agricultural systems to adopt climate change adaptation strategies specifically designed for tropical environments underscores the significance of implementing sustainable bull breeding practices in beef cattle operations.

Some reports of snowfall from fog during the UK winter of 2008/09 [PDF]

open access: yes, 2009
Snowfall during anticyclonic, non-frontal, and foggy conditions is surprising. Because it is often not forecast, it can present a hazard to transport and modify the surface albedo.

Dissecting the genetic basis of climatic adaptation in wild relatives (Malus baccata) for climate‐resilient apple breeding

open access: yesJournal of Integrative Plant Biology, EarlyView.
This comprehensive map of genetic variation in wild apple (Malus baccata) and set of key genes associated with adaptation to temperature, precipitation, and soil properties establishes a foundation for breeding climate‐resilient apple cultivars and conserving the genetic resources of wild crop relatives.

I could smell there was something wrong with him: Clinical case of a decade of chronic undiagnosed brucellosis

open access: yesClinical Infection in Practice
Background: Brucellosis is a zoonotic infection, typically transmitted by ingestion of unpasteurised dairy products or direct contact with infected animals. It is associated with specific occupations, and travel to endemic countries.

Livestock breeds and Organic farming systems [PDF]

open access: yes, 2007
Organic livestock farming has grown in Wales in recent years. It is focused on producing animals from a predominantly forage-based system, with an emphasis on maintaining animal health through improved welfare and a reduction in the use of routine ...

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

open access: yesNew Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...
