The effect of calpastatin polymorphism and its interaction with RYR1 genotypes on carcass and meat quality of crossbred pigs

Agricultural and Food Science, 2008
The aim of the study was to establish the relationship between a calpastatin gene (CAST) polymorphism, the ryanodine receptor gene (RYR1) polymorphism and carcass/meat quality traits in crossbred pigs. No significant differences in the analyzed pigs were

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

Ethology, EarlyView.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Effects of a feeding strategy to increase intramuscular fat content of pork under the conditions of organic farming [PDF]

, 2007
In an ongoing study, the effect of the implementation of a specific feeding strategy using a high portion of home-grown grain legumes on the intramuscular fat (IMF) content of pork, is assessed under different conditions on organic farms in Germany and ...

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Estimating the Economic Value of Specific Characteristics Associated with Angus Bulls Sold at Auction [PDF]

The genetic traits of a purebred bull convey the reproductive and economic value to buyers. This study examines and compares the value of actual production weights (birth, weaning, and yearling weight), production expected progeny differences (EPDs ...

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 ...
