Production and economic traits of purebreed and crossbred animals in diary herds of mountain areas [PDF]

, 2013
Beef production from dairy herds represents an alternative source to improve the farm profitability. The use of beef semen to mate cattle not destined to breed replacement represent an interesting source of income for dairy farmers particularly due to ...

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

Investigation on carcass composition and meat yield characteristics of domestic geese carcass

Eurasian Journal of Veterinary Sciences
It was aimed to determine quantities of meat, bone and skin of goose carcass. For this purpose, totaly 33 geese, 15 of which male and 16 of which female, were used. It was determined that carcass consisted of 54-58% meat, 18-22% bone and 24.28% skin. Thigh had the highest meat ratio (61.91%) and neck had the highest skin ratio (39,24%) among different ...

Influence of Increasing Carcass Weights on Pork Carcass Characteristics and Traditional and Alternative Fabrication Yields

Meat and Muscle Biology
The objective was to characterize the effects of increasing carcass weight on pork carcass characteristics and yields from traditional and alternative fabrication methods, as well as evaluate the size of novel retail cuts. Pigs (n = 85) were slaughtered and divided into 3 hot carcass weight (HCW) categories: Average (99 to 109 kg), Heavy (116 to 126 kg)

Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

Oikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Research note: differential heterosis of spent laying hens’ carcass characteristics and meat quality in reciprocal crosses between White Leghorn and Beijing-You chickens

Poultry Science
: Hybridization is used extensively in commercial layer production. However, heterosis for carcass performance and meat quality of spent laying hens remains unclear, especially under the trend of extended laying cycles.

The integrated reproductive response: the scope for seasonal phenotypic flexibility shapes reproductive outcomes across fish populations

Oikos, EarlyView.
Across north‐temperate environments, rapid environmental change has disrupted the seasonal life histories of resident organisms, decreasing the reliability of environmental cues. Flexible responses capable of buffering the effects of unpredictable environmental variation to defend performance and reproductive outcomes may thus be key to species‐ and ...

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

Oikos, EarlyView.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

Oikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...
