Carcass and internal organ weights in semi-domesticated reindeer

Rangifer, 1990
Estimates of the mass of the different organs and tissues within organisms have been used in many ecological and physiological studies. Weight gain of reindeer foetuses is most rapid during the last trimester of gestation (see Roine et al. 1982). The developing reindeer foetus shows a well-advanced circulatory system at an age of 5 months.

What's the price of meat? Sources of variation in retail meat price data and impacts on market performance analysis

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Retail meat price data, an essential element of market analysis, can differ substantially across data sources. Volume‐weighted retail meat prices calculated using scanner data are lower than Bureau of Labor Statistics (BLS) prices. Generally, the difference between BLS prices and scanner‐based prices increases as the volume sold increases and ...

RECEITA DOS CORTES SECUNDÁRIOS DA CARCAÇA DE MACHOS NELORE NÃO CASTRADOS ABATIDOS COM DIFERENTES PESOS E DENTIÇÕES

Ciência Animal Brasileira, 2013
The objective of this work was to assess the income of deboning secondary cuts from non-castrated Nellore carcasses, slaughtered with different weights and dentition. Fourty animals with average initial weight at feedlot of 350 kg were used.

Recently Evolved, Stage‐Specific Genes Are Enriched at Life‐Stage Transitions in Flies

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
We discovered that 20%–30% of protein‐coding genes in Drosophila melanogaster and Aedes aegypti are only expressed during specific stages of development. Surprisingly, many of these stage‐specific genes are newly evolved, unique to flies and mosquitoes, shedding light on how insect development has evolved over time.

Carcass characteristics and body components of Santa Inês lambs in feedlot fed on different levels of forage cactus meal

Revista Brasileira de Zootecnia, 2011
The objective of this study was to evaluate the effect of the replacement of a ground corn diet by a forage cactus meal diet on the carcass characteristics and body components of Santa Inês lambs finished in feedlot. This study was carried out at Estação

Insects as sustainable source of feed for poultry

JSFA reports, EarlyView.
Abstract Production of animal feed in an environmentally effective way is the key point for the development of sustainable agriculture. The livestock farming industry is increasing globally to meet the demand for animal protein, resulting in higher food–feed competition while rationing animal diets. In addition, it creates increased pressure on natural

The wildlife strikes back: determining the secondary strike risk associated with a mammal–aircraft collision

The Journal of Wildlife Management, EarlyView.
Wildlife‐aircraft collisions are a growing concern. This study at Dublin Airport investigated the secondary strike risk posed by scavengers using simulated hare‐strike events. Results showed that birds, especially hooded crows, detected carcasses faster than mammals, supporting the effectiveness of current rapid clean‐up protocols in minimizing ...

Prediction of the meat content of the carcass and valuable carcass parts in French lop rabbits using some traits measured in vivo and post mortem

Czech Journal of Animal Science, 2006
The experiment was performed on 60 French lop rabbits raised under extensive conditions and sacrificed at body weight of about 3 kg. It was found that the best indicators of meat weight (g) in rabbit carcasses were body weight, head width and lower thigh

Seasonally migrating zooplankton strongly enhance Southern Ocean carbon sequestration

Limnology and Oceanography, EarlyView.
Abstract High‐latitude zooplankton can sequester millions of tons of carbon due to their seasonal migration from the surface ocean to depth, and their respiration and mortality during overwintering. This seasonal vertical migration pump (SVMP) efficiently removes carbon but not limiting nutrients such as iron from the surface layers.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
