Laying hens in furnished cages [PDF]

, 2003
Concern for the welfare of laying hens housed in conventional cages has led to a change of the Animal Welfare Legislation in Sweden, implying that cages must provide possibilities for hens to lay eggs in a nest, to rest on a perch and to use litter. Such

Effects of stocking density and litter type on litter quality of native chicken

IOP Conference Series: Earth and Environmental Science, 2019
Abstract This study was conducted to identify the effect of stocking density and litter materials on litter quality of Native chicken. Three hundred and twenty-four unsexed native chickens were used for 12 weeks duration of this research.

Establishment of Interspecies Somatic Cell Nuclear Transfer and Transgene‐Free Inducible Pluripotent Stem Cells for Versatile Conservation of the Germplasm Resource of Wild Boar

Animal Research and One Health, EarlyView.
Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

Within-species variation in foliar chemistry influences aquatic leaf litter decomposition [PDF]

, 2007
Leaf-litter inputs provide substrate and energy to stream systems. These contributions vary based on species-specific differences in litter quality, but little is known about how differences in litter quality within a species can affect ecosystem ...

Variability in litter quality and its relationship to litter decay in Canadian forests

Canadian Journal of Botany, 2000
Predicting the effects of climate change on litter decomposition requires an improved understanding of the link between organic composition and the parameters used to define litter quality. Carbon-13 nuclear magnetic resonance spectroscopy with cross-polarization and magic-angle spinning (CPMAS NMR) was used to characterize 36 foliar litters ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.

Species community shifts in fertilized tundra affect decomposition through changes in litter quantity, quality, and the decomposition microenvironment

Arctic Science
As the Arctic warms, soils thaw, decomposition and nutrient mineralization may increase, and deciduous shrubs often grow taller and denser, shifting the competitive environment and affecting soil properties.
