A uterine‐centric view of reproductive senescence: Genetic insights into late‐life performance in laying hens

iMetaOmics, EarlyView.
This study identifies uterus weight as a heritable (h2 = 0.45) intermediate phenotype that independently associates with late‐life egg production and eggshell quality in aged laying hens. Genome‐wide association study (GWAS) reveals a genome‐wide significant locus on chromosome 3 and suggestive loci on chromosome 11 for uterus weight, mediation ...

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

Journal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Maintaining egg freshness in the absence of refrigeration: The potential of zero‐energy cooling pots

JSFA reports, EarlyView.
Abstract Background Egg storage in regions with unreliable electricity is challenging, leading to rapid quality deterioration and postharvest losses. This study evaluated the efficacy of a Zero‐Energy Cooling (ZEC) pot, an evaporative cooling technology, for preserving table egg quality in comparison to conventional refrigeration and ambient storage ...

Genetic analysis of production, immunity and behaviour in laying hens [PDF]

, 2010
The new regulations about the husbandry of laying hens and the so-called genomic revolution offer both opportunities and challenges for the breeding of layers. Hens are currently housed mainly in battery cages of 4 individuals each.

Separation of trichothecene mycotoxins in a matrix of hemp (Cannabis sativa L.) seed, and quantification of deoxynivalenol in hemp grain infected with Fusarium graminearum

JSFA reports, EarlyView.
Abstract Background Fusarium graminearum, one of the causal agents of ear rot in maize and head blight of cereal grains, also infects hemp (Cannabis sativa L. containing a maximum of 0.3% tetrahydrocannabinol or THC). This fungal pathogen produces trichothecene mycotoxins when it infects maize and cereal grains, but little is known about its production

Crude glycerin in co-composting with laying hen manure reduces N losses

Scientia Agricola
: The composting of laying hen manure is an efficient way of treating waste and producing an organic fertilizer with excellent characteristics; however, the high N losses reduce its concentration in the resulting fertilizer. Associating this residue with

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Home range shifts and habitat selection across life‐history stages in grey partridges

Wildlife Biology, EarlyView.
Understanding how birds use space throughout the year is essential for effective conservation planning, even in resident species. We investigated seasonal space use in a Central European population of grey partridges Perdix perdix, a rapidly declining residential farmland bird.
