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 ...

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

Fatty Acid Interconversion by Laying Hens
Poultry Science, 1966 Abstract FEIGENBAUM and Fisher (1959) demonstrated that the degree of saturation of body fat could be influenced by the ingestion of both saturated and unsaturated fatty acids. Egg fat saturation could be influenced only by the ingestion of unsaturated fatty acids.

Dietary Phosphorus Needs of Laying Hens
Poultry Science, 1977 Abstract Two experiments were conducted with commercial strain, White Leghorn laying hens, kept in wire cages, to determine the effect of low dietary phosphorus (P) levels on production characteristics. In experiment 1, rations that contained 0.19, 0.28 or 0.37% available P (AP) were fed to 22 week old hens.

Interactions between Behaviour and Genetics in Wild and Domestic Bird Populations [PDF]
Personality traits can be favoured by both natural and artificial selection, if they result in increased fitness or productivity, and therefore play an important role in both wild and domestic populations.

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 ...

Behavioural and physiological responses of laying hens to automated monitoring equipment [PDF]
, 2018 Automated monitoring of behaviour can offer a wealth of information in circumstances where observing behaviour is difficult or time consuming. However, this often requires attaching monitoring devices to the animal which can alter behaviour, potentially ...

Spatial and temporal variation in survival of female wild turkeys
The Journal of Wildlife Management, EarlyView.We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.
