Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The effects of harvest weights on composition, amino acid (AA) digestibility and metabolizable energy (MEN) of Tenebrio molitor (TM) were investigated using cecectomized laying hens. The partially defatted and dried TM variants comprised median individual frass‐free harvest weights of 60, 80, 100, and 120 mg of larvae, and a pupae ...

Legehennefutter mit 100% Öko-Komponenten [PDF]
, 2005 EC Regulation 1804/99 requires organic sources of all components of feed in organic husbandry. Especially for organic pig and poultry nutrition it is not researched which components ensure the supply of amino acids. In our previous studies in 2003 with

The Journal of Wildlife Management, EarlyView.We found that urban wild turkey had a higher probability of occupying a site if it was farther from roads and trails, closer to water, had more available habitat at finer spatial scales, or had lower mean tree height at larger spatial scales Abstract Once extirpated from most of its range because of overharvest and habitat loss in the early 1900s, the ...

Determination of Minimum Horizontal Distance between Laying-Hen Perches [PDF]
, 2014 The objective of the study was to determine minimum horizontal distance (HD) between perches for laying hens using qualitative and quantitative behavioral analysis. A real-time monitoring system was developed to record hen’s perching behaviors, such as

Continuous‐Wave (CW) Photo‐CIDNP NMR Spectroscopy: A Tutorial
Magnetic Resonance in Chemistry, EarlyView.ABSTRACT Photo‐chemically induced dynamic nuclear polarisation (photo‐CIDNP) is a nuclear spin‐selective magnetic resonance phenomenon that has traditionally been used to mechanistically study chemical reactions involving the (transient) formation of radical molecular species, extract EPR observables of short‐lived radicals, probe biomolecular ...

Auf die Auslaufbepflanzung gerichtetes Verhalten von Legehennen bei unterschiedlicher botanischer Zusammensetzung und Bodendeckung der Grasnarbe [PDF]
, 2013 In organic laying hens husbandry it is desirable that the animals cover a proportion of their daily fodder intake by foraging in the outside run, e.g. by grazing.

DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery
Remote Sensing in Ecology and Conservation, EarlyView.Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...

The Isoleucine Requirement of the Laying Hen
Poultry Science, 1954 Abstract WHILE the requirements of the chick for the essential amino acids are known to a considerable extent those of the laying hen have been established only for trytophan, lysine, methionine and cystine (Ingram et al., 1951a, b) and leucine (Cravens, 1948).
