Providing ramps in rearing aviaries affects laying pullet distribution, behavior and bone properties
Publikováno v:
Journal of Applied Poultry Research, Vol 31, Iss 4, Pp 100283- (2022)
SUMMARY: To ensure that laying hens can make full use of the various resources within an aviary barn and develop optimum bone health while minimizing keel bone fractures, appropriate cognitive and bone development during rearing is critical. Given pr

Summary: Fractures to the keel bone is one of the greatest problems facing the laying hen industry. With most severe effects observed in non-cage housing, frequencies are expected to dramatically increase as the industry continues transitioning away

European farms for broiler breeders often have raised slatted areas in front of the nests, but in other regions of the world no raised slatted areas are provided. This study aimed to investigate the effects of a raised slatted area on leg health, mat

In a 2×2 factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietary calcium (Ca) to phosphorus (P) ratio in phytase

Epitaxial, textured Ru 2 Si 3 films were grown by the template technique, a special molecular beam epitaxy method, on Si(111) and Si(001). Epitaxial relationships of the films with respect to the substrate were determined by X-ray diffraction. Two co

Recent band structure calculations indicate, that ruthenium silicide (Ru2Si3) is semiconducting with a direct band gap. Electrical measurements lead to a band gap around 0.8 eV which is technologically important for fiber communications. This makes R

The carbon doping behavior of trimethylarsenic (TMAs) in low-pressure metalorganic vapor phase epitaxy (LP-MOVPE) of GaAs was studied in the temperature range of 550 to 700°C and at various trimethylarsenic/trimethylgallium (TMAs/TMGa) ratios using
