Many laying hen producers are transitioning from conventional cages to new housing systems including multi-tier aviaries. Aviary resources, such as litter areas, are intended to encourage hens' expression of natural behaviors to improve their welfare. Little research has examined the influence of laying hen strain on distribution and behavior inside aviaries, yet differences could influence a s...

A cell line from the small brown planthopper (SBPH; Laodelphax striatellus) was established to study replication of rice stripe virus (RSV), a tenuivirus. The SBPH cell line, which had been subcultured through 30 passages, formed monolayers of epithelial-like cells. Inoculation of cultured vector cells with RSV resulted in a persistent infection. During viral infection in the SBPH cell line, th...

Two new species of genus Leporinus from the Araguaia-Tocantins system, Amazon, Brazil, are described. Leporinus unitaeniatus n. sp. is distinguished from the remaining species of this genus by the presence of a conspicuous longitudinal dark brown bar along the lateral line on the flanks, and Leporinus geminis n. sp. is distinguished by an inconspicuous dark bar combined with three large and ver...

The aim of this study was to determine the production performance layer hen strain Hy-Line Brown in different cage locations closed house. research material 5,051 laying hens aged 28 weeks. House system house, arranged form frame A. were housed at densities 500 cm 2 per hen. Research feed is complete code 324 KJ produced by PT. Charoen Pokphand Indonesia. method comparative, comparing on locati...

The aim of this study was to investigate beak surface temperature changes stress induced by fear resulting from tonic immobility using infrared thermography in laying hens. It also examined whether temperatures differed among brown and white lines. based on 89 hens both lines: 45 White Leghorn birds 44 Hy-Line birds. Beak measured with immediately before after testing. average obtained the uppe...

The current study was carried out to evaluate the effect of phytogenic feed additive (PFA) on egg production performance in Hy-Line brown layer birds. A flock size 14190 birds selected commercial poultry farm which maintained with standard management practices at Spain. baseline data (T1) recorded for 20 days, thereafter, were fed PFA (500 g/ton) (T2) supplemented 11 days. parameters viz. numbe...

In a volume-limited sample of 63 ultracool dwarfs of spectral type M7–M9.5, we have obtained highresolution spectroscopy with UVES at the Very Large Telescope and HIRES at Keck Observatory. In this first paper we introduce our volume-complete sample from DENIS and 2MASS targets, and we derive radial velocities and space motion. Kinematics of our sample are consistent with the stars being predom...
