Performance and welfare of laying hens in conventional and enriched cages
167
TL;DR: Overall, laying performance, exterior egg quality measures, plumage condition, and immunological response parameters appear to be similar for hens housed in the 2 cage systems tested.

TL;DR: It appears that no single housing system is ideal from a hen welfare perspective and any attempt to evaluate the sustainability of a switch to an alternative housing system requires careful consideration of the merits and shortcomings of each housing system.

Animal welfare and society concerns finding the missing link.
TL;DR: Young adults in developed countries are distanced from agriculture and the meat industry needs to do a better job of communicating with them and researchers and industry need to determine optimum production levels instead of maximums.

Egg production and welfare of laying hens kept in different housing systems (conventional, enriched cage, and free range)
TL;DR: The hens in the FR system had additional space for optimum comfort and better feather and bone traits, but the dirty egg ratio, feed consumption, and foot lesions were higher than in CC and EC systems.

Digestion of plant tissue for analysis by ICP emission spectroscopy
TL;DR: In this article, a method of digesting plant tissue samples for multi-element analysis by inductively coupled plasma (ICP) emission spectroscopy was developed which does not require the use of HclO4.

The influence of strain and environmental factors upon feather pecking and cannibalism in fowls
B. O. Hughes,I. J. H. Duncan +1 more
TL;DR: It is suggested that although particular “causative factors” may sometimes be of overriding importance, the problem should generally be viewed in terms of the interaction between an individual bird and its environment.

Blood film preparation and staining procedures
TL;DR: In this article, the authors give direction and some standardization in the preparation of blood films used for morphologic evaluation in the clinical laboratory, which can be labeled as being state-of-the-art and methods applicable for laboratories in developing countries are quoted.

Multiple Concurrent Stressors in Chicks.3. Effects on Plasma Corticosterone and the Heterophil:Lymphocyte Ratio
TL;DR: In this paper, the effects of multiple concurrent stressors on female Hubbard × Hubbard chicks were studied in a 26-factorial experiment that employed as stressor treatments aerial ammonia (A, 0 or 125 ppm), beak trimming [B, sham handled or beak trimmed/cauterized on trial Day 1 (posthatch Day 10), coccidiosis (X, gavage with 0 or 6 × 105 sporulated Eimeria acervulina oocysts), intermittent electric shock (E,0 or between 2.9 and 8.7
