The welfare of egg-producing poultry is a topic of great concern to the poultry industry and to researchers in applied animal behaviour. It is also subject to increased legislation. Issues such as battery cages, space requirements, access to daylight and ''free-range'' eggs have attracted public interest.

One of the major welfare issues in cage-free housing systems is bone fracture. The goal of this research was to improve bone health in layers by building better pullet skeletons and to investigate limestone particle size (LPS) effects on bone health in conventional cages and cage-free housing systems. Study 1 was a preliminary study that compared conventional cages with litter floor pens in terms of performance, bone health, and eggshell quality from 33 to 47 wk of age. Caged hens had higher egg production and eggshell strength, and improved feed efficiency, but lower tibia bone mineral content compared to floor housed hens. Study 2 examined the effects of LPS fed from 7 to 17 wk of age on performance and bone health in conventional cage and aviary systems. The use of a limestone blend of fine and large particles (0.879 mm; LPS-Blend) rather than a fine limestone (0.431 mm; LPS-Fine) increased tibia bone mineral density (BMD) and alleviated incidence of curved keel bones at the end of the pullet phase. Study 3 investigated the subsequent effects of LPS (Study 2) during the layer phase. The LPS-Blend increased eggshell weight and alleviated keel bone indentations in the middle and end of the lay cycle (Study 3). Study 4 examined the effects of LPS fed from 9 to 17 wk of age on pullet and hen performance, bone health, and eggshell quality in deep litter systems. Hens fed LPS-Blend during the pullet phase had greater tibia BMD at onset of egg production and higher overall eggshell strength. Study 5 evaluated the effect of two layer strains on nest and perch use in aviary systems. White Leghorn hens had greater usage of perch and nest and preferred elevated tiers compared to Brown hens. In conclusion, the provision of LPS-Blend rather than LPS-Fine during the pullet phase improved bone mineralization at the onset of egg production and eggshell quality. Although White Leghorn hens had greater usage of resources in aviary systems; they had higher potential risk of bone fractures.

With an emphasis on the disease conditions of dogs, cats, horses, swine, cattle and small ruminants, Jubb, Kennedy, and Palmer's Pathology of Domestic Animals, 6th Edition continues its long tradition of being the most comprehensive reference book on common domestic mammal pathology. Using a body systems approach, veterinary pathology experts provide overviews of general system characteristics, reactions to insult, and disease conditions that are broken down by type of infectious or toxic insult affecting the anatomical subdivisions of each body system. The sixth edition now boasts a new full-color design, including more than 2,000 high-resolution images of normal and abnormal organs, tissues, and cells. Updated content also includes evolved coverage of disease agents such as the Schmallenberg virus, porcine epidemic diarrhea virus, and the porcine deltacoronavirus; plus new information on molecular-based testing, including polymerase chain reaction (PCR) and in-situ hybridization, keep you abreast of the latest diagnostic capabilities. Updated content includes new and evolving pathogens and diagnostic techniques. Updated bibliographies give readers new entry points into the rapidly expanding literature on each subject. NEW! High-resolution color images clearly depict the diagnostic features of hundreds of conditions. NEW! Introduction to the Diagnostic Process chapter illustrates the whole animal perspective and details the approaches to systemic, multi-system, and polymicrobial disease. NEW! Coverage of camelids is now included in the reference’s widened scope of species. NEW! Team of 30+ expert contributors offers the latest perspective on the continuum of issues in veterinary pathology. NEW! Expanded resources on the companion website include a variety of helpful tools such as full reference lists with entries linked to abstracts in Pub Med and bonus web-only figures. NEW! Full-color design improves the accessibility of the text.

The main theme of this year’s congress is 'Animal lives worth living'. This theme focuses on our responsibility for all animals kept or influenced by humans, to ensure that we can provide a life for them that takes into account all relevant aspects of animal welfare, aided by applied ethology as the key scientific discipline. This not only means avoiding and alleviating suffering but also promoting resilience and positive experiences. By monitoring and interpreting animal behaviour, we gain important insights into each of these aspects of quality of life.
