INFORMATION ABOUT POSTER SESSIONS We are piloting a new way to increase the attention of poster presentations by dividing posters into sessions of 5-15 posters around similar subjects. Each poster session will be introduced and summarised at the end of one oral session by the chairman of that session. Posters in the same session will be positioned close together in the exhibition area. Authors are asked to stand by their posters especially during the coffee break/ start of lunch break that follows and participants with special interest in these posters are encouraged to visit them at this time. However, to avoid crowding at the posters, poster authors are also welcome to stand by their posters at other poster sessions, thus allowing participants to visit posters during all breaks. As this is a new system, aimed at increasing the communication value of posters, we hope you are fl exible and try to help us make the system work! Posters will further be divided into two main groups (1 and 2): the fi rst group is available Wednesday to Thursday and the second Friday to Saturday 10 Reprinted from Hänninen, L & Valros, A.(eds), Proceedings of the 38th International Congress of the ISAE (2004).

  • Commercial Egg Tip
    The University of Georgia Cooperative Extension Service College of Agricultural and Environmental Sciences / Athens, Georgia 30602-4356 NOVEMBER 2010 COMMERCIAL EGG TIP . A BRIEF LOOK AT DIFFERENT HOUSING SYSTEMS FOR COMMERCIAL LAYERS Concerns for laying hens’ welfare began in the 1960’s and led to an aversion to eggs produced by hens housed in conventional battery cages. As a result the European Union (EU) has banned the use of battery cages beginning in January 2012. This move has resulted in the development of alternative housing systems for laying hens. While the EU ban does not currently apply to the commercial egg producers in the United States, some states have made moves towards banning the use of battery cages for laying hens, the most recent being California. With the passing of Proposition 2 in California there has been a renewed effort to develop alternative housing systems to meet all the requirements of good hen welfare. A number of different systems are currently being used to house laying hens, but the majority of laying hens in the US are still housed in conventional cages. Each of the systems used have advantages and disadvantages that vary based on location, management, and genetic strain of the hens. Conventional Cage Housing System Conventional battery cages for laying hens were first developed in the US during the 1920s to 1930s. The system was developed to reduce the incidence of disease and parasites and also to reduce cannibalistic pecking. Cages makes management of the birds easier and requires less space than the other systems. No bedding material is used in this system as the cages are suspended above the floor allowing the bird droppings to fall through the mesh floors and collect below the cages.

  • Perch Arrangements in Small-Group Furnished Cages for Laying Hens
    ©2007 Poultry Science Association, Inc. Perch Arrangements in Small-Group Furnished Cages for Laying Hens H. Wall1 and R. Tauson Department of Animal Nutrition and Management, Swedish University of Agricultural Sciences, S-753 23 Uppsala, Sweden Primary Audience: Advisors, Researchers, Quality Assurance Personnel, Plant Managers SUMMARY In 2 trials, including 2,768 birds in total, 3 different perch arrangements were evaluated in furnished 8-hen cages for laying hens. The hybrids used were Lohmann Selected Leghorn and Lohmann Brown in trial 1 and Hy-Line White and Hy-Line Brown in trial 2. The furnished cages were identical in all other respects than the arrangement of perches. A perch was either fitted across the cage, providing 12 cm of perch per hen, or 2 perches were installed in a cross, implying 15 cm per hen. Although the perches arranged in a cross provided more perch per hen than the single perch fitted across the cage, perch use at night by the birds was similar or lower as compared with the single perch. Hence, the way perches are arranged in the cage may be as important as perch length itself to achieve a high use at night. Perch arrangement did not affect production, mortality, or egg quality. Compared with a conventional battery cage, also included in the trials, hygiene was inferior in the furnished cages, but there was no difference in proportions of dirty eggs. Differences in proportions of cracked eggs were found between furnished and conventional cages in 1 of the trials. However, on the whole, production, mortality, and egg quality were at similar levels in all cage models.

  • Effects on Bone Health and Keel Bone Damage in Laying Hens
    Opportunities for Exercise during Pullet Rearing: Effects on Bone Health and Keel Bone Damage in Laying Hens by Teresa Casey-Trott A Thesis Presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Animal Biosciences Guelph, Ontario, Canada © Teresa Marie Casey-Trott, September, 2016 ABSTRACT OPPORTUNITIES FOR EXERCISE DURING PULLET REARING: EFFECTS ON BONE HEALTH AND KEEL BONE DAMAGE IN LAYING HENS Teresa Casey-Trott Advisor: University of Guelph, 2016 Professor T. M. Widowski This thesis is an investigation of the effect of providing opportunities for exercise on long term bone health of laying hens, with an emphasis on keel bone damage. Osteoporosis in laying hens is a welfare concern as it increases the risk of bone fractures. The keel bone is especially susceptible to fracture during the laying period. Providing opportunities for exercise during pullet rearing, a period of substantial musculoskeletal growth, offers a proactive approach to reducing osteoporosis by stimulating osteogenesis. The main objective was to determine whether rearing environments that offer different opportunities for exercise have long term effects on bone health and keel bone damage of laying hens. A secondary objective was to determine whether adult housing systems that offer different opportunities for exercise have an effect on bone health and keel bone damage of laying hens. Additionally, behavioural differences between hens with or without keel bone fractures were assessed, and an accelerometer to measure inactivity in laying hens was validated. Aviary-reared pullets had greater values for bone cross-sectional area, bone mineral density, bone mineral content, and bone breaking strength in wing and leg bones compared to bones of conventionally-reared pullets.

  • Keeping Laying Hens in Furnished Cages and an Aviary Housing System Enhances Their Bone Stability M
    British Poultry Science Volume 46, Number 5 (October 2005), pp. 536–544 Keeping laying hens in furnished cages and an aviary housing system enhances their bone stability M. LEYENDECKER, H. HAMANN, J. HARTUNG1, J. KAMPHUES2, 3 4 1 U. NEUMANN ,C.SU¨RIE AND O. DISTL Institute of Animal Breeding and Genetics, 1Institute of Animal Hygiene and Animal Welfare, 2Institute of Animal Nutrition, 3Clinic for Poultry and 4Farm for Education and Research in Ruthe, University of Veterinary Medicine Hannover, Hannover, Germany Abstract 1. Tibia and humerus breaking strength of Lohmann Silver hybrids kept in conventional cages, furnished cages and an aviary with outdoor run were examined in two production cycles. Each trial lasted a full laying period; feeding, management and healthcare were identical for all hens. In both trials bone strength was investigated at the end of laying months 6, 9 and 14. 2. The objective was to determine if bone strength increases when hens are kept in alternative housing systems, especially in furnished cages, and whether hen age affects bone stability. 3. The results indicated that housing system influenced bone breaking strength, which was consistently higher for hens in the aviary compared to hens in conventional and furnished cages. Furthermore, humerus breaking strength was higher for hens in furnished cages compared to conventional cages. No significant difference regarding tibia breaking strength was found between conventional and furnished cages. 4. Our results showed that lack of exercise contributed to the problem of weak bones more than did calcium depletion from eggshell formation. 5. Tibia breaking strength increased during the last third of the production cycle, whereas humerus breaking strength remained unaffected by hen age.

  • Animal Welfare Is Essential to the Sustainability of the Poultry Industry
    //////////// extension.umd.edu ///////////////////////////////////////////////////////////////////////////////////////////////////////////// FS—1136 | September 2020 //////////// Animal Welfare is Essential to the Sustainability of the Poultry Industry Sustainability is “the ability to be maintained at a certain rate or Animal Welfare Assessments Assure level.” In other words, systems must operate to meet the Consumers that Production Systems Follow current population’s needs without compromising the ability of Industry Standards future generations to meet their needs. In the past, sustainable Animal welfare can be defined as “the quality of life as systems were those that minimized the depletion of resources perceived by the animal” (Bracke and Hopster, 2006). Animal or contaminant emissions that were harmful to the welfare assessments provide the public with assurance that the environment. Today sustainability has a much broader food products they consume come from production systems application and systems are unsustainable if the public finds where the animals are monitored and evaluated according to a any effect of the system on the environment, human health, or producer organization’s published standards. On-farm animal animal welfare to be unacceptable (Broom, 2019). welfare assessments are centered on maintaining compliance Which factors the public considers more important than others, with standards for raising animals (Weimer et al., 2018) by and the order of their importance, varies over time (Broom, evaluating the impacts of resource and animal management 2019). Farm animal welfare is one factor that remains practices on the health and emotions of the animals.

  • Beak Trimming
    POULTRY WELFARE STANDARDS AND GUIDELINES – BEAK TRIMMING SUPPORTING PAPER PUBLIC CONSULTATION VERSION Prepared by the Poultry Standards and Guidelines Drafting Group, Oct 2016 ISSUE Should beak trimming be carried out on poultry and what are acceptable procedures. RATIONALE Feather pecking, peck injury and peck mortality (cannibalism) in poultry occurs at variable rates and may unpredictably become severe and cause high rates of distress, injury and death in a flock (American Veterinary Medical Association, 2010). It occurs in all production systems. Advantages of beak trimming may include ‘reduced pecking, reduced feather pulling, reduced cannibalism, better feather condition, less fearfulness, less nervousness, less chronic stress and decreased mortality. Welfare disadvantages may include reduced ability to feed following beak trimming/treatment, short-term pain, perhaps chronic pain, and acute stress’ (United Egg Producers, 2014). RECOMMENDATIONS The drafting group considered current scientific knowledge and practice and agreed that standards were required to underpin poultry welfare for beak trimming. ANIMAL HEALTH AND WELFARE CONSIDERATIONS Birds may experience acute pain during the procedures of beak trimming due to the presence of nociceptors (pain receptors) in the tip of the beak. Neuroma formation in the beak as a result of beak trimming may also be associated with chronic pain. Beak trimming younger birds (less than one week of age) appears to avoid the long-term chronic pain that can occur in the stump of the beak when older birds are trimmed (Lunam et al., 1996). There are currently two routine beak trimming procedures, either infrared beak trimming of chicks at the hatchery, or hot blade trimming at 10 days old or younger.

The concentrations of serotonin were reduced, or furnished cages at 19 wk of age. The furnished cages whereas corticosterone was increased from 50 to 60 wk had wire floors and solid metal walls, with perches, of age in the hens housed in the battery cages (P < a dustbathing area, scratch pads, and a nestbox area 0.05) but not in those housed in the furnished cages, with concealment curtain.
