Newsletter Kepro January 2017 NEWSLETTER KEPRO JANUARY 2017 FEATHER PECKING AND CANNIBALISM IN POULTRY Feather pecking and cannibalism remain major welfare issues in the laying hen industry. In large flocks of birds with intact beaks, feather pecking and cannibalism are much more difficult to control, which will probably result in more feather damage and increased mortality levels. Different forms of bird-to-bird pecking can be distinguished: - Gentle feather pecking: gentle pecks to the tips of the feathers. - Severe feather pecking: this is the more damaging form, which includes forceful pecks and vigorous pulls. This often results in removal of the feathers. The plucked feathers are frequently eaten by the pecker. In the denuded body areas of the victim, cannibalistic tissue pecking can develop, resulting in the wounding and death of the victim. - Aggressive pecking: these pecks are directed to the head or neck of the bird and are used to maintain the dominance hierarchy. Aggressive pecking usually results in little damage in laying hens. Feather pecking can result in poor plumage, patches of feather loss, skin damage and even death. Where feather pecking develops into injurious pecking and the protective function of the bird’s plumage is lost, cannibalism can be triggered. There are different causes of feather pecking behavior: - Stress. Some breeds are more prone to stress and are more likely to show feather pecking behavior. - Sudden, unexpected changes in ration. - Parasites, like red mite and chicken lice. - Suboptimal nutrition intake. - Lighting variations. Treatment and management If you come across a flock with feather pecking behavior, there a few things which need to be checked: 1. Do the birds eat the feathers? If this is the case, then it is likely that a nutritional problem is the cause of the behavior. Also, if you can see that they are pecking especially at the gland at the vent, it is likely that they are lacking nutritionals. This gland is producing a salty substance, which is attractive if they lack minerals. If you suspect a nutritional problem, add minerals, amino- acids and vitamins to the drinking water. Products to be used: Vitamino Trace Oral, Amino Acid Oral. Image 1 - Gland at the vent which produces a salty oil. ECTO BLASTER 1,000 ml TL1683 V06-16 (Essential oils) COMPOSITION: Essential oils (Neem oil, Eucalyptus oil, Citronella oil) INDICATIONS: Ecto Blaster can be used to combat and prevent mites (including red fowl mite, Dermanyssus gallinae, Northern fowl mite Ornithonyssus sylviarum, Tropical fowl mite, Ornithonyssus bursa and Scaly leg mite (nemidocoptes mutants) ticks, biting lice (Mallophaga) and flies in poultry. Ecto Blaster can be used in a fully occupied barn, in the presence of water and food. PRECAUTIONS: Use safety masks, gloves & goggles. If contact with eyes or skin occurs, wash with water. To prevent harming honey bees: Apply only during late evening, night, or early morning. SIDE-EFFECTS: None. DOSAGE AND ADMINISTRATION: Shake well before use. During infestations : Mix 150 ml of Ecto Blaster with 5 liters of water and spray thoroughly (using a spray gun) on the chickens, cage surfaces and the inside walls of the barn. Repeat dosage after 2 days. Prevention : Mix 100 ml of Ecto Blaster with 5 liters of water and spray on the chickens, cage surfaces and the inside walls of the barn once a week. The prepared solution should be sprayed within 12 hours. VETERINARY USE ONLY VETERINARY WITHDRAWAL PERIOD: None. STORAGE: Store closed in a cool and dry place. Batch no. : : Man. date Exp. date : KEPRO B.V. - Maagdenburgstraat 17 - 7421 ZA Deventer - Holland E-mail: [email protected] Web: www.kepro.nl 2. Is there any sign of parasites? For lice, look onto the chickens between the feathers on the skin. For Red mite, do not only look onto the chickens, but also in the building. They like to hide in dark spots. If there are parasites, treat the parasites with Ecto blaster or Kepromec Oral. Please note, that if you are using Kepromec Oral, you also need to treat the building with an appropriate treatment, like disinfectants or insecticide. For more information about Red mite in chicken, you can also read the Kepro newsletter from August 2016 in the Kepro Academy. 3. Are there any recent changes in ration? Avoid sudden changes in ration, by slowly mixing the new ration into the old ration. Give the birds vitamins like Powervit wsp or Stress aid wsp at moments which can cause stress, like feed changes or vaccination. 4. Avoid lighting variations or too much bright light. Lighting should be installed to give an even distribution of light and should incorporate some means of adjusting light intensity to control aggressive pecking when this occurs.

  • Chickens As Patients - UEP2013 - VIN
    7/27/2020 Chickens as Patients - UEP2013 - VIN Chickens as Patients AAVAC-UPAV 2013 Anna Meredith, MA, VetMB, PhD, CertLAS, DZooMed, MRCVS Royal (Dick) School of Veterinary Studies, University of Edinburgh, Scotland, UK Introduction The keeping of non-commercial backyard poultry is increasing greatly in popularity. Ducks, geese, pheasants, guinea fowl and other species may all be kept, but chickens are probably the most common species presented in general practice. People keep chickens for different reasons, including just having a few hens for private egg production and consumption, breeding of exhibition or "fancy" birds, small layer or meat bird flocks, or as true pets that also help to weed the garden. Chicken owners will vary from very experienced to complete novices. For these types of poultry, the local small animal or mixed veterinary practitioner is likely to be called upon rather than an experienced commercial poultry vet, although this may well be after advice has been sought from the breeder, agricultural merchant or internet first and various treatments applied. Many owners become very attached to their birds and invest time and money in their care, and will expect their veterinary surgeon to be knowledgeable, able to advise on general husbandry and management and to treat any problems effectively. The domestic chicken is descended from the red junglefowl (Gallus gallus), but has been domesticated into a large variety of breeds. Choice of breed usually depends on the purpose of keeping the chicken. Bantams are often kept if space is limited; these are small varieties with correspondingly small eggs, and most large breeds have a bantam (miniature) version.

  • Controlling Feather Pecking and Cannibalism in Laying Hens Without
    CONTROLLING FEATHER PECKING & CANNIBALISM IN LAYING HENS WITHOUT BEAK TRIMMING A Compassion in World Farming Report by Heather Pickett MSc BSc (hons) October 2009, revised March 2011 Registered Charity No. 1095050 Compassion in World Farming is grateful to The Rufford Maurice Laing Foundation whose funding made this research possible. www.rufford.org EXECUTIVE SUMMARY Hens are often beak trimmed to reduce the risk of welfare problems caused by feather pecking and cannibalism. The consequences of beak trimming for welfare include trauma during the procedure, pain due to tissue damage and nerve injury, loss of normal function due to reduced ability to sense materials with the beak, and loss of integrity of a living animal. This report reviews the evidence from the scientific literature and from practical experience, which demonstrates that feather pecking and cannibalism can be controlled in non-cage systems without beak trimming through (i) the use of appropriate strains and selective breeding to further reduce the hens’ propensity to feather peck and (ii) good design of non-cage systems and implementation of a range of preventive management practices. Experience in other European countries where beak trimming has been prohibited indicates that, with experience, laying hens can be successfully managed in non-cage systems without beak trimming. The Department for Environment, Food and Rural Affairs has repealed the ban on the beak trimming of laying hens in England, which was due to come into force on 1st January 2011. Instead, the government has merely banned the use of the hot blade method for beak-trimming, except in emergencies on-farm, while allowing beak-trimming by the infra-red (IR) beam method to continue.

  • Impact of Nutritional Factors on Feather Pecking Behaviour of Laying Hens in Non-Cage Housing Systems
    Impact of nutritional factors on feather pecking behaviour of laying hens in non-cage housing systems 1* 2 1 1 M.M. VAN KRIMPEN , R.P. KWAKKEL , G. ANDRÉ , C.M.C. VAN DER PEET-SCHWERING , L.A. 3,4 2 DEN HARTOG and M.W.A.

Many factors influence feather pecking behaviour, but in this review we will focus on nutritional factors. Dietary deficiencies, resulting in inaccurate delivery of nutrients, may increase feather pecking behaviour and cannibalism. Severe feather pecking has been demonstrated in birds that were fed too low mineral levels, protein levels or amino acid levels (methionine, arginine). Feeding high-NSP diets, low energy diets, or roughages reduced feather pecking. Providing additional grain or straw in the litter during rearing could result in lower levels of feather pecking behaviour in adult stages. Nutritional factors seem to reduce feather pecking behaviour in laying hens if these factors increase the time related to foraging, feed intake and satisfying. Laying hens may spend more time on these behaviours when they are fed 1) mash diets in stead of crumbles or pellets, 2) low energy diets, 3) high (in-)soluble fibre diets or 4) roughages.

  • Improving Feather Cover a Guide to Reducing the Risk of Injurious Pecking Occurring in Non-Cage Laying Hens
    Improving Feather Cover A guide to reducing the risk of injurious pecking occurring in non-cage laying hens 2013 © University of Bristol Introduction This guide summarises strategies available to reduce the risk of injurious pecking occurring in non- cage laying hens during both rearing and laying. Beak-trimming and alterations to lighting are commonly practised to control injurious pecking, but these are not ideal in terms of bird welfare. The strategies discussed in this guide offer many ways of reducing the risk of injurious pecking occurring, which may also offer other benefits. Injurious pecking (IP) is an umbrella term covering a group of behaviours; gentle and severe feather pecking, vent pecking, and cannibalistic pecking. Gentle feather pecking (GFP) consists of gentle pecks to the tips of the feathers. This type of feather pecking (FP) usually does not result in much damage and is often ignored by the recipient. It can indicate a welfare problem in the bird performing the behaviour, and precede more serious pecking. Severe feather pecking (SFP) causes the most damage to Cannibalistic pecking occurs when SFP the recipient; it consists of forceful pecks and pulls of has led to feather loss and bald feathers that are frequently eaten and results in feather patches. Pecking can then continue on loss especially on the back, vent and tail area. Victims of the skin, leading to wounds and may SFP often initially move away, squawk or confront the eventually lead to the victim’s death pecker in response to receiving SFP, which are painful. If due to excessive blood loss, tissue SFP continues, however, victims have also been observed damage & infections.

  • Beak Trimming Methods -Review
    1619 Beak Trimming Methods -Review - P. C. Glatz* Pig and Poultry Production Institute, South Australian Research and Development Institute Roseworthy, South Australia, 5371, Australia ABSTRACT : A review was undertaken to obtain information on the range of beak-trimming methods available or under development. Beak-trimming of commercial layer replacement pullets is a common yet critical management tool that can affect the performance for the life of the flock. The most obvious advantage of beak-trimming is a reduction in cannibalism although the extent of the reduction in cannibalism depends on the strain, season, and type of housing, flock health and other factors. Beak-trimming also improves feed conversion by reducing food wastage. A further advantage of beak-trimming is a reduction in the chronic stress associated with dominance interactions in the flock. Beak-trimming of birds at 7-10 days is favoured by Industry but research over last 10 years has shown that beak-trimming at day-old causes the least stress on birds and efforts are needed to encourage Industry to adopt the practice of beak-trimming birds at day-old. Proper beak-trimming can result in greatly improved layer performance but improper beak-trimming can ruin an other wise good flock of hens. Re-trimming is practiced in most flocks, although there are some flocks that only need one trimming. Given the continuing welfare scrutiny of using a hot blade to cut the beak, attempts have been made to develop more welfare friendly methods of beak-trimming. Despite the developments in design of hot blade beak-trimmers the process has remained largely unchanged.

Dissertations, No. 1755 ISSN: 0345-7524 ISBN: 978-91-7685-796-0 Front cover: Red Junglefowl chicks Photo: Maria Ericsson Copywright © Maria Ericsson unless otherwise noted Printed by LiU-Tryck, Linköping, Sweden, 2016 Till mina stjärnor Abstract The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters. The domestication of chickens (Gallus gallus) was initiated around 8000 years ago, and today we see clear phenotypic and genotypic alterations when comparing domestic breeds with the wild ancestor. Our modern domestic production breeds have been selected for, and still undergo heavy selection for high meat and egg yields. Beside obvious morphological changes, studies investigating behavioural differences between the ancestral Red Junglefowl and domestic breeds show, for example, differences in fearfulness, foraging strategies, exploratory behaviour and sociality. The modern production environments are intense and already from hatch chicks are exposed to harsh conditions. From an animal welfare perspective, the production environment contain many stressful aspects. The shift in stressor types between wild and captive conditions have likely contributed to alterations in stress tolerance when comparing domestic breeds to the wild ancestors.
