Broiler Chickens
The Life of: Broiler Chickens Chickens reared for meat are called broilers or broiler chickens. They originate from the jungle fowl of the Indian Subcontinent. The broiler industry has grown due to consumer demand for affordable poultry meat. Breeding for production traits and improved nutrition have been used to increase the weight of the breast muscle. Commercial broiler chickens are bred to be very fast growing in order to gain weight quickly. In their natural environment, chickens spend much of their time foraging for food. This means that they are highly motivated to perform species specific behaviours that are typical for chickens (natural behaviours), such as foraging, pecking, scratching and feather maintenance behaviours like preening and dust-bathing. Trees are used for perching at night to avoid predators. The life of chickens destined for meat production consists of two distinct phases. They are born in a hatchery and moved to a grow-out farm at 1 day-old. They remain here until they are heavy enough to be slaughtered. This document gives an overview of a typical broiler chicken’s life. The Hatchery The parent birds (breeder birds - see section at the end) used to produce meat chickens have their eggs removed and placed in an incubator. In the incubator, the eggs are kept under optimum atmosphere conditions and highly regulated temperatures. At 21 days, the chicks are ready to hatch, using their egg tooth to break out of their shell (in a natural situation, the mother would help with this). Chicks are precocial, meaning that immediately after hatching they are relatively mature and can walk around. -
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

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. -

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. -

National Chicken Council's Broiler Breeder Welfare Guidelines
NATIONAL CHICKEN COUNCIL ANIMAL WELFARE GUIDELINES AND AUDIT CHECKLIST FOR BROILER BREEDERS Approved by NCC Board of Directors June 2017 NATIONAL CHICKEN COUNCIL 1152 15TH Street NW Suite 430 Washington DC 20005 phone (202) 296-2622 Contents NCC Animal Welfare Guidelines NCC Animal Welfare Audit Checklist Guidance for Conducting Audits Under NCC Animal Welfare Guidelines Standard Contract for Audits Under NCC Animal Welfare Guidelines Appendix NATIONAL CHICKEN COUNCIL ANIMAL WELFARE GUIDELINES The National Chicken Council (NCC) is the national trade association representing vertically integrated broiler producer-processors. NCC recommends the following guidelines to its members to assure the humane treatment of animals and to promote the production of quality products. Preface An animal is considered to be in a good state of welfare “…if (as indicated by scientific evidence) it is healthy, comfortable, well nourished, safe, able to express innate behavior, and if it is not suffering from unpleasant states such as pain, fear, and distress” (OIE). Animals’ physical needs are relatively easily discussed, described, and studied, but their mental states and needs can be more difficult to characterize. We recognize that this is an ongoing discussion and evolving science. With that in mind, the NCC Animal Welfare Guidelines are updated regularly to include new science-based parameters. The NCC Animal Welfare Guidelines have been developed to evaluate the current commercial strains of broiler breeder chickens by auditing how these birds are raised, housed, managed and transported to slaughter at the end of their production cycle. It is important to note that such standards may not be appropriate for other types of poultry as management practices may differ.
