1. Intermittent fasting in chickens : Physiological mechanisms and welfare implications for broiler breeders
Sammanfattning : Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals.

2. A flying start : Adapted hatching and post-hatch feeding in broiler chickens
Sammanfattning : Conventional hatching practices do not involve provision of feed and water to broiler chickens before placement at the rearing farm. This can pose problems, especially for early hatchlings, which remain feed-restricted for a considerable period due to biological variation in hatch time. LÄS MER
3. Never wake a sleeping broiler : An undisturbed natural resting pattern in broilers
Sammanfattning : The importance of sleep and rest for animals is well known, but rarely mentioned and considered in the handbooks for broiler production, nor when welfare issues are discussed in relation to the production settings. Resting behaviours make up a large part of the daily time budget of broilers, making the quality of rest highly important for the welfare of the birds. LÄS MER
4. Feed for defence : can dietary supplements modulate broiler gut microbiota and guard against Campylobacter?
Sammanfattning : The bacteria Campylobacter jejuni is the causative agent of a disease in humans called campylobacteriosis and is the most commonly reported zoonosis in the European Union, with the primary source of infection often traced to broiler products. While low overall C. LÄS MER
5. Protein supply in organic broiler production using fast-growing hybrids : welfare and performance aspects
Sammanfattning : The broiler's requirements of sulphur amino acids (AA) are high; however, currently available organic protein feedstuffs generally contain only low levels. According to national organic standards, fast-growing broilers in organic production are allowed to be slaughtered at 70 d, provided that their average growth rate does not exceed 50 g/day. LÄS MER
