The aim of this study was to determine the incidence of keel bone damage in laying hens kept in enriched cages, in aviaries, and in a free-range system. The study was conducted by 4 palpators who were randomly assigned 16 laying hens from each of three housing systems, i.e., a total of 48 hens per...

This review paper presents the most common welfare problems of broiler chickens. Contact dermatitis and musculoskeletal disorders that occur due to the fast chicken growth and increase in muscle mass burdening underdeveloped skeletal system are described. The resulting painful conditions make it...

This proceedings contains abstracts of papers from the XIV Scientific and Professional Symposium on the following themes: (1) animal diseases; (2) feeding and technology in poultry production; (3) ecology, welfare and veterinary practice in poultry farming; (4) quality and safety of poultry...

Bacteria of the genus Enterococcus are ubiquitous microflora of the digestive system of humans and animals. The species E. faecalis and E. faecium are most often pathogenic for pet birds. Development of resistance to antimicrobial substances is a significant problem in human and veterinary...

Mites cause the most important invasion in the intensive egg production. The most common is poultry invasion by red mite (Dermanyssus gallinae, PRM), Which as a hematophagous parasite leads to blood loss with consequent anaemia, causes severe irritation and stress by biting, With frequent...

The effect on the health, quality of hatching eggs and productivity of hens of heavy hybrids aged 18-61 weeks was investigated. Mineral preparation ADNEM (alluvial deposit of eroded minerals) added to the feed mixture proved very successful in chicken fattening and especially in improving...

The active metabolite of vitamin D, 1,25(OH)₂D₃ has many important roles in birds and mammals. In intensive production, timely monitoring of poultry health is important, with special reference to haematological and biochemical tests. The aim of this study was to determine the effect of adding...

Infectious bursal disease is one of the most important diseases in the early age of chicken production, causing losses due to mortality, stunting and selection of chickens, and long-term weakening of the immune mechanisms due to immunosuppression caused by direct damage to immunocompetent cells....

The aim of the study was to estimate greenhouse gas (GHG) emissions, i.e. methane (CH₄), nitrogen oxide (N₂O) and carbon dioxide (CO₂) from poultry production in Croatia in the last 10 years (2010-2020). Calculations of GHG emissions are based on the guidelines of the Intergovernmental Panel on...

Egg-laying hens are genetically selected in order to enable higher and prolonged production. This inevitably creates conditions that allow impairment of health and emergence of a number of diseases. The mentioned numerous predisposing factors make the basis for the selection of increasingly...
