3. Effect of the competitive exclusion culture on the growth, blood parameters, leg health, and innate immunity of broiler chickens

Abstract

The primary aim of poultry production is to obtain a high yield and quality end product. To reduce the risk of disease, many direct-fed microbial products have been developed. That appears to be an excellent tool for disease prevention.

9. 25 lat występowania zakaźnego wirusowego zapalenia żołądka kurcząt brojlerów w Polsce.

Abstract

Transmissible viral proventriculitis (TVP), in broiler chickens, is characterized by poor growth, retarded feathering, diarrhea with undigested food, and increased mortality mainly in broilers, broiler breeders and layer hens. Obviously, it has a negative economic impact on the poultry industry. According to the review of the national literature, the first cases of TVP in Poland were diagnosed in November 1998. At that time, the disease occurred with relatively low intensity. As in other European countries, a renewed increase of TVP in Poland took place from 2016. Currently, the disease occurs throughout the country with varying intensity, although it seems to have increased in recent years. For decades, many viral families have been implicated with TVP, including Adenoviridae, Reoviridae, Coronaviridae, Circoviridae, Anelloviridae and Astroviridae. Chicken proventricular necrosis virus (CPNV), and small ssDNA viruses recently described by Chinese scientists, are now recognized as the most probable cause of transmissible viral proventriculitis. In practice, TVP is a disease of chickens, mostly 2-8 weeks old. The clinical signs of the disease are nonspecific. Mortality in flocks with TVP is 3.03–4.49%. At necropsy, the most common finding is enlarged or dilated proventriculus with thickened wall. Histopathologically, inflammation of the proventricular glands is the most frequently found. Also necrosis, hyperplasia, or both conditions of the glandular epithelium; dilated glands; and occasionally fibrin deposition, fibrosis, and hemorrhages are observed. There are no specific treatments and prevention or control measures for TVP. [ABSTRACT FROM AUTHOR]

14. Review on skeletal disorders caused by Staphylococcusspp. in poultry

Abstract

AbstractLameness or leg weakness is the main cause of poor poultry welfare and serious economic losses in meat-type poultry production worldwide. Disorders related to the legs are often associated with multifactorial aetiology which makes diagnosis and proper treatment difficult. Among the infectious agents, bacteria of genus Staphylococcusare one of the most common causes of bone infections in poultry and are some of the oldest bacterial infections described in poultry. Staphylococci readily infect bones and joints and are associated with bacterial chondronecrosis with osteomyelitis (BCO), spondylitis, arthritis, tendinitis, tenosynovitis, osteomyelitis, turkey osteomyelitis complex (TOC), bumblefoot, dyschondroplasia with osteomyelitis and amyloid arthropathy. Overall, 61 staphylococcal species have been described so far, and 56% of them (34/61) have been isolated from clinical cases in poultry. Although Staphylococcus aureusis the principal cause of poultry staphylococcosis, other Staphylococcusspecies, such as S. agnetis, S. cohnii, S. epidermidis, S. hyicus, S. simulans, have also been isolated from skeletal lesions. Antimicrobial treatment of staphylococcosis is usually ineffective due to the location and type of lesion, as well as the possible occurrence of multidrug-resistant strains. Increasing demand for antibiotic-free farming has contributed to the use of alternatives to antibiotics. Other prevention methods, such as better management strategies, early feed restriction or use of slow growing broilers should be implemented to avoid rapid growth rate, which is associated with locomotor problems. This review aims to summarise and address current knowledge on skeletal disorders associated with Staphylococcusspp. infection in poultry.
