According to Linscott"s Directory of Immunological and Biological Reagents (1994/95) the commercial availability of egg-yolk antibodies (IgY) is extremely low. For preparation, cleaning and detection of IgY it would be of advantage to have a "Protein Y" available analogous to protein A and protein G for mammalian antibodies. Until now, the search for "Protein Y" was unsuccessful. IgY has been u...
The identification of infected commercial poultry flocks has become a pivotal component of efforts to reduce the incidence of egg-associated transmission of Salmonella enteritidis to humans. To assess the sensitivity with which testing for specific antibodies in egg yolks can be applied to detect S. enteritidis infection in laying chickens, groups of hens were orally inoculated with either 10(3...
Ostrich raising around the world have some key factors and farming profit depend largely on information and ability of farmers to rear these animals. Non fertilized eggs from ostriches are discharged in the reproduction season. Staphylococcus aureus and Escherichia coli are microorganisms involved in animal and human diseases. In order to optimize the use of sub products of ostrich raising, non...
One of the most common causes of salmonellosis of man and poultry is Salmonella Enteritidis which is often found in the digestive system of adult birds. The infected birds do not display any evident clinical symptoms and, at the same time, they excrete the bacteria into the surrounding environment. Studies are carried out by standard microbiological procedures which include the isolation of Sal...
BACKGROUND IgY antibodies are serum immunoglobulin in birds, reptiles and amphibians, and are transferred from serum to egg yolk to confer passive immunity to their embryos and offspring. Currently, the oral passive immunization using chicken IgY has been focused as an alternative to antibiotics for the treatment and control of diarrhea in animals and humans. This systematic review was focused ...
Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein. It has been previously described as a carrier of peptides or proteins to increase their immunogenicity in different animal species, but its activity has never been evaluated in chickens. In this work, the use of BLS to improve the antibody response against bovine rotavirus (BRV) VP8d protein in laying hens was...
this present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. the results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive whereas egg production, feed...
in this experiment, a total of 128 hy-line w36 hens at 63 weeks of age were used. the hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. all birds were housed in commercial cages, had ad libitum access ...
چکیده معضل چاقی به عنوان عارضه ای جدی برای زندگی بی تحرک و ماشینی، مورد توجه اغلب مراکز بهداشتی و درمانی دنیا قرار گرفته است. چاقی عامل زمینه ساز و در واقع عامل خطری برای بروز بیماری های قلبی - عروقی است که عموماً با کاهش طول عمر مورد انتظار و افزایش بیماری همراه است. هدف پژوهش حاضر تأثیر 12 هفته تمرینات ویبریشن کل بدن، تمرینات هوازی و تمرینات ترکیبی( هوازی و ویبریشن کل بدن) بر ترکیب بدنی زنان ...
