Specific Chicken Egg Yolk Antibodies against Enterotoxigenic Escherichia coli K99 in Serum and Egg Yolk of Immunized Laying Hens
Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...
متن کاملS83 Egg Shell Colour in Free Range Laying Hens
Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...
متن کاملJejunal calcium permeability in laying hens during egg formation.
The permeability of the upper jejunum to water, calcium, potassium, sodium and chloride was measured in the immature pullet and then in the laying hen before and during egg-shell calcification by an in vivo perfusion procedure. Jejunal calcium permeability was constant throughout egg formation. Thus, the increase of net absorption during shell calcification was not due to enhanced mucosal capac...
متن کاملEffects of laying hens housing system on laying performance, egg quality characteristics, and egg microbial contamination
The objective of this study was to compare the performance, egg quality, and microbial contamination of egg shells from hens maintained in different housing systems, such as conventional and enriched cages, litter, and aviaries. The housing system significantly (P < 0.001) influenced the performance characteristics. The highest egg production, lowest daily feed consumption, and feed conversion ...
متن کاملEffects of Green Tea Powder on Laying Performance and Egg Quality in Laying Hens
This experiment was carried out to evaluate the effects of feeding green tea powder on laying performance and egg quality in hens. A total 180 “Tetran Brown” laying hens aged 40 weeks were assigned to 6 treatments in a completely randomized design. Each treatment consisted of five replicates accommodating six layers per replication. The experimental diets were a negative control containing no g...
