Immunogenicity and safety of Queensland V4 and Ulster 2C strains of Newcastle disease virus given to maternally immune, newly hatched chickens by nebulization.
Commercial chickens with a high level of maternal antibodies for Newcastle disease were vaccinated when newly hatched with Queensland V4 or Ulster 2C Newcastle disease virus (NDV) strains by nebulization. The exposure time to a fine aerosol of vaccine produced with an ultrasonic nebulizer was 60 sec. The chickens were challenged oculonasally with virulent NDV strain Texas GB in weekly intervals...
متن کاملEnergy utilization in newly hatched chicks.
The changes in body weight and composition were examined in broilers that either had immediate access to feed and water or had not been fed for 48 h posthatch. Chicks without access to feed decreased in BW by 7.8% in the 48 h posthatch, which was equivalent to 5.3 kcal/45 g chick/d. However, during this period the small intestines increased in weight and protein content by 80% or more. The decr...
متن کاملUnsupervised statistical learning in newly hatched chicks
The ability to extract probabilistic information from visual inputs has been reported in human adults and infants (reviewed in [1,2]), and in adults of non-human species, though only under supervised (conditioning) procedures [3]. Here, we report spontaneous sensitivity to the probabilistic structure underlying sequences of visual stimuli in newly hatched domestic chicks using filial imprinting...
متن کاملLocal immunity against Newcastle disease virus in the newly hatched chicken's respiratory tract.
Inoculation of 200 mean egg infectious doses (EID(50)) of lentogenic Newcastle disease virus strain B1 (NDV-B1) into the air sac of 4-day-old specific-pathogen-free chicks provided significant protection against challenge of the air sac with 100 chicken mean lethal doses (LD(50)) of velogenic NDV-H but no protection against reinfection when the challenge was by the eye. Conversely, inoculation ...
متن کاملImmunogenicity of the Multi-Epitopic Recombinant Glycoproteins of Newcastle Disease Virus: Implications for the Serodiagnosis Applications
Background: Newcastle disease virus (NDV) is a dangerous viral disease, infecting a broad range of birds, and has a fatal effect on the poultry industries. The attachment and consequently fusion of the virus to the host cell membrane is directed by the two superficial glycoproteins, the hemagglutinin-neuraminidase (HN) and the fusion (F) which is considered as the important tar...
