Aerobic bacteria isolated from eggs and day-old chicks and their antibacterial resistance in Shiraz, Iran
To study the putative transfer of antibiotic resistance from broiler breeders to human, hen’s eggs and theirday-old chicks were examined for the presence of bacteria. The most frequently isolated organisms indecreasing order were: Streptococcus spp., Bacillus spp., Staphylococcus spp., Klebsiella spp., Enterobacterspp. and Escherichia coli followed by Citrobacter spp., Proteus spp. and Pseudomo...
متن کاملNumerical Abstraction in Young Domestic Chicks (Gallus gallus)
In a variety of circumstances animals can represent numerical values per se, although it is unclear how salient numbers are relative to non-numerical properties. The question is then: are numbers intrinsically distinguished or are they processed as a last resort only when no other properties differentiate stimuli? The last resort hypothesis is supported by findings pertaining to animal studies ...
متن کاملSexing Day-Old Chicks on Small and Backyard Flocks
Vent sexing was developed in Japan and brought to North American poultry producers in the 1930s. Vent sexing is a skill that takes a long time to develop. It involves holding the chick upside down in one hand, expelling the fecal material, and everting (turning outward) the vent area. The producer can then look for the presence or absence of a rudimentary male sex organ. This process sounds muc...
متن کاملVirulence Determination of Three Iranian Isolates of Salmonella Enteritidis in Day-Old Layer Chicks
BACKGROUND: Salmonella Enteritidis (SE) infection in poultry is one of the most important concerns in poultry. Virulence and pathogenicity of the SE isolates from Iran have not been well studied so far. OBJECTIVES: In the present study, three Salmonella Enteritidis (SE) isolates were compared with a standard SE strain (PT21) for virulenc...
متن کاملColour vision of domestic chicks.
The colour vision of domestic chicks (Gallus gallus) was investigated by training them to small food containers decorated with tilings of grey and coloured rectangles. Chicks learn to recognise the colour quickly and accurately. Chicks have four types of single-cone photoreceptor sensitive to ultraviolet, short-, medium- or long-wavelength light. To establish how these receptors are used for co...
