Hatching Egg Sanitation
Penetration of the hatching egg shell by microorganisms results in embryonic mortality, weak chicks, high chick mortality, and poor chick growth. The most effective sanitation system involves treating the eggs as soon as they are collected from the nest and before microorganisms penetrate the shell. Several recent research studies have examined the effectiveness, safety and ease of use of commo...
متن کاملBrightness dependence of colour preferences in herring gull chicks.
Since the classic study by TINBERGEN and PERDECK (1950) of the colour preferences of gull chicks reacting with the begging response to models of the parental beak, much has been published on spontaneous behavioural colour preferences of birds (e. g. CURTlUS 1954; HESS 1956; TINBERGEN et al. 1962; KEAR 1964; QUINE and CULLEN 1964; HAILMAN 1967; OPPENHEIM 1968; DELlUS 1968). Several aspects of th...
متن کاملAccurate memory for colour but not pattern contrast in chicks
The visual displays of animals and plants often look dramatic and colourful to us, but what information do they convey to their intended, non-human, audience [1] [2]? One possibility is that stimulus values are judged accurately - so, for example, a female might choose a suitor if he displays a specific colour [3]. Alternatively, as for human advertising, displays may attract attention without ...
متن کاملDistinct behavioral phenotypes in ethanol-induced place preference are associated with different extinction and reinstatement but not behavioral sensitization responses
Conditioned place preference (CPP) is a model to study the role of drug conditioning properties. In outbred strains, individual variability may affect some behavioral measures. However, there are few studies focusing on understanding how different phenotypes of ethanol conditioned behavior may influence its extinction, reinstatement, and behavioral adaptation measures. We used male Swiss Webste...
متن کاملDifferential effects of specific carotenoids on oxidative damage and immune response of gull chicks.
Micronutrients are essential for normal metabolic processes during early development. Specifically, it has been suggested that diet-derived carotenoids can play a key role in physiological functions because of their antioxidant and immunostimulant properties. However, their role as antioxidants remains controversial. Additionally, it is also unclear whether oxidative stress mediates their immun...
