Energy 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 کاملNewly hatched chicks solve the visual binding problem.
For an organism to perceive coherent and unified objects, its visual system must bind color and shape features into integrated color-shape representations in memory. However, the origins of this ability have not yet been established. To examine whether newborns can build an integrated representation of the first object they see, I raised newly hatched chicks (Gallus gallus) in controlled-rearin...
متن کاملThe Assessment of Cytokine and Antibody Responses to Recombinant 31kDa Brucella Cell-Surface Protein in Brucella Abortus Infected Mouse Model
Background & Objective: One of the most common diseases between zoonosis - especially in developing countries – is brucellosis. Identification of Brucella cell antigen combinations in terms of the amount and type of immune response in infected hosts, are important in vaccine design. 31kDa Brucella cell surface protein (BCSP31) is shared among all Brucellae. We aimed to define specific immune r...
متن کاملShort Copy Number Variations Potentially Associated with Tonic Immobility Responses in Newly Hatched Chicks
INTRODUCTION Tonic immobility (TI) is fear-induced freezing that animals may undergo when confronted by a threat. It is principally observed in prey species as defence mechanisms. In our preliminary research, we detected large inter-individual variations in the frequency and duration of freezing behavior among newly hatched domestic chicks (Gallus gallus). In this study we aim to identify the c...
