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 کاملNecrotic hepatitis due to Clostridium perfringens infection in newly hatched broiler chicks.
Multiple necrotic hepatitis lesions of 5 newly hatched broiler chicks in three flocks derived from two hatcheries were examined pathologically. The livers were brittle, and multiple yellowish or green foci were scattered on the surface and cut surface. The main histological finding was well demarcated multi-focal necrosis in the liver. Many Gram-positive large bacilli that reacted positively wi...
متن کاملFailure of viable nonculturable Campylobacter jejuni to colonize the cecum of newly hatched leghorn chicks.
Campylobacter jejuni cells entered the viable but nonculturable (VBNC) state upon suspension in sterile water. Cell viability was determined with tetrazolium violet. VBNC cells suspended in water for 7, 10, or 14 days were given, by gavage, to day-of-hatch leghorn chickens. The ceca of control and challenged birds were examined for the presence of campylobacteria by conventional microbiological...
