The influence of restraint on the occurrence of oral sterotypies in dairy cows

Tethering of dairy cows induces high levels of behavioural disturbances [tongue-rolling, bar-biting], possibly triggered by frustrated feed manipulation. .. Five of six cows stopped performing stereotypies after the transfer into loose housing, while one cow which previously showed high stereotypy...

Setting guidelines for the care of reptiles, amphibians and fishes

Valuable, basic recommendations for the adequate housing of reptiles, amphibians and fishes. The following issues are briefly discussed: (1) Water; (2) Humidity; (3) Light; (4) Cage Furnishings The cage environment [of frogs] must remain constant if a male is to...

Effects of environmental enrichment and gentle handling on behaviour and fear responses of transported broilers

Enriched/handled birds were more active in their home pens than control animals. ..The most fearful birds were those which had been enriched [fabric squares, plastic rings, grass, perches, etc.] and handled, whilst the least fearful bird were enriched but not...

Cage enrichment for hamsters housed in suspended wire cages

Golden Syrian hamsters (n=99) were housed individually in suspended wire cages so that spilled food and excreta could be removed. After 8 days, the hamsters developed bizarre aggressive behavior which consisted of growling, hissing, aggressive posturing toward humans, destruction of...

Does maternal deprivation affect a calf’s physiological and behavioral reactions to later stress? Journal of Animal Science 70(Supplement 1), 162 (Abstract)

Calves separated from their dams at 21 days of age were found to show a significantly higher stress response [cortisol, heart rate] to later stress than those left with their dams until weaning.

Fetal and maternal body temperatures measured by radiotelemetry in near-term sheep during thermal stress

Using implanted radiotelemeters, we have measured amniotic temperature and fetal lamb and pregnant ewe body temperatures continuously over the last 34 days of gestation and during conditions of thermal stress. Body temperature of the fetus was approximately 0.6 degrees C...

Vibrissaeless mutant rats with a modular representation of innervated sinus hair follicules in the cerebral cortex

Specialized areas in the cerebral cortex are essential to mediate the various sensory modalities and are crucial to their recovery in disease. We recently observed that prenatal photoreceptor cues are not indispensable for the development of the elaborate modular organization...
