Dr. DeHaven said inspectors tested animals that were twitching, aggressive, nervous, stumbling or showing other signs of brain damage; they also test some dead or unconscious animals, which are not supposed to be sold for food.
By contrast, little is known about the perceptual correlates of gap-in-sound processing in ferrets, apart from a single study comprising two comprehensively tested animals that displayed heterogeneous performance (Kelly, Rooney, & Phillips, 1996).
It may be of benefit to human health and, ultimately, also to the welfare of test animals that might otherwise be required to prove the same findings, if these results are not published as part of the scientific record.
Using the rota rod, the tight rope and the corner turn test, animals that had received systemic injection of NPCs on day 0 or on day 1 showed better functional outcome than controls.
We observed a trend in our test animals that female rabbits exhibited stronger bispecific antibody responses than males.
The resulting serum levels for nonpregnant test animals that received implanted capsules for 2 weeks ranged from 2.2 to 3.3 ng/mL unconjuated dBPA, within the range (0.5 22.3 ng/mL) measured in humans (Padmanabhan et al. 2008).
We wish to stress that for Experiment 2, a second group of naïve rats were used (rather than testing the animals that already learned the tasks in Experiment 1).
In experiments, food-related odors are generally tested with starved animals, sex odors are tested with animals that are sexually aroused, and egg laying is tested with animals that have copulated.
