“…The physical parameter included pinna unfolding, incisor eruption, and eye opening (Sanches et al, 2019). The following behavioral reflexes were also assessed: righting reflex (the pups ware placed in the dorsal decubitus over a flat surface and observed the age that each pup returns from the prone position) (Anjos et al, 2022), negative geotaxis (pups were kept on a 45° inclined plane face‐down and observed the age that each pup was able to rotate at least 135°) (Ruhela et al, 2019), palmar grasp reflex (light pressure with a paper clip was applied until the pup showed a palmar grasp with the forepaw) (Laliberte et al, 2021), auditory startle (body retraction, with a transitory immobility in response to a sound stimulus) (Fragoso et al, 2017), and vibrissae placing (pup held by tail with head facing edge of bench with vibrissae just touching vertical surface and observed the lifting of the head and the extension of the forepaws in a direction of the bench) (Smart & Dobbing, 1971). On PND22, the offspring were weaned and distributed according to theirs sex and litter size and housed in groups of four per cage.…”
