The results suggest that cross-slope walking requires functional musculoskeletal adaptations that may be difficult for animals with impaired locomotion.
In conditions where water is not a limiting factor for animal production, it could be difficult for animals to take enough fresh cactus to meet their requirements, as a level of water exceeding 780 g/kg fresh forage is claimed to have a detrimental effect on voluntary intake (John and Ulyatt, 1987, cited by Minson, 1990a).
As with human studies, however, it may be difficult for animal studies to distinguish those aspects of impulsivity that are predisposing for AUD phenotypes from those that develop concurrently with or as a result of the disorder.
It is important that model cohort studies should not employ animals that are greatly sickened either by genetic impairments, such as those produced by inbreeding and mutagenesis, or by poor experimental conditions, such as conditions in which it is difficult for animals to derive sufficient nutrition.
Given that it is difficult for animals to form the context-shock association if shock is delivered soon after animals are introduced to the context (a.k.a. immediate shock deficit (Fanselow, 1990)), freezing behavior during the re-exposure is mainly a reflection of the memory of the pre-exposed context, though the recall of shock context may also occur.
These adaptations may be difficult for geriatric animals, or those with orthopedic or neurological disorders.
The significance of the pathology may be viewed within the context of domestic goat ecology in the landscape of Jarmo, potentially impacting browsing behaviour (goats raise themselves on their hind limbs to browse) and movement with the herd in the landscape (the terrain around Jarmo is very steep in places, which would be difficult for an animal to navigate on three legs).
It would be difficult for the animal to adapt to the cold, as he's already accustomed to the climate in Mendoza".
The present study was also restricted to healthy Labrador Retrievers that were easily able to handle cross-slope walking, a task that would likely be difficult for orthopedically/neurologically impaired animals.
But Chris Heyde of the Society for Animal Protective Legislation, a Washington, D.C., group that lobbied for the bill, says it would be difficult for researchers to bring the animals out of retirement.
The twice-a-day regimen chronic treatment as might be expected can be difficult for the owners of uncooperative animals which has led to the development of transdermal options for drug administration.
