AI Article Synopsis
- A study was conducted on juvenile rats to examine how mercaptoacetate (MA) and lack of food affect their eating habits with chow and milk diets.
- It was found that MA increased the rats' chow intake but either decreased or had no impact on their milk consumption when both diets were available at the same time.
- On the other hand, depriving the rats of food overnight led to a boost in their intake of both diets, indicating that by 25 days old, they respond similarly to adults in relation to certain types of food stimuli.
Article Abstract
The effects of administration of mercaptoacetate (MA) and overnight food deprivation on intake of chow and milk diets were investigated in juvenile rats. In rats aged 25 or 30 days, administration of mercaptoacetate-stimulated intake of rat chow, while either suppressing intake or not affecting intake of milk diets. These effects were observed when each diet was presented individually, and when animals had both diets simultaneously. In contrast, overnight food deprivation led to enhanced intake of both diets, whether presented individually or available simultaneously. These results suggest that by 25 days of age, rats acquire an adult-like increase in food intake following lipoprivation by administration of MA. However, the effects of MA on intake in animals at these ages depends on the diet offered.
