(1) Six types of stoppers, each having different compositions, were cleaned with stainless-steel sipper tubes inserted into them and attached to polypropylene bottles filled with either deionized water (pH 4.5) or acidified-deionized water (pH 2.5).
(2) Eighteen enteral-fed male Sprague-Dawley rats had access to a standard hyperalimentation solution via a sipper tube ad libitum.
(3) Pine voles (Microtus pinetorum) were given sipper tubes containing saccharin solution, and after drinking, were injected with 0.15 M LiCl.
(4) We have worked tirelessly to share our gin of the highest quality with discerning sippers,” said Galsworthy.
(5) CFA was expressed in two-sipper tests, and during allogrooming of material from a cagemate's fur, but not during autogrooming.
(6) Also, in the absence of unique flavor cues, the rats learned to prefer, apparently based on somatosensory cues, the sipper tube that was paired with IG Polycose infusions.
(7) Subsequently, two-sipper tests were given to assure the presence of conditioned flavor avoidance (CFA), and then animals were presented with saccharin in carboxymethyl-cellulose on their own fur (autogrooming), or on the fur of cagemates (allogrooming).
(8) In contrast, only 1-3 days later when these animals are weaned, they strongly reject NaCl solutions from sipper tubes in favor of water.
(9) Group II received standard TPN solution orally from a bottle sipper and drank the solution ad libitum.
