Whne the above article was first published online, the body of text in Abstract (ASR-17-14) was a duplication of (ASR-17-13).
The correct body of the text for (ASR-17-14) should be:
Background: Swine are commonly utilized in research of the gastrointestinal tract (GIT), where unobstructed access to the upper or lower GIT is necessary for biomedical device evaluation. Studies may require the target area in the GIT be devoid of ingesta or that the animals receive nutrition via feeding tubes directly into the stomach rather than consumed per os. We regularly use a liquid diet developed by our facility, however, recent introduction of models to our institution studying the upper GIT has necessitated modifications to the liquid diet. Nestlé Benecalorie® is a low volume, high protein, calorie-dense, soluble supplement intended for people in need of concentrated nutrition. Our aims were threefold: (1) decrease the total volume of liquid diet fed to swine (intended to be administered via percutaneous endoscopic gastrostomy (PEG) tube), while maintaining caloric and nutritional requirements for growing animals; (2) provide a diet that was palatable, yet clear in color; and (3) remain cost-effective and efficient in terms of technician time for diet preparation and feeding.
Methods: Animals were sedated with Telazol (2.2 mg/kg IM) and maintained on isoflurane anesthesia (1-5%) for one of three procedures (esophageal implant, colon resection and anastomosis, or Nissan fundoplication). Liquid diet formulated to contain Benecalorie® was utilized in 3 different studies (2 evaluating the upper GIT and 1 looking at the lower GIT; n = 11 swine). Duration on diet ranged from 3 to 8 weeks, depending on the type of surgical procedure the animals underwent. Liquid diet was prepared in-house using commercially available ingredients, readily consumed by animals, and cost-effective for our institution in feeding large, growing animals long-term.
Results: Animals on all 3 studies maintained or gained weight compared with their own baseline body weights and against growth charts provided by the animal vendors from which they were acquired.
Conclusions: Animals on all 3 studies maintained or gained weight compared with their own baseline body weights and against growth charts provided by the animal vendors from which they were acquired. The use of Benecalorie® as a component of a liquid diet has significantly improved our ability to offer a calorie-dense diet in liquid form, and thus maintain positive animal welfare and nutritional status of growing swine, while ensuring study goals are met.
