Effect of predigestion factors on the apparent digestibility of protein for swine determined by the Mobile Nylon Bag Technique.
Five Yorkshire x Lacombe barrows (45 kg initial wt) fitted with duodenal cannulas approximately 10 cm from the pyloric sphincter were used to determine the influence of the pH of the predigestion solution (pH 1.0, 1.5, 2.0 or 2.5), pepsin activity (189 vs 377 IU/liter) and duration of predigestion (0, 1.5, 2.5 or 4.0 h) on the apparent digestibility of the protein in soybean meal (SBM), meal an...
متن کاملDetermination of undegradable intake protein digestibility of forages using the mobile nylon bag technique.
Two experiments were conducted using 2 ruminally and duodenally fistulated steers to determine the digestibility of undegradable intake protein (UIP) of smooth bromegrass (Bromis inermis), birdsfoot trefoil (Lotus coniculatus L.), and heat-treated alfalfa (Medicago sativa) using the mobile nylon bag technique. Undegradable intake protein was determined using neutral detergent insoluble CP at a ...
متن کاملUse of a nylon-bag technique for pig feed digestibility studies.
1. The use of a nylon-bag technique for pig feed digestibility determination was studied. Bags, measuring 25 x 40 mm and containing feed samples, were introduced into the pig gastrointestinal tract through a duodenal cannula, and recovered in the faeces between 23 and 69 h later. The disappearance of organic matter and crude protein (nitrogen x 6.25) from the bags was compared with in vivo appa...
متن کاملThe evaluation of the mobile nylon bag technique for determining the apparent protein digestibility in a wide variety of feedstuffs for pigs.
Studies were conducted with four (50 to 70 kg) barrows to evaluate the mobile nylon bag technique (MNBT) for determining the apparent protein digestibility (AD) in a variety of feedstuffs. One-gram samples of each feedstuff, ground through a 1.0-mm mesh screen, were enclosed in nylon bags (25 X 40 mm; 48 microns mesh). Following predigestion (.01 N HCl; 4,000 Folin Intestinal Pepsin Units/liter...
متن کاملRuminally undegradable protein content and digestibility for forages using the mobile bag in situ technique.
Four experiments were conducted to evaluate RUP content and digestibility for smooth bromegrass, subirrigated meadow, upland native range, and warm-season grasses. Samples were collected from esophageally cannulated cows or ruminally cannulated steers. Forages were ruminally incubated in in situ bags for durations of time based on 75% of total mean retention time, which was based on IVDMD and r...
