Evaluation of mobile nylon bag technique for determining apparent ileal digestibilities of protein and amino acids in growing pigs.
The mobile nylon bag technique (MNBT) may offer a simple, rapid means for assessing ileal AA digestibility of pig feed ingredients. In the present study, the effects of washing bags recovered from digesta, the amount and fineness of feeds, and feed trypsin inhibitor activity on apparent ileal digestibilities (AID) of CP and AA were determined with the MNBT. Twenty-four ileorectal anastomosed pi...
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 کاملThe Use of the Nylon Bag Technique for the Evaluation of Feedstuffs
The history of evaluation of the nutritive value of feedstuffs is reviewed, leading into a description of the development of the artificial fibre bag technique. me type of material and construction of the bag are described in detail and preparation of the samples and incubation times are also discussed. Applications of the technique to a study of the rumen processess; degradation of protein sup...
متن کاملDeveloping a Modified in vitro Gas Production Technique to Replace the Nylon Bag Method of Evaluating Protein Degradation of Alfalfa Hay in Ruminants
The present study was conducted to investigate the possibility of using a modified in vitro gas production technique in place of the nylon bag method to estimate protein degradability of alfalfa hay in ruminants. In the in situ experiment dacron bags were filled with 3 g alfalfa hay. This was incubated in the rumen of three ruminally cannulated Ghezel rams for the periods of 0, 2, 4, 8, 12, 16,...
متن کاملRuminal phosphorus availability from several feedstuffs measured by the nylon bag technique.
The present study was aimed at determining rumen phosphorus availability of some feedstuffs assessed with the nylon bag technique: forage (alfalfa), cereals (control-C wheat, formaldehyde treated-FT wheat, barley, corn), cereal by-products (wheat bran, wheat distillers, corn distillers) and meals (C and FT soya bean meals, rapeseed meals and sunflower meals). Rumen phosphorus availability was n...
