Use 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 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 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 کاملEffect 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 کاملDigestion of feed amino acids in the rumen and intestine of steers measured using a mobile nylon bag technique.
The disappearance of dry matter (DM), crude protein (CP), and amino acids (AA) in steers after rumen incubation and intestinal passage of alfalfa hay, barley hay, corn silage, barley grain, corn grain, wheat bran, meat meal, fish meal, cottonseed meal, and soybean meal were measured in 3 steers using a mobile nylon bag technique. Ruminal degradation of individual AA differed between feedstuffs....
