3 fistula sheep and nylon bag method(in situ) were used to measure the degradation rate of CP、ADF、NDF、ADL after Caragana hay,ammoniated Caragana,biochemically treated Caragana being fermented 6,12,24,36,48and 72 h in the cud.

This experiment measures the decomposing rates of the dry material (DM), organic material (OM), crude protein (cp), nonprotein organic material (NPOM) of pop corn in cattle rumen by applying nylon bag method.

The nutrient components and ruminal degradability of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) of 6 kinds of waste materials from fungal culture (WMFC) were analysed and measured by nylon bag method (in situ) in 4 adult goats installing rumen fistula in order to study the feeding value by using WMFC as feeds for ruminant.

Comparative study on nylon bag technique and feacal fluid method for determining organic matter and protein digestion;

Determination of the content and degradability of post rumen starch and rumen starch in ten kinds of feedstuffs by nylon bag technique

Nine Inner Mongolia semi-fine wool wethers fitted with rumen cannulas were used for the measurement of amounts of rumen bypass starch and degradability in corn starch,maize,wheat bran,soybean meal,flaxseed meal,cottonseed meal,alfalfa hay,grass hay,wild pea,corn stalks by in a nylon bag technique.

Six RPMet and four RPLys products were obtained and their stability were evaluated by in vitro and in situ methods.

crude protein (CP), (NDF) and (ADF) of 32 feedstuffs, fodder grasses and crop straws in rumen (from 2 to 72 h) were investigated using nylon bag (in situ).

In this paper, three local sheep fitted with permanent rumen cannula were used to investigate the effect of eliminating the rumen anaerobic fungi by fed chemical treated grass on fermentation in vitro and on dry matter loss in nylon bags of three roughage.
