The objective of this study was to determine the chemical composition, in situ rumen Dry Matter (DMD) and Organic Matter Degradability (OMD48) of Apple tree leaves. In this study, Apple tree leaves were collected from the different parts of East Azerbaijan province. Chemical composition including Dry Matter (DM), Crude Protein (CP), crude Ash (Ash), ether extract, Neutral Detergent Fiber (NDF),...

The purpose of this study was to determine the effect of rumen inoculum from heifers with fast vs. slow rate of in situ fiber digestion on the fermentation of complex versus easily digested fiber sources in the forms of untreated and Ammonia Fiber Expansion (AFEX) treated barley straw, respectively, using an artificial rumen simulation technique (Rusitec). In situ fiber digestion was measured i...

In this study, nine male Dallagh sheep (initial weight 35±2 kg) were used in a replicated 3 × 3 latin square design experiment with three treatments and three 21-day periods (14 d adaptation, 7 d collection). Treatments were control (without addition) and two treatment diets containing 10% dry matter Glycyrrhiza glabra (licorice) and Urtica dioica (nettle) powder. The dry matt...

OBJECTIVE Two ex vivo experiments were conducted to verify the effect of barley grain (Nusrat cultivar) treated with alkaline compounds (AC) including alum, ammonium, and sodium hydroxide or cation-exchanged organic extracts (OE) prepared from alfalfa hay, sugar beet pulp and Ulva Fasciata, on extent and digestion of starch. METHODS In the first study, the in vitro first order disappearance k...

This study was conducted to compare digestibility of wheat straw (WS) by fungi and whole rumen microorganisms (WRM). Dry matter (DM), neutral and acid detergent fiber (NDF and ADF) digestibility of WS were compared with in vitro digestion (IVD), gas production (GP) and specific rumen anaerobic fungi culture (SRAFC). Dry matter, NDF and ADF digestibility of WS by WRM of buffalo (60.80, 49.93 and...

Dry matter intake, nitrogen intake, nitrogen digestibility, rumen ammonia-N and plasma urea-N concentration were measured in young rusa deer fed 4 diets containing 90 to 205 g/kg DM crude protein. The level of crude protein associated with maximal voluntary food intake and dry matter digestibility for these animals was found to be about 160 g/kg DM. Plasma urea-N was positively related to rumen...

A mechanistic and dynamic model was developed to represent the physiological aspects of liquid dynamics in the rumen and to quantitatively predict liquid flow out of the reticulorumen (RR). The model is composed of 2 inflows (water consumption and salivary secretion), one outflow (liquid flow through the reticulo-omasal orifice (ROO), and one in-and-out flow (liquid flux through the rumen wall)...

this study was conducted to investigate the effect of biological treatment withpleurotus floridafungi on chemical composition and rumen dry matter (dm) and organic matter (om) degradability of wheat and barley straw. wheat and barley straw were collected from golestan province of iran and after pasteurization mixed with fungi spawn (than 5% by weight). after 21 days samples were dried in oven (...
