The objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of ten pasture forage species dominant in the west provinces of Iran. Duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. The chemical com...
this study was conducted to investigate the effects of doses of 25, 50 and 75 kgy of gamma ray (gr) and electron beam (eb) ionizing radiations on ruminal disappearance of amino acids (aas) and protein subunits of canola meal (cm). the nylon bag technique was used for degradability trial. three ruminally fistulated taleshi bulls were used for this aim. the disappearance trends of protein subunit...
Copper (Cu) is essential for the health of livestock, however, optimal source and level dietary Cu yaks are uncertain. To fill this important gap, we designed an in vitro study to examine effects three sources, namely methionine (Met-Cu), chloride (CuCl2) tribasic (TBCC), at five levels, 5, 10, 15, 20 25 mg/kg DM (includes substrate), on rumen fermentation yaks. In dry matter degradability (IVD...
This study aims to evaluate the nutritive value of Ajuga iva (A. iva) harvested from three distinct altitude regions in Tunisia (Dougga, Mograne, and Nabeul). The chemical composition, phenolic concentration, gas production, vitro dry matter (DM) digestibility were determined. highest concentrations neutral detergent fiber (NDF) acid (ADF) for A. cultivated Nabeul. In contrast, crude protein (C...
In order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, Ross 308 strain. Poultry by-product meal was prepared from two slaughter house in Alborz province. Samples were sent to laboratory for determination of chemical analysis. The birds received commercial broiler starter...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
Due to the extensive area and biodiversity, rangelands contribute to meeting the nutritional requirements of grazing livestock; Therefore, a study was conducted to investigate the nutritional value of four range species including Malcolmia africana, Plantago lanceolata, Phlomis cancellata, and Klasea latifolia in the mountainous rangelands of Torbat-e Jam. The sampling of plants was randomly do...
