The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

in this study, the role of soil properties in making difference between plant communitieswas examined. first, four plant types were identified, including pteropyrumaucheri-salsolarigida، astragalus gossypinus - acanthophyllum herateens، amygdalus scoparia – achilla millefolium and ephedra intermedia – erigon capestra, through randomized systematic sampling and field survey in representative are...

A method for direct measurcmcnt of percentage of assimilation of organic matter by zooplankton that does not require the quantitative recovery of feces and can be adapted for USC in the field as well as in laboratory investigations is described. If it is assumed that only the organic fraction of the food ingested by a zooplankton animal is affected by the digestive process, it can be shown that...

The nutritive values of non-processed and processed pistachio peel with Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis. An in vitro digestibility study was done to determine digestibility coefficients of dry matter (DM), organic matter (OM). Digestible organic matter in the dry matter (DOMD) to estimate the metabolizable energy (ME)...

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35 ́N) in 1999–2001. The dry matter yield and leaf to stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibil...

One of the main factors of water erosion is the natural characteristics of the soil called "erodibility" or"detachability". The present study aims to analyze the variations of soil erodibility factor in different plains and thefactors related to it. Erodibility is one the key factors in some models of erosion and sediment such as Universal SoilLoss Equation (USLE), Revised USLE (RUSLE), and Mod...

Organic farming is an agricultural practice that raises plants especially vegetables and fruits without the use of synthetic pesticides, herbicides, fertilizers, or plant growth regulators. All over the world, the interest for organic farming has increased recently. Different greenhouse experiments were carried out in the northern Jordan Valley, to compare the effect of four fermented organic m...
