production of halophyte plants with saline water and soil and feeding them to livestock is one of the most sustainable methods of conservation in desert ecosystem regions. kochia is a high salt resistant plant that can widely use as forage for livestock in arid ecosystems with lack of appropriate water and soil resources. in order to investigate potential of forage production of five different ...

this research was conducted to investigate the effects of fennel by product (fbp) on productive performance of growing lamb and in vitro gas production parameters, using 20 afshari×chal male lambs (bw = 49 ± 0.24 kg) were used in a randomized complete block design. experimental treatments consisted of diets including of 0, 3, 6 and 9% of fbp (dry matter basis). dietary treatments had no effect ...

the objective of the present field experiment was to examine how plant density and enhanced source, i.e. thinning treatments, may affect grain yield and its components for a non-prolific maize hybrid, sc704. the environment of the hybrid maize crop was changed at intervals over its life cycle by removing every other plant in rows equispaced at 75 cm apart with a population of 13.34 plants m...

to study the chemical composition and qualitative comparison of the pistachio by-products and the effect of pistachio hull tannin on its digestibility and gas production, four experiments were carried out. in the first experiment, nutrient composition, phenolic and tannin components of the ohadi, kaleghuchi and white varieties of pistachio by-product from dehulling process were measured. pistac...

Crop management practices (tillage, residue management, fertilization, etc.) define the soil environment to which crops are exposed and through these environmental conditions control crop growth. The purpose of this paper is to report the response of winter wheat (Triticum aestivum L.) to long-term (10 years) application of fallow tillage practices (plow, sub-till, and no-till) and N fertilizat...

and Implications An experiment was conducted with 48 laying hens to determine the effects of high dietary contents of corn dried distiller’s grains with solubles (DDGS) on nitrogen and dry matter manure excretion as well as egg production and egg quality. Diets containing 0, 23, 46, and 69% corn DDGS were fed to laying hens for 8 weeks after an initial 4-weeklong transition period during which ...

This research was carried out to evaluate the effects of flavone, myricetin, naringin, catechin, rutin, quercetin, and kaempferol at the concentration of 4.5% of the substrate (dry matter basis) on the rumen microbial activity in vitro. Mixture of guinea grass and concentrate (60 : 40) was used as the substrate. The results showed that all the flavonoids except naringin and quercetin significan...

Dry matter production data for pure lucerne, overdrilled lucerne and pasture ark presented for 14 sites on pumice soils. On average, the annual dry matter yield of lucerne, harvested at early basal shoot movement, was 50% higher than from pasture, ranging froti 128% higher on a drought-prone soil where the pasture was dominant browntop to 33% on a more moisture-retentive soil type where the pas...
