in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

Two experiments were conducted to establish a digestible energy (DE) content prediction model of rapeseed meal for growing-finishing pig based on rapeseed meal's chemical composition. In experiment 1, observed linear relationships between the determined DE content of 22 rapeseed meal calibration samples and proximate nutrients, gross energy (GE) and neutral detergent fiber (NDF) were used to de...

This study was conducted to examine the effect of different wheat straw and concentrate proportions on feed intake, nutrient digestibility, growth reproductive performances F1 cross breed (Boran X Friesian) dairy heifers. Wheat (WS) with 93% dry matter content chopped (3-5 cm in length) mixed concentrate, molasses water. The amount water used for preparation total ration three fold amount. Twel...

to determine the chemical compositions, minerals and in vitro digestibility lathyrus sativusstraw during three years in shahrekord, kohrang and lordegan climates in chaharmahal & bakhtiari. this was one of the important legume straws that farmers used in ruminant winter diets in south west of iran. this legume straw gathered of different climates for three years. all samples were chemically ana...

Correlations between concentrations of cell wall components (CWCs) in the leaf sheath and stalk and resistance to stalk tunneling by the European corn borer (ECB) [Ostrinia nubilalis (Hübner)] have been reported in some maize (Zea mays L.) populations. Evaluations of resistance to ECB stalk tunneling (ECB-ST) and concentrations of neutral detergent fi ber (NDF), acid detergent fi ber (ADF), and...

chemical composition and metabolizable energy of three camel browsed halophyte species (atriplex leucoclada, suaeda fruticosa, seidlitzia rosmarinus) were assessed and in vitro digestibility of dm (ivdmd), om (ivomd), ndf (ivndfd), adf (ivadfd) were determined using a completely randomized design. plant samples were collected based on camel's grazing patterns during the autumn-winter grazi...

background: excessive use of antibiotic growth promoters leaded in the creation of antibiotic-resistant bacteria and by consuming animal products, humans are at risk of receiving their residual. therefore, instead of using antibiotics as growth promoters, some alternatives must be identified and introduced to animal breeders. objectives: the purpose of this research was to study the effect of a...

This factorial study was carried out from 15/10/2020 to 31/6/2021 investigate the effect of chop length (CL) and level molasses (M) added at ensiling on chemical composition yellow corn stover including leaves stems. Those materials were chopped into 4 lengths, 5, 10, 15 20 mm as a source soluble carbohydrates 3 levels, 6, 8 10% dry matter (DM). Urea all samples 2% enhance nitrogen content. Sam...
