In order to investigating the effect of exogenous enzymes on growth performance, blood and rumen parametes,18 Brown Swiss male bulls were used in an balanced completely randomized design. The experimental diets were: 1) basal diet (control), 2) basal diet containing 0.50 g enzymatic mixture /kg DM of diet and 3) basal diet containing 0.75g enzymatic mixture /kg DM of diet. The bulls were fed to...

In order to evaluate grain yield potential and study dry matter remobilization to seed, 8 commercial bread wheat cultivars were examined in two separate experiments, using randomized complete block design with 4 replications in 2003. There were significant differences for most traits in normal and drought conditions. Sarday variety had the least grain yield in the two environments. There was c...

This research was conducted in order to investigate the effect of chemical and biological processing on the chemical composition, gas production parameters and in vitro digestibility of Cicer arietinum wastes in a completely randomized design (7 treatments and 3 replicates). Treatments were: unprocessed Cicer arietinum wastes (control) and processed with water (2.5 liter/kg DM), sodium hydroxid...

In order to evaluate the effects of planting methods and seeding rates on growth characteristics and yield of alfalfa (Medicago sativa L.), Hamedani cultivar, a field experiment was conducted in 2008 at College of Agriculture, Shiraz University, Iran. The experimental design was a completely randomized block with four replicates in a factorial arrangement of the treatments. The factors consiste...

Ephedra is a dioecious shrub belongs to the Ephedraceae family. Almost all commercial applications of Ephedra extracts is derived from the ephedrine alkaloids found in the evergreen stems. The purpose of this study was to investigate seed germination in green house condition and total alkaloid and ephedrine amounts measurement. The Ephedra seeds were collected from Bojnoord region and germinate...
