in order to select and release of nassim, a new cultivar of red clover, the researcher carried out the researches at the field of seed and plant improvement institute (spii) in karaj and some research stations such as shahrekord, sanandej, kermanshah, arak, gorgan during years 1996-2006. the experimental research was carried out design rcbd with six treatments and four replications during years...

kochia scoparia is a salt resistant plant that can be used in producing forage in the areas with salt water and soil resources. one of the problems which produce the forage plants in these areas decreases the function and quality of the forage in irrigation condition with salt water. therefore, using the chemical fertilizers can be considered as a useful solution. this study was conducted to ev...

in this study, a new and valuable forage source was introduced with combination and silage of alfa-alfa, halocnemum and mesquite via chemical, gas production and in vivo methods. to perform this research, first the right amounts of the species were collected. then they were cut by chopper to the dimensions of less than 5 cm. then, halocnemum, mesquite fruit, alfalfa and molasses were silaged ac...

Three experiments were conducted to evaluate the effects of diet and monensin on performance, digestibility, and methane production in steers fed forage-based diets. In Exp. 1, 72 individually fed steers (300 ± 25 kg) were used in a randomized block design arranged as 2 separate 2 × 2 factorials with two common treatments, thus 6 diets were fed with 12 steers per treatment. Factors included hig...

plants cover composition, condition, trend, production, and grazing capacity of the rangeland change annually. in this research, the role of temporal rainfall distribution on rangeland production was assessed. this research had down in the rangelands of ilam (with semiarid to semi humid climate) and qom and markazi (with arid to semiarid climate) provinces. by attention on plant cover maps in e...

nutritive value of winterfat forage (eurotia ceratoides) was evaluated through chemical composition, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the cp, ndf, adf, ash, ee and nfc contents of winterfat forage was 19.4, 54.5, 41.6, 9.0, 1.4 and 15.7%, respectively. the leaves had highest cp (27.9%dm) and lowest ndf (40.7%dm)...
