the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...
Alfalfa silages from 2 similar trials were analyzed for in vitro ruminal gas production. In both trials, there were 15 treatments: alfalfa treated at ensiling with 1 of 14 lactic acid bacterial inoculants or untreated alfalfa. First-cut (477 g of dry matter/kg) and second-cut (393 g of dry matter/kg) alfalfa were ensiled in glass jars for a minimum of 35 d at room temperature (approximately 22 ...
Five feeding studies were conducted with 141 lactating Holstein cows comparing macerated and control alfalfa silage harvested at two cuttings in each of 2 yr. Overall, silage made from macerated alfalfa contained more ash (suggesting improved soil contamination); greater fiber and lower nonprotein nitrogen (NPN) content suggested greater fermentation in the silo. In a digestion study, two diets...
This experiment was conducted to investigate the effects of flaxseed essential oil (0, 60 or 120 mg/kg) on chemical composition, aerobic stability, and in vitro gas production of alfalfa silage. Experimental treatments include: alfalfa treatment without additive (control), alfalfa with 60 mg/kg flaxseed oil and alfalfa with 120 mg/kg flaxseed essential oil, which were kept at room tempe...
Whole-plant corn was harvested at early dent, quarter milkline, two-thirds milkline, and black layer stages to evaluate the effects of maturity on intake, digestion, and milk production when corn was fed as silage in the diet. Twenty multiparous Holstein cows were used in a replicated experiment with a 4 x 4 Latin square design with 28-d periods. Diets containing 50% forage (67% corn silage and...
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...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
introduction this study was conducted to evaluate the effect of essential oils of oregano, sweet orange and cumin on chemical composition, parameters of gas production capacity, aerobic stability and degradability of dry matter corn silage carried. secondary metabolites such as essential oils have antimicrobial properties that by adjusting ruminal fermentation in ruminants to improve the use of...
McCartney, D. H. and Vaage, A. S. 1994. Comparative yield and feeding value of barley, oat and triticale silage. Can. J. Anim. Sci. 74: 91-96. The yield and feeding value of barley (Hordeum vulgare 'Johnson'), oat (Avena sativa 'Calibre') and triticale (Triticosecale 'Carmen') silages were compared in a field study, a heifer growth trial (1 19 d in length, with four pens of eight Charolais cros...
