this study was conducted to evaluate the effects of inoculation of homo-fermentative lactic acid bacteria(lab) on ensiling characteristics and nutritive value of low dry matter corn silage (ldmcs). corn foragewas harvested at milk stage (22.8 ± 0.9% dm), chopped at theoretical length of cut (tlc) 2.5 cm, and stored in eighteen 3.8 l mini silos for each treatment. the following treatments were u...

a study was conducted to evaluate the effects of plant growth promoting rhizobacteria (pgpr) inoculants including four strains of azotobacter chroococcum, azospirillum lipoferum, a. brasilense and pseudomonas fluorescence on dry matter accumulation of late maturing maize(zea mays l.) hybrids, sc704, sc700 and a promising single cross b73×k18. a factorial experiment was conducted in research fie...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

Lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. Mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were 5.30%, 1.55%, 29.20%, sheep 3.00%, 0.83%, 27.90%, and goats 2.910%, 1.55% and 28.40%, respec...

degradation of dry matter (dm) and nitrogen (n) in fresh or frozen-thawed alfalfa and ryegrass was studied by using in situ technique. the forages were labeled with 15n during growth in a glasshouse, harvested at similar growth phase, and fresh (f) or frozen-thawed (ft) samples were incubated in the rumen of 3 sheep. there was no difference (p>0.05) between forage type (s) for the immediately s...

STORAGE AND FEEDING Each year more than 60 million acres of forage crops are harvested for hay in the United States. Annual production from this acreage is over 150 million tons of hay valued at more than 12 billion dollars. Hay is the most widely grown mechanically-harvested agronomic crop in the United States. As a source of nutrition for livestock, hay offers numerous advantages. It can be m...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...
