a determination of the effects of chemical treatment of two barley cultivars on ruminal dry matter and starch disappearance and on cncps carbohydrate fraction characteristics

چکیده
the objective of this study was to determine the effects of hulled and hull-less barley grains’ chemical treatment on disappearance of dry matter (dm), starch and cncps carbohydrate fractions. for barley grain treatment, naoh, formaldehyde and urea were used at 35, 4 and 35 gr/kg dm respectively. three mature rams (one year old) of zel breed were rumen cannulated to calculate ruminal disappearance (percent) of dm and starch. incubation time of nylon bags were 0, 2, 4, 6, 8, 12, 24 and 48 hours. to evaluate cncps carbohydrate fraction characteristics, its parameters were measured. rumen content disappearance results indicated that nao¬¬¬¬h and formaldehyde treatment had protective effect on dm and starch from rumen digestion leading to better results rather than urea treatment and control groups. also, starch disappearance of hulled barley was lower than hull-less barley (p
