the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
This study was conducted to investigate the effect of formic and sulphuric acids on chemical composition, dry matter (DM) and crude protein (CP) degradability of alfalfa silage and its effect on early lactating Holstein cow as three trials. In the first trial, chopped alfalfa (22 and 33% DM) was ensiled with three levels of formic acid (0.0, 15 and 20 ml/kg DM) and two levels of sulphuric acid ...

A study was conducted with the objective to identify adaptable and chemical composition of Lablab varieties. Three Beresa-17, Gabis-55 Local variety +were tested in randomized complete block design (RCBD) three replications. The result revealed that date maturity significantly (p 0.05) differ among analyzed compositions indicated, Beresa-17 had highest Organic matter (OM), crude protein (CP), n...
the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...
Awareness of the forage nutritive value of rangeland species is important to provide a balanced diet in order to meet the nutritional requirements of ruminants and to determine the suitable grazing time and rangeland grazing capacity. Hence, different laboratory methods were used to compare the nutritional value of Centaurea cyanus, Fumaria officinalis, Galium tricornutum and Vicia sativa as co...
Four treatments were assigned to determine the effects of dietary potential digestible fiber (pdF) and crude protein (CP) levels in mid lactating Holstein cows on milk production and nitrogen efficiency. Sixteen primiparous (n=8) and multiparous (n=8) Holstein cows (body weight (BW)=546±72 kg; days in milk (DIM)=118±50 day) were allocated to one of four diets in balanced randomized complete des...
metabolizable protein (mp) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (rup) sources. effects on production efficiency and n utilization of early post-partum dairy cows were determined. forty-two multiparous and 16 primiparous holstein cows were assigned to the diets in a randomized complete block design immediately after part...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
