the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...

Thirty two multiparous Holstein cows were used in a randomized block design to investigate the effects of feeding diets included two different source of nonfiber carbohydrate during the transition period on dry matter intake (DMI), lactational performance, blood metabolites and parturitional characteristics. Cows received total mixed rations containing either macaroni wastes(MW) or steam-flaked...

We studied the influence of enzyme supplementation (ES) of the diet and heat processing (HP) of barley on digestive traits and productive performance of broilers from 1 to 42 d of age. There were 6 diets arranged factorially with 2 doses (0 and 500 ppm) of a fungal enzyme complex with beta-glucanase and xylanase activity and 3 HP of barley (raw, micronized, and expanded). In addition, a control...

fifteen holstein male calves (416 ± 35 kg initial bw; mean ± sd) were employed in a replicated 3 × 3 latin square test to investigate the effect of partial replacement of barley grain by wheat factory sewage (wfs) within three 22-d periods including 16 d of adaptation and 6 d of data collection. the basal diet (wfs0) consisted of 42.5% (dm basis) barley grain, partially replaced with either 23....

Barley is a cereal grain that has demonstrated world-wide importance. Although generally considered an energy source, barley has more protein than other cereals commonly used in ruminant diets. Nutritional composition of barley can be affected by geographic location and climatic conditions. Varietal differences account for some of the differences observed in nutrient composition. However, it is...

the objective of this study was to investigate the effects of summer savory essential oil (sseo) with cereals (based on barley or corn) on performance, rumen volatile fatty acid concentrations and some blood parameters of west azerbaijan native kids. in a randomized complete block design with a 3×2 factorial (0, 200 and 400 mg/d of sseo × barley or corn grain based diets) arrangement with 6 rep...

To investigate the effects of synchronizing nonstructural carbohydrate (NSC) and protein degradation on intake and rumen microbial fermentation, four ruminally fistulated Holstein heifers (BW = 132.3 +/- 1.61 kg) fed high-concentrate diets were assigned to a 4 x 4 Latin square design with a 2 x 2 factorial arrangement of treatments studied in vivo and in vitro with a dual-flow continuous cultur...
