Open Journal of Animal Sciences 2013年第2期3卷 93-98页

作者： Essi evans david T. Mair Essi evans Technical Advisory Services Inc. Bowmanville Canada Jefo Nutrition Inc. Quebec Canada

Results from 4 switchback field trials involving 608 cows were combined to assess the effects of a protected B vitamin blend (BVB) vs 10 mg of unprotected biotin upon milk yield (kg), fat %, protein %, fat yield (kg) and protein yield (kg) in primiparous and multiparous cows. Trials consisted of 3 DHIA periods executed in the order control-test-control. Cows from 45 to 300 days in milk (DIM) at the start of the experiment that were available for all 3 periods were included in the analysis. No diet changes other than the substitution of 3 grams/cow/day of the BVB for 10 mg of biotin during the test period occurred. Results from the two control periods were compared to results obtained during the test period by individual cow using a paired T test. Results for all cows showed that the provision of the BVB resulted in increased (P ge (%), protein %, fat yield and protein yield. Analysis by age revealed that milk production and milk protein yield were only improved in mature cows. Milk production had a negative effect upon the magnitude of the increase in milk components. The change in milk yield was greatest in early lactation and declined with DIM. Protein % and fat % increased with DIM in mature cows, but not in first lactation cows. Differences in fat yields between test and control feeding periods did not change with DIM, but the improvement in protein yield in mature cows declined with DIM. These results indicate that the BVB provided economically important advantages throughout lactation beyond those witnessed with biotin, but expected results would vary with cow age and stage of lactation.

The Link Between Internet Financial Reporting and Information Asymmetry for American Depository Receipts

Journal of Modern Accounting and Auditing 2011年第9期7卷 947-965页

作者： Jocelyn evans david Henderson Brad Trinkle College of Charleston USA University of Mary Washington USA

We provide evidence on the effect of the presentation format and information content of Internet financial reporting on the market value of American Depository Receipts and on country-specific variables that drive Internet financial reporting. A two-stage Heckman approach was used to determine if Internet financial reporting adds incremental value to firms beyond the decision to cross-list in the United States. The results indicate that investors more highly value firms that provide information in multiple formats. We also find that country-specific variables affect the information content, but not the presentation format of disclosures on corporate websites. The results uncover a disconnection between what the market values （presentation format） and what the firms believe the market values （information content）. This implies that firms are not entirely aware of investors＇ information wants and that they are not utilizing their resources in the manner that will have the most impact on their market value.
