An Investigation on Nutrient and Selenium Content of Grass From Different Areas

Abstract

In this study, total nutrient and Selenium (Se) content of 84 pasture grass samples taken from 15 locations around Van Lake and were analyzed. The samples were collected every 15 days between May 15th 1996 and August 15th 1996 for seven different periods. Sampling was performed in 1 location for 3 periods, in 5 locations for 5 periods, in 7 locations for 6 periods and in 2 locations for 7 periods. The differences between periods were not significant in Crude Ash (CA%) (p>0.05) but were significant in Dry Matter (DM%), Crude Protein (CP%), Ether Extract (EE%), Crude Fiber (CF%) and Nitrogen Free Extract (NFE%) (p<0.05). There were significant differences between locations in DM, CP, EE, CA, CF and NFE% (p<0.05). Regression analysis results showed no relationship between DM, CP, EE, CA, CF and NFE% and Se (mg kg-1) content. © Medwell Journals, 2010.
