Variation of Rangeland Vegetation Characteristics According to Different Aspects

Abstract

This research was conducted to compare four different aspects of a natural rangeland in Ormanardı Village of Central district in Bingöl province, South East Anatolia for hay yield and quality. In this study; botanical composition by weight, hay yield, grazing capacity, crude protein (CP) ratio and yield, acid detergent insoluble fiber (ADF) ratio, neutral detergent insoluble fiber (NDF) ratio, dry matter consumption (DMC), digestible dry matter consumption (DDMC) and relative feed value (RFV) properties were investigated. According to the research, 67.5% of the botanical composition is composed of poaceous plants and 32.5% of the plants belonged to other families, while it is determined that there are no legume plants in the botanical composition. In the study, it was found that hay yield ranged between 23.2-129.3 kg da-1 according to rangeland aspects, and it was statistically significant in terms of hay yield values of rangeland aspects (p<0.01). Grazing capacity of the rangeland was calculated as 18.4 HB. Percent contributions of grasses and other family plants in the hay yield were 67.5% and 32.5%, respectively. As a results of research, CP yield and ratio, ADF, NDF, DMC, DDMC and RFV contents ranged between 2.3 to 16.7 kg da-1, 9.9 to 16.7%, 34.8 to 37.4%, 52.5 to 62.7%, 1.92 to 2.08%, 59.7 to 61.7% and between 91.8 to 109.4, respectively.
