Abstract

Understanding the NUTRITIONAL VALUE of the rangeland forage is essential for providing proper ratios that meet the nutritional needs of livestock. The purpose of this study was to evaluate the NUTRITIONAL VALUE of a number of plants in winter and summer rangelands of MANEH AND SEMALGHAN regions of Northern Khorasan Province in terms of meeting the needs of the livestock in the region. Accordingly, samples of a number of dominant species in the rangelands under study were collected at three phonological stages (i.e. vegetation, flowering, and seeding), following a completely randomized design (CRD). Afterwards, some of the most prominent NUTRITIONAL VALUE indices of the forage including crude protein (CP), metabolistic energy (ME), and dry matter digestibility (DMD) were determined and compared with the CRITICAL LEVELs. Generally speaking, the results of the study indicated that the livestock will not face any problems in terms of crude protein and dry matter digestibility in winter rangelands under study. However, regarding the metabolistic energy and except for the vegetation period, the livestock will probably face shortage and this may reduce livestock performance and consequently the income of the ranchers. Therefore, it is essential to use nutritious grains, forage, and energy supplements during this period. Livestock need regarding crude protein, metabolistic energy, and dry matter digestibility is supplied in summer rangelands during vegetation period. However, during the flowering and seeding periods, the livestock will probably face shortage. It is therefore necessary to carefully plan the feeding and use of nutritional supplements during these vegetation periods in an attempt to supply the livestock needs for the maintenance mode.
