Abstract

Improvement of the traits related to forage quality including Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and CP in forage species has a significant impact in increasing livestock production. In breeding programs that the number of samples is occasionally high, the use of chemical methods is time-consuming and costly. For this reason, NIR technology has been introduced as a rapid and accurate method in estimating chemical composition of agricultural products. This research was aimed to investigate the possibility of using this technology in estimation of NDF, ADF, and CP in three species of grasses. A total of 45 samples of each species were selected during different phenological growth stages and from different vegetation types. CP was measured by Kjeldahl method and Van Soest method was applied to measure NDF and ADF. For NIR calibration, samples were divided into two categories so that a part was considered for calibration and the rest for evaluating the accuracy of N
