“…The decline in crude protein concentration is also attributed to reduction in leaf to stem ratio with advancing age. These findings are consistent with previous studies (Sleugh et al, 2001;Sarwar and Nisa, 1999;Griffin and Jung, 1983;El-Shatnawi and Al-Qurran, 2003;Gupta and Sagar, 1987). The increase in the concentrations of NDF with increasing plant age is due to decreased leaf to stem ratio, synthesis of more cell wall contents and declined cell contents.…”

Four varieties of Tall fescue and three varieties of Setaria were analyzed for variation in chemical composition viz., dry matter, crude protein, neutral detergent fibre (NDF), acid detergent fibre (ADF), hemicellulose, oxalate content and in vitro dry matter digestibility (IVDMD) at different morphophysiological stages and clipping intervals. In Tall fescue the crude protein (11.81%) and IVDMD content (55.20%) were higher while NDF (63.65%), ADF (48.22%) and hemicellulose content (15.46%) were low during early growth stages. In Setaria the crude protein (10.92%) and IVDMD (62.34%) was high during early growth stages, but the same stages were also having high levels of oxalate (4.87%), which is one of the important anti-nutrient in Setaria associated with low milk production. With the advancing age there was decrease in the oxalate content in Setaria. The NDF, ADF and hemicellulose content increased with an increase in the age of plants. The results of the study revealed that to have balance among nutritive and anti-nutritive components Setaria should be harvested in the month of September and tall fescue in the month of March or April in mid hill Himalayan region.
