Abstract

This study was conducted to examine the chemical composition and nutrient DIGESTIBILITY of HAMADANIAN ALFALFA forage at different GROWTH STAGES on SANJABI SHEEP and Merghoze goat. Cultivars characteristics of alfalfa including, bush height, bush dry matter and their ratio were measured in four stages of growth (1- Budding time 2- Completed budding time 3-Early flowering time 4-Completed flowering time). Chemical compositions of samples after harvesting from each stages of maturity were measured by proximate analysis methods described by Weende. Nutrient DIGESTIBILITY coefficients of alfalfa were obtained by using four Sanjabi rams (42±2.1) and four Merghoze bucks (34±2.3) during spring in Kermanshah Province. Complete Random Design was used to compare data related to agronomic traits and chemical composition of alfalfa hay, Data related to DIGESTIBILITY were analyzed using Complete Random Design (switch back). The mean was compared using Duncan methods The mean of bush height, amount of dry matter and percentages of dry mater of fifty bushes in the budding time were 42±3.9 cm, 27±4.8g and 17.66±2.3 % respectively, whereas these parameters were 53,6±5.6 cm, 41.8±9.5 g and 23.1±2.6 % for completed flowering time, Crude protein at budding time compared with completed flowering time (21±1.6 vs. 16±1.9 %), which is in contrast with fiber percentages (21±1.1 vs, 24±0.9%). DIGESTIBILITY of dry matter (OM), crud protein (CP) and crud fiber (CF) at budding time were 63.5±2.1, 74.7±2.8 and 46.1±4.8 percent in sheep whereas these coefficients were 66.7±2.6, 76.4±3.1 and 48.1±4.1 percent in goat respectively. There was no significant difference on DM and CF DIGESTIBILITY at different stages. There were no significant differences between sheep and goat on DIGESTIBILITY except at complete flowering stage, which dry matter and crud protein DIGESTIBILITY were higher(p<0.5) in goat than those in sheep. It can be concluded that despite lower crop yield at budding stage, forage quality and nutrient DIGESTIBILITY was higher (p<0.5) than that at complete flowering stage.
