Abstract
In Tunisia, oats harvested as hay or silage is the forage the mostly used to feed cattle. Because of climatic conditions, it is generally cut at a period where its feeding value is low. The use of other green chopped forages in irrigated small farms could be an interesting alternative to provide good quality forage. The objective of the work was to study the nutritive value of alfalfa and sorghum at different vegetative stages. Six digestion trials were conducted using 10 Noire de Thibar breed sheep. Digestibility parameters were determined for 3 stages for alfalfa (bud, early bloom, late bloom) for 3 stages for sorghum (late vegetative, early bloom, dough). For each trial, the forage was fed ad libitum for 14 day adaptation and preliminary period and at 90% of maximum intake during a 7 day collection period. CP content of alfalfa were very high varying from 25.18% for bud stage to 16.8% for late bloom; where as the CP contents of sorghum were low varying from 9.25% for late vegetative stage to 5.2% for dough stage. Condensed tannin content was lower for the late vegetative (0.84 g/kg DM) compared to early bloom stage (1.1 g/kg DM) for sorghum. DM, OM, CF, NDF, ADF and CP digestibilities were different between the 3 stages for both forages.
