Abstract: This experiment was conducted to study the degradation characteristics of Moringa oleifera in the rumen of dairy cows and to explore the possibility of using Moringa as a feed resource for ruminants. Three dairy cows with permanent rumen fistula were selected to determine the disappearance rate and degradation parameters of Moringa leaves, branches, and stems. The disappearance rates and degradation parameters of DM (dry matter) and OM (organic matter) were nearly the same and reached a plateau at 48 h, while the degradation rates varied greatly among the different plant parts. At 96 h, Moringa leaves showed the highest disappearance rate (69.34%), followed by the branches and then the stems. The effective degradation rate of DM and OM differed significantly among the Moringa plant parts (P<0.05). The disappearance rate of CP (crude protein) of Moringa leaves was up to 90.86%, which was 22.84% and 38.92% higher than that of CP in the stems and branches, respectively. The effective degradability of CP was highest in the leaves, followed by the branches and then the stems, while the effective degradability of stem CP was higher than that of DM and OM. The rumen-degradable protein (RDP) content of Moringa leaves was up to 15.57%, and the contents of undegradable protein (RUP) were higher than that of RDP in the branches and stems. The disappearance rate was highest for the leaves, followed by the branches and then the stems (50.55%, 27.11%, and 41.43%, respectively). At 96 h, the disappearance rates of the branches and leaves were similar. The effective degradability of NDF (neutral detergent fiber) and ADF (acid detergent fiber) were significantly higher in Moringa leaves than in the stems and branches (P<0.05). In conclusion, the three parts could be ranked, from highest nutritional value to lowest, as follows: Moringa leaves>Moringa branches>Moringa stems. When feeding dairy cows, Moringa leaves should be individually fed, Moringa branches should be mixed with high nutrient content feed, while Moringa stems are not recommended as cow feed.
