| Popis: | The present study aimed to evaluate in sacco fermentation kinetics of Moringa oleifera leaf meal (MOL), whole seeds (MOS), and partially (PDMM) or completely defatted seed meal (DMM). Four dry non-lactating cows (Holstein–Friesian cows, weighing 600 kg, 4 years old), with rumen cannula and T-cannula installed in the distal duodenum were used for the study. The cows were fed a mixed forage (17 kg maize silage and 4.5 kg alfalfa hay) and concentrate diet at 7:3, respectively. Samples were incubated in nylon bags (in sacco) for 3, 6, 9, 16 and 24 h. Proximate analysis showed that DMM and PDMM had greater concentrations of crude protein (CP) and fiber compared with MOL and MOS. Lower concentrations of condensed tannins were noted in both MOL and DMM compared to MOS and PDMM. Oleic acid was the most abundant fatty acid in both MOL and MOS. The Cornell Net Carbohydrate and Protein System analysis showed that MOL followed by MOS had more non-protein nitrogen; however, MOS and PDMM had more true soluble protein compared with MOL and DMM. Numerically, more intermediate and low degradable protein were observed with DMM. Results showed that MOL had the highest (P |
