Effect of Pelagic Sargassum on In Vitro Dry Matter and Organic Matter Degradation, Gas Production, and Protozoa Population

This study determined the effect of pelagic Sargassum on in vitro dry matter and organic degradation, total gas production (TGP), protozoa population. The treatments were different levels inclusion a basal substrate (Stargrass hay; Cynodon nlemfuensis) as follows: T0 (control treatment based Stargrass hay), T10 (90% hay + 10% Sargassum), T20 (80% 20% T30 (70% 30% Sargassum). Ruminal fermentation kinetics population during 72 h incubations. Compared to control, degradability at 48 24 higher treatments. TGP was lower with h. concentration Entodinium spp. Cl, S, Ca, K, Zn (103, 5.97, 88.73, 285.70 g/kg, 15,900 mg/kg) high Sargassum, reaching twice or even nine times than contents (11.37, 1.60, 43.53, 87.73 866.67 mg/kg). Overall, up could be included hay-based substrates from tropical grasses without negative effects degradability.
