The in vitro energy and enteric methane values of three microalgae species for ruminants

Abstract

Objective: The aim of the study was to determine the in vitro energy and enteric methane values of the three microalgae (Spirulina platensis (SPTS), Chlorella vulgaris (CVGS) and Schizochytrium spp. (SSPP) species by in vitro Gas Production Technique. Materials and Method: The gas production (GP) of the microalgae were found based on 3, 6, 9, 12, 24, 48 and 72 hours incubation period. The IVOMD (In Vitro Organic Matter Digestibility), ME (Metabolic Energy) and NEL (Net Energy Lactation) values were calculated by using 24-hours gas production and some crude nutrient contents. The CH4VFA (Methane volatile fatty acids) were found from volatile fatty acids (VFA) profiles of 48-hours of incubation residues. Results: For each microalgae, the differences between the IVOMD and NEL values were significant (P<0.05). The differences between IVOMD and NEL values were similar in SPTS and CVGS which were significantly higher than SSPP (31.10 DM% , 1010 kcal/kg) (P<0.05). The ∑VFA and CH4 VFA were found to be highest in CVGS and similar to each other in SPTS and SSPP. Although the CH4VFA values of SPTS and SPSS were similar to each other, the CH4VFA value of SSPP (0.70 mol/mol VFA) was found to be the lowest. Conclusion: If it is produced economically, it may be recommended that CVGS can be used as an alternative feed source in ruminant nutrition due to high energy, crude protein and ∑VFA concentrations, while SPTS and SSPP can be used as feed additives due to their low ∑VFA and CH4VFA concentrations.
