Van soest and mineral analysis of wild buffaloes feces (Bubalus bubalis L.) in Savana Baluran National Park, East Java Indonesia

Abstract

Climate change has affected livestock production systems through impair feed intake, metabolic activities and defense mechanisms. Furthermore, it is also caused the greatest reduction of herbage yield and increase lignifications in plant tissues and hence decrease the digestibility of forage by the animal. The research has been done in Savana Bekol, Baluran National Park, East Java. The research was conducted in June 2019. Objectives: To know Van Soest analysis of wild buffaloes feces sample, so we know the type of plant that consumed. Methods: Observations were carried out by withdrawal feces sample with purposive sampling. Observation time is carried out for 8 hours (8.00-16.00). Van Soest analysis was conducted at Laboratory of Nutrition Technology of Animal Husbandry Faculty, Bogor Agricultural University. Results: The result for Van Soest analysis were Neutral Detergent Fiber (NDF) (71.60%), hemicellulose (23.19%), Acid Detergent Fiber (ADF) (48.41%), cellulose (2.22%) and lignin (32.91%). Mineral analysis showed that feces of buffaloes consists of Nitrogen Free Extract (NFE) (32.05%), Calsium (Ca) (2.00%), Phosfor (P) (0.52%), and Natrium Chloride (NaCl) (0.10%). Conclusion: These results indicate the NDF, hemicelluloses, cellulose of wild buffaloes were lower than pet buffaloes, but ADF and lignin of wild buffaloes were higher than pet buffaloes.
