“…Moreover, Surabhi et al (2018) noted that A. baumannii is a gut bacterium that has the ability to degrade cellulose. Santoso et al (2016) added Lactobacillus plantarum, Saccharomyces cerevisiae, A. baumannii and P. aeruginosa to the concentrate and observed enhanced fermentation and in vitro nutrient digestibility. Moreover, Santoso et al (2018) concluded that the additions of LAB, yeast, and cellulolytic bacteria to CFB altered in vitro patterns of ruminal fermentation by increasing the concentrations of ammonia nitrogen (NH 3 -N) and total VFAs and reducing the production of methane.…”

The research aimed at assessing the effects on nutrient digestion and ruminal fermentation by goats of a complete feed block (CFB) that incorporated agro-industrial by-products that were high in fibre and cellulolytic bacteria. Three Kacang goats, a native Indonesian breed, were used in a 3 × 3 Latin square experimental design with i) CFB without microbes (control), ii) CFB containing 1% Pseudomonas aeruginosa and 1% Acinetobacter baumannii, and iii) CFB containing 2% P. aeruginosa and 2% A. baumannii. Microbes in the CFBs consisted of lactic acid bacteria, yeast and cellulolytic bacteria that ranged from 106 to 108 cfu/g. The goats were fed each day at 08h00 and 16h00. The inclusion of P. aeruginosa and A. baumannii at 2% level reduced both neutral detergent fibre (NDF) and acid detergent fibre compared with other treatments. Goats fed on CFB with microbes had higher (P <0.01) digestibility of organic matter (OM) and NDF compared with control. The addition of P. aeruginosa and A. baumannii at 2% level increased (P <0.05) ruminal ammonia nitrogen (N-NH3), acetate, and total VFA. However, goats fed on CFB with microbes had lower (P <0.05) urinary N excretion, which improved (P <0.05) N retention compared with the control. It was concluded that a combination of lactic acid bacteria, yeast and cellulolytic bacteria in the CFB could modify fermentation in the rumen and increase the use of nitrogen in goats.
