Description	The influence of two temperatures (26+2°C and 37~C) and inoculation of 5% (w/w) pre-fermented silage as starter culture on hastening the process of fermentation of poultry intestine with 10% (w/w) molasses and 0"5% (v/w) propionic acid under micro- aerophilic condition was studied. The pH values, reducing sugar contents, standard plate counts, lactic acid bacteria and yeast and mould numbers were lower in mixtures fermented at 37~C than in those at 26 +_2°C. The microbiologically safe silage pH of 4"2 was reached in 24, 6 and 5 h in samples fermented at 26+_2°C, 37~C, both without starter culture and at 37~C with starter culture, respectively. Correspondingly, the staphylococci and enterococci were absent in samples at 48, 24 and 12 h onwards and coliforms and Escherichia coli at 48, 12, and 12 h onwards. Thus, the ensiling of poultry intestine with 10% (w/w) molasses and 0"5% (v/w) propionic acid was consider- ably accelerated by inoculating with 5% (w/w) prefer- mented silage as starter culture and fermenting at 37~C required 48-72 h to make the silage product free from pathogens. This longer ensiling time incurs greater cost. The optimum temperature for the multiplication of many bacteria is 37°C (APHA, 1984). The fermented PI silage contained high numbers (9-101ogcfu/g) of lactic acid bacteria (Shaw et al., 1997).The present study was designed to determine the effect of higher temperature (37°C) and the use of prefermented silage as a lactic culture to enhance the rate of fermentation.
