Conteúdo: | The essential and non-essential amino acid profile of single-cell protein (SCP; Candida tropicalis) was higher than of groundnut-cake (GNC). Its crude protein content was 57.70% and fiber content nil. The digestibility coefficients of dry matter, organic matter, ADF [acid-detergent fiber] ether extract crude protein and NFE [N-free extract], respectively, were 74.40 .+-. 2.53, 76.23 .+-. 4.13, 58.43 .+-. 3.76, 70.16 .+-. 4.73, 74.27 .+-. 3.01 and 91.14 .+-. 1.57% in group fed GNC, and 71.39 .+-. 4.06, 73.69 .+-. 3.71, 51.08 .+-. 1.75, 61.33 .+-. 1.37, 72.11 .+-. 3.54 and 89.81 .+-. 1.67% in the SCP group. The variation in digestibilities of different nutrients between groups was non-significant. N balance was higher (P < 0.05) in the GNC group than in the SCP group. The average values of peak levels of NH3-N, non-NH3-N, total-N and TVFA at 2 h post-feeding was higher in the SCP group than in the GNC group. The difference between groups was significant (P < 0.05) only for total-N and TVFA [total volatile fatty acids]. The molar proportion of acetate, propionate and butyrate was similar in both groups. The acetate:propionate ratio was narrower in the SCP group than in the GNC group. SCP could be fed safely as a sole source of protein to the ruminants without affecting their general health, nutrient utilization and rumen fermentation.
