Summary

The relation between composition of food and numbers of rumen ciliates was examined in three buffaloes fed once a day. Depending on the diet and time after feeding, the total protozoa varied from 0·97 x 105 to 9·11 x 105/ml rumen fluid. Entodinia formed from 87·0 to 97·1%, Diplodinia from 1·9 to 11·4%, and Holotricha from 1·0 to 1·7%. The numbers of Entodinium, Polyplastron multivesiculatum and Holotricha were least in animals fed on hay only, while the smallest number of Anoplodinium denticulatum and Eudiplodinium maggii was found in buffaloes given a mixed diet containing 13·3% of concentrates. The highest number of protozoa was found in animals fed a mixed diet containing 26·9% of concentrates. No correlation was found between level of protein, crude fibre or nitrogen extracts in food and numbers of Entodinium, Polyplasstron and Holotricha in the rumen, but numbers of Anoplodinium denticulatum and Eudiplodinium maggii increased as protein content increased.
