Abstract

The present study was aimed at evaluating three tropical fodder grasses as a feed for water buffaloes. The evaluations were carried out at the Instituto de Zootecnia in Nova Odessa, São Paulo, Brazil using 12 Murrah water buffaloes with average initial weight of 209 kg. The animals were randomized and allocated to 3 paddocks of Marandu (Md), Setaria (St) and Tanzania (Tz). Data were collected over a 600-day period. Weight, height and thoracic circumference measurements were made monthly. Available dry matter (DM) and crude protein (CP) content were also recorded. Roughage showed that nutritive value is extremely variable throughout the year (P<0.01) Nevertheless Tz showed higher CP values (P<0.01). Animals grazing St gained less weight than the others. This can be seen by the equations Weight = 253.94 + 0.470 day-1 for Md; Weight = 248.16 + 0.446 day-1 for St and Weight = 257.87 + 0.491 day-1 for Tz Average daily gains were greater for Tz and Md. Regression analyses showed significant relations between live weight and thoracic circumference; live weight and height and between live weight and both variables with R2 of 0.865; 0.800 and 0.089 respectively.
