Egeria densa hay inclusion in ration for sheep
DOI: 10.1590/S1516-35982004000500024
Sixteen Santa Inês sheep were randomly allotted to four treatments (T0 = 81% tifton hay (TH) and 19% concentrate (soybean meal and corn); T27 = 27% egeria hay (EH), 54% TH and 19% concentrate; T81 = 81% EH and 19% concentrate) to evaluate the effect of Egeria hay inclusion in the diet on voluntary intake, weight gain and feed efficiency. Voluntary intake reduced and body weight gain was not affected by EH inclusion. During the experimental period, weight gain was similar for the animals fed diet without or with 27% EH. EH inclusion (at levels of 54 and 81%) affected quadractricaly body weight gain. Despite of the high minerals concentration, EH could be used as forage in small quantity or for short period.
