SUMMARY

Eighteen cross-bred heifers (with an average body weight 63.2 kg) were used in an experiment to study the effects of feeding pioneer 988 alone or supplemented with either legume forage or a concentrate ration, on the feed intake and growth rate of heifers. Treatments were; A, pioneer 988 only (basal diet); B, pioneer 988 + Clitoria ternata and; C, pioneer 099 + concentrate ration. The average liveweight gains of the heifers were 0.18, 0.30 and 0.61 kg/head/day (SE±1.5) for treatment A, B and C respectively. The corresponding feed dry matter were 2.89, 3.20 and 3.52 kg/head/day (SE ± 0.27) . Heifer liveweight gains were significantly (P < 0.01) affected by the supplementation offered to the basal diet. Within the supplement treatments heifers fed concentrates have grown significantly (P < 0.01) more than heifers fed forage and legume supplement.
