	abstract = {Voluntary intake and liveweight gain of Angus cattle (CAP) and swamp  
buffalo (B) were compared on 2 feeds; <I>ad lib.</I>, lucerne hay (L) + 1 kg  
concentrate/animal/day (LC) and <I>ad lib.</I> pasture hay (P) in a 2 x 2 Latin   
square designed trial.  The two hays had similar ME values; L, 8.5 and P 8.7  
MJ/ME/kg DM, but differed (P<0.05) in protein content; L, 14.6\% and P  
10.1\%.  The concentrate was 13.5 MJ ME/kg DM and 14.1\% protein.  Animals  
were fed in a feed-lot with individual pens/treatment.  Intake was assessed 
on a group basis for all treatments and individual animal intake was assessed 
for the P treatments only using slow release chromium capsules.  Two, 4 week  
experimental periods were preceded by a 2 week feed adjustment period. 
 
Liveweight gains showed a species x fed interaction (P<0.001) with individual  
treatment gains (kg/day) of; 0.80, -0.54, -0.02, -0.09 for CLC, CP, BLC, and  
BP groups respectively.  Cattle consumed (group assessment) more (P<0.05) L  
Hay than buffalo; 127 vs 99 g DM/kg LWT0.75.  The intake of P hay was  
similar for each species; 102 and 100 g DM/kg LWT0.75 for C and B  
respectively.  The release of CR2O3 from the capsules were similar for the two  
species (1.56 g/day).  Intakes of P hay assessed by the marker techniques  
differed (P<0.05); 100 and 88 g DM/kg LWT0.75 for the CP and BP treatments  
respectively. 
 
The difference in performance of the two species on P may have been the result  
of the marginal (for cattle) protein levels.  No explanation is given for the 
poor performance of buffalo on the LC ration.
