EFFECT OF ASPERGILLUS ORYZAE EXTRACT ON THE PERFORMANCE OF BALOCHI LAMBS

The effect of (Bospro®) an Aspergillusoryzae (A. oryzae) extract on the performance of Balochi lambs was studied at CASVAB, University of Balochistan, Pakistan during 2009. Lambs (n=20) were randomly selected, ear tagged and divided in to four groups comprising five lambs in each group. The trial was carried out for 12 week. Bospro® was given @ 30, 40 and 50 g/h/d mixed with the ration to groups A, B and C, respectively; while group D was treated as control. There was no significant difference in initial live body weight between groups (P 0.05). The results of the feeding trial over the twelve weeks period revealed that group B and C showed significantly higher weight gain (10.96±0.38kg and 10.51±0.56kg) and better FCR (4.04±0.20 and 3.85±0.14) respectively among all the groups (P 0.05). Group D exhibited least increase in body weight (6.78±0.24kg). Average daily gain for the groups A, B, C and D was (114.0±0.004, 125.0±0.007, 131.0±0.005 and 81.0± 0.22g) respectively. The results indicated the positive effect of the A. oryzae extract on the weight gain and feed conversion ratio of the Balochi lambs.
