A comparison among some growth promoters for fattening Egyptian Buffalo calves
Abstract: A total number of 80 male buffalo calves (about 12-13 mo.) were used to compare among the effect of pronifer, panacur and flavomycin supplementation in fattening buffalo calves rations as growth promoters on the productive performance and some carcass traits. Experimental animals were distributed into four groups (20 heads each) and were individually fed twice daily (2.5% of their LBW) on concentrate feed mixture without (CONT-group) or with pronifer (PRON-group) panacur (PANA-group) or flavomycin (FLAV-group). The calves were fed, also on restricted amount of green sorghum during the first month of the experiment and on rice straw (ad lib ).Before the end of the experiment, three animals of each group were subjected to determine nutrient digestibilities using grab sample method. Ten calves of each group were slaughtered at the end of the experiment.
The results show that growth rate was improved (p<0.05) by about 7.5% with panacur supplementation while there was sightly increase (p.>0.05) in growth rates when pronifer was added. In the same time, a negative response to flavomycin addition was recorded. Calves of FLAV group, consumed significantly (p<0.05) the lowest amount of DM. While those of PRON and PANA groups consumed the higher (p<0.05) amount than that of the control group.calves fed panacur –supplemented ration had significantly (p<0.05) the highest values of body gain related to the unit of DMI ,SEI,TDNI and DCPI being 114, 236,186 and 1804g LBW gain \kg ,respectively. While pronifer and flavomycin supplementation had no effect (p>0.05) on feed utilization. Values of in vivo digestibility of DM, OM and CP were slightly (p>0.05) improved by the supplementation of panacur, while it were not affected by either pronifer or flavomycin supplementation. However, the Cf digestion was improved significantly (p<0.05) by the flavomycin supplementation. Average amounts of boneless meat were 164.5,168.3,167.6 and 164.5 kg for CONT, PRON, PANA and FLAV groups, respectively. No significant differences were detected. Relative values of dressing percentage (as % of fasting empty body weight) were about similar (49.5,50.0,49.4 and 50.3%) meat: bone ratio was slightly (p>0.05) for calves fed on the three types of growth promoters than that of the control group.
