DIETARY EFFECT OF MIXED SAW DUST AS A SUBSTITUTE FOR WHEAT OFFAL ON INTERNAL ORGANS OF GROWER RABBIT FED EXPERIMENTAL DIET

Résumé

A total of 18 grower rabbits were allotted to 3 dietary groups of six (6) animals in a completely randomized design (CRD) to determine the dietary effect of mixed saw dust as a substitute for wheat offal on organ weight changes of grower rabbits. Each group was replicated thrice consisting of two animals per replicate. Sawdust was substituted with wheat offal at 0% 5% 10% respectively.   The result showed that they were significant (P<0.05) differences in the value of live weight, lungs and heart while there were no significant (P>0.05) differences in liver, kidney and testicle across the dietary treatments. However, the highest value of liver (1887) was recorded in diet 2 while the lowest live weight (1288g) was recorded in diet 3. The value obtained for liver, kidney and testicles followed a similar pattern across the dietary treatments. Rabbits on diet 1 recorded the highest value (1.15g) of lungs while the lowest value (0.70g) of lungs was recorded in diet 3 (10% substitution level). The highest (0.37g) of heart was recorded in diet 2 while the lowest value (0.23g) of heart was recorded in diet 3. The highest value of kidney (0.70g) and liver (3.77g) were recorded in diet 3  while the lowest value of kidney (0.60g) and liver (2.54g) were recorded in diet 1(control) and diet 2  respectively. It could be concluded that mixed sawdust is good alternative feed resources that could be effectively used in diet grower rabbits and at 10% conclusion level without adverse effect on the internal organs of the rabbit
