Effect of Cellulolytic Enzymes and Probiotics on Growth Performance of Broiler Rabbits

Administration of enzymes and Probiotics in fattening rabbits improved growth performance and reduced the morbidity and mortality rate. Apart from Probiotics, enzymes are most important protein molecules which catalyze and improve acceleration of feed digestion. Therefore, keeping the above points in view the present study was undertaken to study the effect of enzymes and probiotics on body weight gain, feed efficiency and digestibil ity of nutrients. Thirty weaned heal thy broil er rabbits with comparable body weights were selected and randomly allotted into three dietary treatments (T1, T2 and T3) of 10 animals each.

The effect of enzymes and probiotics on growth performance of broiler rabbits was studied. During the 12^th weeks feeding trial, the cumulative daily weight gain of rabbits were 19.30 ± 2.52, 20.25 ± 2.46 and 19.70 ± 2.56 g/day/rabbit under T1, T2 and T3 respectiv el y. It was observ ed that there was significant (p < 0. 05) difference between enzyme and control group. The average weekly body weight gain recorded at the end of the trial (during 12^thweek) was 2097.5 ± 65, 2177.2 ± 77 and 2131.10 ± 70 g rabbit under Tl, T2 and T3 respectiv el y. It was observ ed that there was highl y significant (p < 0. 01) difference between enzyme and control group. Addition of enzymes hel ps in improv ing the body weight gain. Hence, can be added to rabbit feed.

The following recommendations can be made from the present study that enzyme and probiotics play a very important role in development of immunity against diseases.
