EFFECT OF FEED RESTRICTION WITH SUPPLEMENTATION OF PROBIOTIC ON PRODUCTIVE AND ECONOMICAL PERFORMANCE IN LOCAL GROWING RABBITS
The objective of this study was to investigate the effect of dietary different levels of feed restriction (FR) and probiotics (PR) (Lacobacillus lactis 2.5 x 108 CUF, Bacillus subtilis 1.8 x 109 CUF/g) on productive performance and economic efficiency for growing rabbits. A total number of 54 local growing rabbits,7 weeks old were weighed and divided into six dietary treatments of 9 rabbits each (5 males+4femals) The dietary levels of FR and PR included 3x2 factorial design as follow: T1: Rabbits fed basal diet ad-libitum without PR ,T2: Rabbits fed basal diet ad libitum and supplemented with 0.4g PR/ kg diet, T3 : Rabbits fed restricted diet by 120% of the energy requirements for maintenance without PR, T4: Rabbits fed restricted diet by 120% of the energy requirements for maintenance with 0.4g PR/kg diet, T5: Rabbits fed restricted diet by 140% of the energy requirements for maintenance without PR and T6: Rabbits fed restricted diet by 140% of the energy for maintenance with 0.4g PR/kg diet. The results illustrated that dietary ad-libitum with 0.4 g PR/kg diet were higher significantly (P≤0.05) live body weight than other treatment groups. But, the restricted diets120 or 140 % of the energy for maintenance with 0.4g PR/ kg diet did not significantly (P≥0.05) as compared to the control diet. The rabbits fed ad-libitum and supplemented with 0.4g PR/kg diet returned to the first position of daily weight gain and significantly (P≤0.05) exceeded the other treatment groups. Regarding feed conversion, rabbits fed 120% of energy for maintenance with or without PR and those received ad libitum diet with 0.4g PR /kg diet improved significantly (P≤0.05) as compared to control diet. All dietary treatments tend to have greater gastrointestinal tract and cecum% than control diet. Conversely, the rabbits fed different treatments had (P≤0.05) the lowest values of lipase and protease except for the restricted diet120% of energy for maintenance without PR as compared to the control diet. The best value of EE was found for rabbits fed 120% of the maintenance energy with 0.4g PR/kg diet. Conclusively, these results imply an important FR strategy by 120% of energy requirements for maintenance and supplemented with 0.4g PR/ kg diet, where feed conversion, performance index, E. coli /TBC ratio and economic efficiency improved under environmental Egyptian condition.
