| Pellets is the only form used in the manufacture of commercial rabbit feed. But rabbit feed commercial production started late, varying of pellets quality. Molasses is a byproduct of sugar production industry. This paper studies the effects of different dietary ratio of molasses to rabbit pellet feed quality, production and related performance indicators. Test single factor randomized experimental design, add molasses preparation levels were 0%,2%,4%,8%of the diet, and then process pellet feed quality measurement.80 Iraq Rabbits of 40-days (male and female) were randomly divided into four groups, pretest of one week, the official of 30d. Feeding end of the trial, slaughter performance measurement, digestive tract development, digestive enzyme activity and other factories. The results are as follows:(1) molasses have a significant effect for pellet feed hardness (P<0.05), the hardness of which 4% dose group maximum (10.56kg), but 4% compared with the 8% difference was not significant (P> 0.05). Add molasses significantly reduced the rate of powder pellets (P<0.01), of which 8% of the lowest group. But no significant difference between 8% and 4% level group (P> 0.05). Add molasses containing powder particle feed rate impact was not significant (P= 0.0524).(2) With the addition of molasses to improve the level of Weakness gradually rise during the trial period on the 30th and feed ratio decreased significantly (P<0.05). Among them, the level of 8% of the highest weight group (650.8g), was significantly higher (P<0.05). And add a level to the weight difference between molasses proportional (P<0.05). Add 8% minimum level set ratio of feed (4.6), significantly lower than the control group (P<0.05), but no significant difference from other addition levels (P> 0.05). Molasses addition ratio is higher, the death rate of Amoy is lower. Add molasses had no significant effect on rabbit carcass dressing percentage (P> 0.05).(3) the length of the digestive tract, the relative weight of the various indicators of the impact of rabbit molasses development was not significant (P> 0.05), but there is a significant correlation (P= 0.0131) between this level and add the length of the small intestine. Molasses significant influence (P= 0.0147) on gastric chyme Operators degrees. Of rabbit blood glucose concentration, trypsin and cecum cellulase activity had no significant effect on molasses (P> 0.05), but adding cellulase activity level of the cecum and molasses show significant correlation (P= 0.0183).(4) of molasses rabbit cecum total bacteria, E. coli, lactic acid bacteria were not significant (P> 0.05), but the total number of bacteria, lactic acid bacteria with molasses added amount is increased and increased, and the proportion of added molasses There was a significant correlation (P= 0.039, P= 0.0438).(5) economic analysis shows that, in the range of 0% to 8%range, the addition of molasses, the higher economic efficiency.In conclusion, dietary molasses can significantly improve the hardness of the pellets, powder reduced rate. With the improvement of the level of molasses add significantly improve meat rabbit weight gain, reduced feed conversion ratio. Add molasses feed meat rabbit digestive tract development, digestive enzyme activity, had no significant effect on the number of cecal microflora. Comprehensive showed that under the experimental conditions, the optimal concentration of 8% molasses. |
