| Abstract/Description: | The growth performance and nutrient digestibility on rice polish based feeding regime with and withoutphytase was studied in crossbred (Hampshire × Ghunghroo) pigs. The trial was conducted in two phases. Inphase-I (Grower stage), four iso-nitrogenous (CP18%) diets were prepared by incorporating rice polish at 25and 50% supplemented with phytase @ 20 and 40g/100 kg feed, respectively. The same animals were used insecond phase for finisher trial. In phase II, animals were fed on four iso-nitrogenous (CP16%) diets prepared byincorporation of rice polish at 50 and 70% supplemented with phytase @ 20 and 40g/100kg feed, respectively.Growth was significantly higher (P<0.05) in pigs of grower phase which was fed on rice polish at 50% levelhaving phytase enzyme (40g/100kg feed) with better feed conversion ratio (FCR) and lowest (P<0.01) feedingcost of Rs 49.33±1.48 per kg gain in comparison to other three groups. Digestibility of DM, CP, P and energyvalues increased significantly (P<0.05) by increasing rice polish from 25 to 50% in diet. However, the levels ofinclusion of rice polish with different doses of phytase supplementation in finisher pigs during phase-II did notexhibit any significant effect on ADG, FCR and feeding cost in finisher pigs. The highest average daily gain(ADG) with better FCR and lower (P<0.05) feeding cost per kg gain was recorded in pigs fed on rice polish at50% level with 20g phytase/100 kg. Digestibility of protein decreased (P<0.05) significantly with increasing ricepolish from 50 to 70% in diet irrespective of phytase level. On the other hand, digestible energy valuesincreased (P<0.05) significantly by increasing the rice polish from 50 to 70% in diet. Hence, at maximum of 40gphytase (two lac unit/100kg feed) and 20g phytase (one lac unit/100kg feed) was sufficient for better growthperformance of crossbred grower and finisher pigs, respectively fed diets containing 50% rice polish |
