Apparent Nutrient Digestibility Assessment and Influence of Gelatinized and Non-gelatinized Corn Starch Based Diet in Labeo rohita

Farkhanda Asad,Mahwish Qamer*,Nimra Tahir

Gelatinized and non-gelatinized corn starch based diet was processed at varying protein levels for apparent
nutrient (dry matter, ash, crude fat, crude protein and gross energy) digestibility coefficient (ADC) evaluation in Labeo rohita. For a tryout of 120 days, six semi purified diets were assembled (T1: G, 30% CP; T2: NG, 30% CP; T3: G, 35% CP; T4: NG, 35% CP; T5: G, 40% CP and T6: NG, 40% CP) in which two replicates were followed for each diet. Chromic oxide was added being an indigestible marker. Apparent dry matter, crude fat and gross energy digestibility was best exhibited by T6 (12.00%, 79.60% and 32.10%) compared to other test diets while apparent protein digestibility was observed maximum in T2 (67.70%) followed by T1 (65.40%), T6 (52.60%), T5 (40.00%), T4 (32.60%) and T3 (20.20%) respectively depicting non-significant variations. In case of ash, the apparent nutrient digestibility was capital in T4 (18.60 %) comparing others diets where the values being non-significantly different are T3 (13.40%), T1 (13.30%), T6 (12.70%), T5 (12.30%) and T2 (9.79%) respectively. The described outcomes revealed that Labeo rohita may be able to utilize the non-gelatinized corn starch based diet more efficiently and being economical it spares the protein based cost effective feed.
