ABSTRACT
The present study involved in the determination of non-starch polysaccharides (NSP) of 15 wheat varieties and their in vitro and in vivo nutritional characteristics. The determination of in vitro viscosity, NSP, acid detergent fibre (ADF), neutral detergent fibre (NDF), crude protein and bushel weight were done for the samples of wheat varieties. There were significant differences between the samples of varieties in respect of these parameters. Especially, high correlations were estimated between the in vitro viscosity, NSP, ADF, NDF and bushel weight with regard to wheat varieties: For instance, the increased in vitro viscosity of 15 wheat varieties was associated with the increased ADF and NSP and the decreased bushel weight of wheat varieties. All the varieties were classified into 4 different groups according to their contents of NSP, bushel weight and in vitro viscosity. An animal digestibility trial was conducted with only one wheat variety from each of the four groups with broiler chickens from 14 d old to 42 d old. These varieties were Gun95, Cakmak79, Gerek79 and Kundura1149. Animals fed with all diets based on wheat varieties consumed significantly higher feed than the animals fed with a control diet based on corn grain. Especially, Gun95 and Cakmak79 varieties caused to increased feed intake compared with the other two varieties. All wheat based diets lead to significantly low weight gain, worsened feed conversion ratio, longer digestive tract and heavier digestive tract of animals in comparison with their counterpart of control diet. In addition, all wheat-based diets caused increased amount of abdominal fat and reduced carcass yield. On the other hand, there were some significant differences between the diets of wheat varieties in some of the above measured parameters. For instance, the lowest carcass yield was obtained from the Kundura1149, Gerek79, Cakmak79 and Gun95, respectively. Unlikely, the lowest abdominal fat was obtained from Gun95, Cakmak79, Gerek79 and Kundura1149, respectively. There were no significant differences in the digestibility of dry matter and crude protein between the wheat varieties. The NSP digestibility at both 21d old age and 42 d old age were numerically found to be higher for Gun95 and Cakmak79 varieties only. Some wheat varieties have a greater nutritional potential in both animal and human nutrition.
