THE INFLUENCE OF NON STARCH POLYSACCHARIDES (NSP) CONTENT FROM FORAGES ON NUTRITIVE AND BIOPRODUCRIVE INDICES AT BROILER CHICKENS

Abstract

The NSP in cereal grains are composed predominantly of arabinoxylans (pentosans), beta glucans and cellulose. The main soluble NSP in these grains are arabinoxylans, while in barley and oats the are betaglucans. In this experiment we want to establish the influence of NSPs and NSPi from barley on nutritive and bioproductive indices at broiler chickens. The experiment was carried out on 120 broiler chickens divided in four experimental groups (CL, EL1, EL2 and EL3). The difference between the experimental groups was the different percentage of barley in the structure of combined forage and it was between 0 and 30% in the growth period from eclosion to 21 days and between 0 and 40% from 22 till 42 days of age. On the entire growth period the smallest forage consumption was registered by the control group, which had no barley in the structure of combined forage and registered the smallest values of NSPs and NSPi. The body weight at experimental groups was smaller with 3.25% but the differences were not statistical significant. In the growth period from 0-6 weeks in the experimental group EL1 the specific consumption is greater with 5.63% comparatively with the control group CL.
