Abstract


The objective of this experiment was to assess and fight against the NSP’s anti-nutritional effect from meat chickens’ alimentation. The experiment lasted for six weeks and was performed on a number of 120 chickens distributed in four experimental variants (LE1, LE2 and LE3, LE4). The hybrid used was Ross 308. We formed four experimental groups, as follows: the experimental group LE1 fed with a CF containing triticale in proportion of 40 % in its structure, the experimental group LE2 fed with a combined forage in which we had incorporated triticale in proportion of 60%, the experimental group LE3 fed with forage including triticale 60 % with supplementation of xylanase 100 ppm, and the experimental group LE4 fed with forage including triticale 60% and xylanase in a quantity of 250 ppm. We could observe that the NSPs, NSPi and NSP total contents increased with the increase of triticale participation; so, the combined forage including 60 % triticale during the growth period from eclosion to 6 weeks presented up to 1.08 percentage points the NSPs content, up to 0.28 p% the NSPi content and up to 1.36 p% the NSPt content. Xylanase incorporation in a quantity of 250 ppm determines body weight increase with up to approx. 12% in the case of 6-week old chickens and feed conversion ratio reduction with up to 10 %. The utilization of triticale in proportion of 40-60 % in combined forage structure, for broiler chickens, is possible only in association with enzyme incorporation; these determine the reduction of intestinal viscosity at duodenum and jejunum level, with up to 15 %.
