The purpose of this paper work was to establish the anti nutritive effect of non
starch polysaccharides from different protean sources on nutritive and
bioproductive indices at broiler chickens. The experiment was made on a period of
six weeks, on 120 broiler chickens divided in four experimental groups (EG1, EG2,
EG3 and EG4). Were formed four experimental groups: an experimental group EG1
fed with a forage at which the main protein source was soybean meal in proportion
of 34% in the period from 0 to 3 weeks and 30.5% in the period from 3 to 6 weeks,
an experimental group EG2 with high quality sunflower meal (36% CP) as protein
source in proportion of 10%, an experimental group EG3 at which was used poor
quality sunflower meal (27% CP) and an experimental group EG4 at which was
used peas in proportion of 15%. At the age of 3 and 6 weeks was determined the
nutritive and bioproductive indices. The highest forage consumption is registered at
EG4 at which in the structure of combined forage was incorporated peas and it was
with 8.69% greater comparative with EG1. The incorporation of poor quality
sunflower meal determines a decrease in body weight with 6.16% comparative with
the group at which was used soybean meal. The rising of NSPs and NSPt content
after incorporating poor quality sunflower meal determines the rising of specific
consumption at broiler chickens with 13.29% comparative with EG1 at which was
used high quality soybean meal.
