| Abstract | ||
| The digestive enzyme roxazyme was added to local sunflower meal in order to improve the meal nutritive value for the broiler male parents (Fabrow) and enhance their productive performance. Five hundred male chicks were tested. They were randomly distributed on five nutritional treatments; each treatment was consisting of four replication (25 chicks / replication). All the chicks were fed, from one day to eight – week – ages, on two types of feed: a control feed devoiding of sunflower meal and feed containing a constant percentage (18%) of sunflower meal. The latter was divided into four subdivisions based on the amounts of the enzyme added to the sunflower meal. These four amounts were 0, 100, 150, and 200 grams of enzyme ton of feed. The statistical analysis (P<0.01) showed that the control treatment had significantly surpassed all other treatments concerning all productive performance characters including body weight, gain weight, feed consumption, and feed conversion coefficients. However, the addition for the digestive enzyme to the sunflower meal did improve the above mentioned characters ( depending upon the amount added ) compared with the meal devoiding of the enzyme although all these treatment dropped significantly behind the control treatment. | ||
