Abstract

The aim of this research was to study the effect of adding enzyme preparations and ration formulation on performance, nutrient digestibility and intestinal microflora of Broilers. Two hundred and fifty six day-old male and female Broiler chicks of Ross 308 strain were used in a 2×2×2 factorial experiment consisting of two methods of diet formulation (total and digestible amino acid), two levels of Natuzyme Plus (0 and 0. 035%) and two levels of Multi-behzyme (0 and 0. 02%) as additives. The factors were arranged as a completely randomized design with eight treatments and four replications. Diet formulation based on total amino acids improved the average daily gain (ADG) and feed conversion ratio (FCR) during the grower and finisher and total periods, but decreased daily feed intake during the finisher and total periods (P ≤ 0. 05). It also increased dry matter digestibility, dressing percentage and intestinal length, but it decreased fat digestibility (P ≤ 0. 05). Natuzyme Plus increased dry matter, crude protein and fat digestibility and decreased the number of E. coli in the cecum. (P ≤ 0. 05). Multibehzyme improved ADG during the grower period, FCR during the finisher period and total period and it increased dry matter, crude protein and crude fat digestibility (P ≤ 0. 05). It was concluded that Multi-behzyme could be replaced with Natuzyme Plus, and its inclusion in the diets formulated by digestible amino acid and low protein content can improve the negative outcome of low level protein diets.
