Interaction of wheat cultivar and enzyme on broiler growth, nutrient utilization, and gut microflora.

This study examined the impacts of four wheat cultivars and enzyme supplementation on growth performance, nutrient digestibility, and ileal microbiota composition in broiler chickens. Six hundred forty-eight male broilers (1-day-old, Ross 308) were studied in a completely randomized design factorial 4 × 2 along with control (9 treatments) with 6 replications (12 birds per pen). The Diets consisted of the four varieties of wheat (Sardari, Azar2, Sirvan, and Pishgam) with and without enzyme supplementation, alongside a corn-based control diet.

Interactions of dietary wheat cultivars and NSP-degrading enzyme on productive performance and egg quality traits.

Context: The nutritional value of enzyme-supplemented wheat-contained diets can be influenced by interactions between wheat cultivar and exogenous enzyme, which in turn cause various effects on the performance of poultry.

Aims: The effects of diets including various wheat cultivars with or without enzyme on productive performance and egg quality characteristics were evaluated.

Methods: A total of 270 58-week-old Lohmann LSL-Lite were allocated to 9 experimental dietary groups with 5 replicate cages and 6 birds per each cage.
