The effects of feeding diets containing sunflower and wheat middlings pre-treated with fibre-degrading enzymes were investigated. Based on hatch body weight (BW), 288 Ross-708 male broiler chicks were placed in cages (six birds/cage). Diets were: 1) positive control (PC), a…
Exogenous enzymes and essential oils (EOs) have both improved fibre digestion in ruminants, but the effect on ruminal fermentation and methane emission of combining these additives requires further evaluation. Various EOs were used in combination with an enzyme in an…
Two experiments were conducted to determine the influence of sorghum variety and xylanase on performance of broiler chickens. In Experiment 1A, a total of 240 day-old Ross broiler chickens were assigned to a 2 (sex) × 3 (sorghum variety) ×…
A total of 360 65-week-old Lohmann LSL-Lite laying hens was used in a six-week experiment to examine the potential enhancing effects of a commercial carbohydrase preparation on phytase efficacy. Two cultivars of wheat (Marvdasht and Sardari) were used to formulate…
A trial was conducted to evaluate whether the addition of commercial enzyme preparations containing carbohydrases and a protease would increase the available metabolizable energy (ME) of maize-soya-based broiler diets. Seven thousand five hundred and sixty (7560) day-old Ross 788 chicks…
