| Summary : | The effects of free choice feeding (FCF) based on whole triticale on growth, meat quality, carcass characteristics, and digestive functions were investiga- ted. Eight hundred 1 day old Ross 308 broiler chickens were randomly divi- ded into 5 equal groups according to the dietary regimens: birds from the control group were fed with standard diets based on maize and soybean meal whereas in the other groups, free choice of triticale feeding starting since the 1st day (groups 2 and 3) or from the 21st day of age (groups 4 and 5) eventually coupled to dietary xylanase (1 g/kg of food) addition (groups 3 and 5) was also established. The highest body weight and weight gains, the lowest feed consumption and the best food efficiency were observed in the control group. Furthermore, carcass traits, meat quality and digestive functions were not negatively altered by free choice feeding with triticale and/or dietary enzyme inclusion. The results showed that broilers starting FCF at 1 day of age didn't prefer to eat whole cereal, and that xylanase supplementation had negative effect on growth especially in the starter period (from day 1 to day 21) and suggest that broilers do not select feed to maximize growth when offered free choice. |
