Introduction: Tithonia diversifolia forage meal cv ICA Cuba Oc-10 constitutes an alternative to replace conventional foods (maize/soybean meals) in poultry diets.
Objective: To evaluate the inclusion of this alternative source in diets for broilers, laying hens and its replacements.
Methods: Chemical composition and the presence of secondary metabolites were determined. Physiological, blood chemistry, productive and economic indicators were evaluated. The inclusion levels were 0, 5, 10, 15 and 20% in EB34 broilers and 0, 15, 20 and 20% in L33 White Leghorn laying hens and its replacements. A completely random design with eight repetitions was utilized. Egg quality and quantitative morphometric indicators were analyzed by descriptive statistics.
Results: Inclusion of this variety in broilers diets (10%), laying hens (15%) and its replacements (20%) does not affect morphometric indicators of digestive organs of gastrointestinal tract, blood biochemistry and productive indicators. In layer replacements, inclusion of 20% caused an increase of width of the ileum intestinal villi (410 vs 169 սm). In broilers, its inclusion did not affect carcass yield, while in laying hens, egg quality remains unchanged, but an intensification yolk color was observed with the increment of this alternative food.
Conclusions: It is demonstrated the possibility to include Tithonia diversifolia cv ICA Oc.10 forage meal in broilers, laying hens and its replacements diets without affecting physiological, productive, blood chemistry and economic indicators.Downloads
