PERFORMANCE CHARACTERISTICS OF BROILER CHICKENS FED DIETS SUPPLEMENTED WITH CALCIUM PHOSPHATE NANOPARTICLES COATED WITH WILD SUNFLOWER LEAF EXTRACT

Résumé

Nanotechnology is one of the approaching techniques with the ability to increase global nourishment while improving dietary esteem, quality and security. This experiment was carried out to study the effect of diets containing Calcium Phosphate Nanoparticles on growth performance and nutrient digestibility of broiler chickens. Two hundred (200) day old Abor Acre strain of broiler chicks were weighed and randomly divided into 5 treatments of four replicates each. There were 10 birds per replicate making a total of forty (40) birds per treatment in a completely randomized design experiment. The birds in Treatment 1 were fed diets without the test ingredients (control), birds in Treatment 2, 3, 4 and 5 had control diet + 0.01%, 0.03, 0.05 and 0.07% of Calcium Phosphate Nanoparticles respectively. The experiment lasted for seven weeks. Result shows that Treatments 3, 4 and 5 had the highest final weight gain of 2244.09, 2216.14, 2249.97g respectively and the daily weight gain of 44.74, 55.03 and 45.03g. Treatments 1 and 2 had the highest daily feed intake of
81.06g and 80.94g respectively while the lowest feed intake (77.00g) was obtained in Treatment 2. The feed cost/kg weight in Treatment 1 (670.17g) was the highest and the lowest (597.81g) was in Treatment 5. It was concluded that feeding Calcium Phosphate Nanoparticles coated with Wild Sunflower leaf extract up to 0.07% inclusion level has no adverse effect on the growth performance of broiler chickens with 0.03% as the most recommended dosage for growth performance.
