NUTRITIONAL AND MICROBIAL STUDIES ON NANOPARTICLES IN BROILER DIETS

Abstract

The study included two experiments to determine the effect of different types and levels of nanoparticles (silver or graphene) supplemented in broilers diets and drinking water. First experiment Three hundred and sixty unsexed day-olds of Indian River (IR) broiler chicks were used to study the effect of using different types and levels of nanoparticles in broiler diets on performance, carcass characteristics, some bone traits, some blood components, length of the digestive tract and ceca and microbiological analysis of small intestine and cecum contents of broiler chicks. This experiment contained 9 treatments and 40 chicks for each treatment. The experiment lasted from 1 to 35 day-old and contained 3 treatments diets (starter, grower and finisher) contained 2.5, 5.0, 7.5, and 10.0 ppm/kg of both types of nanoparticles and control (basal diets) through the 3 different stages, respectively. The experimental period divided into 3 different stages; starter period, starting from 1 to 14 day-old, grower from 15-28 day-old and 29-35day-old, besides to overall period from 1 to 35day-old. All experimental traits and measurements have taken each period. Results of this experiment showed that 1. Productive performance including LBW, BWG, FI, PI and EPEF were differed significantly between treatments related to the different levels of nanoparticles but weren’t at affected by different types of nanoparticles overall period, also FCR wasn’t differed significantly by different types or levels of nanoparticles at overall period. 2. All carcass traits and cuts percentages haven’t affected significantly with different treatments except liver percentage was it increased significantly with increase nanoparticles level in diets.
