Impact of aluminosilicates on productivity, carcass traits, meat quality and jejunum morphology of broiler chickens

ABSTRACT The aim of the study was to compare production results and quality of meat, as well as histological features of the jejunum in broiler chickens administered feed with 1% addition of zeolite or halloysite, with the addition of aluminosilicates to litter ( 4,50 kg/m2) throughout the rearing. In the experiment, 300 male broilers were used for 6 weeks. They were divided into 3 groups, each of 10 repetitions (10 birds each). Group 1 was a control, in group 2 halloysite was added to feed and litter, while in group 3 zeolite was applied instead of halloysite. After rearing, 10 selected birds from each group were slaughtered. Selected production properties, degree of footpad dermatitis and histomorphometric examination of the jejunum was performed. The lowest yield and the highest proportion of neck with skin in the carcass were demonstrated in group 2 (P The addition of zeolite could be proposed because of the obtained production results, while the halloysite had a positive effect on the histomorphometric features of the jejunum.
