Abstract

BackgroundFollowing the ban on the use of growth factors, the use of zeolite in poultry feed could be a solution to obtain healthier food products that are more demanded by the consumer.MethodsZeolite (Clinoptilolite) was added to turkey male and female feed at concentrations 1% or 2% and was evaluated for its effectiveness on performance of the production. The turkeys were given free and continuous access to a nutritionally non-limiting diet (in meal form) that was either a basal diet or a ‘Zeolite supplemented-diet’ (the basal diet supplemented with clinoptilolite at a level of 1% or 2%).ResultsIt was found that adding zeolite in the turkey diet had a positive effect on growth performance and increased weight gain compared to the control. In addition, zeolite treatment had a positive effect on oxidative stress and organoleptic parameters that were measured. It was found that adding zeolite in the turkey diet reduced the MDA level in the liver and in the meat, as compared to the control. Quality of meat was measured as a significantly increase (p < 0.05) in pH for male meat, indicated that the zeolite could maintain the quality of longer period. The adding of zeolite in the turkey diet increased level of polyunsaturated fatty acid.ConclusionThis study showed the significance of using zeolite, as a feed additive for turkey, as part of a comprehensive program to improve growth performance and oxidative stress parameters and to increase level of polyunsaturated fatty acid on the turkey body.

Highlights

Following the ban on the use of growth factors, the use of zeolite in poultry feed could be a solution to obtain healthier food products that are more demanded by the consumer
Clinoptilolite is a natural zeolite with a particular three-dimensional structure that endows it with specific physicochemical properties that include ion-exchange capacity, absorbency, size-exclusion framework, as well as catalytic properties [8, 9]
The objective of this study is so to examine the influence of natural zeolites, givens as supplement to feed turkey poults on growth performance, meat texture, oxidative stress and the fatty acid composition

Summary

Introduction

Following the ban on the use of growth factors, the use of zeolite in poultry feed could be a solution to obtain healthier food products that are more demanded by the consumer. The consumption of poultry products will be constantly increasing due to the expected evolution of the world population. For this reason, industries seek to improve production to cover this high consumption. Since the interdiction of the using of antibiotic in commercial poultry production, the use of essential oils and fed additives can improve the intake of compound foods [1,2,3,4,5,6]. Activated and micronized zeolites are detoxifying agents because of their selective binding of heavy metals, O2, and ROS. Various studies have shown that these hydrated aluminosilicates have no toxic effects in either humans or animals [10,11,12]. Activated and micronized zeolites are used as detoxifying agents in humans. Detoxification is attributed to their ability to reduce lipid peroxidation by scavenging free radicals [13]
