Does supplemental zeolite (clinoptilolite) affect growth performance, meat texture, oxidative stress and production of polyunsaturated fatty acid of Turkey poults?

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.

Evaluation of the Effects of Pre-Slaughter High-Frequency Electrical Stunning Current Intensities on Lipid Oxidative Stability and Antioxidant Capacity in the Liver of Yangzhou Goose (Anser cygnoides domesticus)

“…Lipid oxidation is an important factor affecting the sensory and nutritional value, safety, and shelf life of animal products [19]. The MDA level is an important and significant biomarker of oxidative stress and lipid oxidation [7]. The effects of stunning methods on lipid oxidation in the liver of geese are shown in Table 2.…”

“…Lipid oxidation refers to the reactive oxygen species, which exceeds the ability of a system to neutralize and eliminate them [5]. Lipid oxidation can lead to unpleasant odors or tastes, color deteriorations, degradation in proteins, and decline in the shelf life of food [6,7]. The factors that affect lipid oxidation in poultry products include poultry diet, oxidative stresses in the live birds, pre-slaughter stunning methods, food processing methods, and storage conditions [8][9][10][11][12].…”

Dietary green tea powder supplementation enriched egg nutrients and physicochemical property in an indigenous chicken breed

“…Increased PUFA might decrease the hardness and thus promote improvements in the texture of the egg yolk. Although there have been no previous reports on egg texture changes by PUFA, research into meat quality has suggested that higher levels of PUFA increase its chewiness and meat texture ( Hcini et al., 2018 ).…”

Zeolites Applications in Veterinary Medicine

“…Also, clinoptilolite improve antioxidant capacity in broilers [74]; it is used as a feed additive in fish diets [75] and in turkey diets [76].…”
