Optimum zinc supplementation level in Nile tilapia Oreochromis niloticus juveniles diets
(Elsevier B.V., 2004-09-01)
The present study was designed to determine the optimum dietary zinc supplementation to Nile tilapia juveniles (13.3 +/- 1.13 g), by using vegetable-based diets supplemented with increasing levels of zinc from commercial-grade ...
Apparent absorption of zinc from supplemental inorganic and organic sources to Nile tilapia Oreochromis niloticus juveniles
(2005-09-01)
Nile tilapia Oreochromis niloticus fingerlings were fed with purified or practical diets, supplemented with 150 Ing Zn/kg, from different sources. Dry matter (DM), crude protein (CP), ether extract (EE), and gross energy ...
Dietary zinc deficiency predisposes mice to the development of preneoplastic lesions in chemically-induced hepatocarcinogenesis
(2016-10-01)
Although there is a concomitance of zinc deficiency and high incidence/mortality for hepatocellular carcinoma in certain human populations, there are no experimental studies investigating the modifying effects of zinc on ...
A 14-mo zinc-supplementation trial in apparently healthy chilean preschool children
(American Society for Nutrition, 1997)
Apparently healthy preschool children (46 boys, 52 girls) aged 27-50 mo from low socioeconomic conditions who attended daycare centers in Santiago participated in a 14-mo long double-blind zinc supplementation trial. Unlike ...
Relative bioavailability of zinc in supplemental inorganic and organic sources for Nile tilapia Oreochromis niloticus fingerlings
(2005-08-01)
A 90-day feeding experiment was conducted with sex reversed Nile tilapia (Oreochromis niloticus) fingerlings fed purified or practical diets supplemented with different zinc sources to evaluate fish growth performance and ...
Organic zinc supplementation modifies the metalloproteome of royal jelly produced by Apis mellifera
(2021-01-01)
In this study, we analyzed Apis mellifera royal jelly proteome alterations induced by supplementation with different concentrations of dietary organic zinc (0, 25, 50, and 75 ppm). Proteins extracted from royal jelly were ...
Zinc Supplementation Attenuates Cardiac Remodeling after Experimental Myocardial Infarction

High doses of inorganic zinc modulate the hypopharyngeal glands of Apis mellifera but promote abandonment of colonies when offered over long periods
(2022-06-01)
Previous studies by our research group verified the beneficial effects of zinc supplementation on honey bee colonies during offseason. Here, we used high concentrations of inorganic zinc to evaluate the effects of high ...
Supplementation with an Inorganic Zinc Source in the Metalloproteomic Profile of Royal Jelly in Apis mellifera L.
(2021-01-01)
This study aimed to evaluate the quality of royal jelly produced by honeybees Apis mellifera supplemented with different concentrations of inorganic zinc (zinc sulfate monohydrate—0, 25, 50, and 75 ppm). Two-dimensional ...
