The Effect of Sodium Alginate-Coated Nano-Zinc Oxide on the Growth Performance, Serum Indexes and Fecal Microbial Structure of Weaned Piglets

Animals, Journal Year: 2023, Volume and Issue: 14(1), P. 146 - 146

High dose of zinc oxide (ZnO) could improve growth performance and alleviate disease status, whereas it caused serious environmental pollution bacterial resistance. This study was to investigate whether low doses sodium alginate-coated nano (saZnO), a new type resource, serve as potential alternative pharmacological traditional ZnO in weaned piglets. A total 144 crossbred piglets were randomly allocated into three groups, including basal diet without the addition Zn (CON), with 1600 mg Zn/kg from (ZnO), 500 saZnO (saZnO). The experiment lasted for 28 days. results showed that supplementing 14 days significantly improved body weight (BW) average daily gain (ADG) (p < 0.01) markedly reduced feed intake-to-gain ratio (F/G) 0.05) diarrhea rate. In addition, dietary increased activities antioxidant capacity (T-AOC) alkaline phosphatase (ALP) 0.01). Supplementing also promoted levels superoxide dismutase (SOD), IgM copper- zinc-containing (Cu/Zn-SOD) serum 0.05), decreased concentration malondialdehyde (MDA) indicating beneficial effect on immune functions.

Effect and mode of action of different doses and sources of zinc in weaning pigs using a meta-analytical and systematic review approach

Italian Journal of Animal Science, Journal Year: 2024, Volume and Issue: 23(1), P. 241 - 258

Published: Feb. 7, 2024

In the European Union, withdrawal of pharmaceutical zinc oxide (ZnO) poses challenges for post-weaning pigs management. The present work aims to elucidate, using a meta-analytical and systematic review approach, effects different doses forms (Zn) on health, performance, gut health weaning pigs. A total 309 articles were identified from literature research 2001 2021; 85 selected. Articles divided in 3 datasets evaluate: 1) ZnO (ZnO database); 2) efficacy infection models (challenge 3) effect Zn sources (special database). experimental groups classified according their dose: low (LZn: 0–200 ppm); medium (M1Zn: 201–630 ppm; M2Zn: 631–1600 high (HZn:>1601 ppm). Dataset 2 analysed by approach. Results showed that M1Zn M2Zn guarantee comparable average daily gain, villus height crypt depth HZn.
