Pigs were randomly allocated into 1 of 4 treatments according to their sex and BW (8 replicates with 2 gilts and 3 barrows per replication pen). Treatments were as follows: i) CON, basal diet, ii) TRT1, CON+0.1% Zn-ASP, iii) TRT2, CON+0.2% Zn-ASP, and iv) TRT3, CON+0.3% Zn-ASP. Pens were assigned in a randomized complete block design to compensate for known position effects in the experimental facility.Results: In the current study, BW, average daily gain, and gain:feed ratio showed significant improvement as dietary Zn-ASP increased (p&lt;0.05) in growing pigs. Apparent total tract digestibility (ATTD) of dry matter was increased linearly (p&lt;0.05) in pigs fed with Zn-ASP diets. A linear effect (p&lt;0.05) was detected for the Zn concentration in blood with the increasing levels of Zn-ASP supplementation. Lactic acid bacteria and coliform bacteria were affected linearly (p&lt;0.05) in pigs fed with Zn-ASP diets. However, no significant differences were observed in the ATTD of nitrogen, energy and Zn. And dietary Zn-ASP supplementation did not affect fecal ammonia, hydrogen sulfide and total mercaptans emissions in growing pigs.Conclusion: In conclusion, dietary supplementation with Zn-ASP of diet exerted beneficial effects on the growth performance, nutrient digestibility, blood profiles and fecal microbes in growing pigs.<\/jats:p>","DOI":"10.5713\/ajas.19.0057","type":"journal-article","created":{"date-parts":[[2019,7,1]],"date-time":"2019-07-01T03:54:26Z","timestamp":1561953266000},"page":"597-604","update-policy":"https:\/\/doi.org\/10.5713\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Changes
