ABSTRACT
A total of 200 26-day-old crossbred weaning piglets ((Yorkshire × Landrace) × Duroc; 6.55 ± 0.62 kg) were used in a 6-week experiment to evaluate the effects of adding probiotics complex supplementation (Syner-ZymeF10) with high and low ZnO diets on the performance of weaning pigs in 42 days. Pigs were randomly allotted to a 2 × 2 factorial arrangement and they were supplemented with two concentration level of ZnO with 3000 ppm and 300 ppm and probiotics complex supplementation with 0 and 0.1%. There were ten replicate pens per treatment with five pigs per pen (two gilts and three barrows). Pigs fed diets with 3000 ppm ZnO had a higher BW during the overall period and ADG during d 8-21, d 22-42, and overall period than pigs receiving 300 ppm ZnO diets (p < 0.05), as well as a G F which tended to increase on d 8-21 and overall period (p < 0.1) and decreased tendency on faecal gas emission of methyl mercaptans and acetic acid concentration (p < 0.1). Dietary probiotics complex supplementation had decreased the E. coli count (p < 0.05) and tended to increase the Lactobacillus count (p < 0.1). Dietary probiotics complex supplementation and different level of ZnO supplementation had no significant effect on the nutrition digestibility and faecal score (p > 0.05). In conclusion, probiotic supplementation reduced the fecal E. coli counts and tended to improve Lactobacillus counts. There were no interactive effects between ZnO and probiotic complex supplementation on all the measured parameters.
