The purpose of this experiment was to explore the effects of emulsified oils on growth performance,serum biochemical indices and blood cell differential counts of weaned piglets.Eighty healthy 25-day-old"Du-rocxLandracexLarge"weaned piglets with an initial body weight of(8.43±0.32)kg were selected and ran-domly allocated into control group(adding 2％soybean oil to basal diet)and emulsified oil group(adding 2％emulsified oil to basal diet).Each group contained 4 replicates,and each replicate contained 10 piglets.The experiment lasted for 28 days.The results showed as follows:1)there were no significant differences in aver-age daily gain,average daily feed intake and feed to gain ratio of weaned piglets between 2 groups(P＞0.05).2)Compared with the control group,the serum total protein,albumin and uric acid contents and alkaline phos-phatase activity of emulsified oil group were significantly decreased(P＜0.05).3)Compared with the control group,the blood white blood cells,neutrophils and lymphocytes numbers and hemoglobin and mean corpuscu-lar hemoglobin concentrations of emulsified oil group were significantly increased(P＜0.05).In conclusion,dietary emulsified oil has no effect on growth performance of weaner piglets,but it may promote the body pro-tein catabolism and improve the body immune function.[Chinese Journal of Animal Nutrition,2024,36(11):6969-6976]
