Effects of Emulsified Oils on Growth Performance,Serum Biochemical Indices and Blood Cell Differential Counts of Weaned Piglets
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]
