Dibutyryl adenosine cyclophosphate (dbcAMP-Ca), an analog of cyclic adenosine monophosphate (cAMP), plays greater roles in regulating physiological activities and energy metabolism than cAMP. The aim of this study was to investigate the effect of oral administration of dbcAMP-Ca on growth performance and fatty acids metabolism in weaning piglets. A total of 14 early weaning piglets (7 +/- 1 d of age, 3.31 +/- 0.09 kg, Landrace x Large White x Duroc) were randomly divided into 2 groups: control group and dbcAMP-Ca group, and the piglets received 7 mL of 0.9% NaCl or 1.5 mg dbcAMP-Ca dissolved in 7 mL of 0.9% NaCl per day for 10 d, respectively. The results showed that the average daily gain (ADG) increased by 109.17% (P < 0.05) in the dbcAMP-Ca group compared with the control group. Besides, dbcAMP-Ca significantly decreased blood high density lipoprotein cholesterol (HDLC) concentration (P < 0.05) and significantly increased blood low density lipoprotein cholesterol (LDLC) concentration (P < 0.05) compared with the control group. Further, liver C18:2n6t content significantly increased in dbcAMP-Ca group (P < 0.05) compared with the control group. With the increase of C18: 2n6t content, the mRNA expression levels of peroxisome proliferator-activated receptor alpha (PPAR alpha) and hormone sensitive glycerol three lipase (HSL), of which genes are related to lipid metabolism, were also significantly increased (P < 0.05 or P < 0.01). All of the results indicated that dbcAMP-Ca improved the ADG, which was probably done by regulating fatty acids metabolism in the liver of weaning piglets.
