Popis: We investigated the effect of different fat sources on growth performance and intestinal health in weaned piglets. A total of 72 21-day-old weaned piglets were divided into 3 groups the CON group with 2.5% soybean oil, TRE1 with 2.5% emulsified balanced oil powder and TRE2 with 2.5% emulsified coconut oil powder. These two experimental oil powders were emulsified with the emulsifier (lysophospholipid). The average daily feed intake in TRE1 was significantly higher than that in CON (P < 0.05). The apparent total tract digestibility (ATTD) of ash in TRE1 was significantly higher than that in CON (P < 0.05). Compared with CON, TRE1 tended to improve ATTD of dry matter (P = 0.075), serum triglyceride (P = 0.062) and serum-free fatty acids (P = 0.090). The jejunal villus width of piglets in TRE1 and TRE2 was significantly increased (P < 0.05) and the duodenal crypt depth was significantly decreased (P < 0.05). Compared with CON, TRE1 significantly increased the mRNA expression levels of jejunal Occludin, Claudin-1 and ZO-1 (P < 0.05). From the results of the present study, we concluded that dietary supplementation of 2.5% emulsified balanced oil powder has more obvious effects on enhancing the growth performance of weaned piglets by improving lipid metabolism, intestinal tissue development and barrier function.
