%X PF had no influence on intestinal morphology, weight, or DNA, RNA, or protein concentrations at 2, 4, and 6£¿wk of age. However, compared with SBO, PF significantly decreased FATP mRNA abundance at 4£¿wk (P£¿=£¿0.009) and 6£¿wk of age (P£¿<£¿0.001); decreased liver fatty acid-binding protein (L-FABP) mRNA abundance at 6£¿wk of age (P£¿=£¿0.039); and decreased C18:2 (P£¿=£¿0.015), C18:3 (P£¿<£¿0.001), C20:2 (P£¿=£¿0.018), ¦²-polyunsaturated fatty acids (¦²-PUFA) (P£¿=£¿0.020), and the proportion of PUFA (P£¿<£¿0.001) in the intestinal mucosa and decreased C18:2 (P£¿=£¿0.010), C18:3 (P£¿<£¿0.001), C20:2 (P£¿<£¿0.001), ¦²-PUFA (P£¿=£¿0.005), and the proportion of PUFA (P£¿<£¿0.001) in breast muscle at 6£¿wk of age.PF decreases FATP and L-FABP mRNA expression and decreased the proportion of PUFA in the intestinal mucosa and breast muscle.As an organ of nutrient absorption, the small intestine is very important for animals. The capacity to absorb nutrients depends mainly on the development of the intestinal mucosa. A previous study showed that morphological characteristics of the small intestinal mucosa are affected by diet [1]. Dietary lipids could affect intestinal morphology [2-4], influencing the fatty acid (FA) composition of the apical enterocyte membrane [5] and the fluidity of brush border membranes [6]. This in turn could alter the transportation and diffusion of certain nutrients across the intestine [7].Poultry fat (PF), an available ingredient source, has been widely used as an energy source in swine feeds. A previous study showed that PF appeared to be more efficiently utilized than swine fat for both body weight (BW) gain and the production of carcass energy [8] and did not influence swine performance compared with soybean oil (SBO) [9]. However, few data exist on the effect of PF on the development of intestinal structure and on the absorption and utilization of FA compared with other animal fats or plant oil.Recently, there has been an increasing interest in improving the quality of meat.
