摘　　要：Background The present experiment aimed to evaluate the effects of commercially processed former foodstuffs(cFF)as dietary substitutes of corn,soybean meal and soybean oil on the growth performance,apparent total tract digestibil-ity(ATTD),hematobiochemical profiles,and liver gene abundance in broiler chickens.Two hundred one-day-old male ROSS-308 chicks were assigned to 4 dietary groups(5 replicates of ten birds per replicate)according to their average body weight(BW,38.0±0.11 g).All groups received a two-phase feeding program:starter,d 1–12 and grower,d 12–33.The control group(cFF0)was fed a standard commercial feed based on corn,soybean meal and soybean oil.The other three groups received diets in which the feed based on corn,soybean meal,and soybean oil was partially replaced with cFF at a substitution level of 6.25%(cFF6.25),12.5%(cFF12.5)or 25%(cFF25)for the following 33 d.Results The growth performance data showed no differences in BW or average daily gain among groups,although the average daily feed intake decreased during the grower period(12–33 d)and over entire experimental period(1–33 d)in a linear manner as the cFF inclusion level rose(P=0.026),positively affecting the gain to feed ratio(P=0.001).The ATTD of dry matter of the cFF-fed groups were greater with respect to control group and increased throughout the experimental period,whereas the ATTD of ether extract linearly decreased with increasing levels of cFF-fed groups compared with control group and throughout the experimental period(P<0.05).Additionally,a lin-ear increase in the heterophil to lymphocyte ratio,serum cholesterol,triglycerides and alanine-aminotransferase were observed with increasing dietary levels of cFF(P<0.05);however,no differences were observed in lipoprotein lipase or sterol regulatory element binding transcription factor gene abundance.Conclusions The results of this experiment demonstrate that it is possible to incorporate cFF into nutritionally balanced diets for broiler chickens,even up to 25%substitution level
