There is evidence to suggest that poultry may have a dietary requirement for metabolically available chromium(Cr)that exceeds the amount provided through wheat soybean meal *** objective of the present study was to investigate the effects of dietary supplemental organic Cr from Cr propionate at different dose levels(control=0μg/kg,T1=200μg/kg,T2=400μg/kg)on the growth performance,carcass traits,and meat quality of *** gain and feed intake of each treatment were recorded at the start and after 14,28 and 35 d,and feed conversion ratios(FCR)were calculated ***35 d of age,birds were randomly selected and euthanized for carcass *** of the first trial indicate that both Cr propionate treatments increased final body weight(Ppropionate supplementation improved(Ppropionate supplemented groups(T1&T2).Furthermore,the Cr propionate supplemented T2 group displayed a significantly lower FCR than the control and T1 group(P=0.027).Finally,Cr propionate supplementation increased the dressing percentage compared to control birds(Ppropionate supplementation(T1&T2)increased final body weight and decreased FCR compared with the control *** effects were highly significant(Ppropionate supplementation also increased(P<0.0001)carcass yield,dressing percentage,breast meat yield,leg and thigh weights compared with the control *** conclusion,growth performance,feed conversion,carcass yield,breast and leg meats of broiler birds can be significantly improved by dietary inclusion of Cr *** pro

The object of this study was to investigate the effects of chromium propionate replacing 25%rumen-protected choline(RPC)on production performance and blood indicators of perinatal dairy *** to the principle of ensuring that chromium propionate and RPC were fed 14 days prepartum,27 healthy Holstein cows(age,parity,lactation volume,body condition and expectancy were similar)were randomly divided into three groups(GroupsⅠ,ⅡandⅢ),with nine cows in each *** in GroupⅠwere fed basal diets;cows in GroupⅡwere fed the same basal diets with 10 g•d-1 RPC per cow;and cows in GroupⅢwere fed the same basal diets,but 7.5 g RPC and 2.5 g chromium propionate(4 mg chromium)per *** results showed that dry matter intake(DMI)of prepartum in GroupsⅡandⅢwas significantly increased(P0.05).The milk fat content in GroupⅢwas significantly higher than that in GroupⅠon the 7th day of postpartum(P0.05).The somatic cell counts in GroupⅢwere significantly lower than those in GroupsⅠandⅡon the 14th and 21st days of postpartum(Pchromium propionate reduced production costs and improved dairy farming benefits.
