2 Abstract Effects of restricted feeding and re alimentation on intake growth cost and profit analysis development of non carcass components carcass physical and chemical composition fatty acid composition of whole carcass and longisimus dorsi muscle concentration of insulin like growth factor I IGF I were study by 48 and IGF I polymorphism were determine by 60 fat tailed weaned Lori Bakhtiari sheep The feeding management was divided to FRP and RAP During the FRP animals were randomly assigned to two groups of C and R groups The C animals were fed low quality roughage ad libitum and mixed concentrate the R animals were only fed low quality roughage In the RAP lambs in R group divided into two groups of R1 and R2 and received low quality roughage plus two different levels of concentrate supplement At the end of FRP and RAP six lambs of each group were slaughtered During restriction period the control group had a significantly higher P 0 05 ADG weight of liver and kidneys than restricted group The average weights of meat and bone in restricted group was higher P 0 01 but percentage of boneless DM and EE was higher P 0 01 in the C group Percent of unsaturated fatty acid of linolenic linoleic and total of polyunsaturated fatty acid and PUFA SFA ratio in total fat carcass was significantly higher P 0 01 in R group than C animals Percent of linolenic and linoeic acids of Longisimous dorsi muscle was higher in R group than C animals In the RAP and with both concentrate levels the compensating animals showed the same growth rate as the previous unrestricted ones and have better FC P 0 05 than control thus ADG and DMI gr kg BW 0 75 were similar between groups At the end of RAP net profit and net income for unit of product was lower in C group than R1 and R2 efficiency of R2 group were higher P 0 05 than control group The percentage means of bone in R2 was higher but subcutaneous fat was higher P 0 05 in C group than other groups Percentage of boneless CP and ash was lower P 0 01 in the C group than RRA groups In RAP palmetic acid and total of saturated fatty acid in R2 group was significantly lower than C group but there were no significant differences for any of fatty acid in Longisimous dorsi muscle PCR RFLP technique do not show polymorphisms for IGF I gene in Lori Bakhtiari sheep which observed the SnaBI enzyme used was not suitable for the study of IGF I polymorphism in this breed or perhaps other PCR procedure recommended In re alimentation period IGF I concentration was increased with growth in restricted and re alimentation animals and the concentration was higher than C animals Key words Feed restriction compensatory growth fattening performance carcass characteristic concentration and IGF I polymorphism Lori Bakhtiari lambs
