Abstract
The research was conducted at AL-Fayhaa station in north Babylon provence with has group of awassi lambs from 15-12-2011 to 30-6-2012 to study effect of ration change during three periods (first period concentrated% ration +25kg of soft wheat straw for 100kgconcentrated ration)(second period concentrated % +25kg forage for 100kg concentrated ration)and(third period concentrated% +25kg section wheat straw for100kg concentrated .The result appeared that the average increasing weight was 11.250, 10.480 and 9.850kg whith amount of increasing weight of 187.65 , 171.80 and 161.14 gmlamb respectively , the period of fattening was significant (p<0.050) of the two types. There was significant effect (p<0.05)at the amount of concentrated ration cons- ed which for each lambs and also at the amount of roughage consumed which increasing during the second and third period compared with the first period .The total ration consume (concentrated + roughage )by the lambs for the three period 1031.40 , 1485.50 and1850.50 gm respectively , the amount differed significantly (p<0.05)according to fattening period which were 5.50, 8.64 and 11.48 kg ration kg weight that means feed conversion efficiency was excellent during the first period ,where as significant difference in total increasing weight during January and February (first period)5.68 and 5.67 kg respectively ,where as the second period (March and April) 5.07 and 5.32 kg respectively ,the period (May and June) 5.62 and 4.23 kg respectively. We conclude from this research had changing the ration according the style used the research had an imprvelant effect in growth speectally during increasing weight and feed conversion efficiency .
