Eighty five Hamdani (H) and 41 Karadi (K) ewes were included in four body condition score (BCS) groups, to study the effect of ewe BCS at tapping on their fertility, lambing percentage, milk production, lamb weights, carcase weight and meat production and their financial returns. Ewes were fed 400g /day/head of concentrate ration which increased to 1 kg/day/head during lactating season. Lambs were on concentrate free feeding from weaning to slaughter. Ewes in BCS3 were found to have significant (p< 0.05) superiority than those in BCS1 and 4 in fertility percentage and than both breed ewes in BCS1 and K ewes in BCS4 in lambing percentage . The significant (p< 0.05) high milk production of the two breed ewes in BCS3 hence for significant (p< 0.05) heavier lamb weaning weight and ADG for H and K breed when compared to those in BCS1 and BCS2 .BCS3 group drew a head of others in weaning percentage and lamb weaning weight to original ewe number ratio for H and K breed. While the lower recoreds were observed for both breed lambs in BCS1 . H and K lambs in BCS3 last 145 and 162.5 days to slaughter which were significantly (p<0.05) shorter than those 200.7 , zero days of both breeds in BCS1 respectively. Carcase weight of H and K lambs in BCS3 and BCS1 were 13.8, 13.3 kg and 11.8, zero kg respectively. While carcase weight to original H and K ewe number ratio in BCS3 and BCS1 was found to be 12.4, 11.8 and 5.1, 0.0 respectively. So the financial returns of the BCS1,2,3 and 4 could be summarize 61200, 93600 ,148800 and 109200 ID for the H breed and 0.0, 106800, 141600 and 72000 ID for K breed respectively. INTRODUCTION The body weight can give an idia about the ewe condition, but with a different body sizes the weight will be changed at a same body condition score (BCS). It is very difficult and may be expensive to weigh a large number of animals in a big herd, so the BCS can be used as a guide at breeding season or to predict the amount of meat can be dressed before slaughtering and marketing the animals. Hand assessment is an easy and useful measurement used by the butcherman to buy lambs for slaughtering, and by the farmer to manage the ewes at the mating season. Six degrees for the BCS were mentioned in Australia by Jeffries (1961) and Russel et al (1969). The British MLC (1981) gave 5 degree desecrption for BCS. Sheep BCS was found to be highly correlated to their reproductivety (Gunn et al 1991) . Gunn et al (1969) found a significant effect of body condition of the ewe on the number of lambs born, and lambing percentage increased 6-10 % when BCS improved one degree (Pattison 2002). Improving the BCS by flushing before breeding season is necessary (Kazzal and AL-Saigh 1980), because it activates the most important reproductive characters such as fertility, liveability and prolificacy (Dahal,1987). The idia of this study was planed to study the effect of the BCS on the productivity of the local Hamdani (H) and Karadi (K) ewes. Mesopotamia J. of Agric. (ISSN 1815-316X) Vol.( 39 ) No. ( 3 ) 2011 2 * Part of Msc. Thesis Received 3/5/2010 accepted 4/10/2010 MATERIALS AND METHODS Eighty five ewes (44 Hamdani (H) and 41 karadi (K)) were assigned at the agriculture farm and graded by handl assessment using MLC (1981) scor (1= very thin and 5= over fat), which described by pattison (2002) . All the ewes were weighed and singed in four grading groups (Table 1). All the ewes were given 400 g / ewe / day concentrate ration 55% barley seeds, 35% wheat bran, 8% cotton seed meal and 2% salt, limestone and vitamins) during mating and pregnancy period, then increased to 1 kg/ewe/day after lambing with a usuall daily grazing. Free concentrate feeding was allowed for the lambs from weaning to slaughter. Fastening ewe body weight and condition score were recorded at the beginning of the experiment and regular every 15 days intervals. All the lambs were weighed within 24 hours after birth and then every 15 days until all the lambs were slaughtered . Milk production measurements commenced in the 2nd week after lambing and regular weekly for 20weeks. All the lambs were killed at average live body weight of 31 kg. Cold Carcase weight and rib eye area were taken and the planemeter was used to determine the rib eye area . Dressing percentage and financial returns of each BCS group were calculated. All the data collected were analyzed by using the SAS system (Anonymous , 2001) . Duncan's multiple range test (1955) method at 5% level was used for significant differences calculations between means of the treatments if the analysis of variance indicated significant differences. The following mathematical model was fitted for all traits. Yijk = μ + Si + Bj + eijk , when μ = the over all mean Si = the ith body condition scores Bj = the jth breed eijk = the random error effect. Table (1): Number of H and K ewes in each BCS group.
