ABSTRACT Aiming to complete evaluation of feeding on reed forage this study concerned with measuring changes in carcass characteristics and blood profile due to feeding reed either fresh RF silage RS or hay RH to Rahmani growing lambs. Changes in most tested blood parameters were not significantly affected by type of feeds tested. But hemoglobin Hb mean cell hemoglobin concentration MCHC and lymphocytes were significantly more with RS than RH. The same trend was noticed for total protein and globulin. The other blood parameters tested did not show preference for any of the tested diets. Carcass cuts show significant P 0.05 increase in shoulder and legs weight of groups fed RS or RF compared to RH and Berseem hay BH. The prime cuts in general was heavier with RS followed by RF then estimates with RH and BH were significantly less. Weight of 9-11 th ribs cut was increased with RS 530g and RF 524g than BH 479g and RH 462g. Thus meat weight was significantly higher with both of RS and RF compared with BH and RH. The same trend was observed with fat weight. The animals fed RH ration had the lowest eye muscle area while the largest area was recorded with RS where difference was significant between RH and RS only. Accordingly reed in general has slight better but sure not less feeding values reflected on carcass and blood parameters when fed as silage compared to BH and other types of reed tested. INTRODUCTION The shortage of animal feeds in Egypt especially in the draught summer season is considered one of the main problems in animal production. Most animal feeding in this period depends on concentrate feed mixture which has high cost and some agricultural residues. Green forage or silage represent a cheap food for ruminants either for meat or milk production Soliman et al. 1997 and Ahmed et al. 2009a. Some studies Gabr et al. 1999 and Shehata et al. 2006 indicated that reed forage or silage had a good palatability and adequate feeding value for dairy Zaraibi goats and could nutritionally and economically replace high quality summer forage like sorghum or maize silage resulting in reducing the feed cost. In a recent studies Ahmed et al. 2009b and 2011 concluded that reed forage silage recorded the highest digestibility feeding value and growth performance with Rahmani lambs and the highest milk production with good economic return with lactating Zaraibi goat without any adverse effect on milk quality. Literature on the effect of using reed forage either fresh silage or hay in lambs rations on carcass quality is scarce. Therefore the main objective of the present work was to recognize the effect of substitution of berseem hay with reed forage in different forms fresh silage or hay on carcass quality and blood profile of Rahmani lambs.

Different offal and organs were weighed as well as carcass cuts. Hot carcass depended on lift side of the carcass was weighed. The 9-11 th ribs longissimus dorsi were chilled then separated to lean bone and fat to estimate the physical and chemical composition beside measuring weight area and thickness of fat. Samples of feed and meat were analyzed according to A.O.A.C. procedures 1995 Data were statistically analyzed using SAS 2003. The significant differences between means were assigned according to Duncan 1955. RESULTS AND CONCLUSION 1-Blood profile 1-1-Hematological parameters: Concerning hematological parameters the results indicated that most tested blood parameters were not significantly affected by the tested types of experimental rations Table2. However as a trend RS caused higher hemoglobin 12.07 MCHC 36.07 and lymphocytes 64.33 compared to other tested feeds. Similar results were observed by Shehata et al. 2006 with goats fed reed as silage or hay compared with berseem hay. These results may indicate the beneficial effect of feeding RS on lambs metabolism. Similar results were observed by Shehata et al. 2006 and Ahmed et al. 2009b. They reported that both of Hb and RBCs were higher with RS compared with the other such as RH and this may be attributed to the higher Fe and Cu in the reed which may be

INFLUENCE OF USING REED FORAGE ON BLOOD PROFILE AND CARCASS QUALITY OF GROWING RAHMANI SHEEP …………… Ahmed M. E. et al. 2011 28 more available for lambs in either silage or fresh forms than hay. 1-2- Biochemical parameters: Table 3 shows that most biochemical parameters were not significantly different among the treatments. Whereas RH had significantly lower TP and globulin than other tested rations. In general RS had the highest concentrations of most parameters followed by RF then BH. . Similar results were observed by Gabr et al. 1999 with goats fed reed forage and/or sorghum plants and Shehata et al. 2006 when used reed forage silage or hay or berseem hay with dairy goats. Minerals concentrations were in general not differed significantly among the tested rations. P was significantly higher with RS and RF than other two rations. Shehata et al. 2006 observed that serum phosphorus inorganic was higher with silage reed or maize compared with hay reed or berseem. Kaneko 1989 cited that the normal physiological range of blood phosphorus inorganic is from 5.0 to 7.3 mg/dl. The enzymes activity AST ALT and ALP showed some fluctuation among groups but without significance. The same trend was observed by Shehata et al. 2003 and 2006. Generally the results indicated that measured blood parameters showed slight differences among tested diets where all values were within the normal physiological ranges reported by Jain 1986 and Kaneko 1989 for healthy goats. This indicate that to a reasonable level reed forage in different forms have no hazardous or anti-nutritional effect when fed to animal. 2- Carcass characteristics: 2-1- Dressing percentage: The data of hot carcass weight and dressing percentage of growing Rahmani lambs fed tested rations containing different reed forms fresh silage or hay and berseem hay are presented in Table 4. The results show that feeding RS had significant better performance than RH and BH in fasting and empty BW. which was reflected also on significant improvement in dressing values and hot carcass weights. RF came next to RS and had better performance than BH but differences were insignificant between RH and BH either for fasting or empty BW or hot carcass and dressing values. RH was the least in all carcass parameters however the decreases than BH were not significant. The same trend was observed with prime cuts as shown in Table 4. The highest prime cuts was observed with RS 16.0 kg or 65.80 followed by RF 15.0 kg or 64.58 then BH 13.8 kg or 64.09 and finally RH 13.25 kg or 63.52. The improvement in carcass characteristics with using reed silage in lambs rations is compatible with the changes in body weight and growth rate in response to present feed sources Ahmed et al. 2009b. The obtained values in the present study were approximately similar with those obtained by Abdelhamid et al. 2004 with growing Rahmani sheep. Similarly the values dressing percentage relative to fasting weight A were ranged from 50.2 to 52.7 whereas dressing relative to empty weight B were ranged from 56.4 to 59.5 in slaughtered Rahmani sheep Abou Ammou and El-Hosseiny 1999. Stomach fat ranged from 0.27 to 0.33 kg and total internal fat from 1.97 to 2.53 where RS had the least estimates while the highest values were not specific to one of the other treatments especially when significance considered. 2-2- Carcass cuts: The data of carcass cuts leg loin neck rack brisket flank and tail are presented in Table 5. It is interest that major cuts shoulder and legs showed significant increase with RS or RF than RH or BH. RS had the heaviest cut weights followed by RF without significance in difference. RH had the least cuts weights followed by BH without significance differences between them. All other cuts did not show significance differences though RS had in general the heaviest cut weights while RH the least weights.. The same trend was observed with Gabr et al. 2003 and Abdelhamed et al. 2004 with most carcass cuts as of hot carcass weight.

As fasting weight significantly differed among tested diets the offals and organs weights as percentage of fasting weights was consider for comparisons. The obtained percentages Table 7 revealed that all offals heart kidney lungs and spleen and organs head pelt and legs were not significantly differed due to experimental rations. The same effect was observed also with full and empty digestive tract. The values of different offals and organs in the present study were nearly similar to those obtained by Gabr et al. 2003 with growing Rahmani lambs who found that values of total offals as of fasting weight ranged from 3.73 to 4.04 . In this respect Ahmed 2003 observed that most weights or from fasting weight of offals and organs were not significantly affected with increasing berseem hay in the growing kids ration. 2-4- Carcass quality and chemical analysis: Data of carcass quality and chemical analysis of the longismus dorsi are shown in Table 8. The RH group had the lowest weight of the 9-11 th ribs cut while the highest was recorded in the group received reed silage RS. The differences in weight of 9-11 th ribs cut between either treatments BH and RH on one side and RS on the other side were significant. Also there were significant differences in meat fat and bone weights and L.D. area as shown in Table 8. Similarly the highest values of meat : fat and meat : bone ratios were recorded with RS 2.19 and 2.48 respectively then RF 2.18 and 2.42 respectively followed by BH 2.11 and 2.40 respectively while RH group recorded the lowest values 2.08 and 2.39 respectively. Values of meat to fat and meat to bone in the present study were noticeably lower than those reported by Ahmed 2003 and Allam et al. 2007 for Zaribi kids and Farafra lambs respectively while it recorded approximately similar values with Rahmani lambs Abdelhamid et al. 2004. They found that values of meat : fat ratio ranged from 2.20 to 2.28 vs. 2.52 to 2.62 for meat : bone. Chemical composition of L.D. show that the highest and lowest percentage of CP and EE respectively were in RS and the differences in CP were significant. The values of chemical composition in the present study were approximately similar with Gabr et al. 2003 and Abdelhamid et al. 2004. CONCLUSION It could be concluded that feeding reed as silage could improve dressing percentage carcass weight and most meat quality parameters compare to feeding reed either fresh or as hay. Meanwhile RS is compatible to Berseem hay in most carcass characteristics and blood profile. So economic wise RS is a good summer alternative to Berseem hay. REFERENCES A. O. A. C. 1995.
