| Abstract | ||
| This study is conducted at the farm of the college of Agriculture_ University of Salahddin –Erbil from 6/6/2015 until 15/9/2015.In this experience, a total Number are used 16 local lambs in age 4-5 months and in weight 27.0+ 2.00 kg. The lambs are divided randomly into four lambs according to containment of maize bran in the dry materied of bush a follows, group (1) 0% maize bran, group (2) 25% maize bran, group (3) 50% maize bran, and group (4) 75% maize bran. At the end of the experience in 98 days, all lambs are slaughter in the same day to study the characteristics of the slaughter and the aim of study is to recognize the effect of maize bran instead of barley on the growth and performance of the lambs and the characteristics of slaughters. The results are There are no moral differences in the daily and total increase average of weight gaining of the Four treatments groups but there are mathematical differences between them as the third group got the best total and daily weight gaining and followed the second group, the fourth group less in weight. Although there were are no significant differences in the final weight, but the second group is the highest number (44.18) kg, followed by the third group (43.93) kg, then the fourth group (41.85) kg and the first group (40.00) kg. The design of the experience is being exchanging the rales 25 %, 50 and %,75% of barley by maize bran the second, third, and fourth group respectively. thus, the average of taking concentrated bush will be different. third group the highest average consumption is in the third group 1568.86gm/day followed by the 1st 1133.20 gm/day and the fourth group was in the end of 1016.39gm/day. The results of the replacement of maize bran at rates of 25%, 50 % and 75% conversion efficiency of food is as important as barley, which amounted to 8.03, 8.02, 6.38 kg dry matter / kg increase by weight, respectively, The results of carcass traits do not show absence of significant differences in warm and cold carcass and dressing percentage weight and fat kidneys and the thickness of the fat layer and fat automated analysis, but there are significant differences in the fat separated from the thigh where outperformed the first treatment, which amounted to 0.263 g, and the second transaction, which amounted to 0.145 g treatment fourth ,which amounted to 0.226 gm on the third treatment, which amounted to 0.296g .Counting results show significant differences in the vicinity of the thighs. While the results show a significant difference in the depth of the chest where it excelled fourth treatment, which amounted to 38.25 cm on the third treatment, which amounted to 36 cm and overtook third-treatment on the first treatment, which amounted to 34.75 cm. As well as the presence of significant differences between the four transactions in the chest circumference outperforming the second transaction, which in my language 78.25 cm on the third treatment, which amounted to 76.75 cm, and overtook the fourth treatment, which amounted to 76 cm on the first treatment, which amounted to 73.5 cm. | ||
