TY - JOUR ID - TI - EFFECT OF DIFFERENT LEVELS OF TREATED ROUGHAGE AND UN-DEGRADED CONCENTRATE ON RUMEN PARAMETERS OF ARABI EWES AU - Jalal Okaily Yeasar , Murtda F.Al-Hello , Jaffer M. Jassim PY - 2015 VL - 14 IS - 1 SP - 219 EP - 227 JO - Basrah Journal of Veterinary Research مجلة البصرة للابحاث البيطرية SN - 18138497 24108456 AB - The present study was conducted at the Animal Farm/ College of Agriculture/University of Basrah during the period from 2/12/2012 to 2/3/2013. The studyincluded 24 milking ewes aged around 2-4 years, having single lamb, closely lambingdate and weighted 42 kg. After giving the ewes preliminary period of 10 days, theywere distributed randomly and equally to six feeding groups. The first group was fed60% concentrate and 40% roughages; soya bean meal was treated by formaldehyde.The second group was fed 60% concentrate and 40% roughages with untreated soyabean meal. The third group was fed 50% concentrate and 50% roughages with treatedsoya bean meal. The fourth group was fed 50% concentrate and 50% roughages withuntreated soya bean meal. The fifth group was fed 40% concentrate and 60%roughages with treated soya bean meal. The sixth group was fed 40% concentrate and60% roughages with untreated soya bean meal (control). The ration was given as 4%of live body weight. The concentrate consisted of 40% barley, 20% corn, 30% wheatbran, 7% soya bean meal, 1% salt and 2% Calcium bicarbonate. Roughage was wheatstraw treated with 4% urea and 3kg/ton yeast. Treated soya bean meal reduceddegradable protein from 70% to 60%. There were no significant differences amongfeeding groups in pH, total bacteria and cellolytic bacteria before feeding. However,the differences reached significant level (P<0.05) after 3 hours of feeding. The thirdgroup recorded highest pH value (6.82) and cellolytic bacteria (8.7x 106). The fifthand sixth groups showed highe significant improvement in total number of bacteriawhen compared with other groups (11.37x107 and 11.86x107).Propionic acid leveland the percentage of acetic: propionic were significantly (P<0.05) influenced bydifferent treatments, comperation with fivth and sixth treatment.
