Abstract A total number of 130 frisian newly born calves were included in this study, age was ( 1 _ K Neoks) The animals were classified into the following groups :- Group I:included (60) clinically healthy frisian Calves. Group II: 5.rwluded nin teen f’risian calves shQrNing si~ns of acute bronchopneumonia. Group III: .i.ncluded thirty two f’risian calves of milo bronchopnetlmOn1a. Gr. up IV:-itlcluded ninteen frisian calves showing signs of pneumonia associated with enteritis. All Calves were SUbjected to carfull clinical eX3lI1ioa.tion dUring t he study, clinical findings were r’?7,istered. Prom each calf two blood samples were col Iected. Th~ ”irat one was I3l1 tic oagulf1.ted using Na heparin and was collected anaerobically. The snmples were preserved in ice-bath and measured within J hours. T he first samples were used for measurement of blood pH, carbon dioxide tension, oxygen tension, standard bicarbonate, total carbon dioxide and b~se excess using pH blood-gas analyzer UORNING MOdel-1G8. The sec ond blood samples was obt a.Lned w j thout anticoagulant for serum separation and were used for serum sodium (Na+ mmol./L.), potassium (K+ mmol./L.) ~~d chloride (Cl- mmol./L.) levels. Serum sodium and potassium levels were determined by using of flame photometer CORNING Model 400 (England Essex). Serum chloride was determined by using chloride meter CORNING Model 925 (England). Mean values of blood pH, Pco2. The aerum mean values of’Na +, K+ and Cl in group (I) and were 146.86 ± 4.9 mmol./L. 5.71 + O.4Jmmol./L. and 101.5 ± 4.019 mmol./L. respectively. The clinical finding of acute bronchopneumonia in newly born frisian ca”lV-eswere dyspnoic respiration, nasal discharge, coughing, severe fever and increase respiratory and pulse rates. Calves showing signs of acute bronchopneumonia and these were a highly significant difference (P 0.01)in values of blood pH (7.172 -+ 0.0)4), PC02 (61.67 ± 1.96) mmHg.) and base excess (-5.04 ± 3.)66 mmol./L.) and significant DROP (p 0.05) in P02 (30.436 ± 3.80 mmol./L.). In mild cases of bronchopnewnonia the signs were less severe and in the form of mild fever, slight increase in respiratory rate in addition the more or less spondee. The pH mean value was (7.248 ± 0.023), co 2 (54.84 ± 1.917 ma Dg.), P02 (27.20 ± 7.381 mmHg.) and B.E. (-).868 ± 1.888 romo1.fL.). In the third group (III) in which the calves showed signs of pneumoenteritis. The signs were dysphonic and respiratory distress are usually associated with signs of dehydration in which the hair was star, dry skin, sunken eye and Boiling of the area of anus with rascal matter. The most prominent findings was the significant DROP in pH (7.145 ± 0.072), blood HCO) (17.19 j; 2 .OJ mmo1. /L .), blood ToO2 (18.92 ± 2.6 OJ mmol. /L. ) and marked decrease in B.E. value (-11.90 ± 7.389 mmol./L.) respectively. Significant difference (P <0.05) was detected in serum potassium (5.978 + 0.23 mmol./L.) in fr1sian calves of acute bronchopneumonia. Highly significant decrease (P < 0.01) in values of serum sodium (128.505 ± 4.9 mmol./L.), serum chloride (92.42 -+ 4.16 mmol./L.) and increase in values of serum potassium (6.450 ± 0.215 mml./L.) in calves clinically w t h pneumonia t eri tis. There is no sign if 10 ant difference in values of electrolytes in Calves with bronchopneumonia (mild cases). |
