Studies on the Clinical Pathological Values offourteen-breed ChickensMin-Siu ChenAbstractThe purposes of this study was to establish the normal haematolgical and blood chemistry values of fourteen-breed chickens and to compare the differences between breeds and sexes. Twenty-six blood chemistry values, thirteen haematological values were estimated for fourteen-breed chickens. A total of 597 chickens were sampled from 14 flocks. Haematological values varied with sexes and breeds of chicken. The highest average number of erythrocytes (M/uL) for male chicken was found in TW breeds (4.26±0.28) and the lowest number was in AC breeds (3.18±0.37). In the female, the highest average number of erythrocytes (M/uL) was in B breeds (4.15±1.11) and the lowest number was in F breeds (2.69±0.37). The highest average concentration of hemoglobin (g/dL) for male chicken was found in CW breeds (17.65±2.38) and the lowest concentration was in AC breeds (12.05±1.38). In the female, the highest average concentration of hemoglobin (g/dL)was in B breeds (15.09±3.99) and the lowest was in F breeds (10.64±1.34). The highest average value of hematocrit (%) for male chicken was found in TW breeds (47.93±3.34) and the lowest value was in AC breeds (35.86±4.89). In the female, the highest average value of hematocrit (%) was in B breeds (41.37±12.29) and the lowest value was in KT breeds (29.53±4.28). A higher concentration of hemoglobin, red blood cell and hematocrit (packed cell volume) were found in the male chicken. The results of male and female chicken blood chemistry values ware as following: The highest average concentration of total protein (g/dL) for male chicken was found in NG breeds (5.10±1.06) and the lowest concentration was in J breeds (3.74±0.36). In the female, the highest average concentration of total protein (g/ dL) was in S breeds (6.24±1.16) and the lowest concentration was in AC breeds (4.39±0.56). The highest average concentration of albumin (g/dL) for male chicken was found in F breeds (1.96±0.77) and the lowest concentration was in T breeds (1.41±0.22). In the female, the highest average concentration of albumin (g/dL) was in S breeds (2.33±0.51) and the lowest concentration was in AC breeds (1.57±0.19). The highest average concentration of calcium (mg/dL) for male chicken was found in NG breeds (14.25±1.33) and the lowest concentration was in CW breeds (10.06±2.37). In the female, the highest average concentration of calcium (g/dL) was in F breeds (16.00±2.48) and the lowest concentration was in CN breeds (11.61±1.50). The highest average concentration of phosphorus (mg/dL) for male chicken was found in AC breeds( 10.37±1.02) and the lowest was in NG breeds (5.66±1.56). In the female, the highest average concentration of phosphorus (mg/dL) was in AC breeds (10.58±0.98) and the lowest concentration was in L2 breeds (7.02±1.25). The highest average concentration of cholesterol (mg/dL) for male chicken was found in AC breeds (173.73±44.34) and the lowest concentration was in TW breeds (103.21±10.12). In the female, the highest average concentration of cholesterol (g/dL) was in T breeds (219.50±52.20) and the lowest concentration was in CN breeds (144.75±31.04). The highest average concentration of triglyceride (mg/dL) for male chicken was found in F breeds (228.55±379.01). and the lowest concentration was in D breeds (62.57±25.76). In the female, the highest average concentration of triglyceride (g/dL) was in KT breeds (1359.56±519.26) and the lowest concentration was in AC breeds (73.14±17.88). The highest average concentration of iron (μg/dL) for male chicken was found in F breeds (222.71±289.14) and the lowest concentration was in B breeds (96.29±32.86). In the female, the highest average concentration of iron (μg/dL) was in T breeds (641.52±24961) and the lowest concentration was in AC breeds (125.82±23.26). Differences were observed between chicken sexes in total protein, albumin, calcium, phosphorus, cholesterol, triglyceride, iron. The highest average concentration of sodium (mmol/L) for male chicken was found in AC breeds (178.50±3.71) and the lowest concentration was in J breeds(156.50±2.44) In the female, the highest average concentration of sodium (mmol/L) was in AC breeds (176.86±3.96) and the lowest concentration was in LM breeds (153.76±4.97). The highest average concentration of potassium (mmol/L) for male chicken was found in AC breeds (5.96±0.93) and the lowest concentration was in CW breeds (3.24±0.68). In the female, the highest average concentration of potassium (mmol/L) was in AC breeds (6.23±0.68) and the lowest concentration was in LM breeds (3.66±0.56). The highest average concentration of choloride (mmol/L) for male chicken was found in AC breeds (134.55±4.76) and the lowest concentration was in CW breeds (114.05±1.70). In the female, the highest average concentration of choloride (mmol/L) was in AC breeds (133.05±2.79) and the lowest concentration was in LM breeds (107.24±6.91). The rsults were showed that the concentrations of serum sodium, potassium and choloride of broilers increased significantly.
