The present study was conducted on native Iraqi buffalo raised in Nineveh governorate in four different regions from the governorate by using data belongs to 120 buffaloes (118 milking buffalo and 2 buffalo bulls ) by visiting to 6 buffalo breeder which performed randomly ( 20 animals per breeder ) from the period of 11/7/2010 to 16/7/2010 for the purpose to knowledge and fixation morphology characters for milking buffalo and to correlation coefficients between these treats and they found these results : 1.

Over all mean ± SE for front teats length, hind teats length, the diameter for front and hind teats were : 6.95 ± 0.11 , 7.55 ± 0.13 , 3.28 ± 0.08 and 3.63 ± 0.18 cm respectively .

2.

Over all mean ± SE for distance between front teats , distance between hind teats , distance between front and hind teats and circumference for udder were respectively : 16.45 ± 0.30 , 9.47 ± 0.21 , 10.29 ± 0.17 and 45.62 ± 0.72 cm .

3.

Effected of parity has a higher significant on length of front teats and their diameter only , and length of teats was increased from 6.74 cm in first group to 8.50 cm in fourth group , and the same things was happen for teats diameter ( 3.10 and 3.92 cm ) respectively .

4.

The location for taking measurements was high significant effect for distance between hind teats and significant (p<0.05) for udder circumference and all studied treats were exceeded in 4th location ( Badosh region ) for all other position .

5.

They found a highly positive significance correlation between length of front teats with length of hind teats (0.05) and with diameter of front teats (0.42) .

Also , they found a positive and significance (p<0.01) between udder circumference with distance between front teats and distance between hind teats and distance between front and hind teats were (0.62, 0.59 and 0.48)respectively.Thus, further studies on this animal require a joint effort between breeders and the research community to give a comprehensive assessment of this animal is important economically.
