In this study 400 cow's lymph nodes from different areas of body such as : Mandibular, parotid, lateral retropharyngeal, prescapular or superficial cervical, iliac, prefemoral or subiliac, and popliteal lymph nodes from Shahrekord abattoir were collected. The specimens were selected from inbreeding breed and two sexes with aged 1 to 4 years .After collecting of specimens factors such as : Length,width and thickness of each lymph node were measured by calliper device. All factors between two sexes and different ages were analysed and compared using t and Duncan's tests (p0.05) . It was revealed that , the maximum length, wide and thickness were observed in prescapular (72.98 ±1.37 mm), iliac (34.61± 9.94 mm) and prescapular(16.18 ± 4.11mm) lymph nodes respectively and on the other hand, the minimum length,width and thickness of lymph nodes were observed in mandibular (40.18 ± 8.01mm),(22.37 ± 5.44mm) and iliac (11.06 ± 1.94mm) lymph nodes respectively. These factors were larger in male than in female. By comparing factors between ages , the maximum dimensions of lymph nodes were observed in 2 year old animals.
