Effect of sex chromatin shape and axis on litter size and livability of newly born kids in shami and local does

Hamza Mizail AL-Khuzai and Wasan Jasim AL-Khazraji

Fifty does of Shami and Local goat breeds were selected from the flock reared at ruminants researches station in Agargof (25km west of Baghdad) through the year 2016 to investigate the effect of sex chromatin shape on livability of newly born kids and litter size. Results showed a significant effect (P≤ 0.01) of sex chromatin shape on litter size in Shami breed, the highest rate was found in does with drum stick shape while the least rate was in does with small club shape namely, 1.94 and 1.25 lamb/dam respectively. Livability affected significantly (P≤ 0.01) by sex chromatin shape in the Shami goat breed, the highest rate was in does with small club while the least rate was in does with drum stick shape namely, 0.87 and 0.53% respectively. Results showed a significant regression of litter size on sex chromatin axis in Shami breed. Positive and significant regression (P˂0.01) of litter size on vertical and horizontal axis of nuclei and number of nuclear lobs namely, 0.153% / um, 0.182 % / um and 0.001 % / lob respectively. Significant and positive regression (P˂0.05) of litter size on horizontal axis of sex chromatin (0.463% / um). Positive and significant regression (P˂ 0.01) of litter size on vertical and horizontal axis of nuclei and number of nuclear lobs namely, 0.090%/ um, 0.232 % / um and 0.189 % / lob respectively. Negative and significant regression (P˂0.05) livability on the vertical axis of nuclei and the number of nuclear lobs namely, 0.004% / um and - 0.0005% /lob respectively.
