Abstract:
This experiment was conducted to estimate the age of the fetus by measuring the dimensions of the body of Nubian goat does after receiving 100% pure males. The study included (17) does Nubian goats in the Selait farms in the Shrg Alneel locality with 2_2.5 years old age. Number of birth was 26 (8 single, 9 twins) the age of the fetus was divided into two categories: less than 110 days and more than110 days. Pelvis width was measured for the pregnant does, it was 44.5cm for does gave single birth and 46.20 cm for does gave twin birth. Pelvis length for right side was44.12cm, 45.85cm and 43.71cm, 44.11cm for the left side , and the abdominal length was 21.02cm, 20.91cm and gestation length was 147.38 day, 145.89 day for single and twins respectively. The body measurements in the length of the pelvis on the right side had a significant effect on the measurements of the other body in the individual abdomen size. The fetus was divided into groups as follows:
Pelvis width was (44.26), (46.5) cm and pelvic length for left side (43.19), (44.75) cm and right pelvis length was 45.04, 45.05cm and abdominal length was 21.37, 20.50cm for <110 and >110 day respectively. Pelvis width had a significant effect on the other measurements in both groups (<110, 110>) day for fetal age.
