Abstract

This study aimed to determine the physiological responses of PE does crossed with Boer bucks and their relationship with litter size and the sex of the kids. The method used was a farm experiment conducted on a goat farm owned by PT. Sedana Arif Nusa NTB. The study involved 48 pregnant does, of which 24, 14, 10, 7, and 9 carried single male, single female, twin male-male, twin female-female, and twin male-female kids, respectively. Pulse rate, respiration rate per minute, and rectal temperature were measured every two weeks, and pregnancy type was detected by ultrasonography. Differences between groups were tested using Student's t-test. The results showed that the birth weight of single male kids tended to be higher (3.18 ± 0.55 kg) than that of single female, male twins, female twins, and male-female twins. The respiratory rate during the last 50 days of pregnancy tended to increase from 14.0 breaths per minute at 100 days of pregnancy to 14.7 breaths per minute at 142 days. Pulse rate increased significantly from 27.7 beats per minute after 100 days to 37.1 and 37.2 beats per minute at 135 and 142 days of pregnancy, respectively. Chest circumference, abdominal circumference, and rectal temperature also increased with advancing pregnancy age. There were no significant differences in physiological responses—such as respiratory rate, pulse rate, and rectal temperature—due to different types of pregnancies during the last trimester. However, does with twin pregnancies tended to exhibit higher values for all measured parameters compared to those with single pregnancies.
