CHANGES IN UTERINE CAPABILITY DUE TO INCREASED LITTER SIZE AT 7 WEEKS OF PREGNANCY IN KACANG GOAT
Get PDFThe purpose of this research was to study the changes in uterine support capability power due to increase of litter size in Kacang goat. In this study, 9 pregnant female Kacang goats were divided into 4 different groups based on litter size, namely 1, 2, 3, and 4. At 7 weeks of pregnancy, the experimental Kacang goats were sacrificed to observe the macro and micro parameters of the uterus. The results showed that the litter size had a quadratic relationship with micro parameters of uterus but it had a linear relationship with macro parameters of the uterus. The variables of uterine glands area, glands lumen area, and cytoplasmic area reached maximum condition at the litter size of 2.5. Litter size had a linear relationship with the volume, weight, and dimension of the uterus. It can be concluded that the optimal number of litter size in Kacang goat was two offsprings which was proven by the optimal function of the uterus to support fetal development

Get PDFThis study aimed to determine the pregnancy percentage of Ongole (PO) breed cattle by estrus synchronization and ovulation synchronization. This study used 22 cattle that were divided into three groups: Estrus synchronized cattle (K1, n= 5); ovulation synchronized heifers using ovsynch (K2, n= 6); and ovulation synchronized cow using ovsynch (K3, n= 11). Parameters measured were diameter of corpus luteum (CL) in estrus synchronization, follicular diameter upon synchronization and artificial insemination (AI), and percentage of pregnant cattle. Data obtained were statistically analyzed using analysis of variance followed by Duncan test. Results showed no significant differences (P0.05) of CL diameter at the time of estrus synchronization in all groups of cattle with an average of 16.633.79 mm. The CL diameter at the time of estrus synchronization was not significantly different among groups, with an average of 8.80 2.07 mm. Diameter of follicles during ovulation synchronization was also not significantly different among groups. The average diameter of follicles was 9.012.05 mm. Diameter of follicles at the time of estrus and ovulation synchronization was not significantly different among groups with an average diameter of follicles of 10.942.10 mm. The pregnancy percentage of K1, K2, and K3 were 60%, 16%, and 36%, respectively. There was no correlation between the diameters of follicles during estrus with the pregnancy percentage. Estrus synchronization produced higher pregnancy rate than ovulation synchronization in cow or heifers
