Real time B-mode ultrasound scanner becomes very effective tools to detect early pregnancy diagnosis in small ruminant such as goat. Ultrasound scanner used in two way which are transrectal and transabdominal probes. Transabdominal probe used as it is less harmful than transrectal probe. The objectives of the study are: 1) to detect the ultrastructural images in non-pregnant does for artificial insemination purposes using ultrasound scanner, 2) to diagnose of difference foetal ultrastructural images obtained during gestation period using ultrasound scanner and 3) to compare the foetal ultrastructural image obtained from trans-rectal and trans-abdominal probes of ultrasound scanner. There are three pregnant does and 26 non-pregnant does with two successfully delivered out of 29 totals does chosen in this experiment. The ultrastructural images visible are ‘C’ shape placentome, heartbeat, foetus and hydrometra. It is shown that the size of heart determines the age of foetus during gestation period. At the end of this study, the farmers should be exposed to this modern way to diagnose the pregnancy and non-pregnancy in does and another ruminant. The farmer is able to manage their farm management for pregnant does and ready the non-pregnant does with culling or rebreeding for second time. The result of the study would be an alternative reference to increase the production of milk and farm management in goat industry at UDGF and Malaysia especially. The ultrasound technique to diagnose pregnancy in goats.

The purpose of this paper was to improve the reproductive performances of sows after weaning in a private swine farm. The main objective was to implement modern reproductive biotechnologies (estrus synchronization, artificial insemination and early pregnancy diagnosis) in order to increase the economic efficiency of the reproductive sector of this farm. The biologic material used for the research was represented by 300 sows whose estrus was synchronized using three hormonal procedures (Regu-Mate administered collectively, Regu-Mate administered individually and PG600) as well as naturally, using stimulating boars. The results showed that the best methods of estrus induction and synchronization in sows use either Regu-Mate administered individually in fodder or PG600.

Ultrasound Scanner

Serial transabdominal ultrasonographic scanning was performed to measure femur and humerus length of foetuses of Saanen goats to establish their gestational stage. Data were obtained from 38 goats that became pregnant after artificial insemination. Animals were restrained in a supine position on a special table designed for this purpose. Humerus and femur length were measured at weekly intervals starting from week 8 of gestation till the end of gestation. Real-time ultrasound scanner equipped with switchable frequency (5-7.5 MHz) micro convex probe was used in the present study. Humerus and femur length showed strong positive correlation with gestational age (r2 = 0.95). Measurements of humerus and femur of foetuses are useful indicators to predict gestational age at the 2nd and 3rd trimesters in Saanen goats. Measuring of only one bone length is quite enough. Incorporating of both measurements within a multiple regression equation did not improve predictive capacity of the bones. The results of the study were used to construct reference charts and gestational equations in Saanen goats utilizing humerus and femur measurements. In Sudan, this is the first study utilizing measurements of the femur and humerus and the first study comparing the length of the humerus and femur for predicting gestational age in Saanen goats.

Abstract Saliva sampling is a non-invasive, simple and low-cost procedure. The aim of this study was to confirm the presence and changes of saliva crystallization in domestic cattle during synchronized oestrous cycle and early pregnancy. We verified saliva crystallization as a method for early pregnancy diagnosis. Eight Holstein cows were included into the research. The samples were collected daily from 16th day before to 34th day after artificial insemination (in total 51 days). We observed the following types of crystallization: none, dotted, branch-like, fir-like, fern-like and combinations of them and an atypical pattern. We confirmed the presence of saliva crystallization in cattle and its changes during oestrus synchronization process, insemination and post-insemination periods. We found significant differences in pregnant and non-pregnant animals between 20th and 29th day after insemination. We concluded that pregnancy diagnosis by saliva crystallization might be possible but the practical application of this method is currently unfeasible.

The studies aimed to evaluate the pregnancy rate (PR) for timed artificial insemination (TAI) after G7G-Ovsynch, modified G7G-Ovsynch (MG7G-Ovsynch) and Ovsynch protocols and to assess the accuracy of using pregnancy-associated glycoproteins (PAGs) and plasma progesterone (P4) in pregnancy diagnosis compared with ultrasonography (US). In study 1, Holstein cows (n = 37) were bred by TAI following the G7G-Ovsynch protocol (n = 19) or MG7G-Ovsynch (n = 18). Pregnancy was evaluated by US at days 31, 59, and 87 after breeding. The PR was not different for the G7G-Ovsynch and MG7G-Ovsynch. Blood and milk samples were collected on day 3 after insemination and then weekly through day 59 post TAI in cows diagnosed as not pregnant on day 31 and through day 87 in pregnant cows. PAGs were measured using ELISA and P4 by radioimmunoassay (RIA). In the second study, Holstein cows (n = 212) were bred by TAI following G7G-Ovsynch protocol (n = 110) or standard Ovsynch (n = 102). Cows were subjected to pregnancy diagnosis on days 30, 60, and 90. A subset (n = 15 in each group) was subjected to blood and milk samples on days 30, 45, 60, 75, and 90 to measure PAGs and P4. In study 2, PR was not significantly different between synchronization protocols on days 30, 60, and 90. Pregnancy loss averaged 15% between day 30 and day 90. The use of PAGs and P4 proved equally effective in diagnosis of pregnancy. Thus, G7G-Ovsynch was deemed the protocol of choice in postpartum cows, and PAGs assayed in milk or plasma could be used to diagnose pregnancy.
