Abstract

This study aimed to determine the progesterone concentrations of Ettawa crossbred does at day-0, -21, -42, -63, and -84 after mating. Five Ettawa crossbred does were injected with PGF2α twice with an interval of 11 days for estrous synchronization followed by natural mating on day-3 after the second PGF2α injection. Blood was collected through the jugular vein for the measurement of serum progesterone concentrations using ELISA, whereas pregnancy was diagnosed at 90 days after mating by abdominal palpation. The results showed that all does were on estrus onthethird day after the second PGF2α, three of them diagnosed to be pregnant following mating. The progesterone concentration at day-0 was 1.52 ± 0.33 ng/mL, increased (p <0.05) to 7.08 ± 1.02 and 5.50 ± 2.82 ng/mL at day-21 and day-42, and increased (p <0.05) again to 12.01 ± 5.30 and 12.04 ± 0.30 ng/mL at day 63 and day 84, respectively. There was no significant difference in progesterone concentrations between day 21 and day 42 and between day 63 and day 84. It could be concluded that there was a biphasic increase of progesterone concentrations of the pregnant Ettawa crossbred does, i.e. from day-0 to day-21/day-42 and from day-21/day-42 to day-63/day-84.

Abstract

Small farmers dominate dairy farming in Indonesia, and the average productivity is low. The contribution of domestic production only reaches about 23% of the total national milk consumption needs as a source of human nutrition. This study was aimed to identify the relationship between cow's parity and  age to services per conception (S/C), conception rate (CR), and gestation length (GL) of Holstein Friesian (HF) cross dairy cows. Data of this study consisted of primary data obtained from farmers interview, and secondary data from the Cooperative Unit of Argopuro village, Krucil, Probolinggo. Sample size was 200 cows, which was 10% of the total population. Data were analyzed for correlation and linear regression using the Statistic Package and Service Solution (SPSS) software version 20 (IBM Corp., USA) at a 95% confidence level. The average S/C, CR, and GL were 2.55 ± 1.57, 21%, and 278.19 ± 11.92 days, respectively. There was no significant correlation (p >0.05) between the parity with S/C, CR, and GL and the age with CR and GL. The only significant correlation (p <0.05) was between the age and S/C. Regression of S/C based on age followed the equation S/C = 0.104 + 0.407*age, with a correlation coefficient and determination coefficient of 0.733 and 0.538, respectively. It could be concluded that S/C could be predicted based on the age of the cows.
