“…From a clinical standpoint, the 80% pregnancy rate is very similar to the 83-85% reported by Jarrell and Dzink (8) and by Singh et al (17). However, a recent review by Robertson et al (16), reported that conception rates in goats depends on multiple factors and could range widely between 60 and > 93%.…”

“…In 1991, Jarrel and Dziuk (8) reported that blood P4 was higher in goats with multiple corpora lutea from 7 to 30 days of pregnancy, while the number of corpora lutea or of fetuses did not show an effect on plasma P4 concentrations after 30 days of pregnancy. A recent study (17) reported that plasma P4 does not correlate with the number of fetuses during early pregnancy in goats with a relation between fetuses' number and P4 at 51 days of pregnancy. In mid pregnancy, the plasma P4 was greater in does with twins than those bearing singleton pregnancies (18.91 ± 0.67 vs 14.51 ± 0.47 ng/mL) (17).…”

The Teramana goat is an at-risk breed, needing population protection and programs to increase their numbers. The first step for a population increase is the best management of reproduction, leading to an as high as possible number of healthy and viable kids born. To this purpose, beside the optimization of mating, the best possible management of pregnancy and parturition is mandatory. The goat is a prolific farm animal in which single, double, or triple ovulations can occur, leading to singleton, twin or triple pregnancies, and the birth of multiple kids. Twins and triplets are associated to increased risk for perinatal mortality and need a special surveillance and possible assistance at birth. Knowledge of the number of fetuses that have to be delivered from each goat could be a practical tool for a better management of parturition. Among the methods to define the number of fetuses in the goat, the measurement of blood progesterone (P4) concentrations have provided inconsistent results. Therefore, the present study was aimed to assess the possible association between the maternal concentrations of plasma P4 and cortisol (C), two hormones possibly associated to the number of fetuses, measured only once at about two to one week before parturition in Teramana goats, and the number of fetuses. The results, obtained from 23 does, showed that both plasma P4 and C are higher in does bearing multiple fetuses than does with singleton pregnancies. However, the single measurement of plasma C, but not P4, two to one week before the expected parturition in the Teramana goat is useful to distinguish between does bearing singleton and triplet pregnancies for a better surveillance and assistance at delivery. Therefore, it could represent a tool for the best management of reproduction in a breed population at risk for extinction.

“…The strong correlation between E1 and E1S in pregnant American Bison and the low E1 concentrations (in pg/mL) when compared with E1S (in ng/mL) suggest that E1 should be considered as a trace of estrogens metabolism. E1S production has been described in late pregnancy of mares [37] , reindeer [29] , ewes [38] , goats [33] , buffalos [39] , cows [40] , and many other ungulates [41] . Estrogen production in pregnant American Bison was reported in early studies [5] , but without identifying the involved estrogens, and only in feces of a small number of animals with approximative assessment of the pregnancy day.…”

“…The progesterone concentrations at day-63 and day-84 were 12.01 ± 5.30 and 12.04 ± 0.30 ng/mL (p >0.05). Singh et al (2019) reported that during mid-pregnancy (day-50 to day-100), progesterone concentrations were relatively stable in around 12-14 ng/mL. Progesterone concentration in ewes was significantly influenced by the number of corpora lutea found in the ovaries (Hennebold, 2018).…”

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.
