“…Amer (2010Amer ( , 2008 used ultrasound to measure crown-rump lengths and biparietal diameters in pregnant goats and found similar values at 45 days of pregnancy. Oliveira et al (2014), on evaluating the embryonic and fetal development in Canindé goats, found values similar to our study in terms of the diameter of the embryonic vesicle and the crown-rump length for the same period of gestation. At parturition, fecundity was statistically similar (P > 0.05) between the groups, with an overall mean of 1.39 ± 0.11 kids, and there were no differences in the multiple birth rate between groups.…”

The present study evaluates the use of dried carnauba wax palm fruit in 28 postpartum goats fed diets containing Bermudagrass hay and either corn (WCWP) or carnauba-based (CWP) concentrated feed. Estrus synchronization was performed 90 days postpartum, and the goats were mated. In the CWP group, compared to the WCWP group, the daily dry matter intake was significantly reduced (646.48 ± 11.03 g vs. 739.29 ± 3.24 g, respectively; P < 0.01). The time to the first functional corpus luteum was similar between the groups, occurring a mean 66 days postpartum. During estrus synchronization, the CWP group had a decreased sternal subcutaneous adipose tissue thickness when compared to the WCWP group (11.93 ± 0.45 mm vs. 13.69 ± 0.57 mm, respectively; P < 0.05) and a lower pregnancy rate (86.67% vs. 46.15%, respectively; P < 0.02). The embryonic vesicle and crown-rump length growth rates, and the biparietal, thoracic, and abdominal diameters at 45 days of pregnancy were within normal range for goats in both groups. Litter size at birth was similar between the groups at a mean 1.39 ± 0.11. In conclusion, the substitution of corn with dehydrated carnauba wax palm fruit in concentrated feed for postpartum goats showed no positive effects. Reduced feed intake in the does consuming the carnauba diet caused decreased body reserves, which probably resulted in a decreased pregnancy rate in the affected does.

A sincronização de estro foi realizada aos 90 dias pós-parto e todas as fêmeas foram cobertas. No grupo CWP, em relação ao grupo WCWP, o consumo de matéria seca foi significativamente menor (646,48 ± 11,03 g vs. 739,29 ± 3,24 g, respectivamente; P < 0,01). O tempo para o aparecimento do primeiro corpo lúteo funcional foi semelhante entre os grupos, ocorrendo em média aos 66 dias pós-parto. No momento da sincronização do estro, o grupo CWP apresentou uma menor espessura do tecido adiposo subcutâneo esternal quando comparado ao grupo WCWP (13,69 ± 0,57 mm vs. 11,93 ± 0,45 mm, respectivamente; P < 0,05) e uma menor taxa de gestação (86,67% vs. 46,15%, respectivamente; P < 0.02). A taxa de crescimento da vesícula embrionária e do comprimento crânio-caudal, assim como no diâmetro biparietal, torácico e abdominal aos 45 dias de gestação estavam em ambos os grupos dentro do esperado para a espécie em questão. Ao parto a prolificidade não diferiu entre os grupos, com média de 1,39 ± 0,11. Em conclusão, a substituição total do milho pelo fruto da carnaubeira no concentrado fornecido às fêmeas caprinas no período pós-parto não apresentou efeitos positivos. A redução da ingestão da dieta nas fêmeas alimentadas com carnaúba levou a uma diminuição das reservas corporais, a qual provavelmente foi a principal causa da diminuição na tax...

“…Another importance of the determination of the age of pregnancy is to predict the delivery time to avoid problems that occur during the parturition and thus reduce the fetal loss due to dystocia (2). The age of pregnancy in farm animals is estimated depending on the time of insemination, which is considered the zero-day of pregnancy (3). This method is more accurate than other methods to determine the age of the pregnancy.…”

Estimated gestational age is essential for breeding farm animals because pregnant females require special care and nutrition, which varies according to gestation. The study aimed to estimate the gestational age of Shami does by transabdominal ultrasonographic measurement of fetal parameters. Thirty-three Shami does aged 2-2.5 years with confirmed conception dates were used. The does were examined in a standing position using a transabdominal 3.5 MHz convex sector probe of real-time ultrasonography. The does were examined weekly starting on 21 days of pregnancy until parturition. Measurements of the fetal parameters that include; the crown-rump length, head diameter, chest diameter, trunk diameter were obtained from the ultrasonographic images using the software Screen Calipers. Results showed that the gestational sac and embryos were observed first on 21 and 35 days of pregnancy. The litter size of pregnant does range between two and three kids. Crown-rump length ranged between 24.68±1.32 -71.71±1.84 mm on 41-60 days. The head diameter was 15.63±0.82 -45.04±0.92 mm on 41-120 days. Chest diameter was 11.52±0.84 -56.35±0.93 on 51-110 days, and trunk diameter was 10.69±0.85 -57.38±0.85 mm on 41-130 days of gestation. The highest positive correlations were obtained between the gestational age chest diameter (r=0.935), crown-rump length (r=0.917), head diameter (r=0.917) and trunk diameter (r=903). In conclusion, transabdominal ultrasonography is a practical method for pregnancy diagnosis and embryo monitoring in Shami goats. Also, it is reliable to estimate gestation age starting on 41 days of pregnancy. The chest diameter was the best fetal parameter, but trunk diameter can be used for the longest period to estimate the gestational age of Shami goats.
