“…Nevertheless, more from the body reserves fulfills the maintenance energy requirements of the goat. As previously stated, we observed that this mobilization is concentrated in the final third of pregnancy (Khan and Lundri, 2002), which can be verified by the increasing levels of serum NEFA and ß-hydroxybutyrate during this phase.…”

-The objective of this study was to evaluate the mobilization of nutrients in goats of different gestation types and pregnancy stages. Forty-four Saanen and Oberhasli goats were studied. The goats of each breed and gestation type (single or twin) were slaughtered at different gestational ages (80, 110, and 140 days of pregnancy), forming a completely randomized design in a 2 × 3 × 2 factorial arrangement (two breeds, three gestational ages, and two types of pregnancy). The slaughter procedure involved separating the empty body, mammary glands, uterus with membranes and fetal fluid, and fetus(es). For the females slaughtered at 140 days of pregnancy, blood was collected to analyze metabolites and hormones every 15 days during gestation. The dry matter (DM) intake was lower in goats with twin pregnancies. The relative daily retention rate of the nutrients in the body was positive at 100 days of pregnancy but became negative at 140 days (-0.18±0.25 g DM kg -1 of maternal body d -1) and did not differ with breed or number of fetuses. Fetal growth in twin pregnancies was 66% higher than in single pregnancies. The highest levels of ß-hydroxybutyrate and non-esterified fatty acids were observed beginning at 100 days of gestation. Serum total protein and albumin levels decreased after 125 days of gestation. Serum urea levels were reduced after 80 days of gestation. Plasma 17ß-estradiol levels increased with the advance of pregnancy, and IGF-1 was highest between 60 and 80 days of gestation. The maternal metabolism throughout pregnancy does not vary with the type of pregnancy, and pregnant goats need greater nutritional intake during the final third of the gestational period regardless of the breed or type of pregnancy.

“…Similarly, greater (P<0.01) concentration of insulin was reported in nonlactating than in lactating ewes (Hatfield et al 1999). The results of the present study are in general agreement with Khan and Ludri (2002) who reported low plasma insulin concentrations on the day of kidding in goats.…”

“…T 4 levels were found to be low during the early lactation period in cows with severe fatty liver (Stojic et al 2001). The lowest levels of plasma T 4 on the day of kidding compared to postpartum period have been reported by Khan and Ludri (2002). The results of the present study are in accordance to those of Rasooli et al (2004) who observed that cold environment may be a stimulus to increase the thyrotrophic hormone output thereby resulting in a higher concentration of thyroid hormone in serum.…”

In order to study the plasma hormonal and metabolic changes in Zebu (Sahiwal) cattle during summer and winter season, five each of periparturient high and low yielding cows were selected from Livestock Research Centre, ICAR-NDRI, Karnal. Blood samples were collected on days -45, -30, -15 (prior to parturition), 0 (day of parturition) and 15, 30, 45 (postpartum) during both the seasons and plasma was separated. Plasma cortisol levels were significantly higher on day of parturition and during postpartum period in both the groups during both the seasons. Plasma insulin levels were significantly (P<0.05) lower during summer in high yielder group. On the day of calving, plasma T 3 and T 4 levels were significantly (P<0.05) lower in high yielders during both seasons. Plasma leptin levels were lower (P<0.05) on day of parturition in high yielders than low yielders during both seasons. Plasma glucose levels were significantly lower (P<0.05) on day of parturition and remained low during postpartum period in both groups during both seasons comparel to prepartum period. Plasma NEFA levels of both groups of cows were higher on the day of calving and remained higher during postpartum period over pre calving values. High yielder cows showed more deviation in stress markers viz. cortisol and NEFA than low yielder cows. Therefore, special attention should be given to feeding and management of the lactating animals (especially high yielding cows during summer) around parturition for sustained productivity and maintenance of homeostasis.

“…Prepartum surge in estrogen on day of kidding is essential for starting parturition, i.e., uterine contraction and providing sympathetic stimulus for oxytocin and triggering prostaglandin release for myometrial contraction. However, low level of estrogen was reported in twin pregnancy as compared to singlet pregnancy in crossbred goats [ 28 ]. The decline in progesterone concentration is physiological due to the destruction of the corpus luteum of pregnancy and the decreased level of progesterone released from the placenta [ 28 , 29 ].…”

Changes in plasma biochemical parameters and hormones during transition period in Beetal goats carrying single and twin fetus

2020

Aim: The study was undertaken to find out the changes in biochemical and hormonal profile during transition period in single- and twin-bearing Beetal goats. Materials and Methods: Beetal goats are reared in North India for milk and meat purposes, popularly called poor man's cow, serving as a source of livelihood. The present study was conducted on Beetal goats, maintained at a goat farm, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar, for characterization of plasma biochemical and hormonal changes during transitional phase in pregnant goats carrying single and twin fetus. The animals selected were expected to have parturition at the same time, to avoid environmental variation effects, and divided into two groups: Group 1 (carrying single fetus, n=14) and Group 2 (twin fetus, n=6). Blood samples were collected from goats prepartum (–30 days and –15 days), 0 day, and postpartum +15 days and +30 days, and plasma was separated for the analysis of biochemical metabolites and hormones by commercially available kits. Results: Analysis of data revealed a significant decrease in triglyceride and cholesterol concentration during postpartum days. A significant increase in alanine aminotransferase (ALT) concentration was observed at the day of parturition. Furthermore, there was a significant (p≤0.05) decrease in ALT and aspartate aminotransferase concentration in goats at the 15th day and 30th day after parturition in both groups. A significant (p≤0.05) lower concentration of total protein and globulins was observed during late pregnancy and on the day of parturition, with a subsequent elevation during postpartum period (15 days and 30 days). Progesterone concentration was highest at –30 days prepartum and decreased sharply at parturition and thereafter postpartum, both in single- and twin-bearing goats. Progesterone level was lower in twin-bearing goats as compared to single-bearing goats at 0 day and postpartum days. No significant changes were observed in sodium, potassium, and chloride concentration during transitional period in goats. Conclusion: Transition period blood metabolite profile changes due to physiological need of mother and fetus were more prominent in metabolites regulating energy requirements and in goats bearing twin fetus.
