Blood biochemical and hormonal profiles vis-a-vis production performance of single and twin kid bearing Surti goats (Capra hircus)

Abstract

Study was undertaken to investigate the effect of single and twin kidding on blood bio-chemical, hormonal profiles and production performance of 14 goats. The animals were divided into group1 (single kid, n=7) and group 2 (twin kids, n= 7). The blood samples were collected on 0, 7, 15, 30, 45 and 60 day of parturition for analysis of blood profiles. Milk yield and fat% were also recorded on different test days. Serum glucose, albumin, BUN and cholesterol was higher in twin bearing dam; however, it was not significantly (P<0.05) different. Overall total protein and NEFA was higher in singlet bearing goats on 0 and 45 days of parturition. Cortisol was significantly (P<0.05) higher in singlet bearing goats initially (7d) during kidding, however overall cortisol level was higher in twin bearing dams, indicating fast recovery of stress in singlet bearing goats. Level of estrogen was also higher in twin bearing goats. Milk yield was significantly higher in twin bearing goats. It was therefore inferred that kidding pattern had a marked influence on blood profiles and production performance in Surti goats.

Steroid hormonal endpoints in goats carrying single or twin fetuses reared in semi-extensive systems

“…The overall mean E 2 , P 4 , and cortisol ranges recorded in this study are in accordance with the physiological ranges reported by different authors for clinically healthy nonpregnant, pregnant, and postpartum goats (Gamit et al, 2019;Khan and Ludri, 2002c;Probo et al, 2011;de Souza Castagnino et al, 2015;Tharwat et al, 2013). Nevertheless, some variation might be due to differences in the techniques used (Barth et al, 2018), the experimental model, diet, management, the physiological period, and genotype.…”

“…In the present study, we found the significantly highest values of both E 2 and P 4 in the whole pregnancy compared with the prior and following periods, consistently with an increased demand for a higher metabolic rate for pregnancy, previously observed in dairy goats (de Souza Castagnino et al, 2015). This trend might happen due to the preparation of the reproductive system for the growth of the uterus and fetus, as previously recorded for goats (Capezzuto et al, 2008;Gamit et al, 2019;Laura et al, 2004). On the other hand, the significant decrease in E 2 and P 4 in early lactation may also reflect a difference in nutrient availability and the related utilization in a catabolic or anabolic manner: this may temporarily change the metabolic requirements to cope with an intensive lactogenesis phase.…”

“…The corpus luteum is the only source of P 4 for the physiological maintenance of pregnancy in goats and an increased number of corpora lutea may induce a greater P 4 and E 2 secretion, leading to the stimulation of mammary gland growth in goats carrying twin fetuses (Khan and Ludri, 2002b). Nevertheless, in Surti goats no significantly higher E 2 values were observed in twin gestations than single-bearing mothers (Gamit et al, 2019). On the other hand, a low level of E 2 was recorded in twin compared to single pregnancy in crossbred goats by Khan and Ludri (2002a).…”

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

“…Higher level (overall 11.59% or higher) of estrogen was observed in twin pregnancy in Surti goats as compared to single-bearing goat on all test days although it was not significant [ 26 ]. This increase is also physiological, as estrogen is required for uterine contractions during parturition.…”

Postnatal hypoglycemia and blood glucose concentrations in neonatal tropical goat kids

“…13 In addition, higher blood glucose concentrations at birth than at day 15 postnatal in Surti goat kids and day 28 postnatal in Saanen goat kids have been reported. 40,41 The significantly higher incidence of neonatal hypoglycemia in RSG and SHG kids in the current study suggests a genetic predisposition due to breed differences, which might influence either the ability of the neonatal kids to accumulate energy reserves (glycogen and fatty acids) during gestation or prompt release of accumulated energy reserves immediately after kidding. 9,10,42,43 This could be associated with a variation in the ability of the dams to take up, use, and make dietary nutrients available to the fetus for maintenance and storage during gestation.…”
