Comparative study of efficacy of prepartum injection of multivitamins and selenium- vitamin E (ά-tocopherol)-combination on post-partum clinical findings, serum steroids, calf and placental weights, and milk antioxidant biomarkers changes in female dromed

Background: All concentrates given to camels were enriched in selenium (Se) in selenite form. The impacts of Se supplementation on lactating female health, milk, and Se/antioxidant statuses received no research interest. Aim: The current study aimed to compare the efficacy of long-term prepartum injection of Se-vitamin E combination and multivitamins on maternal post-calving clinical findings, serum steroid hormones, milk antioxidants, milk somatic cell count (SCC) status, calf body weight, placental weight (PW), and vaginal wash isolates. Methods: From three equal groups of postpartum she-camels (n = 45), one group received no treatment and served as control group (Cont.; n = 15). For 3 months prepartum, one group had received a combination of vitamin E (ά-tocopherol) and Se (VitE-Se-; n = 15), and the third one received multivitamins (Multi-; n = 15). All dams were subjected to clinical and laboratory assays including milk total antioxidant capacity (TAC), Se, vitamin E, and milk SCC on Days 14, 21, and 28 post-calving. Steroid hormones and calf and PW were estimated at birth (Day 0). Results: The study reported higher efficacy of Se-vitamin E combination comparing with that of multivitamins as a long-term prepartum injection in recently calved she-camels that was reflected through significant changes in steroids hormones (Drop), i.e., progesterone (P4) and estradiol (E2), the milk antioxidant biomarkers (Elevation), i.e., TAC, Se, vitamin E, and milk SCCs (Reduction). Both two therapeutic regimens had a more powerful effect that the control one. Conclusion: The applied therapeutic supplements had no significant effect on clinical and hematological changes as well as calves’ body weights and PWs. Body weights were significantly higher in male camel calves than those of female calves either in Cont., VitE-Se-, or Multi-

Impact of GnRH Analogues and Exogenous Progesterone Supplementation in Treatment of Ovarian Inactivity for Primiparous and Multiparous Dromedary She-Camels in Egypt

The present investigations were designed to deal with the problem of ovarian inactivity of Dromedary camel. Twenty she-camels were divided into two equal groups as primiparous or multiparous. The same protocol was applied on both groups which was two doses of Receptal® (10μg GnRH analogue) with 10 days apart and exogenous progesterone (PRID) insertion at day zero and was removed at day 10. Blood samples were taken several days for analysing Follicle-stimulating hormone (FSH), Progesterone (P4) and Estradiol (E2). Also, Follicular Size was measured using ultrasound. Significant differences were obtained in FSH, P4 and E2 along days of treatment. Moreover, multiparous had higher levels of FSH and E2 than primiparous. On the other hand, no significant difference in P4 level was recorded between groups. In general, treatment induced significantly a new follicular wave and stimulates follicle growth from 8.406 mm (day13) up to 12.791 mm (day 15 of PRID insertion), nevertheless, no significance in follicular size between groups was observed. She-camels in both groups revealed a noticed response to treatment protocol which was observed via estrous signs. Pregnancy rate doesn't reveal a significant difference between groups. We can conclude that, a combination of 1.55gm of exogenous P4 and two doses of 10µg GnRH analogues can enhance emergence of follicular development up to pre ovulatory size and significantly alter hormonal profile of primiparous and multiparous she camels with inactive ovaries

Comparative study between efficacy of dexamethasone-prostaglandin-receptal combination and mechanical correction in uterine torsion cases in Egyptian buffalo-cows (Bubalus bubalis)

Abstract Background According to reports, the majority of domesticated species exhibited uterine torsion. It was occasionally noted as a cause of dystocia in buffaloes. The uterus might twist more frequently late in pregnancy because of certain animal traits. The current research monitored the clinical findings and laboratory assays associated with uterine torsion cases in pregnant buffalo-cows through comparing between normal labored buffalo-cows (Norm-Labgr; n = 20), mechanically corrected uterine torsed animals without medicament interference (UtrTorsgr; n = 160), and mechanically corrected uterine torsed animals with medicament interference (UtrTors-Medgr; n = 40) through focusing on placental characterization, calves body weight, milk constituents and milk somatic cell count (SCC) in normal labored buffaloes and uterine torsed ones. Through clinical and laboratory investigations of these buffaloes (N = 220) had been conducted 3 times; 7 h pre-calving and post calving (Post uterine correction) i.e. 48 and 96 h. Uterine torsion prevalence parameters, placental characterization, calves body weight, milk constituents and milk somatic cell counts were evaluated in normal labored buffaloes and uterine torsed ones. Results and Conclusions The study concluded pre-calving remarkable variations in clinical findings, leukogram picture, calf birth weight and some placental characterization parameters between Norm-Labgr and each of UtrTorsgr and UtrTors-Medgr whereas these variations disappeared post-partum as a result to either only mechanical correction or mechanical correction plus medicaments interference. No pre-or post-calving significant changes between UtrTorsgr and UtrTors-Medgr except for the abnormal clinical findings were more representative in UtrTors-Medgr than those in UtrTorsgr particularly pre-calving. The applied pre-calving therapeutic regimen including dexamethasone-prostaglandin-receptal combination had a powerful potential efficacy that induced vaginal delivery of calves in UtrTors-Medgr as well as prepartum mechanical correction of torsed uterus approved higher efficacy in UtrTorsgr. The applied prepartum mechanical correction of torsed uterus and/or pre-calving therapeutic regimen as well as subsequent post-calving, post uterine correction applied medicament treatment accelerated rapid recovery of affected buffalo-cows through achieving rapid restoring of their physiological parameters. Buffalo-cow’s milk composition, milk pH and milk SCC were not affected whereas no significant variations were reported between Norm-Labgr, UtrTorsgr and UtrTors-Medgr
