“…Zinc plays an essential role in sexual development and is also involved in reorganization of ovarian follicles that produce progesterone (Yatoo et al, 2013). Reproductive events (e.g., estrus, pregnancy, and lactation) and particularly the onset of estrus in females are affected by zinc (Amin et al, 2016). Iron is also essential for optimal ovarian activity (Qian et al, 2001).…”

“…Yatoo et al (2016) reported positive correlations between the levels of Fe, Zn, and Mn and progesterone in heifers. In contrast, macronutrients Ca, P, and Mg alone typically do not directly affect the reproductive status of animals, even though the disturbances in Ca-P-Mg homeostasis can have some effects on reproduction (Amin et al, 2016;Ullah et al, 2010).…”

Inadequate feed intake and nutrient supply are associated with the suboptimal reproductive performance of Kacang goats reared using a traditional tethering system in the Pariaman region of Indonesia. The objectives of this study were to (i) identify reproductive problems in tethered female Kacang goats, (ii) assess crude nutrient and mineral composition of feed consumed by tethered goats, and (iii) evaluate the beneficial effects of mineral supplementation on reproductive performance of tethered female Kacang goats. A field survey was carried out in Pariaman City and the Padang Pariaman Regency to collect data on reproductive performance as well as blood mineral and hematological profiles of tethered female Kacang goats. Forage and feed samples were collected and analyzed for dry matter (DM), crude protein (CP), and minerals (Ca, P, Mg, Fe, Cu, and Zn) contents. Feed was formulated with supplemented complete minerals in either block form or mixed with feed. A total of 15 young female Kacang goats received feed without supplement (P0, n=5), or mineral supplement with feed (P1, n=5), or in a manually prepared block lick (P2, n=5). Parameters measured included body weight, number of pregnant goats, blood mineral concentrations, hematological parameters, total protein concentrations, and progesterone concentrations. Results of the field survey showed that the age of maturity of female Kacang goats reared under a tethering system ranged between 5 and 9 months and the first kidding occurred between 12 and 23 months. The suboptimal reproductive performance of female Kacang goats raised using a tethering system was closely related to the inadequate feed intake and nutritional deficiency. Supplementation with minerals is an effective method to enhance nutritional status and health to increase pregnancy rate of tethered female Kacang goats.

“…Oral administration of a polyherbal formulation significantly improved the secretion of reproductive hormones, namely, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and sex steroid hormones, and also improved the spermatogenic activity in oligospermic infertile men [43]. From the viewpoint of nutrition, it is necessary to maintain the normal levels of macroelements and microelements for reproductive function in dairy cattle [44,45]. Such maintenance was probably achieved by the addition of the essential macroelements such as calcium and phosphorus present in M. pterygosperma [13], microelements (trace elements) such as copper and manganese present in C. rotundus [10], and iodine present in the rhizome of Z. officinale [14].…”

Background and Aim: The reproductive performance of dairy cows is of a high economic value to maintain efficient and sustainable productivity. Postpartum anestrus is one of the major infertility problems that cause limitation of dairy cow reproductive performance and productivity. The previous studies have reported using a polyherbal formulation for different purposes, including reproductive performance. This study was conducted to examine the efficacy of polyherbal formulation administration on the reproductive performance of cows and to establish the oral administration of polyherbal formulations as a safe, effective, and economic treatment for dairy cows with postpartum anestrus due to nutritional disorders, negative energy balance, high milk production, and/or heat stress. Materials and Methods: A total of 14 dairy cows with postpartum anestrus were randomly divided into two groups, which were subjected to oral administration of distilled water that served as the control (Ctrl; n=5) or polyherbal treatment (polyherbal treated; n=9) for two shots of treatment (each for 3 successive days) with a 10-day interval. Blood sampling and ultrasonography were performed before treatment and after the first and second shots of treatment. Progesterone (P4) assay was also performed. Results: The estrus induction rate was 66.7% after the first shot of treatment in the polyherbal-treated group, which increased significantly to 88.9% after the second shot of treatment, compared with the Ctrl group (20%). The estrus response was confirmed by ultrasonography and P4 hormone assay, wherein the polyherbal treatment significantly increased the P4 concentration in the polyherbal-treated group after the second shot of treatment compared to that before treatment and in the Ctrl group at all time points. On pregnancy diagnosis, the treated dairy cows showed conception rates of 66.7% and 20.0% in the polyherbal-treated and Ctrl groups, respectively. In contrast, the concentration of malondialdehyde, an oxidative stress marker, and the total antioxidant capacity remained unchanged between both groups before and after treatment. Conclusion: The polyherbal formulation containing tubers of C. rotundus, M. pterygosperma, rhizome of Z. officinale, and A. cepa has the potential to induce estrus response and luteal activity in dairy cows and is a possible treatment for ovarian inactivity in dairy farms.

“…Trace elements are necessary for maturation of the oocyte and maintaining the number of stored follicles at their normal range through their inevitable role in gonadotropins secretion (Chavarro et al, 2006;Singer et al, 2011). As a key player in the biosynthesis of cholesterol, they are irreplaceable for steroidogenesis and subsequent regulation of the folliculogenesis in female animals (Amin et al, 2016). Accordingly, animals receive trace elements-deficient diets are prone to failure of oogenesis, increased follicular atresia, inadequate steroidogenesis, ovulation failure and CL persistence (Gürdoðan et al, 2006;Vázquez-Armijo et al, 2011;Grace and Knowels, 2012;Ceko et al, 2016).…”

“…The normal requirements of trace elements increase greatly during pregnancy and adequate supply is of utmost importance before intended breeding to prepare the animal for the sequences of pregnancy and associated physiological changes during this period. Trace elements are involved in the growth, development and normal evolution of the pregnant uterus and its contents (Amin et al, 2016). Their roles in the enzymatic activity, efficiency of the immune system, the buildup of antioxidant capacity, integrity Trace Elements in Pregnant and Non-pregnant Sheep and Goats and Their Relation to Steroid Hormones of the inner lining of the reproductive organs are nonnegotiable (Uslu et al, 2017).…”

Background: One of the major factors affecting the physiology of pregnancy and reproductive cycle is the trace elements intake and their levels in serum of brood ewes and does. The main objective of this investigation was to study the association between serum concentration of trace elements, ovarian findings, stage of pregnancy and steroid hormones in sheep and goats. Methods: Total of 129 ewes (68 pregnant and 61 non-pregnant) and 54 does (32 pregnant and 22 non-pregnant) were examined clinically and ultrasonographically for pregnancy diagnosis and monitoring the ovarian findings. Pregnant animals were categorized according to the gestational stage into 1 to 2, greater than 2 to 3, greater than 3 to 4 and greater than 4 months. According to the ovarian findings, non-pregnant animals were categorized as having mature corpus luteum (CL), large follicle ( greater than 5 mm) and corpus luteum (CL+F), growing follicles (GF, less than 5.mm) and mature follicle (MF, greater than 5 mm). Animals were bled and serum was harvested and assayed for estrogen (E2), progesterone (P4), manganese (Mn), selenium (Se), iron (Fe) and zinc (Zn) levels. Result: Mn (P=0.01), Fe (P=0.05) and Zn (P=0.001) were lower in pregnant compared with non-pregnant ewes. Fe was significantly higher (P=0.03) in non-pregnant compared with pregnant does at any gestational stage. Ewes with MF had higher Se (P=0.02) and Fe (P=0.001) compared with other ewes. Fe (P=0.001) and Zn (P=0.000) were higher in does having MF compared with other does. A positive association between E2 and serum Fe in non-pregnant ewes (P=0.03) and does (P=0.05) was found. It can be concluded that pregnancy associated with a decrease in serum trace elements in sheep and goats.
