Mineral an Important Nutrient for Efficient Reproductive Health in Dairy Cattle
2017
Apart from energy and protein, mineral constitutes a major role in production and reproduction of animals. Deficiencies of certain mineral elements may cause reproductive disorders as minerals play an important role in health and reproduction of the livestock. Infertility and reproductive disorders has emerged as an important problem in our livestock population. Adequate supplementation of minerals depends on age, stage of pregnancy and lactation. Macro minerals and trace minerals are equally important as they take part in formation of structural component of body and proper functioning of enzymes, hormones, vitamins and cells. Mineral deficiency and toxicity is area specific. Minerals have beneficial or detrimental effects on animal physiological wellbeing, depending on its balance.
IJSRST162117 | Effects of Macro and Micro Minerals on Reproduction in Dairy Cattle A Review
Minerals are very important nutrients for dairy animal production. Deficiency of minerals may leads to certain structural, physiological or immunological disorder affecting growth, production and reproductive health of animals. Minerals deficiency is an area specific problem and supplementation strategy must be revised accordingly. In dairy cows, minerals requirements are influenced by several factors including age, stage of pregnancy and stage of lactation. Requirements of minerals for reproduction and immunity are generally higher than maintenance requirement of animals. Supplementation of minerals requires correct knowledge of bioavailability, sources, requirement of animal and mineral interactions with other nutrients. Current review highlighted the recent updates on mineral requirements of dairy animals for reproduction with special reference to their requirements, metabolic functions and mineral interactions.

This study evaluated the effect of injecting trace minerals on reproductive performance in overconditioned Holstein cows before synchronized estrus. Multiparous non-lactating, over-conditioned repeat breeder cows (n = 20) were assigned randomly to one of two treatments: 1) control (n = 10), and 2) supplementation with an injectable trace mineral complex 25 days before expected synchronized estrus (n = 10). Follicular waves were synchronized by intravaginal insertion of a CIDR for eight days and an intramuscular (i.m.) injection of a GnRH analogue. Estrus was induced at CIDR removal by an i.m. injection of PGF 2α. Blood samples were collected before and after synchronized estrus. The response variables were follicle population (FP), diameter of the preovulatory follicle at CIDR removal (DFP0) and at estrus detection (DFP1), time of estrus after CIDR removal (TE), area of corpus luteum (ACL), pregnancy rate and copper and zinc serum concentrations. The statistical analysis of the variables was carried out with SAS. The FP, DFP0, DFP1, TE, ACL and serum concentrations of copper and zinc were not affected by the trace mineral injection (P > 0.05). Even though pregnancy rate at 40 (77.78 ± 13.46 vs 44.44 ± 16.56%) and 60 days after AI (66.67 ± 15.71 vs 33.33 ± 15.71%) was numerically higher for cows injected with trace minerals than for the control group, the differences were not significant (P > 0.05). In conclusion, while follicular and corpus luteum development were not affected by trace mineral injection, it may be a feasible way to increase the pregnancy rate in over-conditioned cows.
Minerals and its impact on fertility of livestock: A review
Agricultural Reviews, 2016
Minerals are essential for growth and reproduction of the livestock. The deficiency of the macro and micro minerals have a great impact on animal’s reproductive physiology and its imbalance causes various problems leading to lowered reproductive efficiency. Adequate minerals supplementation is required as most of the roughages, greens, concentrate and even most of commercial feeds are deficient in trace mineral elements. The best recommendation at present is to provide a feeding program for productive animals which is balanced for all minerals and meets all known requirements.

The paper presents data regarding the status of some important bioelements for the bovine fertility when a mineral supplement was added to a normal fertility protocol in cattle and the influence of this upon the fertility percentage. The study was made on sixty Romanian Spotted cattle 18-19 months old divided randomly in four groups as follows: C-Control, and three experimental groups E1-E3, that received a normal fertility protocul with Ovarelin (GnRh) in day 1 and day 10, Enzaprost (PGF2α) in day 7. E1 received in plus Sel-E-Vit (Selenium+Vit.E), E2 received Mineral TS and E3 Sel-E-Vit + Mineral TS. The cattles were blind artificial inseminated in day 11 and gestation diagnosis was performen by ultrasound method in day 55 and the percentage of fertility was analyzed. Blood samples were collected in day 0 and day 12 for trace elements analisys by AAS flame and furnace method. Were measured the serum levels of iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), and selenium (Se). In all experimental groups in day 0 were not significant (P≥0.05) differences regarding the studied trace elements. In day 12 we observed a significant increase of Se and Fe in E2 and E3 groups and of Cu in E2 group comparative to controol. On the other hand was recorded a significant decrease of Zn and not significant decrease of Mn in all experimental groups comparative to control. The conception rate and percentage of fertility was higher in E1 followed by E2 and E3 groups comparative to control. We can conclude that the introduction of a mineral supplement, in our case Mineral TS, could increase the the conception rate and fertility percentage in cattle.

To assess the effect of area specific mineral mixture and hormonal therapy on growth, blood chemistry and mineral status of the reproductive disorder cross-bred cattle of Kalahandi district of Odisha, 80 animals (52 cows, 28 heifers) were selected and divided into four groups of 20 animals each (containing both anoestrus and repeat breeder) in which treatment was performed for 60 days. Group I: control (farmer practice), group II: group I + area specific mineral mixture @ 50 g/animal/day, group III: group II + hormone (double synch), and group IV: group II + hormone (Estra double synch). The growth performances were measured in terms of body weight and average daily gain (ADG). Blood collection was done at the start and end of the experiment for assessment of blood biochemical and mineral status of the animals. Results revealed significant (p< 0.05) improvement in growth, serum glucose and mineral status of treated animals as compared to control animal.

To study the effect of area specific mineral mixture on the haemato biochemical, serum minerals and ovarian status of crossbred cattle, forty reproductive disordered animals were selected and divided into two groups having 20 animals each. Group I was kept as control (farmer practice) and Group II: Group I + mineral mixture (50 g/day/animal). Treatment was conducted for 60 days. Haemato-biochemical and mineral profile were assessed for the analysis of the reproductive status of the animals. Ovarian status and pregnancy detection of animals were regularly monitored. Among blood biochemical's, only serum glucose and total protein level were increased significantly (P<0.05). All minerals concentration was found to be highest in mineral supplemented group compared to that of control. In the treated group the numbers of functional ovaries were effectively increased in heifers and repeat breeders as well as conception rate as compared to control group. So Supplementations of area specific mineral mixture enhanced the haemato biochemical, mineral and ovarian status in repeat breeding animals as well as eliminate the anestrous problem in crossbred animals.
Reproduction in Domestic Animals, 2020
Globally, contribution of livestock production has a significant influence on agricultural growth (Randolph et al., 2007). Nutrient requirements increase as the pregnancy progresses and failure to account for nutritional demands during this period can affect reproductive performance and foetal growth (Caldow & Riddell, 2015). Minerals, in particular, are greatly essential, as any alteration in supply during gestation can predispose cows to reproductive failure (Andrieu, 2008; Griffiths, Loeffler, Socha, Tomlinson, & Johnson, 2007). In mammals, reproductive needs for minerals are commonly consistent with the foetal, conception product (i.e. foetal fluid, uterus and placenta) and mineral content (Suttle, 2010). Deficiencies in calcium, magnesium, phosphorus, copper, selenium, zinc and manganese have been associated with occurrences of hypocalcaemia, retained placenta, abortion, dystocia, vaginal
The Interactions of Some Minerals Elements in Health and Reproductive Performance of Dairy Cows
IntechOpen eBooks, 2022
The dairy business is recognized as an important economic and nutritional resource. The food and agriculture organization (FAO) estimates that there are about 245 million dairy cows in the world. Milk production offers enormous health, sociological, and economic benefits around the world. In emerging economies, livestock serves a range of purposes, including providing a source of household income, a financial asset for women, food security, risk management, and a direct connection to human health. With a total value of $628.27 billion USD in 2018, the dairy industry provides a major economic impact. The dairy business supports over a million employment, either directly or indirectly. In terms of public health, the dairy business plays a role. While dairy products are a beneficial part of a balanced diet, zoonotic and food-borne diseases originating in dairy animals can be dangerous to humans. Milk production performance in emerging countries is poor. Non-infectious infertility in dairy cattle is most commonly caused by energy, protein, and mineral deficiencies. According to the current review, minerals, play an essential role in animal production and reproduction issues. This chapter discusses the linkages of several mineral elements in health and reproductive performance that affects the dairy industry.

The investigation was expected to assess various mineral mixture supplementation impacts on Brahman crossbred cows' blood biochemical, hematological profiles and pregnancy rate. This study used ninety Brahman crossbred cows divided into three dietary treatment groups (n = 30/group). The dietary treatments were: Concentrate and rice straw only as control treatment; control diet + mineral mixture A-formulation as MM-A treatment; and control diet + mineral mixture B-formulation as MM-B treatment. The concentration of MM-B (including calcium, phosphor, cobalt, copper, sulphur, potassium, zinc, manganese, magnesium, sodium, selenium and iron) was higher than MM-A. The mineral mixture was added to 0.5 kg/100 kg of diet. The concentrate mix and rice straw were restricted to 3 kg and 20 kg/day (as-fed basis). Feeding treatment was conducted until four months. Blood sampling and estrous synchronization were carried out after three weeks of dietary treatments. The estrous synchronization aimed to equate the estrous cycle of each cow by using 25 mg prostaglandin F2α (Lutalyse™) (injection via intramuscular). Estrous signs were observed two days after synchronization. Artificial insemination was conducted at ten to twelve hours from estrous detection, inseminated with post-thawed frozen Belgian Blue bull sperm. Transrectal palpation was used to diagnose the cow's pregnancy 90 days after artificial insemination. The serum samples were analyzed for blood biochemical, hematology and mineral status. The results showed that MM-B supplementation significantly increased (p<0.05) serum calcium, phosphor, selenium and iron. There were no significant differences in serum glucose, total protein, albumin, cholesterol, triglyceride, creatinine, uric acid, blood urea nitrogen and hematological profile. The pregnancy rate in MM-B treatment was higher than MM-A and control treatment. The pregnancy rate in the MM-B treatment (20.7%) was higher than control (6.67%) and MM-A treatment (3.33%). It was concluded that mineral mixture supplementation improved the pregnancy rate and several blood components on Brahman Crossbred cows.
