The objective of this experiment was to evaluate the impact of trace mineral supplementation on reproductive performance in lactating beef cows. Thirty days before AI (Day –30), 68 postpartum cows were stratified by weight, body condition score, and parity before being equally and randomly assigned to either a treatment or a control group. Each group received a weekly mineral supplement allotment of 1.2 kg/week per cow-calf pair for 15 weeks. Cows in the treatment group received a mineral supplement that contained zinc, copper, and manganese amino acid complexes as well as cobalt glucoheptonate (Availa® Plus; Zinpro Corp., Eden Prairie, MN, USA), whereas cows assigned to the control group received a mineral supplement that contained the same concentrations of these trace minerals from inorganic sources. All cows were submitted to a 7-day CO-Synch + CIDR protocol on Day –10 and bred using fixed time AI on Day 0. Pregnancy diagnosis was performed via transrectal ultrasound on Day 28. Cows diagnosed as nonpregnant were then removed from the experiment. Pregnant cows were divided into 10 groups of 3 or 4 cows per group: 5 treatment groups (20 total cows) and 5 control groups (18 total cows). On Day 52 and 67, all pregnant cows were subjected to an ovum pick-up (OPU). Collected oocytes were evaluated before performing in vitro fertilization. Number of oocytes cleaving (dividing into more than one cell) and developing to blastocyst stage was recorded. Analysis of variance was conducted using PROC GLIMMIX (SAS 9.4; SAS Institute Inc., Cary, NC, USA) to determine differences between treatment and control, and group was the experimental unit. Mineral consumption did not differ (P = 0.48) between treatments (average of 1.16 ± 0.065 v. 1.09 ± 0.065 kg/week per cow-calf pair, for treatment and control, respectively). Pregnancy per AI was numerically higher in mineral-supplemented cows versus controls (64.7% v. 52.9%, respectively; P = 0.33). Consumption of the complexed trace mineral supplement increased (P = 0.06) total oocyte yield (22.6 ± 1.44 mean ± SEM v. 16.4 ± 2.04 oocytes/group for treatment and control, respectively). Moreover, groups receiving the complexed trace minerals had more (P = 0.05) culturable oocytes (grades A through C) compared with control groups (15.9 ± 1.6 mean ± SEM v. 11.8 ± 1.01 oocytes/group, respectively). In addition, production of transferable embryos (grades 1 through 3) was greater (P = 0.04) for groups receiving complexed trace minerals than inorganic trace minerals (4.2 ± 0.64 mean ± SEM v. 2.6 ± 0.65 embryos/group, respectively). In summary, supplementing with zinc, manganese, and copper amino acid complexes plus cobalt glucoheptonate improved oocyte production and embryo development in pregnant beef cows when compared with cows supplemented with inorganic forms of these trace minerals.

Abstract Three experiments were conducted at separate locations to determine the effects of a trace mineral injection (TMI), Multimin 90, on heifer performance and reproduction. In Exp. 1, [spring-born, Angus, n = 93, body weight (BW) = 428 ± 45.2 kg], Exp. 2 (spring-born, Angus × Simmental, n = 120, BW = 426 ± 54.0 kg), and Exp. 3 (fall-born, commercial Angus, n = 199, BW = 345 ± 39.7 kg) heifers were stratified by BW within experiment and assigned to 1 of 2 treatments: a control, saline injection, or TMI at a dose of 1 mL/68 kg BW. Free choice mineral, containing Cu, Mn, Se, and Zn formulated to meet or exceed NRC recommendations, was supplemented to heifers. Injections were given 33 d prior to breeding at the initiation of a 14-d controlled internal drug release (CIDR)-prostaglandin protocol. There was no difference (P ≥ 0.37) in BW during Exp. 1. Additionally, there was no difference (P ≥ 0.52) in body condition score (BCS) at initiation or at artificial insemination (AI) and final pregnancy confirmation in Exp. 1; however, a greater (P = 0.03) BCS was noted for control heifers at breeding. Pregnancy rates to timed AI and overall pregnancy rates were also similar (P ≥ 0.74) regardless of treatment. During Exp. 2, BCS and BW did not differ (P ≥ 0.44) across treatments. There was a tendency (P = 0.07) for TMI heifers to have an increased AI pregnancy rate (62 vs. 45%) compared with control heifers despite no difference (P = 0.51) in overall pregnancy rate. In Exp. 3, BW was not different (P ≥ 0.39) across all time points. Also, BCS did not differ (P ≥ 0.45) at initiation, AI, or final pregnancy conformation. Interestingly, there was a tendency (P = 0.10) for TMI heifers to have an increased BCS at the time of breeding compared with control heifers. However, there were no differences (P ≥ 0.50) in AI and overall pregnancy rates. In 1 of 3 experiments, an injectable trace mineral administered 33 d prior to the breeding season in conjunction with a 14-d CIDR protocol, tended to increased AI conception rates of heifers even when adequate trace mineral supplement was provided. The variable response observed across experiments may be caused by differences in breed, calving season, mineral sources, and management strategies.

We determined whether trace mineral supplementation prior to embryo collection affected embryo production and quality. Twenty half-sibling, Angus heifers originating from a common herd were assigned to three treatment groups using a 3×3 latin square design and three rotations of the treatments: (1) heifers received no added mineral to their diet (Control;; n=53); (2) heifers received a commercially available organic mineral supplement (Organic;; Albion Cattle Breeder Pak, Des Moines, IA, USA;; n=52); and (3) heifers received an isomineral, all inorganic mineral supplement (Inorganic;; Inorganic Breeder Pak, Albion, Des Moines, IA, USA;; n=55). All heifers had ad libitum access to hay and were fed a supplement containing corn and soybean meal. Heifers received a 25-mg injection of PGF on Day −23 at which point individual feeding of the corn/soybean/mineral supplement was initiated and fed at recommended levels until the day of embryo collection. All heifers were monitored for signs of estrus, but regardless, all heifers received a 1-mg injection of estradiol cypionate (ECP;; Pharmacia, Kalamazoo, MI, USA) and a CIDR (Pharmacia) on Day −16. From Day −12 to Day −8 heifers received 29mg of follicle stimulating hormone (pFSH, batch 9109, Sioux Biochemical, Sioux Center, IA, USA) in a twice daily decreasing dose schedule. On Day −9 heifers received two 5-mg injections of PGF (AM and PM) and the CIDR was removed in the PM. All heifers were inseminated artificially at 36, 48, and 60h after CIDR removal. On Day 0, embryos were recovered using a nonsurgical procedure and were evaluated under a stereomicroscope. Heifers were given a 45-day adaption period of no mineral supplementation before initiating a new treatment as above. On Days −12, −7, and 0, ovaries were scanned via transrectal ultrasound to determine the presence and number of follicles and CL in each ovary. There were no treatment differences in the number of heifers with a CL on Day −12, the total number of follicles on Day −7, or the total numbers of CL and unovulated follicles on Day 0. Although the total number of recovered ova/embryos were similar among groups (4.2±0.6, 3.6±0.6, and 3.3±0.6 for Control, Inorganic, and Organic heifers, respectively), the number of unfertilized oocytes was greater (P<0.05) in Inorganic (2.3±0.4) than in Organic (0.8±0.4) heifers, whereas Control heifers were intermediate (1.3±0.4). In addition, Control heifers had a greater (P<0.10) number of degenerate embryos (0.9±0.2) than Organic (0.3±0.2) or Inorganic (0.3±0.2) heifers. Organic heifers produced a greater number (P<0.10) of transferable embryos (2.2±0.4) than Inorganic heifers (1.1±0.4), with Control heifers intermediate (2.0±0.4). We conclude that heifer and mineral rotation accounted for the greatest differences in embryo production and quality. However, feeding an Organic mineral tended to increase the production of transferable embryos in purebred Angus heifers.

This paper reviews information pertaining to zinc, copper, chromium, and selenium requirements of athletes. Exercise increases zinc loss from the body, and dietary intake for some athletes, especially females, may be inadequate. Blood copper levels are altered by exercise, but there is no information to suggest that copper ingestion or status is compromised in athletes. Studies have shown that urinary chromium excretion is increased by exercise, but whether this leads to an increased requirement is still unknown. There is concern that athletes may not ingest sufficient quantities of chromium; however, there are inadequate data to confirm this. The limited data that exist show that athletes do not have altered selenium status. There is no conclusive evidence that supplementation with any of these trace minerals will enhance performance. A diet containing foods rich in micronutrients is recommended. However, for those athletes concerned that their diets may not be sufficient, a multivitamin/ mineral supplement containing no more than the RDA may be advised.

In late autumn, 60 gestating Shorthorn cows were assigned at random to one of two feeds (hay or grass silage) and one of three trace mineral supplements (none, sulfates or chelates) to form six groups of 10 animals each. The group of cows fed grass silage exclusively as a maintenance diet and without trace mineral supplementation developed progressively lower blood plasma copper levels compared with those fed only hay. In early summer of the following year, more than half of this group was hypocupremic and the mean blood plasma copper level (< 0.5 μg/ml) was lower than that of the other five groups. This difference was also observed in the level of copper in the milk of the cows before they were turned out onto pasture. In both feeds, there were no differences in consumption of mineral supplements between groups, and the copper intake from the group supplemented with chelates was about 14% of that of the respective group supplemented with sulfates. In terms of plasma iron, hemoglobin level and packed cell volume of whole blood, body weights of the cows and birth weights of their calves, there were no differences when groups with trace mineral supplementation were compared to those without.
