Available in PDF, EPUB and Kindle. Book excerpt: Adequate trace mineral status is important in beef cow/calf and replacement heifer systems because trace minerals play vital roles in reproduction, immunity and growth. Many experiments have investigated the use of a trace mineral injection containing Cu, Mn, Se and Zn (TMI) on growth and immunity of beef cattle. However, very few have investigated TMI use on reproductive performance. Therefore, five experiments, a two year cow/calf experiment, and four replacement heifer experiments were designed to investigate the use of a TMI on reproductive performance of cows and heifers, calf growth and trace mineral status of cows, heifers, and calves. The use of the TMI at pre-calving and pre-breeding did not consistently improve reproductive performance of heifers and cows with good trace mineral statuses that were receiving supplemental trace minerals. There were no differences (P ≥ 0.36) in the AI pregnancy rate [48 and 38% control (CON) vs 44 and 39% TMI, year 1 and year 2, respectively] or overall pregnancy rate (93 and 93 % CON vs 93 and 90% TMI, year 1 and year 2, respectively) of cows receiving a TMI when compared to control cows during the two year trial. In experiment 1 beef heifers (Angus ́Hereford ́Simmental) were bred to fixed time AI, TMI heifers had increased overall pregnancy rates (83 vs 92%, CON vs TMI, respectively; P = 0.02). In experiment 2 beef heifers were AI bred to synchronization response, TMI had no effect (78 vs 83%, CON vs TMI, respectively, P = 0.46). Conception rates to AI and overall pregnancy were not affected by TMI use in two experiments using Black Angus beef heifers being developed in a dry lot fed adequate trace minerals in a total mixed ration. Growth of suckling calves measured as birth weight, average daily gain, actual weaning weight, and 205 d adjusted weight were not influenced by TMI. However, trace mineral status of all groups of cattle were increased with use of TMI. In heifers liver Cu and Se were increased (P

This book was released on 2018 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive efficiency is the major component for an economically efficient cow/calf operation and can be influenced by a number of factors such as breed, age, health and nutrition. Among the components of the diet, trace minerals are hypothesized to have a major impact reproductive efficiency in beef cattle. In order to test this specific hypothesis, a study directly evaluating the success of reproductive performance in cows fed complexed trace minerals versus inorganic trace mineral was designed. In this study, 68 cows where equally divided into treatment (cows fed with complexed trace minerals) and control (cows fed with inorganic trace minerals) groups. The cows started being fed 30 days prior to AI (d -30). Twenty-eight days after AI (d 28), all cows where diagnosed for pregnancy and non-pregnant cows where removed from the experiment. Twenty-four days after pregnancy diagnosis (d 52), pregnant cows where submitted to ovum pick-up (OPU) and a second OPU was performed on d 67. Although pregnancy rates did not differ (P = 0.33) between treatment and control, cows fed with complexed trace minerals had increased oocyte recovery (P = 0.03), in vitro embryo production (P = 0.06) and more efficient in vitro embryo production (P = 0.06). In summary, the results from this experiment demonstrated that supplementation of beef cows with a complexed source of trace minerals improves reproductive efficiency when compared to cows fed inorganic source of trace minerals.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective was to evaluate the effects of pre- and post-partum bolus injections of a trace mineral solution on beef cow reproductive performance, body weight (BW) change, and body condition score (BCS) change and on performance of suckling calves. Mature beef cows (n = 460; initial BW = 497± 89 kg, initial BCS = 5.4± 0.74) were stratified by BCS, parity, and predicted calving date and assigned randomly to 1 of 2 treatments: 1) subcutaneous trace mineral (TM) injection containing 15 mg/mL Cu, 5 mg/mL Se, 10 mg/mL Mn, and 60 mg/mL Zn or 2) subcutaneous injection of physiological saline (SA). Injections were administered to cows (1 mL / 90 kg BW) 105 days before the first projected calving date and again 30 days before fixed-time AI. Calves received the same treatment as their dams and were injected (1 mL / 45 kg BW) at birth and again at 71± 21 days of age. Cows grazed native pastures for the duration of the study; trace mineral supplements and white salt were available to all cattle ad libitum before and during the study. Ovulation was synchronized using a 5-d CO-Synch + CIDR protocol and cows were inseminated 60 to 64 hours after CIDR removal. Cows were exposed to fertile bulls for natural-service breeding 10 days after AI for 35 to 50 days. Conception to AI and final pregnancy rate were assessed 36 days after AI with ultrasound and 120 days after AI via rectal palpation. Change in BW and BCS from initiation of the study to calving and from AI to weaning did not differ (P [equal to or greater than] 0.15) between TM and SA cows. Conversely, TM cows had greater (P = 0.04) BCS increase than SA cows between calving and AI. Calf BW at birth, ADG, and age-adjusted weaning BW did not differ (P [equal to or greater than] 0.36) between treatments. Proportion of cows with estrus cycles 17 and 8 days before ovulation synchronization was similar (P [equal to or greater than] 0.51) between treatments. Conception to AI was greater (P = 0.05) for cows receiving TM (60.2%) than for cows receiving SA (51.2%); however, overall pregnancy did not differ (P = 0.24) between treatments and averaged 92%. Under the conditions of our study, pre- and post-partum TM injections improved conception to fixed-time AI by beef cows.

This book was released on 2014 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calves treated for bovine respiratory disease (BRD) were randomly assigned to 1 of 4 experimental ancillary therapy (ANC) groups: flunixin meglumine (NSAID), viral vaccination (VACC), vitamin C (VITC), or no ANC (NOAC). When contrasted with the average of the 3 ANCs calves receiving NOAC tended to have heavier BW on d 56, greater ADG and DMI from first BRD treatment through d 28, greater DMI from d 28 through d 56, and had greater DMI from first BRD treatment through d 56 with mortalities and removals excluded (P = 0.06, P = 0.10, P = 0.08, P = 0.06, and P = 0.05 respectively). Morbidity and mortality attributed to BRD were 66.5% and 13.2% respectively. Calves were then grouped by ANC treatment and the number of times treated for BRD (BRDX) and allocated to finishing pens. The BRDX experimental groups included: never treated for BRD (0X), treated 1 time (1X), 2 times (2X), or 3 or 4 times (3/4X). No ANC group differences existed for any of variables analyzed (P >̳ 0.26). With increasing BRDX, days on feed and lung consolidation scores increased linearly (P ≤ 0.01), while hot carcass weight, dressing percentage, rib eye area, and the percentage of USDA Prime and Choice carcasses decreased linearly (P

Ryan and published by . This book was released on 2014 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of supplemental zinc (360 mg/d), copper (125 mg/d), and manganese (200 mg/d) from inorganic, organic, or hydroxy sources fed daily over a 42 to 45-d backgrounding phase. After removal of chronic and dead calves from the data set, trace mineral source had no effect on final or intermediate weights (P > 0.55) or average daily gain (P = 0.51). For all calves, dietary treatments had no effect on any morbidity measurements (P ≥ 0.53). Overall, trace mineral source had no effect on total weight gain, average daily gain, or morbidity during the receiving phase in shipping stressed cattle. A second experiment was conducted to study the effect of trace mineral source on trace mineral status, superoxide dismutase activity, and performance in beef heifers fed diets high in sulfur. Crossbreed heifers were stratified into 3 treatments consisting of 1) no supplemental trace minerals; 2) supplemental copper (55 mg/d), zinc (165 mg/d), and manganese (110 mg/d) from sulfate sources; or 3) supplemental zinc, copper, and manganese at isolevels to treatment 2 from hydroxy sources fed daily over a 55-d trial. Final and intermediate weights (P = 0.73), average daily gain (P = 0.70), and plasma copper and zinc concentrations (P ≥ 0.37) were not affected by treatment. Liver copper concentrations on d 55 were greater for the sulfate treatment (P > 0.004) compared to control and hydroxy treatments, however, liver zinc concentrations were not affected (P > 0.29). Treatment had no effect on ( P ≥ 0.36) on total- or manganese-superoxide dismutase activity, however, a day effect (P ≥ 0.002) was observed. Overall, trace mineral source had no effect on growth performance, plasma mineral concentration, liver zinc concentrations, or superoxide dismutase activity. However, liver copper concentrations on d 55 were affected by trace mineral source.

Download or read book The Role of Trace Minerals in Beef Cattle Fertility written by Cole R. Ratzburg and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important economic factor influenced by trace mineral deficiencies is impaired reproductive performance in both the male and female. Copper (Cu), Zinc (Zn), and Manganese (Mn) have been shown to improve fertility in male and female beef cattle due to their roles in vitamin synthesis, hormone production, enzyme activity, collagen formation, tissue synthesis, oxygen transport, energy production, and other physiological processes related to growth, reproduction and health. A new form of trace minerals called hydroxy minerals, which is a hydrolyzed inorganic metal complex, has been shown to have a greater bioavailability than sulfate minerals and similar bioavailability compared to the organic trace minerals. The idea that hydroxy trace minerals could be more available to beef cattle led us to hypothesize that use of hydroxy forms of Cu, Zn, and Mn could improve fertility in male and female beef cattle that are transitioning into the pubertal phase. The objectives of the two studies were to determine if the use of hydroxy trace minerals could improve fertility parameters related to both the male and female beef cow. Peripubertal bulls were supplemented with hydroxy forms of Cu or Zn or Cu and Zn or no Cu and Zn in an 83-day mineral trial to determine if there were differences in liver, blood plasma, and semen mineral concentrations and subsequently breeding soundness exam (BSE) parameters, sperm morphology, and flow cytometer analysis. Results showed the use of Cu and Zn had benefits for fertility as there was improvements in flow cytometer parameters and sperm morphology. Heifers were supplemented with sulfate and hydroxy forms of Cu, Zn, and Mn to determine if the different forms of trace minerals could affect feed intake parameters such as average daily gain, dry matter intake, residual feed intake, and feed to gain ratio and the fertility parameters: percent cycling and percent conception. Results indicated that there were no differences in feed intake parameters between treatments, but there was a positive benefit observed with the hydroxy trace minerals on conception percentage.
