Mineral Nutrition In Broilers: Where Are We At?, Rick J. Kleyn, Mariana Ciacciariello Aug 2021

Mineral Nutrition In Broilers: Where Are We At?, Rick J. Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Mineral nutrition remains an essential consideration for broiler nutritionists. The complex interactions between different minerals sources, other ingredients, and the broiler itself, coupled with their relatively low costs, have led to the current status of elevated levels of minerals in broiler diets. New perspectives on sustainability have brought about a rethink of the way we formulate practical diets. There are considerable opportunities for reducing macro minerals such as calcium and phosphorus, particularly for older birds. Our understanding of attaining an ideal dietary cation-anion balance is confused by the lack of clarity in measuring the balance and the bird’s ability ...

The objective of this study was to evaluate the effect of timing of electrical stimulation on free calcium concentration, calpain-2 activity, Warner-Bratzler shear force (WBSF), and consumer sensory analysis. Twenty-three beef steers were harvested and stimulated (S) using extra-low voltage or not stimulated (NS), at exsanguination and/or 1 h postmortem, resulting in 4 different stimulation treatments: NS-NS, NS-S, S-NS, or S-S. Samples were removed from the longissimus lumborum (LL) and semimembranosus (SM) for free calcium and calpain-2 analysis on days 1, 4, and 14 postmortem. WBSF and sensory analysis steaks were removed on day 4 and frozen (4 d ...


Effect Of Calcium Supplement On Eyesight Of Western Tiger Salamanders, Abigail Horner, Dennis Ferraro Apr 2020

Effect Of Calcium Supplement On Eyesight Of Western Tiger Salamanders, Abigail Horner, Dennis Ferraro

UCARE Research Products

There has been some discussion in herpetoculture about adding calcium supplements to the diets of salamanders. Adding calcium supplements to a salamander’s diet has been indicated to contribute to blindness. Calcium supplements are usually given to reptiles and amphibians to prevent dietary deficiencies, particularly metabolic bone disease. The link between lack of calcium and metabolic bone disease is well established in reptiles, but is lacking significant research with regards to amphibians. Within the eye of a salamander, there are calcium channels that mediate photosynthetic rods in the absence of light. With a calcium rich diet, it is believed that ...

Consumption of a Western type diet is a known risk factor for colorectal cancer. Our group previously developed the total Western diet (TWD) for rodents with energy and nutrient profiles that emulate a typical Western diet. In this study, we tested the hypothesis that consumption of the TWD would enhance colitis, delay recovery from gut injury and promote colon tumorigenesis. In multiple experiments using the azoxymethane + dextran sodium sulfate or ApcMin/+ mouse models of colitis-associated colorectal carcinogenesis (CAC), we determined that mice fed TWD experienced more severe and more prolonged colitis compared to their counterparts fed the standard AIN93G ...

Evaluating Phosphorus Release By Phytase In Diets Fed To Growing Pigs That Are Not Deficient In Phosphorus, Kristin M. Olsen, Stacie A. Gould, Carrie L. Walk, Nick V. L. Serão, Stephanie L. Hansen, John F. Patience

Animal Science Publications

Microbial phytase is widely used to enhance digestibility of phytate-P. By tradition, diets with P content well below requirement are used to quantify phytate-P release by phytase, but P-adequate diets may be more physiologically relevant. The objective of this study was to investigate the effects of phytase on P digestion and metabolism and develop a P release curve for phytase in Padequate diets (above requirement according to NRC, 2012), and to compare these effects in a Pdeficient diet. Three replicates of 24 barrows each (BW = 23.0 ± 1.8 kg) were randomly assigned to 1 of 8 dietary treatments, housed ...


Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell Aug 2018

Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell

Master's Theses

Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia. A strategy to correct this nutrient imbalance involves supplementing the insect diet with high concentrations of targeted nutrients – a term referred to as gut-loading. Current industry guidelines recommend feeding a supplemented diet for 48 ...

Kansas Agricultural Experiment Station Research Reports

While numerous research articles have been published on how to collect a representative sample, and analytical or laboratory-to-laboratory variation, we are unaware of any studies to examine exactly how many samples to collect from feeders, or whether they should be pooled or not to minimize analytical variation. Therefore, this study was designed to evaluate different sampling procedures and the number of samples to collect, and achieve an accurate assessment of nutrient fortification in swine diets.

Diet samples were collected from a study evaluating the effects of increasing Cu on growth performance of finishing pigs. Treatments were arranged in a split-plot ...


The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Wilkerson Dec 2016

The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Wilkerson

Theses and Dissertations in Animal Science

Distillers grains (DG) contribute to cattle sarcoplasmic reticulum (SR) membrane instability by increasing poly-unsaturated fatty acid (PUFA) content in the SR membrane, possibly resulting in early postmortem calcium (Ca) leakage and improved tenderness. Mitochondria are relatively easy to isolate intact and provide the opportunity to study Ca in an SR model. The objective of this research was to determine the influence of diet and oxidation on Ca release from mitochondria. Cattle (n=48) were fed a corn-based finishing diet with or without deoiled, dried DG (50% DM basis). Steaks from each strip loin were aged for 2, 8, 14, and ...


Evaluation Of Negative Energy And Mineral Balance In Periparturient Holstein-Friesian Cattle, Ameer Ahmed Abdelhameed Apr 2016

Evaluation Of Negative Energy And Mineral Balance In Periparturient Holstein-Friesian Cattle, Ameer Ahmed Abdelhameed

Open Access Dissertations

Most cows experience a state of negative energy and mineral balance during the periparturient period. This imbalance is a major problem in the dairy industry and it is more frequently seen in multiparous cattle due to their high milk production. A large amount of fat and protein is mobilized in order to address the energy deficit during the periparturient period. The ability to accurately monitor energetics and electrolytes status using accurate, rapid, and low cost point-of-care instruments will assist in optimizing animal health and productivity.

This dissertation contains three studies that evaluated point-of-care instruments for measuring blood and plasma glucose ...


Longevity Of Mineral Supplements Within The Soil And Associated Use By White-Tailed Deer, Brian C. Peterson, Keith D. Koupal, Andrew K. Schissel, Cody M. Siegel Dec 2015

Longevity Of Mineral Supplements Within The Soil And Associated Use By White-Tailed Deer, Brian C. Peterson, Keith D. Koupal, Andrew K. Schissel, Cody M. Siegel

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Humans have baited wildlife such as white-tailed deer (Odocoileus virginianus) for generations with the primary purpose of increasing hunting harvest success. Baiting regulation changes are often considered by state management agencies as they pertain to hunting opportunity, fair chase, and disease risk. Cervids require a variety of minerals to supplement biological processes, especially sodium (Na), calcium (Ca), and phosphorus (P). We developed artificial mineral supplement sites set in front of trail cameras to monitor deer use. Pooled soil samples were collected at mineral sites and compared to the surrounding area to determine the longevity of elevated minerals levels within the ...


Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson Jul 2015

Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson

Graduate Theses and Dissertations

Broiler breeder hens are subject to the dual expectation to not only maintain a high production of eggs for an extended time period, but to produce eggs which can support the life of chicks which will be used for either meat production or as parent stock. Egg fertility and hatchability are heavily influenced by the thickness of the egg shell, the mineral calcium carbonate shell of the egg necessary for protecting the embryo growing inside. Many factors affect egg shell quality including age of the hen, diet, environmental conditions, genetic strain, stress, disease, and nutrition. Laying hens will mobilize calcium ...


Store-Operated Calcium Entry And Its Function During Fertilization In Porcine Eggs, Chunmin Wang Oct 2013

Store-Operated Calcium Entry And Its Function During Fertilization In Porcine Eggs, Chunmin Wang

Open Access Dissertations

In a variety of mammalian cells, the depletion of intracellular Ca2+ stores leads to Ca2+ influx across the plasma membrane though a process known as store-operated Ca2+ entry. It not only plays a critical role in the replenishment of the Ca2+ stores but it is also responsible for the maintenance of long-lasting high intracellular Ca2+ levels and sustaining repetitive Ca2+ oscillations. During fertilization a Ca2+ signal, which can take the form of a single or multiple Ca2+ elevations (depending on the species) is the universal trigger for the egg-to-embryo transition. For sustaining ...


Fertilization Characteristics Of Spermatozoa Collected From Bulls Grazing Tall Fescue Pastures, Jessica Pegan Harris Aug 2011

Fertilization Characteristics Of Spermatozoa Collected From Bulls Grazing Tall Fescue Pastures, Jessica Pegan Harris

Masters Theses

Consumption of toxic endophyte-infected (E+) tall fescue pastures is known to have a negative impact on bull reproductive performance. Since decreased cleavage rates of embryos fertilized with spermatozoa from bulls grazing E+ tall fescue pastures have been observed in several studies using differing sets of bulls, technicians, pastures, and other methods of inducing tall fescue toxicosis (ergotamine tartrate), it is hypothesized that spermatozoa function from bulls grazing E+ is impaired in ways undetectable by gross semen examination.

During a three-month grazing study, 6 Angus bulls were utilized to determine the effects of grazing E+ tall fescue pastures on growth performance ...


The Interactive Effects Of Phosporus And Calcium On Phosphorus Requirement, Utilization, And Phytase Efficacy In Poultry, Syrena Powell Jan 2009

Calcium Dynamics Affecting Egg Production, Skeletal Integrity, And Egg Coloration In Ring-Necked Pheasants (Phasianus Colchicus), Landon R. Jones Dec 2007

Calcium Dynamics Affecting Egg Production, Skeletal Integrity, And Egg Coloration In Ring-Necked Pheasants (Phasianus Colchicus), Landon R. Jones

Theses and Dissertations

These 4 chapters represent manuscripts formatted for submission to journals based on an experiment conducted on Ring-necked Pheasants (Phasianus colchicus). Calcium limits the distribution of this species, which produces 7-15 eggs per clutch. They may renest up to 5 times per breeding season on a diet low in calcium. The first chapter examines egg production in laying hens on 7 different diets from 0.19-4.47% calcium in the absence of calcium loading. Calcium-loaded pheasants store calcium in medullary bone before an experiment and can draw on this surplus during egg production, possibly skewing experimental results. We measured egg production ...

Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare Jan 1989

Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare

Journal of the Department of Agriculture, Western Australia, Series 4

Sheep fed cereal grains as an energy source over summer usually need added calcium because cereal grains are generally low in calcium (for example, 0.03 per cent calcium compared to 0.26 per cent phosphorus), and there may not be a natural source such as clover, weeds, leafy stubble or edible bush in the paddock.

The safestt and most effective calcium supplement is finely ground limestone added to the feed, but some farmers have used other sources of calcium such as gypsum and superphosphate in this manner.


Prevention Of Silica Urinary Calculi In A Laboratory Animal Model, Royce J. Emerick, Carl J. Schreier, Donghao Lu Jan 1986

Prevention Of Silica Urinary Calculi In A Laboratory Animal Model, Royce J. Emerick, Carl J. Schreier, Donghao Lu

South Dakota Beef Report, 1986

An animal model utilizing Sprague-Dawley rats fed a diet containing 2% of tetraethylorthosilicate (TES) has been used to study urinary conditions and dietary factors preventing silica urinary calculi . The basal TES diet produced approximately a 50% incidence of silica urinary calculi. Supplemental dietary phosphorus and the urinary acidifying agent ammonium chloride greatly reduced the urinary calculi incidence, while supplemental dietary calcium and urine alkalinization with sodium bicarbonate increased the incidence. The protection from silica urinary calculi provided by sodium or ammonium phosphate compounds was found to be independent of their urinary acidifying effects, and the effects of phosphates and ammonium ...
