Effect Of Dietary Urea In Gestating Beef Cows: Circulating Metabolites, Morphometrics, And Mammary Secretions, Ligia D. Prezotto, Jennifer F. Thorson

Department of Animal Science: Faculty Publications

Prolific use of supplementation strategies, including the utilization of urea, are practiced in beef cattle production systems. Unfortunately, the influence of urea supplementation on metabolics, adipose tissue mobilization, and mammary secretions is limited in beef cows. Therefore, the objectives of this experiment were to assess the influence of urea supplementation on metabolic profiles, morphometrics, and mammary secretions. Pregnant, multiparous beef cows were fed individually and assigned to treatment (n = 4/treatment) as Control or Urea Supplementation. Blood samples and body weight were collected every 28 d throughout gestation. Backfat thickness was measured via ultrasonography on days 28 and 280 of …

Roman L. Hruska U.S. Meat Animal Research Center: Reports

This review resulted from an international workshop and presents a consensus view of critical advances over the past decade in our understanding of follicle function in ruminants. The major concepts covered include: (1) the value of major genes; (2) the dynamics of fetal ovarian development and its sensitivity to nutritional and environmental influences; (3) the concept of an ovarian follicle reserve, aligned with the rise of anti-Müllerian hormone as a controller of ovarian processes; (4) renewed recognition of the diverse and important roles of theca cells; (5) the importance of follicular fluid as a microenvironment that determines oocyte quality; (6) …

Characterization Of Growth Patterns And Meat Quality Characteristics Of Four Commercial Broiler Strains In Small Bird And Large Bird Programs In The United States, Clay Johnny Maynard

Graduate Theses and Dissertations

Through current trends in animal protein consumption, the United States poultry industry has seen a drastic rise in production and popularity. Over the last few decades, poultry meat has surpassed both beef and pork production to become the most widely consumed animal protein. This rise may be accredited to an increased transition to more health-conscious consumers. As more consumers purchase poultry as a lean source of protein, the need for a superior quality product is of great interest to poultry integrators.

Relationships between commercial broiler lines have been well documented in previous years, but constant and intensive genetic selection in …

Nutritional Requirements Of Different Classes Of Meat Goats, Nar Gurung

Professional Agricultural Workers Journal

Abstract

Feeds provide nutrients to animals. Feeds can be grains, crop by-products or forages. Forages can form the basis of feeds for goats in the southeastern US because year-round forage production is possible. Since goats are classified as browsers, the forage program should consist of browse and pasture. Managing browse species as feed resources is challenging, and there is limited information relative to managing browse species. Hay is the main forage feed for goats in the region and average quality hay can meet nutrient requirements for maintenance. However, nutrient requirements for late-pregnancy, lactation, and growing goats cannot be met with …

This course provides students with a farmer’s perspective on the sustainable management of cows, sheep and goats on a small farm. The course provides students with a clear understanding of how to think through the planning and management of cows, sheep and goats for meat production. All aspects from purchasing and nutrition to marketing and finances will be addressed. This course also brings awareness to the U.S. meat industry and supports students in becoming educated consumers and producers. Students will walk away with a rudimentary plan on how to incorporate ruminants into their small farm plan.

Research Note Prediction Model For Manure Zinc Excretion In Laying Hens, Kelli M. Martin, N. Vargas-Jurado, S. E. Purdum

Department of Animal Science: Faculty Publications

The objective of this research trial was to compare 2 sources of zinc and different levels of supplementation on manure zinc excretion in laying hens. Bovan White Leghorn hens were used in this study and fed one of 6 dietary treatments. Treatments were in a 2 × 3 factorial arrangement with 2 sources of zinc (zinc sulfate or Availa R < Zn) and 3 levels (40, 80, or 120 ppm) and were randomly assigned to 48 cages with 5 hens/cage and 8 replicates/treatment. Hens were housed in a tiered manure-belt housing system providing 627.1 cm2/hen and were given access to 110 g/hen/d of feed. Manure samples were collected, and manure zinc content was calculated at 10- week intervals. Data were analyzed using the Glimmix procedure in SAS. There was a significant overall effect of source (P < 0.0001) for zinc content, such that hens fed zinc sulfate had lower amounts of zinc excretion. There was also a significant level effect (P < 0.0001) in which hens fed 120 ppm zinc excreted the greatest amount of zinc. A significant source by level interaction was observed (P < 0.0001) for both the overall and individual analyses, such that 120 ppm Availa R < Zn showed the highest zinc excretion, and both 40 ppm zinc sulfate and Availa R < Zn showed the lowest zinc excretion. Based on these results, a prediction equation was written for an estimated amount of zinc excretion based on the amount of zinc provided in the diet.

The experts were selected by a non-probability sampling of researchers on veterinary and animal sciences. In addition, five farmers and eight technical consultants were also selected. The questionnaire was applied during a face-to-face meeting. The risk of each practice was assessed according to four factors, namely, cost, technical knowledge, operational complexity, …

Growing Yeast For Livestock, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Over 500,000 tons of organic materials such as food scraps are disposed of each year in Wisconsin. A large percentage of this material could be composted or turned into useful products.5 The purpose of this article is to educate farmers and organizations on how to turn food waste into a high value food source for livestock. Yeast can be grown at any time of the year without the large inputs of agricultural chemicals and machinery that is common with other feed production methods. A yeast growing facility can be scalable to any size the producer wants such as a small …

The Effect Of Copper And Zinc Source On Pre-Weaning Performance Of Cows, Health And Performance Of Suckling Calves, And Post-Weaning Feedlot Performance, Carcass Composition, And Meat Quality Of Calves, Jesse Fulton

Electronic Theses and Dissertations

During gestation an elevated level of nutrient intake is required by the cow in order to meet the requirements of the maturing fetus and if these requirements are not met, changes in fetal development can occur. However, little is understood about the effects of gestational manipulation of specific nutrients, such as minerals, on progeny growth, performance and carcass traits. Previous research supports the hypothesis that minerals provided in an organic form should be more soluble and readily available to the body for absorption. Therefore the objectives of this study were to determine if source of gestational and post-natal Cu and …

Department of Animal Science: Faculty Publications

Transcriptome dynamics in the longissimus muscle (LM) of young Angus cattle were evaluated at 0, 60, 120, and 220 days from early-weaning. Bioinformatic analysis was performed using the dynamic impact approach (DIA) by means of Kyoto Encyclopedia of Genes and Genomes (KEGG) and Database for Annotation, Visualization and Integrated Discovery (DAVID) databases. Between 0 to 120 days (growing phase) most of the highly-impacted pathways (eg, ascorbate and aldarate metabolism, drug metabolism, cytochrome P450 and Retinol metabolism) were inhibited. The phase between 120 to 220 days (finishing phase) was characterized by the most striking differences with 3,784 differentially expressed genes (DEGs). …

Effects Of Level Of Energy Supplement In Early Winter And Level Protein After Calving On Beef Cows Grazing Native Range, R.J. Pruitt

South Dakota Beef Report, 1986

Simmental-Angus crossbred cows grazing native range near Cottonwood, SD, were fed two precalving levels of energy supplement and two postcalving levels of protein supplement. Cow weight change and reproductive performance were similar for all treatments. Although calves from cows supplemented with higher levels of energy gained faster from birth to early May, gains to weaning were similar for all treatments.
