Alfalfa Producers: Do You Really Know How Good Your Alfalfa Is? Forage Analysis: Importance And Interpretation, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Forages make up over 75% of the diet of all cattle and are the basis of cow-calf industry in the midwest. However, a recent survey of over 1000 livestock producers in Missouri revealed that only 5.6 % had ever had their hay tested. They gave several reasons for why they had not tested hay (Table 1). By a large margin, the greatest reason for not testing was that they did not see a need. This fact highlights the purpose of this paper and presentation at the 10th Annual Kentucky Alfalfa Conference. This paper will explain the terms used in …

Growth Stimulants And Feed Additives, Norris J. Stenquist

All Archived Publications

In recent years, the most revolutionary increases in beef cattle weights and feeding efficiencies have resulted from the development and use of growth stimulants, feed additives, and antibiotics. These nonnutritive products not only improve the rate and efficiency of gain but prevent certain diseases as well. Their use has significantly improved beef cattle production efficiency and provided a greater return per dollar invested than any other factor in the livestock industry. Growth stimulants deposit increased protein in the animal without changing protein or energy intake. They are designed to provide a constant slow release of active ingredients into the animal's …

Preweaning Processing Anthelmintic Treatment And Post Weaning Effects Of Sulfamethazine Based Medications On Performance Traits And Oocyst Shedding In Weaned Calves, R.H. Pritchard, J.U. Thomson, M.A. Robbins

South Dakota Beef Report, 1990

Two trials were conducted to evaluate antibiotic therapies for feeder calves originating in western South Dakota. In Trial 1, processing-anthelmintic treatment 28 days before weaning reduced ranch gains and provided no advantage in feedlot gains when calves were reprocessed. Processing included deworming, grubicide treatment, implanting and vaccination. Sulfamethazine medication caused transient improvements in feedlot performance during the feedlot receiving period in both trials. Supertherapeutic treatment with AS 700 offered no advantage in feedlot performance over therapeutic feeding in these calves. Sulfamethazine exposure suppressed coccidia oocyst shedding and appears to be an effective means of controlling coccidiosis and shipping fever complex …

Effects Of Estradiol-Trenbalone Acetate Implant Combinations On Feedlot Performance And Carcass Traits Of Two Steer Types, R.H. Pritchard, D.H. Gee, M.A. Robbins

South Dakota Beef Report, 1990

Hereford x Angus (HA) and predominantly Gelbvieh cross (Gx) steer calves either received no implant (control) or were implanted initially and again at 77 days on feed with a combination of estradiol and trenbalone acetate based implants. Calves were started on feed in December weighing 677 Ib and fed for 146 to 167 days. Fed for a common period of time, implanting steers increased (Pc.05) ADG, dry matter intake, final weight, carcass weight, rib fat thickness and yield grade. Implanting reduced (Pc.01) marbling scores. Gx steers were heavier and grew more rapidly than HA steers. There were no interactions between …

Whole Plant Faba Bean Siage As A Component Of Growing Steer Diets, J.J. Wagner, H. Nantoume, R. Hanson, D.R. Sorenson

South Dakota Beef Report, 1990

Whole plant faba bean silage was compared to corn-alfalfa silage as a roughage source in 30% roughage growing steer diets. When the proportion of faba bean silage was increased from 0 to 10, 20 and 30%, respectively, daily feed intake, average daily gain and feed conversion of the steers were 18.32, 18.38, 18.23, 19.13 Ib per head; 3.66, 3.42, 3.39, 3.57 Ib per head; and 5.01, 5.38, 5.37 and 5.36, respectively. Substitution of faba bean silage for corn-alfalfa silage in a 30% forage diet had no significant (Pc.05) effect on feed intake, weight gain and feed efficiency for growing steers.

Use Of Sunflower Hulls As The Roughage Component Of Finishing Diets For Yearling Steers, R.H. Pritchard, M.A. Robbins

South Dakota Beef Report, 1990

Sunflower hulls were substituted for grass-alfalfa hay as the roughage component of finishing diets for yearling steers. Feed intake was lower when sunflower hulls were fed, resulting in reduced rate of gain and increased feed conversion. When diets were formulated to contain 12% NDF rather than 10% roughage, performance of steers fed either roughage source was similar. Sunflower hulls because of low cost can be used in finishing diets at 5% of dry matter intake without affecting production costs. Feeding higher levels of unprocessed sunflower hulls is discouraged.

Comparative Analysis Of The Proliferative Response Of The Rat Urinary Bladder To Sodium Saccharin By Light And Scanning Electron Microscopy And Autoradiography, Samuel M. Cohen, Maria J. Fisher, Takao Sakata, Martin Cano, Gerald P. Schoenig, Clifford I. Chappel, Emily M. Garland

Scanning Microscopy

Three methods used to detect proliferative changes in the rat urothelium, light microscopy, scanning electron microscopy, and autoradiography, were compared for their sensitivity in detecting changes produced by administration of sodium saccharin. Weanling male F344 rats were fed sodium saccharin as 0, 3, 5, or 7.5% of the diet, and the bladders were evaluated after 4, 7, and 10 wks of feeding. Light microscopic changes and an increase in labeling index were seen at all time points in rats fed 7.5 % sodium saccharin, but not at the lower doses. A slight increase in labeling index was also observed at …

Development Of Sorghum (Sorghum Bicolor (L.) Moench) Endosperm In Varieties Of Varying Hardness, J. M. Shull, A. Chandrashekar, A. W. Kirleis, G. Ejeta

Food Structure

Factors responsible for grain hardness in sorghum are not well understood. Therefore, a study was undertaken to observe differences in the developmental processes of three sorghum varieties which vary in endosperm texture: hard, intermediate, and soft. Grain samples were collected at 5 day intervals beginning at 5 days after half-bloom (DAHB) until physiological maturity (40 DAHB) and prepared for viewing with scanning electron microscopy and transmission electron microscopy.

Comparisons were made between vitreous and floury endosperm portions of each variety and among the three varieties. The major difference between vitreous and floury endosperm was the degree to which the protein …

Coping With Brown Spot And Root Rots Of Lupins, Mark Sweetingham

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

There is increasing concern that brown spot and root diseases may limit the long term viability of lupin cultivation in close rotations in the agricultural areas of Western Australia. Research has found several useful strategies to reduce the impact of brown spot and Pleiochaeta root rot so that losses can be kept to a minimum. Rhizoctonia has proved more difficult to combat. Although less widespread than Pleiochaeta, it has caused severe losses and appears to be increasing in incidence, particularly in the northern wheatbelt. Research has vastly expanded our knowledge of the strains of Rhizoctonia present in our soils and …

Dominance Relationships Of Cycloheximide-Resistant Mutants Of Schizophyllum Commune Fr., Marjorie Meier Eerdmans, Sally A. Amundson, Todd A. Reinhart, Keith K. Klein

Journal of the Minnesota Academy of Science

We have isolated several mutants of Schizophyllum commune Fr. able to grow on media containing cycloheximide in concentrations up to 30 mg/L. Genetic analyses of the resistant phenotypes show them to be due to the action of a single gene located on the first linkage group between the A-mating type factor and a gene for an adenine requirement (ade-ll). We have analyzed the growth and development of dikaryons made homoallelic for either the resistant or sensitive alleles as well as the heteroallelic dikaryon. These dikaryons showed different abilities to fruit when placed on media containing various concentrations of cycloheximide. Homoallelic …

These actions are the result of public issues that have been debated and compromised through the policymaking process. The basic element is the process used to solve a public …

Identification And Characterization Of Cocoa Solids And Milk Proteins In Chocolate Using X-Ray Microanalysis, B. E. Brooker

Food Structure

X-ray microanalysis was used to compare the elemental composition of isolated cocoa solids with milk powder. Whereas mllk powder contained similar high levels of calcium and potassium, cocoa sol ids were rich in potassium but contained very small amounts of calcium.

This difference in elemental composition allowed the two populations of particles to be distinguished in digital X-ray maps of frozen and fractured samples of plain , milk and white chocolates examined by cryo-scanning electron microscopy. The size distributions of particles imaged in this way were determined using standard software and were used to distinguish between two white chocolates whose …

Genotypic And Chemical Influences On Fruit Growth Of Tomato, Henry R. Owen, Louis H. Aung

Faculty Research & Creative Activity

A relationship between ovary size at anthesis and final fruit diameter of 12 tomato (Lycopersicon esculentum Mill.) cultivars with a range of fruit sizes, shapes, and maturation rates was determined. ‘Fireball’, ‘Michigan/Ohio Hybrid’, and ‘New Yorker’ produced nonfasciated, spherical fruits of intermediate maturation rate and showed a significantly higher correlation between ovary diameter at anthesis and final fruit diameter than ‘Small Fry’, ‘Roma VF’, ‘Early Cascade’, ‘Campbell 1327’, or ‘Ponderosa’. A linear regression of final fruit diameter at maturity on ovary diameter at anthesis of the cultivars was highly significant (r2 = 0.92**; ÿ = 22.5X - 0.3). Continuous root …

The Role Of Cell Wall Structure In The Hard-To-Cook Phenomenon In Beans (Phaseolus Vulgaris L.), Ilan Shomer, Nachman Paster, Pinhas Lindner, Rosa Vasiliver

Food Structure

Differences in structure, water uptake and efflux of solubles were found between normal and hard-to-cook beans (Phaseolus vulgaris L.) The staining characteristics of hard beans were different from those of the normal in both non-cooked and cooked tissue, especially in the cell walls. The three zones of the cell wall - the middle lamella, the primary and the secondary walls - were found in both normal and hard-to-cook beans. The primary cell wall of both normal and hard beans was partially degraded upon cooking, as seen by bright fields within the fibrillar pattern. The ultrastructure of the non-cooked secondary cell …

G90-1003 Maximizing Feed Intake For Maximum Milk Production, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide emphasizes the importance of maximizing feed intake for maximum milk production, and management practices which stimulate feeding activity by dairy cattle.

The goal of most dairy producers is to maximize milk production in a cost-effective manner. On the typical dairy farm, feed costs represent nearly 50 percent of the total milk production cost. Economically, it is important to maximize feed intake, improve efficiency of feed use, and lower feeding costs. Many dairy producers fail to realize that there is more involved with properly feeding a dairy cow than looking at a computer printout of a balanced ration. With …

Analysis Of The Fall And Winter Diet Of The Bobcat In Eastern Arkansas, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Food habits of the bobcat (Felis rufus) in eastern Arkansas were examined based on stomach contents of 148 specimens. Rabbits (Sylvilagus floridanus and S. aquaticus) were the primary food source for males, females, and kittens. Rice rats (Oryzomys palustris), nutria (Myocastor coypus), and several species of waterfowl are first reported as food of bobcats in Arkansas. Cotton rats (Sigmodon hispidus) and muskrats (Ondatra zibethica) were more common in bobcat diets in eastern versus western Arkansas. Adult males did not use smaller prey but this food source was common, in kittens; females were intermediate in their use of smaller prey.

Alternatives To And Reduction Of Animal Use In Biomedical Research, Education And Testing, John M. Frazier, Alan M. Goldberg

Experimentation Collection

Biomedical endeavours can be divided into three major categories: research, education, and testing. Within the context of each of these categories, activities involving whole animals have made major contributions and will continue to do so in the future. However, with technological developments in the areas of biotechnology and computers, new methods are already reducing the use of whole animals in certain areas. This article discusses the general tissues of alternatives and then focuses on the development of new approaches to toxicity testing.
