INSTRUCTIONS FOR AUTHORS OF JOURNAL OF DAIRY SCIENCE!

The American Dairy Science Association in­vites scientists from all countries to submitpapers for the Journal. Authors need not bemembers of ADSA.

These instructions detail the fonn and stylerequired by JOU17UJ1 ofDairy Science for paperssubmitted for publication in the Journal. Papersthat do not follow the style and fonn of theJournal may be rejected without review. Referto these instructions when preparing the manu­script and when checking galley proofs.

Data including graphs, figures, tables, andillustrations must not have appeared in printexcept as abstracts, local or regional field dayreports, extension letters, or nonpeer-reviewedproceedings of conferences. Articles submittedto Journal of Dairy Science should not besubmitted for publication to popular magazines,company advertisements, or organizationalproceedings until the author has received notifi­cation of acceptance of the manuscript. Beforemanuscripts are submitted, authors should havethem read critically by others to facilitate re­view, and the senior author should haveauthorization to publish. All coauthors shouldbe contacted and approve the manuscript beforeits submission to the Journal.

Authors should read the statement on publi­cation ethics, J. Dairy Sci. 68:3124.

Papers accepted become the copyright of thejournal and may be reprinted only by the pub­lisher. The Editor may authorize reproductionof graphs, tables, and illustrations for booksand periodicals. Requests to reproduce materialpublished in Journal of Dairy Science must bemade in writing and addressed to the Editor.

A reviewed paper returned to authors forrevision must be returned to the editor within 3months; symposium papers must be returned tothe editor within 3 months. If not, the paperwill be treated as a new submission. Underunusual circumstances, editors may extend the

revision deadline beyond 3 months.The page charge per printed page is $70 for

members (if one of the authors is a member)and $130 for nonmembers for papers publishedin Journal of Dairy Science. A schedule ofprices and form to order reprints accompanyauthor proof, but authors are not required toorder reprints. Symposia received before Sep­tember 1, invited papers, and invited reviewpapers are not subject to page charges.

For cases in which only the authors' per­sonal funds are available for payment and suchpayment would be a hardship, authors mayrequest, prior to publication, a page chargewaiver from the Executive Director, 309 W.Clark St., Champaign, II.. 61820. Authors whoapply for page charge waivers may not orderreprints. Page charge waivers are limited to oneper institution per year.

Submission of Electronic Manuscripts

Journal of Dairy Science does not pennitsubmission of new manuscripts on floppy disk.However, authors interested in submitting thefinal version of the accepted manuscript on diskshould request instructions from the technicaleditor at the time of manuscript submission oracceptance. At present, only the text ofmanuscripts may be sent on disk; tables,figures, and mathematics must be sent in thetraditional manner.

Because technological advances are occur­ring rapidly in this area, requirements for prep­aration of manuscripts on floppy disk are sub­ject to change and authors should verify thatthe instructions they have are the most currentset.

Measures and MathemaUcs

Measures must be in the metric system;however, US equivalents may be used in theOur Industry Today section with pennission ofthe editors.

Authors of papers containing mathematicsshould clearly indicate what material, if any, isto be typeset in boldface type. If boldface fontsare not available for manuscript preparation,boldface should be indicated using a yellowhighlighter.

Headings

Three classes of headings are used withinthe text of the manuscript.

Major headings are centered, all capitals,boldface, and consist of ABSTRACf, INTRO­DUCTION, MATERIALS AND METHODS,RESULTS, DISCUSSION (or RESULTS ANDDISCUSSION), CONCLUSIONS, AC­KNOWLEDGMENTS, REFERENCES, and,optionally, APPENDIX.

First subheadings begin at the left margin,the first letter of all important words is capital­ized, and the headings are boldface. If you donot have boldface capability, leave space forthe copy editors to indicate boldface. Do nothandwrite a boldface symbol or use an under­line.

Second subheadings begin the first line of aparagraph. They are indented, underlined oritalicized, and followed by a period. The first

10urnal of Dairy Science Vol. 74. No.1. 1991

letter of all important words should be capital­ized.

TITLE PAGE

Across the top of the title page (first page).indicate a running head (abbreviated title) ofless than 40 letters. The running head is cen­tered and typed in all capital letters. The titleshould be boldface, limited to 100 letters, andcontain no abbreviations. The first letter of eachword is capitalized except for articles andprepositions of under five letters. The titleshould contain the words or phrases used· forindexing the article.

Names of authors should be under the titlewith their affiliations following on the nextline. Names of authors are to be typed allcapitals (space between initials). Institutionsand addresses are listed in upper and lower caseletters. State or provincial postal code abbrevia­tion is not included between city and zip codeif the state or province is previously mentionedin the address (see example).

Footnotes to the title appear on the bottomof the first page. Supplementary address infor­mation is given in footnotes to the first page.Footnotes referring from authors to displayedaddresses are not allowed. Acceptable format isshown.

ABSTRACT

The abstract should review important objec­tives, materials, results, conclusions, and appli­cations as concisely as possible. The abstractdisseminates scientific information through ab­stracting journals and through convenience forreaders. Use the following guidelines in prepar­ing the abstract.

ASSOCIATION AFFAIRS 343

Limit to 200 words.Open with objectives unless they are clear in

the body of the paper. Do not repeat the title.Make intelligible without reference to com­

plete paper. Use complete sentences and stan­dard terms. Use no abbreviations except thefollowing: units of measure with digits, abbrev­iations defined on the inside front cover of thelournal, and chemical elements and commoncombinations of chemical elements.

Minimize amount of data in the abstract.Exclude statements of statistical probability.

Exclude references to other work.

KEY WORDS

List two to four key words for subject index­ing the article. In most instances, these keywords should be taken from the title. Limitselection to four words or phrases, in lowercase, enclosed in parentheses, and separated bycommas.

ABBREVIATION KEY

Each manuscript should include an alphabet­ical key to all author-defined abbreviationsused in the body of the paper. The key shouldnot contain the abbreviations given on the in­side cover of the Journal, symbols for chemicalelements, or abbreviations for standard units ofmeasure. The key should not contain itemsused only in an equation, table, or figure.

EXAMPLE: ~ = estradiol,

Fe-WP = Fe-whey protein,

GCGF = ground com gluten feed,

mtDNA = mitochrondrial DNA,

rbJFN = recombinant bovine interferon.

BODY OF THE PAPER

The body of the paper should contain anintroduction to the problem (questions, objec­tives, reasons for research along with relatedliterature); materials, methods, experimental de­sign, and procedures; results, discussion, con­clusions, and applications.

Major headings are ABSTRACf, INTRO­DUCTION, MATERIALS AND MElliODS,RESULTS, DISCUSSION (or RESULTS ANDDISCUSSION), CONCLUSIONS, AC­KNOWLEDGMENTS, REFERENCES, and,optionally, APPENDIX.

Statistical Analyses

Analyses must include appropriate statisticaltreatment of variation.

Sensory Data

Sensory data should comply with the "State­ment of Policy in the Report of the Committeeon Sensory Data to the.Journal ManagementCommittee of the American Dairy Science As­sociation, 1986," J. Dairy Sci. 69:298. Mentionof an enzyme should include EC number.

computer Software

Computer software should confonn to the"Report of ADSA Subcommittee on Standardsfor Publications with Reference to ComputerSoftware," J. Dairy Sci. 70:209.

Nomenclature for Microorganisms

All microorganisms must be named by ge­nus and species. Current names appear in Ber­gey's Manual of Systemic Bacteriology, Vol­ume 1 (1984) edited by N. R Kreig and J. G.Holt; Volume 2 (1986) edited by P.RA.Sheath, N. S. Mair, M. E. Sharpe, and J. G.Holt; Volume 3 (1989) edited by 1. T. Staley,M. P. Bryant, N. Pfeenning, and J. G. Holt; andVolume 4 (1989) edited by S. T. Williams. ME. Sharpe, and J. G. Holt; The Yeasts: A Taxo­nomic Study, 3rd edition (1984) edited byN.J.W. Kreger-van Rij; Ainsworth and Bisby'sDictionary of the Fungi, Including the Lichens,7th edition (1983) edited by D. L. Hawksworth,B. C. Sutton, and G. C. Ainsworth; and Classi­fication and Nomenclature of Viruses preparedby the International Committee on Taxonomyof Viruses, edited by RE.F. Matthews andpublished in Intervirology 17:23-199 (1982).These documents should be used to determinethe correct names of the microorganisms. Also,names of bacteria that have been validated andpublished in the International Journal of Sys­temic Bacteriology since Bergey's Manual waspublished should be used.

The name of the genus must appear the firsttime that the microorganism is cited in theabstract, in the body of the paper, and in eachtable and figure legend. Thereafter, the genuscan be abbreviated by its first initial unless itwill be confused with other microorganisms

344 JOURNAL OF DAIRY SCIENCE

cited in the paper. The names of all microorg­anisms should be underlined or typed in italicsin the manuscript. Specific strain designationsand numbers should be used where appropriate.

For microorganisms that are genetic variantsof a parent strain, the genotypic and phenotypicproperties should be cited according to the pro­cedures described by Demerec et at (1966) inGenetics 54:61-76. Phenotypes should be iden­tified by three letters; the first is capitalized.Genotypes should be identified by three lowercase italic letters. Superscript plus (+) signs areused to refer to a wild-type. The serial isolationnumber is placed after the locus symbol formutations. The delta symbol is used to indicatedeletions. Nomenclature for bacterial plasmidsshould be cited according to Novick et al.(1976) in Bacteriol. Rev. 40:168-189.

AbbrevlaUons

Abbreviations are not allowed in the title.Do not begin a sentence with an abbreviation.

Define first use of abbreviations in text andin each table and figure.

List abbreviations and their definitions in theabbreviation key. Exceptions are those wordsdermed inside the front cover of the Journal,units of measure with digits, and chemical sym­bols.

Style and Format

Mention of any conunercial product shouldinclude manufacturer, city, and state (and coun­try, if outside the US). This information shouldbe included parenthetically in the text.

Note that "and/or" is not permitted; choosethe more appropriate meaning or use "x or y orboth."

. Use the slant line only when it means "per"~th nU~bered units of measure or "divide by"m equations. Use only one slant line in a givenexpression: e.g., 2.3 kg/d per cow. The slantline may not be used to indicate ratios, mix­tures, or substitute for the words "and" or "or".

Footnote numbers should follow punctuation(e.g., Jones,l or " .end of sentence.2).

Use "to" instead of a hypen to indicaterange.

Do not use italics for foreign words andphrases (e.g., in vivo, ad libitum, etc.)

Indicate probability with a capital italic P,e.g., P < .05.

Journal of Dairy Science Vol. 74, No. I, 1991

Insert spaces around all signs of operations(equal signs, minuses, pluses, times signs, andgreater than or less than signs) when thesesigns occur between two items.

Do not use zeros left of decimal in text,tables, or figures.

Use the final comma for items in a series.Restrict use of "while" and "since" to mean­

ings related to time. Appropriate substitutesinclude "and", "but", or "whereas" for "while";and "because" or "although" for "since".

REFERENCES

List a minimum of pertinent references(generally 30 or fewer).

References are listed alphabetically by au­thor. Secondarily, use chronological order forpapers with identical authorship.

Use the English system of alphabetizing,e.g., deVries, van Waller (not Vries, de orWaller, van).

Number entries consecutively and cite in thetext by number in parentheses (space betweenmultiple reference numbers, e.g., 1,3,5,6). Donot use periods after entry numbers.

The sequence is names of authors (invert~ame of first author only), year of publication,tItle (lower case letters), abbreviated name ofperiodical, volume, and number of first page.Include name and address (city and state orcountry) of publisher for books. Provide pub­lisher (city and state or country) for conferenceproceedings and conform to either book orjournal format in accordance with the originaldocument. Follow style and form of currentJournal. Serial Sources for the Biosis DataBase, Volume 1990, indicates appropriate ab­breviations.

All reference entries must be cited in thebody of the paper. References must be typeddouble spaced. Abstracts and articles from non­peer-reviewed magazines and proceedingsshould be used sparingly as references. Use ofabstracts published more than 3 years earlier isstrongly discouraged.. Personal communications and any unpub­

lished references should be mentioned paren­thetically in the text. They may not appear inthe references section.

Plan drawings for reduction of 50% or moreto a width of one or two columns to minimizeflaws. After reduction, minimum line size isone point.

illustrations should be submitted no largerthan 21.6 by 27.9 cm.

Original copy should be drawn with Indiaink on white drawing paper, tracing paper, orblue linen. Do not use papers with yellow,green, or red lines for graphs because only bluewill filter out.

computer-Generated Figures

Computer-generated figures are acceptable ifthey meet journal specifications for line width,symbols, and layout. The original printout offigures (rather than xerox copies) is required;do not make glossy photographs of computerprinted figures. Use the highest resolu~on

printer available to you; take care that lettenngand symbols are of sufficient size, scale, andresolution to be legible after reduction. Figuresshould be uniform in scale and in line density(boldness). On line graphs, symbols should notcontain other symbols within them (e.g., a cir­cle within a triangle) to indicate data points,because symbols will fill in upon reduction.When possible, symbols should be defined inthe caption; when the legend is a part of thefigure, it should appear within the axes butoutside the data field Lettering on the y-axisshould be printed vertically along the axis (seeFigure 1). Small dot or line patterns or grayshading will not reproduce evenly. Zerospreceding decimals should be deleted either bymanipulating the software or by manuallyremoving the zeros. Three-dimensional figures,although attractive, often obscure the data pre­sentation; if three-dimensional bar graphs areused, indicate which portion of the bar is to beused for making comparisons.

Electron Micrographs

Authors should submit original plates andhigh grade photographs for reviewers. Micro­graphs should be submitted as near as possible

to desired published size. If micrographs arereduced during the publication process, authorsneed to alter magnification amounts in the fig­ure caption to reflect percentage of reduction.

Color illustrations

Authors should submit specifications to thetechnical editor for estimate of cost as early inthe publication process as possible. Upon re­ceipt of estimate, authors must indicate in writ­ing that they are willing to pay the additionalcost of color reproduction.

TABLES

Tables should be self explanatory and maybe a most effective way to organize extensivedata. Refer to the eBE Style Manual (pp.74-80).

Type each table on bond paper by 21.6 by27.9 cm and place at the end of manuscript.Propose placement of tables in text by circlednote in left margin of typed manuscript.

When possible, tables should be organizedto fit across, not lengthwise, on the page. Beaware of the dimensions of the printed page

when planning tables.Place number and title on the same line

above the table (as shown in sample table). Seeformat of current journal

Use no vertical lines and few horizontallines.

Limit digits to the minimum for meaningfulcomparison within the accuracy of the methods.

Do not use leading zeros (zeros to the left ofdecimals in numbers less than one) in text,tables, or figures.

For each table, spell out first use of abbrev­iations. Abbreviations should conform to Jour­nal style.

Table Footnotes

Footnotes to tables should be numerals.Superscript letters should be used for statisticalanalyses within the body of the table. Probabil­ity may be indicated: tp < .10, *p < .05, **p <.01, ***p < .001.

SYMPOSIUM PAPERS

Instructions are the same as for other papersexcept organization of the text may vary.

ASSOCIATION AFFAIRS 351

Manuscripts with reprinted figures or tablesmust be accompanied by written permission ofthe publisher at the time of fmal manuscriptrevision. An abstract is required. Manuscriptsreceived by ADSA after September 1 of theyear in which the symposium was presentedbecome subject to page charges. Those receivedafter December 31 will not be accepted.Manuscripts must be returned to the editorwithin 3 months after completion of review orthey will not be published with other papers ofthe same symposium.

OUR INDUSTRY TODAY

This section includes interpretive appliedsummaries and recommendations from researchuseful to the dairy industry. Syntheses and ap­plications from technical reports that contributeto solutions of problems in the dairy industryespecially are solicited. Authors of reports forextension education of the nonscientist are en­couraged to share their contributions with col­leagues and to achieve larger circulation oftheir conclusions and recommendations throughthis section.

Organization of papers for Our Industry To­day may vary but should be logical and effec­tive. An abstract is required. Other instructionsto authors apply.

COPYRIGHT AGREEMENT

Upon acceptance of the manuscript, a copy­right release form for each author will be sentto the corresponding author, who has theresponsibility to forward the forms to

coauthors. Authors not permitted to releasecopyright must still return the form signed un­der the statement of the reason for not releasingthe copyright. Failure to return copyrightreleases may delay publication of the manu­script. Copyright releases should be returned tothe Headquarters Office, 309 West Clark Street,Champaign, II. 61820.

GALLEY PROOFS

Galley proofs of all typeset manuscripts willbe sent to the corresponding author. Althoughthe proof appears in a two-column page format,it should be considered a galley proof; pagelayout will change at pagination when the typeis formatted correctly to align columns, adjustheadings, insert figures and tables, etc.

The galley proofs should be read carefullyand checked against the typed manuscript, be­cause the responsibility for proofreading is theauthor(s). Excessive author alterations to thegalleys will be charged to the author. Correc­tions to the galley proof should be made legiblyin ink in the margins of the proof sheets. Editorqueries should be answered on the galleyproofs; failure to do so may delay publication.

Proofs and the typed, edited manuscriptshould be returned within 3 days of receipt.Express mail and FAX transmission (followedby paper copy and typed manuscript) are en­couraged, but returning proofs by first classmail within the US or air mail outside the US isacceptable.

Publication cannot proceed until proofs andcopy are returned.
