Livestock Research for Rural Development Volume 33, Number 12, 2021

Notes to Authors

LRRD is fully OPEN ACCESS, with no publication charges, on the principle that research findings related to sustainability of farming systems should be freely available in the public domain.
Papers may be copied and reprinted freely.

Important Announcement

We advise all authors planning to submit papers to LRRD that we will no longer publish papers based on research in which the welfare of animals was compromised by surgical modification or the use of methods that generate stress and discomfort. These include procedures that modify the digestive track that were mostly developed to facilitate measurements of digesta flow in both ruminant and monogastric animals. We believe that these procedures are no longer relevant in view of developments in in vitro systems for which sources of microorganisms can be obtained from slaughtered animals.

We trust that readers of LRRD will agree with us since the welfare of animals is of primary concern and should not be jeopardized by surgical or management procedures which cause serious discomfort to the host animals.


The LRRD Vision

The future requirements of society for food and energy can best be met from integrated small to  medium family farm systems in which:

·         most resources are produced locally, 

·          the direct and indirect use of solar energy is maximized,

·         all wastes are recycled;

·         the carbon footprint is negative; 

·         there are overall environmental and social benefits.


The LRRD mission

To promote local research on the:

(i)                 use of local resources for live stock production in ways that are non-competitive with human needs;

(ii)               development of systems for producing renewable energy by:  

a.       biodigestion of animal and human organic wastes;

b.      gasification of dry fibrous residues from crops grown primarily as food/feed for humans and live stock;

c.       increasing use of draft animal power

(iii)             promotion of indigenous live stock breeds that have high reproductive rates and adaptation to use of local feed resources and local climatic conditions;

(iv)             regeneration of soil fertility through promotion of tree crops and recycling of organic matter

(v)               development of  emerging markets for ecosystem services, such as carbon sequestration and nutrient sequestration.

(vi)             promotion of “farmer“  markets for food produced in environmentally  friendly and socially just, family-oriented small-scale farming systems

(vii)           improving the efficiency of use of water

(viii)    recycling of wastes


Guide to Authors

Papers should be sent by E-mail to the Senior Editor. reg.preston@gmail.com. If acknowledgement is not received within two weeks then authors should send a reminder to the Senior Editor with copy to preston@lrrd.org.

The papers should be sent by e-mail as an attachment, and with "LRRD" in the subject line. Email messages with attachments and unknown subject lines are not opened in view of virus risks.  

The principle tool for publishing the journal is Microsoft Office. This is the preferred format for receiving papers and short communications.

Authors should examine carefully  the Notes to Authors that appeared in the last issue of LRRD and strictly follow all the instructions.

Lack of respect of these instructions may lead to the rejection of the paper


Key words

Do not repeat the words already in the title of the paper. Search engines such as Google automatically search the title. Key words should draw attention to features of the paper not addressed in the title.  .


Body of Text

- For Page Set up Use: Paper size A4 and Margins 2.5 cm
- Use the font "Times New Roman" 12 pt.
- Do not use full word capitals for titles nor for names of authors.
- Include your e-mail address below your postal address in the Title
- Indicate the Keywords after the Abstract in alphabetical order
- Separate the Titles and associate-titles from the previous and next lines by an empty line, using the ‘return’ or ‘enter’ key
- Do not use numbers such 1.; 1.1.; 1.1.1.; to mark the Titles and Sub-titles.
- Separate each paragraph by an empty line, using the ‘return’ or ‘enter’ key
- Make sure the paragraphs are aligned to the left not  “justified”
- Do not use an indent in the beginning of each paragraph


In text and tables

Ensure that numbers in tables and in the text contain only three digits after or before "000"
eg:
234.21 becomes 234
1.2367 becomes 1.24
0.00032176 becomes 0.000322
0.01 should be 0.00712
for R2 only two digits after or before “00... ”
eg: R2 = 0.677 becomes R2 = 0.68


Tables

Please format them using the Table menu, and not Tabs and Spaces
- when using the tabular format please allot a new cell to each piece of data.
- include the title of the table as well as the notes at the bottom of table inside the Table itself not in the body of the text.
 - when comparing treatments
in a balanced design do not give SE of each mean. SEM of means is more appropriate with the exact probability as given by the statistics program. The SE of each mean is appropriate when nunbers in each mean are not equal.


Statistics

Avoid use of the term "significant". If "A" is greater than "B" then p <0.05 is understood and the exact level of probability  will be in the table.  The accepted symbol for probabiliity is p.  P is  for Phosphorus. Note:  p=0.065 but p<0.001.  A tendency for a difference to be significant is when p >0.05 and p <0.10 and the exact probability will be in the  text (eg: p=0.058).

There were numerical differences .... (..is not allowed)

Check that the URL is complete (it means that it leads directly to the article, not to the Journal Home Page), is correct and is functioning. By clicking on it: it should lead you to the Web site.!

PLEASE:

- Use the Spell-Check tool in order to correct any spelling mistakes, and

- Ensure that references in the text are in the reference list and vice versa.

An easy way to check this latter point is to print the reference list and then from the beginning of the text to use the "FIND" command and type "19" and then "20". This will locate all the references assuming you have cited correctly the source including the date.

The reviewers appreciate the pressure put on academics to publish in order to maintain their positions. This very pressure should, however, encourage authors to be more rigorous in their presentation.  If they evince a lack of interest in accuracy they should not expect that increasingly frustrated referees, giving freely of their time and experience, should contain their frustrations and make the paper accurate for them.


Proof reading of papers

Each paper as it is edited is being made available as a provisional "url" which is communicated to authors when the final version of their paper is ready in html format. Authors can then check the paper for possible errors or last minute corrections and inform the editors accordingly. Queries on the proofs made by the editors are indicated in "red" (suggested rejection) or "blue" (suggested additions or changes).

Authors sending corrections to the proofs should send an email to the Chief Editor in the following format:

Do not send a copy of the whole paper as this would require the editors repeating the whole process of conversion to HTML format, which can be quite time-consuming.
