• To optimize animal well-being in a socially acceptable and sustainable manner. Never before have producers of animal-based food products faced so many challenges and opportunities. Global demand for animal protein is increasing in response to both population growth and the improving financial status of people in many developing countries. Simultaneously, land and water available for livestock production is decreasing and climate variability is increasing. Costs of feedstuffs have also increased dramatically due, in part, to renewable energy policies that have resulted in competition between bioenergy companies and livestock producers for corn and other carbohydrate-rich grains. In addition, consumer sentiment and associated legislation often govern animal management practices without regard to cost and efficiency of production and cost of food to consumers.


INFORMATION FOR CONTRIBUTORS TO ANIMAL PRODUCTION
Detailed notes for guidance in toe preparation of manuscripts are printed in Volume 13, pages ix to xx. A few general points are given below.
Animal Production publishes papers on original research provided that they have not been and, with the exception of authors' summaries, will not be published elsewhere without the Editors' written permission. Authors' summaries can be reproduced if full acknowledgement of the source is made.
Contributions may be in the field of animal production, or in any related scientific field. Reports on techniques will be published only as appendices to scientific papers. Results of research which do not warrant a comprehensive presentation may be submitted for consideration as Notes. Notes are not intended for the publication of interim results. They should not exceed 2000 words or the equivalent inclusive of tables and illustrations.
Manuscripts should be typewritten in double spacing with wide margins. Each page and the lines on each page should be numbered.  On p. 2 in the section on Ration composition and feed scale the first sentence of the fourth paragraph should be amended to read: 'The planned feed scale was 1 kg meal at 23 kg live weight increasing to 2-3 kg at 45 kg live weight, above this weight the allowance increased by 0-5 kg per 20 kg increase in live weight.' terms of use, available at https://www.cambridge.org/core/terms. https://doi.org/10.1017/S0003356100011302
