100% Organic Livestock Feeds – preparing for 2005 Organic Eprints
Hancock, Jake; Weller, Richard; McCalman, Heather.
A project entitled “100% Organic Livestock Feeds – Preparing for 2005” looking at the implications for organic farmers of the removal of the current derogation to use a percentage of non-organic livestock feeds. 1) Researching the required volume of feed stuff, in particular protein crops, and potential for feed production within Wales. 2) Researching the suitability of alternative protein sources, and evaluating livestock systems regarding the potential for a reduction in energy and protein levels. 3) Proposing strategies for the development and stimulation of the industry.

Comparison of the physical and financial performance of organic dairy farming systems (OF0146) Organic Eprints
Weller, Richard; Nicholas, Philipa; Fowler, Susan.
This is the final report from Defra project OF0146 Two different systems of organic milk production were studied during the 1998-2002 period. The systems were established at the IGER Ty Gwyn organic dairy farm during the 1998/99 period. The systems were based either on achieving self-sufficiency in both home-grown forage and concentrate feeds or on the production of home-grown forage and the purchase of concentrate feeds. The data collected included recording the changes in the soil indices, level of crop production, crop quality, level of milk production, milk quality, animal health and herd reproductive performance of the two systems. The main attached report starts with a detailed executive summary. In the modelling work fifty-four different...

Organic Dairy Farming Organic Eprints
Weller, Richard; Jackson, Andrew.
The technical guide addresses the issues relevant to the organic dairy sector sector, acknowledging the questions that are frequently directed to the technical ‘Helpline’ of Organic Centre Wales. It is intended as a guide document for those with an interest in organic dairy production and points the way to those who wish to look in greater depth at the issues raised. This guide is in three interrelated parts. The first part, written principally by Richard Weller of IGER, deals primarily with technical issues of grassland and dairy herd management, and provides practical information for dairy farmers on key factors influencing the performance of the system and also provides options for changing to alternative strategies. It draws heavily on studies at...

Organic Farming in Wales 2003 - 2004 Organic Eprints
Fowler, Sue; Green, Michael; Hitchings, Roger; Jedwell, Andrew; Kennard, Bob; Little, Tony; McCalman, Heather; Pearson, Neil; Powell, Jane; Rowlands, Gareth; Spiller, Gary; Thomas, Huw; Wacher, Carolyn; Weller, Richard.
Organic Centre Wales (OCW) was originally formed to act as an information source for producers enquiring into organic farming; in our second phase, in response to changes in the sector, we have an increased remit on policy issues. It has been a busy time, seeing the production of a second Organic Action Plan, the implementation of the CAP reform and development work on agri-environment reforms. The year also saw the start of organic maintenance payments for farmers. This Annual Report contains accounts of the progress that has been made on many fronts during the last 12 months, particularly in market knowledge due to the research for the recently published report, 'Organic Food: understanding the consumer and increasing sales'. This information,...

The effect of diet on the milk quality of organic dairy cows Organic Eprints
Weller, Richard; Davies, Robert.
This report was presented at the UK Organic Research 2002 Conference. Changes in milk quality were evaluated with spring-calving dairy cows and heifers fed organic diets and different levels of concentrates during early lactation. The diets were based on ad libitum forage and either 2 kg of concentrates/day (Diet 1) or concentrates fed according to milk yield up to a maximum of 7 kg/day (Diet 2). Average milk yields during the study for the cows and heifers were 23.1 and 20.1 kg/day (Diet 1) and 25.8 and 24.0 kg/day (Diet 2), respectively. The highest number of samples with a fat to protein ratio of 1.4 or > were found in samples collected from cows and heifers fed Diet 1 (20.9 and 50.0%). The lowest milk protein value of 2.86% was recorded from the...

The validation of a computer simulation model for use in organic dairy farm systems in the United Kingdom Organic Eprints
Nicholas, Phillipa K; Padel, Susanne; Fowler, Sue; Lampkin, Nic; Topp, Cairistiona F E; Weller, Richard.
This report was presented at the UK Organic Research 2002 Conference. On organic dairy farms, computer simulation models can be used to predict more rapidly and at less cost than field trials the outcome of changes to management strategies or physical resource inputs. Such models need to be validated with data from existing organic dairy farms to ensure that the predictions made are realistic. As part of a larger organic dairy farm modelling project, this study will use data from 2 contrasting organic dairy systems at Ty Gwyn research farm, to validate a whole farm dairy system model developed by the Scottish Agricultural College. The model will be used in future work to identify the most productive and resource use efficient organic dairy systems across a...
