Fertility and fertility management in thirteen well-established organic dairy herds in the UK Organic Eprints
Hovi, Malla; Taylor, Nick; Hanks, James; Roderick, Stephen.
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR). Milk production and breeding records from thirteen organic dairy herds were collected between January 1997 and December 1999. Mean lactation yields in the herds ranged from 5127 kg to 7031 kg. Whilst seasonality of calving varied widely between herds, a majority of them (6/13) were autumn calving. Mean calving to first service interval was 80 days (range 68 to 97), and mean calving interval was 385 days (range 370 to 413). The mean number of services per conception was 2.3 (range 1.6 to 3.1). Overall culling rates and culling rates for fertility related problems were at 15.8% and 5.4%, respectively. A preliminary study of selected breeding...

The productivity of organic dairy herds Organic Eprints
Roderick, Stephen; Hovi, Malla; Taylor, Nick.
This report was presented at the UK Organic Research 2002 Conference. Organically managed ruminant systems place particular emphasis on maximising production from forage. Therefore, it is important that efficiency measures take full account of forage inputs. The Livestock Production Efficiency Calculator (LPEC) calculates the total metabolisable energy (ME) required by livestock and estimates forage inputs as the difference between total requirement and that supplied by other measured feeds. Productivity is expressed in terms of output (£) minus other valued inputs (£) per unit of forage ME. Estimates of production parameters were used to produce productivity indices for thirteen organic dairy herds. The productivity of herds was compared, and sensitivity...

Small mammal survey on agricultural land during conversion and into full organic production Organic Eprints
Burke, Jean; Taylor, Nick.
This report was presented at the UK Organic Research 2002 Conference. Loss of food and suitable habitat due to modern intensive farming and the decline of mixed farming systems has lead to a reduction in numbers of small mammals on farmland in the UK. Organic production systems are believed to encourage biodiversity. Small mammal surveys were carried out on Coswinsawsin Organic Demonstration Farm in November 1999, April and November 2000 and October 2001. 50 Longworth traps were set in pairs at 5 metre intervals along a hedgerow and checked morning and evening for three days. Trapped mammals were identified, weighed and with the exception of shrews, marked by a small fur clip before release. The wood mouse was the most prevalent species trapped. Other...
