Weekly evaluation of bulk tank milk somatic cell counts in Murciano-Granadina goats throughout an entire lactation

Luengo C., Torres A., Contreras A., Sánchez A.

To study the effect of the SCC limit on goat dairy farmers in Murcia, we studied 1173 bulk tank milk samples from 66 goat herds of Murciano-granadina breed obtained weekly. The study period was November 1998-June 1999. The SCC was carried out after 24 hours of sampling with a Fossomatic 90â. Data from herds with at least one SCC for each month was used to simulate the conditions proposed by the European Directive using the limit of 1,500,000 cell per ml. The geometric mean for the entire lactation was 845,000 cell-ml. This was lower than the limit suggested to the EU but close to the legal limit for the US. Data indicate that dairy goat farmers would be penalised during the first and last quarters because of the normal physiological milk SCC response in goats to season of the year. This situation should be considered before the establishment of a legal limit.
