Uso de sensores de efecto Hall para registrar la cinética de emisión de leche: caso de estudio automatización del wb mini-test en ganado Caprino.

We have designed a team with Hall effect sensors, meters installed in proportional WB Mini-Test allows us to automatically record the emission kinetics and the total milk production in goats milked. The electronic system is inexpensive (about 80 euros of material) and has overcome the difficulties that exist in this type of measures (effect of the composition of milk, the presence of foam, transportable, temperature, washing etc.). With the standardization of data, one of the two calibrations created a very good estimate (standard error of estimate = 29.8 ml R2 = 0.9992) was achieved. The fact that the estimation error does not vary depending on the day and the game of milking small differences and present order of the volume of milk obtained, suggesting it could be used in dairy farms control goats.
