To implement our method 26 goats belonging to the Canary Caprine Group were monitored post-partum (sample 0). During the first five days, ten samples of colostrum were obtained with a 12 hour time period elapsing between each sample-taking. In each colostrum sample, the colour (CIE L*a*b* system), the IgG concentration, the density, the conductivity and the chemical composition were measured. The results show that the b* co-ordinates (positive values indicate yellow-tending tones, negative values representing blue-biased hues) were the best predictors of chemical and immunological composition of colostrum, better even than density. The correlation's coefficients between b* and IgG, % proteins, % lactose, % fat were 0.89, 0.68, -0.70 and 0.71 respectively. Therefore the correlation found can be used as a field method in the early detection of colostrum poor in energy and immunoglobulines.||URI:||http://hdl.handle.net/10553/52848||ISBN:||90-74134-84-X||ISSN:||0071-2477||Source:||Livestock Production And Climatic Uncertainty In The Mediterranean[ISSN 0071-2477] (94), p. 129-131|
