| Popis: | Researches were made on 125 lactations from Romanian Black Spotted cows, aimed at studying the evolution of the interval between calving on milk quantity and quality. Data were recorded and statistically analyzed by means of ANOVA/MANOVA determining the average values and dispersion indices. Based on averages parameters of lactation curves were calculated using the mathematical model proposed by Wood in 1967, called the incomplete gamma function. Lactation curve for lactose percentage was very different among seasons. Significant differences (p |
