A brief Statistical Analysis Regarding the Fat Content of Milk Obtained from the Holstein and Simmental Breeds

Abstract

The purpose of this paper was to carry out a short statistical analysis on the fat content of milk from two breeds of cattle from a farm in the Moldavian area. 30 milk samples were analysed, more precisely 23 from the Holstein breed and 7 from the Simmental breed in two periods, such as the cold season (autumn-winter) and the warm season (spring-summer). It is known that these breeds are among the best breeds of cows for milk, the first being considered the most productive in the world, and the second the best breed of cows for farms in Romania. The Holstein breed is a highly specialized breed for milk production, while the Simmental breed is a dual-purpose breed selected for both meat and milk production. Following the statistical analysis, it can be seen that there were significant differences between the two breeds of cattle studied and also between the milk fat content recorded in the cold season compared to the fat content recorded in the warm season. The value of P was less than 0.0001, confirming the heterogeneity of the data recorded in the two seasons. The main conclusion is that for the total experiment, the data are significant (alpha=5%).
