Study of milk production indices of Bălțată românească exploited in farms in Neamț county

Abstract

In this paper we analyzed the milk production indices, for normal lactation (305 days), on the first two lactations of Spotted Romanian cattle breed in two farms in Neamț County. To aim this, we used data from the Association of Cattle Breeders from Mureș County accredited for performing our own performance control (CPP) as well as data from the Genealogical Register. For the analysis of the productive performances, statistical processing of the primary data regarding the average value and the variability of the milk production indices for 4 characters was carried out, as follows: length of normal lactation (days), quantity of milk per normal lactation (kg), percentage of fat, and percentage of milk protein. The studied farms were coded with Arabic numerals: darm 1- I.I Ciucalău Aurelia Vasilica, and farm 2 - P.F.A. Pintea Ionela. The best productive performances were registered in farm 1, where the average milk production for the first lactation was 5967.80 kg, the average value of the fat percent was 4.08%, and the average value of the protein percent was 3.26%. At the second lactation, the average milk production was 5012.89 kg, the average value of the fat percent was 4.05%, and the average value of the protein percent was 3.31%. In the first lactation the average milk production per normal lactation was 5967.80 kg, but it decreased in the second lactation to 5012.89 kg.
