THE EVOLUTION OF THE MAIN TRAITS OF THE MILK PRODUCTION BY CONTROLS AND DYNAMICS BY LACTATION
Keywords:
milk, technology, Romanian Spotted, dynamicsAbstract
The research was performed during 2002-2007, on 317 Romanian Spotted cows,
from five private farms and one on ASAS ownership, located in two rearing areas
from the central part of our country. By total effective, areas and farms, the dairy
production from the control day was emphasized, by milking period and total, its
content in fat, protein and lactose, respectively, by dynamics during four lactations,
mentioning that the interesting indices were also detailed by four levels of the dairy
production in first control. The results led to the first conclusion, according to such
studies must be performed in any rearing farm or exploitation. Their evolution, in
dynamics by controls, emphasized the efficiency of the adopted technology of
exploitation and nominating of the chains that must be improved. According to the
processing of the results, the indices that contribute to the simplifying of the
diversified control of the dairy production were nominated, with the aim of preselection of the cows for C.O.P. network or the production level of those that are
not included in above mentioned network, but can be used for the specific rearing
aims and more suitable mating.
