Abstract
Accurate and precise milk recording is one of the most
important moments for a successful selection of milking goats. In this context,
breeders are constantly making efforts to find the most suitable and cheapest
methods for conducting of tests for milk production. The goal of this research was
to compare the A4 method (as referent method) with AC method (as alternative
method), for determination of milk production, on the day of recording of the
indigenous Balkan goat, in the period of 2014-2016 with milking of goats in the
morning and evening. It was determined that the difference between the predicted
daily milk yield with one milking (in the morning or evening) and the measured
milk yield using the A4 method is too low and almost negligible. With the analysis
of all factors (year, lactation and number of milk tests), it was determined that the
prediction of total daily milk yield, based on the evening milking, provides more
accurate result, in relation to the prediction during morning milking, in cases when
using the AC method.
