Abstract
The aim of this research was to compare the AC and AT methods (as alternative methods) with A4 method (as
referent 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. Simultaneously, the influence of
the following factors has been tested: year (year of kidding), lactation, month of kidding, milk yield level. It was
determined that the largest deviation in the prediction of milk yield according to the AT method during morning
milking was determined in 2016 with milk yield underestimated for -5.3 L, whereas the smallest deviation was
registered in 2015 with milk yield underestimated for -1.8 L. The largest deviation in the prediction of milk yield
according to the AC method during morning milking was determined in goats in first lactation, with milk yield
overestimated for +3.8 L, whereas the smallest deviation was determined in goats in fourth lactation with milk
yield underestimated for -0.3 L.
With the analysis of all abovementioned factors, it was determined that the AT method is more suitable as al ternative and cheaper method for determination of accurate amount of milk
