Economical Analysis of Ablactation of Eastern Anatolian Red (EAR) Calves in Different Periods

Abstract

In this research, economic analysis of ablactation of Eastern Anatolian Red calves in different periods was made under the conditions of Firat University Research and Implementation Farm. In the research a total of 21 pedigree Eastern Anatolian Red Calves were used in three different groups, each group included 7 calves.  The calves ablactated in the 5^th month and used as control group consisted the 1^st group, the calves ablactated in the 4^th month consisted the 2^nd group and those ablactated in the 2^nd month consisted the 3^rd group. In formation of each group, it was paid attention that calves with the closest birth weights and birth dates were selected. When live weights of groups in day 180 were examined in the research, it was determined that the live weight value of the 1^st Group was 86,07 kg, that of the 2^nd Group was 99.93 kg and that of the 3^rd Group was 86.93 kg.  To make an economical conclusion, total milk and feed cost was found for 1 kg of live weight gain and this cost was determined as 632.08 TRY for the 1^st group, 716.27 TRY for the 2^nd group and 920.89 TRY for the 3^rd group.

As a result, it was determined that the ablactation time in which consumed milk and feed amount is most economic for both live weight increase and 1 kg live weight gain is 120 days.
