The evaluation of estimated breeding value and the most probable producing ability for the basis selection of Ettawa crossbred goat (Capra hircus sp.) at Malang, East Java, Indonesia

Abstract

Ettawa crossbred goat is Indonesia local breed goat that a dual purpose type, namely meat and milk production. The milk production is less but can improve by upgrading with other breeds like Saanen goat. The selection program is an effective way to upgrade the genetic performance of Ettawa goat. The Estimated Breeding Value (EBV) and Most Probable Producing Ability (MPPA) can be considered on the selection program. The purpose of this study was to determine the milk production different and the EBV and MPPA values of Ettawa goats. This research was carried out by survey method on goat farmers. The second lactation of milk production was stated as the data variable. The analysis of variance from nested design showed that any significant different (P < 0.05) in milk production between the district and very significantly different (P < 0.01) between sub-districts of Malang region. The highest EBV was 0.389 L from Bumiaji sub-district as well as the highest MPPA was 0.595 L from Bumiaji sub-district. So, based on the EBV and MPPA values of Ettawa crossbred goat from Bumiaji sub-district of Batu Regency could be chosen as the basis population on the breeding program of dairy milk in Malang region.
