In India, Muraleedharan et al. (1999), Patel et al. (2007), Kumar (2009), Mahdi et al. (2010), and Yathish et al. (2010), Patel et al. (2010) have reported the carrier animal’s frequency of 1.33%, 3.23%, 21.82%, 7.31%, 3.64% and 4.76%, in Holstein animals and its crosses respectively. However one recessive homozygous (affected) Karan Fries bull was also observed by Yathish
et al. (2010). The incidence of BLAD carriers among top sires was found to be 23 % in USA (Shuster et al., 1992), 10% in France (Tainturier et al., 1995), 13.5 % in Germany (Biochard et al., 1995), 2.88 % in Argentina (Poli et al., 1996), 16 % in Japan (Nagahata et al., 1995),
2.8 % in Brazil (Ribeiro et al., 2000) and 3.33% in Iran (Norouzy et al., 2005). In our present investigation the frequency of carrier animals was found as 1.59%.

Di India, Muraleedharan et al. (1999), Patel et al. (2007), Kumar (2009), Mahdi et al. (2010), dan Yathish et al. (2010), Patel et al. (2010) telah melaporkan frekuensi pembawa hewan 1,33%, 3,23%, 21,82%, 7,31%, 3,64% dan 4,76%, pada hewan Holstein dan persilangannya masing-masing. Namun satu resesif homozigot (terpengaruh) Karan Fries bull juga diamati oleh Yathish
et al. (2010). Insiden operator BLAD antara indukan atas ditemukan 23% di USA (Shuster et al., 1992), 10% di Perancis (Tainturier et al., 1995), 13,5% di Jerman (Biochard et al., 1995) , 2,88% di Argentina (Poli et al., 1996), 16% di Jepang (Nagahata et al., 1995),
2,8% di Brazil (Ribeiro et al., 2000) dan 3,33% di Iran (Norouzy et al., 2005). Dalam penyelidikan kami saat ini frekuensi hewan pembawa ditemukan sebagai 1,59%.
