You both raise a number of good points.
As a region, we have three matrilines:
1.
Porntip (1992):
Kanlaya (2018)
2.
Dokkoon (1993):
Mali (2010) and
Aiyara (2022)
3.
Num-Oi (2001):
Kati (2023)
If Anjalee’s calf due next month is female, we may have a fourth:
4.
Anjalee (2006):
Unborn (2025)
Another ended with the death of Pak Boon’s daughter in 2018:
0.
Pak Boon (1992):
Tukta (2010-2018)
You’re correct that having multiple matrilines at a facility is not ideal and has led to conflicts within herds in Europe. Ultimately it’s been a catch 22. The ideal scenario would have been for a matriline to flourish at each facility; but of the seven cows imported (six of which have bred), I would only describe Dokkoon’s matriline as flourishing. One cow (Tang Mo) never bred; another (Thong Dee) produced only sons; a third (Pak Boon) lost both calves before they reached maturity; a fourth (Kulab) is a non-viable breeder after producing one son (and suffering a prolapsed uterus). Porntip and Num-Oi’s young daughters will hopefully survive to breed; but both matrilines remain precarious until this is achieved.
The 7-8 year birth intervals have been undesirable. As
@Zorro notes, an expanded barn facility at Dubbo would have been invaluable in expanding the herd, which is progressing at a slow rate at present (with a possibility two viable cows have been retired from the breeding programme).
Monarto have the greatest challenge of all in integrating four cows from three herds. Ultimately options on where to send these cows were limited and it could be perceived that they acquired them on humanitarian grounds. I for one am grateful the valuable founder bull (Putra Mas) is to remain in the region. Having these older cows at a (potential) breeding facility may compound rifts in the herd; though it’s worth noting Pak Boon isn’t even pregnant yet. It could easily be 15 years plus before she has the support of adult daughters, by which time Burma and even Permai may no longer be around.
