výroční zpráva 2009 ( 4,12 MB ) - Zoo Ostrava

for the lemurs, where the family of the "blue-eyed" stayed until the middle of September 2009. Sadly, thehealth of the breeder Micha, who in terms of genetics was the most valuable lemur of the species in Europe,started getting worse at that time and became paralysed with time. Because of the rareness of this lemurspecies, we had the male examined at a special clinic in Brno, unfortunately with fatal findings - two spinalvertebrae had been attacked by cancer causing the animal's spinal cord to depress with subsequent paralyse.As such state was impossible to treat, Micha had to be euthanised, leaving only the breeding female Melanieand the young Ravu at Ostrava Zoo. Due to the urgent reproductive situation in these lemurs, we could notafford leaving Melanie without a male during the oestrus period, which takes place only once a year, fromDecember to February. Upon agreement with the programme coordinator and having undergone a slowpaperwork process, Ostrava Zoo successfully imported another Sclater's lemur pair from Poznan Zoo. Eventhough both animals had reached 10 years, the pair never reproduced, despite lemurs can start to reproduceonce two years old. Factors affecting this failure might have included the dietary status, as both animalssuffer obesity, weighing 3.5 kg, while normal weight is 2 kg approximately. Now, the transfer mentionedabove has brought new perspectives for everyone involved. The new female Fuoro was paired with the youngmale Ravu and chances are they will breed successfully in the subsequent season. The female Melanie andthe new male Saroh even already mated, giving everyone the hope of another happy year for Ostrava Zoo andtheir rare lemurs in particular.Note: the figures in brackets stand for numbers of animals, where the first digit gives a number of males,the second that of females and the third digit means a number of animals with sex not yet determined, whereapplicable.45
