Boa constrictor Kahl albino Motley

English name
Albino Motley (Kahl strain)

Morph
Inheritance: Simple recessive and co-dominant mutations

Size
The average size of a adult female Boa Constrictor is about 1.90 – 2.20 m. Males are a bit smaller.

Overview
Albino motley Boas were produced by combining the Kahl albino gene with the Colombian motley gene.
Complete absence of any black/dark pigment. Red pupils and pink tongue.
Connecting dorsal pattern often displaying a striped or ‘squaretail’ appearance. Absence of belly speckling and typical ‘diamond’ pattern to the flanks, generally replaced with lateral striping.

Housing
The boa constrictors are housed in cages build from shuttering plywood 125 cm long, 75 cm wide and 60 cm high. I use newspaper as a substrate.

Temperatures 
The temperature gradiënt varies between 24-26 degrees Celcius on the cool side with a basking site of
30-35 degrees Celcius. During the breeding season gradiënt between 21 degrees celcius and 26 degrees celcius.

Humidity

Humidity around 60% – 80%.

Lighting

The light period being used is 12hrs on and 12hrs off. When using lights also as heatsource make sure you put the light to one side of the enclosure. So don’t put it right in the middle. By putting it to the right side or left side of the enclosure you will create a warm side and a cooler side of the enclosure. This way your boa can choose for himself/herself what they want. Also put the waterbowl on the cool side of the enclosure, don’t put it underneath the light, this may cause waterrot. We use 40 watt lights, this creates about 30-35 degrees celsius as a hotspot.

Feeding
Newborn boa’s will feed mostley a few days after the first shed. Feeding from newborn untill the age of 2 years old it’s very important to feed every 7 days only proper sized preys. After 2-3 years they can be fed every 2 -3 weeks a big rat.

Sexing
A male boa will typically probe to a depth of 6+ sub caudal scale whereas a female will only probe to a depth of 2-4 sub caudal scales.

Breeding
Sexual maturity in boas is typically reached at 18 months for males and 30 months for females.
Your breeder Boa Constrictors should be put through a cooling or cycling period to help stimulate the breeding cycle. Before your Boas enter the cooling period it is crucial that they are in robust health and have no lingering health issues that could flare up under cooler temperatures. During cycling night time temperatures are lowered to the mid to high 21 degrees celcius with daytime highs of mid to high 26 degrees celcius we continue to feed both males and females, but feed smaller less frequent meals. All other basic cleaning procedures stay the same.
After roughly 3-4 weeks of the cooling regime, we begin to introduce males into the female’s enclosure.Courting can sometimes happen immediately but can also take several weeks. During courting the male boa will be incessant in his actions, he will ‘scratch’ the females body with his spurs and be in constant contact with her. Once the female is receptive copulation will take place but is not always observed as it is often very difficult to see actual penetration of the hemipene. Once copulation is suspected, there are several tell-tale signs that indicate that the female is gravid. The first sign is an increase in girth; this is the females’ body getting ready for the actual event of ovulation. A gravid boa will usually refuse all feeding attempts, but it is still a good idea to offer a meal perhaps every 2 weeks but ensure that the food is significantly smaller than her usual meal. Once a female is gravid you may also notice a change in her behaviour, she will coil very tightly on the warm side of her enclosure and may in fact not move from this position for a number of days. Once a female has ovulated she enters a shed cycle, this cycle will happen about 15-20 days after ovulation, and this is the best indicator for when to expect your litter of boas. It is important to record all significant dates, such as ovulation and her post ovulation shed (POS). The average amount of days to pass from her POS and the birth date is 105 days.
