A Colorado Rat Breeder-Camarattery

The Sprague Dalwey's are here from Isbn! Please see their page for more info.

I have a line of Sprague Dawley rats coming in a couple of months. These are from a rattery I am mentoring, being a nurse was able to get them from work at the hospital with the ever so extensive pedigrees included.

--

Sprague Dawley are a line of lab rats bred for health, strength and vitality. They typically live 3.5 years. They are PEW hooded rats. They are a General-purpose albino stock. A  very docile,outbred rat. They are resistant to many of the things they are tested with. So they are very healthy, and their genetics of course are very well documented and mapped. So in laymens terms, they are not going to add anything negative into my lines. They can in fact clean my lines of any issues that are present that I don't know about. Of course I wont just breed them into my lines in good faith with out testing them for several generations 1st like I always do. Because I need to see if I like them 1st. But I am thinking I will.

I also really want a line of PEW Dumbo rats. They are a passion of mine.:P And I need them to clean up the hoodeds I have. Or just to replace them in general.-I prefer the latter.

Definition of an outbred stock (http://www.isogenic.info/html/outbred_stocks.html)

--

An outbred stock is a colony of laboratory animals within which there is some genetic variation, which has been closed for at least four generations. It is usually maintained to minimise inbreeding, which should not normally exceed one  percent per generation. This can be achieved with random mating using at least 25 breeding pairs per generation. A breeding scheme which ensures  that each breeding male is represented by one male, and each breeding female is represented by one female in the next generation can halve  these number. Usually this is achieved using a rotational breeding  scheme. However, most commercial colonies are maintained with hundreds  or even thousands of breeding animals where genetic drift due to  inbreeding is likely to be minimal, but the stock characteristics may  change as a result of selective breeding (e.g. for fast growth rate) or  genetic contamination (i.e. getting two stocks mixed).

I have a new line of marked rats. I will post them to my site once they are out of quarantine.

--

I also have a new line of Pearl merles and Mink Merles! These will need to be bred for self as they have markings right now.

H2R in the Springs will be working on the marked rats too!

Update: They are posted. They are non High White (safe) Dalmatians!

It has been a great year for Camarattery. Our lines are back in full force and better than ever. Their life spans are still twice the average and the type is getting better and better.

We are done bringing in new blood for the year. But we wanted to once again thank the breeders who shipped to us this year.

Connie from RG sent us 2 shipments this year.

Amanda from RAMR sent us 1 shipment this year.

Shari & Dawn of BHR sent us 1 shipment this year.

Thank you everyone! All of the rats came in super friendly and very, very healthy. There was not a single health issue with any of them.  We could not be happier with the rats. Of coarse its been quite a while since these rats came in, but we did want to end the season with a big thank you to all of you!

THANK YOU!

Outbound shipments this year went very well also! We did send out several boxes full of babies for other breeders to work with. We are always very happy to help progress the rat breed.

Welcome new rats!

We had another successful airline shipment! I have posted pictures already. We had sent some of our old good lines to Arizona to RAMR for an outcrossing, and we have brought back some wonderfull 1/2 Cama and 1/2 RAMR lines. Since both of our lines have longer life expectancy than the average rat and great helath and lovable temperaments, we know these will continue to lock in those desireable traits. This is the 3rd time we have done this with the RAMR lines and we are always very pleased with the results. I have been working with the RAMR lines since March of 06 and had nothing but the best success with every one of them. So much so that I embrace them as I do my own lines. I know that I can trust them without any doubt.

I want to thank Amanda of RAMR for doing this for us again...! And a big thanks goes out to Donna of GRIM rattery for shipping them to us, and keeping them for a few weeks!

Also I know I speak for Karen of H2R when I say thank you! Karen is just going to love her new rats as well!

Also one last comment, Yay! My old Rex line is back once again! We love our Rex gene because it won't breed bald doubles, just thicker hair but much curlier. You can't get our Rex gene elsewhere. Viva La our Rex Gene!
