Bart the Bunny and evaluating bunnies at 8 weeks

Here is Bart, who goes to live with Trish this weekend. He is a real cutie and has been growing like a weed. His demeanor is calmer than his bigger brother, and I think Trish will like him.

Today I weighed all the 8 week and 3 week bunnies as some are leaving this weekend. I like to keep records of litters at this age to see which direction my breedings are going in. This is only the first step in a long series of checkpoints as I evaluate potential breeding stock. Some folks in the industry call this the first culling, and although that can be correct, "culled" rabbits here are simply ones that are removed from the breeding agenda and are designated pet/fiber quality.

So in Gretchen's litter, the three weighed 2# 15 oz; 2# 15.8 oz, and 3# 9 oz. Since the German standard is a rabbit that is around 10 pounds (I don't have the standards in front of me...there is a range) I generally pick the biggest and fastest growing bunnies as keepers. In this litter that is a black buck. So he gets a name and his own cage this weekend.

In Grindle's litter, we have 4 weighing 2# 15 oz; 2# 15.8 oz, 3# 1.2 oz and 3# 5 oz. The biggest one is a tortoiseshell doe, and she will get her own cage and name this weekend, also.

Sydney's 3 week old litter has a range from 6 oz to 10 oz. The little 6 oz buck will indeed be pet quality. He is just adorable and has great spirit, but is not filling out like his siblings. Sometimes these little ones do not do well after weaning, but I'll keep an eye on him and we'll see where he goes.

Rabbit Hemorrhagic Disease in Indiana...READ THIS!
Anyone with rabbits, any kind of domestic or feed rabbits, should take a few minutes to acquaint themselves with the symptoms of RHD(Rabbit Hemorrhagic Disease), also known as RCD (Rabbit Calcivirus Disease) and VHD (Viral Hemorrhagic Disease). This disease kills rabbits in less than 2 days. Agricultural authorities are very concerned when it flares up in the US, and it just did this week in Indiana. You can read the press release from the Indiana State Board of Animal Health , which lists the symptoms to watch for. This disease has been identified in the world since 1984. There is no cure, and the only vaccine available is not allowed in the US for many complicated reasons.

Here is the problem with this disease; it can be in Indiana today, and with folks traveling for the summer, in California, New York, Texas, Florida or Maine tomorrow. The virus that causes this can live on infected clothing for over a month. It is carried from sick rabbits on shoes, on feed, on cages, on clothing. You get the picture. There is no cure, and entire herds are euthanized when it is in the neighborhood to be on the safe side.

They suspect the original infected rabbits were purchased at a flea market in Kentucky and brought to Indiana a week/two weeks ago. Facts are still uncertain. For this reason, I am closing my barns to the public until 8 weeks have passed with no new cases appearing.

In all likelihood the health department will get a handle on this before too many more rabbits die. The last outbreak in 2001 saw the euthanization of over 600 rabbits in 4 states before they saw the disease halt.

If you have a rabbit that gets listless and begins to bleed from any body opening, call your vet.

New arrivals :)
Topic: black
Two new bunnies have arrived this past week from other angora rabbit breeders. I find it healthy to keep improving my breeding program with new genetics.

Grijsje (Dutch! a color name for grey/charcoal I am told) who's pronunciation is "greet-cha" as far as I can tell, arrived from Charlene Schultz. Two years ago, Charlene sent the beloved and now lost Zwart, and Grijsje is related to him. His job description includes becoming a stud muffin for 6 does, should his stay here prove fruitful. He is a character and I can tell Charlene has loved him alot. His fiber is incredible for his age (13 weeks!)

And from The Spinning Bunny came this feisty little thing:

Lucinda traveled with Alice from Wonderland Dyeworks and spent a few days with Shelia and Jen from Spirit Trail Fiberworks on her route to me. When she arrived I was totally amazed at her luscious black color and her deep, dense fur. From traditional German Angora lines, this sweet thing is simply perfect. She spends her days tossing her food bowl, which Shelia and Jen informed me is what she did with them.

Both bunnies will be in quarantine for 6 weeks as they settle down from the move and become accustomed to the new germs here. This is a precaution for them as much as for my herd, and allows everyone to live a calm lifestyle for a while before joining ranks. And it's fun for me to spend time with them alone after I have fed and watered the rest of the herd.

Sidney's litter at 13 days

Yesterday was "Rabbit, Rabbit Day" in our house. On the first of each month, we all chant that phrase upon awakening, for it is supposed to bring good luck all month if that is the first phrase you utter this day.

Sidney has been SO protective of this litter, that on this Rabbit Rabbit Day, their 13th day of life, I was surpised to see them just throw back the nest covering and exit. It was unreal. AND mama let me snap pictures to my heart's content.

I have had a complete charge of heart about this rabbit, as she has had a personality transformation since the bad delivery 8 weeks ago. When breeders tell you that rabbits can change after having a second litter, add me to the ranks of those who believe them.

I love angora rabbits. I cannot imagine my life without them in it. Peaceful, beautiful, and after their angora fur is spun into yarn and knit...warm!

Genetic calculator
Topic: color genetics
It is always a guess what any two rabbit genetic combinations will produce in the way of color. Sometimes the parent's genes are simple and sometimes (most often)they are not. If you are new at the breeding game, you might enjoy playing with probability calculators, which will show you potential color outcomes of any pair of rabbits mated together.

There's a new website in town, and Mamma Rabbit has such a calculator free on site. I just fooled with it for a bit and was entertained. The downside of any of these calculators (and they are included in most rabbit pedigree software programs, also) is that unless you have the parents' colors properly labeled, they are not even close. This ARBA (American Rabbit Breeder Association) rabbitry breeds show color rabbits, but some colors that pop out in litters are not showable. This is not an issue with fiber rabbits, but it does make the color names tough to settle on, when using an ARBA color list.

Color identification comes with experience, but there are some vital clues exhibited on day four of any angora's life that should not be missed. If you ever have a question about what color you have, feel free to contact me SENDING PICTURES of all sides (at least 6) of the kit and I'll send you MY guess. Then again, once the coat comes in fully, after 4-6 weeks, certain color modifications are evident (the color rings in an agouti coat and the ticking in a steel pattern, for example)and the original guess can be fine tuned.

At the end of the day, knowing the honest history of the colors in the parents, grandparents and great grandparents will be your best guide. Getting rabbits from people you trust will go a long way towards that end. Know thy breeder!

Wool Mites and Harvested Angora
Topic: Wool Mites

I had a wonderful time browsing at Cummington while waiting for the second bunny to arrive, and got a chance to really look over the wares that folks had brought. I bought some fabulous handspun French angora from ELEMENTAL DESIGNS; mohair and mohair dyed locks to play with from Twin Gate Farms; and my usual spinning batts from Spinner's Hill. I love to fiber shop and support small fiber businesses.

It was interesting to see the angora rabbits there, from bunnies too young to be sold (!) to pricey Germans with weepy eyes (!) to delightful Agouti bunnies (I do not keep or breed that color pattern, but someday I may have a few for fun). I acquired my own bunny from Charlene, and Grijsje will make an appearance on the blog this week, as will Lucinda who comes with Shelia and Jen today.

In browsing, I happened to see bags of angora spinning fiber for sale. Those of you with angora rabbits already who buy spinning fiber would do well to treat the fiber as you would a new rabbit. Quarantine the fiber for a while, then treat it for fur mites before you use it, as discussed here before. Fur mites can invade your clothing in 5 minutes when you use infected fiber, and then invade any rabbit you touch or feed in the next few hours. So, just think before you proceed. And, if you are selling fiber, it would be a courtesy to sprinkle the fiber with CARBARYL flea powder before you pack it.

Two new bunnies coming, red angoras and eye color clues
Topic: eye color

The Massachusetts Sheep and Wool Festival is this weekend, and I will spend Saturday morning there browsing, shopping and picking up two new bunnies. I have long wanted a German rabbit from Nancy Benda at The Spinning Bunny, and made connections to finally get one this spring! And Charlene Schultz has another black buck bunny for me that is related to my beloved and lost Zwart, so I will bring him back, too. It seems like 2005 is my year of LOTS of rabbits, for I have 15 bunnies on the ground; a last litter due tomorrow; and the two I have purchased. The barns will be empty no more!

So, a question about the red glow in brown eyes has surfaced. Can it mean that the color red is underneath???? Sadly, no. I had the same question back in the beginning as I was hunting for red signs in my adult stock, so I had an idea who to breed to get red bunnies. The red glow generally means there are modifying "C_c" genes letting only parts of black and yellow color shine through the coat and eyes. Sometimes I wonder if the "D_d" genes put a damper on the full expression of whatever color is in the "B_b" spot. I have not had any full "shaded" rabbits here, but I am told they, too have a red glow to their eyes in the right light. Also, chocolates (and blues I would suspect, but I don't have any!) have a red glow to their eyes in the right light. I have even had chocolate rabbits who have golden tips on their fur around their heads. The golden fur is sunburn (!).

A complete discussion of the "C_c" gene and what it does to eye color is found in an older post here

Red comes from Rufus modifiers ADDED TO a tortoiseshell or fawn pattern
A-B-C-D-ee
aaB-C-D-ee
A-bbC-D-ee
aabbC-D-ee
They are only expressed when the "no B or b showing" rule (ee) lets them shine. Rufus can be shown in degrees, and it is denoted as "+". There are five degrees in a full red rabbit, and breeding a +++ to a ++ you CAN get a +++++.
Rufus modifiers are unmistakable in a red parent, and as far as I can tell, totally masked in other colors although they can be carried along from generation to generation.

Red is always a wild card when you breed for "ee". It's always Christmas morning when I discover it in my rabbits!

Chocolate and Tortoiseshell = ?
Topic: color genetics
I am always entertained by color genetics. I used to be consumed by predicting what color bunnies would be born if I paired certain rabbits. I learned a LOT by going after RED rabbits with French and English angoras for 8 years. [The red factor has been put on a back burner while I go after HEALTH in German crosses (not as easy as I hoped)].

At any rate, it struck me last night that Sydney and Neo have created an interesting litter.

Sydney is chocolate (and I while don't have a picture of her at the ready, here is an English angora I had years ago to show the color):

Neo is tortoiseshell:

and from their gene sharing, we got
4 black rabbits and 4 white rabbits:

This is a colorful business!

So here's how it works:
The dominant genes are ABCDE.
The recessive genes are abcde.
There are few moderately dominant and modifying genes, but in this case they do not come into play.

A complete discussion of how color shows itself in a black rabbit is here on the blog:
BareHare January 2004

Neo is aaB-CcD-ee.
Sydney is aabbCcD-E-.

I know what these parents are genetically because:
1. I have bred them before and seen what color bunnies they had. Neo has never had a chocolate bunny, but both his grandmothers were chocolate.
2. I have bred them before and know there are UNDERLYING genes in the "D" and "E" positions...therefore the white bunnies posses wild cards in that department!

In fact, I was SURE Neo had a chocolate gene. And he may have. That does not mean it will come out in any litter, even though the odds were fabulous that IF he had a chocolate gene, it would pair with Sydneys' and produce some chocolate bunnies.

They had black bunnies that are:
aaBbC-D-Ee
And white bunnies that are:
aab-cc--e-

Recessives can cruise along undetected for generations and then express themselves one fine day. But the nice thing about Sydneys' bunnies is that I KNOW each white and black bunny has a recessive "b" chocolate gene from Sydney, a recessive "a" self color gene from either parent, and a recessive "e" gene from Neo. The NEXT generation from this litter will produce those recessive expressions IF I pick the right parent.

New Bunnies!
Topic: Breeding

Sydney delivered 8 healthy, fat and squeaky bunnies at 8:10 yesterday morning. She is content and eating and they are well fed and simply gorgeous. I am so totally proud of her! Just 5 weeks ago she had a disastrous first litter and was afraid of her own shadow. Now, she has tackled motherhood with a calmness and assuredness that I wonder over.

Her first pregnancy was filled with fear and she ate very little. Her second pregnancy was all about food. She ate 3x the normal ration for a rabbit and put back all her body weight, fed her developing bunnies, and then some. My husband commented that maybe it took the first loss to have her hormones kick in. What ever it was, all systems are "a go" now.

These bunnies, 4 (look to be) black (at this point) and 4 white/torte (can't tell yet!) are Taurus Sun, Cancer Rising, Libra Moon. They will be beautiful, stubborn, home loving, loyal bunnies.

We are very, very pleased with the days events!

Bunny Feet and Good Handling Habits

I love bunny feet. They are simply adorable. PLUS, if you take the time to look at feet every day, you get the wee critter used to being upside down, which makes it easier to groom/clip their bellies later on.

If you have ever seen a bigger (4 weeks) bunny nurse, they scramble under mama and flip over to reach up for the milk faucet. They have to be FAST because unless she chooses to nurse them, she will not tolerate the free lunch for long. So, flipping them over when you hold them is a familar position for this young age...just keep it going with your bunnies and your later grooming chores will be easier on both of you.
