Handling and General Care

Handling and General Care

Rabbits can be messy, so you’ll need to clean your pet’s cage once or twice weekly. Put your rabbit in a safe room or alternate cage as you sweep out the cage and scrub the floor with warm, soapy water.

Pick up your rabbit by supporting his forequarters with one hand and his hindquarters with the other—failure to do so can result in spinal injuries to the rabbit. Never pick up a rabbit by his ears; this can cause very serious injury.

Brush your rabbit regularly with a soft brush to remove excess hair and keep his coat in good condition. Brush from the back of the head down to the tail. Ask your veterinarian how to clip your pet’s nails.

Like other domestic rabbits, dwarf rabbits have a sensitive digestive system that is less hardy than their wild rabbit cousins. Leafy vegetables such as lettuces, cabbages, and greens (collard greens, mustard greens, beet greens, spinach, and kale) are crucial. Young rabbits, up until about eight weeks of age, should not be given vegetables due to the lack of development in their digestive system. Adults can be fed safe veggies daily, and should be given four heaping cups of varied vegetables (three or more) per five pounds of rabbit. In addition, sudden changes to a dwarf rabbit's diet can cause digestive problems, but it generally only lasts a few days and usually causes no real harm/lasting damage.

A very important aspect of rabbit care is proper diet. Many owners unintentionally fail at this point and that often spells disaster for their pet. Netherland Dwarfs have a digestive system even more sensitive than most breeds. The best diet consists of fresh, good quality rabbit pellets fed in limited amounts. It is crucial that the pellets be fresh and stored for no longer than eight weeks, do not use pellets which are moldy or have been contaminated. As pellets age they lose important nutrients, and a rabbit’s system will become susceptible to disease. The owner should also check the label for the percentages of protein, fiber, and fat. The National Research Council lists minimum rabbit nutrient requirements for a maintenance diet as 14% crude fiber, 2% fat, and 12% protein. It is best to feed a pellet that is higher in fiber (18-20%) and lower in protein (14-15%) and fat (2-3%) to a pet rabbit. Once you find a good brand, stick with it; frequent changes in diet can cause digestive problems. If you need to change brands, be sure to mix the new feed in with the old and increase the amount of new to old over a week's time so the rabbit can adjust.

Netherland Dwarfs generally don't require much feed. A small handful each day is usually enough, but it is important to adjust for each individual to avoid malnourishment/obesity. It is also important not to overfeed a Netherland Dwarf. Hay, however, can be given in unlimited amounts. A traditional ramekin dish full of complementary food and free access to water is always required.

Chromosomes and Genes

Chromosomes are strings of DNA. They act as blueprints or programs by which an organism builds itself. A chromosome is made up of individual points (or loci) called genes. An individual gene determines either the appearance or function of a body part. This gene may act alone or, usually, in concert with other genes to determine a particular appearance or function.

A chromosome string is linked together with one other chromosome string of the same type having the same gene locations. Thus, chromosomes and the genes on them occur in pairs in most of the cells of the body. There are 22 different chromosome pairs existing in each cell of the rabbit except the sex cells and red blood cells. Each chromosome pair controls different functions. For instance, the X and Y chromosomes determine sexual characteristics.

The same location on each chromosome of the pair controls the same characteristic. There are thus two genes involved - one on each chromosome at the same location. A particular gene location may allow only one type of gene to be present there; whereas, another location may allow different types of genes to occupy it. Those locations that allow only one type of gene on both chromosomes do so because any other type would cause either deleterious or fatal effects. An example of this would be the genes that control the shape of the teeth. If any other than the expected gene type is present at this location, the teeth would not grow in right, which could cause starvation.

Some locations allow different types of genes to stay there, causing different expressions of the same characteristic without deleterious effects. For instance, a hair color gene location may allow 2 genes of different types to occupy that location. One type of gene may be the gene that produces black hair, the other brown. Each chromosome may house either the black or the brown gene.

Some of the genes match their counterparts on the other chromosome exactly and some do not. When two genes match, such as, two black genes, this is called a homozygous pairing (homo- meaning the same). When the genes are not the same, such as one black and one brown gene, this is called heterozygous pairing (hetero- meaning different). Another name for heterozygous is hybrid. You've heard this term used in such common language as hybrid corn or hybrid tomatoes. These vegetables have one type of gene on one of the chromosomes, and a different gene on its companion chromosome.

When we speak of a gene location, we're really talking about two points - one on chromosome A and one on its companion chromosome B. Since there are two chromosomes involved, there are two genes involved - one from each chromosome. The points on each chromosome match up perfectly with the points on its companion chromosome. Thus, a location is made up of two genes.

Dominant and Recessive Genes

When two different genes occupy the same location, one of the genes expresses itself in the characteristic and the other either doesn't or does so to a lesser extent, modifying the effects of the other gene. When one gene expresses itself more than the other, it is called the dominant gene. The other gene is called the recessive gene. When the dominant gene expresses itself completely, to the exclusion of the recessive gene, this is calledcomplete dominance. Most dominant genes express themselves completely. When the recessive gene modifies the expression of the dominant gene in some way, the relationship of the dominant gene to the recesive gene is called incomplete dominance.

When a buck produces sperm or a doe produces eggs (both of these cell types are called gametes), the chromosome pairs in the cells that create these gametes divide, putting one chromosome of each type into the gamete. When the doe's egg is fertilized by the buck's sperm, the chromosome from the sperm unites with the same chromosome type in the egg and the chromosome pairing is once again restored. Whatever genes that came from the buck are now matched up with the genes of the doe. The expression of these genes in the resulting offspring depends on their dominance and how the other genes relate to each other.

The Mathematics of Genetics

Genetic determination is based on the law of probability. Without getting into the complicated aspects of gene mapping distance and linkage, I will present a simple concept of how you can figure what your offspring will look like.

It is common to represent a dominant gene by a capital letter and its recessive counterpart(s) as uncapitalized. Let's take the black/brown color location. This location is called B. The black gene, which is completely dominant, is represented as 'B'. The only known recessive gene that can occupy this location is brown, represented as 'b'. Since a location has two genes, there are 4 possibilities at this location: BB, bb, Bb, bB. Since black is completely dominant, if you have a rabbit that has at least one B at this location, the rabbit will have black in its fur. Thus, rabbits having the combination of genes: BB, Bb, or bB will have black in its fur. Rabbits having the combination of bb will have brown.

Note that it usually requires both recessive genes (bb) at a location for that set of genes to express itself. When the dominant gene is not completely dominant, the recessive gene will modify the expression of the dominant gene in some way. As far as the black/brown location, the black gene is completely dominant and will always express itself, if present, to the exclusion of the brown gene.

There are other genes that work with the B gene to determine that actual color of the rabbit. We will assume in this discussion that the other genes are set up to produce a solid black or a solid brown rabbit.

Let's take a black rabbit and mate it with another black rabbit. What are the possible offspring? We know that a black rabbit has at least one B gene. If we don't know for sure the other gene is B or b, we can represent that other gene as '_' (unknown). We can thus represent both genes in the black rabbit as: B_.

When it comes to dominant genes, we usually cannot know for absolute certainty that the other gene of the pair is also the same dominant gene. The exception to this is when the recessive gene acts with the dominant gene to produce a certain known characteristic, such as English spotting.

Getting back to our example, we have one black rabbit whose black/brown gene location is represented as B_. Let's assume the other black rabbit we are mating it to is also B_. Breeding the rabbits [B_ x B_], we combine the left gene of #1 with the left gene of #2 , giving BB - a black rabbit. Then we combine the left gene of #1 with the right gene of #2, giving B_ - another black rabbit. Then we combine the right gene of #1 with the left gene of #2, giving _B - another black rabbit. Then we combine the right gene of #1 with the right gene of #2, giving _ _ -unknown. We thus have:

B_ x B_ = (BB, B_, _B, _ _)Let's fill in the blanks. If one of the rabbits had both black genes (BB) all of the litter would be black, without exception, even if the other rabbit had one brown gene. It wouldn't matter how many times you bred these two rabbits together, you would always have black offspring.

BB x B_ = (BB, B_, BB, B_)Remember, if at least one black gene is present, the rabbit will be black.
Only if both rabbits had one brown gene would a brown rabbit (bb) be produced. It may take two or more breedings to see a brown rabbit because the probability is only 25%.

Bb x Bb = (BB, Bb, bB, bb)

How can we test to see if one of the black rabbits has a brown gene in it? Simply mate the black rabbit with a brown rabbit. If you get any offspring that are brown, you know for a fact that the black rabbit has a brown gene in it. The probability is that you should get about 50% brown offspring. Here is the formula:

B_ x bb = (Bb, Bb, _b, _b)Filling the blanks, if the unknown gene is B, all of the litter will be black. If the unknown gene is b, about half should be brown. Since we are talking about probability here, the litter could still be all black or could be all brown. If you get an all black litter, you may still have to breed one or more times to see if at least one brown rabbit is produced. If a brown rabbit is produced, you know for a certainty that the black rabbit has one black gene and one brown gene. If you get all black rabbits from matings all the time, it is probable, but not certain, that the black rabbit has both of its genes black.

In summary, to test for the presence of a recessive gene when only the dominant is showing, mate it with a rabbit that shows the recessive gene. If at least one of the offspring shows that recessive gene, you know positively that the rabbit you were testing has the recessive gene along with the dominant gene. If you do not get any offspring showing the recessive trait after several litters, the odds are that the rabbit in question does not have the recessive gene (but you can never know with absolute certainty). Remember that about half of the offspring should show the recessive trait. But if no rabbits in the litter expresses the recessive gene, we're still talking probabilities here. The failure of the recessive gene showing up in all of the litters does not prove the tested rabbit does not have the recessive gene, just that the probability of its having it is low. But if any rabbits in the litter show the recessive gene, it is proof positive that the tested rabbit has the recessive gene along with the dominant.

Hair Color

Hair color in rabbits is controlled by genes at several locations on the chromosomes. These genes act in conjunction with each other to produce quite a variety of different colors and patterns. Hair texture and length is controlled at other locations.

In this section, I intend to touch on only some of the basic color genes and their combinations. For a larger list and a thorough discussion, refer to the book, The ABC's of Rabbit Coat Colors, mentioned before.

The basic color genes in the rabbit are A through E, En, Du, Si, V, and W. Other genes act as color modifiers controlling the intensity of certain colors or patterns. They include the rufus modifiers, the plus/minus (blanket/spot) modifiers, and the color intensifiers. These modifiers are not single genes, but multiple ones that pool their effects.

A rabbit has two possible pigments that can be expressed in its hair - dark brown and yellow. The absence of both pigments results in white fur. All of the colors possible in rabbit fur are simply combinations of these pigments or lack thereof. The expression can appear on the same or different hairs, in certain patterns, and in different intensities.

In general, rabbits that have long hair, such as Angoras, have diluted color expression. Rabbits that have short hair, such as Rex, have more intense color expression. This is because, given the same genetic background, the number of pigment granules in the hair is the same. In long hair the pigment granules are spread further apart from each other, giving a pastel color. In short hair, the pigment granules are packed more closely together, making a more intense color.

Rabbits in the wild have a brownish fur color called agouti. Looking closely at this fur, you can see that it is made up of 3 to 5 bands of color. The hair closest to its skin is gray. This is followed by yellow, followed by black on the tips of the fur. These rabbits also have white bellies. This agouti pattern is found in some domestic rabbits today. They call this color chestnut. There are several variations of this agouti pattern in domestic rabbits. These variations are caused by the other genes and modifiers working together.

We can classify the color genes in two groups. First, the color pattern genes. These genes determine which pattern will be expressed: agouti, tan, or no pattern. All of the other genes are the color genes. These genes determine the placement and intensity of the color pigments on the hair.

The following table represents a list of the known genes, how they affect hair color, and some examples of rabbits having these genes. These genes are listed in the order of dominance within each group. Taking all of the genes together, there are thousands of color patterns possible. The American Rabbit Breeders Association has limited the number of color patterns it will accept for each breed in their Standard of Perfection..
