The Pomeranian goose , also known as the Rügen goose , is a very old, large breed of goose .
history
The Pomeranian geese were already at the beginning of the 14th century by Prince Witzlaw III. sung about by Rügen , the chronicler Thomas Kantzow also wrote the "Rügen geese" in his Pomerania . They have been kept for several centuries in Pomerania , especially on Rügen and in the Uckermark , a region in northeastern Brandenburg , both on large estates and on smaller farms . The start of a scheduled breeding can be determined around 1300. The Pomeranian goose is younger than the Emden goose , which is said to have been involved in the breeding of the Pomeranian goose.
The breed as such was recognized in 1912 . Today it is bred all over Germany. With its three colors, the Pomeranian goose is now one of the most popular goose breeds in Germany.
features
The Pomeranian goose is a heavy goose, it attaches a simple belly dewlap . Your body should be egg-shaped with broad shoulders and a horizontal, slightly erect body. It has a horizontal tail with relatively short feathers, which should all be colored through. Overall, the plumage looks tight and close-fitting. There are three colors: gray, white and gray-checkered. The grays should show evenly dark gray, not brown-gray feathers. The whites have shown the best form animals at exhibitions in recent years, but they were seen less and less. The gray piebalds, also regarded as the royal breed of geese, show a high failure rate due to the breeding.
The pomeranian geese are calm animals. They also have very good breeding and maternal behavior. This means that the geese should not lay more than 15 eggs, as in this case they cannot warm all the eggs evenly under themselves during the brood. In the case of natural breeding, the breeding period is approx. 28 days, whereas artificial breeding can last as long as 30–31 days. Basically, the best rearing successes are achieved with natural brood.
use
The Pomeranian goose is a good farm goose with a very good meat set. These geese reach a weight of around 8 kg. But even without fattening, specimens with a slaughter weight of 7 to 9 kg were observed. As with all geese, the feather quality is very good. It should be noted that only dry-plucked feathers are used for your own beds, as feathers that have been washed have largely lost their natural fat and therefore do not have the desired warming effect.
Color inheritance
The characteristic of color expression in the Pomeranian Goose is a quantitative characteristic, that is, it is influenced by several genetic locations at the same time. To be more precise, there are three gene locations: 1. The color formation factor C , which is responsible for the expression of the color present in each case. In its recessive form c, it causes the expression of the color white in homozygosity. 2. The factor for the full expression Sp of the existing color. As a recessive allele it causes the incomplete expression of the color, i.e. the so-called spotting . 3. The factor for the lightening of the plumage Sd , which is bound to the sex chromosome and thus only occurs once in females. In all colored Pomeranian geese it is present as a recessive allele sd .
The above considerations result in the following genotypes in purebred animals, whereby it must always be taken into account that all female birds, as well as male mammals, only have one sex chromosome.

White Pomeranian Goose: Ganter: cc- - - - or Goose: cc - - - -
Explanation: White geese have the allele for no color development cc , i.e. it does not matter which combination the alleles for full expression and pigment dilution are present, since no color can be developed anyway. This is a typical case of epistasia : A gene can influence the expression of one or more genes.
In the case of gray geese, the allele for color expression is present, that is, they are colored animals. Now let's look at the color expression: Full color expression and no pigment dilution lead to a completely gray animal.
The allele for color expression is also present in piebald geese, that is, they are colored animals, but they have the allele for incomplete color expression, i.e. the piebald, and the allele for no pigment dilution.
From this, the assessment of the following crossing attempts can be derived: (considered regardless of gender) gray (CC SpSp sdsd) times piebald (CC spsp sdsd) results in the following genotype in F1: CC Spsp sdsd, i.e. a goose is gray, whereby the gene for the full color expression is heterozygous and mixed. If you now cross F1 back with the recessive parent, i.e. a piebald goose, you get in a ratio of 1: 1 gray mixed- breed animals with the genotype CC Spsp sdsd and piebald pure-breed animals with the genotype CC spsp sdsd. Crossing with white geese, on the other hand, is more problematic, since the genes for full color expression (and pigment thinning ) cannot be shown and therefore the genotype cannot be assessed. However, when crossing white with cc and colored geese with CC , colored animals with Cc should always appear. Whether these animals are piebald or completely gray, of course, depends on the one hand on the colored parent animal (is it gray or piebald) and on the other hand on the genotype of the white animal, since the allele for dye prevention does not allow the markings that may be present to develop. In the presence of Spsp or SpSp , gray animals and spsp piebalds arise .
