Previous studies have shown that the serum enzyme levels of overfed geese are similar to those observed in humans with non-alcoholic fatty liver disease, suggesting that the unique fat storage and metabolic characteristics of goose liver may be an important reference for the study of lipid metabolism disorders in humans. In agricultural production, this particular phenotype is manifested following short-term overfeeding (approximately 2 to 3 weeks), resulting in fatty livers and a 5- to 10-fold increase in liver size. Second, compared to other birds, the goose liver has a high capacity for fat accumulation, although geese do not normally develop liver fibrosis or necrosis. First, they exhibit a low susceptibility to certain avian viruses, showing little or no symptoms while still acting as a virus carrier, making them a natural repository for certain avian viruses. Compared with other terrestrial poultry (for example, chicken and turkey), waterfowl, such as ducks and geese possess uniquely favorable economic traits. Geese play an important role in agricultural economics, with China producing the vast majority (94%) of the approximately 2.23 million tons of goose meat consumed worldwide annually, followed by Egypt, Hungary, and Poland. The findings in this study are useful not only for genetic breeding programs, but also for studying lipid metabolism disorders. This is the first report describing the complete goose genome sequence and contributes to genomic resources available for studying aquatic birds. The results of this study show that deletion of the goose lep gene might be the result of positive selection, thus allowing the liver to adopt energy storage mechanisms for long-distance migration. In addition, analysis of transcriptome data further reveals a potential molecular mechanism involved in the susceptibility of geese to fatty liver disease and its associated symptoms, including high levels of unsaturated fatty acids and low levels of cholesterol. Comparative genomics indicate that significant differences occur between the goose genome and that of other terrestrial bird species, particularly regarding major histocompatibility complex, Myxovirus resistance, Retinoic acid-inducible gene I, and other genes related to disease resistance in geese. ResultsĪ draft sequence of the whole-goose genome was obtained by shotgun sequencing, and 16,150 protein-coding genes were predicted. Here, we sequence and analyze the whole-genome sequence of an economically important goose breed in China and compare it with that of terrestrial bird species. Geese are capable of rapid growth, disease resistance, and high liver lipid storage capacity, and can be easily fed coarse fodder. On lots 10,000 square feet or larger, more than four hives may be kept, provided there is an additional lot area of 2,500 square feet for each hive.Geese were domesticated over 6,000 years ago, making them one of the first domesticated poultry. Honeybeesįour beehives or less are allowed on any lot. Racing, homing, or exhibition (fancy) pigeons are allowed on any lot that is 10,000 square feet or more. Roosters are not permitted, except with an agricultural use. Only fowl two months or older are counted in the ratio.
They shall not exceed the ratio of one bird unit per one acre, with a bird unit defined as: Domestic Fowlįowl, such as chickens, ducks, turkeys, and geese, may only be kept on lots that are two acres or greater. In addition, combinations of animals are allowed, provided that the ratio of one animal unit per one acre is followed. Only horses six months or older and cattle, sheep, goats, and swine one year or older are counted in the ratio. Horses shall include ponies, mules, burros and donkeys. They only may be kept on lots that are two acres or greater and shall not exceed the ratio of one animal unit per one acre.

Animals considered wild or exotic under Chapter 41.1 of the County Code are not permitted. These regulations can be modified with approval of a special permit by the Board of Zoning Appeals. Also, location regulations apply to barns and structures that shelter animals. The type and number of animals that may be kept on a property depend on the size of the lot. The Zoning Ordinance and Chapter 41.1 of the County Code allow residents to keep certain animals, such as cats, dogs and hamsters, on their property for personal enjoyment and non-commercial purposes.
