Canada geese leave the winter grounds more quickly than the summer grounds. Elevated thyroid hormones, such as T 3 and T 4, have been measured in geese just after a big migration. This is believed because of the long days of flying in migration the thyroid gland sends out more T 4 which help the body cope
Geese have also been strongly selected for fecundity, with females laying up to 500 eggs per year, compared to 5–12 eggs for a wild goose. [3] [5] As most domestic geese display little sexual dimorphism, sexing is based primarily on physical characteristics and behaviour. Males are typically taller and larger than females, and have longer ...
The word "goose" is a direct descendant of Proto-Indo-European *ǵʰh₂éns.In Germanic languages, the root gave Old English gōs with the plural gēs and gandra (becoming Modern English goose, geese, gander, respectively), West Frisian goes, gies and guoske, Dutch: gans, ganzen, ganzerik, New High German Gans, Gänse, and Ganter, and Old Norse gás and gæslingr, whence English gosling.
Roman geese can live up to 25 years and lay between 25 and 35 eggs per year. An egg takes 28 to 30 days for incubation. [2] If you continuously take their eggs they will lay more than the average amount. [2] These geese will begin to lay early spring. During this time the head gander will become aggressive.
The species usually lays 4–6 eggs, but it can lay anywhere from 2 to 8; eggs are often laid in the nests of other emperor geese families. [14] Eggs measure 7.86 centimetres (3.09 in) by 5.21 centimetres (2.05 in) on average, with an elliptical shape and a smooth shell.
The geese were bred progressively for 5 years and by 1954, there were 16 breeding pens each with 1 gander and 5 females. [15] All the geese were trap-nested 7 days a week for the duration of the laying season. [13] [15] After 3 years of selection, the average egg production increased from 14 to 28. [13]
On average, domestic rabbits can live to be between 8 and 12 years old, says Blue Cross, a British animal welfare nonprofit. The oldest recorded domestic rabbit lived to be 18 years and 10 months ...
The eggs are creamy-white at first but soon become stained, and average 85 by 58 millimetres (3 + 3 ⁄ 8 by 2 + 5 ⁄ 16 in). They are mostly laid on successive days and incubation starts after the last one is laid. The female does the incubation, which lasts about twenty-eight days, while the male remains on guard somewhere near.
