Fertility and Hatchability in Goose Eggs: A Review

مطالعه اثرات شستشو، مدت زمان و دمای نگهداری بر خصوصیات جوجه کشی تخم غازهای بومی استان آذربایجان شرقی

     The aim of this study was to investigate the effects of washing, storage time and storage temperature on hatchability and post- hatch growth of East Azarbaijan goose eggs. A total of 144 clean goose eggs were randomly selected from Malekan goose research station, East Azarbaijan and were asigned randomly for each treatment. There were 12 treatments in a factorial arrangement 2×3×2 based on...

Fertility and Hatchability of Pekin and Muscovy Duck Eggs and Performance of Their Ducklings

Five hundred ten duck eggs of Pekin and each of Muscovy duck eggs were incubated to determine fertility and hatchability. The eggs were cleaned and stored at 18-21oC for 6 days prior to setting in the incubator. The eggs were incubated in a forced-draft electric incubator and the hatching performances were recorded. Ninety Pekin and ninety Muscovy day-old ducklings were randomly selected from t...

The goose that lays the golden eggs.

The effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs.

An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...

Ecological and Social Factors Affecting Hatchability of Eggs

--Hatchability, defined as the proportion of eggs surviving to the end of incubation that hatch, varies among populations of birds. Here, I examine the effects of a variety of variables on hatchability in a comparative analysis of 155 studies of 113 species. Of the ecological nd geographical variables considered, latitude, diet, and nest type explain a significant amount of the variance in hatc...
