| Abstract |
The present study was carried out at six villages in El-Mahmodia city, Beheira Governorate through season 2004/2005. A total number of 503 four weeks old local goslings (191 males and 312 females) were kept and grown by six farmers under the prevailing local conditions. Goslings were shank banded, weighed on individual basis and housed in simple houses. Birds were exposed to natural daylight, fed green forage and rice on' the pasture and swimming in water ducts. Nature mating was practiced during the period from November to the end of May with a male: female ratio ranged from 1:3 to 1:4. A total number of845 eggs were collected and weighed for the nearest gram and 338 eggs were broken to study and measure the egg quality traits as a percentage of egg weight. Natural hatching was used and about 12 hatches were taken per each farm.
The main results could be summarized as follows:
1- Body weight for both sexes of goslings raised in winter had significantly higher means than those of the fall and spring seasons at 4, 8, 12, 16, 20, 24, 28 and 32 weeks of age.
2-The overall means of mortality percentage in fall, winter and spring seasons from 4-32 weeks of age were 16.98, 11.76 and 16.98% for males and 14.86, 10.42 and 13. 13% for females, respectively.
3-Geese raised during winter season had higher significant fertility and hatchability percentages (84.31 and 73.38%) than those raised in fall season (76.96 and 64.39%).
4-The age at 50% egg production ranged between 36.78 and 41.26 weeks and the gooslings raised in spring had a smaller. age (37.57 weeks) than those of goslings raised in winter (38. 71weeks) and fall (40.15 weeks).
5- The average number of eggs laid / geese/week were 1.33, 1.74 and 1.44 egg with the average egg weight of 134.60, 144.34 and 138.66 g. in fall, winter and spring seasons, respectively. These values for geese raised in winter exelled those raised in fall and spring.
6- Shell and yolk weight as a percentage of egg weight and shell thickness (mm) were higher for the winter season than the other two seasons, while the reverse was recorded for albumin.
. Generally, geese raised in winter season recorded superior values than those of spring and fall for all studied traits except age at 50% egg production which was the best for geese raised in spring season.
