In Côte d’Ivoire, the local hen breeding constitutes nearly 70% of national poultry
livestock in Côte d’Ivoire. Local hens of Côte d’Ivoire in general, are less known by
scientific community because it is almost fewer characterized. In this context, it is
necessary to work with the aim of improving local hens’ productivity in order to
contribute at food self-sufficiency. Therefore, the present study was carried out to
assess the shelf life and placement of the egg before brooding.240 eggs from 82 local
hens aged 36 weeks were divided in 6 batches of 40 eggs each. At first 3 batches were
stored during 3 days, 5 days and 10 days respectively for batch 1, batch 2 and batch 3.
Secondarily, the 3 others batches were stored during 5 days using 3 breeding positions
namely vertical position with small end up, vertical position with the small end down
and the horizontal position. Influences of storage duration on eggs weight and position
of eggs on hatchability characteristics were evaluated.
The study showed that the positioning of the eggs significantly influenced hatchability
and the horizontal storage position gave the best results compared to the two other
positions. The average fertility of the local eggs recorded in this study showed out that
long-term stored eggs presented lower hatching average. For the local hens, a storage
of 5 days maximum before incubation of the eggs is advisable.
The positioning and storage time significantly influenced the weight and hatchability
of local eggs.
