Comparison of the Egg Characteristics of Different Sudanese Indigenous Chicken Types

Abstract: 
Three local types of Sudanese indigenous fowls, large Baladi (LB), Bare-neck (BN) and Betwil (BT) were characterised for maturity live weight and egg characteristics. The BN average live weight (1547.2±274.5 gm) was heavier than either LB (1494.4±349.8 gm) or BT (1198.3±257.5 gm). The BT average live weight was significantly (P<0.05) lighter than those of other two types. The weekly hen-day egg production means were 3.7, 3.2 and 3.9 for (BN), (BT) and (LB) respectively, while the corresponding hen-housed egg production means were 3.3, 2.7 and 3.4. The rate of egg production during the laying period (36 weeks) was 47.14, 38.57 and 48.57 for BN, BT and LB respectively. There were significant differences (P<0.05) in average egg-shell thickness among local types. The means of egg-shell thickness for BT and BN, 36.2±4.2 and 36.2±4.0ì respectively were similar and both significantly thicker than that of LB, 34.3±3.6ì.
Trois types locaux de volailles indigènes soudanaises, Baladi large (LB), cou-nu (NE) et Betwil (BT) ont été caractérisés en fonction de la charge utile de maturité et des caractéristiques des oeufs. La charge utile moyenne des cou-nu (1547,2 ± 274,5 g) était plus grande que celle des Baladi larges (1494,4 ± 349,8 g) et celle des BT (1198,3 ± 257,5 g). La charge utile moyenne des BT était significativement (P <0,05) plus légère que celles de deux autres types. Les moyennes hebdomadaires de production des oeufs des poules errantes étaient respectivement de 3,7, 3,2 et 3,9 pour les cou-nu, les BT et les Baladi larges, tandis que les moyennes correspondantes de production desoeufs des poules logées au poulailler étaient de 3,3 ; 2,7 et 3,4. Le taux de production des oeufs durant la période de ponte (36 semaines) était respectivement 47,14; 38,57 et 48,57 pour les cou-nu, les BT et les Baladi larges. Il y avait des différences significatives (P <0,05) dans l’épaisseur moyenne des coquilles des oeufs parmi les types locaux. Les moyennes de l’épaisseur des coquilles des oeufs des BT et des cou-nu, 36,2 ± 4,2 et 36,2 ± 4.0i respectivement, sont semblables et aussi sensiblement plus grandes que celle des Baladi larges, 34,3 ± 3.6i.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Enhancing Livestock Productivity
