Evaluation of growth performance and feed efficiency in reciprocal crosses of Fayoumi with three exotic chicken breeds

ABSTRACT Reciprocal crosses of Fayoumi with Koekoek, Sasso, and White Leghorn chickens and the purebreds were evaluated for growth and feed efficiency traits. Birds were weighed individually at hatch and every four weeks to 20 weeks, and body weight gain was the difference between consecutive records. Feed conversion ratio was the ratio of feed consumed to weight gained by the birds. Results revealed significant differences among the genotypes in those traits. Sasso outperformed all other genotypes throughout the study period. Reciprocal crosses of Fayoumi and Sasso performed better than the remaining seven genotypes, with Koekoek and reciprocals of Fayoumi and Koekoek showing intermediate performance, but Fayoumi and White Leghorn and reciprocals involving them performed the least. In most instances, reciprocals of Fayoumi with Koekoek and White Leghorn outperformed both of their parents. Therefore, these genotypes could be used in any crossbreeding system to exploit the heterotic effects that existed in them.

期刊介绍： Acta Agriculturæ Scandinavica, Section A – Animal Science publishes results of original research in animal science and their applications related to the following topics: -Animal breeding and genetics -Molecular genetics -Animal physiology and reproduction -Nutrition and feeding -Animal behaviour and welfare -General animal husbandry and systems of production, including economic and technical aspects -Hygiene and quality of animal products In addition to original articles, covering basic as well as applied subjects, the journal features review articles and short communications. Acta Agriculturæ Scandinavica, Section A – Animal Science forms part of a trilogy of titles published on behalf of the Nordic Association of Agricultural Scientists (NJF). The series also includes Section B - Soil & Plant Science and the recently launched Section C - Food Economics . Acta Agriculturae Scandinavica A, B and C are available to purchase as a combined subscription. This provides access to all three journals in the series, and is available to institutional subscribers only. For full pricing information, please view the Taylor & Francis Journals Price List here.
