Abstract: Indigenous breeds adapt and survive in often challenging environments and diverse agroecological areas representing an important genetic resource for livelihood of their owners and the national economy at large. Therefore, there is a need to improve the productivity of indigenous animals through developing sustainable breeding programs so as to enhance their competitive advantage in the face of crossbreeding threats. The current study was performed in Kafta Humera district of Tigra...

Abstract: The study was evaluated comparative growth and age at first lay for Fayoumi and White Leghorn and their F1 crosses from day old to age at first egg. For this, a total of 176 chickens from each genotype as foundation stocks were randomly selected and naturally crossbred to obtain pure Fayoumi, White leghorn and their crosses. A total of 1000 eggs collected and incubated on the 7th day of post oviposition. Among hatched, a total of 150 chicks selected from each genotype for subsequen...
Abstract: The study was conducted to phenotypically characterize and assess husbandry and breeding practices of indigenous goat population in Tach Gayint and Ebinat districts of South Gondar Zone.
