Some notes on the performance of Sudan Nubian and exotic goats in Sudan

Abstract

In 1976 three exotic pure breeds Sannen, Toggenburg and 
Anglo-Nubian were imported in the Sudan for improving milk and meat 
production through crossbreeding with Local Nubian goat and 
multiplication of the pure breeds. Some performance studies on the 
exotic goat in Sudan were reported by Sulieman and El Shafie (1984) 
and Khalaffalla and El Shafie (1988) In these notes the lactation 
length, lactation milk yield and kidding interval of the exotic breeds and 
indigenous goat were reported. 
Data taken from the records of the goat kept at Kuku research station 
for the period 1976 to 1979 were used in the study. Each breed was 
kept into a separate well shaded pen and all animals were fed ad lib-on 
the same diet (green forages and a concentrate mixture composed of 
25% cotton seed cake, 25% wheat-bran and 50% sorghum grains). 
Water and salt-licks were available all the time. For accurate 
measurment of the lactation milk yield, kids were separated from the 
does one week after birth (i.e. after consuming all their colostrum) and 
were artificially reared.
