Response of Nigerian indigenous (local) and broiler chickens to experimental Eimeria infections was investigated by measures of clinical signs, packed cell volume (PCV), body weights (BW), feed consumption, faecal oocyst counts (oocyst per gram), and microscopic intestinal lesions. Three-week-old chickens of each breed received single pulse infections with 2500, 5000, and 100.000 sporulated Eim...

Population structure and relationship information among goats is critical for genetic improvement, utilization, conservation. This study explored population level of introgression four goat breeds in Kenya: the indigenous Galla (n = 12) three imported breeds, Alpine 29), Toggenburg 31), Saanen 24). Genetic diversity was analyzed using indices (polymorphic SNPs, mean allele frequency, observed e...
