The impact of utilizing the genomic relationship matrix (G) computed based on breedwise allele frequencies or different scaling factors on the accuracy of genomic prediction in cross-bred dairy cattle in smallholder systems was investigated. Data consisted of genotypes from the Illumina HD chip a...

Osmotic resistance of erythrocyte in hypotonic saline was spectrophotometrically determined in White Fulani cattle, West African Dwarf sheep and goats.Osmotic fragility was found to be highest in goat with maximum resistance occuring at 0.75% and 0.55% sodium chloride solutions. It was lowest in ...

Three breeds of cattle, the White Fulani (zebu breed), German Brown and Holstein (European breeds), of the same age, kept under identical conditions were studied to delineate differences in some body fluid charateristics. Data on comparative values of blood contituents, serum constituents and bod...

From ancient times people have depended on domesticated animals and the crops needed to feed them. But modern pressures are destroying ancient breeds whose irreplaceable genes are a unique resource in an uncertain world. These three films (length about 12 minutes) outlines the issues and suggest ...

A deltamethrin `pour-on' insecticide was applied monthly to over 2000 cattle exposed to a high challenge of drug-resistant trypanosomes and high tsetse re-invasion pressure in the Ghibe valley, south-west Ethiopia. Blood samples were taken monthly from an average of 760 cattle for determination o...
