The extent of farm-level extra-label drug use in Kenya is not well documented in spite of its important implications on food safety, human health and international trade. One hundred and thirteen farmers in Kajiado and Narok districts were interviewed between October 2005 and February 2006 using ...
First lactation 305 days milk yield (FL305DMY) records (2032) on Sahiwal cows, maintained at 3 different farms in India were analyzed to estimate the impact of direct additive genetic, maternal additive genetic and cow’s permanent environmental effects on milk yield and to compare sire model (BLU...
Micromolar calcium activated neutral protease (CAPN1) was evaluated as a candidate gene for a quantitative trait locus (QTL) on BTA29 affecting meat tenderness by characterization of nucleotide sequence variation in the gene. Single-nucleotide polymorphisms (SNP) were identified by sequencing a...
A mathematical description of the transmission dynamics of the tick-borne infection Cowdria ruminantium in commercial beef enterprises in Zimbabwe was used to consider the potential impact of a candidate vaccine to prevent heartwater. The important characteristics of the vaccine were (1) a delay ...
Many parasite species are known to show high levels of genetic diversity, yet the consequences of this diversity for host-parasite interactions are not well understood. Variation in phenotypic traits such as growth rates and the ability to form transmission stages are raw material for natural a...
In order to elucidate the mechanism of anemia in Japanese bovine theileriosis, we investigated the oxidative alteration of red blood cells (RBCs) in cattle infected with Theileria sergenti. As an index of RBC oxidation, the levels of 2',7'-dichlorofluorescin-diacetate (DCFH) oxidation and malo...
The protozoan parasite Theileria parva infects and transforms bovine lymphocytes, giving rise to a fatal lympho-proliferative condition known as East Coast fever. Although immune cattle mount strong cytolytic T. lymphocyte responses to the parasite, naive animals appear unable to respond and deve...
