BACKGROUND More than 90 percent of cattle in Tanzania belong to the indigenous Tanzania Short Horn Zebu (TSZ) population which has been classified into 12 strains based on historical evidence, morphological characteristics, and geographic distribution. However, specific genetic information of each TSZ population has been lacking and has caused difficulties in designing programs such as selectio...

Herd dynamics of Boran Pastoralists Contemporary policy debates are rife with discussions of “poverty traps” which describe structural features of the state of poverty that cause it to persist. Different factors may give rise to different types of poverty traps: there may be groups within a population for whom there exists a unique equilibrium associated with persistent poverty and others who f...

A study was designed to examine the effect of infection with Trypanosoma vivax KETRI 2501 on the maintenance of pregnancy and postpartum return to reproductive function in susceptible Galana (n = 6) and trypano-tolerant Orma Boran (n = 6) heifers during the third trimester of pregnancy. Of the 12 study animals, 3 Galana and 3 Orma Boran heifers served as controls. One of 3 Galana heifers calved...

Trypanosomosis, or sleeping sickness, is a major disease constraint on livestock productivity in sub-Saharan Africa. To identify quantitative trait loci (QTL) controlling resistance to trypanosomosis in cattle, an experimental cross was made between trypanotolerant African N'Dama (Bos taurus) and trypanosusceptible improved Kenya Boran (Bos indicus) cattle. Sixteen phenotypic traits were define...

A standard radioactive chromium (51Cr) release assay was used to assess the in vitro phagocytosis and lysis of bovine erythrocytes by cultured splenic, bone marrow and peripheral blood monocyte-derived (PBM) macrophages isolated from healthy and Trypanosoma congolense and T. vivax-infected cattle of the Boran and N'Dama breeds. Recombinant cytokines (rHuTNF-alpha and rBolFN-gamma) and non-acid-...

the study was carried out at agarfa atvet college dairy farm to evaluate the reproductive performance of holstein friesian× arsi and holstein friesian ×boran cattle. for the study, records compiled from 1983 to 2012 at the agarfa dairy farm were used as original data. the effects of breed, bloodlines, season and parity on the reproductive traits were evaluated. data were analyzed using the gene...

Die Bor-Stickstoff-Bindung in Aminoboranen R3_KB(NR2)« besitzt eine Bindungsordnung > 1 [2], die nach schwingungsspektroskopischen [3] und PE-spektroskopischen [2 b] Studien mit steigendem n abnimmt. Borund Stickstoffatome sind als sp2hybridisiert anzusehen, da beide Atomarten von je drei Nachbaratomen planar umgeben werden. Maximale Überlappung ihrer pz-Orbitale und damit optimale TI-Bindung w...
