Animal health and genetics—Issues and controversies for ILRI research por International Livestock Research Institute

“…We need to better match genetics with conventional phenotyping.7) An important role for ILRI concerns ethics: We need to generate evidence, communicate evidence effectively, facilitate its appropriate use. 8) Fertility management and sex-fixing of cattle (through mass insemination) has the potential in pastoral areas recovering from droughts to accelerate herd recovery rates. …”

Economic values for production and functional traits of Small East African goat using profit functions por Mbuku, S., Kosgey, I.S., Okeyo Mwai, Ally, Kahi, A.

“…The economic values for production and functional traits, except RFI, were positive, which implies that genetic improvement of these traits would have a positive effect on the profitability in the pastoral production systems. The application of an Arrow-Pratt coefficient of absolute risk aversion (λ) at the level of 0.02 resulted in a decrease on the estimated economic values, implying that livestock keepers who were risk averse were willing to accept lower expected returns. …”

Population regulation of African buffalo in the Mara–Serengeti ecosystem por Dublin, H.T., Ogutu, Joseph O.

“…Conclusions: Recovery of buffalo numbers to pre-drought levels took 8–9 years after the 1984–85 drought but was much slower, with buffaloes numbering merely 36% of their 1993 population (12 895 animals) 18 years after the 1993–94 drought despite intermittent periods of high rainfall, probably due to demographic and/or reproductive factors, heightened competition with livestock, land use changes in the adjoining pastoral ranches, lion predation and recurrent severe droughts. …”
