Environmental and food security implications of livestock abortions and calf mortality: a case study in Kenya and Tanzania by Gurmu, Endale B., Bronsvoort, B., Cook, Elizabeth A.J., Lankester, F., Özkan, Ş., Rosenstein, P.K., Semango, G., Wheelhouse, N., Wilkes, A., Arndt, Claudia

“…In Kenya, enteric methane (CH4) EI related to calf mortality is assessed by estimating lifetime enteric CH4 emissions and total carcass production from dams and their offspring. The EI is compared between the observed scenario (16% calf mortality) and alternative scenarios (8, 4, and 0% calf mortality). …”

Economic evaluation of crossbreeding for dairy production in a pasture based production system in Kenya by Kahi, A.K., Thorpe, W.R., Nitter, G., Arendonk, Johan A.M. van, Gall, C.F.

“…These were used to predict and compare, first, performance of cows under nine crossbreeding strategies and, second, the performance of the production systems when applying the strategies that included maintaining the purebred S dams and bulls required for the production of crossbreds. …”

Do calves in tropical areas behave differently when artificially milk-fed than when nursed restrictively? by Aspegren-Güldorff, Anette

“…The R-calves were sniffed, licked and rubbed by their dams, but also sniffed, licked and rubbed their dams during the restrictively suckling. …”

Development of an IgY-Based treatment to control bovine Coronavirus diarrhea in dairy calves by Bok, Marina, Vega, Celina Guadalupe, Castells, Matias, Colina, Rodney, Wigdorovitz, Andres, Parreño, Gladys Viviana

“…Standard practice dictates that to prevent BCoV diarrhea, dams should be immunized in the last stage of pregnancy to increase BCoV-specific antibody (Ab) titers in serum and colostrum. …”

Genomic data enables genetic evaluation using data recorded on low-middle income country smallholder dairy farms by Powell, O., Mrode, Raphael A., Gaynor, Robert Chris, Johnsson, M., Gorjanc, G., Hickey, J.M.

“…The objective of this study was to use simulation to quantify the power of genomic information to enable genetic evaluation under such conditions.The results from this study show: (i) the genetic evaluation of phenotyped cows using genomic information had higher accuracy compared to pedigree information across all breeding designs; (ii) the genetic evaluation of phenotyped cows with genomic information and modelling herd as a random effect had higher or equal accuracy compared to modelling herd as a fixed effect; (iii) the genetic evaluation of phenotyped cows from breeding designs with strong genetic connectedness had higher accuracy compared to breeding designs with weaker genetic connectedness; (iv) genomic prediction of young bulls was possible using marker estimates from the genetic evaluations of their phenotyped dams. For example, the accuracy of genomic prediction of young bulls from an average herd size of 1 (μ=1.58) was 0.40 under a breeding design with 1,000 sires mated per generation and a training set of 8,000 phenotyped and genotyped cows.This study demonstrates the potential of genomic information to be an enabling technology in LMIC smallholder dairy production systems by facilitating genetic evaluations with in-situ records collected from farms with herd sizes of four cows or less. …”

Molecular and serological diagnosis of multiple bacterial zoonoses in febrile outpatients in Garissa County, north-eastern Kenya by Wainaina, Martin, Lindahl, Johanna F., Mayer-Scholl, A., Ufermann, C.-M., Domelevo Entfellner, Jean-Baka, Roesler, U., Roesel, Kristina, Grace, Delia, Bett, Bernard K., Al Dahouk, S.

“…Additionally, patients who sourced water from dams/springs, and other sources (protected wells, boreholes, bottled water, and water pans) had 2.39 (95% CI 1.22–4.68, p-value = 0.01) and 2.24 (1.15–4.35, p-value = 0.02) times higher odds of exposure to <i>C. burnetii</i> than those who used unprotected wells. …”

Interactions between health and farm-labor productivity by Asenso-Okyere, Kwadwo, Chiang, Catherine, Thangata, Paul, Andam, Kwaw S.

“…Agricultural development may lead to environmental change with adverse health impacts: for example, irrigation dams that create suitable conditions for mosquitoes may lead to increased incidence of malaria locally. …”

Bulldozers against mosquitoes: Environmental management options for malaria control in North-Central Sri Lanka. [Abstract only]. by Boelee, Eline, Weerasinghe, A.K., Amerasinghe, Priyanie H., Piyaratne, M.K., Perera , D., Amerasinghe, Felix P.

“…After intervention, larval abundance of An. varuna, a secondary malaria vector, increased at two of the sampling points, probably as a result of human activities upstream, such as the construction of temporary dams for irrigation. Natural precipitation and supplementary water releases from the upstream reservoirs increased the water level and reduced breeding levels down to a negligible level within two months. …”
