Effects of breed exoticness and agroecological zones on selected production and fertility traits in multibreed dairy cattle in Kenya por Oloo, Richard Dooso, Ekine-Dzivenu, Chinyere C., Ojango, Julie M.K., Mrode, Raphael A., Okeyo Mwai, Ally, Chagunda, Mizeck G.G.

“…A multiple linear regression model was fitted for AFC and a mixed-repeatability model for test-day MY and CI to determine the effect of exoticness on these traits and to assess whether this effect changed in the different agroecological zones. Overall, EC2 cows had lower AFC than EC1 cows (32.4, se = 0.2 vs. 34.0, se = 0.2 months). …”

First report of Rice yellow mottle virus on rice in the Democratic Republic of Congo por Hubert, J.G., Pinel Galzi, A., Dibwe, D., Cinyabuguma, E., Kaboré, A., Fargette, D., Silué, D., Hébrard, E., Séré, Y.

“…Recently, efforts have been directed to shift from the traditional upland system to lowland and irrigated systems in which water availability allows sequential planting and maintenance of higher crop intensity. This agricultural change may increase insect vectors and alternate host plant populations which may result in higher RYMV incidence in DRC (3). …”

Linking spatio-temporal variation of crop response with sediment deposition along paddy rice terraces por Schmitter, P., Dercon, G., Hilger, T., Hertel, M., Treffner, J., Lam, N., Duc Vien, T., Cadisch, Georg

“…In general, the spatial variation of rice grain yield was strongly and significantly linked to sediment induced soil fertility and textural changes, such as soil organic carbon (r 0.34/0.77 for Cascades 1 and 2, respectively) and sand fraction (r −0.88/−0.34). …”

Weight gain and enteric methane production of cattle fed on tropical grasses por Korir, Daniel, Marquardt, Svenja, Eckard, Richard, Sánchez, Andrea C., Dickhoefer, Uta, Merbold, Lutz, Butterbach-Bahl, Klaus, Jones, Christopher S., Robertson-Dean, M., Goopy, John P.

“…Conclusion: Even though animal performance and MY among treatments did not differ, the animals had higher MY and Ym than currently estimated by the Intergovernmental Panel on Climate Change. Implication: The three grasses supported similar animal growth rate, implying that growing of higher-yielding grasses such as Napier offers an opportunity to optimise land productivity in the tropics. …”

Efficacy of bentonite and fumonisin esterase in mitigating the effects of aflatoxins and fumonisins in two Kenyan cattle breeds por Kemboi, D., Antonissen, G., Ochieng, P., Croubels, S., Baere, S. de, Scippo, M.-L., Okoth, Sheila A., Kang'ethe, Erastus K., Faas, J., Doupovec, B., Lindahl, Johanna F., Gathumbi, J.

“…The addition of bentonite in a diet contaminated with AFB1 led to a decrease in milk aflatoxin M1 (AFM1) concentration of 30% and 43%, with the carry-over subsequently decreasing from 0.35% to 0.20% and 0.08% to 0.06% for crosses and Borans, respectively. No significant change was observed in the sphinganine/sphingosine (Sa/So) ratio following feeding with FUM alone or in combination with fumonisin esterase; however, the ability of fumonisin esterase to hydrolyze FUM into less toxic fully hydrolyzed FUM and partially hydrolyzed FUM was evident in the rumen fluid and feces. …”

The Legacy of the Soviet Agricultural Research System for the Republics of Central Asia and Caucacus por International Service for National Agricultural Research

“…This was influenced by several factors such as a favorable economic situation before World War I, a rapid increase in agricultural production as a result of the liberal reforms conducted by the government in 1906-1911, and the high priority given by the government to agricultural production. This change was reflected in the increase of the total budget of the Department (Ministry) of Agriculture from 2.4 million rubles in 1895 to 29.4 million rubles in 1913. …”
