Effect of intercropping with herbaceous legumes on the yield and quality of Napier grass in the central highlands of Kenya por Mwangi, David Miano, Giller, Kenneth E., Thorpe, W.R., Thomas, D.

“…The limited supply of fodder, when combined with the same quantities of purchased concentrates, results in average daily milk yields of 6-8 litres from high grade dairy cows (Omore et al., 1996; Staal et al., 1997). As a step towards developing higher yielding forage systems to support increased milk production, Napier grass was intercropped with three herbaceous legumes and harvested at different heights and frequencies to study the effects on forage yield and quality.…”

Co-expression of bovine leukemia virus and bovine foamy virus-derived miRNAs in naturally infected cattle por Petersen, Marcos Iván, Suarez Archilla, Guillermo, Perez, C.V., Gonzalez, Diego D., Trono, Karina Gabriela, Mongini, Claudia, Jaworski, Juan Pablo, Carignano, Hugo Adrian

“…We identified the co-expression of seven BLV-derived miRNAs (blv-miR-B1-3p, blv-miR-B2-5p, blv-miR-B2-3p, blv-miR-B3-5p, blv-miR-B3-3p, blv-miR-B4-3p, and blv-miR-B5-5p) and three BFV-derived miRNAs (bfv-miR-BF1-5p, bfv-miR-BF1-3p, and bfv-miR-BF2-5p) in naturally BLV-infected cows. Besides, seven differentially expressed bovine miRNAs (bta-miR-375, bta-miR-133a, bta-miR-677, bta-miR-1, bta-miR-3613a, bta-miR-9-5p, and bta-miR-95) were identified between cows with high BLV proviral load and uninfected counterparts (|fold change| > 1.5 and q-value < 0.05). …”
