Effect of Tithonia diversifolia (Hemsl.) A. Gray intake on in vivo methane (CH4) emission and milk production in dual-purpose cows in the Colombian Amazonian piedmont por Rivera, Julián Esteban, Villegas, Gonzalo, Chará, Julian, Durango, Sandra G., Romero Sánchez, Miguel Antonio, Verchot, Louis V.

“…The objective of this study was to determine the effects of the T. diversifolia inclusion in a basal diet of Brachiaria humidicola on methane (CH4) emissions by enteric fermentation, and on milk yield and quality in dual-purpose cows. The polytunnel technique was used for the determination of methane yield and two diets were evaluated (Diet 1: Brachiaria humidicola 100%; Diet 2: T. diversifolia 15% + B. humidicola 85% dry matter basis) in the moderate rainy and rainy seasons using a cross-over experimental design; milk production was measured by daily milk weighing, and milk quality was determined using a LACTOSCAN analyzer. …”

Evaluation of GnRH- versus estradiol-based protocols for ovulation synchronization in postpartum Bos taurus grazing beef cows submitted to fixed-time artificial insemination por Ferre, Luis Bernardo, Cerviño, Maria Natalia, Jaeschke, Julian, Itterman, Maximiliano, McLean, Jaime, Aragon, Agustin, Fernández, Manuel, Villa, Matías, Formia, Néstor, Jaureguiberry, Maria, Rearte, Ramiro, Kjelland, Michael E., Colazo, Marcos G., Thomas, Jordan M., De la Sota, Rodolfo Luzbel

“…Plasma P4 concentrations at IVPD removal were greater (P < 0.05) in cows subjected to the 7-day GnRH or 7 & 7 GnRH protocols and a greater number of cows (P < 0.05) had at least one CL at IVPD removal compared to cows subjected to the 7-day EB protocol. …”

The digesta passage rate among dairy cows with different abilities to consume large quantities of roughage : its impact on the milk production, and the reliability of the chemical fibre marker por Eklund, Maria Elisabeth

“…The objectives of the present master thesis were to investigate the passage rate among lactating Holstein and Swedish red dairy cows to investigate the hypotheses of: 1) The cows’ individual total mean retention time (TMRT) has a negative relationship to the cows’ individual forage intake capacity. 2) A reduced TMRT contributes to a reduced feed efficiency, but a higher milk yield. 3) The chromium (Cr) mordanted fibre marker used in the present study is a reliable substitute for rumen evacuations when measuring TMRT for the solid digesta fraction. …”
