Comparison of methods to measure enteric methane emissions from ruminants: an i...
Ribeiro, Angelita Alecchandra; Pinedo, Lerner Arévalo; Codognoto, Luciane da Cunha; Cavali, Jucilene; Porto, Marlos OliveiraThe agricultural industry is the main emitter of methane (CH4) and nitrous oxide (N2O), gases that each have a global warming potential that is greater than that of CO2 by 23 and 298 times, respectively. On a global scale, enteric fermentation from ruminant animal production (especially of cattle and sheep) is responsible for between 21% and 25% of total anthropogenic CH4 emissions. The search for effective, si...

Oliveira, Palloma Vitória Carlos de; Batista , Nayane Valente; Silva , Nícolas Lima; Melo , Vitor Lucas de Lima; Firmino, Salenilda SoaresThe objective was to carry out lamb carcass evaluation in a confinement system fed with 100% concentrated diet and diet with the inclusion of residual oil, in order to identify which diet provides the best performance. Fifteen male sheep, not castrated, crossbred from Dorper × Santa Inês, aged six months, confined in collective pens for 50 days were used. The treatments were as follows: Control Diet (TC) - Tift...
SILAGENS DE CAPIM-ELEFANTE E EMBAÚBA ADITIVADA COM PRODUTOS ALTERNATIVOS NA AMA...
Santos, Betina Raquel Cunha dos; Gomes, Fábio Augusto; Pinedo, Lerner Arévalo; Maia, Gerbson Francisco NogueiraObjetivou-se avaliar o padrão fermentativo e a bromatologia da silagem de capim- elefante cultivar Napier com as folhas de Embaúba na proporção de 50:50 aditivada com torta de semente de cupuaçu, cana-de-açúcar e fubá de milho em diferentes níveis. O experimento foi realizado em delineamento inteiramente casualizado, com quatro repetições por tratamento. Foram testados os tratamentos (0%), (5%), (10%) e (15%) d...

Braga, Gustavo José; Pinedo, Lerner Arévalo; Herling, Valdo Rodrigues; Luz, Pedro Henrique de Cerqueira; Lima, César Gonçalves deThe objective of this study was to determine dry matter production (DMP) and tissue flow of Tifton 85 bermudagrass (Cynodon spp.) under the effect of four doses of nitrogen (NO-O, N1-45, N2-90, N3-135 mg/kg soil) in the form of nitrate of ammonium in a randomized design, with five replications. Nitrogen increased DMP of leaves and stems (p < 0.05), but it did not influence the DMP of roots, stem/leaves ratio an...
