Resumo: | Crossbreed F1 Holstein x Gyr cows are proving to be a good alternative for milk production under tropical conditions. In order to contribute to that affirmative, our work focused on clarifying the metabolic patter of F1 Holstein x Gyr dairy cows during the most critical time in the lactation cycle, the transition period, and to compare their performance in two seasons. Blood sampling was performed on 15 cows during summer (January to April) and on 13 cows during winter (May to August), beginning three weeks before the estimated calving date, until 30 days relative to calving. The season had a great influence on the metabolic status. Almost all evaluated metabolites, with exception for aminotransferase (AST), non-esterified fatty acids (NEFA) and beta-hydroxybutyrate (BHBA), that have shown no variation among seasons, demonstrated a different patter between summer and winter. Liver functions were enhanced during the postpartum, with increased liver enzymes activity and increased concentration of cholesterol and BHB. Animals went through negative energy balance (NEB) and an alarming number of animals had experienced subclinical ketosis and high NEFA concentrations. |

A fim de contribuir para essa afirmativa, o nosso trabalho se concentrou em esclarecer e avaliar o perfil metabólico de vacas F1 Holandês x Gir durante o período mais crítico do ciclo de lactação, o período de transição, e comparar seu desempenho em duas épocas do ano. Foram realizadas coletas de sangue em 15 vacas durante o verão (janeiro a abril) e em 13 vacas durante o inverno (maio a agosto), começando três semanas antes da data prevista para o parto até 30 dias depois do parto. A estação teve uma grande influência sobre o perfil metabólico. Quase todos os metabólitos avaliados, com exceção para aspartato aminotransferase (AST), ácidos graxos não esterificados (NEFA) e beta-hidroxibutirato (BHBA), mostraram variação entre estações, demonstrando um comportamento diferentes entre verão e inverno. A atividade hepática aumentou durante o pós-parto, com o aumento da atividade de enzimas do fígado e aumento da concentração de colesterol e BHB. Animais passaram por um balanço energético negativo (NEB) e um número alarmante de animais experimentaram cetose subclínica e altas concentrações de NEFA. De forma geral, o perfil metabólicos dos animais variou consideravelmente entre o verão e o inverno. Apesar disso, a produção leiteira foi similar nas duas estações, o que indica que o cruzamento Holandês x Gir é uma boa opção para a produção de leite em regiões tropicais.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2737910.5433/1679-0359.2018v39n6p2487Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2487-2500Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2487-25001679-03591676-546Xreponame:Semina.
