“…This results in negative effects on the puerperium, the milk yield and the liver metabolism (Herdt, 1988;Chapinal et al, 2011 and2012). A BHBA level between 1.2 and 1.4 mmol/l is associated with an increased occurrence in metritis, clinical ketosis, lack of oestrus postpartum and severe mastitis (LeBlanc, 2010;Seifi et al, 2011). In our study, 10 cows of group D and only 1 cow of group CM exceeded a level of 1.4 mmol/l.…”

The objective of this field study with an automatic milking system was to evaluate the effects of omitting the dry period on health and productivity during the subsequent lactation in dairy cows. A total of 98 German Simmental cows of six Southern German farms were assigned randomly to two experimental groups: The first group was dried-off 56 days before calving (D for dried-off, n = 49), and the second group was milked continuously during this period until calving (CM for continuous milking, n = 49). From the latter a third group emerged, including cows that dried-off themselves spontaneously (DS for dried-off spontaneously, n = 14). Blood serum values of glucose, β-hydroxybutyrate (BHBA), non-esterified fatty acids (NEFA) and IGF-1 showed most pronounced fluctuations in D cows. Over the entire study period, the concentrations of BHBA and NEFA were markedly lower in the CM and DS groups. Furthermore, IGF-1 concentration was lowest for D cows and also decrease in back fat thickness was more pronounced. Mean concentration of milk protein was markedly higher in CM and DS cows (3.70% and 3.71%) compared with D cows (3.38%). Owing to the lower 305-day milk yield (−15.6%) and the lower total milk yield (−3.1%), the total amount of produced protein in the subsequent lactation was 2.5% (6.8 kg) lower, although the additional protein amount in CM cows from week −8 to calving was 35.7 kg. The greatest benefit resulted from positive effects on fertility and the lower incidence of diseases: CM cows had their first oestrus 1 week earlier compared with D cows, they also conceived earlier and showed a significantly lower risk of developing hypocalcaemia, ketosis and puerperal disorders. The present study showed that the costs of medical treatment and milk losses were twice as high in D cows, compared with CM and DS cows, and thus the reduced costs because of the more stable health outweighed the financial losses of milk yield by + 18.49 € per cow and lactation.

“…Early blood profiles included packed cell volume and hemoglobin along with glucose, proteins, and minerals. More recently, metabolites such as nonesterified fatty acids (NEFA) and BHB have been added to the profiles to monitor energy balance (6). There are acutephase responses, oxidative stress, and abomasal tissue damage in DA cases (7)(8)(9).…”

“…Alguns trabalhos relacionaram a hipocalcemia subclínica ao aumento dos riscos de deslocamento de abomaso (Massey et al 1993, Risco & Melendez 2011, Chapinal et al 2011. Vacas com níveis de cálcio abaixo de 8,8mg/dL nas primeiras duas semanas pós-parto, além de apresentarem elevado risco de desenvolverem DA, também apresentaram maior probabilidade de serem descartadas da produção nos primeiros 60 dias de lactação (Seifi et al 2011). Durante o período de transição, 51% das vacas apresentaram hipocalcemia subclínica no momento do parto, porém, não houve diferença entre vacas hipocalcêmicas e normocalcêmicas quanto a ocorrência de DA e outras doenças (Chamberlin et al 2013).…”

Hipocalcemia no deslocamento de abomaso de bovinos: estudo de 39 casos

RESUMO: Este estudo avaliou o status do cálcio sérico em 39 vacas com deslocamento de abomaso (DA), provenientes de 30 propriedades leiteiras selecionadas, na região de Campos Gerais no Paraná. O diagnóstico do deslocamento de abomaso foi realizado por percussão auscultatória, além dos sinais clínicos e informações da anamnese. Previamente ao procedimento cirúrgico, amostras de sangue foram coletadas para a mensuração dos níveis sanguíneos de cálcio, albumina, proteína e glicose. Como grupo controle, amostras de sangue foram coletadas de vacas hígidas que se encontravam em semelhante período de lactação. Das 39 vacas com deslocamento de abomaso, 35 apresentaram hipocalcemia e no grupo controle, apenas um animal. Concentrações sanguíneas de glicose e proteína foram inferiores nos animais com DA, quando comparados com animais do grupo controle.
