Suplemento mineral aniônico para vacas no periparto: parâmetros sanguíneos, urinários e incidência de patologias de importância na bovinocultura leiteira

Abstract: A fim de avaliar o efeito do suplemento mineral aniônico sobre parâmetros sanguíneos, urinários e incidência de hipocalcemia e retenção de placenta, dezoito vacas de aptidão leiteira com grau de sangue 7/8 Holandesa preta e branca, com 440-620 kg e 5-10 anos, foram divididas com delineamento em blocos em função da ordem de parto em dois grupos: controle (BCAD=46,38mEq/kg de MS) e tratamento (com adição de suplemento mineral aniônico e BCAD = -249,28mEq/kg de MS). Foram monitorados níveis de cálcio total e pH n… Show more

“…In many of these studies, the frequency of subclinical hypocalcemia was above 60% and the lowest prevalence was of 33% (Paula et al, 2011;Souza Júnior et al, 2011;Greghi et al, 2014;Moreira et al, 2015;Silva Filho et al, 2015). There is a remarkable difference when we compare these results with a Chilean study with grazing cattle conducted from 2003 to 2011, using a cut point of 8.0mg/dL for hypocalcemia, that find a much lower frequency of only 3.4% of animals below the cut point (Wagemann et al, 2014).…”

“…An anionic diet with selenium helps reduce the occurrence of retained placenta (GREGHI et al, 2014). Sufficient quantities of pre-partum mineral (5 mg/day selenium), preferably associated with vitamin E, help improve the immune response mediated by lymphocytes B and T and mainly neutrophils, responsible for phagocytosis and for degrading the placentomes in order to promote the placenta release (NOBRE, 2010).…”

“…Isso nos mostra que a idade ao abate dos animais pode ser diminuida resultando em maior produção e qualidade da carne, além de tornar a atividade mais eficiente do ponto de vista econômico (Montemór & Marçal, 2009). Greghi et al (2014) identificaram diferença significativa da ação do selênio, administrado para vacas no periparto, como redutor dos casos de retenção de placenta.…”
