Oxidative and biochemical profile of Gyr dairy heifers during the peripartum period

چکیده
ABSTRACT O período de transição em vacas leiteiras aumenta o suprimento oxigênio aos tecidos e a produção espécies reativas oxigênio. Junto com comprometimento do sistema antioxidante, gera estresse oxidativo, que pode estar ligado ao desenvolvimento diversas doenças. Este estudo teve como objetivo avaliar oxidativo 35 novilhas Gir, durante periparto. Foram analisados ácido úrico, cobre, ferro, zinco, albumina, bilirrubina total, superóxido dismutase (SOD) glutationa peroxidase (GSH-Px). Um modelo linear distribuição Poisson foi aplicado usando procedimento GENMOD. A primeira medida (30d antes parto) considerada referência (T0), as amostras foram coletadas 16 dias parto (T1) sete (T2), 14 (T3), 28 (T4) 42 pós-parto (T5). Cobre, zinco albumina variaram dentro da faixa referência, apesar ter havido aumento no cobre 45,92% T3. Os níveis úrico aumentaram transição, sem diferença significativa até pré-parto, quando observado 67,57%, sendo sua maior concentração observada T4. SOD um (300%) GSH-Px (36%) final experimental, acompanhada por adaptações bioquímicas para garantir uma resposta antioxidante eficaz. Dessa forma, pode-se concluir periparto causa Gir.

Prevalence of intramammary infections at prepartum and postpartum in primigravid heifers from five dairy herds located in the central dairy area of Argentina was determined. Mammary secretion samples from 140 heifers (560 mammary quarters) were obtained 14 days prior to the expected calving day and within 7 days after parturition and subjected to bacteriological analysis. No clinical mastitis c...

Milk samples were collected from 180 heifers from 20 herds around parturition to study the prevalence and persistence of intramammary infection (IMI). A total of 3382 quarter milk samples was collected each week from 4 wk before parturition to 4 wk after parturition. Staphylococcus chromogenes, the most commonly found bacterial species before parturition, was isolated from 15% of all quarters. ...

Hematological and biochemical profile during gestation period in Sahiwal cows
It was demonstrated in this study that the mean values of the different red blood cell count and white blood cell parameters showed significant changes during gestation. RBC, PCV and Hb increased while total WBC and segmented neutrophils increased after the second gestation period in the second period. The numbers of total leucocytes and segmented neutrophils increased after the second period.
