The aim of the present study was to determine changes in oxidative status plasma sows during periparturient period using markers lipid and protein peroxidation intensity. Plasma from 12 pregnant gilts collected on days 14 1 before parturition 1, 7 postpartum used study. As indicators alterations status, concentrations thiobarbituric acid reactive substances (TBARS) sulphydryl groups (SH groups)...

abstract the effect of different levels of potassium permangenate (kmno4) on quality of mango fruits were studied over a period of 21 days. a factorial trial in the form of complete randomized design as three levels of kmno4 (0, 5 or 10 g. kg-1 fruit) and three time period (7, 14 or 21 days) was used. means were compared using duncan’s test (p< 0.05). compositional parameters (ph, acidity, tota...

1. Rat dams given a diet containing 100 g maize oil/kg for approximately two weeks before mating and during the first 14 d of gestation, were given the same diet or one containing 100 g hydrogenated coconut oil/kg (essential fatty acid (EFA)-deficient) in place of maize oil until parturition. After parturition the dams were given the same diets and all progeny were weaned to the maize oil diet ...

BACKGROUND Suckling can be a peaceful or vulnerable event for goats and kids, whereas, separation is suggested as stressful. The aim of this study was to investigate physiology and behaviour in these two different situations in dairy goats. METHODS Four studies were performed with seven goats kept with their first-born kid in individual boxes. The goats were videotaped and heart rate and arte...

Pasteurella pneumotropica was isolated in essentially pure cultures from the bowels of hamsters with enteritis 7 days after parturition. Newly received hamsters showed presence of P. pneumotropica in their nasal cavities but not in their uteri, lungs, spleens, or bowels.

BACKGROUND Eating and rumination variables were recorded in ten healthy cows over 5 days (group A) to generate reference intervals for comparison with the same variables recorded in ten cows in advanced pregnancy from ten days prepartum to ten days postpartum (group B). A pressure sensor integrated into the noseband of a halter recorded individual chewing movements. The endpoints calculated on ...

Dairy cows suffer from an intense energy deficit at parturition due to the onset of copious milk synthesis and depressed appetite. Despite this deficit, maternal metabolism is almost completely devoted to the support of mammary metabolism. Evidence from rodents suggests that, during periods of nutritional insufficiency, a reduction in plasma leptin serves to co-ordinate energy metabolism. As an...

The process of parturition involves the complex interplay of factors that change the excitability and contractile activity of the uterus. We have compared the relative gene expression profile of myometrium from rats before parturition (21 days pregnant) and during delivery, using high-density DNA microarray. Of 8,740 sequences available in the array, a total of 3,782 were detected as present. F...
