This study examined the association between hemoglobin (Hb) concentrations in sows and number of stillborn pigs. Based on late gestation Hb concentrations, prepartum intrapartum pigs was greater (P < .001) anemic than nonanemic sows.

Increasing dietary energy density by feeding supplemented fat may enhance lactation performance as well as metabolic efficiency of lactating cows (Kronfeld 1980). Inadequate energy intake prepartum and during early lactation has been associated with increased incidences of metabolic disorders (Curtis et al. 1985) and poor reproductive performance. The aim of this study was to determine the effe...

Overfeeding during the dry period may predispose cows to increased insulin resistance (IR) with enhanced postpartum lipolysis. We studied gene expression in the liver and subcutaneous adipose tissue (SAT) of 16 Finnish Ayrshire dairy cows fed either a controlled energy diet [Con, 99 MJ/day metabolizable energy (ME)] during the last 6 wk of the dry period or high-energy diet (High, 141 MJ/day ME...

The objective of this study was to determine lactation performance and metabolism of primiparous and multiparous dairy cows fed different levels and sources (inorganic and organic) of Co or given weekly vitamin B(12) injections. Forty-five primi- and multiparous cows at 60 d prepartum were blocked by expected calving date, and randomly assigned to 1 of 5 treatments in a randomized complete bloc...

BACKGROUND Neonatal anxiety and depression and breastfeeding cessation are significant public health problems. There is an association between maternal symptoms of anxiety and depression and early breastfeeding cessation. In earlier studies, the causality of this association was interpreted both ways; symptoms of anxiety and depression prepartum significantly impacts breastfeeding, and breastfe...

The present study aimed to alleviate the negative effects of peripartum and postpartum periods on timing ovarian follicle development, milk composition, as well blood metabolic profiles due Nigella sativa (N. sativa) supplementation. Twenty-seven pregnant Ardi goats were classified using a randomized complete design into three groups: control group two N. groups (10.0 20.0 g seeds per kg diet)....

Two experiments were conducted in consecutive years to determine the effects of prepartum nutrient level and postpartum ruminally undegraded protein intake on nutrient status, milk production, subsequent calf production, and reproductive performance of 126 crossbred, primiparous beef heifers. Prepartum treatments were low nutrient intake (LN) (approximately 2.5 kg of TDN, .5 kg of CP animal-1.d...

The object of this study was to determine the effect of prepartum supplementation of vitamin E with or without injective vitamin E and selenium (Se) on productive and reproductive performances and immune function in dairy cows. Sixty multiparous Holstein dairy cows were divided randomly into three groups at the end of gestation. Cows in each group received one of three treatments: (1) a single ...

The present on-farm research evaluated the occurrence of fatty liver syndrome and its predisposing risk factors for multiparous dairy cows from a commercial herd in Venezuela. Liver biopsy samples were collected at 35 days (d) prepartum (Holstein, n = 14; Holstein × Carora crossbred, n = 17) as well as 1 to 7 d (Holstein, n = 8; Holstein × Carora crossbred, n = 11) and 28 to 35 d (Holstein, n =...
