background: the immunity and health of newborn calf are related to immunoglobulins uptake from colostrum where treatment of colostrum may improve the uptake. objectives: the purpose of this study was to investigate the effect of controlled heat-treating of colostrum and antibiotic addition on immunoglobulins absorption, performance and health parameters of calf. methods: the colostrum pool was ...

Due to the range of its constituents, colostrum has been considered as a supplement for various diverse purposes. This study was conducted to examine the effect of supplementary bovine colostrum on serum malondialdehyde (MDA), antioxidant activity (AOA) and glucose in a diabetic rodent model. Sixty male Wistar rats were divided into 10 groups of six rats each for 40 days as follows: non-diabeti...

aflatoxin m1 (afm1) is an important mycotoxin frequently found in milk and dairy products. dairy products and colostrum may be contaminated by aflatoxin m1 when dairy cattle have fed with aflatoxin b1-contaminated feeds. this study was undertaken in a dairy farm around tehran province to determine the presence and level of aflatoxin m1 (afm1) in spray dried and lyophilized colostrum samples. in...

Colostrum yield and composition of 40 Landrace×Large White sows were determined from the onset of parturition until 24 h post partum. Colostrum yield was calculated by adding individual piglets' colostrum intakes for each litter. Colostrum was assayed for prolactin, progesterone, oestradiol-17β, immunoglobulin G and its nutritional composition was determined. Piglets' individual colostrum intak...

BACKGROUND Previous studies have shown a high prevalence of failure of passive transfer of immunity (FPT) in Swiss dairy calves. OBJECTIVES To investigate risk factors associated with poor colostrum quality and FPT on Swiss dairy farms. ANIMALS Colostrum and serum samples from 373 dam-calf pairs at 141 farms. METHODS The gamma globulin (Gg) concentrations of the dams' colostrum and the ca...

OBJECTIVE To evaluate alpha-tocopherol concentrations in maternal serum and colostrum under fasting and postprandial conditions. METHODS Thirty healthy childbearing women were recruited in a public maternity hospital, and samples of blood, fasting colostrum, and postprandial colostrum were collected from them up to 12 hours after delivery. RESULTS The serum alpha-tocopherol concentration wa...
