Colostrum is a breast milk produced after the birth of the newborn and lasts for 2-4 days. Colostrum is very important part of breast milk and lays down the immune system and confers growth factors and other protective factors for the young ones in mammals. This is the source of passive immunity achieved by the mother and is transferred to the baby. This is the major source of secretory IgA and...

This qualitative study explored the experiences and breastfeeding outcomes of a group of mothers who expressed colostrum in the antenatal period. In-depth interviews were conducted over the telephone with 12 women who had attended a unique antenatal lactation clinic appointment at 37 weeks' gestation. Seven main response themes were identified. Most women reflected positively upon their attenda...

Several factors can affect lamb body weight (BW) and immune status during the first days of life, including colostrum source and timing of the first colostrum feeding. The aim of this study was to evaluate the effects of colostrum source (goat or sheep) and timing of the first colostrum feeding (2 or 14h after birth) on lamb BW and immune status. In this study, 40 lambs were removed from their ...

PURPOSE To assess the alpha-tocopherol concentration in the serum and colostrum of adolescent and adult mothers and to determine the nutritional adequacy of vitamin E in the colostrum offered to infants. METHODS In total, 72 pregnant women participated in the study, 25 adolescents and 47 adults. An amount of 5 mL of blood and 2 mL of colostrum were collected under fasting conditions for the a...

The effects of the addition of nonimmunoglobulin protein on absorption of immunoglobulin G (IgG) from colostrum or colostrum supplement products were determined in two experiments. In experiment 1, 48 Holstein calves were fed 4 L of pooled maternal colostrum or 4 L of reconstituted colostrum supplement with 0, 200, or 400 g of added whey protein concentrate or casein. In experiment 2, 38 Jersey...

Blood, colostrum and saliva samples were serially taken from 6 multiparous sows from day 109 of gestation until day 3 postpartum. Plasma was assayed for oestradiol-17beta (E2), progesterone (P4), prolactin (PRL), cortisol, immunoglobulin G (IgG) and lactose. Colostrum was assayed for E2, P4, IgG and lactose. Lactoserum, obtained after ultra centrifugation of colostrum, was assayed for PRL. Sali...

the main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum igg1 and igg2 concentrations, serum igg1 and igg2 concentrations of calves and efficiency of igg1, igg2 and total ig absorption. for this purpose, thirty primiparous and twenty multiparous holstein cows were used in...

A randomized controlled clinical trial was conducted using 1,071 newborn calves from 6 commercial dairy farms in Minnesota and Wisconsin, with the primary objective being to describe the effects of feeding heat-treated colostrum on serum immunoglobulin G concentration and health in the preweaning period. A secondary objective was to complete a path analysis to identify intermediate factors that...

Heavy exercise causes gut symptoms and, in extreme cases, "heat stroke" partially due to increased intestinal permeability of luminal toxins. We examined bovine colostrum, a natural source of growth factors, as a potential moderator of such effects. Twelve volunteers completed a double-blind, placebo-controlled, crossover protocol (14 days colostrum/placebo) prior to standardized exercise. Gut ...

BACKGROUND Colostrum is the first liquid that is produced in the first few days after delivery. It is the perfect first food for newborns which is considered as an infant's first immunization. Despite of this fact colostrum is discarded as unclean and bad for the infant's health. This study aimed to investigate the prevalence and the factors associated with colostrum avoidance in Woldia, Kobo a...
