Colostrum (or first milk) is the food produced by all mothers in specific mammalian species, ruminants, monogastric and marine mammalians for their newborns during 24–48 h post-partum. provides to neonate essential nutrients necessary week of life, but effect colostrum shows a long-term not limited these days. considered be safe human consumption. Some young children can show at beginning colos...

OBJECTIVE Enterotoxigenic Escherichia coli (ETEC) is the leading cause of travelers' diarrhea. The aim of this study was to investigate the ability of a powdered extract of hyperimmune bovine colostrum to protect against diarrhea in volunteers challenged with ETEC. MATERIALS AND METHODS Tablets were manufactured from a colostrum extract from cattle immunized with 14 ETEC strains, including se...

The effects of colostral fat level on voluntary colostrum and ME intake were determined in 25 newborn pigs during the first postnatal day. Within a litter, five pigs were obtained before nursing and allotted on the basis of initial body weight (BW) at 2 h of age to one of the five treatments: killed or ad libitum bottle-fed sow colostrum containing 2.5, 5.0, 7.5, or 10.0% of total fat. A total ...

Shotgun proteomics, using amine-reactive isobaric tags (iTRAQ), was used to quantify protein changes in milk fat globule membranes (MFGM) that were isolated from d 1 colostrum and compared with MFGM from d 7 milk. Eight Holstein cows were randomly assigned to 2 groups of 4 cow sample pools for a simple replication of this proteomic analysis using iTRAQ. The iTRAQ labeled peptides from the exper...

Medium lacking serum but supplemented with milk will support the growth of sparse cells in culture. Milk obtained within 8 h after the birth of a calf (day 1 colostrum) is the most effective in supporting proliferation. In mixed cultures of early-passage bovine embryonic kidney (BEK) or early-passage calf kidney (CK) cells, both epithelial cells and fibroblasts grow in Dulbecco's modified eagle...

Bovine colostrum, the first milk that cows produce after parturition, contains high levels of growth factors and immunomodulatory components. Some healthy and diseased individuals may gain health benefits by consuming bovine colostrum as a food supplement. This review provides a systematic, critical evaluation of the current state of knowledge in this area. Fifty-one eligible studies were ident...

Dietary fiber given during pregnancy may influence sow endocrinology and increase piglet BW gain during early lactation. The aim of the current study was to determine whether dietary fiber given to sows during late pregnancy induces endocrine changes that could modulate sow colostrum production and, thus, piglet performance. From d 106 of pregnancy until parturition, 29 Landrace×Large White nul...

Transfer of sufficient immunoglobulin G (IgG) to the neonatal calf via colostrum is vital to provide the calf with immunological protection and resistance against disease. The objective of the present study was to determine the factors associated with both colostral IgG concentration and colostral weight in Irish dairy cows. Fresh colostrum samples were collected from 704 dairy cows of varying ...

BACKGROUND Inadequate colostrum supply results in insufficient intake of macronutrients and bioactive factors, thereby impairing gastrointestinal development and the maturation of glucose metabolism in neonatal calves. The flavonoid quercetin has been shown to have health-promoting properties, including effects in diabetic animals. However, quercetin interacts with intestinal glucose absorption...

Hormonal changes involved in the farrowing process partly control the initiation of lactation. Inducing farrowing by injection of PG may alter the normal prepartum hormonal cascade. The aim of the study was to investigate the consequences of farrowing induction on colostrum yield and composition, as well as newborn piglet growth. Gilts were treated with 2 mg of alfaprostol on d 113 of gestation...
