Colostrum is the first milk produced by mammals within a 24 to 72 hour period after parturition.Colostrum contains various proteins, carbohydrates, fats, vitamins and minerals that are essential for the diet of a developing mammalian neonate. It also includes bioactive constituents such as immunoglobulin, antimicrobial peptides and growth factors. Colostrum and fractions thereof may be useful f...

Older parity cows, cows that smaller quantity of colostrum and cows tha with higher IgG concentration. Reducing colostrum is the most practical means by w  Calves fed 8.5% of birth bodyweight in concentration of IgG in serum in the first 3 Feeding calves transition milk subsequent a...

Bovine colostrum is well known for its beneficial properties on health and development. It contains a wide variety of bioactive ingredients that are known to promote a number of cellular processes. Therefore the use of colostrum whey as a feed additive to promote intestinal health has been proposed, yet little is known about mechanisms implicated in its beneficial properties on intestinal epith...

BACKGROUND Bacterial contamination of colostrum is common and can decrease IgG absorption in neonatal calves. Strategies that mitigate this situation without complicating colostrum management will benefit dairy calf health and survival. OBJECTIVES To evaluate the effects of supplementing colostrum with oligosaccharides (OS) on serum IgG concentration and apparent efficiency of absorption of I...

The provision of quality colostrum with a high concentration of immunoglobulins is critical for newborn calf health. Because first colostrum may be low in overall concentration to effectively reduce the risk of newborn infections, we tested equivalent milking fractions of colostrum for possible IgG differences. The objective of this study was to determine if the fractional composition of colost...

Colostrum corpuscles are not always found in so-called colostrum milk; when they are present, the percentage of proteids is higher; as they disappear, the proteid percentage drops. The color of colostrum milk is yellow; this color is especially marked in negroes' milk (observed in four cases not included in this report). The reaction of colostrum milk is alkaline. The specific gravity varies fr...

An investigation was made into the protein profile of colostrum/milk of ten Murrah buffaloes and of their ten buffalo calves during their first week of neonatal life to study the materno-neonatal transfer of immunoglobulins (Ig). Calves were pail fed 3.5 liter of colostrum and/or milk per calf/day exclusively from their dam. First blood sample from newborn calves was collected before colostrum ...

This study aimed to develop Greek style yoghurts with the addition of bovine colostrum. Four yoghurt formulations were produced different colostrum content (0%, 10%, 20% and 30%). The fat, protein, total solids, ash, retinol levels quantified as well colour was measured. A sensory analysis conducted 103 untrained panelists, evaluating attributes appearance, aroma, consistency, flavour, overall ...

Newborn calves are characterised by marked cardio-respiratory, metabolic and endocrine changes which continue during ensuing weeks and months. Thus, although the somatotrophic axis is basically functioning in neonatal calves, it is not yet mature. The speed of the adaptations of the various traits differs widely. The ability to digest colostrum and milk requires specific structures and function...

OBJECTIVE To investigate the association between type of delivery and immunoglobulin concentration in maternal colostrum. METHODS We studied 82 women who were giving birth. Age was between 21 and 41 years, gestational age was 37 or more weeks and parity up to IV pregnancies. The women were in good nutritional condition and did not have any pregnancy or puerperium- associated diseases. The fol...
