On-farm instruments for assessing colostrum quality are needed in order to ensure that the calf is supplied with enough IgG to avoid failure of passive transfer. The aim of this study was to evaluate methods for estimating the IgG concentration in cows' colostrum. This research included 126 colostrum samples from 21 Danish farms with different breeds, ensuring a broad variation pattern in IgG, ...

Filed Under: Bovine Colostrum Colostrum Colostrum Health Antioxidants are a type of molecule that can neutralize harmful substances, called “free radicals”, which can damage living cells. Free radicals are also responsible for food spoilage and the degradation of other materials such as gasoline, rubber and lubricating oils. Antioxidants that are useful in protecting cells from free radical dam...

The COVID-19 pandemic continues to be a global issue that draws worldwide attention. Countries are racing develop vaccines and drugs combat the virus. Immunomodulators used in some of prevention efforts. Any drug or substance affects immune system is classified as an immunomodulator. Bovine colostrum example Colostrum mammary gland’s first secretion after birth, it differs from mature milk cont...

Immaturity of the neonatal immune system is causative for high morbidity in calves and colostrum intake is crucial for acquiring passive immunity. Pathogenesis is promoted by reactive oxygen species accumulating at birth if counter-regulation is inadequate. The flavonol quercetin exerts antioxidative and anti-inflammatory effects that may enhance neonatal health. The aim of this work was to stu...

Colostrum intake from birth to 24 h after the onset of parturition (T24) was estimated for 526 piglets from 40 litters. Plasma concentrations of immunoglobulin G (IgG), lactate, glucose and cortisol were determined at T24 for six piglets per litter. Plasma IgG concentration was also assayed at weaning (28 days) on the same piglets. Rectal temperature was measured at T24 on all piglets. Mortalit...

The aim of this study was to investigate histology characteristics in the small intestine of Santa Ines lambs fed bovine or ovine colostrum. At 0 and 6 h of life, 12 newborn lambs received 250 ml of first milking bovine colostrum (BC) and another 12 animals received 250 ml of first milking ovine colostrum (OC). Samples of duodenum, jejunum and ileum were collected at 24 and 72 h of life. Six an...

This article is a review of the factors that influence the sow’s colostrums and milk yield. Colostrum is secreted from the udder immediately after farrowing and is a rich source of highly digestible nutrients, which are critical to the survival of the newly born piglet. Colostrum contains natural growth factors for the normal development of vital life-sustaining organs. The litter performance b...

This paper reviews the composition of colostrum and the potential preventive and therapeutic use of this "first milk" for treating various gastrointestinal disorders in humans. Colostrum is a complex biological liquid that is richer in antimicrobial peptides, immune-regulating compounds and growth factors than the subsequent mature milk. The main functions of colostrum are to provide essential ...

OBJECTIVE To determine and to compare the levels of secretory immunoglobulin A in samples of colostrum and milk of mothers of term and preterm neonates. MATERIAL AND METHODS The levels of secretory immunoglobulin A of 10 mothers of term neonates and 10 mothers of preterm neonates were determined from 5 mL of colostrum or milk collected on the 1st, 4th, 10th and 15th days of the puerperal peri...

IN an earlier paper [Dann, 1932, 2] an account was given of experimental work devised to ascertain the channels through which young mammals receive supplies of vitamin A up to the time of weaning. The placenta, the colostrum and the milk are the three available channels; but of their relative importance and the factors controlling the efficiency of each we know almost nothing. The experiments p...
