The study on availability of cow colostrum (C) and cow colostrum protein concentrate (CC) derived from membrane filtration was conducted on Olkuska breed lambs. The lambs were assigned to 4 groups receiving IgG addition in cow colostrum or colostrum concentrate: group I – control, group II – 7.49g IgG in 150 ml C, group III – 7.09 IgG in 125 ml CC, and group IV – 14.18 IgG in 250 ml CC. The lam...

Porcine colostrum and milk were separated into the acid-soluble and casein fractions by acidification followed by centrifuge. The acid-soluble fraction of porcine colostrum was further separated by liquid chromatography and anisotropic membrane filtration. Trypsin and chymotrypsin inhibitory capacity in porcine colostrum, milk and their components was determined by incubating bovine trypsin or ...

Changes in the composition of colostrum and milk fatty acids during the first month of lactation of ten 3-years-old White Shorthaired goats fed a winter diet were investigated. Thirty-eight fatty acids (FAs) were identified in the milk fat. Saturated FAs accounted for 67.0% of the total determined FAs in colostrum and 62% at 30 days post partum. Monounsaturated FAs made up 28.2% of the total FA...

In 2006, a new haemorrhagic syndrome affecting newborn calves, Bovine Neonatal Pancytopenia (BNP), was reported in southern Germany. It is characterized by severe bleeding, destruction of the red bone marrow, and a high case fatality rate. The syndrome is caused by alloreactive, maternal antibodies that are ingested by the calf with colostrum and result from a dam vaccination with one particula...

OBJECTIVE To investigate the effect of vitamin A supplementation on the retinol concentration in colostrum under fasting and postprandial conditions. METHODS This was a quasi-experimental study, with before and after assessments, conducted with 33 patients treated at a public maternity hospital. Blood and colostrum samples were collected under fasting conditions in the immediate postpartum pe...

OBJECTIVE To evaluate and compare the levels of α-tocopherol in colostrum and in the serum of healthy and diabetic mothers. METHODS This cross-sectional study enrolled 51 volunteer mothers, 20 with the diagnosis of gestational diabetes mellitus and 31 without associated diseases. Serum and colostrum samples were collected in fasting in the immediate postpartum period and α-tocopherol was anal...

Mycobacterium avium ssp. paratuberculosis (MAP) infections cause major losses to the dairy industry. Transmission of MAP occurs primarily via feces and in utero, but MAP can also be excreted in colostrum and milk. The objective of this study was to determine whether colostrum and milk fed to calves are important risk factors for infection with MAP. A questionnaire was sent to 1,050 farms partic...

We studied the effects of amounts of colostrum consumed on intestinal morphology and proliferation and digestive enzyme activities in neonatal calves. Group GrCmax calves were fed colostrum from the first milking undiluted on d 1-3 and diluted with 25, 50, 75 and 75 parts of a milk replacer on d 4-7. Group GrC1-3 calves were fed colostrum from milkings 1-6 up to d 3 and then a milk replacer up ...

The purpose of this study was to compare the effects of rat colostrum and mature milk on newborn rat gastrointestinal growth under conditions that controlled the possible confounding effects of energy intake and mode of feeding. Newborn Sprague-Dawley rat pups were tubefed equicaloric amounts of rat colostrum or mature rat milk for 40 h before they were killed. Compared to littermates that were...

Colostrum samples from 49 Jersey cows were analyzed for concentrations of trypsin inhibitor, IgG, IgM, IgA, TS, fat, specific gravity, and N fractions. Colostrum (100 ml) was sampled from each cow as soon as possible after parturition. Mean concentrations of IgG, IgM, and IgA were 84.6, 3.4, and 4.5 g/L, respectively. Mean concentration of trypsin inhibitor was 56 mg of trypsin inhibited/dl of ...
