Effect of colostrum supplementation on baby pig performance
Two experiments evaluated the effect of colostrum and energy supplementation on the performance and immune response of baby piglets. In Exp. 1, 301 newborn pigs (Line 600 × 241; DNA, 1.48 kg) were used in a 21-d study. Pigs were weighed and allotted to one of three treatments at 6-h of age in a …

Influence of Feeding Pooled Colostrum or Colostrum Replacement on IgG Levels and Evaluation of Animal Plasma as a Milk Replacer Protein Source
… of immunoglobulin G (IgG) from maternal colostrum (n = 39) or a colostrum replacement product derived from bovine serum (n = 39). Calves were also fed milk replacer with (n = 38) or without (n = 40) animal plasma to 29 d of age to determine the effect of plasma protein on IgG status, …

Effects of gestation length and supplemental dietary fat on colostrum and milk composition in swine
… farrowing and supplemental dietary fat on colostrum and milk composition in the sow. The induction of premature farrowing (d 112 of gestation) was shown to affect the composition of colostrum and milk, particularly by altering the fat content. The average fat content of mammary secretions …

The effects of supplementation of β-carotene during the close-up period on cows, colostrum, and calves
… of β-carotene supplementation on the cow, her colostrum, and her calf. The trial was conducted on a large, commercial dairy farm in northern Indiana. Ninety-four multiparous Holstein cows were assigned to either a treatment or control group. Each cow individually received a concentrate mix …

Photoperiod and Temperature-Humidity Index during the Dry-Period Impact Colostrum and Milk Production in Dairy Cattle
Colostrum quality is critical to calf health as colostrum provides immunoglobulins (Ig) that are critical for a calf's immune system. Despite close management of factors known to affect colostrum production, 23% of dairy cows are still producing inadequate volume or quality of colostrum, which …

Genetic and Maternal Factors Underlying Early Milk Production and Their Influence on Calf Health
… 1) establish phenotypic relationships between colostrum composition traits, milk production traits, and calf health, 2) determine impact of breed and season on colostrum production and 3) ) elucidate the genetic parameters (i.e. heritability, genotypic, and phenotypic correlations) among …

Use of the Relative Dose Response Assay to Determine the Vitamin A Status of Neonatal Calves: Effects of Season on Colostrum Quality and Immunological Parameters
… of calves was examined. In addition, effects of colostrum quality and season on vitamin A status and health of calves were determined. Blood was sampled from the jugular vein of 16 newborn calves to establish values over a 24 h period for immunoglobulin M (IgM) concentration, hematocrit, serum …

Impact of cross-fostering on the intestinal microbiome and mucosal immune gene expression in neonatal pigs
Colostrum is vital to the newborn pig. Hence, cross-fostering is employed to equalize the number of piglet between litters ensuring colostrum intake for their survival and growth. However, little is known about the impact of cross-fostering on the intestinal microbiome and mucosal immune gene …

Colostrum feeding and its effects on serum cortisol, thyroxine, immunoglobulin G and cytosolic glucocorticoid receptors in skeletal muscle in the bovine neonate
The effect of feeding colostrum or milk to newborn calves on serum cortisol, thyroxine and immunoglobulin G was investigated. Twenty-four calves (12 males and 12 females) were obtained immediately postpartum and randomly assigned to one of two rations after being blocked by breed and sex. Both …

Adoptively transferred maternal colostral cells impact immune status and development in dairy calves
… calves is a problem within the dairy industry. Colostrum is the sole source of maternal immunity for the calf, having a substantial impact on health and survival. To date, colostrum quality is determined by concentration of antibodies. Colostrum also contains proteins and cells, which may …

Avaliação da suplementação de vitamina E sobre a concentração de alfa-tocoferol no leite materno em mulheres com partos prematuros
… milk undergoes variations during lactation, colostrum and milk richer in this micronutrient compared to transitional and mature milk. Newborns, especially premature infants are more susceptible to vitamin E deficiency and to prevent the damage caused by this deficiency has been proposed …

Exploring milk management strategies for improved food safety and health outcomes in the neonate
… in the first 24 hours post-partum is known as colostrum. In bovines, colostrum consumption in calves is associated with improved health and reduced mortality. In humans, fresh mothers’ own milk is regarded as the optimum nutrition for the newborn infant. When mother’s own milk is unavailable …

Serologische Untersuchungen von Sauenmilch und Ferkelblut als mögliche Alternative zur Blutuntersuchung von Muttersauen im Rahmen der Bestandsdiagnostik
… served as the basis for the evaluation of the colostrum, milk and piglets' blood samples. Sensitivity, specifity, positive and negative predictive factor were determined. Further more the development of the milk antibody concentration p.p. and a comparison of sows' and piglets' antibody titers …

Maternal rumen-protected methionine supplementation alters dairy calf development, postnatal growth, plasma biomarkers, and liver one-carbon metabolism
… randomly allocated considering dam treatment and colostrum as follows: 1) calves from CON cows and colostrum from CON cows (n = 21); 2) calves from CON cows and colostrum from MET cows (n = 18); 3) calves from MET cows and colostrum from MET cows (n = 22); and 4) calves from MET cows and colostrum …

Generation and characterisation of biologically active milk-derived protein and peptide fractions
… in the production of such peptides. In addition, colostrum was characterised as a source of bioactive proteins and peptides. Firstly, a comprehensive study was carried out on the composition and physical properties of colostrum throughout the early-lactation period. Marked differences in the …

The Production and Ingestion of Antibodies in Milk
… immunity. The newborn calf is dependent upon colostrum which is the maternal source of passive immunity and only under special circumstances can calves be reared without colostrum. Ehrlich (13) postulated that colostrum had specific antibodies which were absorbed by the young, and that this …
