Mammalians undergo dramatic organ-specific as well as metabolic and endocrine changes after birth. Nutrient intake shifts from continuous glucose supply via the placenta to discontinuous colostrum and milk intake with lactose and fat as main energy sources. The development of the neonatal calf is influenced by colostrum intake when compared with colostrum replacement diets. Besides establishing...

The efficacy of a 2-month treatment with oral colostrum in the prevention of flu episodes compared with antiinfluenza vaccination was evaluated. Groups included healthy subjects without prophylaxis and those receiving both vaccination and colostrum. After 3 months of follow-up, the number of days with flu was 3 times higher in the non-colostrum subjects. The colostrum group had 13 episodes vers...

BACKGROUND Changes in colostrum composition of Egyptian buffaloes and Holstein cows collected at calving, 6, 12, 24, 48, 72, 96, 120 h and after 14 days of parturition were studied. Total solids, total protein, whey proteins, fat, lactose and ash contents were determined. Macro- and micro-elements, IgG, IgM, IGF-1, lactoferrin and vitamins (A and E) were also estimated. RESULTS At calving, th...

It is widely recognized that an early and high intake of colostrum is a major determinant of piglet survival during the early suckling period. The production of colostrum, however, is very variable among sows and the factors affecting this variability are not well known. Factors such as number of parity and genotype do seem to influence colostrum yield and composition. The endocrine status of t...

Neonatal dairy animals are born agammaglobulinemic and must obtain immunoglobulins (Ig) during the period of macromolecular transport within the first 24 h of life. Maternal colostrum has been the traditional source of Ig and recommendations for provision of 2 L of colostrum in two separate feedings within the first 24 h are widespread. However, stubbornly high levels of neonatal mortality and ...

BACKGROUND UNICEF and WHO recommend colostrum as newborns' perfect food that should be initiated within the first hour after birth. OBJECTIVE To assess colostrum avoidance practices and associated factors among mothers of children aged <24 months in Raya Kobo district, North-eastern Ethiopia. METHODS A quantitative community-based cross-sectional study supplemented by qualitative method was...

Feeding newborn calves high-quality colostrum is of well-recognised importance as calves that do not receive an adequate concentration of immunoglobulin-G (IgG) have an increased risk of morbidity and mortality. This experiment aimed to characterise IgG concentrations in colostrum from the first milking in New Zealand dairy cows, examine IgG status of calves, and to evaluate the use of a refrac...

This study was designed to compare the absorptive efficiency of IgG from a commercial bovine serum product (bovine serum), cow colostrum (positive control), and two commercial milk-derived IgG supplements (supplement 1 and supplement 2). Newborn Holstein calves, collected at birth and prior to the consumption of colostrum, were allotted to treatment by alternating birth order. Colostrum supplem...

PURPOSE To describe the fatty acid composition of human colostrum in three different regions of China. METHODS Women were recruited from river/lake, coastal and inland regions of China during late pregnancy. Their diet frequency was assessed during the 34th week of pregnancy. Colostrum samples were collected between postpartum days 3 and 5. Thirty-one different fatty acids were separated and ...

BACKGROUND: BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is the main causative agents of neonatal calf diarrhea. Passive transfer of antibodies that is derived from the dams of the calves through their colostrum plays an important role in disease prevention. OBJECTIVES: To determine the presence of natural specific antibodies against K99 antigen in dam’s serum and colostrum as well as in...
