Gastroduodenal Motility

It is known that breast milk empties more quickly from the stomach than does infant formula. We studied the difference in gastroduodenal motility between neonates fed with human milk and those fed with infant formula. Twenty-four five-to 36-day-old neonates were fed with mother's breast milk or with a cow's milk-based formula. Postprandlial gastroduodenal contractions were recorded manometrically for three hours. Repetitive, high-amplitude nonmigrating contractions were the dominant wave form during the postprandial period. The number of episodes, duration, amplitude, and frequency of nonmigrating contractions were not different following the different feedings. The migrating myoelectric complex, which signals a return to the interdigestive (fasting) state, appeared in 75% of breast milk-fed infants but only 17% of formula-fed infants (P < .05) within the three-hour recording period. Because contractions were similar following the two meals, but a fasting state recurred more rapidly in breast-fed infants, we conclude that factors other than phasic, nonpropagated antroduodenal contractions were responsible for the differences in gastric emptying between breast milk and formula.

Β Lactoglobulin

Previous studies have suggested that an unidentified cow's milk protein, other than β-lactoglobulin and casein, might play a pathogenetic role in infant colic. Therefore, a radioimmunoassay was used to analyze human breast milk and infant formula samples for the presence of bovine IgG. Milk samples from 88 of the 97 mothers tested contained greater than 0.1 µg/mL of bovine IgG. In a study group of 59 mothers with infants in the colic-prone 2- to 17-week age group, the 29 mothers of colicky infants had higher levels of bovine IgG in their breast milk (median 0.42 µg/mL) than the 30 mothers of noncolicky infants (median 0.32 µg/mL) (P < .02). The highest concentrations of bovine IgG observed in human milk were 8.5 and 8.2 µg/mL. Most cow's milk-based infant formulas contained 0.6 to 6.4 µg/mL of bovine IgG, a concentration comparable with levels found in many human milk samples. The results suggest that appreciable quantities of bovine IgG are commonly present in human milk, that significantly higher levels are present in milk from mothers of colicky infants, and that bovine IgG may possibly be involved in the pathogenesis of infant colic.

Cow's Milk

The objective of this paper was to study the amino acid composition of donkey milk inhabiting the Kegety gorge of the Chui region. As well as human milk, donkey and mare’s milk is albumin; the amount of casein is 35-45%, while cow’s milk is casein milk with casein content over 75%. The peculiarity of albumin milk is a higher biological and nutritional value, due to better amino acid balance, high sugar content and the ability to form small, delicate flakes when souring. In terms of its properties, albumin milk is closest to human milk and is the best substitute for it. The obtained results showed that the quantitative content of 7 essential amino acids out of 8, such as lysine, phenylalanine, leucine, isoleucine, methionine, valine, threonine is relatively high compared to other amino acids. Despite the absence of tryptophan in donkey milk, the percentage of 8 essential amino acids in donkey milk protein exceeds that in mare and cow’s milk.

Serum Immunoglobulins

Serum concentrations of immunoglobulins (IgA, IgG, and IgM) were studied in 64 preterm infants with gestational age of 31 to 36 weeks (mean 33.2 weeks), between 1 week and 4 months after birth. Infants were fed solely human milk or formula based on cow's milk. Infants fed formula exhibited significantly higher IgA levels at the age of 9 to 13 weeks than infants fed human milk. Infants given human milk who received more than 60% of their feeding in the hospital from their own mother had significantly higher IgA levels at the age of 3 weeks than did those receiving less than 30% of their feeding from their own mother. At 1 week of age, formula-fed infants with gestational age of 31 to 33 weeks had a significantly lower mean IgG concentration than those with gestational age of 34 to 36 weeks. However, the two term subgroups of infants receiving human milk, had similar mean concentrations of IgG and the value for infants of 31 to 33 weeks of gestation was significantly higher than that for formula-fed infants at the same gestational age. Serum IgM concentrations were similar whether infants were receiving human milk or formula. The formula feeding caused a more rapid maturation of IgA than did human milk. Results suggest that preterm infants may absorb IgA from the milk of their own mothers and that preterm infants with gestational age of 31 to 33 weeks may absorb IgG from human milk.
