TL;DR: The composition of human milk is the biological norm for infant nutrition and contains many hundreds to thousands of distinct bioactive molecules that protect against infection and inflammation and contribute to immune maturation, organ development, and healthy microbial colonization.
TL;DR: Three basic physiological functions must be maintained during the periparturient period if disease is to be avoided: adaptation of the rumen to lactation diets that are high in energy density, maintenance of normocalcemia, and maintenance of a strong immune system.
TL;DR: In this article, the general shape of the curve, defined by the locus of weekly yield of a single lactation, remains substantially unchanged, and it is shown that the animal which produces milk at a moderate level steadily throughout her lactation is preferred to one which produces a great deal of milk at her peak but little thereafter.
Abstract: MANY factors may influence the total milk yield of a single lactation, but the general shape of the curve, defined by the locus of weekly yield, remains substantially unchanged. Economically, the configuration of the curve is important, for the animal which produces milk at a moderate level steadily throughout her lactation is to be preferred to one which produces a great deal of milk at her peak but little thereafter (see Cersovsky1 for a review of the literature).
TL;DR: Current research and practice demonstrate that 3 to 5% fat may be added to diets for lactation to increase energy intake of high-producing cows and/or to reduce starch feeding, thereby increasing the ratio of forage to concentrate to prevent depression of milk fat.
TL;DR: The composition of breast milk and the factors that affect it during the course of breast feeding are discussed, allowing for the improvement of clinical practices, infant feeding and the understanding of immune responses to infection and vaccination in infants.
