The American Academy of Pediatrics Committee on Nutrition presents an updated review of lactose intolerance in infants, children, and adolescents. Differences between primary, secondary, congenital, and developmental lactase deficiency that may result in lactose intolerance are discussed. Children with suspected lactose intolerance can be assessed clinically by dietary lactose elimination or by...

Patients with chemotherapy-induced gastrointestinal mucositis suffer from anorexia, diarrhea, and stomach pain, often causing weight loss and malnutrition. When the intestinal function during mucositis would be known, a rational feeding strategy might improve the nutritional state, accelerate recuperation, and increase survival of mucositis patients. We developed a methotrexate (MTX)-induced mu...

This study was designed to determine the effect of some environmental factors on milk yield and composition in Saanen goats CSN3 AGPAT6 gene polymorphisms production traits. were genotyped for traits, samples collected during lactation, yield/compositions each goat specified. In terms genes, genotypes defined by PCR-RFLP. The (MY), lactation length (LL), protein, fat, total solid (TS), not fat ...

Grain legumes are feedstuffs with high nutritional value that could replace soybean in dairy sheep nutrition. This be beneficial terms of economic efficiency and environmental sustainability. However, research regarding their potential effects on animal performance is scarce. The objective was to assess milk production body condition score (BCS) intensively reared ewes after replacing meal a mi...

This study describes milk production and milk composition of Iberian red deer (Cervus elaphus hispanicus) females (hinds) and the effect of calving date and BW change of hinds by milking over 34 wk. All hinds produced milk throughout the 34-wk study period, well over the standard lactation period. Total milk yield was 224.1 +/- 21.1 L, and daily production was 0.91 +/- 0.06 L. Milk yield decrea...

Changes in protein absorption through the intestinal mucosa occur with aging and might reflect modifications in enterocyte membrane characteristics. We have observed that bovine beta-lactoglobulin (beta-LG) was efficiently transported across the small intestine of adult rats in vitro and that 12-16% of the absorbed protein was recovered intact or as large hydrophobic peptides. Ten percent lacto...

metabolizable protein (mp) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (rup) sources. effects on production efficiency and n utilization of early post-partum dairy cows were determined. forty-two multiparous and 16 primiparous holstein cows were assigned to the diets in a randomized complete block design immediately after part...

Epithelial cells from freshly isolated mammary glands of mature virgin mice make minute amounts of casein and exhibit low levels of lactose synthetase A-protein (a UDPgalactosyltransferase) activity. They have barely detectable lactose synthetase B-protein (oc-lactalbumin) activity. When cultured in the presence of insulin, hydrocortisone, and prolactin, mammary explants from mature virgin mice...

A number of specific duplex DNA sequences which correspond to varying lengths of the lactose operator region have been synthesized by a combination of chemical and enzymatic methods. Repressor binding studies on these synthetic duplex operator molecules show that all the nucleotides essential for full lactose operator-repressor interactions are included in a 17-nucleotide-long duplex DNA that c...
