γ-Aminobutyric acid (GABA) is a ubiquitous nonprotein amino that has multiple physiological functions and received significant attention in the pharmaceutical food industries. Although there are many GABA-producing bacteria, high cost of strain cultivation limits its additive raw material application. In our study, Lactobacillus hilgardii GZ2, novel strain, was investigated. We attempted to rep...

Since Cuthbertson first published his important investigations, the metabolic response to trauma has been the subject of continuous study in many disciplines of medicine (1-8). An impressive body of knowledge has been accumulated with respect to changes in plasma electrolyte concentrations, urinary electrolyte excretion, body composition, and adrenocortical activity. There is general agreement ...

The composition of human milk provides the model for estimated total protein and essential amino acid requirements during infancy. However, both the total protein content and the concentrations of individual proteins in human milk change throughout the first year of lactation. Recent reassessments of estimated requirements have resulted in lower total protein recommendations and have emphasized...

Skeletal abnormalities consisting of shortened long bones, enlarged joints and splayed front feet in newborn calves were associated with cows fed apple pomace supplemented with nonprotein nitrogen (NPN) during late gestation. Measurements of x-ray films of the metacarpus and lumber vertebrae from 86 calves in three trials showed that calves from dams fed apple pomace and NPN had longer, thicker...

Attempt was made to study the factors that affect maximum yield of nonprotein nitrogen from various skeletal muscles. The results showed that sonification was the most, effective method out of the various extraction procedures used for the extraction of NPN, while the use of tungstic acid as protein precipitant was most suitable. The pH studies showed that pH 2 gave the optimal yield of NPN. Re...
