The main aim of this article is to generalize the results of biochemical and molecular research of developing opaque-2 maize seeds (high-lysine mutant of maize) metabolism peculiarities
This review covers the advances of the molecular biology in the study of gene expression characteristics of animals in the amino acid imbalance
Application of a factorial method for determining the needs in metabolic protein and essential amino acids, helps to deepen knowledge on physiology of protein and amino acid supply and allow to improve the standards for dairy cows during the transition period; in insufficient of metabolic protein and essential amino acids increased coefficients of their transformation into net protein and absorptive amino acids as a result of mobilization of body of cows; with an optimal protein nutrition their transformation in net milk protein, lysine and methionine accordingly amounted to 0.67, 0,83 and 0,82. The most significant changes in the concentration of methionine, proline, glutamate, glutamine, glycine were observed in cows before calving and immediately after birth, stabilization of their level starts with a 24 lactation day, that is connected with the peculiarities of the feeding behavior of the cows and the gradual intensification of the processes of metabolism and milk production. To control the status of protein metabolism we have offered benchmarks compositions of free amino acids in cows’ blood plasma phases: 21-0 days before calving, 0-21 and 22-120 days after calving
