1. Three equations are proposed to describe the postnatal growth of animals. The first equation is the "law of diminishing return" relating the body mass of the animal to cumulative feed intake. The second equation relates cumulative feed intake to age. Substitution of the second into the ...
作者: A Kertz 摘要: The classic review on growth and body composition of cattle was published in 1955 (Reid et al.) and established some key elements:There is an inverse relationship between body water and fat. Thus, fattening is largely a replacement of water by fat. 年份: 2022 收藏...
This presentation aims to describe how the basic events in prenatal muscle development and postnatal muscle growth are controlled by the insulin-like growth factor system (IGF). The prenatal events (myogenesis) cover the rate of proliferation, the rate and extent of fusion, and the differentiation...
The process of biological development is an amazing feat of tightly regulated cellular behaviours - differentiation, movement, and growth - powerful enough to result in the emergence of a highly complex living organism from a single cell, the fertilized egg. Principles of Development clearly illustrate...
The mechanisms underlying kidney development in mice and humans is an area of intense study. Insights into kidney organogenesis have the potential to guide our understanding of the origin of congenital anomalies and enable the assembly of genetic diagnostic tools. A number of studies have delineated ...
His research includes work on price adjustment, consumer behavior, financial markets, monetary and fiscal policy, and economic growth. His published articles have appeared in academic journals, such as the American Economic Review, Journal of Political Economy, and Quarterly Journal of Economics, and ...
the medical service system has been improved; equal access to basic public health services has been enhanced; and our capacity to control disease has been greatly strengthened. After many years of efforts, we have improved people’s conditions and blazed a development path suited to China's reali...
