Animals are biological transformers of dietary matter and energy to produce high-quality
foods and wools for human consumption and use. Mammals, birds, fish, and shrimp require …

The Cornell Net Carbohydrate and Protein System (CNCPS) is a mathematical model that
estimates cattle requirements and nutrient supply based on animal, environmental, and feed …

A deterministic and mechanistic growth model was developed to dynamically predict growth
rate, accumulated weight, days required to reach target body composition, carcass weight …

The release of methane from ruminant livestock is a problem not only because it contributes
to greenhouse gas emissions but also because it affects feed energy utilization and animal …

A meta-analysis was conducted to determine NE and net protein requirements of growing
bulls, steers, and heifers of Nellore purebred and Nellore× Bos taurus crossbreds. A …

Abstract The National Animal Nutrition Program “National Research Support Project 9”
supports efforts in livestock nutrition, including the National Research Council's committees …

Protein supply and requirements by ruminants have been studied for more than a century.
These studies led to the accumulation of lots of scientific information about digestion and …

Mathematical models can be used to improve performance, reduce cost of production, and
reduce nutrient excretion by accounting for more of the variation in predicting requirements …

Demand for animal products is growing faster than for any other agricultural product. As a
result, pressure for greater output from cultivated pastures is expected to increase. Assuming …

An experiment was conducted to evaluate whether a reduction in dietary crude protein (CP)
content affects animal performance, energy and protein requirements, N losses, and enteric …
