Calcium Requirements of Growing Pigs »

The role of calcium and phosphorus in animal nutrition has received much attention in recent years, and many studies have been made to determine the need of these minerals in the nutrition of the pig. Much of the work has dealt with deficient rations and means of correcting the deficiencies. Recently the individual minimum requirements of these minerals have received the attention of investigat...

Grass silage in diets for organic growing-finishing pigs

In this study, organically raised pigs received an increasing proportion of grass silage up to 10 and 20% dry matter in the daily ration in the grower and finisher period, respectively, to determine the effects of grass silage on feed intake and growth performance. The pigs receiving a mixture of grass silage and compound feed ingested 0.3 kg DM/d (13% of their daily ration) as grass silage and...

A dynamic growth model for prediction of nutrient partitioning and manure production in growing-finishing pigs: Model development and evaluation.

Nutrient loading and air emissions from swine operations raise environmental concerns. The objective of the study was to describe and evaluate a mathematical model (Davis Swine Model) of nutrient partitioning and predict manure excretion and composition on a daily basis. State variables of the model were AA, fatty acids, and a central pool of metabolites that supplied substrate for lipid synthe...
