Analysis of two alternative management systems for the production of fall born beef calves in western Oregon

Creator:

Rosecrans, John Gerald

Abstract:

Two management systems were evaluated in terms of the effects on calf growth, on calf weight produced per cow per year, and on reproductive performance of fall calving cows. The alternative management systems tested were twin foster calf production and, delayed weaning, production of single suckled calves weaned at the...

Computer simulation of beef cattle production systems in the Llanos of Columbia

Creator:

Levine, Joel Martin

Abstract:

A simulation model capable of execution on a programmable calculator was developed to study voluntary intake, liveweight change, and fertility of grade Zebu cows in the Llanos of Colombia. Organic nitrogen in the diet and meta bolic weight were used to predict intake; age, liveweight, and energy concentration were the...
