Extract

The profitability, competitiveness and sustainability of dairy industry depend on minimizing feed costs while reducing nutrient excretion to minimize environmental impacts. A variety of software programs are available that designed to evaluate and formulate rations for dairy cattle. These programs differ greatly in their components and the types of objective functions available for ration formulation and completeness and versatility of report writing (Eastridge et al., 1998; Fox et al., 2003). The purpose of this study was to compare the performance of lactating dairy cows fed rations formulated with Spartan dairy ration balancer (Spartan) and Cornell Net Carbohydrate and Protein System (CNCPS) software.
