Optimized feed planning for a grazing horse production systems

The objective of this study was to develop an economically optimal plan for pasture production and supplementary feeding of horses. The plan was based on the optimization of a multiperiodic linear programming model with the objective of minimizing overall feeding costs, subject to the nutritional co...

The plan was based on the optimization of a multiperiodic linear programming model with the objective of minimizing overall feeding costs, subject to the nutritional constraints of each horse category. The model encompasses a period of one year, from January to December, divided in bimonthly periods.

Literature data on feed nutritional value (crude protein and digestible energy), dry matter intake and nutritional requirements of the horses were also used as technical coefficients.

Objetivou-se planejar e otimizar economicamente a produção de forragem e a alimentação de equinos, visando reduzir os custos de um sistema de produção de equinos em pastejo. O planejamento foi desenvolvido a partir da otimização de um modelo de programação linear multiperiódico com o objetivo de reduzir as despesas com alimentação, sujeita às restrições de exigência nutricional de cada categoria. O modelo contemplou o período de um ano, de janeiro a dezembro, dividido em bimestres. Os coeficientes técnicos variaram entre períodos com base em informações locais sobre a produtividade dos cultivos forrageiros e valores nutricionais dos alimentos (proteína bruta e energia digestível) sugeridos na literatura, considerando as condições climáticas e a sazonalidade de produção, observados na Coudelaria. De acordo com os resultados, é possível reduzir os custos no sistema de produção de forragem e na alimentação de equinos, bem como substituir o uso de concentrado comercial por aveia produzida no local. 2017-12-07T04:54:35Z 2017-12-07T04:54:35Z 2010 Artigo R.
