The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

This work was carried out to apply a simulation model for the bioeconomic evaluation of feeding strategies for dairy herds and evaluate the physical productivity and the bioeconomic efficiency of feeding systems for dairy cows using feeding forage based strategies for cows with five levels of milk yield. An computational platform developed with the programs CNCPS v5.0 and electronic spreadsheets of Microsoft Excell® was used, in way to simulate the production and demands of nutrients of a complete lactation for […]

This work was carried out to evaluate the bioeconomic efficiency of cows of different levels of milk yield per lactation, under different feeding strategies. The bioeconomic evaluations was carried out in cows of five milk yield levels and seven feeding strategies The simulation model was developed with the programs CNCPS v5.0 and electronic spreadsheets of Microsoft Excell®, in way to simulate the production and demands of nutrients of a complete lactation for cows of different milk yield levels. The bioeconomic […]

This work was carried out to development a alternative methodology for the bioeconomic evaluation of feeding strategies for dairy herds and evaluate the physical productivity and the bioeconomic efficiency of feeding systems for dairy cows when different feeding strategies forages based are used for cows of five levels of milk yield. The computational platform was developed with the programs CNCPS v5.0 and electronic spreadsheets of Microsoft Excell®, in way to simulate the production and demands of nutrients of a complete […]
