Proposta de um sistema de produção de leite com dietas à base de palma forrageira.

Abstract

Agreste de Pernambuco is home to the state's main dairy basin, accounting for approximately 75% of production. Due to the edaphoclimatic characteristics of the region (Semi-arid), characterized by low rainfall and high temperatures, challenges related to forage production must be faced in order to sustain dairy production systems in the region. Thus, the implementation of high-yielding roughage can be achieved through appropriate agricultural practices, the use of technologies, the selection of varieties adapted to the region's climate and the adoption of good management practices. In this way, fodder palm has been a valuable option for livestock farming in the Agreste region of Pernambuco, contributing to animal food security during periods of drought and offering a sustainable alternative for feeding livestock in the semi-arid region. The aim was to develop a milk production system with palm-based diets, based on the identification in the literature of the main reference indicators to be improved in order to increase the sustainability of dairy farming in Pernambuco. After identifying them and based on zootechnical indices considered achievable, a stabilized herd was idealized and diets based on fodder palm were calculated to meet the needs of this herd. Subsequently, the reference indices were recalculated and showed a significant improvement, indicating that palm can be an extremely important strategy for daisy fanning in the state.
