Viabilidade econômica do uso de fontes lipídicas na dieta de vacas em lactação

Abstract:  RESUMOObjetivou-se, com este estudo, avaliar a viabilidade econômica do uso de diferentes fontes lipídicas na dieta. O trabalho foi implantado em uma área de 42ha, dividida em oito piquetes, formada de Brachiaria brizantha. Utilizaram-se 12 vacas mestiças Holandês x Zebu, distribuídas em três quadrados latinos 4 x 4. Os quatro tratamentos foram constituídos de diferentes fontes lipídicas, como se segue: dieta sem fonte extra de lipídeos; dieta com caroço de algodão; dieta com óleo de soja; e dieta com óleo d… Show more

“…The positive effect resulted from the lack of roughage in the diet without, which provides an improvement in the digestibility of these nutrients, due to the increase in EE and TDN intakes caused by the increased amount of total digestible carbohydrates from the diet, thereby increasing the availability of EE and TDN. According to Murta et al (2013), an increase in EE digestibility can be explained by the reduction of the contribution of endogenous losses when a higher intake of this nutrient occurs. However, working with steers, Ítavo et al (2002) did not observe any influence of the concentrate level on TDN intake.…”

“…O fluxo de caixa compreendeu um período de 7 anos, sendo esse determinado em função da vida útil dos tanques-rede ser 16 ciclos de cultivo. Os indicadores de viabilidade econômica, considerados como variáveis de saída (outputs) foram: valor presente líquido (VPL) e taxa interna de retorno (TIR), ambos conforme o proposto por Murta et al (2013); Payback descontado de acordo com Siqueira et al (2011); e a relação benefício/custo (R B/C), consoante Maneschy (2009), os quais são comumente utilizados para análises de investimentos financeiros.…”

“…The economic viability indicators, considered as the simulation model output variables were: Net Present Value (NPV) and Internal Rate of Return (IRR), both as proposed by Murta et al (2013); Discounted Payback according to Smith et al (2011); Equivalent Uniform Annual Value (EUAV), which determines the equivalent uniform series of all costs and revenues, using a minimum rate of attractiveness and; Cost-benefit analysis (CBA), according to Maneschy, Santana and Veiga (2009), which are commonly used for financial investments analysis.…”
