A FARINHA DE OVO EM PÓ PODE SUBSTITUIR PARCIAL DO PLASMA SANGUÍNEO PARA LEITÕES NAS FASES PRÉ INICIAIS DE CRECHE?

Abstract

Due to the high cost of feeding in pig farming, the demand for using products with lower production costs increases every day. Blood plasma in swine nutrition is widely used in feed production, but its cost is high. In view of the above. The objective of this study was to use the partial replacement of blood plasma by powdered egg flour for piglets in the nursery phase: pre-initial I and pre-initial II, using four treatments in different proportions, 0%, 20%, 40% and 60%, respectively. The experimental design employed was in randomized blocks repeated twice in time, the experiment consisted of four treatments, with four replications in each time, with three piglets per pen representing the experimental unit. The zootechnical performance parameters were evaluated: daily feed intake (CRD), daily weight gain (GPD), feed conversion rate (TCA). Statistical analysis was performed using the Statistical Analysis System statistical software, ANOVA was used to compare the variables. No significant differences were obtained at the 5% probability level in the Dunnet test in this experiment, therefore, the replacement of powdered egg flour by blood plasma did not affect the zootechnical performance indices, being a good option for using egg flour. egg powder to reduce production costs. Keywords: Animal nutrition, zootechnical performance, animal welfare, powdered egg meal and blood plasma.
