EFEITOS DA SUBSTITUIÇÃO PARCIAL DO PLASMA SANGUÍNEO POR FARINHA DE OVO EM PÓ SOBRE O DESEMPENHO ZOOTÉCNICO DOS LEITÕES

Abstract

A study was conducted to evaluate different levels of blood plasma substitution by egg powder flour in the diet of weaned piglets on zootechnical performance. The work was developed in the swine farm Experimental of Unioeste. The piglets were distributed in an experimental design in complete randomized blocks, with four treatments, repeated twice in time, totaling eight replicates, with three piglets per experimental unit. The initial weight was used as a criterion for the constitution of the blocks and the treatments consisted of four levels of plasma substitution by egg powder flour (FO), FO 0%, FO 20%, FO 40%, and FO 60%. The results were evaluated by means of the mean initial weight, final weight, daily feed intake, daily weight gain and feed conversion rate. The substitution of blood plasma by egg powder flour did not affect the performance of the animals in the initial phases and the total period. All statistical analyses were performed using the statistical software Statistical Analysis System (SAS Inst. Inc., Cary, NC, USA). The substitution of blood plasma by egg powder flour did not affect the performance of the animals in the initial phases and the total period.
