Aiming to evaluate spray-dried animal plasma (PSP) by piglets weaning at 28 days of age was made a experiment with 128 piglets of a 7.635 ± 0.103 kg initial body weight allocated in a experimental block design, composed by four treatments, eight replicates and four animals a replicate. The treatments used were: 1) Diets without spray-dried plasma (PSP) and with dried milk (LDP), from 29 to 42 days of age; 2) Diets with LDP and 2.8% of PSP from 29 to 35 days of age in the phase one and 2.0% of PSP from 36 to 42 days of age in the phase two; 3) Diets with LDP and 4.2% of PSP from 29 to 35 days of age in the phase one and 3.0% of SPP from 36 to 42 days of age and 4) Diets without LDP and 5.6% of PSP from 29 to 35 days of age and 4.0% of PSP from 36 to 42 days of age in the phase two. From 42 to 56 days of age (phase three) all treatments animals received initial diets without PSP. It was not verified effect (P≥0.10) of SPP inclusion on the average daily feed intake (ADFI), in the period one. On the period one it was verified linear effect (P≤0.10, IBN = 6.8371GPMD 3.5732CRMD) of the treatments over the bio-nutritional index and over the inclusion of PSP (P≤0.10; Ŷ = 0.1364 + 0.0100X) over the daily weight gain and that the feed conversion ratio got better as the level of PSP in the diets was raised. There was no effect of treatments over the diarrhea index. It concluded that the inclusion level of PSP in the first week post-weaning diets for 28 days of age weaning piglets is 5.6%.
