Abstract

ABSTRACT In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters. Fifty-four castrated male piglets, weaned at an average age of 21 days and an initial average weight of 7.01±0.294 kg, were distributed in a completely randomized block design, with three diets (0%SPC-5%BP, 2.5%SPC-2.5%BP, and 5%SPC-0%BP), six replicates, and three piglets per experimental unit. [...]

Highlights

Weaning is a critical period in piglets because of the stress associated with the change in diet and environment and the immaturity of the digestive and immune systems
In this study, we evaluated the effects of substitution of partial and total spray-dried blood plasma (BP) with soy protein concentrate (SPC) in the diet of post-weaning piglets on their performance, intestinal histomorphometry, and blood parameters
From 21 to 32 and 21 to 42 days of age, daily feed intake, daily weight gain, and final weight of the animals were higher in the group fed 2.5%SPC-2.5%BP and 0%SPC-5%BP

Summary

Introduction

Weaning is a critical period in piglets because of the stress associated with the change in diet and environment and the immaturity of the digestive and immune systems. According to Torrallardona, (2010), its use improves the feed intake and weight gain in piglets compared with other protein sources, whether of animal or vegetable origin. The palatability of blood plasma is responsible for the initial increase in feed intake and, an improvement in post-weaning weight gain (Ermer et al, 1994). The use of spray-dried plasma in feeds is beneficial, mainly in terms of the performance of post-weaning piglets; its price is high (Pettigrew, 2006). The present study sought to assess the effects of substitution of spray-dried plasma with soy protein concentrate in the diet of weaned piglets at 21 days of age on performance, intestinal histomorphometry, and some blood parameters
