The effect of a feed additive supplemented with porcine plasma protein on growth performance and selected biochemical indices of nursing piglets

Abstract

The aim of this study was to evaluate the health state, performance, and selected serum biochemical indices in nursing piglets after supplementation of a feed additive containing porcine plasma protein in comparison to the control group fed a standard pre-starter feed mixture. The study was carried out in the conditions of industrial farming. Four sows of the Large White swine breed with their litters were included in the study. Piglets were homogenously distributed into control (22) and experimental (24) groups according to weight and sex. Piglets in both groups suckled their mothers' milk. In addition, piglets in the experimental group were also fed a feed supplemented by porcine plasma protein (5%), starting on the third day post partum, whereas piglets in the control group were offered a standard pre-starter feed mixture. We recorded average daily weight gains calculated per the 27-day trial, and body weight at weaning. Clinical findings, mortality, and selected biochemical indices of protein (total immunoglobulins, total protein, albumin, creatinine, urea), and energy (glucose, total cholesterol, total lipids) metabolism were assessed as well. Results of the study showed a significant difference (P < 0.01) in average daily weight gains in the experimental group compared to the control group (0.245 kg and 0.177 kg, respectively). Addition of plasma protein in the experimental group also resulted in a significantly higher serum concentration of total immunoglobulins, total protein and creatinine, and a significantly lower concentration of urea and albumin in this group compared to the control group at weaning.

Spray-Dried Porcine Plasma Promotes the Association Between Metabolic and Immunological Processes at Transcriptional Level in Gilthead Sea Bream (Sparus aurata) Gut

“…In our study, the transcriptomic analysis revealed that DEGs obtained corresponded mainly to biological processes related to "Cellular catabolic process (GO:0044248)", "Energy derivation by oxidation of organic compounds (GO:0015980)", and "Response to organic substance (GO:0010033)". These processes are probably correlated with the previous reported improved growth performance, feed intake, and feed efficiency promoted by dietary inclusion of SDPP in this species (Gisbert et al, 2015;Reyes-López et al, 2021), rainbow trout (Campbell et al, 2003), Nile tilapia (de Araújo et al, 2017), and higher vertebrates including pigs (Angulo and Cubiló, 1998;Van Dijk et al, 2002;Kósa et al, 2019), poultry (Beski et al, 2016;Dabbou et al, 2020), and cats (Rodríguez et al, 2016). In 2001, van Dijk et al (2001 reported that dietary SDPP levels up to 6% increased both average daily gain and feed intake in the first 2 weeks in a dose-dependent fashion and improved feed conversion ratio (FCR) in piglets.…”

The influence of hypothermia prevention by application of skin moisture absorbent on the value of body temperature, body weight and blood parameters in piglets

“…Cabrera et al (2012) note that IgG concentration is associated with a positive correlation with the concentration of total protein in pig blood. According to Kósa et al (2019) recorded concentration of total proteins is 50 ± 3.19g and 51.39 ± 21.29g. The same authors state that higher amounts of total protein occur as a consequence of improved gut function and increased food intake.…”
