Use of spray‐dried porcine blood by‐products in diets for young chickens

Abstract

Spray-dried porcine blood plasma (SDBP) or blood cells (SDBC) at amounts of 20 or 40 g/kg were included to the feed mixtures that were given to young chickens within 1-28 (Exp. 1) or 1-30 (Exp. 2) days post-hatch. In comparison with the group fed mixtures containing plant components, chickens fed mixtures supplemented with 40 g/kg of SDBP significantly (p < 0.01) increased the body weight estimated on 14 day of life (Exp. 1). At the age of 28 or 30 days post-hatch, the body weight was improved significantly (p < 0.01 or 0.05) in both experiments. Significant differences (one-factorial anova) in feed conversion among particular feeding groups were stated in Exp. 1 only; however, calculations using two-factorial anova show insignificant differences depending on the used animal meal. In selected blood parameters (IgG, Ht, Hb), insignificant differences between feeding groups were stated. The use of SDBP in feed mixture significantly increased the Na retention in both experiments, and K accretion in Exp. 1 only. Application of SDBC and 40 g/kg of SDBP significantly or insignificantly improved Fe retention. Insignificant diversification of apparent ileal digestibility of nutrients was stated; the crude fat was significantly better digested in treatments fed mixtures with animal meals but kind of animal meal was without any significant effect. Significant differences in digestibility of amino acids were recorded for Pro, Cys, Val, His, Lys and Arg. In chickens fed mixture with SDBC, higher coefficients of apparent digestibility of Cys, Val and His (Exp. 1) and Cys and His (Exp. 2) than in other feeding groups were obtained. The kind of used blood by-products has not affected the histological structure of intestine wall.

Tissue Pathomorphology and Immunohistochemistry in Mink (Neovison Vison) Fed Blood Plasma Supplemented Diet in the Period of Preparation for Breeding

“…The plasma products incorporated into pig diet was found to improve animal performance. In some cases in poultry, however, the preparations decreased bird body weight (7,8,11,14). A histological analysis of the jejunal wall structure in poultry fed a diet supplemented with blood plasma, performed by Jamroz (7), demonstrated that all groups of birds had a normally functioning intestinal wall, which is contrary to the results obtained in the present study.…”

“…These problems have been widely addressed but they still lack good solutions. Recently, blood plasma has been frequently incorporated into diet of many animal species, and its high nutritional value as a feed supplement was confirmed (7,8,9,11,14,17). So far, blood plasma has not been used in carnivorous fur animal feeding, therefore, the present study was conducted to determine the effect of supplemental dietary plasma on mink organism during the preparatory period for the breeding.…”

Natural Pig Plasma Immunoglobulins Have Anti-Bacterial Effects: Potential for Use as Feed Supplement for Treatment of Intestinal Infections in Pigs

“…The present study establishes the potential of ppIgG purified directly from slaughterhouse blood waste as an antibiotics alternative when used as a feed additive. This supplements earlier studies on the effects of orally provided spray-dried plasma on growth and intestinal infections in both swine and chicken and further underlines the importance of immunoglobulins for the effect of SDPP [15,[29][30][31][32]. Furthermore the usage of isolated immunoglobulins from plasma in preventing/treating enteric infections is supported by Pierce et al who found that the plasma proteins with high molecular weight (primarily IgG) reduced ETEC infections in weaner piglets [16].…”

Effect of dietary inclusion of spray‐dried porcine plasma on performance, some physiological and immunological response of broiler chickens challenged with Salmonella sofia

“…Jamroz et al. () also reported a minor reduction in the concentration of IgG as a result of SDPP inclusion in the starter diets of broiler chickens.…”

“…The results of the current study are in line with the findings of Jamroz et al (2011) who observed no significant effect of SDPP incorporation in broiler diets on serum IgG concentration. Jamroz et al (2012) also reported a minor reduction in the concentration of IgG as a result of SDPP inclusion in the starter diets of broiler chickens.…”
