Comparison of spray‐dried egg and albumen powder with conventional animal protein sources as feed ingredients in diets fed to weaned pigs

Abstract

We evaluated the apparent (AID) and standardized ileal digestibility (SID) of amino acids (AA) in spray-dried egg (SPE) and albumen powder (AP) compared with spray-dried porcine plasma (SDPP), dried porcine solubles (DPS) and fish meal (FM). Additionally, the effects of these egg byproducts as a replacement for conventional animal proteins on the performance and nutrient digestibility of piglets were studied. In Exp. 1, six barrows fitted with ileal T-cannulas were allotted to a 6 × 6 Latin Square design and fed six diets. The AID and SID of AA were generally higher in AP and FM (P < 0.01) than in the other protein sources. In Exp. 2, 150 piglets weaned at 21 days, were fed diets containing the five protein sources for 3 weeks. Weight gain of piglets fed SDPP was the highest among the treatments. Dry matter and protein digestibility for pigs offered SDPP were higher (P < 0.01) than those offered FM and DPS. AP decreased (P < 0.05) Escherichia coli counts in the cecum. DPS decreased (P < 0.05) serum diamine oxidase compared with SPE. In conclusion, AP and SPE are competitive with traditional animal protein sources and can be successfully fed to piglets without compromising performance.

Comprehensive overview of the quality of plant‐ And animal‐sourced proteins based on the digestible indispensable amino acid score

“…Variations observed within each DIAAS dataset can also originate from the conditions in which the intervention diets were provided. Firstly, clear dissimilarities can be noted in starting age/ body weight of the growing pigs, varying from 17.8 ± 1.7 kg (Zhang et al, 2015) to 76.2 ± 5.6 kg (Pedersen, Boersma, & Stein, 2007).…”

Effects of partial replacement of fishmeal with blood meal and dried porcine soluble on the growth, body composition and intestinal morphology of Cyprinus carpio

“…DPS can promote the growth of intestinal villi and improve the performance of weaned piglets (Gao, Ma, & Ji, ), although recent studies suggest replacement of FM by DPS and fermented soybean meal has no significant effect on the intestinal morphology of weaned piglets (Liu, Wang, & Wang, ). Zhang, Piao, and Ma () showed that DPS can reduce serum diamine oxidase in weaned piglets and maintains the intestinal barrier. The results of the above studies were different from the present study, which may be due to different study subjects and/or substitution ratios.…”

Digestibilidade aparente e valor energético do ovo integral em pó para frangos de corte

“…Os coeficientes de digestibilidade do ovo em pó integral e proteína bruta foram de 72,17% e 86,81% respectivamente (Tabela 4). Zhang et al (2015) realizaram uma comparação de pó de albúmen e ovo seco em pó com fontes convencionais de proteína animal em dietas para suínos e concluiu que o pó de albúmen e ovo seco em pó são opções competitivas com fontes tradicionais de proteína animal e podendo ser utilizada com sucesso na alimentação de leitões sem comprometer o seu desempenho, encontrando os valores de digestibilidade ileal aparente de proteína bruta e aminoácidos na sequência de pó de albúmen (82,1%), e ovo seco em pó (70,0%).…”

“…Fonte: Os autores Os dados da Tabela 4 refletem a alta digestibilidade que este produto possui, mesmo contendo casca de ovos como parte de sua composição (sendo este o motivo de o CD total do ovo em pó ser inferior ao CD da proteína bruta contida nele). Ainda, Zhang et al (2015) avaliaram a digestibilidade ileal padronizada de proteína bruta e aminoácidos, sendo do albúmen 92,0%, e ovo seco em pó de 81,0%, e digestibilidade aparente do trato total de matéria seca no pó de albúmen de 82,2%, enquanto no ovo seco em pó foi de 83,9%. Para proteína bruta, no pó e albúmen 73,2%; e no ovo seco em pó (42,8%).…”
