“…Feed producers have been improving their technical potential of heating and pressure-thermal processing of imported and domestic soybean seeds [6][7][8][9][10][11]. Processing of soybean seeds for consumption results in multiple products that can be used in animal nutrition, i.e., soybean meal (from dehulled seeds, with different particle size, extracted, expelled), soybean expeller cake, soybean oil, extruded full-fat soybean, isolated soybean protein, and soybean hull [1,8,9,11,12]. All these products differ in terms of the content of nutrients and thus can be fed to different species of animals [11,13,14].…”

The study aimed to determine the overall effect of replacing soybean meal completely with soybean expeller cake or extruded full-fat soybean in feed rations for broiler chickens on their carcass composition and meat quality. The experiment involved one hundred and twenty Ross 308 broiler chickens randomly allocated to three equinumerous groups (SBM, SEC, EFS). Each group was divided into five subgroups—each consisting of eight birds of both sexes (1:1). From Day 1 to Day 21 of life the birds were fed with loose starter rations, and from Day 22 to Day 42 they were fed grower rations based on a wheat meal, protein products and mineral and vitamin admixtures. The experimental factor was a protein raw material comprising: SBM group—soybean meal from GM (genetically modified) seeds, SEC—soybean expeller cake from n-GM seeds, and EFS—extruded full-fat soybean from n-GM seeds. The experimental diets were isocaloric and isonitrogenous. It was demonstrated that replacing soybean meal with SEC or EFS in feed rations for broiler chickens led to a significant (p < 0.05) weight gain on Day 42 of rearing by 4.57% and 2.88%, respectively. The chickens fed diets with EFS had worse (more than 4.14%) feed conversion rate (FCR) in comparison to the others (p < 0.05). Broiler chickens from the SBM and SEC groups showed a higher share of breast and leg muscles (by 4.74% and 7.54%) and a lower share of abdominal fat (by 31.1%) and skin with subcutaneous fat (by 18.8% and 13.4%) in comparison with birds from the EFS group (p < 0.05). The highest content of intramuscular fat with the best fatty acids profile was determined in the muscles of birds fed with diets containing EFS, while the muscles of chickens receiving SEC scored the highest. The results provide grounds for recommending SEC in broiler chicken nutrition as it allowed for obtaining the best production and slaughter results, whereas—from the point of view of the human diet—EFS should be recommended since it best modified the lipid fraction of muscles.

“…This outcome is strongly related to the digestive organs and diet of the laying hens (Xu & Ding, 2012). To achieve high and consistent production, the hens are fed appropriate protein nutrients, vitamins, calcium and other nutrients beginning with the laying stage (Marx et al, 2021), which supplied good nutrition for the birds’ intestinal fungal community. After a time of adaptation, the microbial community in the intestines of chickens eventually achieved a stable state, with Candida , Pezizomycetes ‐associated genus and Kodamaea accounting for about half of the total, potentially reducing the fungal variety of chicken faeces.…”

Aims Cattle and poultry manure composting are often applied on agricultural lands but the fungal community composition before and after application in soils is still unclear. This study describes soil fungal diversity after manure applications contribute to the correct resource use of livestock and poultry manures. Methods and Results Fresh manure samples were obtained from 10 beef cow farms and 12 egg‐laying poultry farms at five distinct phases of rearing. Surface soil samples were collected from vegetable plots within the farms after manure application at 15, 30 and 45 t hm−2. Using high‐throughput sequencing techniques, the ITS region was used to describe soil fungus populations. The fungal OTUs, Chao1 and ACE of cattle manure were relatively higher in the fattening stage (>12 months), the OTUs and ACE of chicken manure were the highest in the initial laying stage (16–24 weeks). The fungal diversity indices of vegetable soils had no linear change after cow or chicken manure application compared with the control. Ascomycota (84.7% of total sequences), Neocallimastigomycota (9.69%) and Basidiomycota (4.6%) were the dominant phyla in cattle manure. Ascomycota (88.9%) also predominated in chicken manure followed by Basidiomycota (8.9%). Following both cattle and chicken manure applications, the abundance of Ascomycota decreased, whereas Basidiomycota and Chytridiomycota increased in the soils. None of the dominant genus increased or decreased linearly with the increase of cattle and chicken composting application rate. The fungal‐dominant genera of the soils with and without manure composting application were mostly affected by soil pH and EC than manure. Pearson’s correlation analysis revealed that organic matter, Cu and Hg contents were strongly linked to the fungal diversity and the abundance of specific taxa in cattle manure. In chicken manure, OM, TN and Zn were major factors controlling the fungal diversity and community composition. Soil pH, EC and Cu, Zn, Cd, Hg and As content had pronounced effects on the beneficial and pathogenic genus in soil with and without manure composting. Beneficial fungal genus such as Aspergillus, Plectosphaerella, Acremonium, Meyerozyma and fungal pathogenic such as Fusarium, Cladosporium, Verticillium were sensitive to properties (EC, pH, OM) and heavy metals (Cu, Zn, Hg) contents of the environment relatively. This study can serve as an applicable contribution helping in farms management (especially to cattle and poultry breeding) and improving their resource use of livestock and poultry manures. Conclusions Soil heterogeneity rather than manure determines fungal communities in the vegetable fields, but we can encourage the sensible use of cattle and chicken manures in agroecosystems. Significance and Impact of the study This study will help farmers regulate the dosage of feed components which can increase the number of beneficial fungal genus or reduce the number of pathogenic fungal genus, improve their resource use of livestock and poultry manures and encourage t...

“…Also, protein digestibility was increased for larger particle size SBM ( Pacheco et al, 2013 ). From 0 to 42 d, Marx et al (2021) fed mash diets to broilers differing only in SBM particle size (625, 775, 1,053, or 1,406 μm), and observed that FCR linearly decreased as SBM particle size increased, but particle size did not influence feed intake. It was also observed that smaller or coarser particle size SBM resulted in similar CP digestibility and digestible energy ( Marx et al, 2021 ).…”

“…Thus, increasing the particle size of SBM may not only reduce energy needed during feed manufacturing but may also improve the growth performance and nutrient utilization of poultry. Because SBM is one of the main ingredients included in poultry diets and only a small number of studies have been conducted to evaluate SBM particle size, it is desirable to conduct further research ( Pacheco et al, 2013 ; Marx et al, 2021 ; Lyons et al, 2023 ). The objectives of this study were to determine the TME n and standardized amino acid ( AA ) digestibility of SBM varying in particle sizes utilizing the precision-fed rooster assay and to evaluate what effect SBM particle size may have on growth performance and nutrient digestibility in young broiler chicks.…”
