“…Different strains that have been reported in the SSF of palm kernel cake include A. niger (Ong et al., 2004, Iluyemi et al., 2006, Oliveira et al., 2018), Aspergillus wentii (Muangkeow and Chinajariyawong, 2013), Sclerotium rolfsii, Trichoderma spp. (Iluyemi et al., 2006), Paenibacillus polymyxa and Paenibacillus curdlanolyticus (Alshelmani et al., 2014, Alshelmani et al., 2016).…”

“…The reduction in NDF, ADF, crude fibre, hemicellulose and cellulose content may be related to the background of these bacterial cultures as they are capable of producing different types of cellulolytic and hemicellulolytic enzymes such as cellulase, xylanase and mannanase. Solid-state fermentation using A. niger , A. oryzae and Aspergillus awamori reduced the crude fat content of palm kernel cake in relation to its unfermented form (Oliveira et al., 2018). This may be due to lipid hydrolysis catalyzed by lipase produced by the fungi during the SSF process.…”

Solid-state fermented plant protein sources in the diets of broiler chickens: A review

et al. 2019

Protein sources are the second most important component in poultry diets. Due to the fluctuation in price of soybean meal (SBM) and persistent increase in feed prices, nutritionists have been exploring alternative protein sources. Replacement of SBM with alternative protein sources in poultry diets could reduce human-livestock competition for soybean and support the production of more animal protein. However, the use of alternative protein sources is limited to low inclusion due to the presence of anti-nutritional factors (ANF) such as glucosinolates (rapeseed meal), gossypol (cottonseed meal), non-starch polysaccharides (NSP) in lupin flour, high fibre (palm kernel cake), total phenolic contents and phytic acid (canola meal) known to impair animal performance, nutrient digestibility and feed utilization. As a processing technique, solid-state fermentation (SSF) has been researched for a long time in the food industry. An important objective of SSF is the production of enzymes, organic acids and other metabolites of economic importance. In recent times, SSF has been employed to enhance nutrient bioavailability, inhibit gut pathogenic bacteria and reduce ANF in plant protein sources resulting in improved nutrient digestibility, thereby improving performance and gut health of broiler chickens. Unlike pigs, there is still a dearth of information on feeding solid-state fermented feed ingredients to broiler chickens. This review aims to describe the nutritional value of the solid-state fermented products of rapeseed meal, canola meal, cottonseed meal, palm kernel cake and lupin flour on performance and intestinal health of broiler chickens.

“…ixoforming is to cool and solidify the semisolid billet obtained by special processes such as stirring, then cut the material according to the required size, then reheat it to the semisolid temperature, and then place it in the mold cavity for forming. e heating and conveying of semisolid metal blanks are very convenient, the forming process is easy to control, and it is convenient to realize automated production [11]. At present, most processes use thixoforming.…”

Solid-state processing of metal material is a very complex physical and chemical process, which is coupled by a series of variations including heat transfer, momentum transfer, mass transfer, and phase change. Applying three-dimensional (3D) finite element numerical method to the simulation of solid-state processing can perform analysis of metal material’s forging processes before production trial production, can obtain their relevant information such as material flow law, temperature field, and strain field under the minimum physical test conditions, thereby predicting metal material’s forming defects and improving their forging quality. On the basis of summarizing and analyzing previous research works, this paper expounded the current status and significance of solid-state processing of metal materials, elaborated the development background, current status, and future challenges of 3D finite element numerical simulation, introduced the discrimination method and free surface solution method of numerical simulation calculation, conducted finite element model’s geometric assumptions, material selection, element division, model establishment, parameter selection, and initial and boundary condition determination, and simulated and analyzed rheological casting, remelting heating, thixoforming, and rotary piercing processes of metal materials. The results show that the 3D finite element numerical method can not only simulate various processes of flow field, temperature field, stress field, and microstructure in solid-state processing but also can provide a reliable basis for effectively obtaining a reasonable description and finding a more optimized design plan for metal material processing in a short time, which plays an important role in understanding and analyzing solid metal forming process, controlling and optimizing process parameters, guiding and mastering rheological casting, and secondary heating and rotary piercing of metal materials.
