Summary: This study measured the energy values of soybean meal and investigated the effects of specific enzyme supplementation on the growth performance and intestinal digestion properties of broiler chickens. The results showed that the addition of β-mannanase and protease improved body weight gain and increased the content of certain digestive enzymes. Furthermore, β-mannanase supplementation enhanced villus height and promoted the degradation of oligosaccharides. Overall, the study demonstrated that enzyme supplementation, particularly β-mannanase, improved intestinal digestion properties and increased the energy values of the feed.

Summary: Over the years, there has been a need for alternative protein sources in broiler feed due to the increase in price of traditional sources. Sunflower meal (SFM), a by-product from the oil processing industry, is a cost-effective option. However, its inclusion levels have been limited due to the presence of anti-nutritional compounds. This study explores the use of multi-enzymes to increase SFM inclusion levels and improve broiler performance.

Summary: The accurate estimation of the apparent metabolizable energy (AME) content of feed ingredients is crucial for poultry feed formulation. The current AME values of protein-source ingredients are determined using older broilers, ignoring the effects of broiler age. This study examined the effects of broiler age on the AMEn of soybean meal (SBM) and canola meal (CM), and found that age has a marked effect on the AMEn of these ingredients.

Summary: The animal production industry is facing the challenge of developing innovative methods to meet future environmental and economic needs. This research evaluated the energy values of two feed ingredients and their effects on broiler chickens and pigs. The results showed that these feed ingredients have substantial energy values.

Summary: This study evaluated the effects of feeding low-bush wild blueberry (LBP) and organic American cranberry (CRP) pomaces without or with multien-zyme supplement (ENZ) on growth performance, organ weight, and plasma metabolites in broiler chickens. The results showed that ENZ had no significant effects on overall growth performance and organ weights, but it had the potential to modulate the metabolism of pomace-fed broilers. LBP increased body weight during the starter phase, while CRP increased body weight during the grower phase.

Summary: Two studies were conducted with broiler chickens to determine the ileal digestible energy (IDE), ME, and MEn in copra meal (CM) and cornstarch. The results showed that inclusion of CM in diets may reduce the digestibility of GE, whereas the digestibility and utilization of GE may increase when adding cornstarch into diets for broiler chickens.

Summary: This study aimed to investigate the effects of partially replacing soybean meal with fermented distillers grains with solubles (DDGS) on growth performance, blood parameters, meat quality, intestinal microflora, and immune response in broilers. The results showed that the partial replacement of soybean meal with fermented DDGS had a positive effect on feed conversion ratio without affecting growth performance, and combining fermented DDGS with multienzymes improved immune and gut health status.

Summary: This review highlights the complexity of arabinoxylan in corn and the importance of debranching enzymes in enhancing fiber degradability. The unique structure of arabinoxylan in corn, with a high level of substituents, results in significant resistance to xylanase attack. Debranching enzymes play a crucial role in increasing xylanase access and breaking phenolic linkages, ultimately improving fiber degradability in cereal grains, particularly in corn-based feeds for commercial poultry diets.

Summary: Two studies were conducted to evaluate the effects of autoclaving soybean meal and poultry meal on phosphorus digestion and utilization. The results showed that autoclaving decreased the digestion and retention of dry matter, while increasing the inclusion level of test ingredients increased the intake of digestible and utilizable phosphorus. Autoclaving soybean meal resulted in higher ileal digestibility and retention of phosphorus.

Summary: This study utilized a tailored combinatorial approach to prepare protein supplements from Corn Gluten Meal, by using green solvent for deodorization and enzymatic hydrolysis to enrich lysine content. The alkaline protease from Aspergillus oryzae was found to be the most effective in hydrolyzing CGM, generating peptides with high antioxidant activity. The scalability and market potential of the developed product were demonstrated through sales and cost analysis.

Summary: This study evaluated the digestibility of amino acids and the energy value of carinata meal and canola meal for broilers. The results showed that canola meal is a good source of protein and energy for broilers, while carinata meal may require lysine fortification due to its lower digestibility.

Summary: The study suggests that increasing the substitution rate of guar meal for fish meal in the diet may affect the activity of intestinal digestive enzymes, thus influencing the growth and carcass composition of Labeo rohita. However, growth parameters, feed conversion efficiency, and protein efficiency ratio did not differ significantly among different substitution rates.

Summary: The study found that replacing soybean meal with fermented palm kernel meal as a protein source had positive effects on sex-reversed red tilapia, with the 50% replacement level showing the best results. Solid-state fermentation improved the nutritional values of palm kernel meal, leading to a low-cost diet option for tilapia farming.

Summary: This study evaluated the effectiveness of steam as an additional method for depopulation of laying hens in a cage-free aviary system. The results showed that steam alone or in combination with heat can lead to faster mortality of hens, and the distribution of carcasses varies in different tiers.
