“…In addition, it was reported that the effect of anti-nutrients was able to decrease intestinal villi height and increase crypt depth(Erdaw and Beyene, 2018) Rocha et al (2014). andNorozi et al (2022) stated that broiler chicken fed a diet high in trypsin inhibitors impaired pancreatic function and intestinal integrity including shortening and destruction of intestinal microvilli. Thus, a lower villus decreases the capacity for nutrient absorption, which eventually has an impact on animal performance.…”

Hemp seed meals contain high protein and unsaturated fatty acids which have the potential as a substitute for soybean meal and yield eggs rich in unsaturated fatty acids. Therefore, the study aimed to evaluate the impact of dietary hemp seed meal as a substitute for soybean meal protein on productive performances, egg quality, and yolk fatty acid composition. A total of 120 Lohmann Brown laying hens aged 50 weeks were separated into 4 groups and 10 repetitions with 3 birds each. Birds received treatment without hemp seed meal (control group), or soybean meal substituted with 4%, 8%, and 12% hemp seed meal. Dietary 4% hemp seed meal significantly increased (p < 0.05) feed efficiency and egg production compared to the 8% and 12% hemp seed meal group. Meanwhile, feed intake, egg weight, body weight loss, egg shape index, albumen index, albumen weight, Haugh unit, yolk weight, yolk index, and eggshell thickness had no significant influence (p > 0.05). However, dietary 8% and 12% hemp seed meal significantly increased (p < 0.05) eggshell weight and yolk color score compared to the control and 4% hemp seed meal group. There was a significant increase (p < 0.05) in omega-3 fatty acid levels and a significant decrease in yolk omega-6 to omega-3 fatty acids ratio with an increase in dietary hemp seed meal. It concluded that dietary 4% hemp seed meal as soybean meal substitution was able to increase egg production, and feed efficiency compared to the level of 8% and 12% hemp seed meal. Increasing dietary levels of hemp seed meal increased eggshell weight, yolk color, and omega-3 fatty acids content, and decreased the omega-6 to omega-3 fatty acids ratio.

“…Consistent with these results, in this study, we found that ESBM increased the V/C and reduced the CD of the jejunum and duodenum in broilers. These effects might be attributed to the breakdown of antinutritional factors such as glycinin and β-conglycinin in SBM, which were demonstrated to decrease VH, increase CD and reduce the VH to CD ratio, thus having negative effects on the intestinal structure and impairing nutrient digestion and assimilating [31][32][33]. Another explanation may be that compared to SBM, ESBM had a higher level of small peptides after an in vitro enzymolytic hydrolysis and fermentation.…”

Objective: The objective of this study was to investigate the effect of supplementation with enzymolytic soybean meal (ESBM) on broilers fed low crude protein (CP) diets.Methods: A total of 360 one-day-old broilers were randomly assigned to six treatments with 6 replicates per treatment and 10 chicks per replicate for a period of 42 days. Chicks were fed a basal standard high-CP diet as a positive control (PC), a low-CP diet (reducing 10 g/kg CP from the PC) as a negative control (NC), or an NC + 0.5%, 1.0%, 1.5%, or 2.0% ESBM diet.Results: Compared to chicks fed the PC, chicks fed the NC had a decreased body weight gain (BWG, p<0.05) from 1 to 42 days, but supplementation with 2.0% ESBM restored BWG (p<0.05) and even linearly improved the feed conversion rate (FCR, p<0.05). Digestibility of CP and ether extract was increased (p<0.05) in chicks fed a 1.0% ESBM diet compared to the PC. With increasing levels of ESBM, nitrogen (N) excretion decreased (p<0.05). The addition of ESBM to the diet did not affect (p>0.05) serum concentrations of total protein, albumin and total cholesterol but led to a descending trend in triglycerides and an ascending trend in calcium and urea N at 42 days (p<0.10). There were no differences (p>0.05) in villus height (VH), crypt depth (CD), and VH/CD (V/C) of the duodenum and jejunum between the PC and NC at both 21 days and 42 days, while increasing dietary ESBM levels linearly (p<0.05) decreased CD and increased V/C of the duodenum and jejunum at both 21 days and 42 days.Conclusion: The findings indicated that ESBM could be used in broiler low-CP diets to improve production performance, decrease N excretion, and enhance intestinal health.

“…The intestinal microbes of animals play important roles in nutrient digestion and absorption, immune status and gut homeostasis (Peng et al, 2021;Kogut and Fernández-Miyakawa, 2022;Norozi et al, 2022). The cecum is an ideal habitat for the microbes and has the highest density in the goose gut.…”

The processing of edible mushrooms generates a large amount of mushroom residue. How to handle this mushroom residue in a way that avoids environmental pollution and maximizes effective utilization is a current issue that needs to be explored. This study aimed to investigate the effects of substituting dietary corn with Hypsizygus marmoreus mushroom stem waste (HSW) in the diet of geese. The control group was fed with a basal diet (BD), and the other groups were fed the basal diet to which 12% (HSW12 group), 24% (HSW24 group), or 32% (HSW32 group) of HSW were added to replace the equivalent proportion of corn. The test lasted 28 days. The results showed that the average daily feed intake (ADFI) of the HSW12 and HSW24 groups at 35–49 d, and the HSW12 and HSW32 groups at 35–63 d, was significantly higher compared to the BD group (p<0.05). The average daily gain (ADG) of the HSW12 group was significantly higher than BD at 35–49 d (p<0.05), but there was no significant difference in the feed/gain (F/G) among the groups. The levels of serum total protein (TP), albumin (ALB), globulin (GLOB), glutathione peroxidase (GSH-Px), and catalase (CAT) in HSW24 group were significantly higher than those in the BD group (p<0.05). Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and malondialdehyde (MDA) decreased significantly, and there were no significant differences in carcass traits and meat quality. As 24% HSW supplementation had the best overall effect on the growth performance, serum biochemical indicators, meat quality, and carcass traits of geese, gut microbiota analysis was only performed on this group. The microbiota α-diversity of the cecum and ileum did not differ significantly between the BD and HSW24 groups. Principal coordinate analysis (PCoA) indicated that the difference in the cecum was significant in the β-diversity (p<0.05). Short chain fatty acid-producing bacteria and decomposing protein and carbohydrate bacteria (Prevotella) were enriched in the cecum in the HSW24 group. Gut immune regulating and nutritional bacteria, Lactococcus and Bacillus, respectively, were enriched in the ileum in HSW24 group. Spearman’s analysis indicated that Bacillus, Prevotella, and Clostridium were positively associated with serum protein and lipid metabolism. These results indicate that 24% HSW substitution of corn could improve goose serum ALB and fat metabolism, and increase serum antioxidant capacity, which may becaused by the improvement of goose cecal microbiota.
