Aim: The effects of the inclusion of Aspergillus niger in the diet of Haidong chicks reared in the Qing-Zang high altitude area (China) under hypoxic conditions. Materials and Methods: A total of 720 Haidong chicks were randomly divided into six groups and fed diets supplemented with 0%, 0.5%, 0.75%, 1.0%, 1.25%, and 1.5% of A. niger to determine blood parameters, intestinal morphology, and gut microflora in Haidong chicks reared in a high altitude environment. Results: Packed cell volume (PCV), red blood cell (RBC) count, white blood cell count, and hemoglobin concentration increased in the groups fed diets containing A. niger. The administration of A. niger in 1.0% and 1.25% significantly decreased the concentration of Escherichia coli in the cecum, while the concentration of Bifidobacterium and Lactobacillus in the cecum and ileum was increased in the treated groups. When compared to the control groups, villi height, crypt depth, and goblet cell density in the intestine was raised, in general, in the groups treated with A. niger. Conclusion: These findings suggest that 1.25% A. niger as dietary supplement may improve the resistance to ascites among birds reared under hypoxic conditions.

“…In the duodenal portion, we see a significant difference for CD when the levels of 0.75 and 1.5% of buriti oil in the diet were inserted, when higher values were compared to the group that did not receive the treatment. Structures such as villi, crypts and mucosal thickness can be altered by diet composition (Mirzaie et al, 2020). The cells that make up the intestinal crypts accumulate and increase the size of the villi, thus increasing the absorption area.…”

This study aimed to evaluate the productive performance, carcass yield, and intestinal morphometry of broiler chickens subjected to diets with the inclusion of buriti oil. Buriti oil is an energy food that can be used in chicken feed to replace soybean oil, which has a high cost in production, also has its anti-inflammatory, antioxidant, and antimicrobial properties, which can provide benefits in chicken feed. 180 male broilers of the Ross lineage were used, distributed in a completely randomized design with 3 treatments and 6 replicates of 10 birds per experimental unit. The experimental phase took place from 14 to 28 days and levels 0; 0.75 and 1.50% of buriti oil were added to the corn and soybean-based feed. It can be inferred that the buriti oil-based diets in the diet with insertion of levels of 0%, 0.75% and 1.50% did not differ significantly for the productive performance variables, but in relation to the productive yield there was a significant difference for carcass yield accompanied by greater disposition of abdominal fat, thigh and heart fat, a common effect in the use of oils. Although no statistical differences were observed for most of the variables in the assessment of intestinal morphometry, there was an increase in the crypt depth of the duodenum and ileum and an increase in the muscle layer of the duodenum and jejunum, which may have been caused by some injury to the intestine and not by direct effect of buriti oil. In the other variables there was no difference between treatments and it is concluded that buriti oil did not harm the performance, yield and intestinal morphometry of broiler chickens from 14 to 28 days of age.

“…Other studies found improvements in gut morphology when microalgae were incorporated into chicken feed. Broilers fed a basal diet enriched with Chlorella by-products at 1% ( Mirzaie et al, 2020 ) or 2.5, 5, and 7.5% ( Kang et al, 2017 ) were found to have greater jejunum villi height and crypt depth. However, Mirzaie and colleagues observed no significant difference in the intestinal histomorphometry in birds fed diets containing 2% Chlorella by-products ( Mirzaie et al, 2020 ).…”

However, Mirzaie and colleagues observed no significant difference in the intestinal histomorphometry in birds fed diets containing 2% Chlorella by-products ( Mirzaie et al, 2020 ). Combining the results of this study with those of previous studies, it appears that the effects of microalgae on intestinal histomorphometry depend on the type and content of microalgae.…”
