“…In the current study, there was no improvement in fibre digestibility based on change in cellulase‐specific activity but the complication of gut morphology and its digestive microflora, induced by dietary supplementation of organic acids or probiotics alone or in combination, appears to be reasonable. Improvements in digestibility depend on the type and concentration of the acids and the bacterial species that are exposed to the acids (Adil et al., ; Khan & Iqbal, ). Slight changes in digestibility, only for fibre utilization, might be due to inappropriate parameters introduced by the above factors.…”

A feeding trial was conducted to determine the effect of organic acids or probiotics alone or in combination on growth performance, nutrient digestibility, enzyme activity, intestinal morphology and gut microflora in broiler chickens (Ross308). A completely randomized design was used, with 1,440 broiler chicks across four treatments and five replications of 72 chicks each. The chicks in the control treatment were fed on a control diet (CD), whereas for the other treatment groups, the CD was supplemented with 0.2 g/kg organic acids (CDOA), probiotics (CDP) or a combination of organic acids and probiotics (CDOAP). All the chicks were fed ad libitum during the feeding trial throughout 35 days. A total of 20 chicks were randomly allotted to individual metabolic cages to measure the nutrient digestibility (35-42 days) and the digestive enzyme activities (42 days). The intestinal morphology and gut microflora of 80 chicks were examined at the end of experiment. There were no significant (p > .05) differences in the feed intake, body weight gain or feed conversion ratio of the chicks across the four dietary treatments. The crude fibre digestibility was significantly increased in chicks fed on CDOA or CDOAP relative to CD (p < .05). Nutrient utilization, in terms of digestive enzyme activities and excreta thermal property, was unchanged by any supplementation. The chicks fed on the CDOAP had significantly higher duodenal villi height and crypt depth than the chicks fed on CDOA (p < .05). This dietary treatment dramatically improved gut microflora by decreasing the population of Escherichia coli and increasing the Lactobacillus spp.:E. coli ratio. Based on our investigations, supplementation of organic acids and probiotics in chick diets can increase the ability to digest crude fibre and villus height and decrease intestinal E. coli without impairing growth performance.

“…They are either simple mono-carboxylic acids such as formic, acetic, propionic and butyric acids or carboxylic acids consisting hydroxyl group including tartaric, malic, citric and lactic acids or carboxylic acids with double bonds like sorbic and fumaric acids. 30 The content of different organic acids in L. sulphureus has been investigated which is summarized in Table 3.…”

“…Potential alternatives, such as canola meal (CM), have been explored although their use has been limited by the high fibre content and low feeding value compared with soybean meal (SBM) (Wickramasuriya et al, 2015;Ivarsson & Wall, 2017). Nevertheless, the inclusion of enzymes and organic acids, such as humic acids, has been observed to improve the digestibility of poor protein sources such as CM, promoting the effective release of nutrients and other elements that influences the general health of chickens (Luckstadt & Mellor, 2011;Khan & Iqbal, 2015).…”

The objective of the study was to investigate the effects of dietary inclusion of humic acid and enzymes on bone development, histomorphology of internal organs and the incidence of rickets in broiler chickens fed canola-based diets. In the study, Cobb 500 broiler chicks were used and the following five dietary treatments were administered: control (commercial diet); CM (17.5% canola meal inclusion); CMEnz (17.5% CM inclusion + 0.3g/kg Axtra XAP); CMPh (17.5% CM inclusion + 1.5% potassium humate (PH)); and CMEnzPh (17.5% CM inclusion + 1.5% PH + 0.3g/kg Axtra XAP). These diets were formulated and randomly allocated to 20 pens (experimental units), each housing 11 birds. The birds were phase fed, with the starter diet being given to all birds from day 1 to day 14. During the grower (days 15-28) and finisher phases (days 29-42) birds were fed the experimental diets. Diet differed significantly across all treatments on latency-to-lie (LTL) test. Broilers fed CMEnz had the lowest standing persistence (2.88 ± 2.69 min) and those on CMEnzPh had the highest (11.19 ± 2.69 min), followed by those offered the control diet (9.05 ± 2.69 min). Gross lesion analysis displayed high prevalence of rickets in boilers fed CMEnz diet compared with all other dietary treatments. Intestinal morphometric parameters demonstrated some dietary differences in the height and width of the intestinal villi and intestinal crypts. In conclusion, inclusion of humic acid in canola-based diets appeared to positively influence digestion and assimilation dynamics that were consequential to the improvement in bone and immune development in broilers. ______________________________________________________________________________________
