“…On the other hand, broilers that received fermented cassava at 21–30, 31–40, 41–50, and > 50 % had significantly poor ADG, as confirmed by Ogbuewu and Mbajiorgu ( 2022 ) that broilers fed moderate to high levels of processed cassava diets. This could be due to anti-nutritional factors (Omede et al 2017 ; Ogbuewu and Mbajiorgu 2023a ) contained present in fermented cassava-based diets, exceeding the tolerance level of the broiler chickens.…”

“…Cassava is non-seasonal and drought-resistant plant and yields about 5 to 10 times more calories per unit area of land than maize (Ogbuewu and Mbajiorgu 2023a ). It belongs to the kingdom Plantae and the family Euphorbiaceae.…”

“…It is categorised as either a bitter or sweet variety. According to Ogbuewu and Mbajiorgu ( 2023a ), cassava root, cassava starch residue, peels, pulps, chips, and root sievate were classified as sources of energy in chicken feed and are known as co-energy products, whereas cassava leaf is used as a source of dietary protein. The use of cassava as a co-energy product in animal nutrition has been advocated primarily because it is readily available and less expensive than maize.…”

“…The fibrous nature of cassava by-products may limit their digestion and uptake as the chicken gut was not designed to handle fibrous diets. The application of biotechnology to enhance protein biomass and fibre digestion and reduce anti-nutrient agents in cassava has been advocated (Aladi 2016 ; Chukwukaelo et al 2018 ; Ogbuewu and Mbajiorgu 2023a ). Fermented cassava is rich in nutrients and unknown growth factors produced by microbes during the fermentation process (Chukwukaelo et al 2018 ).…”

“…As a result, fermented cassava can be an excellent source of energy for broiler chickens. A recent review by Ogbuewu and Mbajiorgu ( 2023a ) revealed variable performance results in avian species offered fermented cassava.…”

The effects of dietary fermented cassava on the blood constituents and production parameters of broiler chickens have been reported with variable outcomes. Therefore, this investigation aimed to explore the impacts of dietary fermented cassava on growth traits, blood constituents, visceral organ, and carcass characteristics of broiler chickens. Four databases were searched for studies that assessed responses of broiler chickens dietary fermented cassava. Eleven articles were used for the investigation, and data generated were analysed using OpenMEE software. A random effects model was used, and effect sizes were presented as standardised mean difference (SMD) at a 95 % confidence interval (CI). Sources of heterogeneity were evaluated using the following modifiers: broiler strain used, cassava form, feeding duration, type of microbes used for the fermentation, and inclusion level of cassava. Results indicate that fermented cassava-based diets increased feed intake (SMD = 0.38; 95 % CI: 0.11, 0.65; P = 0.006), feed conversion ratio (SMD = 1.26; 95 % CI: 0.91, 1.61; P < 0.001), white blood cells (SMD = 1.26; 95 % CI: 0.54, 1.98; P < 0.001), total serum protein (SMD = 1.23; 95 % CI: 0.41, 2.05; P = 0.003), serum cholesterol (SMD = 0.43; 95 % CI: 0.01, 0.85; P = 0.050), serum creatinine (SMD = 2.53; 95 % CI: 0.53, 4.53; P = 0.013), and serum uric acid (SMD = 4.33; 95 % CI: 6.25, 2.41; P < 0.001), but lowered average daily gain and carcass yield, taking heterogeneity into account. Results reveal that studied modifiers were responsible for the inconsistent results among authors. In conclusion, dietary fermented cassava negatively influenced carcass yield, growth performance, and aspects of blood indices of broiler chickens, but did not affect abdominal fat content, visceral organ weights, and cut-part weights. However, more innovative research is needed to improve the feeding quality of cassava using other biotechnological tools in order to maximise its potential as an energy source in broiler chickens.
