“…Soluble NSP is known to correlate with high intestinal viscosity and low activity of digestive enzymes on nutrients in the species of European seabass (Dicentrarchus labrax) (Magalhães et al, 2016). Previous researches have also attested to a negative correlation between chyme viscosity and the activity of digestive enzymes in Nile tilapia (Kabir et al, 2020;Tu-Tran et al, 2020), including the activity of chymotrypsin, trypsin, lipase and amylase enzymes (Hassaan et al, 2019). Therefore, these results may explain this study's lower ADC of starch and crude protein in fish-fed the control diet.…”

“…Besides phytate, the dietary fibre fraction of some cereals is rich in nonstarch polysaccharides (NSPs) that are mainly composed of arabinoxylan and β‐glucans (Bach Knudsen, 1997; Englyst et al, 1989). The NSP‐rich diets increase the digesta viscosity and cause a reduction in fish nutrient digestion (Kabir et al, 2020; Magalhães et al, 2016; Tu‐Tran et al, 2020). Therefore, recent studies have attested for the use of exogenous carbohydrases that catalyze the reduction in the molecular weight of polymeric carbohydrates, mainly xylanase and β‐glucanase, in plant‐based diets fed to Nile tilapia (Maas, Deng, et al, 2021).…”

This study aimed to evaluate the effects of supplemental phytase with xylanase and β‐glucanase blend on the apparent digestibility coefficient (ADC) of gross energy and nutrients, including amino acids, minerals, and nitrogen (N) and phosphorus (P) balance in Nile tilapia, Oreochromis niloticus. Diets were elaborated either without enzyme supplementation (control) or supplemented with phytase (PHY), xylanase and β‐glucanase (XB) blend or a combination of phytase plus xylanase and β‐glucanase (PHY+XB) blend. Fish (n = 192; 60 ± 3.4 g) were fed with the experimental diets replicated four times. Compared with the control group, fish‐fed with the PHY+XB diet showed a higher ADC of gross energy and nutrients, including amino acids and minerals. Also, compared to control diet, digestible energy, digestible protein and available P contents were higher in fish‐fed diet PHY+XB by 1.63 MJ kg−1, 7.21 and 4.70 g kg−1 diet respectively. Compared to the control group, fish‐fed diet PHY+XB displayed lower total N and P loss of 17.51 and 10.09 g kg−1 of body weight gain (BWG) respectively. The study findings provided new insight into the nutritive value and ecofriendliness/sustainability of diets associated with exogenous enzymes for tilapia culture.

“…More mesocosm experiments are needed to determine the expected variation between treatment in mesocosms. In literature, for pond experiments, the number of replicates per treatment commonly varies between three (Asaduzzaman et al., 2010; Hari et al., 2006) and six (Kabir et al., 2020).…”

“…In addition, accumulation of organic carbon and nutrients like N and P may occur in intensified fish ponds and eventually lead to pollution when discharged without treatment. By paying attention to the waste composition resulting from feeding during feed formulation, the recycling of nutrients within the pond can be enhanced, which leads to a higher nutrient use efficiency within ponds, reducing nutrient requirments and contributing to circularity (Kabir et al, 2020).…”

Farmed animal production in tropical circular food systems

et al. 2021

In the discourse about the development of farmed animal production (terrestrial livestock production and aquaculture) in the tropics, two important food system outcomes emerge: (1) to supply animal-sourced food (ASF) at a level that suffices healthy future diets, including for poor people, and (2) to contribute to climate change mitigation and minimize pollution with nitrogen and phosphorus. Livestock production and aquaculture contribute to food security directly by increasing producers’ food diversity and availability, but also that of urban consumers, and indirectly through income generation and increased farm resilience. Recently, circularity has come to the fore as an integrated approach to food system development. Circularity has four cornerstones: (1) food crops have highest priority (which implies no food-feed competition), (2) avoid losses, (3) recycle waste and (4) use animals to unlock biomass that humans cannot eat. In this review, the role of farmed animals in circular food systems in the tropics is presented in four case studies and the impacts of circularity on food security and environmental impact mitigation are discussed. The cases are ruminants in grazing systems in West Africa and in Colombia, fish in pond aquaculture in general, and land-limited dairy production in Indonesia. Additionally, options for novel protein sources for use in livestock and fish feeding are presented. It is concluded that farmed animals are important in circular food systems because of their use of land unsuited for crop production, their upgrading of crop residues, and their supply of manure to crop production. Nevertheless, the increasing demand for ASF puts pressure on important characteristics of circularity, such as minimizing food-feed competition, maximization of use of waste streams in feed, and the value of manure for fertilization. Hence, in line with conclusions for Western countries, maximum circularity and sustainability of food systems can only be achieved by optimizing the population size of animals. Thus, a sustainable contribution of ASF production to global food security is complex and in not only a technical matter or outcome of an economic process balancing supply and demand. It requires governance for which public, private, and social actors need to partner.
