“…Similar results were also observed in a study investigating the effects of MLM supplementation on poultry meat quality (Ding et al, 2021). Similar results were observed in pigs (Liu et al, 2019;Zeng et al, 2019) and rabbits (Wu et al, 2019;Hou et al, 2020) with the addition of MLM. However, the mechanism underlying how mulberry leaf changed the muscle fibre types is unclear.…”

This experiment was conducted to determine the effects of mulberry leaves on performance, carcass characteristics, and meat quality of Japanese quail. A total of 240 one-day-old Japanese quail chicks were randomly allocated to three experimental groups and fed a basal diet (control) and the basal diet plus 50 g/kg and 100 g/kg mulberry leaf meal (MLM) for 42 days. By the end of the study, performance parameters of quail fed the 100 g/kg MLM-supplemented diet were affected negatively. The highest carcass weight and carcass yield levels were exhibited in the control group. In terms of meat quality, the shear force of the breast meat of quail fed the diet with 100 g/kg supplemented MLM was higher than the other groups. The highest L* and hue angle values of breast meat were found in the 50 g/kg MLM group. Released water from the thigh meat in the control group was higher than in the experimental groups. The current study indicates that 50 g/kg MLM can be used easily in quail rations without any negative effects.

“…Previous studies have shown that mulberry leaves affect feed intake and intestinal development in animals, prolong the retention of chyme in the intestinal tract, and increase intestinal weight ( Prasad et al., 2003 ; Simol et al., 2012 ; Hou et al., 2020b ). In our study, DNJ did not greatly affect feed intake, neither did it affected intestinal development or cause chyme accumulation.…”

“…The content of crude protein and carbohydrate in mulberry leaves is significantly higher than those in other green forage and is comparable to that of high-quality legume forage such as alfalfa ( Doran et al., 2007 ). At present, as a feed or feed additive, mulberry leaf has been widely used in the breeding of ruminants, rabbits, and pigs and has been reported to significantly improve the yield and quality of meat and milk ( Chhay et al., 2010 ; Venkatesh Kumar et al., 2015 ; Ma et al., 2017 ; Hou et al., 2020b ).…”

This study was aimed to investigate whether 1-deoxynojirimycin ( DNJ ) affects the digestion system of young geese and assess whether mulberry leaf, which contains this substance, has disadvantages that compromise its value as poultry feed. One hundred and twenty-eight 12-day-old male Wanxi white geese were randomly assigned into 4 treatment groups. The control group was fed an ordinary diet without DNJ. The other groups namely L-DNJ, M-DNJ, and H-DNJ had their basic diets supplemented with 0.05 mg/g, 0.1 mg/g, and 0.15 mg/g DNJ, respectively. The geese were fed for 6 wk, and the apparent digestibility test was conducted in the last week. Intestinal parameters, digestive organs, and enzymes were determined. 16S rRNA gene sequencing was conducted for cecal flora composition. The results revealed that DNJ decreased body and liver weight and increased feed conversion ratio in comparison with the control ( P < 0.05); however, it did not influence the weight and length of the intestine or the pancreas weight. The utilization of organic matter, metabolizable energy, ether extract, acid detergent fiber, and calcium in feed were reduced in the M-DNJ and L-DNJ groups compared with those in the control ( P < 0.05); however, the utilization of crude protein was increased in all DNJ-treated groups ( P < 0.01). In the H-DNJ group, the usage of soluble phosphorus was also increased ( P < 0.05). High-dose DNJ increased the activity of trypsin in the pancreas but reduced those of amylase ( P < 0.05) and lipase ( P > 0.05) in the pancreas and duodenum. The intestinal villi were short, even impaired, in DNJ-treated groups. High-throughput sequencing data revealed that DNJ supplement reduced the α-diversity indices of the cecal microbiota. The principal component analysis further suggested a difference in community structure between the DNJ treatment groups and control. High-dose DNJ increased the relative abundance of Bacteroides , Escherichia-Shigella , and Butyricicoccus but reduced that of unclassified Ruminococcaceae compared with the control ( P < 0.05). In conclusion, changes in the digestive system caused by DNJ seriously affected the metabolism of nutrients in geese and reduced their growth performance. Attention should be paid to the adverse effects of DNJ when using mulberry leaves as poultry feed.

“…For instance, although China is the world's largest mulberry grower, with an annual output of 20 tonnes per ha, its mulberry leaf utilization rate is only 1%-3% . It is mainly used as silkworm feed, while a small amount of mulberry leaf powder is directly added to the feed of domestic animals, such as broilers (Islam et al, 2014), beef cattle (Huyen et al, 2012), meat rabbits (Hou et al, 2020) and meat geese (Wang et al, 2017).…”

Aquaculture, which is one of the primary methods used to generate aquatic products, plays an important role in solving global food shortages and improving physical qualities of humans (Li et al., 2019;Perschbacher, 2015). However, aquaculture production space is constantly decreasing due to advancing global industrialization, resulting in the number of ongoing traditional aquaculture projects being insufficient to meet the rapid growth of human demand for aquatic products (Li et al., 2019). As a result, improving the yield per unit area has come to be considered as an effective means of ensuring an adequate supply of aquatic products (Cressey, 2009). In addition to improving culture modes 2 , developing new growth-promoting and disease-resistant feed is expected to improve aquaculture output.Mulberry (Morus alba) leaves are rich in protein, vitamins and trace elements, which improve the body's immunity, antioxidant capacity, metabolic activities, anti-stress ability and disease resistance (Cai, Mu,
