  • Objective: This study aimed to assess the effects of dietary mulberry leaves on the growth, production performance, gut microbiota, and immunological parameters of poultry and livestock. Methods: The PubMed, Embase, and Scopus databases were systematically analyzed to identify pertinent studies up to December 2022. The effects of mulberry leaf diet was assessed using the weighted mean difference, and the 95% confidence interval was calculated using a random-effects model. Results: In total, 18 studies that sampled 2,335 poultry and livestock were selected for analysis. Mulberry leaves improved the average daily gain and reduced the feed/meat ratio in finishing pigs, and the average daily gain and average daily feed intake in chicken. In production performance, mulberry leaves lowered the half carcass weight, slaughter rate, and loin eye area in pigs, and the slaughter rate in chickens. Regarding meat quality in pigs, mulberry leaves reduced the cooked meat percentage, shear force, crude protein, and crude ash, and increased the 24 h pH and water content. In chickens, it increased the drip loss, shear force, 45 min and 24 h pH, crude protein, and crude ash. Mulberry leaves also affect the abundances of gut microbiota, including Bacteroides, Prevotella, Megamonas, Escherichia-Shigella, Butyricicoccus, unclassified Ruminococcaceae, Bifidobacterium, Lactobacillus, and Escherichia coli in poultry and livestock. Mulberry leaves at different doses were associated with changes in antioxidant capacity in chickens, and immune organ indexes in pigs. With respect to egg quality, mulberry leaves at different doses improved the shell strength, yolk color, eggshell thickness, and eggshell weight. However, moderate doses diminished the egg yolk ratio and the egg yolk moisture content. Conclusion: In general, dietary mulberry leaves improved the growth, production performance, and immunological parameters in poultry and livestock, although the effects varied at different doses.

  • Tomato sauce were prepared with five different thickening agents including roux (TR), non-glutinous rice powder (TN), glutinous rice powder (TG), potato starch (TP) and tapioca starch (TT) to examine proximate composition (moisture, carbohydrate, crude protein, crude fat, crude ash, crude ash), calorie, color value, pH, salinity, $^{\circ}Brix$, reducing sugar, viscosity and sensory test (attribute difference, acceptance). The results were as follows: Moisture, carbohydrate content were the lowest while crude fat and calorie were the highest in TR (roux). On the other hand, moisture, carbohydrate content were the highest while crude protein, crude fat and calorie were the lowest in TP (potato starch) and TT (tapioca starch). Using potato starch and tapioca starch are supposed to be prepared low-fat, low-calorie tomato sauce. L value was the highest in TN (non-glutinous rice powder), a value was the highest in TP (potato starch), b values was the highest in TR (roux). pH of tomato sauce showed a range of 5.24 to 5.39. TG (glutinous rice powder) was the highest and TT (tapioca starch) was the lowest in pH. TP (potato starch) was the highest salinity, reducing sugar was the lowest. TG (glutinous rice powder) was the lowest salinity, $^{\circ}Brix$ was the highest. And TR (roux) was the lowest $^{\circ}Brix$, reducing sugar was the highest. In viscosity, TG (glutinous rice powder) was the highest and TT (tapioca starch) was the lowest. The attribute difference test results was the highest in gloss, color intensity, tomato odor, tomato taste, pure taste in TT (tapioca starch) and savory taste, oily taste, thickness, residue was the highest in TR (roux). The preference test results reveal that the appearance, flavor, taste, texture and overall acceptance level was the highest in TP (potato starch) and TT (tapioca starch). The results of this study, tomato sauce prepared potato starch and tapioca starch instead of the traditional roux was higher in sensory acceptability. Recently, people is avoided high-fat and high-calorie foods, and potato starch and tapioca starch are confirmed that the tomato sauce can be made of a low-fat and low-calorie.
