Mulberry leaf extract contains bioactive substances such as flavonoids, polysaccharides and 1-deoxynojirimycin (DNJ), which exerts its hypoglycemic effect by improving hepatic glucose metabolism, reducing islet oxidative damage, and maintaining β-cell function to promote insulin secretion. Mulberry leaf extract has physiological effects on antioxidant, bacteriostatic and lipid metabolism in animals. It is widely used in livestock, poultry, ruminants and aquaculture to improve the immunity and production performance of animal organisms.
Physiological effects of mulberry leaf extract on animals
1.1 Antioxidant effect
Mulberry leaf flavonoids can remove superoxide ion free radicals in the body, have significant antioxidant effects, and are a natural antioxidant. Mulberry leaf DNJ has strong in vitro total antioxidant capacity and can remove 1-diphenyl-2-trinitrophenylhydrazine (DPPH) and hydroxyl groups.
1.2 Antibacterial effect
The mulberry leaf extract has obvious inhibition and killing effect on Staphylococcus aureus, but has no inhibitory effect on mold.
2.3 Lipid metabolism
Studies have shown that mulberry leaf hexane extract can reduce the degree of lipid digestion in the intestine by inhibiting pancreatic lipase activity and has the potential to regulate lipid metabolism. The possible mechanism of action is that DNJ activates enzymes such as fatty acid β-oxidase, which accelerates lipid metabolism in the body.
2 Application of mulberry leaf extract in animal production
2.1 Application in pig production
The active substance of mulberry leaf extract and mulberry leaf flavonoids can improve the intestinal environment of piglets, reduce the diarrhea rate of piglets, increase the survival rate of piglets, increase daily weight gain, and improve meat quality. .
3.2 Application in poultry production
Mulberry leaf extract active substances DNJ and mulberry leaf polysaccharide can significantly improve egg quality, lower blood sugar and blood lipids, increase egg production rate, and promote broiler growth. Adding mulberry leaf extract to the diet can significantly increase the average daily gain and average daily feed intake of the dwarf yellow chicken, and reduce the feed-to-weight ratio, which can slightly increase the slaughter rate and semi-net sputum rate.
3.3 Application in ruminants
Rumen fermentation produces a large amount of methane, which reduces the efficiency of nutrient use by ruminants, and the emitted gases pollute the atmosphere. Adding mulberry leaf extract can reduce the concentration of NH3-N in vitro, increase the digestibility of dry matter in 48 h, and improve the rumen fermentation mode to some extent.
3.4 Application in aquaculture
Mulberry leaf extract can effectively improve fish glycolipid metabolism, improve immunity and antioxidant capacity, and improve growth performance, so it has important development and utilization value in aquaculture. Adding mulberry leaf extract to juvenile fish feed has no significant effect on its growth performance and body composition. When the content of mulberry leaf extract is less than 3%, the feed utilization rate is improved and the lipid metabolism of juvenile fish is improved. And immune function.
