Fucoidan can improve the antioxidant capacity of liver in weaned piglets
Keywords:
Recently, the Pig Nutrition and Feed Innovation Team of the Feed Institute of the Chinese Academy of Agricultural Sciences found that adding fucoidan to the diet can effectively alleviate liver oxidative damage caused by weaning stress in underweight piglets, providing fucoidan with the ability to improve animal liver health. theoretical basis. Relevant research results were published in"Antioxidants".
In modern intensive breeding, the early weaning strategy of high-yielding sows can effectively improve economic benefits, but it will lead to a significant increase in the number of piglets with low birth weight and retarded growth during lactation. These piglets are more susceptible to oxidative stress and liver damage caused by weaning, resulting in periodic growth stagnation or even death of piglets.
Therefore, under the background of the antibiotic ban, it is urgent to find green feed additives that can effectively improve animal health. This study established a piglet liver oxidative damage model and found that adding fucoidan to the diet can significantly improve the growth performance and antioxidant function of underweight piglets after weaning.
Further studies have shown that fucoidan can enhance the liver antioxidant capacity of piglets and protect the liver from oxidative stress damage by regulating the Keap1/Nrf2 signaling pathway and mitochondrial function in piglet livers.
This study provides a new nutritional intervention strategy for improving the antioxidant capacity of weaned piglets and provides theoretical support for the development and application of fucoidan as a new green feed additive.
