Rice by-products: their use for feeding weaning piglets

Of the total rice production, about 70% is used for human consumption while waste from the milling industry, including rice husks, rice bran, and broken rice, can be used in animal feed.

Broken rice (BR) is obtained during the sieving process. It consists of broken and malformed grains which correspond to 14% of the total grain. Broken rice has been used as a great alternative to corn in animal feed due to its similar  metabolizable energy and crude protein values.(Nepomuceno et al, 2011;  Che et al., 2012).

However, BR has a lower fat content and a higher starch percentage than corn (Rostagno et al., 2017) and contains a very low concentration of fiber (Che et al. , 2012).

Some advantages of replacing corn with rice co-products relate to the low levels of mycotoxins in the grain. Due to the fact that corn tends to be affected with high contamination, predominantly with aflatoxins.

Rice and corn co-products have shown similar effects on animal yield, but rice may induce prebiotic effects and increase serum IgA concentrations, indicating a better immune response (Henderson et al., 2012).
