Noticeable mould growth is estimated to reduce feeding value by a minimum of 10 per cent. As mould growth increases, greater loss of nutrients occurs. If a kernel of grain is completely covered with mould, less than five per cent of its original energy is present. Thiamin and vitamin E can also be destroyed by moulds. Some management practices can reduce mould growth.
Damaged kernels mould easily.
Therefore, reducing insect damage, using proper settings on the combine, and harvesting as soon as the grain is mature will help to reduce mould growth. Quick drying and ensuring moisture content is less than 15 per cent in stored grains also inhibit mould growth. There are several commercially prepared preservatives that help to prevent mould. Ammonia can also be used to preserve high moisture hays. Feeding Mouldy Forages and Grains Avoid feeding mouldy feed to young, pregnant or lactating animals.
