Molasses are often used to enhance palatability. Both peanut skins and bakery waste can be difficult to feed. Peanut skins are fluffy and nutrient content varies with amount of nuts present. Bakery waste can be packaged in plastic. Feeding both feeds might require some hand feeding.
Peanut skins have some oil that can be an energy source for cattle as does bakery waste.
The tannin content reduces protein digestibility of the skins. Bakery waste can also supply starch and replace some grains in the ration. Soybean hulls or flakes are sources of digestible fiber. They can replace starch or grains in dairy rations. They should not be used to replace forages unless excess fiber is being fed.
