Megalac is a combination of palm fatty acids and calcium.
The calcium protects the fatty acids from breaking down in the rumen, so they pass intact to the acidic (pH 2.5) lower gut for digestion. The combination of rumen protection, high digestibility in the lower gut and high efficiency of energy use explain the superior Net Energy of Lactation value (NEL) associated with Megalac. Rumen protection also means that higher levels of energy can be fed without disrupting the rumen, while also decreasing the risk of acidosis.
No Other Feed Ingredient Provides More Energy for Milk Production than Megalac
Megalac is proven to supply the most energy for milk production. A proportion of energy from every feed is lost in faeces, urine and gas (methane), while inefficiencies in use of energy in feeds leads to further energy losses as heat. The energy remaining after subtraction of these losses from total energy intake is called net energy and is used for maintenance and production purposes. The amount of energy ‘lost’ varies between feeds. Trial work by Drackley (1999) showed that Megalac is highly digestible (96%) and studies at the United States Department of Agriculture (1991) demonstrated that Megalac has the highest measured NEL value (6.52 Mcal/kg DM) of any feed ingredient, meaning that very little energy is ‘lost’.
