<p>The requirement for energy during lactation is determined by the rate of milk production and the composition of the milk. Smaller breeds usually have a higher rate of milk production relative to body weight than larger horses. This is provided for in the program. <br /><br />Milk production in mares, per 100 kg body weight</p>
