Feeding frequency (daily versus three times per week versus once a week) of some supplements may affect animal response. Feeding smaller amounts of protein or energy supplements more frequently decreases the potential for negative impacts on forage intake. However, studies conducted in New Mexico and Texas have shown that hand feeding high-protein supplements once a week results in no significant reduction in performance when compared to feeding supplements three times per week (New Mexico study) or daily (Texas study). Additionally, transportation and labor costs are reduced with less frequent distribution. When feeding a larger amount of a protein supplement (example: 2 lb of 38% protein supplement daily versus 7 lb of a 38% protein supplement delivered twice a week; both equal 14 lb/week), intake variation between cows decreases. Decreased variation likely occurs because more timid cows have a better chance to eat when more feed is delivered at a single feeding. In general, supplements containing 30% protein or more can be feed as infrequently as once a week. In most cases, cattle and waterers are checked at least twice a week, which makes the twice-weekly delivery a logical labor-reducing option compared to daily or alternate-day delivery.
