Feed restriction should be heaviest during this phase of growth. Take caution, but do not become alarmed if body weights are slightly below the average shown in the weight guide. This method will allow you to begin increasing body weight and feed allocation just prior to the onset of production. Protein intake during this phase should range from 9.5 to 11 grams on a daily basis. Higher levels of protein intake tend to cause lower production peaks.
