Effect of Protamine Zinc Insulin on Feed Intake and Weight Gain in Broiler Chicks

Ten-day old Robro broiler chicks were used to test the effect of daily subcutaneous injections of two insulin levels (5- and 10-IU.kg -1 BW) administered for two different periods (5 and 21 days). Birds which received either 5- or 19-IU insulin significantly increased their feed intake over those of...

Zusammenfassung:Ten-day old Robro broiler chicks were used to test the effect of daily subcutaneous injections of two insulin levels (5- and 10-IU.kg -1 BW) administered for two different periods (5 and 21 days). Birds which received either 5- or 19-IU insulin significantly increased their feed intake over those of the controls ( P < 0·05). However, the lower insulin dose was found to be more effective in increasing both the feed consumption and weight gain of the birds, especially if administered for a long period. Between the injection periods, the high insulin dose seemed to have a greater carry-over effect. On the other hand, the administration of 5- or 10-IU insulin for either 5 or 21 days had no effect on efficiency.
