Liquipron as a Protein Source for Broilers

Eight replicate pens of broiler chicks received each of six dietary treatments from one day of age. Protein levels of 16, 21, and 24% were fed in pelleted diets, with the supplementary dietary protein provided by either soybean meal or yeast protein. Body weights and feed consumption were obtained at 28, 56, and 91 days of age. Increasing protein level gave the only significant growth response at four weeks of age. At eight weeks, increasing protein increased body weight, while the presence of yeast protein significantly depressed body weights. A significant protein effect was noted between the 16 and 21% levels in body weight data of the thirteenth week. Feed required per unit of body weight was significantly affected by protein level at all weighing ages.
