Winter protein requirements of bobwhite quail

Three experiments involving 714 bobwhite quail were conducted at the Patuxent Research Refuge, Bowie, Maryland, during the winters of 1939-1941 to determine the protein requirement of quail maintained throug'h the winter.....Considering survival, live weights, feed consumption, and subsequent reproduction by the birds, the-9 to 13 per cent levels of crude dietary protein gave as good results as higher levels eggs, which in all cases was over 90 per and in some respects were better.....On the basis of these studies, it is recommended that the winter maintenance diet for bobwhite quail contain . about 11 to 12 per cent of crude protein. The following diet (parts by weight) conforms to these specifications and should be satisfactory:...Ground yellow corn 85.6....Dehvdrated alfalfa leaf meal 5 .O.....Soybean oil meal 7.0.....Special steamed bonemeal 1.2....Salt (or Salt Mixture II,see text) 1.0...Vitamin A and D feeding oil, fortified 0.2.
