A Type of Nutritional Leg Paralysis Affecting Chicks

The Relative Vitamin G Content of Dried Whey and Dried Skimmilk

“…Hauge and Carrick (1926) were the first to present evidence showing that a growthpromoting factor, now known as vitamin G, is required by poultry in addition to vitamin B. Later Norris and co-workers (1930Norris and co-workers ( , 1931Norris and co-workers ( , 1933 and Bethke et al (1931) confirmed these results and called attention to the great requirement of poultry for this vitamin. On account of this the vitamin G content of milk by-products and other sources of this vitamin becomes an important practical consideration.…”

“…The problem was complicated at first by the probability that vitamin G is a complex consisting of two or more phases as pointed out by Ringrose and co-workers (1931) and later by Bethke et al (1931). Although it has not been established that the first two phases are separate, the factors of the complex may be designated as follows: (1) A growth-promoting (hatchability-promoting) phase; (2) An anti-paralytic phase; (3) An anti-pellagric phase.…”

The Utilization of Wheat and Wheat By-Products in Feeding Young Chickens

“…This unusual paralysis was not observed where the chicks received large amounts of wheat, either 15 percent of bran, or bran and middlings. Moreover, the paralysis did not involve the toes, nor did it in any way resemble the nutritional paralysis described by Bethke, et al (1931). Ground wheat is not an appreciable source of the factor which prevents nutritional paralysis whereas wheat, and bran and middlings were effective in preventing this peculiar paralysis.…”

Mineral Content of Tibiae from Chicks with Slipped Tendon

“…It is the opinion of Bethke, Record, and Kennard (1931) ;Norris, Heuser, Wilgus, and Ringrose (1931); Payne, Hughes, and Leinhardt (1932);and Hunter, Dutcher, and Knandel (1931) that the occurrence of slipped tendon in growing chicks is definitely increased by an excess of calcium and phosphorus in the ration. On the other hand Titus (1932) believes that other factors of the ration being favorable "a mere excess of mineral ingredients does not cause a higher percentage" of slipped tendons.…”
