| Popis: | AS A RESULT of the low vitamin A intake during extended dry seasons, vitamin A deficiency is a severe nutritional problem of animals in the American tropics. It is now apparent that not only inadequate dietary intakes but also high environmental temperatures (Squibb, Guzman and Scrimshaw, 1954) and, in poultry at least, diseases such as coryza and cholera (Squibb et al., 1955) are additional factors responsible for low serum vitamin A levels in animals. All of these are common stress factors in the tropics. Squibb, Guzman and Scrimshaw (1953, a, b, c) and Squibb, Mendez, Guzman and Scrimshaw (1954) have demonstrated that vitamin A deficiencies may be overcome by feeding dehydrated forage meals prepared from kikuyu grass (Pennisetum clandestinum), ramie (Boehmeria nivea), Desmodium sp., especially the species D. intortum, or banana leaves. In this report the utilization of the carotenoids of four additional forages was evaluated in New Hampshire chicks. . . . |
