This particular example perfectly highlights why Guinea Pig Fiber Intake And Bowel Health is so captivating.
(1985) diet and three other examples of purified diets that support satisfactory growth (Navai and Lopez, 1973; O'Dell et al., 1989) and reproduction (Apgar and Everett, 1991a,b) are given in Table 4-3. Two of these are agar gel diets—one satisfactory for growth (Navia and Lopez, 1973) and the other for gestation (Apgar and Everett, 1991a,b). Proteins other than casein—such as soybean, egg white (O'Dell et al., 1989), and lactalbumin (Hsieh and Navia, 1980)—have been used, and the lipid source and amount vary, suggesting that the guinea pig does well on a wide range of lipid intakes (Navia and Hunt, 1976). Fiber sources vary from wood pulp to cellophane.
