[Evaluation of nutritional potential of fish in diets based on beans (Phaseolus vulgaris) and a cereal/corn (Zea mays) and/or rice (Oryza sativa)].
p6e complementation between corn and fish, and rice and fish was evaluated for the purpose of establishing the required levels of each constituent in the mixture to obtain the optimum value in the biological evaluations for each diet. The optimum fish levels were around 10 and 6% for the corn and rice diets, respectively. Complementary levels of fish in the bean: corn and bean:rice diets were evaluated in the same manner. The best values in the biological evaluation were obtained with only 2% of fish. The economical analysis of these mixtures revealed that the nutritional value of the Central American rural diets can be increased with the introduction of fish in small quantities in the habitual diets, without increasing the family food expenses.
[Growth of the water hyacinth (Eichhornia crassipes (Mart) Solms Laubach) in the tropics].
The growth and reproduction rates of water hyacinth (Eicchornia crassipes (Mart) Solms Laubach) in tropical areas, under natural and fertilized controlled conditions, were studied. The fertilizer used was swine fecal matter at three different levels: 1.25, 2.5 and 5%. The highest rate of growth was found with the 2.5% concentration, and this value was 49.16 g/m2/day on a dry-weight basis. Under natural conditions the rate of growth was 18.39 g/m2/day on a dry-weight basis. These results represent a yearly production in ton/ha among the highest reported in the world.
