Item The Feeding Value of Cassava Meal For Broiler Chicken(1988) Ochetim, S.; Chimwao, A.M.P; University of the South Pacific, Alafua Campus, Western SamoaUp to 50% level of maize substitution with cassava did not affect (P>0.05) final body weights, feed efficiently and carcass yield of chickens. Levels of substitution higher than 50% reduced (P:E;0.05) growth rate and feed efficiency. Feed consumption, dressing percentage and liver weights were not affected (P>0.05) by level of maize substitution with cassava in the diet. Feed costs were correspondingly reduced with increasing level of cassava in the diet. Gross profit margins increased with increasing level of cassava in the diet up to 50% level of substitution. At the 75 and 100% replacements of maize with cassava, gross profit margins were still higher than those obtained at the 25%, levels of cassava substitution. It is concluded that nutritionally, cassava can be used to replace up to 50% of maize in broiler diet without impairing performance. However, higher levels, 75 and 100% replacements still produce high economic returns.Item Napier Grass Ensiled With Broiler Poultry Waste as a Feed for Dairy Cows(1989) Odhuba, E.K.; Kenya Agricultural Research Institute (KARI)Napier Brass (Pennisetum purpureum) remams the most Imponant fodder crop for small and medium scale dairy farmers in Kenya to-day (Karanja, 1981; Potter and Anindo, 1984 and Maiisu. 1985). Anindo and Potter (1986) reported a milk production level of 10.5 kg per day from dairy cowsted on Napier grass alone. The production increased to 15 kg per day following supplementation with concentrate. These yield levels are quite encouraging considering that they are at least twice the level reported by Stotz (1983) as the national average for Kenya. However, it would be difficult to achieve sustainable high milk yields because of seasonality on grass production and high costs of concentrates. Besides, the nutritive value of napier grass tends to decline rather deeply at advanced stages of maturity (french. 1941 and Mashau and Bredon. 1%3). Consequently, conservation of the grass as silage would offer a sound basis for a year-round feeding programme.
