Since 1990 we have undertaken a large number of experiments and conducted research on the development and use of cassava roots and leaves as animal feed resources, in order to explore the possibility of substituting cassava-based feeds for those of grain, thus saving grain for human consumption that was previously used for feeding animals. We have conducted chemical analyses to determine the nu...

Vitamin A deficiency (VAD) is the world’s commonest cause of childhood blindness. More than half of these cases occur in developing countries. Animal sourced foods though good sources of vitamin A are too expensive for poor rural people. Crops biofortified with provitamin A offer a convenient and accessible source of vitamin A. The other micronutrient programs of fortification and supplementati...

The purpose of the study was to determine competitive and comparative advantages sustainability cassava farming in East Lampung Regency. population farmers is 1,100 using Slovin formula, so a sample 92 obtained. Sampling done by purposive sampling technique. Data analysis used PAM (Policy Analysis Matrix) analysis. results were PCR coefficient value 0.3397 DRCR 0.1216. < 1 indicates that Reg...

The effect of cassava root ensiled with cassava top or legumes on voluntary feed intake and milk production were determined in 12 dairy cows using a 4×3 change-over design. Experimental period were 30 days long and consisted of 14 days of adaptation. Silage was prepared from cassava root mixed with cassava top or legumes at ratio 60:40. Cows were allotted at random to receive ad libitum one of ...

Cassava is grown on the floodplains of Solimões river and guarantees food security income for farmers. However, negative interference weeds can result in a significant yield loss crop. Therefore, aim this study was to evaluate selectivity herbicides efficiency chemical weed control cassava ‘Aipim-manteiga’ cultivar, floodplain river, Iranduba, Amazonas. The experimental design randomized blocks...

Local feed resources, particularly low-quality roughages and agricultural crop-residues, are of prime importance for ruminants raised in the tropics. These feeds exhibit close relationships with rumen ecology, microbes and rumen fermentation patterns. A number of dietary factors could influence rumen fermentation especially the basal roughage source, its physical form and fermentation end-produ...

Cassava (Manihot esculenta Crantz) is an important staple crop in Nigeria. It provides approximately 80 % of the caloric intake High starch content and fresh root yields are for commercialization cassava. a perennial crop, it can be produced all year round. However, cassava yield strongly influenced by environmental conditions such as rainfall. Therefore, to identify planting harvest periods at...

Bemisia tabaci (Gennadius) is one of the most important pests of cassava in Africa and several countries of Asia due to the damage caused by direct feeding, the excretion of honeydew, and its capacity as a vector of cassava mosaic geminivirus. There is a general consensus that B. tabaci is a complex of morphologically indistinguishable populations with different biotypes. In the Americas, the p...

Cassava (Manihot esculenta Crantz), a shrubby tree of the Euphorbiaceous family, is an extensively cultivated plant in many tropical countries. Annual production estimate in Nigeria was 34 million tonnes in 2009 FAO [1]. Cassava root is a major source of dietary carbohydrate for human and livestock. It is widely accepted that plants grown in various location produced different quality and quant...
