cassava

(kă-sah′vă) [Sp. cazabe]
A group of perennial herbs of the genus Manihot. The plant is one of the most efficient converters of solar energy to carbohydrate. The root of M. esculenta provides an excellent source of starch and can thrive in poor, dry, acid soils. To be suitable for eating, the root is processed by one of several methods to remove or control the amount of cyanide present. Tapioca is made from cassava.

It was observed statistical difference (p < 0.05) in the process selection of nitrogen intake among the diets with different protein sources and the animals fed the diet containing aerial part of the cassava hay ingested greater (p < 0.05) amount of nitrogen compared to other diets (Table 3).
We observed a higher (p < 0.05) nitrogen content in feces for the diet with aerial part of the cassava hay, principally when compared with soybean meal and cottonseed meal.
Factor A was non-supplementation or supplementation with cassava hay (CH) in the concentrate.
However, supplementing cassava hay for lactating dairy cows tended to increase milk yield, similar to the work of Wanapat (2001) and Kiyothong and Wanapat (2004).
Hence, the hypothesis behind this study was that feeding fresh cassava foliage or cassava hay (10% in total ration) combined with adequate sulfur could provide good sources of protein for milk production in dairy cattle with no toxic effects from cyanide.
Thirty-two, 1st-2nd lactation Holstein-Friesian crossbred dairy cows, ranging from 100-150 days-in-milk (DIM) with 12-15 kg/d milk yield, from the dairy farm of the Faculty of Natural Resources, Rajamangala University of Technology Isan, Sakon Nakhon Campus were used in a randomized complete block design (RCBD) to determine the effects of sulfur on utilization efficiency of fresh cassava foliage and cassava hay. The experiment was arranged in two periods (30 days each) using 16 cows for each period.
Therefore, the objective of this experiment was to investigate the effect of supplementation of sunflower oil and cassava hay based-concentrate with urea-treated rice straw as basal roughage on ruminal fermentation efficiency, and milk productivity in lactating dairy cows.
Cassava hay was used as an ingredient in cassoy-urea pellet with SBM or urea and the pellet was very good source of protein in cattle due to its high rumen bypass protein (Wanapat et al., 2006).
Urea-treated rice straw contained 7.2% CP, while cassava hay (CH) and cassava foliage (FCF) consisted of 24.7 and 25.3% CP, respectively, which were slightly higher than the values reported by Wanapat et al.
Recently, cassava hay (Manihot Esculenta, Crantz) has been growth as a protein foliage supplement in ruminant nutrition especially for dairy cattle and also in beef and buffalo production (Wanapat, 1993; Wanapat et al., 2000a; 2000b; Khang et al., 2005).
Cassava hay is produced from cassava foliage (green stem, petiole and leaves) at a young growth stage of 3-4 months.
