“…These results are similar to those reported elsewhere (Woodward et al 1999) when dairy cows fed with Lotus corniculatus containing condensed tannins, had contributed to a 42 per cent improvement in milk yield and 57 per cent increase in protein percentage without changing feed intake. Source: Granum et al 2002 In recent trials in Vietnam (Nguyen et al 2002) results similar to those already reported (Wanapat et al 1997(Wanapat et al , 2000a. These showed that cassava hay could be produced from an initial harvest of plant tops at four months after planting and with subsequent harvests at one month intervals.…”

“…Planting, cultivation and cutting of cassava for hay making Planting cassava for hay making was done in order to increase the whole crop digestible biomass while roots were considered as a by-product (Wanapat et al 1997(Wanapat et al , 2000a. Early work (Wanapat et al 1997) demonstrated that planting at 60 cm × 40 cm and intercropping between the rows with cowpea or Leucaena could enrich soil fertility and the leaves could be used as food and feed for humans and livestock.…”

Energy and protein sources are of prime importance for ruminants as they stimulate microorganisms in the rumen and enhance the productive functions of the animals. Cassava roots in the form of dry cassava chips or pellets as energy sources and dried cassava leaves and cassava hay as protein sources have been used successfully in ruminant rations. These uses of cassava could provide year-round feed which results in a high yield and good quality of milk and contribute to a more lucrative dairy and beef cattle enterprise, especially for small-holder dairy farming systems. There are many other available feed resources in the tropics of potential use in ruminant feeding and particularly in the development of food-feed-systems that are not only beneficial for human and animals but also for the environment.

The nutritive value of leaves of four varieties of cassava (MS 6, TMS 30555, Idileruwa and TMS 30572) were studied through analysis of their chemical components and degradability of their dry matter (DM) and crude protein (CP) in the rumen of sheep. Results of the chemical analyses showed that the leaves of the four varieties contained different proportions of organic matter which was significantly (P < 0.05) highest in TMS 30572 with value of 935 g/kg DM, while CP (gram per kilogramme DM) was significantly highest in TMS 30555 (240), followed by MS 6 (235), TMS 30572 (208) and least in Idileruwa (177). Mean metabolisable energy (megajoules per kilogramme DM) was significantly (P < 0.05) highest in TMS 30572 (8.2) and similar with Idileruwa (8.0) but different from TMS 30555 and MS 6, respectively (7.8 and 7.6). The mineral contents (gram per kilogramme DM) showed that leaves of MS 6 and Idileruwa had the highest concentrations of K (2.86) and a significantly lowest value (1.83) in TMS 30555. Also, the highest concentration of Ca and Fe (6.81 and 6.23) was recorded in MS 6. The highest Ca:P of 3.20 was obtained in TMS 30555. DM degradation characteristics and effective degradability varied significantly (P < 0.05) and were consistently highest in TMS 30572. The washing loss (a) ranged from 15.9% in MS 6 to 21.3% in TMS 30572. TMS 30572 tended to have higher (P = 0.546) insoluble but fermentable fraction (b) than all other varieties. Moreover, the potential degradability (a + b) tended to be higher (P = 0.041) in TMS 30572 (69.5%) followed by TMS 30555 (67.1%) and the lowest was in Idileruwa (42.7%). The highest effective degradability was recorded in TMS 30572 (63.9%) and the lowest in Idileruwa (40.7%). The degradation rate constants (c) of Idileruwa was significantly higher (P = 0.001) than those of MS6, TMS 30555 and TMS 30572. The results generally indicated that the leaves could be ranked for their potential feeding value as TMS 30572 (71.5%) > MS6 (65.8%) > Idileruwa (63.0%) > TMS 30555 (50.4%). It is therefore concluded from this study that leaves of TMS 30572 and MS 6 have good potential as feed resources for ruminant animals and could be used in ruminant feeding as protein source ingredient.

“…The HCN content is normally between 200 and 800 mg/kg DM in fresh cassava leaves (Ravindran, 1991). Sundrying the leaves to produce cassava hay will result in a reduction in HCN (Ravindran, 1992 andWanapat et al, 2000). The concentration of HCN in the diets, between 0 and 32.4 mg/kg DM was below the recommended 50 mg/kg DM safe level of HCN in the diet (Bolhuis, 1954).…”
