The use of cassava leaf silage as a substitute for concentrate feed in sheep

Abstract

We aimed to evaluate nutrient intake, performance and rumen fermentation of sheep fed cassava leaf silage (CLS). Sixteen growing Java thin-tailed male sheep (body weight (BW) 20.4 ± 1.9 kg) were fed one of the following dietary treatments: T0 (100 % forage); T1 (100 % chopped forage); T2 (80 % chopped forage + 20 % concentrate); and T3 (80 % chopped forage + 20 % CLS). Nutrient intake, production performance and rumen fermentation characteristics were measured. There was no significant effect on the consumption of dry matter, whereas there was a significant effect (P < 0.05) on the consumption of crude protein, fat, crude fibre and total digestible nutrients. Concentrate or CLS at a 20 % level could increase BW and feed efficiency. No significant difference was observed in total bacteria; however, concentrate could increase total protozoa (P < 0.05). Total volatile fatty acids were higher in T2 than in T3, but ammonia concentration was higher in T3 than in T2. In conclusion, feeding 20 % cassava leaf silage greatly improved sheep performance, approaching that achieved by feeding concentrate.

Pruning as a strategy to improve the nutritional value of the aerial parts of industry- purpose cassava clones

“…As avaliações foram realizadas aos dezoito meses após o plantio, sendo os dados submetidos à análise de variância e as médias comparadas pelo teste de Tukey. O clone 330/09 se destacou por apresentar maior INTRODUCTION Cassava is cultivated mainly for to its starchy roots, which is used in human food (RINALDI et al, 2015;RINALDI et al, 2019), animal feed (OLIVEIRA et al, 2014;GONÇALVES et al, 2015;SUDARMAN et al, 2016;, and as a raw material for various industrialized products (ZHU, 2015). This plant species displays drought tolerance and the ability to grow in acidic soils with low fertility, as well as flexibility in terms of planting and harvesting times, and in adapting very well to the climate and soil conditions of Brazil .…”

Condensed tannin-amended cassava silage: fermentation characteristics, degradation kinetics andin-vitrogas production with rumen liquor

“…The silage material was composed of the upper third section of leaves + fine stems of cassava ( Manihot esculenta Crantz), because the thicker stems are less acceptable to animals, and producers use the thicker stems for cassava replanting (Sudarman et al 2016; Polthanee & Wongpichet 2017). Plants were approximately 6 months old and 2·00 m tall, when this material naturally had approximately 300 g DM/kg.…”

Protein Fractionation and Utilization of Soybean and Redbean as Affected by Different Drying Temperature

“…Protein supplements are often used for feeding ruminant livestock since the requirements generally cannot be met by only consuming forage sources such as grasses and agricultural residues for optimum animal production. Some protein supplements that have been used to enhance feed protein content of ruminant livestock in Indonesia are: concentrate mixture (Astuti et al, 2009;Wulandari et al, 2014), and some feed stuff, such as: katu (Sauropus androgynous) leaves (Marwah et al, 2010), moringa leaves (Jayanegara et al, 2010), cassava leaves (Sudarman et al, 2016), rice bran (Endrawati et al, 2010), and mungbean fodder (Zahera et al, 2015). Some beans can also been used as protein supplements from plant origins.…”
