“…Retnaningrum et al [12] reported that the VFA increased with the addition of cassava meal in the ration, but at the 70% proportion of cassava meal, drastically decreased total VFA, acetate, propionate, and butyrate due to inadequate proportion of protein source. Santos et al [13] reported that cassava peel tended to decrease propionate and increase the acetate concentration in replacement of corn. Apart from VFA levels, CH4 can be assessed for feed efficiency parameters.…”

“…Retnaningrum et al [12] reported that the use of cassava meal as an energy source to supplement maize stover basal diet had the highest digestibility and daily weight gain of crossbred Limousine. [13] mentioned that cassava peel can replace corn as an energy source in ration rated from ruminal parameters on small ruminants. Mulyati et al [14] stated that cassava and moringa leaves potentially as a supplement on low-quality roughages to support rumen microbial growth and activity due to high protein content.…”

This study was conducted to evaluate the effects of different levels of protein sources in a concentrate cassava peel diet on volatile fatty acid (VFA) concentration and efficiency of microbial protein synthesis (EMPS) by in vitro method. The five diet treatments in this study consisted of cassava meal (CM), cassava peel (CP), cassava leaves (CL) and moringa leaves (ML) with the proportion applied were T1=CM70% + CP20% + CL5% + ML5%; T2=CM60% + CP20% + CL10% + ML10%; T3=CM50% + CP20% + CL15% + ML15%; T4=CM40% + CP20% + CL20% + ML20%; T5=CM30% + CP20% + CL25% + ML25%. The experiment used a randomized block design with five treatments and three replications. The results showed that increasing the level of protein sources in the ration tended to increase the value of total VFA, acetate, propionate, CO2, and CH4 in which T3 had the highest values. However, the effect of treatments were significant in EMPS value (P<0.01). It was concluded that increasing levels of cassava and moringa leaves in the concentrate cassava peel diet tended to increase the value of total VFA, acetate, propionate, butyrate, CO2, and CH4 which led to a significant increase in EMPS values.

“…Inherently, the resultant quality of the produced AC from a lignocellulosic precursor depends on the reactions and interactions of the different components of the precursor, mainly cellulose, hemicellulose, and lignin (Gani & Naruse, 2007) Cassava peel is one of the prospective precursors for AC production. Leveraging the properties of cassava peels for AC is of economic importance given the few competitive applications like animal feed (Adekunle, Orsat, & Raghavan, 2016;Santos et al, 2015) and, potential energy production (Okudoh, Trois, Workneh, & Schmidt, 2014). Like other lignocellulosic biomass, for cassava peel to be harnessed for AC production, it requires pre-treatment to counteract its recalcitrance nature towards thermochemical processing.…”

The search for alternatives to fossil based commercial activated carbon (AC) continues to reveal new eco-friendly potential precursors, among which is agricultural waste. The key research aspect in all these endeavors is empirical ascertainment of the core properties of the resultant AC to suit a particular purpose. These properties include; yield, surface area, pore volume and the active surface groups. It is therefore pertinent to have process conditions controlled and tailored towards these properties for the required resultant AC. Highly porous AC was prepared from cassava peels by pre-treating and activating them using NaOH and KOH respectively. The carbonization temperatures were between 480 and 780°C in an activation-carbonization stepwise process using KOH as the activator at a KOH: peel ratio of 5:2 (mass basis). A 42% maximum yield of AC was realized along with a total pore volume of 0.756 cm3g− 1 and BET surface area of 1684 m2g− 1. The AC was dominantly microporous for carbonization temperatures below 780°C but a remarkable increase in mesopore volume (0.471 cm3g− 1) relative to the micropore volume (0.281 cm3g− 1) was observed at 780°C. The Fourier transform infra red (FTIR) spectroscopy for the pre-treated cassava peels showed distortion in the C-H bonding depicting possible elaboration of more lignin from cellulose disruption by NaOH. A carboxylate stretch was also observed owing to the reaction of Na+ ions with the carboxyl group in the raw peels. FTIR showed possible absorption bands for the AC between 1425 and 1712 cm− 1 wave numbers. Besides the botanical qualities of the cassava peel genotype used, pre-leaching the peels and also increasing holding activation temperature above the melting point of potassium enabled the modified process of producing highly porous AC from cassava peel. The SEM imaging showed well-developed hexagonal pores in the resultant AC.

“…Therefore, the use of alternative tropical ingredients as substitutes for corn and soybean meal in formulations of confined sheep diets is recurrent. Santos et al (2015), for example, observed that corn can be completely replaced by cassava peel associated with urea in sheep diet. On the other hand, despite being forage rich in moisture, Pinto et al (2011) recommended the replacement of 75% of corn ground with spineless cactus in confined lambs diet.…”

In semi-arid zones, feedlots are considered a tool to minimize the impacts of seasonal forage on the production of sheep meat in the tropics. However, the use of alternative tropical ingredients as substitutes for corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) meal in formulations of confined sheep diets is recurrent. The aim of this study was to evaluate the effect of diets containing corn and soybean meal (CS), corn (CU), cassava (Manihot esculenta Crantz) root (CRU) or spineless cactus (Opuntia ficus-indica [L.] Mill., SCU) associated with urea on the performance, carcass characteristics and meat quality of confined lambs. Forty non-castrated Santa Inês sheep with average age of 150 d and average initial weight of 22.6 ± 2.3 kg were confined in individual pens for 76 d and slaughtered. The diets effects were contrasted by Tukey test. Empty body weight was different among the treatments (P < 0.05) and was 27.3, 25.3, 23.0 and 21.1 kg for the animals fed CS, CU, CRU and SCU, respectively. CS diet presented higher cold carcass weights while SCU diet presented lower cold carcass weights (P < 0.05) (11.37 kg) and higher cooling losses. Luminosity, yellow color intensity and meat moisture content were higher (P < 0.05) in SCU than CS. Liver, skin and internal fat weights were similar (P > 0.05) in CU and CRU, but higher (P < 0.05) than SCU. The replacement of corn and soybean meal for different carbohydrate sources associated with urea reduces the body weight components in confined sheep.
