“…Ash content was similar (MPOC), close (2POC) and higher (3POC) than values reported in the literature (Vlyssides et al ., 2004; Borja et al ., 2006; Weinberg et al ., 2008; Dermeche et al ., 2013). For CP, values in the literature were lower (MPOC and 3POC) and similar (2POC) to the current results (Al-Masri, 2003; Molina Alcaide et al ., 2003; Vlyssides et al ., 2004; Mioč et al ., 2007; Dermeche et al ., 2013; Neifar et al ., 2013). The CP increase by period might be explained by late varieties' composition, growing conditions, origin and maturity levels of olives used in these periods, which is often black and completely mature, that could affect OC composition (Leouifoudi et al ., 2015).…”

“…(2001) found an increase of CP in olive fruit of Arbequina cultivar by a maturity stage (from 1.3 to 1.6% DM), correlated positively with oil content and explained by oleosin proteins that participate in the storage of lipids in oilseeds. The EE by the extraction process was higher than values in the literature (Borja et al ., 2006; Mioč et al ., 2007; Sadeghi et al ., 2009; Dermeche et al ., 2013; Neifar et al ., 2013), probably due to the methods and programmes used by extraction mills and also by extraction process management. The high contents of NFE, which represents the highly digestible carbohydrates, in 2POC and 3POC might be related to the soluble sugars in wastewater that is higher in these OCs than in MPOC.…”

Chemical composition and in vitro digestibility of alternative feed resources for ruminants in Mediterranean climates: olive cake and cactus cladodes

et al. 2019

Olive cake (OC) and cactus cladodes (CCs) are two alternative feed resources widely available in Mediterranean areas. Their use in ruminant diets was assessed according to their chemical composition, secondary compound levels and digestibility. The effects of the olive oil extraction period and process, and CCs age and sampling period were evaluated. OC was collected monthly, from November to January, from mills using either a mechanical press or 2-phase or 3-phase centrifugation processes. CCs were collected fortnightly according to age (young and mature) from April to June. Two-phase OC had the lowest content of dry matter (DM), the highest nitrogen-free extract (NFE) and total and hydrolysable tannins and was more rapidly fermentable. Mechanical press OC was the least digestible. OC DM, protein and NFE were affected linearly by the extraction period. Gas production (GP), in vitro digestibility parameters and dry and organic enzymatic digestibility changed with the extraction period. Therefore, OC chemical composition and in vitro digestibility depended mainly on the extraction process and period. Compared to mature CCs , young CCs contained more water, protein, ether-extract and phenolic compounds, but less ash and fibre. GP and digestibility parameters were not affected by age, but in vitro organic matter digestibility and microbial biomass production were higher in young cladodes. CCs chemical composition, GP and digestibility parameters were influenced by the collection period. Due to its limited nutritional quality, OC should be enriched in nitrogen, while CCs could be considered as highly valuable forage in ruminant diet.

“…Lignin is known to reduce the digestibility of plant cell wall (Shrivastava et al, 2014). Despite the existence of physical (i.e., grinding) and chemical (i.e., soaking with sodium hydroxide or alkaline hydrogen peroxide solutions (Ghasemi et al, 2013)) methods to improve the nutritive value of fibrous by-products, research is currently focused on biological approaches, more environmentally friendly and widely acceptable (Basu et al, 2002;Kuhar et al, 2008;Neifar et al, 2013).…”

“…Cellulose resources are abundant in nature, especially in China, but their low protein content and low digestibility prevent their use as feed for non-ruminant animals in feedlots [ 2 ]. Bioconversion of these resources by solid state fermentation (SSF) has been widely used due to its low cost, easy operation, and variety of uses [ 3 – 6 ]. The microorganisms produce cellulase, degrade components of the cell wall and synthesize microbial protein by SSF.…”

In order to assure the consistency of the final product quality, a fast and effective process monitoring is a growing need in solid state fermentation (SSF) industry. This work investigated the potential of non-invasive techniques combined with the chemometrics method, to monitor time-related changes that occur during SSF process of feed protein. Four fermentation trials conducted were monitored by an electronic nose device and a near infrared spectroscopy (NIRS) spectrometer. Firstly, principal component analysis (PCA) and independent component analysis (ICA) were respectively applied to the feature extraction and information fusion. Then, the BP_AdaBoost algorithm was used to develop the fused model for monitoring of the critical time in SSF process of feed protein. Experimental results showed that the identified results of the fusion model are much better than those of the single technique model both in the training and validation sets, and the complexity of the fusion model was also less than that of the single technique model. The overall results demonstrate that it has a high potential in online monitoring of the critical moment in SSF process by use of integrating electronic nose and NIRS techniques, and data fusion from multi-technique could significantly improve the monitoring performance of SSF process.
