“…Samadi and Yu (2011) reported that autoclaving (120°C; 1 h) reduced α-helix and β-sheet heights of soybean seeds; therefore, the ratio of α-helix to β-sheet in soybean seed was reduced. Samadi et al (2013) observed no difference in α-helix and β-sheet heights in raw, autoclaved, and roasted canola seeds. However, the ratio of α-helix to β-sheet, which correlated with rumen degradation and intestinal digestion characteristics of protein, decreased with autoclaving at 121°C for 60 min and increased with roasting at 120°C for 60 min.…”

“…Theodoridou and Yu (2013b) observed that canola meal had a lower amide I to amide II area ratio than canola presscake, indicating that the area ratio was reduced after desolventizing-toasting during canola processing. However, Samadi et al (2013) indicated that no difference in the area ratio of amide I to amide II was observed when autoclaved (121°C; 1 h) and roasted (120°C; 1 h) canola seeds were compared with unprocessed canola seeds.…”

The objectives of this study were to systematically determine effects of conditioning temperature (70, 80, and 90°C), time (50 and 75 s), and interaction (temperature × time) during the pelleting process on co-products from bio-oil processing (canola meal) in terms of processing-induced changes on (1) protein molecular structure, (2) pellet durability index, (3) detailed chemical profile, (4) metabolic features and fractions of protein and carbohydrate, (5) total digestible nutrients and energy values, and (6) rumen degradable and undegradable content. Pellet durability was increased with increasing conditioning time. Chemical and carbohydrate profiles of co-products were not altered by pelleting process under different conditioning temperatures and times. With regard to protein fraction profiles, pellets conditioned for 50 s had higher soluble crude protein (SCP) and lower neutral detergent insoluble crude protein (NDICP) contents than those conditioned for 75 s (21.7 vs. 20.1% SCP, 16.0 vs. 16.5% NDICP, respectively). Total digestible nutrients and energy values were not altered by processing. Samples conditioned for 50 s had a higher content of rapidly degradable protein fraction (PA2) than those conditioned for 75 s (21.7 vs. 21.1% crude protein). In addition, the slowly degradable true protein fraction (PB2) was affected by the interaction of conditioning temperature and time. However, carbohydrate fractions did not differ with different conditioning temperatures and time. Different temperatures and time of conditioning during pelleting process greatly affect protein profiles without altering carbohydrate profiles. Molecular structure analyses also showed that pelleting altered inherent protein molecular structures of the co-products from bio-oil processing. Future study is needed to detect how molecular structure changes affect nutrient availability in dairy cattle.

“…The feed quality was not determined not only by chemical composition but by other parameters as well such as fiber fraction and digestibility. Samadi and Yu (2011) and Samadi et al (2013) determined energy and protein requirement for ruminant based on Cornell Net Carbohydrate Protein System (CNCPS) in which feed was divided in several carbohydrate and protein fractions. The purpose of this study is to evaluate agro-industrial by products as potential local feed for ruminant animals based on chemical composition, fiber fractions and in vitro rumen fermentation.…”

Animals are considered as source of protein should be improved their productivity with the minimum cost production. Agro-industrial by products have been used as animal feed to reduce feed cost. The purpose of this study is to evaluate agro-industrial by product in Aceh as potential local feed for ruminant animals based on chemical composition, fiber fraction and in vitro rumen fermentation. There were eight sources of agro-industrial by products (sago residues, coconut meal, soybean-ketchup by product, coffee pulp, cacao pod, sago tree, corncob, and rice brand) which were collected from 3 different locations in Aceh. All agro-industrial by product samples were dried at 600C for 24 h and ground to pass a 1 mm sieve. Grounded samples were analyzed to determine chemical composition, fiber fractions and in vitro rumen fermentation. Incubation was conducted at temperature 390C for 48 h in water bath with three replicates. Data for in vitro rumen fermentation were statically calculated by using SPSS differences between treatments were stated (P≤0.05) by using Duncan Multiple Range Test (DMRT). The results indicated that agro industrial by product from coconut meal, ketchup residues, coffee by product, cacao by product, and rice brand can be used as source of protein and industrial by product from sago by product, sago tree and corncob can be used as source of energy. Neutral detergent insoluble CP (NDICP) and Acid detergent insoluble CP (ADICP) were relatively high for sago by product, sago tree and rice brand but relatively low for cacao by product and corncob. The value of incubated pH for most feed samples was in the normal range. In vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD) were significantly difference (P≤0.05) each agro-industrial by products with the highest for sago and the lowest for coffee by product. In conclusion, agro-industrial by products had a potential feed for ruminant animals both as protein and energy sources. However, feed ingredients with high fiber content and low degradability, further treatments such as physical, chemical and biological treatments were required to improve the feed quality.

“…However, most of them are based on wet chemical analysis which are destructive in nature, involve chemical materials, complicated sample preparations, time consuming, and may cause pollutions. Thus, an alternative fast, robust, and effective method is required to analyze feed quality parameters (Samadi & Yu, 2011, Samadi et al, 2013Munawar et al, 2016;Samadi et al, 2018).…”

Feed plays a significant role in livestock production worldwide. Digestibility of feed such as in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD) as well as the fractions of crude fiber such as neutral detergent fiber (NDF) and acid detergent fiber (ADF) can be used as indicators of feed quality. To determine these nutritive parameters, several methods based on solvent extraction and other laboratory analyses are widely employed which are normally time consuming and may cause pollution since this analysis involves chemical materials. Near infrared spectroscopy (NIRS) is one of rapid alternative methods that can be considered to be applied due to its advantages. Therefore, the main objective of this present study is to apply NIRS in determining IVDMD, IVOMD, NDF, and ADF of animal feed samples simultaneously. Reflectance spectra were acquired for animal feed samples in wavelength range from 1000 to 2500 nm. Actual quality and nutritive values were measured by standard laboratory method. Spectra data were corrected by baseline shift correction (BSC), standard normal variate (SNV), and de-trending (DT). Prediction models were developed using principal component regression. Superior results for IVDMD, IVOMD, and NDF predictions were achieved using SNV with correlation coefficient (r) and RPD index of 0.93 and 2.78 for IVDMD, 0.90 and 2.35 for IVOMD, and 0.89 and 2.31 for NDF, respectively. ADF nutritive value was predicted accurately using DT spectrum with r and RPD index of 0.94 and 3.00, respectively. It may be concluded that NIRS can be used and applied as a rapid and simultaneous method in determining nutritive values of feed samples.
