The effect of heat treatment and germination on the proximate and mineral composition, HCH, tannins, phytic acid and the in vitro protein digestibility of Mucuna utilis seeds were studied. The raw seeds had a protein content of 35.4%, 7.7% crude fibre, 3.2% ether extract, 5.8% ash and 47.9% carbohydrates on a dry matter basis. The germinated and dehulled seeds had 40.5% crude protein 2.2% crude fibre, 3.4% ether extract, 7.0% ash 47.0% carbohydrates, while the heat -treated seeds had 34.4% crude protein, 11.9% crude fibre, 3.3% ether extract, 9.4% ash and 41.1% carbohydrates. Potassium and iron were the most abundant minerals while the least were sodium and copper. Germination caused a reduction in the levels of all minerals while heat treatment also caused a reduction in the levels of the minerals but with exception of Ca, Mg and Zn. Processing caused a reduction in all the levels of anti-nutritional factors assayed. The in-vitro protein digestibility of the raw seeds was 89.4%; 91.7% for the heat-treated seeds and 76.0% for the germinated seeds.

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.

Background: Soybean milk by-product (SMBP) is a potential alternative feed ingredient in swine diets due to its high protein content. However, information on energy and nutritional values of SMBP used as swine feed ingredient is limited. Objective: To estimate energy values and protein digestibility of SMBP in pigs based on in vitro assays. Methods: Four SMBP samples were obtained from 3 soybean milk-producing facilities. In vitro total tract disappearance (IVTTD) and in vitro ileal disappearance (IVID) of dry matter (DM) in the SMBP samples were determined. In vitro ileal disappearance of crude protein was determined by analyzing crude protein content in undigested residues after determining IVID of DM. Digestible and metabolizable energy of SMBP were estimated using gross energy, IVTTD of DM, and prediction equations. Results: Sample 4 had greater IVTTD of DM than that of sample 3 (97.7 vs. 94.4%, p<0.05), whereas IVID of DM in sample 4 was lower compared with sample 1 (53.5 vs. 65.0%, p<0.05). In vitro ileal disappearance of crude protein in sample 2 was greater than that in sample 1 and 3 (92.6 vs. 90.6 and 90.1%; p<0.05). The estimated metabolizable energy of SMBP ranged from 4,311 to 4,619 kcal/kg as-is basis and the value of sample 3 was the least (p<0.05) among SMBP samples. Conclusion: Energy values and protein digestibility should be determined before using SMBP in swine diets.

A biotechnological approach including enzymatic treatment (protease and xylanase) and lactic acid bacteria fermentation has been evaluated to enhance the nutritional value of semolina pasta enriched with hemp, chickpea and milling by-products. The intense (up to circa, (ca.) 70%) decrease in the peptide profile area and (up to two-fold) increase in total free amino acids, compared to the untreated raw materials, highlighted the potential of lactic acid bacteria to positively affect their in vitro protein digestibility. Fermented and unfermented ingredients have been characterized and used to fortify pasta made under pilot-plant scale. Due to the high contents of protein (ca. 13%) and fiber (ca. 6%) and according to the Regulation of the European Community (EC) No. 1924/2006 fortified pasta can be labelled as a “source of fiber” and a “source of protein”. The use of non-wheat flours increased the content of anti-nutritional factors as compared to the control pasta. Nevertheless, fermentation with lactic acid bacteria led to significant decreases in condensed tannins (ca. 50%), phytic acid and raffinose (ca. ten-fold) contents as compared to the unfermented pasta. Moreover, total free amino acids and in vitro protein digestibility values were 60% and 70%, respectively, higher than pasta made only with semolina. Sensory analysis highlighted a strong effect of the fortification on the sensory profile of pasta.

In this paper, a mathematical model was used to evaluate a dynamical hybrid system for optimizing and controlling the efficacy of plant-based protein in aquafeeds. Fishmeal (FM), raw rapeseed meal (RM), and a fermented meal with yeast (RM-Yeast) and fungi (Aspergillus oryzae RM-Koji) were used as test ingredients for the determination of apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, energy, and essential amino acids (EAA) for olive flounder (Paralichthys olivaceus, 7 ± 0.02 g) using diets containing 0.5% Cr2O3 as an inert indicator. Among all ingredients tested, FM had the maximum ADC of dry matter ( P < 0.05 ), protein ( P < 0.05 ), lipid ( P > 0.05 ), and energy ( P > 0.05 ). Fermented meals (RM-Yeast and RM-Koji) showed higher ADC ( P < 0.05 ) of crude protein compared with RM, while there was no significance in ADCs of crude lipid and energy among different forms of rapeseed meal. Besides, ADC of crude lipid for RM-Yeast and RM-Koji, on the one hand, and ADC of gross energy for RM-Yeast, on the other hand, were not varied from that for FM ( P > 0.05 ). Amino acid digestibility reflects protein digestibility in most cases. Interestingly, protease, lipase, and amylase activities were better expressed in RM-Koji, RM-Yeast, and FM over RM, respectively. The current results deliver important information on nutrients and energy bioavailability in raw and fermented RM, which can be implemented to accurately formulate applied feeds for olive flounder. Compared with other applicable systems, the complexity of the approach implemented has been considerably reduced.

Fifteen oilseed cakes from sunflower, pomegranate, cardoon, tobacco and hemp were characterized with regard to chemical composition, Cornell Net Carbohydrate and Protein System (CNCPS) fractionation, in vitro digestibility of dry matter, neutral detergent fiber, and crude protein. All the cakes presented low moisture, rather variable ether extract contents and medium to high levels of crude protein and neutral detergent fiber. The cakes significantly differed in terms of CNCPS partitioning and in vitro digestibility. Tobacco and hemp cakes presented high contents of slow degradable fractions of crude protein and carbohydrate joined to good post-ruminal protein digestibility. Cardoon cakes presented the highest rumen protein degradability. Based on crude protein content and intestinal digestibility of rumen undegraded protein, cakes of tobacco and hemp showed the better potential as alternative protein supplements for ruminants, while pomegranate appears to be the least suitable for ruminant feeding.

The article states that industrial fish farming in inland waters has become increasingly important in the recent years and it is one of the sources for satisfying the needs of people in the high-protein foods. The fish meat is an extremely rich source of proteins, which are easily digested, vitamins, polyunsaturated fatty acids, macro- and microelements. One of the priorities of the development of the fish farming in Ukraine is the cultivation of the Clarias gariepinus. Clarias gariepinus or African sharptooth catfish is a species of catfish of the family Clariidae, the airbreathing catfishes. In 2017, with the support of the Ukrainian State Agency, the Institute of Fisheries of Ukraine on the part of the state and the companies Vismar Aqua, Aquaprom and the Dutch company Trouw Nutrition («Skretting»), the program was developed to increase the cultivation of the Clarias gariepinus under the name Clarias gariepinus - 2020. The objective of the program is to provide 2020 tons of Clarias gariepinus until 2020. Today, the production of the Clarias gariepinus in Ukraine is about 500 tons per year; about50 farms are engaged in cultivation. That is why the production of balanced domestic compound feeds for Clarias gariepinus is an important task of the feed industry of Ukraine. The theoretical study was devoted to the problem of the production of compound feeds for the Clarias gariepinus. The nutritional value of compound feeds for Clarias gariepinus a depends on the stage of the life cycle of this species of fish. The above world leaders are manufacturers of compound feeds for Clarias gariepinus, the analysis of granule size and nutritional value of compound feeds on the content of crude protein in prestarting, starting, growth and finishing periods respectively. The requirements for the content of essential and non-essential amino acids, minerals (micro and micronutrients), waterand fat soluble vitamins and restrictions on the content of crude fiber are given. Indicated the main and additional raw materials, traditionally used in the manufacture of data feed advanced companies. The main components are fish meal, produced under relatively low drying conditions, wing meal, corn and wheat gluten, soy products, by-products of extraction oil and press production oil (soya, sunflower and other cakes and meals), premisex, carotenoids like astaxanthin. The feeding programs of the Clarias gariepinus of various manufacturers have been analyzed and their own feeding program has been developed for this species of fish; it divides the period of cultivation of the Clarias gariepinus into prelaunch, starting, growth and finishing ones. For prestart mixed feeds, the content of crude protein should be at least 45%, raw fat at least 12%, raw fiber not more than 1.8%, gross energy not less than 13.7 MJ, raw ash not more than 8%. For starter feed, the content of crude protein should be at least 42%, raw fat at least 12%, raw fiber not more than 3%, gross energy not less than 13.1 MJ,raw ash not more than 9.5%. For grower’s feeds, the content of crude protein should be at least 38%, raw fat at least 12%, crude fiber not more than 3%, gross energy not less than 12 MJ, raw ash not more than 9.5%.
