This study evaluated the chemical composition and ruminal degradability of dry matter (DM), neutral detergent fiber corrected for ash and protein (NDFap) and crude protein (CP) in byproducts of African oil palm (palm cake, kernel or fiber), macaúba (pulp cake and kernel cake), acai (acai fruit), babassu (kernel cake) and pineapple (peel, crown and bagasse silage). Nineteen rumen-fistulated sheep were kept in individual stalls, receiving a daily diet composed of elephant grass silage and corn and soybean concentrate. After preparation in nylon bags, the byproduct samples were incubated for 0, 3, 6, 12, 16, 18, 24, 48, 72, 96, 120 and 144 hours, with three replicates of each ingredient per incubation time. The divergence between the protein nutritional value and energy nutritional value, based on discriminatory variables between groups, was estimated by cluster analysis. The effective degradability of DM, NDFap and CP for the different byproducts was, respectively, 35.9, 26.9 and 59.0% for palm cake; 48.3, 34.3 and 76.4% for palm kernel; 21.1, 6.6 and 50.3% for palm fiber; 34.3, 15.0 and 52.8% for macaúba pulp cake; 58.1; 63.0 and 51.6% for macaúba kernel cake; 49.7, 49.6 and 41.8% for babassu cake; 53.4, 40.5 and 79.8% for pineapple bagasse silage; and 21.3, 17.0 and 38.9% for acai fruit. Based on their NDFap and CP characteristics, the feeds were clustered in up to four different groups.

The aim of this study was to evaluate nutritional value, fermentation losses, and aerobic stability of elephant grass silage (Pennisetum purpureum Schum.) treated with exogenous fibrolytic enzymes. The experiment was conducted in a completely randomized design with four replicates (experimental silos) and five levels of fibrolytic enzymes (0, 1.5, 3.0, 4.5 and 6.0%). For this, the elephant grass was ensiled at 70 days of age in plastic buckets with 20L capacity. Silos were opened 60 days after sealing. Analyses were made for chemical composition, in vitro dry matter digestibility (IVDMD), effluent losses (EL), gas losses (GL) and dry matter recovery (DMR), as well as the aerobic stability of the silage. Data were analyzed with PROC REG of SAS® University, at 5% probability. There was an increase in IVDMD content (p < 0.0001) and reduction in NDF and ADF contents (p < 0.0001) according to enzyme levels. These results were related to the increase in the degradation of fiber fractions. There were higher EL (p = 0.0062) as a function of enzyme levels and aerobic deterioration after silo opening, at all levels tested. Thus, it can be concluded that the exogenous fibrolytic enzymes change the chemical composition of elephant grass silage, and increase its digestibility and nutritional value. Moreover, when used alone as an additive, fibrolytic enzymes are not able to recover all dry matter of this silage (with effluent and gas losses), and are not able to maintain aerobic stability in the first hours after opening the silos.

By Products

Surimi processing industries generated over 60% of fish by-products, including head, skin, viscera, trimming, bone, scale, and fin. Hence, an effort converting these by-products into valuable compounds and constituents is necessary for optimizing the resources. In order to implement this, the information on the chemical composition of the by-products is helpful. This study aimed to determine the chemical composition, particularly minerals of lizardfish surimi by-products. The protein, fat, ash, moisture, and carbohydrate values of by-products differed significantly (p < 0.05). Protein content was highest in the skin and scale (29.63% and 29.62%, respectively), and ash content was predominantly found in the scale (28.43%), fin (26.01%), and bone (23.58). Calcium, magnesium, potassium, and sodium content were significantly varied respectively from 0.25% to 6.88%, 0.06% to 0.37%, 0.01% to 0.09%, and 0.01% to 0.32%. Calcium is highest in scale, whereas zinc, manganese, and iron were most abundance in all parts of the by-products sample. Zinc is mostly detected in the fin (76.75 µg/g), bone (48.67 µg/g) and scale (46.01 µg/g) parts. On the other hand, copper, chromium, selenium, cadmium and lead were detected at lower concentration (less than 2 µg/g), and complied with the safety levels set by the Malaysian Food and Regulations. These findings suggest that, by-products generated from lizardfish surimi processing may be used as ingredients to enrich nutritional value of other food products.

The Impact

Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality. In the present study, a field experiment was carried out to evaluate the effect of various forms of fertilization on crop performance and the nutritional value and chemical composition of two potato varieties (cv. Spunta and cv. Kennebec). For this purpose, five different fertilizer treatments were applied namely: control (C), standard fertilizer (T1), standard fertilizer + zeolite (T2), manure (T3) and slow release nitrogen fertilizer (T4). According to the results, it was observed that slow release treatment (T4) achieved the highest yield for both varieties, while the control treatment presented significantly lower yield compared to the studied fertilization regimes. The dry matter of leaves and shoots was higher in T1 treatment for cv. Kennebec and in T2 and T4 treatments for cv. Spunta, whereas the control treatment presented the highest dry matter content in tubers for cv. Kennebec and T2 and T3 treatments for cv. Spunta. A significant effect of the fertilization regime was also observed on the nutritional value of tubers and more specifically the protein, ash and fat content was increased by treatments T1 and T4, while carbohydrate content was also increased by T3 and T4 treatments for both varieties. Similarly, the total sugars, organic acids, β-carotene and lycopene content was increased in T3 treatment for the Spunta variety, while the antioxidant capacity showed a varied response depending on the fertilizer regime and the tested variety. In conclusion, the fertilization regime has a significant effect not only on the tuber yield but also on the quality of the final product and should be considered as an effective tool to increase the added value of potato crop.

The objectives of this study were to determine the chemical composition and dry matter digestibility of Quercus resinosa leaves harvested at different seasons of the year and to assess the intake and palatability of lamb diets containing foliage of Q. resinosa. There were three sites of collection, two located in the state of Jalisco and one in the state of Zacatecas, México. The young leaves harvested in spring, had greatest (P >0.05) nutritional value than leaves harvested in other seasons. The in vitro digestibility of organic matter (IVOMD), rapidly degradable fraction (a) and the degradation rate (c) were greater (P >0.05) in leaves harvested in spring and winter. The slowly degradable fraction (b) was greater (P >0.05) in spring, summer and autumn, and lesser in winter. The potential degradation fraction (a + b) and the effective degradability of dry matter were maximized (P >0.05) in spring than in the other seasons. The consumption was similar (P >0.05) among diets with different inclusion levels of leaves, but sheep consumed greater (P >0.05) amounts of diet containing leaves collected in spring. In conclusion, the Q. resinosa foliage contains the nutritional value and the digestibility and palatability that makes it suitable to replace completely the forage in the fattening diets of sheep, being preferable to use leaves harvested in spring and winter.

Two experiments were carried out in order to study the effect of the ash content of poultry litter (PL) on its nutritional value. In Expt 1, broiler PL was incorporated in the proportions of 30 and 45% into diets based on wheat straw supplemented with 20% maize grain. The PL was either fresh (containing 19% ash) or had been heated in a stack (giving 26% ash). There were also two additional diets containing 45% fresh PL to which either ground limestone or wood ash had been added to provide the same ash content as the diets containing 45% stored, high ash PL. An in vivo digestibility and nitrogen balance trial was carried out. Storing the PL, which resulted in heating and an increase in ash content, reduced dry matter intake significantly. The largest and most significant effect on the digestibility of dry matter, organic matter and crude protein can be ascribed to the freshness of the PL. Stored, heated PL had a highly negative effect on crude protein digestibility and on nitrogen retention. No negative effect of adding extrinsic ash was recorded. In Expt 2, the nutritional value of layer PL (LPL), compared with that of broiler PL (BPL), was examined using ten beef cows before and after calving. The diet was composed of 45% PL, 35% wheat straw (WS) and 20% maize grain. Daily dry matter intakes were 12·7 and 16·2 g/kg liveweight (LW) before calving and 15·5 and 22·8 g/kg LW after calving, for cows fed LPL and BPL, respectively. Owing to the combined effect of the lower dry matter intake, lower gross energy content and lower digestibility of LPL, the digestible energy intake of BPL diets was almost three-fold, and nitrogen absorption (g/kg LW0·75) on the BPL was 2·4-fold higher than on the LPL diets. Because the ash intake of both diets was similar, it is suggested that the main inhibiting factor of intake after calving was the rumen's ability to mobilize the large amounts of ash-rich complexes of ash and organic matter to the reticular omasal orifice and, consequently, out of the rumen.

This study evaluated the effects of the rehydration and ensiling of corn grain with two geometric mean diameters (GMD) of 0.55 and 1.83 mm obtained by the diameter of the sieved used on the fermentation characteristics and chemical composition of the silage. The experimental design was completely randomized with two treatments and six replications, as follows: rehydrated fine-corn grain silage (RFS) and rehydrated coarse-corn grain silage (RCS). Ground corn was rehydrated with water to achieve moisture levels close to 350 g kg-1. There was no effect on the dry matter recovery, though the recovery rate was high, with values greater than 97% in both silages. The particle size influenced the fiber content, with lower values in the RFS. The acetic and lactic acid concentrations were higher in the RFS, but the pH of the silages did not change. Oxygen exposure changed the pH of silages to 4.25 and 4.38 for RFS and RCS, respectively. After opening the silos, the silages showed high aerobic stability after 90 hours, which resulted in lower deterioration and lesser loss of quality. The geometric mean diameter of corn grain affects the silage fermentative profile and nutritional value.

Abstract Introduction. Foodstuffs of special nutritional use and dietary supplements, especially in the case of sportsmen, have been known and widely used in human nutrition, nourishment, and convalescence for many years. Aim. The aim of the study was to assess the nutritional value of two groups of special dietary formulations and, in particular, to compare the nutrient and energy content declared by producers with that revealed by the present analyses. Material and methods. The nutritional value of two groups of formulations was assessed. The first group comprised formulations for undernourished subjects or those with contraindications to use diets with normal content of proteins and/or fats. The second group of formulations included products intended for strengthening the organism and targeted mainly at sportsmen. Samples of purchased products were analyzed for the content of basic components: dry matter, total protein, crude fat, crude ash, and structural carbohydrates. The content of carbohydrates and energy value was calculated mathematically. Additionally, the content of selected minerals (calcium, potassium, sodium, magnesium, iron, zinc, copper, manganese) was determined. Results. The content of carbohydrates, proteins, and especially fat in the chemical composition of the analyzed products declared by the producers differed from the levels determined in this study. In the mineral composition, differences were noted in the content of macroelements, while the content of micronutrients did not differ from the declared values. Despite the differences in the composition, the declared and calculated calorific values in all formulations were similar. Conclusions. There were differences between the declared and determined contents of nutrients in the analyzed formulations. The labels of the special-purpose industrial formulations purchased in pharmacies provided more information about their composition and nutritional value, whereas the information presented on the labels of the athlete supplements were less informative. Consumption of the supplements, in particular those dedicated for sportsmen, should be supervised by a doctor or dietitian.
