Beet Pulp

The influence of different doses of natural zeolite addition on chemical composition and quality of beet pulp silages was investigated. Beet pulp was ensiled in the sugar factory in Pozarevac immediately after they were obtained, or after 9 or 17 days. The two-factorial trial was conducted where the first factor (A) was the time of ensiling expressed in days after the pulp was obtained (a1= O; a2 = 9; a3 = 17), while the second factor (B) was the amount of zeolite added (b1= 0; b2 = 0.05; b3 = 0.25 and b4 = 1.25% in dry matter or 0; 50; 250 and 1250 g zeolite per 100 kg of raw beet pulp). Sample collection for standard chemical composition and quality estimation was taken 60 days after the beginning of the ensiling. The results from the literature show that adding technologically processed natural zeolite (Min-a-Zel, produced by ITNMS, Belgrade) while ensiling beet pulp has significant influence on the increase of lactic acid production, decrease in bonded acetic acid content and lower pH value. The influence of explained doses of zeolite on standard chemical composition is smaller and mostly of relative value. The only real changes in chemical composition are the increase in dry matter and mineral content. In the ensiling of the beet pulp stored in the longer period of time, the more intensive fermentation processes were achieved and the production of organic acids was larger which has better conserving effects on silage.

Beet Pulp

This study deals with effects of pressing of ensiled sugar-beet pulp and of application of a chemical preservative on the quality of fermentation process. The experimental silages had a better sensory evaluation than the control ones. In silages treated chemically with a mixture of acids, statistically significantly (P < 0.01) higher dry matter content, lowest pH value, the value of lactic acid and the lowest content of all acids in dry matter were found after 180 days of storage from the beginning of the experiment. The statistically significantly (P < 0.01) highest lactic acid content (43.39 ± 1.25 g/kg DM) was determined in the control pressed silage. The highest LA/VFA ratio (1.40 ± 0.18) was calculated for non-pressed experimental silage (D – 3 l/t of KEM). As compared with untreated control the highest percentage (P < 0.01) of lactic acid and of all fermentation acids was found out in silage D treated with 3 l/t of KEM (58.18 ± 0.47 g/kg DM). Undesirable butyric and propionic acids were not found in chemically treated silage samples (C, D, E, F). However, the highest (P < 0.01) contents of butyric acid (26.37 ± 0.91 g/DM) and propionic acid (4.58 ± 0.78 g/DM) were measured in untreated non-pressed silage samples (B). The highest (P < 0.01) contents of acetic acid and ethanol were found in control silage samples. The quality of these silages was evaluated as very low.

Studies were carried out on the main indicators of the chemical composition and physical properties of muskulus longissimus dorsi of pigs of different genotypes during hybridization. The indicators of the chemical composition and physical properties of muskulus longissimus dorsi were determined by conventional methods. The materials of experimental studies were processed using methods of variation statistics. According to the amount of moisture, no significant difference between the control and experimental groups was established. According to the amount of protein in meat, a tendency to a slight decrease, compared with the control group by 1.4 (group III) … 1.9 % (group II) was established. The use of boars of Poltava meat breed led to a decrease in intramuscular fat in descendants by 0.25 % compared with peers of a large white breed (P <0.95), and precocious meat - to a real increase of this indicator by 0.43 % at P> 0 , 95. A tendency towards an increase in the amount of tryptophan (by 0.04 ... 0.05) and oxyproline (by 0.004 ... 0.005) in the muscles of hybrid animals was revealed in comparison with peers of pure breed of large white breed. In terms of the biological usefulness of meat proteins, animals of group III were the best - in terms of the quality of the protein of the longest muscle of the back, their advantage over peers of group II was 0.07, and compared with purebred peers. Group I - 0.12 (p <0.95). It was found that with the same area of the meat spot both in purebred large white breeds of animals and hydrides of different genotypes, there is a tendency to increase the latter compared to the control in a humid place: with a «share» of «blood» ½ pm by 2.2 %, and with a «share» of blood ½ cm - 1.4 %. A tendency has been established to increase the pH value of the longest back muscle in animals with a «share» of blood of specialized meat breeds compared with a large white breed. In hybrid animals with a «share» of blood of Poltava meat and precocious meat breeds, there is a tendency to increase the pH value in comparison with the large white breed by 0.15 (2.8 %) and by 0.17 (3.1 %), i.e. the meat of hybrid pigs, the pH of which has a shift towards alkalinity due to less accumulation of lactic acid, has a worse preservation.

The effects of spring-applied nitrogen (0, 56, 112 and 224 kg/ha) and phosphorus (0 and 27.4 kg/ha) on the dry matter (DM) yield and forage quality of successive harvests of meadow foxtail (Alopecurus pratensis L.) were investigated. Nitrogen increased DM yield, crude protein, Cu, K and Zn contents and decreased P, Ca, Mg and Mn contents. Application of P in combination with N increased K content in the first cut and arrested the decline of P content due to N application in all cuts. The levels of dry matter digestibility and Cu declined in successive cuts whereas Mn content increased. At low N rates, Ca and Mg contents increased as the season advanced.

The aim of the work was to evaluate the effect of addition of humidity absorbent (malt sprouts) and chemical conservation additive on fermentation process quality of brewer grains’ silage. Chemical conservation additive was based on formic acid, propionic acid, benzoic acid and ammonium formate content. In a model experiment the fresh brewer grains were used. A dry matter (DM) content of brewer grains was 187.4 g / kg. Six treatments with three repetitions per treatment were prepared. The treatments A1, A2 and A3 were not supplied by humidity absorbent. Treatment A1 was a control treatment without any additive. The treatments A2 and A3 were supplied by chemical conservation additive in a dose of 3 L per tonne and 6 L per tonne, respectively. The treatments B1, B2 and B3 were supplied by malt sprouts to reach DM content of conserved matter on level 320–350 g / kg. Moreover the treatments B2 and B3 were supplied by chemical additive with its dose 3 and 6 L per tonne. Model silages were evaluated after 8 months of conservation at average laboratory temperature 26–28  °C, from each treatment were the final laboratory samples taken and analyzed. During conservation of treatments B1, B2 and B3 were no drain recognized. From A1 treatment drained 1300 ml of waste fluid that is 145 L per tonne of conserved matter. That was significant (P < 0.01) the malt sprouts addition support the lactic acid production and eliminate acetic acid production. There was no propionic acid or butyric acid detected in silages with malt sprouts event in these silages were analyzed higher (P < 0.01) concentration of ammoniac. Chemical additive supplementation improved (P < 0.01) the pH value and water leach acidity. The results show the malt sprout addition eliminates waste fluid drain and improves fermentation process. The higher concentration of chemical additive (6 l / t) inhibited the fermentation process in our model experiment.

Ssf Process

Solid state fermentation (SSF) represents a technological alternative for a great variety of legumes and cereals, or combinations of them, to improve their nutritional quality and to obtain edible products with palatable sensorial characteristics. Chickpeas (Cicer arietinum L.) are prone to develop the hardening phenomenon, also known as hard-to-cook (HTC) defect, when stored under adverse conditions of high temperature (≥ 25 °C) and high relative humidity (≥ 65%). This hard-to-cook phenomenon causes increases in cooking time, decreases in nutritional quality and deterioration of sensorial attributes of chickpea. The objective of this work was to study the effect of SSF on chemical composition and nutritional quality of fresh and hardened chickpeas. The hardening of chickpea ( Cicer arietinum L. Blanco Sinaloa 92 variety) for human consumption, was produced by accelerated storage (33-35 °C, RH = 75%, 180 days). A Rhizopus stolonifer spore suspension (1 x 106 spores/mL) was used as starter for the fermentation. The temperature and time of the SSF process were 35.8 °C and 42.7 h, respectively. The tempeh was obtained from fresh and hardened chickpea. The SSF process caused a significant increase ( p ≤ 0.05) in crude protein, true protein (19.6-19.9 to 23.2-23.4%), protein solubility, in vitro digestibility (68.6-73.1% to 79.9-80.5%), available lysine (2.19-3.04 to 3.19-4.07 g lysine/ 16 N), palmitic acid, and stearic acid, and a significant decrease ( p ≤ 0.05) in lipids, minerals, linoleic acid, phytic acid (8.82-10.73 to 2.11 g phytic acid/g dry matter), and tannins (16.1-22.4 to 3 mg catechin/g dry matter). The SSF process improved significantly the quality of fresh and hardened chickpea.

Research was conducted to determine the quality and chemical composition of silages obtained by mixing in different ratios of narbonne vetch (Vicia narbonensis L.) and barley (Hordeum vulgare L.) grown in rabi season of 2017-2018 in Eastern Anatolia, Turkey. In the study we studied the pure sowings of barley and narbonne vetch and their mixtures (20, 30, 40, 50, 60, 70, 80% of narbonne vetch (N) + 80, 70, 60, 50, 40, 30, 20% of barley (B). The values of ADF (acid detergent fiber), NDF (neutral detergent fiber), DDM (digestible dry matter), DMI (dry matter intake), DM (dry matter), CP (crude protein) and RFV (relative feed value) of silages of analyzed were respectively 33.38, 33.73, 62.89, 3.57, 24.69, 15.50%, 174.64. We also founded that LA (lactic acid), AA (acetic acid), BA (butyric acid), PA (propionic acid) and Ca, P, Mg, K and pH of silages investigated were respectively 1.60, 0.57, 0.42, 0.06, 1.17, 0.53, 0.25, 3.51% and 3.80. Our results shows that silages with high narbonne vetch were higher quality values for CP, ADF, NDF, DM, RFV, DDM, DMI, Ca, Mg, LA which determined chemical composition and feeding quality of silages. As a result, it is suggested that mixture silages with narbonne vetch (80%) and the barley ratio (20%) have important advantages for some properties of silages.

Mehdi, Y., Clinquart, A., Hornick, J.-L., Cabaraux, J.-F., Istasse, L. and Dufrasne, I. 2015. Meat composition and quality of young growing Belgian Blue bulls offered a fattening diet with selenium enriched cereals. Can. J. Anim. Sci. 95: 465–473. The objective of this study was to evaluate the effects of selenium (Se) enrichment of cereals on the performance of Belgian Blue bulls, meat quality and chemical composition. Twenty-three bulls were used in the present study. Twelve bulls were offered a control diet containing Se at a basal concentration of 58 µg kg−1 of dry matter (DM) and the other 11 bulls were given a diet containing 173 µg kg−1 DM of Se by means of Se-enriched spelt and barley. The Se enrichment of the diet did not affect the growth performance, the slaughter data or meat quality (P > 0.05). There were no effects of Se on tenderness, oxidative rancidity and water losses. However, there were some effects of Se enrichment on the meat chemical composition. The ether extract was decreased from 2.1 to 1.7% DM (P<0.05). There was also significant Se enrichment (P<0.001) in the longissimus thoracis muscle (177 vs. 477 ng g−1 DM) and organs: liver (474 vs. 1126 ng g−1 DM) and kidney (4956 vs. 5655 ng g−1 DM), Under such conditions, the human consumption of a piece of such meat or liver can provide a large part of the recommended daily Se intake, estimated between 30 and 57%.

The study was conducted to investigate the nutritive value and microbial status of different wholesale cuts of sheep carcass. The meat sample was obtained from 3 sheep. The ages of sheep were approximately of 1, 2 and 3 years. The wholesale cuts were shoulder, rack, loin and leg of each sheep carcass. The pH, juiciness, chemical composition, total bacteria, coliform bacteria, yeast and mould were studied to assess the quality of meat. The range of pH value were 5.077 - 5.927. The value of juiciness was decreased with the age. The value of dry matter, ash, crude protein, ether extract, calcium and phosphorus content of all samples were ranged from 23.32-30.40%, 0.88-1.027%, 20.50-24.88%, 8.10-12.13%, 0.012-0.038% and 0.048-0.185% respectively. Statistical analysis indicated that the value of pH, juiciness, dry matter, crude protein, ether extract, calcium, phosphorus and yeast (log value) was highly significant (P< 0.01) due to age and cut. Chemical composition, such as dry matter, ash, ether extract and calcium of all the samples increased gradually with the age, except crude protein, which decreased gradually with the age. The phosphorus content of the sample did not differ significantly due to age and cuts. The value of ash content was less significant (P<0.05) due to different cuts but highly significant (P<0.01) due to age. The range of total bacteria and coliform bacteria was 4.210-4.787 and 2.38-3.637/g of sample respectively. The range of yeast was 1.297-2.777/g of sample. Different meat cuts and ages did not show significant difference on total bacteria and coliform bacteria but in case of yeast, the value was highly significant (P<0.01) for the ages and cuts. Nutrient content of mutton varies due to different wholesale cuts as well as age. DOI: http://dx.doi.org/10.3329/bjas.v37i1.9865 BJAS 2008; 37(1): 32-38
