Dry Matter Content

Sixty-four 12- to 24-hour collections were made of digesta flowing from re-entrant ileal fistulas of two pigs used to study the digestibility and rate of passage of various materials in the proximal digestive tract. An average of 88 per cent of the digestible dry matter and 91 per cent of the digestible protein of a 20 per cent protein ration was digested in the stomach and small intestine. The ration was very finely ground and fed only for short periods. The dry matter content of the fistula digesta was considerably higher when the concentrate ration was fed than when dried skim milk powder or various soluble carbohydrates were fed. Glucose was the most completely digested of all carbohydrates tested, usually followed in decreasing order by corn starch, galactose, sucrose, lactose and potato starch. Undigested soluble carbohydrates were accompanied by large volumes of fluid which seldom exceeded isotonic concentrations. Undigested potato starch resulted in digesta which at times contained 42 per cent dry matter. Fats fed with dried skim milk were well digested with maximum digestion coefficients of 91 recorded for corn oil and 84 for tallow. There were few changes in the composition of the digesta flowing from the fistula at various times of the day but there was a significant increase (P <.01) in the protein and ash content from the first to second 6-hour interval after feeding dried skim milk.

Non-meat ingredients are used to impart flavor, slow bacterial growth, and increase the yield of the sausage production. To study the quality of chicken sausage incorporated with non-meat ingredients namely, soy protein powder, non-fat milk powder and potato starch at the rate of 2% (w/w) concentration. Sausage samples were analyzed for physical, nutritional, and sensory properties during refrigerated storage at -4 ℃. The nutritional, physical and sensory characteristics were analyzed, at day 1, week 1, week 2 and week 3 of storage. Moisture, ash, dry matter, fat, pH, texture, and color were significantly difference (p<0.05) among the treatments at day one. During storage the ash, pH content and dry matter content were significantly (p<0.05) increased, and fat content and moisture content was significantly (p<0.05) decreased storage period. At week one, the higher hardness value showed in soy protein powder incorporated chicken sausage and least value showed in without added non-meat ingredient (control) sausage. As results of organoleptic characteristics revealed that, 2% of potato starch incorporated chicken sausage had the highest mean score of overall quality of all sensorial properties namely, color, taste, texture, flavor, and overall acceptability.

Skim milk powder reconstituted to 8.44% TS, 9.65% TS and 10.84% TS respectively was used for investigation. Untreated milk and milk heat treated at 85?C/20 min and 90?C/10 min, respectively, were used for the investigation. Milk was inoculated with 2.5% of yogurt culture (containing Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus in the ratio 1:1) at 43?C. Samples were incubated until pH 4.6 was reached. Samples were immediately cooled to 4?C and held at that temperature during 14 days. Acid casein gel was stirred after 1, 7 and 14 days of storage. Measurements were done at 30 rpm during 2 min, at 20?C. According to the investigation, it could be concluded that both applied heat treatment and dry matter content influence viscosity of stirred yogurt. Viscosity increases when dry matter content increases. The smallest viscosity had yogurt produced from untreated milk with 8.44% TS, while samples produced from milk with 10.84% TS had the highest viscosity. Applied heat treatments had significant influence on viscosity of yogurt gained by stirring of acid casein gels after 7 and 14 days of storage. Stirred yogurt produced from milk heat treated at 90?C/10 min had a higher viscosity than samples produced from milk heat treated at 85?C/20 min. Storage period influenced average viscosity of stirred yogurt. Samples of stirred yogurt produced from milk with 8.44% TS showed a decrease of average viscosity during storage regardless of the applied heat treatment of milk. The highest average viscosity had samples produced from milk with 10.84% TS.

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were  evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five  treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia  nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and  reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.

Abstract The study is aimed at studying the effect of a microbiological preparation consisting of lactic acid bacteria, thermophilic streptococci and cellulolytic bacteria on the quality of alfalfa silage with different dry matter content. Determined pH, content of organic acids, dry matter and nutrients, including carbohydrates. Inoculant application increased crude protein, crude fat and crude fiber and reduced water-soluble carbohydrates in silage. The preservation of nutrients in the test samples was higher than that of the control. pH corresponded to optimal values; however, lactic acid fermentation proceeded more intensively in the sample with an increased dry matter content.

Crop Density

Morphological and physiological characteristics of an ideal genotype are described. High dry-matter yield is required and therefore the ideotype needs to have high crop-density tolerance and efficient photosynthesis. Low susceptibility to pests and diseases is important. A stocky stem would benefit intake, yield and lodging resistance but reduce digestibility and dry-matter content. Selection for root-lodging resistance might reduce whole-plant yield. Improvement of cellular contents is of little importance, but cell-wall digestibility could be improved without strongly affecting yield. To be of high nutritional value, the stover must have sufficient dry-matter content (30-35%) and a moderate level of water-soluble carbohydrates. The ideotype should have an early silking date, a large ear and a slow rate of grain filling. (Abstract retrieved from CAB Abstracts by CABI’s permission)

The process of adding soy lecithin to milk (lecithination), followed by the agglomeration stage and drying, are the goal to increase the powder dispersion in water. This work studies the physical characteristics of milk lecithinated by the addition of raw and clarified lecithins with hydrogen peroxide, which was dried by lyophilization. The main objective was to compare the behavior between the particles of powdered milk, added 0.4% (w/v), 0.8% (w/v) and 1.0% (w/v) lecithin raw and clarified. The amount of added soy lecithin was determined on the basis of dry matter content of the full UHT milk used in the experiment. Lecithinated of fluid milk samples were put on aluminum forms and frozen by contact with liquid nitrogen and were placed inside the lyophilizer chamber. The lyophilization stage was carried out for approximately 7 hours under vacuum of 460 mmHg and temperature of -38 ° C. Dried samples were fragmented in porcelain pestle and kept in oven at 40°C until analyses. The powder milk added with lecithin clarified had shorter wettability to the concentration of 1.0% (w/v), the lowest percentage of retained insoluble after solubilization in water and the micrographs of the powder showed that most adding more clarified formed lecithin agglomerates of the milk powder added lecithin raw. So, the lecithin clarified give improvements in the particles for the milk added.

Early Afternoon

The concentrations of water-soluble carbohydrate (WSC) and its components, starch, total nitrogen, and dry matter of phalaris (Phalaris aquatica L. cv. Australian) pasture were varied by shading for periods ranging from 38.5 to 46.5 h. In unshaded pasture, WSC concentrations were lowest at sunrise [103 mg/g dry matter (DM)] and increased until early afternoon (to 160 mg/g DM). Sucrose and starch increased in concentration during daylight, whilst the concentrations of glucose, fructose, fructan, and a component of WSC considered to be mainly the carbohydrate moiety of glycoside(s) were relatively constant. The concentrations of starch, and all components of WSC except sucrose, were reduced by shading, but increased to the concentrations observed in the unshaded pasture within 2–4 h after removal of the cover. The fructans present in phalaris were determined to be oligosaccharides of degree of polymerisation (DP) 3 and DP 4 and high molecular mass fructans with DP >10. Nitrogen concentration of shaded pasture was initially higher (4.7% DM) than in unshaded pasture (3.9% DM), but decreased after removal of the shade cover. Dry matter content was reduced in shaded pasture, partly due to increased retention of water on the exterior of plants. The experiment was a precursor for a grazing trial in which the WSC content of pasture was to be altered by shading. It indicated that shading would potentially alter WSC and N concentrations, and DM content, but would have only a relatively small impact on the digestibility of the pasture.

Chopped Grass

Thirty-two sheep (30.0 kg avg. BW) were used to study the effects of dry-matter (DM) content at harvest on the nutritive value of timothy grass silages conserved as round bales of high (52.1%, DM50), medium (39.9%, DM40) and low (23.1%, DM25) DM. Chopped grass of 24.4% DM conserved in a horizontal silo (HS) was used as a control. Gross energy, crude protein (CP) and acid detergent fibre (ADF) contents were similar for all silages (P > 0.05). Neutral detergent fiber (NDF) contents decreased as DM of the silages decreased (P < 0.05). Acid detergent lignin and ash contents were highest in HS and lowest in DM40 silages (P < 0.05). Silage pH and water-soluble carbohydrates decreased with decreasing DM of the silages (P < 0.05), while ammonia-N and lactate levels increased (P < 0.05). Acetate concentrations in round bales were lower than in HS silage (P < 0.05). Significant butyrate concentrations were detected only in DM25 silage. Round-bale silages were chopped before feeding and fed ad libitum. DM intake was 14.5% higher for DM50 and DM40 silages than for DM25 and HS silages (P < 0.001). Average daily gain and feed efficiency were higher for high-DM silages than for DM25 and HS silages (P < 0.01). Apparent digestibilities of NDF, cellulose and crude fiber of the silages were similar, but DM, organic matter, energy and hemicellulose digestibilities were higher for HS than for DM25 silage. Apparent digestibilities of ADF and CP were higher for high-DM silages than for DM25 and HS silages (P < 0.04). The results indicate that to obtain good-quality silage, the DM content of round bales should be 40–50%. The better performance obtained with high-DM silages was indicative of a more efficient utilization of metabolizable energy for gain. Key words: Round-bale silage, timothy, forage

Pre-ensiling treatments can significantly influence the composition of lucerne (Medicago sativa L.) silages (LS). Besides dry matter (DM) content and availability of water-soluble carbohydrates (WSC), wilting intensity may exert a strong impact on the crude protein (CP; nitrogen [N] × 6.25) fractions. The present study aimed to evaluate the effects of DM level, wilting intensity, and sucrose addition on N compounds and fermentation products in LS. Pure lucerne stand (cultivar Plato) was wilted with either high or low intensity to DM contents of 250 and 350 g kg−1, respectively, and ensiled with or without the addition of sucrose. Non-protein-N (NPN) concentration in LS was affected by all pre-ensiling treatments and with 699 g kg−1 CP, NPN was lowest in high-intensity wilted high-DM LS with sucrose addition. No effects were observed on in vitro-estimated concentrations of utilizable CP at the duodenum, a precursor to metabolizable protein. Sucrose addition and higher DM level decreased acetic acid and ammonia-N concentration in the silages. Therefore, the present study demonstrated the beneficial manipulation of CP fractions in LS by high-intensity wilting to higher DM contents and that the provision of WSC may be necessary for sufficient silage fermentation and protein preservation.
