Coconut Coir

As a first step in assessing the viability of periphyton-based shrimp production in lined pond aquaculture systems, the effects of natural substrates (split bamboo poles and coconut coir) on development of periphyton were evaluated. Experiments were conducted in outdoor earthen lined pond to study periphyton biomass on two types of natural substrates such as split bamboo pole and coconut coir which was placed inside the earthen lined pond filled with seawater for duration of 45 days. The periphyton biomass was recorded at 0–40 cm depth, 40–80 cm depth and 80–120 cm for all the substrates. The periphyton biomass, in terms of dry matter (DM) from coconut coir was comparatively higher (3.4995±0.3120 mg cm-2) than the split bamboo poles (3.2011±0.3044 mg cm-2) during the experiment. ‘T’ test has affirmed that significant difference (p<0.05) was observed in the dry matter content of the periphyton among the substrates. ‘T’ test analysis of the data relating to periphyton biomass for split bamboo pole and coconut coir recorded at different depths indicated that upper 0–40 cm depth had higher values than the other depths. Furthermore, among the two substrates, coconut coir (3.4995±0.31201 mg cm-2) was observed to be a better substrate than the split bamboo pole for periphyton biomass production. Coconut coir substrate can be utilised by fin and shellfishes as natural food.

A study was made of whether the dry matter content of silage influenced performance when 17-month-old male reindeer were fed solely silage outdoor during winter. Two kinds of round-baled silages with different wilting times were offered to the animals; low dry matter (LDM silage) with a mean of 39% DM, or high dry matter (HDM silage) with a mean of 53% DM. The 115 reindeer were allotted to slaughter at the start of the experiment in October or to be fed until slaughter in January or March. During the first three weeks of the experiment small amounts of lichens were mixed with the silages and the reindeer adapted to the feeding without problems. The daily intake of DM did not differ significantly between reindeer fed the LDM or the HDM silage despite a highly significant difference in daily silage intake. This resulted in small but significantly higher gains in live weight for animals fed the LDM silage, caused by increased weight of the rumen content. All groups of reindeer either retained or lost carcass weight during the experiment, and no improvements or differences were obtained between the kinds of silages in carcass assessment or gains in fat in the abdominal cavity. Animals slaughtered in January had a lower carcass weight and dressing percentage than reindeer slaughtered in October and March. Environmental conditions during the experiment were good but nonetheless mobbing and illness still occurred. The present results concur with those of earlier studies suggesting that it seems to be the bulk of the ration rather than the dry matter content of the silage that limits the intake.

The aim of this study was to assess phenotypic diversity in terms of fruit quality traits and yield, and also to establish valuable genotypes for breeding purpose suitable for different direction of use. Ten cultivars of hot peppers bred at VRDS Buzau were collected and fruit quality (dry matter content, fruit firmness, the total soluble solids, titratable acidity and ascorbic acid content) was evaluated at different ripening stages. A very highly significant difference (p<0.01) was found for the studied quantitative parameters, showing a great variability among the studied accessions. During ripening, the dry matter content, the firmness, the TSS content and the titratable acidity increase for all studied cultivars and there were significant differences between them. A broad range of variation was noted in Vitamin C content in both stages of maturity. In the present research work, a great variability among the studied accessions was found. Fully ripe fruits were found considerably richer in the bioactive factor than unripe fruits. Our results have selected two important genotypes: A12A, an accession suitable for obtaining chili powder, due to the his low content in dry matter and total soluble solids and accession A135 suited for fresh consumption and for long shelf life because it has a high firmness.

Various modes of edible coating application vary in their coat dispersion and film formation, hence the need to determine the most effective mode of application for cassava. Edible surface coatings have been found to be effective in preserving the quality of various food products. However, there are variations in effectiveness among the different coating solutions, hence the need for optimization of the concentrations of the gums used. This study aimed at determining the most efficient coating application method on the cassava postharvest quality. Physiologically mature cassava (variety KME 1) was harvested and divided into seven portions. The various portions were coated using 1.5% xanthan gum, 1.5% xanthan/guar gum, and 2% xanthan/guar gum by both dipping and spraying method. There was no significant difference on the colour, total cyanide, ethylene production, and total phenolic content between the two application methods. The 2% xanthan/guar gum coating showed a significant difference on the dry matter content while the 1.5% xanthan gum coating had a significant difference on the respiration rate and weight loss. The 1.5 xanthan treated roots had a final dry matter content of 72.5% for the sprayed samples and 75.98% for the dipped sample while the 2% xanthan/guar gum treated roots had a final dry matter content of 64.6% and 74.1% for the dipped and sprayed root samples, respectively. The 1.5% xanthan and 2% xanthan/guar gum treated roots showed no significant difference in their action on dry matter content. The 1.5% xanthan/guar dipped and sprayed samples differed significantly on their effect on flesh firmness with final values of 35.4N and 46.1N, respectively, at 20 days after harvest. This study suggested that based on the coating solution and the parameters being observed, there generally was no varying effect of dipping and spraying methods of coating application. The choice of the efficient mode of application to use will depend on other factors such as the easiness of application.

Vegetarian Diets

Pet owners are increasingly concerned about the links between health status, animal welfare, environmental impacts, climate change and consumption of animal products. Accordingly, many owners are increasingly interested in vegetarian diets for themselves and their companion animals. However, such diets should be investigated nutritionally regards digestibility as well as on fecal quality and nitrogen output. In light of this trend, six Beagle dogs were included in a cross-over experimental design and offered a vegetarian diet containing wheat gluten (8.81%), rice protein (8.81%) and sunflower oil (6.84%) or an meat-based diet containing poultry meal (19.5%) and poultry fat (5.23%). The dogs received extruded complete diets for 12 days (adaptation and collection period, each 6 days). The dogs fed both diets showed a high and identical palatability (scoring of food intake) of the experimental diets. No significant differences occurred regarding digestibility of organic matter, crude protein and crude fat between vegetarian and meat-based diets. However, dogs fed the meat-based diet had higher (p < 0.05) nitrogen-free extract digestibility (89.5%) compared to those fed the vegetarian diet (88.6%). The amount of nitrogen excreted in feces (g)/kg BW0.75 was slightly, but not significantly, higher for dogs fed the vegetarian diet compared to those fed the meat-based diet (0.88 vs 0.79). The fecal consistency scores were considered to be within an acceptable range (well formed and firm). The mass of the feces between both groups were similar (62.9 g wet feces/100 g dry matter food) for vegetarian and meat-based diets. Additionally, the fecal dry matter content was comparable between both groups (29.0% and 29.6% for vegetarian and meat-based diets, respectively). In conclusion, the results of this study appear to indicate that virtually the only significant difference between the two diets was lower nitrogen-free extract digestibility in the vegetarian diet. However, the vegetarian diet did not result in a significant difference in amount of nitrogen excreted in feces.

The research was undertaken to determine the amounts of precipitate formed in the milk plasma due to mixing of different levels of heated milk with raw milk, and to establish a turbidity index, which will be helpful as a field method in detecting the extent of addition of heated milk. The tests were conducted on five different treatments namely, Milk sample A (100% Heated milk), Milk sample B (75% Heated milk + 25% Raw milk), Milk sample C (50% Heated milk + 50% Raw milk), Milk sample D (25% Heated milk + 75% Raw milk) and Milk sample E (100% Raw milk). Samples were examined by chemical analysis including fat content, protein content, dry matter content, ash content, pH, acidity, turbidity test, and precipitation content of plasma. There was a highly significant difference (p<0.001) in case of fat, protein and precipitate contents of plasma as affected by extent of addition of heated milk. A statistically significant difference (p<0.05) was also found for ash content. On the other hand, no significant difference was found in case of dry matter content, pH and acidity of milk. A strong correlation (R2=0.819) was observed between the amount of precipitate and proportion of heated milk mixed with raw milk. A field method was devised on the basis of extent of turbidity, which was in fact amount of precipitate formed in the milk plasma as a function of extent of the addition of heated milk to raw milk.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20708 Bang.

Dry matter content is one of the important characteristics of sweet potatoes in addition to high yield. The aim of this study was to evaluate the performance of promising sweet potato clones for higher root yield and dry matter content. A hundred promising sweet potato clones were evaluated and arranged in randomized block design with two replication. The variables observed included: weight of vine, harvest index, number of root per plot, the weight of root per plot, dry matter content, root yield, root skin color, and flesh color. The analysis of variance showed a significant difference among the tested genotypes in all traits observed. A hundred promising sweet potato clones showed that root yield has varied ranged from 4.88–41.38 t h-1 with an average 20.28 t h-1 and dry matter content ranged from 19.19 – 40.65% with an average 30.47%. Fifteen promising clones of a hundred clones tested had high root yield and dry matter content with varying color flesh.

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01) but no significant difference was recorded for dry matter content of egg yolk at 50% level of egg production (P>0.05). The CP contents of egg albumen and egg yolk differed significantly (P<0.01) at 50% level of egg production but the difference was not significant (P>0.05) for CP content of egg yolk at 75% level of production. There were significant differences (P<0.01) on EE and TA contents of egg albumen and egg yolk at all levels of production. The results of the study demonstrated that the dry matter, as well as crude protein, ether extract and total ash content of eggs on dietary treatment T1(Scavenging + standard ration) was highest compared to the eggs on other treatment groups (T0, T2, T3, T4 and T5).

The experiment was condunted at the Alfredo Volio Mata Experimental Station of the University of Costa Rica, located at 1542 meters above sea level. The purpose was to determine the effect of plant density on total forage mass and the nutritive value of corn. Three diferent plant distances were used: 30 x 70 cm, 50 x 70 cm and 70 x 70 cm resulting in 47619, 28600 and 20449 plants per hectare, respectively. The first sampling was taken out 42 days after establishment and every two weeks thereafter, until 126 days. Dry matter, crude protein, ashes, neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin were analyzed for different parts of the plant. The values for celulose and hemicelulose were calculated. Total forage mass (kg/ha) was greater at higher plant densities. Dry matter content of leaves was higher than in stems, all of the plant densities. No significant difference (P<0,05) was found for crude protein content in the different parts of the plant. ADF was always higher in stems than in leaves. Stage of growth considerably affects biomass yield and nutritional quality of fodder. Before 70 days the dry matter content in leaves was higher than in stems. Latter accumulation of dry matter in stems was greater than in leaves. Crude protein content in leaves was over 18% during the first 70 days, then decreases a level of 13% at the end of the period. The lowest value of ADF was found before 84 days in leaves and stems. Under the enviromental conditions of this experiment, it appears that plant densities of about 48000 plants per hectare are optimal.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.
