Produce Acid

This study, using miniature silos, bas shown that sorghum cut at the booting stage can produce acid silage. Such early harvesting produced silage with a crude protein content of 10 per cent of its dry weight, did not significantly reduce the yield per acre of silage protein, but reduced the yield of silage by some 40 per cent. Sorghum cut before the booting stage failed to produce satisfactory acid silage. Thic could not he explained by low initial sugar contents. Also, a comparison of the fermentation behaviour over the range of crop maturities in miniature silos and water slurries suggests that physical conditions, such as moisture contents and the release of cell constituents, had little influence on the development of acidity.

Algal Products

The present experiment was designed to simulate an on-going field trial at Au Tau Substation, Agriculture and Fisheries Department, Hong Kong Government, using a series of fishponds to treat polluted riverwater, as well as for promoting algal growth, before the water was used for rearing freshwater fish. It was revealed that aeration was necessary to lower the level of ammonia. It also accelerated the conversion of ammonia to nitrite, and then nitrite to nitrate. Substantial amounts of metal (K, Mg, Cu, Zn) were also removed from the riverwater, possibly by algal assimilation. The algal products contained a high crude protein content (42% dry weight basis) which could be used to feed carp and tilapia.

Outdoor Experiments

The results of outdoor experiments with Lemnaqibba (a duckweed species) grown in mini-ponds proved to be highly competitive in comparison with other existing secondary treatment methods. The treated wastewater is at an acceptable level and can be reused for agricultural irrigation. The duckweed biomass, with a crude protein content of over 30% of dry weight, may be used as a protein rich alternative fodder. The ease of duckweed harvesting makes the potential treatment system even more economically attractive. Operational regime was controlled by the retention time and wastes depth. Retention time was in the range of 3 to 10 days, while the depths examined were 20 cm and 30 cm. The results indicate that shortening the retention time was associated with increase in protein content and did not affect the yield very much. The duckweed yield (dry basis) in the deep ponds (30 cm) was very similar to the 20 cm ponds, viz. around 14 g /m2 per day.

Flour Production

The  aim of this study was to evaluate the flour production for the evaluation of fish residues. This study was carried out in two experiments. The first was characterized by the production of flour from the filleting of abrótea fish, while in the second was used the shrimp residue. The treatments in both experiments consisted of two methods of dehydration: oven (T1) and microwave (T2), with four replicates per treatment. The moisture contents, ashes, total nitrogen and crude protein were evaluated. The results showed that flour production is an important tool for the evaluation of fish waste. The flour of Abrótea and shrimp are an important source of protein and minerals that can be used for animal feeding. The microwave method can be used in the preparation of fish and shrimp flours because it does not alter the crude protein content. The microwave is more advantageous than the oven because it speeds up the dehydration process of fish waste. The flour produced is an alternative for artisanal fishermen and can bring income to fishermen, fishers' families and also to poor communities.

Mischkolz, J. M., Schellenberg, M. P. and Lamb, E. G. 2013. Early productivity and crude protein content of establishing forage swards composed of combinations of native grass and legume species in mixed-grassland ecoregions. Can. J. Plant Sci. 93: 445–454. We evaluated the early establishment productivity of forage swards of native, perennial, cool and warm season grasses, and legumes as they have the potential to provide non-invasive, productive, and drought resistant rangelands. Seven species with agronomic potential and a broad native geographic distribution were selected for testing including: nodding brome [Bromus anomalus (Coult.)], blue bunch wheatgrass [Pseudoregneria spicata (Pursh)], western wheatgrass [Pascopyrum smithii (Rydb.)], side oats grama [Bouteloua curtipendula (Michx.)], little blue stem [Schizachyrium scoparium (Michx.)], purple prairie clover [Dalea purpurea (Vent.)], and white prairie clover [Dalea candida (Willd.)]. Forage swards, including all seven monocultures, 21 two-species mixtures and a mixture with all species, were planted in two sites, Saskatoon and Swift Current, Saskatchewan. Western wheatgrass (WWG) had the highest overall plant density and the strongest effect on the forage yield of the forage swards; however, productivity and crude protein content were not reduced when other species were also included in the forage sward. Dalea spp. did not establish as well as the other species, but had the highest crude protein concentrations. This work provides insight into forage sward development at the establishment stage; additional work is required to determine long-term species impacts for well established forage swards.
