SUMMARYExperiments were carried out to assess the effect of the following diets: unwilted and wilted silage, barn-dried hay and wilted silage and ensiled mixtures of grass and barley on the ruminal VFA patterns in sheep.There was a tendency for the unwilted silage to result in a slightly higher level of rumen acetate and a lower level of propionate than grass, wilted silage or barn-dried hay. In two of the experiments (Exps. 2 and 4) significant direct relationships were found between rumen acetate and the crude-fibre content of the diets and significant inverse relationships were found between the rumen propionate and the crude-fibre content of the diets.Significant relationships were also found between the rumen acids and the metabolizable energy content of the diets and in Exp. 2 there was a significant relationship between the rumen acetate and the water-soluble carbohydrate content of the diet.The addition of barley meal to grass produced different ruminal VFA patterns in sheep fed the ensiled material and the resulting silage.

Solenostemon monostachyus P. Beauv (Lamiaceae), it’s ethnomedical uses include anti-plasmodial, anti-pyretic, antiulcerogenic, antioxidant, anti-inflammatory and anti-nociceptive activities. The aim of this study was to employ the quality control parameters in the evaluation of the leaf and stem of Solenostemon monostachyus to aid in the identification and standardization of the medicinal plant. The plant leaves and stems were collected, identified, air-dried, pulverized and stored in separate glass containers. Standard procedures were employed to obtain the microscopic features of the fresh and powdered samples, micromeritic, chemomicroscopy, fluorescence properties, moisture contents, ash values and soluble extractive values. The results of the microscopic studies using fresh and powdered leaf samples revealed the presence of diacytic stomata on both the abaxial and adaxial surfaces (amphistomatic), with stomatal index of 27.9% and 14.8% respectively. The result of the micromeritics properties of the powdered leaf and stem samples showed angles of repose of 38.0o and 46.0o, Carr’s index of 23.7% and 32.5% and Hausner’s ratios of 1.3 and 1.5 respectively. Results for the moisture content, total, acid-insoluble and water-soluble ash values were 11.7%w/w, 13.7%w/w, 1.8%w/w and 9.4%w/w for the leaf and 13.3%w/w, 17.3%w/w, 1.8%w/w and 9.2%w/w for the stem respectively. Extractive values for water-soluble, methanol-soluble and ethanol-soluble were 26.5%w/w, 32.3%w/w, 14.5%w/w and 15.5%w/w, 15.8%w/w and 14.5%w/w for the leaf and stem respectively. Chemomicroscopy indicated the presence of lignin, calcium oxalate crystals and protein in the leaf and stem. The results obtained therefore could be used to establish pharmacopoeial standard for the fresh and powdered drug products of Solenostemon monostachyus, thus preventing adulteration.

First Time

Transmission and analytical electron microscopic studies of scale microstructures and microscopic marker experiments have been carried out in order to determine the transport mechanism in the oxidation of Ni-Al alloy. According to the classical theory, the oxidation of nickel takes place by transport of Ni cations across the scale forming new oxide at the scale/gas interface. Any markers deposited on the Ni surface are expected to remain at the scale/metal interface after oxidation. This investigation using TEM transverse section techniques and deposited microscopic markers shows a different result,which indicates that a considerable amount of oxygen was transported inward. This is the first time that such fine-scale markers have been coupled with high resolution characterization instruments such as TEM/STEM to provide detailed information about evolution of oxide scale microstructure.

Embedding Medium

The technique for using the water-soluble embedding medium glycol methacrylate has been improved for ultrastructural studies by the simplification of the method of formation of prepolymers used in embedding the tissue, by the addition of a cross-linking agent so that sections are stable in the electron beam, and by improving the softness of the blocks by the addition of a plasticizing agent. The preservation of tissue morphology has been improved by complete dehydration in glycol methacrylate monomer prior to infiltration with the prepolymer. Preservations of tissue morphology is further enhanced by complete dehydration in ethanols and embedding in the improved glycol methacrylate medium.

Crude Fibre Content

The Friesian cow in Indonesia gives about 1, 500 1. milk in about 240 days compared with 3, 800 1. in 300 days in the Netherlands. The author believes that the main reason for the low production in the tropics is not climate, but faulty feeding practices. A cow fed a typical Indonesian ration of reedy grass and fibrous concentrates gave 1, 003 1. milk in the first no days of her first lactation, but increased to 1, 870 1. in the first 102 days of her second lactation when given a diet containing much less crude fibre, in spite of the fact that the former lactation was in the wet and the latter in the dry season.

Crude Fibre Content

This investigation was conducted to determine the effect of organic fertilizers on the content of chlorophyll a, chlorophyll b, antioxidant activity, crude fibre, and zinc in two onion cultivars, Stuttgarter Riesen and Rote Laaer, during 2016, 2017, and 2018. In this research, the following treatments were used: B-Stimul (contains Azospirillum Tarrand et al., Azotobacter Beij., Bacillus Cohn, Chlorella vulgaris Beij., and Herbaspirillum Baldani et al.), EkoBooster 2 (contains biostimulators and mineral salts of nitrogen, phosphorus, and potassium) and Vermifit A (extract of compost of Californian earthworm). The results showed that the application of biofertilizers to onion resulted in the highest chlorophyll b content in 2017 in Stuttgarter Riesen. EkoBooster 2 positively affected crude fibre content in both cultivars, but only in 2016. Antioxidant activity was not significantly affected by the interaction of experimental factors. The application of the biostimulating fertilizers can have a positive impact on the quality parameters of onion, but the kind of fertilizer must be suited to seasonal conditions and the cultivar.

Propagule Size

The experiments were conducted at the Teaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso, Nigeria in 2010 and 2011 to determine the effect of propagule size and nitrogen levels on the growth and rhizome yield of ginger.The nitrogen source was from Tithonia compost (TC). Three propagule sizes were tested (20, 30 and 40 g) and seven nitrogen levels (0, 40, 60, 80, 100, 120 and 140g kg N/ha). The experimental pots were laid out in a randomized complete block design with three replicates. Data were collected on growth parameters (plant height, number of leaves, leaf length and leaf width); rhizome yield components (number of tillers and rhizomes, and rhizome weight and length); and proximate composition (crude protein (CP), crude fibre (CF), total lipid (TL); Total Ash (TA), Starch and water soluble extract). Data collected were subjected to analysis of variance and significant means were compared using Duncan Multiple Range Test (DMRT) (P ≤ 0.05). Propagule size, N levels and their interactions significantly (P≤ 0.05) influenced most of the parameters assessed. In most cases, the use of 30 and 40 g planting material gave similar results. Plants nourished with 140 kg N/ha significantly and consistently outperformed others fertilized with other nitrogen levels. Crude protein obtained from 40 g propagule size was significantly ( P ≤ 0.05) higher than other tested propagule sizes. The rhizome yields of fertilized plants were significantly higher than the non fertilized plants. Rhizome yields ranged from 1.57 t/ha in none fertilized plants to 3.71 t/ha in 140 kg N/ha. In conclusion, establishment of ginger with 40 g planting materials and its nourishment with 140 kg N/ha enhanced its growth, rhizome yield and proximate compositions of the plant.
