Number Of Leaves

This trial aimed at determining the dehydration curve at nine times (0, 3, 6, 9, 24, 27, 30, 33 and 46 hours after cuting of the plants); the leaf/stem ratio and number of leaves per stem in alfalfa submitted to four managements during the drying process. It was also evaluated the bromatologic composition and in vitro digestibility of the dry matter and cell wall of alfalfa hay before storage. The drying methods applied for alfalfa were the following: drying in the field until 50% DM and drying conclusion in an airy shed; drying in the field without turning; drying with only one turning and drying with two turnings. The experimental design was completely randomized with four drying methods and five replications. Leaf dehydration was faster when compared to the stems in all drying methods. Drying in the shed promoted the lesser re-hydration of the plants at night due to dew. It was also verified that alfalfa hays that remained under the sun and were turned showed the worst quality with reduction in crude protein contents and increase in NDF, ADF, NDIN and ADIN. However, in vitro dry matter digestibility and cell wall digestibility did not suffer any alteration because of the different dehydration methods (69.79 and 41.39%, respectively). There is a market fall of leaves and a reduction on the number of leaves per stem with the turnings.

Browse plants are under-utilized in the dry season because of the insufficient knowledgeabout the drying process that best helps to prevent degradation of nutrients available toruminant. The experiment was conducted to investigate the effects of drying methods (airdrying, oven drying and sun drying) on the chemical composition, in vitro digestibility ofleaves and leaves + twigs from (Albizia lebbeck, Albizia saman, Daniella oliveri,Enterolobium cyclocarpum, Gliricidia sepium, Leucaena leucocephala, Milletia griffonianaand Pterocarpus santalinoides). The leaves and twigs were dried under the three dryingmethods until constant weight and milled for in vitro digestibility. Gas production wasrecorded at 6, 12, 18, 24, 30, 36, 42, and 48 hours of the incubation period with 8x3x2factorial design using Duncan Multiple Ranged test. When the browse species werecompared, there were significant differences in the incubation hours while there were alsosignificant (P>0.05) differences for the plant parts in the incubation hours except at 3 hours.The value of short chain fatty acid (SCFA) μmol, ranged from 0.22 to 0.57, metabolizableenergy (ME) MJkgDM ranged from 2.72 to 3.25, while organic matter digestibility (OMD) %ranged from 38.44 to 50.48 respectively. Albizia lebbeck was highest (P<0.05) for SCFA,ME, OMD. It is concluded that drying methods had no effect on the forages considered.However, the leaves of these browse plants are highly digestible and their inherent nutrientsare higher than the range recommended for the maintenance in ruminant production.

Silicon (Si) is distributed throughout plant tissues, but its role in forages has not been clarified. Although Si has been suggested as an antiquality factor which limits the digestibility of structural carbohydrates, other research indicates that its presence in plants does not affect digestibility. We employed x-ray microanalysis to evaluate Si as an antiquality factor at specific sites of two cultivars of bermuda grass (Cynodon dactvlon (L.) Pers.). “Coastal” and “Tifton-78” were chosen for this study because previous work in our lab has shown that, although these two grasses are similar ultrastructurally, they differ in in vitro dry matter digestibility and in percent composition of Si.Two millimeter leaf sections of Tifton-7 8 (Tift-7 8) and Coastal (CBG) were incubated for 72 hr in 2.5% (w/v) cellulase in 0.05 M sodium acetate buffer, pH 5.0. For controls, sections were incubated in the sodium acetate buffer or were not treated.

Integrated Screening

There is a great need for the development of a rapid and reliable bioassay to evaluate the pulmonary toxicity of inhaled particles. A number of methods have been proposed, including lung clearance studies, bronchoalveolar lavage analysis, and in vitro cytotoxicity tests. These methods are often limited in scope inasmuch as they measure only one dimension of the pulmonary response to inhaled, instilled or incubated dusts. Accordingly, a comprehensive approach to lung toxicity studies has been developed.To validate the method, rats were exposed for 6 hours or 3 days to various concentrations of either aerosolized alpha quartz silica (Si) or carbonyl iron (CI) particles. Cells and fluids from groups of sham and dust-exposed animals were recovered by bronchoalveolar lavage (BAL). Alkaline phosphatase, LDH and protein values were measured in BAL fluids at several time points postexposure. Cells were counted and evaluated for viability, as well as differential and cytochemical analysis. In addition, pulmonary macrophages (PM) were cultured and studied for morphology, chemotaxis, and phagocytosis by scanning electron microscopy.
