A new liver biopsy instrument for large animals was manufactured and used to obtain samples in the range of 150–350 mg fresh weight from dairy cattle. Difficulties with the aspiration procedure caused by inadequate control of suction and excessively deep penetration of the liver were eliminated with the new instrument.

Gamma-hydroxybutyrate (GHB) is an illicit drug, which may be derived in plants from a stress-inducible metabolite known as gamma-aminobutyrate. Here, oxygen deficiency caused the accumulation of GHB in green tea and soybean sprouts (76 and 155 nmol g-1 fresh weight, respectively). These findings demonstrate that GHB levels are elevated in severely modified atmospheres, but they pose no risk to human health. Further work is required to assess the extent of this phenomenon.

The study was undertaken with a view to investigate the effects of different basal media and organic extracts on organogenesis of Dendrobium orchid. Protocorm like bodies (PLBs) were cultured in Knudson C (KC), Vacin and Went (VW), half strength Murashige and Skoog (½MS) and New Phalaenopsis (NP) media supplemented with Sabri banana pulp (Sb), Charcoal (C) and Coconut water (Cw) organic extracts. KC, VW, ½MS and NP media significantly influenced the plantlet regeneration of Dendrobium orchid. Among the media, ½MS showed better performance on fresh weight, number PLBs, shoots and leaves per plantlet, The longest shoots were found in KC medium and maximum length of leaves was found in both KC and ½MS media. In case of different organic extracts Sb showed significantly better performance on fresh weights of PLBs, number of shoot and leaves per explant, length of shoots and leaves.

Seed of four grass species was re-hydrated to 11 pre-determined moisture concentrations ranging from 100 to 600 g kg-1 fresh weight ( FW) to simulate seed maturation during swathing and combining. The performance characteristics of three thermogravimetric and two electronic capacitance methods of moisture determination were evaluated. The thermogravimetric methods had no moisture range limitations and were, in general, more accurate than the electronic methods. The thermogravimetric Koster tester is suitable for grass seeds of all moisture concentrations, and can be easily adapted for use at field sites. The John Deere Moisture- Chek electronic tester is suitable for the rapid determination of moisture in grass seeds but is limited to concentrations of 80–250 g kg-1 FW.

Indirect measurements of denitrification to 120 cm depth in a coarse textured soil in October showed higher denitrification rates following a single spring application of dairy cattle slurry than following a spring application of fertilizer. The highest denitrification rates occurred immediately above and below the water table (90 cm depth) and resulted primarily from C applied in the manure moving down through the soil profile.

The study was conducted at the USDA Biotechnology Laboratory, Department of Biotechnology, Bangladesh Agricultural University, Mymensingh during May to June 2006 to investigate the effect of different concentrations of IBA (0, 0.5, 1.0, 1.5 and 2.0 mg/l) with Vacin and Went (VW) medium and charcoal on root formation in Dendrobium orchid. Four parameters such as number of roots plantlet-1, length of root, fresh weight of root and days required for root formation were recorded at three DAIs (10, 20 and 30). The use of different concentrations of IBA had significant effects on the parameters examined. The best results were obtained from 1.0 mg/l IBA treatment in which the number of root was 1.81 plantlet-1, length of root 0.35 cm, fresh weight of root 0.16g at 30 DAI and the minimum days to root formation was 10.8.

Four linear furanocoumarins (psoralen, xanthotoxin, isopimpinellin, and bergapten) were identified on the surfaces of callus cells of Ruta graveolens, Ruta pinnata, Daucus carota, and Pastinaca sativa in the concentration range of 0.055 – 1.1 μg total/g fresh weight. In some cases these surface deposits amounted to a substantial percentage of the total, with the highest (67%) in Daucus, but they were not always proportional to the total concentrations in the cells. Variation in the ratios of concentrations of the individual coumarins indicated selective extrusion. An unresolved mixture of isopimpinellin and bergapten, with the former predominating in the proportion of ca. 7:1, was extruded in the highest concentrations on brown callus. Shake cultures produced up to two orders of magnitude more furanocoumarins than callus cells and extrusion was accelerated, but the concentrations of particular exported furanocoumarins varied, again pointing to selective extrusion.

New Location

To help improve cow traffic in automated milking systems, we examined whether heifers could be trained to approach a feeder in response to a tone emanating from their collars. Eighteen dairy heifers were used in four experiments. Ten heifers were trained by operant conditioning. Eight of these heifers approached the feeder more frequently and with a shorter mean latency following the tone than in the control periods (P < 0.05). Four of the heifers were tested in a new location but none of the heifers approached the feeder following the tone. A further eight heifers were trained by classical conditioning. When tethered close to the feeder during training, no animals learned to approach the feeder in response to the tone. When four heifers were trained while loose in the pen and had a second tone that predicted an aversive treatment, the animals approached the feeder more often after the positive tone (P < 0.05). Operant conditioning can be used to train heifers to approach a feeder in response to an auditory signal. Classical conditioning procedures are less effective and the optimal training procedures need to be defined before implementation in automated milking systems.

In Vitro Rumen Fermentation

The aim of this research is to compare alternative inoculant source for in vitro rumen fermentation. In the first experiment, inoculant from fistulated cattle kept in LIPI and IPB (Fis1 and Fis2) and inoculant from Bogor municipality abattoir and IPB abattoir (Abo1 and Abo2) were tested for their pH, total bacterial count, and protozoal number using a complete block design with four replications. In the second experiment, the effect of the inoculant sources was tested on cornmeal (F1), soybean oil meal (F2), Napier grass (F3), and dairy cattle complete ration (F4) fermentability and digestibility including pH, VFA, NH3, IVDMD and IVOMD parameters. The results showed an unsignificant different protozoal number among inoculant sources. The pH of Fis2 rumen liquor was significantly lower (p<0.05) than others. The bacterial population was significantly higher (p<0.05) in Fis2 and Abo2 than Abo1, and Fis1. The inoculant pH after feed fermentability was not influenced by feed type but inoculant source with Fis1 was significantly higher (p<0.05) than Fis2, Abo2, and Abo1. The ammonia, VFA concentration, IVDMD, and IVOMD were influenced by interaction between inoculant sources and feed types. Although inoculant from cattle close to the laboratory (Fis2 and Abo2) were better in term of higher bacterial population, higher fermentability and digestibility for most type of feeds but other sources can be used in vitro study without differences in average fermentability and digestibility results.

<p>Phenomenon of Merapi Mountain that the most active Strato mountain in Indonesia was interest to learn. There many explosion were threat of danger, not only human but include with property. Fact, there many people in the dangerous Merapi area were not escape from the area when Merapi showed raising activity. The research conduct to determine environment factors were motivated people on Merapi slope not to flee. The method used by descriptive analysis, data were taken with survey, the respondent of survey taken by purposive random sampling method. The result showed that: 1) Effort to defend economics asset as the main source of family income, dairy cattle<br />in the case, because of there’s no good evacuation stable for cattle, 2) Experiences of the past, there were none human killed or property loss in their village and 3) People’s believe for generation that his area was not in dangerous because it stand in front of the mountain; were motivated people on Merapi slope not to flee.</p><p>Key words : Environment, Merapi, flee, animal</p>

The proportion of MCFA in milk fat was lowest for Holstein, highest for Jersey, and intermediate for Brown Swiss cows. Proportions of SCFA (C4:0 to C8:0) and LCFA (> 18 C) did not differ among breeds. Differences in fatty acid composition among breeds were small, but could contribute to differences in manufacturing properties of milk fat. Key words: Holstein, Jersey, Brown Swiss, milk fatty acids
