    Notes: [Auszug] IT is generally accepted that when liquid milk is fed io young calves it by-passes the rumen and reticu-lum, by means of the cesopbageal groove1, and enters directly into the abomasum. This permits the food to undergo monogastric digestion. The recent trend towards the early weaning of calves by a ...

    OBSERVATIONS ON THE UTILIZATION OF GRASS GRAZED BY YOUNG BEEF CATTLE WITH AND WITHOUT BARLEY SUPPLEMENTATION (1966)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 21 (1966), S. 0

    Notes: A field trial was carried out in which 3 groups of cattle were grazed on a paddock system with and without supplementary barley. The cattle were 6 months old when turned out to grass and were each fed 4 lb/day of barley for one week to prevent any adverse effect from an abrupt change of diet. The trial began on 14 May and continued until 8 October. The mean liveweight gain obtained on the unsupplemented grass was only 0·97 lb/day up to 20 August and owing to the poor growth of the animals a supplement of 4 lb barley/head/day was then introduced. The daily liveweight gain for the remainder of the trial was 1·94 lb. When a supplement of 4 lb barley was provided throughout the trial the mean daily liveweight gain was 1·61 lb. When barley was fed ad lib. intake averaged 12·3 lb/head/day throughout the trial and the mean daily gain was 2·45 lb.Indoor digestibility and nitrogen retention trials were carried out. The starch equivalents of diets on the three treatments were 63·7, 68·3 and 69·5, respectively. The respective mean daily intakes of dry matter were 11·2, 11·9 and 11·8 lb, and the mean daily retentions of N were 35·0, 35·8 and 33·6g. These results indicate that although the grass was of good nutritive value the poor performance of the animals on grass alone was mainly due to their inability to graze sufficient grass.

    THE UTILIZATION OF GRASS FED INDOORS TO YOUNG BEEF CATTLE, WITH OR WITHOUT SUPPLEMENTARY BARLEY (1967)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 22 (1967), S. 0

    Notes: An experiment was carried out in which grass was cut and fed indoors, with or without supplementary barley. Seven animals were allocated to each of the following treatments: (1) grass ad lib. without supplementary barley; (2) grass ad lib. with supplementary barley at the rate of 0.5 lb/100 lb bodyweight; (3) grass ad lib. with supplementary barley at the rate of 1 lb/100 lb bodyweight. Supplementary barley increased total dry-matter intake and improved daily liveweight gain and food conversion rate. The mean daily liveweight gains for the 17-week experimental period were 1.60, 1.91 and 2.20 lb and the corresponding feed dry-matter conversion ratios were 6.18, 5.67 and 5.55 for Treatments 1, 2 and 3, respectively.The dry-matter digestibility of the diets was slightly higher when the grass was supplemented with barley than when grass alone was given. Although barley depressed the digestibility of protein, the absolute and the proportionate retention of nitrogen was increased. This was particularly marked on Treatment 3, presumably because of the higher net energy value of the diet containing the greater amount of barley. The N-retention data corresponded to the rates of liveweight gain obtained.

    Radiation-induced crosslinking and cyclization in 1,2-polybutadiene (1974)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 12 (1974), S. 2255-2271 
    Details

    Notes: In order to get information on the radiolytic changes in 1,2-polybutadiene (1,2-PB) the sol and gel fractions, the conversion of double bonds, the structure and concentration of radicals, the formation of dienes and the formation of gaseous products were measured. In addition, the dose rate dependence and temperature dependence for the conversion of double bonds were determined. G values for double bond conversion depend on molecular weight and range from 20 to 200. G values for crosslinking are about 10. A mechanism for the double bond conversion is proposed which involves initiation by a transformation of the primary radical ion in the vinyl group into a carbonium ion and a radical. This is supported by ESR measurement. Reaction of the carbonium ion with a vinyl group in the same chain gives rise to cyclization, whereas reaction with a vinyl group in a neighboring chain results in crosslinking. A comparison of the G values for conversion of double bonds with the G values for crosslinking shows that the formation of cyclic rings exceeds the formation of crosslinks by a factor of about 10. The corresponding values in 1,4-cis- and 1,4-trans-polybutadiene are much smaller [G(cl) ≃ 2; G(db) ≃ 7]. The pendent vinyl groups in 1,2-polybutadiene therefore are more reactive than the vinylidene groups in 1,4-polybutadienes.

    Description / Table of Contents: Radiolysis of polypropylene sulfide with thiol and thioether endgroups was investigated. The results of change in average molecular weight with radiation dose show that statistical main chain scission takes place (Gsc = 0.4-0.7). The following radicals could be identified by ESR-spectroscopy: A mechanism is proposed, which correlates the radical formation with chain scission. It can be shown that predominantly C—C bond scission and not C—S bond scission takes place.
    Notes: Die Radiolyse von Polypropylensulfid mit Mercapto- und Thioätherendgruppen wurde untersucht. Die Ergebnisse der Molekulargewichtsveränderung mit der Dosis ergeben, daß statistischer Kettenbruch auftritt (GBruch = 0,4-0,7). Folgende Radikale konnten ESR-spektroskopisch identifiziert werden: Es wird ein Mechanismus aufgezeigt, der die Radikalbildung mit dem Kettenbruch in Zusammenhang bringt. Hieraus geht hervor, daßB bevorzugt Spaltung von C—C und nicht von C—S-Bindungen stattfindet.
