    THE OUTPUT OF SWARDS ON COMMERCIAL FARMS IN RELATION TO FERTILIZER AND OTHER MANAGEMENT FACTORS (1965)

    Notes: Survey data collected during a grassland-recording investigation showed a strong positive correlation between nitrogen input and the output of utilized starch equivalent per acre. At the levels of output covered, sward type was not very important in relation to total yield. Herbage species were important for other reasons and the choice of seeds mixtures should be determined by factors such as earliness and lateness of growth and resistance to disease and drought. The survey showed that well-managed ley and permanent pasture are both capable of producing at a high level. A disturbing feature of the results was the low production of most spring resowings, primarily as a result of poor management. Although the records were obtained from an above-average group of farms, the results have general application. Potential responses to fertilizers may be even greater on less intensive farms, especially with regard to phosphate and potash. However, the level of production of a field will always depend finally on the level of management exercised by the farmer himself.

    The Fine Structure of Lankesterella garnhami (1962)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 9 (1962), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Thin sections of Lankesterella garnhami were examined by electron microscope and the morphology of trophozoites and sporozoites is described. The envelope of the organism consists of a double membrane, which (in the presumed sporozoite) is broken at one point posteriorly by the microphyle. The anterior end possesses characteristic organelles, which include an open apical ring leading to a collar or conoid and to 30 peripheral fibrils, a paired organelle, and numerous “lankesterellonemes.” Typical mitochondria and a Golgi apparatus are found in the cytoplasm and a nucleus of heterogeneous nature.

    Lipid and Sterol Content of Some Protozoa (1961)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 8 (1961), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Total lipids of several protozoa were determined and found higher than in most other microorganisms. The lipid content in a phytoflagellate, Ochromonas malhamensis, could be increased by excess nicotinic acid or deficiency in nitrogen supply. Cell multiplication and lipid synthesis were unaffected by inhibitors of vitamin synthesis such as penicillamine, pan-toyltaurine, or pyridine-3-sulfonic acid, up to 100 mg%. The phytoflagellates, O. danica, O. malhamensis, Euglena gracilis, and the photosynthetic bacterium Chlorobium limkola contained large quantities of non-saponifiable lipids: ergesterol was identified as a major component of this lipid fraction. Sterols were not found in the bacteria, Streptococcus faecalis, Rhodopseudomonas palustris; the algae. Cyanidium calidarnm. Anacystis nidulans, and Porphyridium cruentum; and the protozoan Tetrahymena pyriformis.

    The Host-Restriction of Haemoproteus sp. indet. of the Wood-Pigeon Columba p. palumbus (1966)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 13 (1966), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Earlier experiments suggested that the species of Haemoproteus which infects English wood-pigeons (Columba p. palumbus) and is transmitted by the hippoboscid dipteran fly Ornithomya avicularia, was unable to infect Columba livia domestica, a host of H. columbae. This has now been confirmed by the injection of sporozoites into two pairs of pigeons, one of each species; in both experiments the C. palubus developed parasitemia while the C. livia did not. It has also been shown that this species of Haemoproteus can complete sporogony in a small proportion (2/73) of Pseudolynchla canariensis, the vector of H. columbae.

    Notes: The traditional method of calculating field output by the utilized-starch-equivalent (U.S.E.) system is compared with a recommended simpler and quicker method. The concept of calculating a U.S.E. factor is introduced and forms the basis for the new method. A monthly U.S.E. factor is used, in conjunction with monthly cow-day (CD.) records to calculate U.S.E. Savings of at least 50% may be expected. Agreement between the two methods is very close and the more seasonal nature of the calculation for sheep and non-milking cattle under the new method may be preferable.

    A COMPARISON OF COCKSFOOT- AND TALL FESCUE-DOMINANT SWARDS FOR OUT-OF-SEASON PRODUCTION (1965)

    Notes: Swards based on a mixture of SI 70 tall fescue and S215 meadow fescue were very early in spring, gave high yields for conservation in mid-season and, rested from mid-August, gave good grazing in November-December. Under this treatment, the tall fescue assumed dominance, and the swards were persistent and remained productive. The digestibility of the tall fescue swards was always higher than that of swards based on cocksfoot with which they were compared. During spring and autumn the former sward was better grazed by stock, but the position was reversed in mid-summer. Cattle grazing tall-fescue-dominant swards made better liveweight gains than those grazing cocksfoot swards during November-December.

    Notes: Two systems of recording the output of grass fields—by cow-days (CD.) and by utilized starch equivalent (U.S.E.)—were compared with field measurements of the dry matter and digestible matter consumed over a period of two years.On one farm, each recording system was positively correlated with both the amount of dry matter and the amount of digestible matter consumed from individual fields by grazing cows. Consequently, the two systems reflected equally well the total quantity of utilized herbage and its quality. This was explained by a highly significant correlation between the two recording systems. The same correlation between the two recording systems existed on 20 other farms.It was concluded that the C.D. and the U.S.E. systems gave equally reliable results when assessing field output within dairy farms. Because C.D. can be determined with greater ease they should be used instead of the U.S.E. system. However, the U.S.E. system is still advocated for assessing grass utilization for animal production on a farm basis, since it indicates the level of efficiency which farmers achieve in using their grass.
