    GRASSLAND RECORDING. II (1964)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 19 (1964), S. 0

    Notizen: 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.

    AN INVESTIGATION INTO THE MERITS OF INTENSIVE ROTATIONAL GRAZING (1964)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 19 (1964), S. 0

    Notizen: An investigation into the merits of intensive rotational grazing or paddock grazing was started in 1960. The experiment covered 40 acres, half of which was divided into 20 single-acre paddocks and the other half into 2 fields of 9 and 11 acres, respectively. Two groups of carefully paired cows were used to measure the output of milk per acre. Surplus grass was used for drystock and for conservation. The final output was expressed in terms of U.S.E. per acre, which was computed from the records of milk production, livestock maintenance and fattening and grass cut for conservation. The following conclusions seem reasonable: (a) Where the stocking rate is the same under both systems and the grass supply exceeds the animals' appetites, very little difference in terms of milk yield per acre will be found between intensive rotational grazing and lax rotational grazing over the grazing season; (b) Where, because of heavier stocking or a poorer growth of grass, the animals' appetites begin to exceed the grass supply, the intensive system of rotational grazing will be able to carry the stock for a longer period and consequently will give a greater output of milk per acre; (c) Intensive rotational grazing gives greater opportunity for taking off surplus grass for dryslock or for conservation.

    A STUDY OF SOME FACTORS CAUSING MAT FORMATION OF RESEEDED HILL PASTURE SWARDS (1964)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 19 (1964), S. 0 
    Details
    ISSN: 1365-2494

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: A comparison of non-mat and mat ecotypes of three reseeded hill swards showed that mat pasture soil was characterized by relatively high C/N ratios, low available nutrient status, low burrowing earthworm biomass, and low soil microbial activity (determined as CO2 evolution).A replicated trial was laid out on a uniform mat area of one of these swards (Ciderhouse Hill) and lime and fertilizer treatments were applied in two successive seasons. Lime treatment reduced mat weight, increased the proportion of ‘sown’ grasses in the sward and stimulated soil microbial activity, Initially, burrowing earthworm biomass was inhibited by lime; but, after an interval of four years, a positive response was noted at the lower treatment level. Sodium nitrate interacted with lime to increase soil microbial activity. Soil cellulolytic activity was increased by nitrate and phosphate treatments. The level of soil moisture in the field at the time of soil sampling appeared to influence soil microbial activity measured under standard conditions in the laboratory: high rainfall tended to reduce microbial activity. The significance of these findings and the infiuence of nutritional and climatic factors on sward reversion and mat formation are discussed.

    STUDIES ON SHEEP GRAZING IN THE NORTHERN PENNINES (1964)

    Notizen: The sheep grazing intensity and herbage intake on 3 high-level grasslands above 2250 ft were investigated. The seasonal intake, which varied from 450 to 700 lb dry matter/acre, was obtained by the yield-difference method, using cages moved monthly.

    THE EFFECT OF LEVEL OF NITROGEN AND CUTTING TREATMENT ON LEAF AREA IN SWARDS OF S48 TIMOTHY (PHLEUM PRATENSE, L.) AND S215 MEADOW FESCUE (FESTUCA PRATENSIS, L.) (1964)

    Notizen: Leaf-area index was increased by nitrogen application, but the increase was restricted by frequent cutting, which limited the incidence of high leaf-area indices. Timothy swards had higher leaf-area indices than meadow-fescue swards between April and mid-July, the period in which maximum values were recorded. N significantly increased the leaf area per g of leaf (leaf-area/leaf-weight ratio) at the beginning of the experiment, but not thereafter; the effect of cutting on this ratio varied with the date of cutting. Leaf areas per g of leaf were similar for the 2 species at the beginning and end of the experiment, but in mid-summer values for timothy increased whilst those for meadow fescue decreased. The relationship between leaf-area index and yield of dry matter is discussed.

    STUDIES ON THE HEIGHT/WEIGHT RELATIONSHIP IN DESERT RANGE GRASSES OF INDIA (1964)

    Notizen: Studies on height/weight relationship of the key grass species of Western Rajasthan ranges, India, were undertaken so as to form concepts which will guide the assessnient of the extent of their utilization by the livestock. Regression studies of the data obtained indicated that the relationship between the percentage of height clipped and the percentage of weight removed is quadratic. A graph has been drawn for each of the 5 species to relate the percentage of height removed with the percentage of weight utilized. The studies have shown that the weight distribution in respect of height is different in different species.
