    Notes: A review of American literature indicates that barn drying of hay and silage making are both greatly superior to the field curing of hay in preserving nutrients. This is true of total dry matter, crude protein, ether extract and ash; crude-fibre losses are greater in silage making. Energy losses run parallel with dry matter. Bam drying of hay with heat preserves a rather greater proportion of nutrients than does silage making.Chemical composition and digestibility are mostly a function of stage of maturity of the crop at the time of cutting. Actual carbohydrate (energy) losses are greater than protein losses in all methods. The influence of method of conservation is unimportant if conservation is properly carried out, but considerable deterioration can result from bad application. Field-cured hay usually suffers most in this respect, due to weather damage.The conservation processes reviewed have no influence per se on feeding value where each is applied under ideal conditions. Differences found in practice are usually linked to the stage of maturity or to weather damage, which explains the usually superior feeding value of silage and barn-dried hay over field-cured hay.When the efficiency of each method is compared by determining the quantity of milk produced from equal areas of forage, conserved in the three different ways, barn-dried hay is somewhat superior to silage, but both are greatly superior to field-cured hay.

    Notes: The effect of temperature on silage quality was investigated in a series of trials over a period of three years.The results indicated that when conditions in the silage were favourable for the formation of lactic acid, either through treatment or because of the herbage itself, low temperatures in the mass had no adverse effect on silage quality.Some results suggest that, with chopped or lacerated silage, low maximum temperatures are associated with better quality silage. The results, however, were not entirely consistent.There appeared to be little or no advantage in allowing unchopped silage to heat to 100°F.

    Notes: An experiment was started in 1957 that compared the production from dairy cows on daily strip-folding with that from a system of rotational grazing where the cows were given a fresh allocation of pasture about once or twice a week. Management was so arranged that equal areas of pasture were grazed off by the same number of cows in a similar period of time. The experiment was carried out at two rates of stocking, one about 20% greater than the other, the lower rate considered to be equivalent to good close folding practice and the higher rate therefore somewhat restrictive. No supplementary food was given during the grazing season.At the high rate of stocking, rotational grazing gave an average milk yield of 40 lb./cow/day whilst daily strip-folding yielded 38 lb./cow/day. At the low rate of stocking production was 42 lb./cow/day for both methods.At the high rate milk yield/acre from the rotational grazing was 1007 and from the strip-folding 977 gals. At the low rate comparable results were 881 and 874 gals.There was no general trend in yield per cow or per acre in favour of either the rotational grazing or daily strip-folding systems of management. Increasing cow days/acre by 21% decreased yield/cow/day by 7% but significantly increased milk yield/acre, by 13%.

    Notes: In an attempt to measure the influence of leys on the yield of barley, as a means of measuring soil fertility, details of the yields of barley, fertilizer usage and rotations were collected from a number of Hampshire farms and compared with the average results obtained from the ley fertility experiment at Bridget's Experimental Husbandry farm. In the arable rotation experiment increasing the nitrogen level from 37 to 74 units, increased the barley yield from 20·2 cwt. to 24·3 cwt.Farm number 1 used 43 units of nitrogen compared with 61 units of nitrogen on farm 2. The yield rose from 18·7 to 25·4 cwt.Following 3 years grazed ley at Bridget's and increasing the nitrogen level from 37 to 74 units raised the yield from 25·5 cwt. to 29 cwt.Farms 4 and 5 used 47 units of nitrogen compared with 74 units of nitrogen on farms 7, 8 and 9. The yield rose from 24·7 cwt. to 30 cwt.Farms 6 and 10 obtained 29·1 and 28·7 cwt. from only 49 units of nitrogen and 26 units of nitrogen respectively, by the use of some lucerne leys on farm 6, and by only taking one grain crop on farm 10.A three year ley is therefore probably worth 15 cwt. of increased barley yield in the 3 succeeding crops of grain, when using not less than 26 units of nitrogen. An additional 5 cwt. of barley can be obtained annually by the use of 37 units of nitrogen.A sharp fall in yield in 1956 and 1957 on farm 10 to 217 cwt. may have been due to a reduction in the use of nitrogen, or other causes.Farm number 3, without livestock, obtained 28·1 cwt. when using 86 units of nitrogen. Was this due to the use of a 2 year ley and fallow crop in a six year rotation, or the use of additional nitrogen: farm 8, at the same level of nitrogen, stocking and use of clover, has only gained 2·3 cwt. per acre.

    THE PRODUCTION OF EARLY SPRING GRASS (1960)

    Notes: Spring nitrogen significantly increased the yields of early spring grass. The response per lb. of nitrogen applied in the early spring ranged from 9 to 28 lb. of dry matter, depending upon the weather. Autumn nitrogen significantly increased herbage yields during the autumn. The increase per lb. of nitrogen ranged from 12 to 22 lb. of dry matter.Autumn nitrogen caused significant increases in the yield of early spring grass in 1956, but these increases were very small and not of practical importance.The effects of autumn grazing on spring yields were not consistent and were small when compared with the effects of spring nitrogen. Both autumn grazing and autumn nitrogen tended to reduce the percentage of soluble carbohydrates in the stubble and roots of grasses in November.

    Notes: Three experiments designed to test the effect of height of cutting of lucerne on subsequent yield are described and the results discussed. Extremely low cutting, at ground level, can cause the death of individual lucerne plants, but if such extreme cutting is avoided there is no evidence to show any advantage in leaving a long stubble. In fact, in a sward, the lower the cutting the greater is the yield to be expected.

    Notes: Five early, three mid-season and two late varieties of lucerne were grown in drills in a replicated plot experiment at the Hannah Dairy Research Institute in south-west Scotland in the period 1956–59, inclusive. The lucerne was cut three times each year after the year of establishment (1956).Average yields were 10,200 lb. of dry matter and 1970 lb. of crude protein per acre in the first harvest year, but declined rapidly to 6290 lb. of dry matter and 1190 lb. of crude protein per acre in the third year. On average, the early types of lucerne gave the highest yields of dry matter and crude protein. Over the three harvest years of the experiment, Flandria was the highest yielding variety and New Zealand B the lowest. The distribution of dry-matter yields averaged over all varieties was 44, 29 and 27% for cuts 1, 2 and 3, respectively.The crude-protein content of the herbage from all the varieties was high, 63% of the values being greater than 19%. Grimm, a late variety, had the highest crude-protein content.With all varieties tiller density declined rapidly from the first to the second harvest year, but increased again at the third harvest year.11–34% of the total yield of dry matter in the second harvest year consisted of weed grasses, but this was reduced in the following year by spraying the plots with Dowpon, a selective herbicide.

    Notes: It has been observed that, where surface seeding has been attempted, disappointing results occur on some sites due to delays in sowing the seeds mixture after lime and fertilizer applications have been made.An experiment is described in which the time of application of nitrogen, in relation to the establishment and development of S24 and S23 perennial ryegrass seedlings in pots, was varied. The results of trials on this aspect of surface seeding, under conditions experienced in the north of Scotland, are also given.More efficient utilization of nitrogen was obtained when applications were delayed until the seedlings had developed sufficiently to utilize the applied nitrogen. This delay enhanced the establishment of sown grasses under conditions where natural species, capable of responding to applied nitrogen, were present.Where surface seeding is undertaken, consideration should be given to delaying the application of nitrogen until the sown seeds have brairded.

    Notes: In view of the implication of ley-farming in the increasing incidence of hypomagnesaemia, a preliminary study has been made of the blood serum calcium and magnesium levels in bullocks grazing leys consisting mainly of S24 ryegrass or S170 tall fescue, and old pastures. It was found that the serum magnesium was significantly higher while the animals were grazing the leys and that the tall fescue appeared to provide more magnesium than the ryegrass.
