SUMMARY1. The importance of uniform production of herbage for crop-drying is emphasized.2. A replicated experiment is described which compared four crops, two annuals and two leys under four manurial treatments which included a control and three applications of fertilizer (3½ cwt. ‘nitrochalk’) distributed during the season in three ways.3. Vetches yielded 2500–3000 lb. dry matter per acre of 28–30% crude-protein content in two cuts.Barley yielded 2500–3000 lb. dry matter per acre of 18–21% crude protein in five to six cuts.Leys yielded 4000–5000 lb. dry matter per acre of 15–18% crude protein in four cuts in their first year, and 5000–6000 lb. dry matter per acre of 15–18% crude protein in five cuts in their second year.

Two Stages

1. Three contrasting varieties of spring oats were grown at six centres in England and Wales for three seasons, at two levels of manuring. They were harvested at two stages of ripeness, and both straw and grain were analysed for all treatments.2. Varietal differences in composition between samples of straw grown under similar conditions and harvested at comparable stages of ripeness were negligible. In this respect there was no relationship between quality of straw and that of grain.3. Differences in composition attributable to environment were very large. Crude protein content ranged from 1·9 to 7·6%, and crops grown under cool and wet conditions always yielded a better quality straw than those grown under the warmer and drier conditions in the south of England.4. The chemical composition of oat straw changed very little between the early ‘binder-ripe’ stage and the fully ripe ‘combine’ stage, although physically it tended to become more brittle and less attractive in appearance. The grain also showed little change in composition between the two times of harvesting.5. A spring dressing of 2 cwt. per acre of nitrochalk increased the protein content of the straw very considerably, but the response varied widely with conditions. The average increase at all centres over three years was 20%.6. Under cool and moist conditions the composition of oat straw was comparable with that of meadow hay.

The objective of this study was to evaluate the morphogenetic traits and chemical composition of Tanzania grass using a fixed rest period or according to light interception at 95%. The treatments consisted of evaluations of two Tanzania-grass pasture-management strategies: (1) LI95 - animals entered the paddocks when the pasture reached 95% of light interception (LI), with three days of paddock occupation; and (2) FR - the pasture was managed with a defoliation interval (DI) of 30 days, and three days of paddock occupation. The experimental area consisted of 4 ha, with 22 paddocks per treatments. Ten recently-calved cows were used per treatment in year 1, and eight cows were used per treatment in year 2. Sward height, forage mass, and morphological components and their chemical composition were evaluated. The management strategies used on the Tanzania grass pasture did not affect pasture mass or height in the pre- and post-grazing conditions, or the proportion of stems. However, the proportion of leaves was greater in the paddocks with 95% light interception. The crude protein content was higher in the paddocks with 95% light interception; the other nutrients were not affected. In conclusion, management adopting 95% light interception does not influence morphogenetic traits. Nevertheless, it promotes an increase in the crude protein content of grasses.

The study examined the nutrient composition of twelve plants species used as feed in Bauchi metropolis. They were collected during the month of April which is considered the peak of the dry season. The plants were divided into four groups: Trees, grasses, leguminous herbs, and non-leguminous herbs. The result showed that the crude protein content ranged from 13.61% for the leguminous herbs to 17.9% for the non-leguminous herbs. The result also showed that the plants have light nitrogen free extract and mineral requirement of rabbits with little supplementation especially during the dry season when there is acute shortage of feeds.

Ladino clover grown alone and in mixture with timothy and smooth bromegrass was cut two, four and six times per season to a height of [Formula: see text] and 3 inches. Forage harvested in 1955 and 1956 from a seeding made in 1954 at the Experimental Farm, Lennoxville, Quebec, was chemically analysed.Ladino clover contained more K but less N-free extract and Ca when grown alone than when associated with a grass. Bromegrass had a higher content of crude protein, ash, P and K, and a lower content of N-free extract than timothy.Height of cutting failed to modify the chemical composition of the grasses. In the clover, close cutting reduced the fat and K contents and increased the ash content.The crude protein content increased and the crude fibre and N-free extract contents decreased in both forage fractions with increasing cutting frequencies. Fat was highest in the clover cut four times and in the grasses cut four and six times. The ash content in the clover was not significantly altered by cutting frequency but tended to decrease with increasing maturity in the grasses. The Ca content was lowest in the clover cut six times and in the grasses cut twice. In both forage fractions, the P and K contents were higher with either four or six cuttings than with two cuttings.

Forage Crops

The management of non-leguminous annual forage crops can affect dry matter (D.M.) yields, chemical composition, and nutritive (feeding) values largely because of the stage of maturity at which the crop is harvested. After studies for selecting high-yield forage oat varieties for a highaltitude tropical climate (Haile, 1976), it was considered necessary to look into the management of forage oats so that the time of harvesting for maximum forage and crude protein yield could be established.

<p>The digestibility of the lichen Stereocaulon paschale is studied in a digestibility trial with two reindeer calves. The lichen is collected near Kautokeino in Northern Norway. Chemical composition of the lichen is shown in Table 1. Compared with Cladonia-species the content of crude protein and ash is higher in Stereocanlon paschale The content of Ca, P and Mg in the two species is of the same magnitude, while the content of Na and CI is ten times higher in Cladonia alpestris. The estimated digestibility is shown in Table 2. The dry matter digestibility is calculated to 46, 4%, which is very low compared to Cladonia-species. The higher crude protein content in Stereocaulon paschale has resulted in a positive apparent digestibility of protein.</p><p>Tinaj&aring;k&aring;l&aring;n (Stereocanlon paschale) sulavuus porolla.</p><p>Abstract in Finnish / Yhteenveto: Tinaj&aring;k&aring;l&aring;n sulavuutta on tutkittu sulavuuskokeissa kahdella poronvasalla.

The objective of this study was to evaluate the chemical composition and protein and carbohydrate fractions in three forage species (Andropogon gayanus Kunth, Cenchrus ciliares L. and Panicum maximun x Panicum infestum) at four cutting ages: 21, 35, 49 and 63 days. Experiments were carried out at the Federal Institute of Education Science and Technology of Rio Grande do Norte - IFRN, located in the municipality of Apodi- RN, Potiguar West Meso-region. Materials collected in the field were analyzed in the Laboratory of Animal Nutrition (LANA), Federal Rural Semiarid University (UFERSA), Campus Mossoró, RN. Samples were processed, phenated, and analyzed. The analysis conducted included fractionation of nitrogen compounds and carbohydrates and chemical composition (dry matter, mineral matter, crude protein, lipids and fibers) was determined. The forages evaluated showed decreasing crude protein content with increasing cutting age, ranging between 14.9 and 6.2%. Andropogon grass showed the highest crude protein content. The fiber content increased with age. Fiber consisted of 62.4%–70.0% NDF and 30.07%–33.03% ADF. Highest fiber content was recorded for Massai grass, in which case, these two component species showed the highest fractions of intermediate degradation protein (B2), while Andropogon and Buffel Capins showed higher fractions of non-fibrous carbohydrates (A and B1). An increase in the concentration of cell-wall material in the detriment of the cellular content with increasing plant age was observed in the fodder studied. We also observed an increase in the indigestible fraction (C) of proteins and carbohydrates in the species studied.
