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.

Abstract Alternative forms of protein are an important focus in nutrition. This study sought to compare the effects of pelleting and extrusion on nutrient composition and protein quality measurements of Canadian pulses. Pulses used for the study included: 2 pea variety (Amarillo and dunn), lentils, chickpeas, and faba bean. Ingredients were ground through a 10/64” or a 2/64” screen to create a coarse and fine ground product, respectively. Both coarse and fine ground ingredients were pelleted at 60–65, 70–75, and 80–85 C0. Fine ground ingredients were extruded at three different temperatures (110, 130, 150 C0) and two moisture levels (18 and 22%). Samples were collected for all runs at the beginning, middle, and end of each run for both pelleted and extruded samples. Samples were analyzed for proximate analysis, amino acids including lysinoalanine, total and damaged starch, and total dietary fibre (including insoluble and soluble). Data were analyzed using a mixed model via proc glimmix in SAS, where ingredient, process, grind, temperature, and extrusion moisture were treated as fixed effects with different interactions selected based on model investigated. Crude protein content of whole pulses was highest in faba bean and lowest in the Amarillo pea, with faba bean protein content significantly higher than all other pulses, and lentil protein content significantly higher than Amarillo peas (P < 0.05). All pelleting temperatures, nested within grind, significantly increased crude protein content of all pulses compared to whole pulses (P < 0.05). All extrusion moistures significantly increased crude protein content of all pulses compared to whole pulses (P < 0.05) and moisture/temperature interactions were significantly higher for all pulses compared to whole pulses (P < 0.05). Amino acid comparisons produced similar significant results. This suggests that pelleting and extrusion processing can have a positive impact on protein content of pulses and protein quality measurements in pulses.

The experiment with natural meadow of Agrostis capillaris - Festuca fallax type in Rhodope Mountains (Smolyan region, Southern Bulgaria) shows that according to fertilization variants there is a clear tendency towards earlier start of active vegetation and its next phenophases. Most and almost equal amounts of dry biomass (4.38 and 4.31 t.ha-1) were reported in fertilization with N160P80K80 and N160P80, which exceeded the unfertilized control by 128.12 and 124.48%, respectively. Compared with unfertilized variant, the crude protein content increased in all fertilizing variants, as in complete mineral fertilization with N80-160 accumulates the crudest protein - respectively 314 g.kg-1 and 318 g.kg-1. As regards to other studying chemical indicators of the forage (crude fiber, crude fat, crude ash and nitrogen-free extract substances) the mineral fertilization also had an expressed positive effect.

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.

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.

The objective of this study was to evaluate the effects of the application of different water depths and nitrogen and potassium doses in the quality of Tanzania grass, in the southern of the state of Tocantins. The experiment was conducted on strips of traditional sprinklers, and used, as treatments, a mixture of fertilizer combinations of N and K2O always in the ratio of 1 N:0.8 K2O. This study determined throughout the experiment: plant height (PH), the crude protein (CP) and neutral detergent fiber (NDF). The highest plant height obtained was 132.4 cm, with a fertilizer dose of 691.71 kg ha-1 in the proportion of N:0.8 K2O, in other words, 384.28 kg ha-1 of N and 307.43 kg ha-1 of K2O, and water depth of 80% of the ETc. The highest crude protein content was 12.2%, with the fertilizer dose application of 700 kg ha-1 yr-1 in the proportion of 1 N to 0.8 of K2O, in other words, 388.89 kg ha-1 of N and 311.11 kg ha-1 of K2O and absence of irrigation. The lowest level of neutral detergent fiber was 60.7% with the application of the smallest dose of fertilizer and highest water depth. It was concluded in this study that there was an increase in plant height by increasing the fertilizer dose and water depth. The crude protein content increased 5.4% in the dry season, by increasing the fertilizer dose and water depth. In the dry season, there was an increase of NDF content by 4.5% by increasing the application of fertilizer and water depth.

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.

Content of crude protein and cell wall constituents in leaves and stems of alfalfa (Medicago sativa L.) cv K-22 with advancing maturity was investigated. Sampling was done in 7-day intervals in second cut. During growth and development, crude protein content decreased in leaves and stems, from 332,6 to 328,8 gkg-1DM and from 138,6 to 122,0 gkg-1DM, respectively. From first to third development stage, content of ADF in leaves and stems increased, from 352,0 to 476,7 gkg-1DM and from 592,8 to 867,1 gkg-1DM, respectively. Highest contents of ADF and hemicellulose was stated in plant parts in third development stage, in leaves 187,4 and 289,3 gkg-1DM, and in stems 499,4 and 367,7 gkg-1DM. The highest changes of lignin contents are in stems, while content of lignin in leaves increased from 42,0 to 49,0 gkg-1DM.
