AbstractRoselle—Hibiscus sabdariffa L. leaves at different stages of growth, calyces and seeds were analyzed for nutritional and anti-nutritional factors. All the treatments contained a good but varied proportion of carbohydrate in a range of 26.93–54.13%, crude protein from 5.7 to 27.06%, crude fat 1.16–13.09%, crude fibre 15.75–36.10%, energy 631.36–1065 kJ, ash 6.08–13.74% and moisture content 6.00–9.7%. The vitamins A, C and E were also found to be present in all the treatments in a different but substantial amount. The calcium, magnesium and iron contents in all the treatments were higher than the recommended daily allowance of 1250, 350, and 15 mg for adults, while the phosphorus and sodium values in all the treatments were below 1000 and 1500 mg RDA for adults. However, the Na + /K + for all the treatments were lower than 1. The values of anti-nutrients in the samples were small except post-flowering red which had high phytate content of 21.02%, although this can be easily reduced during processes like boiling and cooking. Thus, both cultivars of roselle contain high nutritional, elemental, and vitamins compositions and small content of anti-nutrients.

Rice bean, a lesser known pulse, has excellent nutritive value. The seed yield of the crop is higher as compared to other pulses of the Vigna family. In the present study thirty diverse rice bean genotypes were evaluated for nutritional and morpho-physiological characteristics for selecting overall superior genotypes. Variations were observed for crude protein (16.1–19.12%), carbohydrates (59.28–76.89%), ascorbic acid (0.19–0.80 mg/100 g), crude fibre (4.23-6.0%), limiting amino acids, namely tryptophan (0.85–2.42 g/16 g N) and methionine (0.52–0.67 g/16 g N), and ether extract (0.57–2.13%). Anti-nutritional factors, such as total phenolics, total tannins, condensed tannins, hydrolysable tannins and α-amylase inhibitor, also varied to a considerable extent. The cumulative grading of the genotypes based upon nutritional and morpho-physiological attributes revealed that the genotypes JCR-76, IC-137200, IC-140796 and IC-137189 were nutritionally superior genotypes for consumption.

The study was aimed at assessing the effects of two varieties of cashew (Anacardium occidentale) apple pulp as feedstuff for ruminants. Samples of the yellow and red varieties of cashew apple pulp were collected, processed and analysed for mineral, crude fiber fraction and pH. Results showed that sodium value in red variety was significantly higher (P<0.05) than that of the yellow variety. Potassium value in red variety was significantly higher (P<0.01) than that of the yellow variety. Values for calcium, magnesium, and phosphorus in the yellow variety were significantly higher (P<0.01) than those of the red variety. Values for cellulose, hemicelluloses and neutral detergent fibre in the red variety were significantly higher (P<0.01) than those of the yellow variety. Acid Detergent Lignin value for the yellow variety was significantly higher (P<0.01) than that of the red variety. Values for acid detergent fibre, crude protein, carbohydrate and pH were not significantly affected (P>0.05). Yellow cashew apple pulp from the results of this study is richer in minerals when compared to the red variety. Results from the crude fibre fraction suggest that the yellow cashew apple pulp variety may have a better digestibility when compared to the red variety. Although the values of the various parameters from the 2 varieties show that they are fit to be used as feeding stuff for ruminants, the yellow variety appears to be better on the general basis.

A study was carried out to determine the chemical composition of roselle seeds fermented at varying durations. One kg cleaned Roselle seeds were soaked in 3L of water for 8 hours. The soaked seeds were drained and fermented for 0, 24, 48, 72 and 96 hours as treatments. Samples of fermented roselle seeds at different duration of fermentations were analyzed for chemical composition including anti-nutritional factors. The results showed that there was significant (P<0.05) effect of fermentation duration on chemical composition and antinutritional factors of roselle seeds. Dry matter and crude protein content increased as fermentation duration increased from 0 to 96 hours. The highest dry matter (91.87%) and crude protein (35.05%) were obtained at 96 hours while crude fibre and ether extract decreased with increased fermentation duration. Crude fibre (6.55%) and ether extract (26.79%) were highest at 0 hours. Ash and nitrogen free extract content ranged from 5.41 – 5.78 % and 30.62 – 39.19 %, respectively. Anti-nutritional factor contents declined withincreased fermentation duration. The lowest values for saponin (2.02%), tannin (0.15%), phytic acid (5.44%) and trypsin inhibitor (8.93%) were obtained at 96 hours fermentation. It can be concluded that roselle seeds fermented for 96 hours enhanced nutrient availability and significantly reduced tannin, phytate, saponin and trypsin inhibitor anti-nutritional factors.

Purpose – The purpose of the study was to highlight the nutritive values and evaluate the safety level of beverages formulated from selected cereal filtrates in Nigeria. Design/methodology/approach – The cereals that were used for the formulation of the beverages are: 100 percent white maize, 100 percent yellow maize, 50:50; white: yellow maize, and 100 percent sorghum bicolour. All the cereals were purchased from Odo-Ogbe market in Ile-Ife, Nigeria. Findings – The results showed that the level of the minerals present in the cereal filtrates ranged from 39.1 to 43.6; 236 to 303; 362.4 to 462; 23.6 to 68.3; 26 to 41.5; 0.66 to 2.37; and 0.5 to 2.2 mg/100 g for sodium (Na), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), and manganese (Mn), respectively. Microbial load ranged from 2.0 to 3.0×10−3 cfug. Results of nutritional composition such as percentage moisture, protein, fat, carbohydrate, ash and crude fibre ranged from 91 to 93, 1.5 to 1.75, 0.03 to 0.040, 0.25 to 1, 1.48 to 1.70 and 3.33 to 5.31 g/100 g, respectively, while the energy value ranged between 66.60 and 75.56 kcal. The values obtained for vitamin C and thiamin ranged from 0.30 to 0.40 and 0.56 to 0.70 mg/100 g, respectively. Originality/value – The micronutrients in the formulated beverages met the minimum recommended daily allowance and also possessed antimicrobial activities. However, the results showed that the proximate composition was high in water and low in other nutrients but still compared favourably with previous findings. It was concluded that the beverage produced from selected fermented cereal filtrates waste was safe and rich in micronutrients.

The object of this series of investigations is to secure detailed information concerning the composition, digestibility and nutritive value of pasture grass in its different stages of growth. The results which were obtained in these respects by cutting the herbage of the experimental pasture plot at weekly and at fortnightly intervals have been described in previous communications. During the season of the present experiment, the trials have been carried a stage further by the adoption of a system of cutting at 3-weekly intervals. The main findings of the 1928 investigation are recorded below:(1) Chemical composition of 3-weekly pasture cuts: The adoption of a more lenient system of cutting at 3-weekly intervals led to a slight lowering of the percentage of crude protein in the grass and a slight raising of the percentages of crude fibre and N-free extractives. On the other hand, no corresponding effect was noted in respect of the ether extract, SiO2-free ash, lime and phosphate, the percentages of these constituents being very similar in the weekly and 3-weekly pasture samples obtained in 1928. The falling off of the percentage of crude protein in the 1928 3-weekly-mown herbage, as compared with the weekly and fortnightly-mown herbage of 1925 and 1927 respectively, was not wholly the consequence of the more lenient system of cutting, but was also due in part to the protein-depressing influence of the droughty periods which were experienced in the 1928 season.

A 3-yr study on the stages of growth of timothy (Phleum pratense L.) at harvest showed that the dry matter yields increased, in the spring growth, with advance in maturity. The highest annual yield was obtained, however, when the first cut was taken at the bloom stage. The percentage of crude protein, fat and ash decreased and that of crude fibre increased with the age of the plant. The Ca, P, K, Mg, Na, Zn and Cu contents declined with maturity while the elements Mn, Al, Fe and B did not vary significantly. The food reserves in the lower stem internodes were low at the vegetative stage in the spring (11.7% of DM), but raised rapidly up to the bloom stage (33.9%).

There are no published feed-energy standards for growing rabbits. Even nutritional factors that affect intake and digestibility, and consequently performance, are not well documented. Two experiments were carried out, as part of a programme to develop energy feeding standards for growing rabbits. Experiment 1 investigated the effect of physical and chemical characteristics on intake and digestibility of diets. Experiment 2 investigated the effects of level of feeding on digestibility of diets varying in energy density.A 3 x 2 factorial design was used in both experiments, with 20 Individually-fed weaned rabbits per treatment (initial weight approximately 800 g). Diets were pelleted (4 mm die diameter) and were of the same formulation in both experiments. Diets (LH, MB, HH) were formulated to contain different crude fibre levels (Table 1) by varying, the inclusion rates of grass hay - (LH, Low Hay, 273 g/kg; MB, Medium Hay, 556 g/kg and HH, High Hay, 831 g/kg). Diets were formulated to contain the same amounts of crude protein. In Experiment 1 the hay component In diets LHf, MHf and HHf was ground through a 1 mm screen whereas that in diets LHc, MHc and HHc was ground using a 6 mm screen. In Experiment 2, diets LHf, MHf and HHf were fed ad libitum or at 70% of ad libitum Intake.

1. Cuts of elephant grass (Pennisetum purpureum were made at 40–60 (trial 1), 30 (trial 2), 50 (trial 3) and 70 (trial 4) days of age. Determinations of voluntary intake, digestibility coefficients, rate of passage through the gut, time spent eating and ruminating, number of boluses, rate of chewing, production of volatile fatty acids (both total and individual) were determined using individually housed sheep.2. Digestibility coefficients of crude protein declined with the level of crude protein in the forage; digestion of the crude fibre fraction declined with advancing maturity. The digestibility of N.F.E. increased with increasing maturity resulting in similar values for T.D.N. among the four cuts. Digestibility of dry matter of the grass in trial 2 was significantly higher than that for the other three trials.

The experiment was conducted in the Department of Horticulture, Biswanath College of Agriculture, Assam Agricultural University, Biswanath Chariali in the period begning from November, 2016 till the end of 2018 with eight different banana cultivars grown in Assam i.e T1: Jahaji (AAA), T2: Amritsagar (AAA), T3: Chenichampa (AAB), T4: Malbhog (AAB), T5: Kachkal (ABB), T6: Manohar (ABB), T7: Bhimkal (BBB), T8: Wild banana (BB). Phytochemical assessment revealed the highest and lowest values of pH in the cultivars of balbisiana group and  acuminata group, respectively. The moisture content ranged from 80 to 90 percent; ash content, sucrose content, crude fibre and total carbohydrate content varied in all the cultivars. Sugar content in terms of glucose and fructose were highest in Chenichampa while the lowest glucose content was recorded in Amritsagar. Phosphorus content ranged from 51.98 mg/100g to 14.27 mg/100g while potassium content ranged from 786.40 mg/100g to 427.61 mg/100g. The male flower buds possessed crude protein, starch, anthocyanin, sugars, carbohydrates, proteins, important minerals like phosphorus, potassium, sodium, calcium, magnesium, zinc, iron and anti-nutrients like tannin, saponin and phenolic compounds, but their concentrations varied among the cultivars. Organoleptic taste revealed that the male flower buds of cultivars namely, Bhimkal (BB), Wild banana (BB), Malbhog (AAB) and Kachkal (ABB) were found to be tastiest for consumption as vegetable.
