Physicochemical and nutritional quality of five improved cultivars of desi and kabuli chickpeas and their products were studied. The kabuli chickpea had larger seed (26 g/100 seeds) than desi type (21 g/100 seeds). The hydration capacity per seed of desi (0.16 g) was lower than kabuli type (0.26 g). A positive correlation (r = 0.87) between seed weight and hydration capacity was observed. The mean cooking time of dry desi vs kabuli seed (124.5 vs 113.8 min) was reduced to 37.5 vs 32.8 min and to 28.8 vs 22.5 min when soaked overnight in water and in 0.5% solution of sodium bicarbonate respectively. The mean value of protein (25.4 vs 24.4%), fat (3.7 vs 5.1%), carbohydrate (47.4 vs 55%), crude fibre (11.2 vs 3.9%), ash (3.2 vs 2.8%) and caloric value (327 vs 365 kcal/100 g) were for desi vs kabuli chickpeas respectively. There was no difference in the essential amino acid contents and in chemical scores of desi (65) and kabuli (67) chickpeas. The order of limiting amino acid was methionine+cystine, threonine and valine in both types. The chickpeas products contained 8.9-21.1% protein (N x 6.25), 3.1-21.8% fat, 53.4-75.9% carbohydrate, 1.6-11.1% crude fibre, 1.2-5.9% ash, 226-360mg Ca, 126-315 mg P, 3.8-8.2 mg Fe, 1.8-5.4 mg Zn, 1.5-5.4 mg Mn, 0.6-1.1 mg Cu and 370-490 kcal per 100 g. All chickpea products provided 7-23%, 7-40% and 52-78% of the total calories from protein, fat and carbohydrates respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Pregelatinized maize-sweet potato mix, fortified with soybeans and groundnut flours, was evaluated for its acceptability as a weaning food and for nutrient composition. An acceptable product had 14.3, 6.4, 2.4 and 67.4%, respectively, for its protein, fat, ash and carbohydrate contents. Values for calcium, phosphorus and and iron contents were 59.6, 187.5 and 2.4 mg/100 g, respectively, while the most predominant fatty acids were linoleic, oleic and palmitic acids. The product, which had a chemical score of 85.34 for its protein value, was limiting in threonine.

The proximate composition, minerals, amino acid profiles, grain protein contents of Pennisetum typhodies (Burm.f.) Stapf & Hubbard were analysed. The crude protein was 12.3%, fat 5.3% and ash 2.4%. The grains contained similar amounts of phosphorus, calcium and iron as compared to some Indian and African millets. Amino acid analysis indicated the presence of at least 17 amino acids including most of the essential ones. They were also characterized by the presence of sufficient quantities of essential amino acids and limiting amino acids. Comparisons were made with the results reported by FAO/WHO, the seed proteins showed the essential amino acid leucine was highest, while isoleucine and valine were within the range, but threonine, lysine and the sulphur containing amino acids were lower. In general the results indicate that this grain has a good nutritive value.

1. Ducklings were given diets with vegetable protein (VP) and 0 or 600 g rice bran/kg; fish meal (60 g/kg) and a phytase (+, -) were added to the diets (VP + AP). An additional 40 g soyabean meal/kg was added to the diet with rice bran (VP ++). Amino acid digestibility and mineral retention were measured in the lower ileum of ducklings killed at 23 d of age. Acid insoluble ash was used as an inert marker. Trypsin and amylase activities were also measured and weights of the pancreas and small intestine recorded at slaughter. 2. Addition of soyabean meal (VP ++) to the diet with rice bran improved growth rate and food intake compared to the diet without (VP) and gave the same food intake and growth rate as the comparable basal diet (VP) without rice bran. Fish meal improved growth rate on the diets without rice bran and improved food intake on this diet (VP + AP). Rice bran depressed growth rate and food conversion ratio (FCR); protein source affected growth rate, food intake and FCR; phytase increased food intake only. There were several interactions. 3. Determined total amino acid composition of the diets appeared to meet the essential amino acid requirements of ducklings. Rice bran depressed the ileal digestibility of virtually all amino acids and phytase had no direct effect, although there were interactions. Fish meal addition to diets with rice bran improved the apparent digestibility of several essential amino acids as well as that of dry matter and crude protein. 4. Ileal retention of some minerals and tibia ash content were reduced by rice bran. Fish meal and phytase inclusion increased P retention and ash in tibia. 5. Higher intestinal trypsin activity and increased pancreas size were seen in ducklings on diets with rice bran compared to those without. Intestinal amylase activity was reduced in ducklings given rice bran, probably because of its low starch content. 6. The stimulating effect of fish meal on duckling performance was probably caused in part by the improvement in the digestibility of some amino acids. The addition of small amounts of minerals in fish meal may have increased mineral retention. Phytase gave benefits anticipated from our previous work, but also improved lysine and threonine digestibility in diets containing vegetable protein only.

1. The apparent ileal and excreta digestibilities of amino acids in 15 samples representing 12 food ingredients were determined using 5-week-old male broiler chickens. The ingredients included 3 samples of cereals (wheat, maize and sorghum), 6 samples of plant protein meals (soyabean meal, cottonseed meal, canola meal and sunflower meal) and 6 samples of animal protein meals (meat meal, meat-and-bone meal, feather meal and fish meal). 2. The test ingredients were incorporated as the sole source of dietary protein in assay diets. Each diet was offered ad libitum to 3 pens (4 birds/pen) from d 35 to d 42 post-hatching. Total collection of excreta was carried out during the last 4 d. All birds were killed on d 42 and the contents of the lower half of the ileum were collected. Apparent ileal and excreta amino acid digestibilities were calculated using acid-insoluble ash as the indigestible marker. 3. The influence of site of measurement was found to vary among food ingredients, among samples within an ingredient and among different amino acids within an ingredient. Ileal amino acid digestibility values were similar in some ingredients, but significantly lower or higher in others than the corresponding excreta values. 4. Average ileal and excreta amino acid digestibilities in sorghum and maize were similar, but significant differences were observed for individual amino acids. In contrast, ileal amino acid digestibility values were higher than the corresponding excreta digestibility values in wheat. 5. The average ileal and excreta digestibilites of amino acids in the 3 soyabean meal samples were similar although small, but significant differences were noted for individual amino acids. Site of measurement had no effect on the digestibility of amino acids in canola meal. Digestibilities of valine, isoleucine, phenylalanine, histidine, glutamic acid, alanine and tyrosine in sunflower meal and those of valine, methionine, isoleucine, leucine, lysine, glutamic acid and alanine in cottonseed meal were lower by excreta analysis. 6. Digestibilities in animal protein meals, with the exception of blood meal and fish meal, were consistently higher by excreta analysis. Ileal-excreta differences in individual amino acid digestibilities were more evident in feather meal, meat meal and meat-and-bone meal. 7. Threonine and valine were the indispensable amino acids that were more frequently influenced by the site of measurement. Of the dispensable amino acids, aspartic acid, serine, glutamic acid and alanine were the most affected. 8. Differences determined between ileal and excreta digestibilities in the present study clearly demonstrate that amino acid metabolism by hindgut microflora in chickens may be substantial and that digestibilities measured in the terminal ileum are more accurate measures of amino acid availability than those measured in the excreta.

Four accessions of the under-utilized legume, velvet bean (Mucuna pruriens var. utilis (Wall. ex Wight) Bak. ex Burck), collected from three different locations of Western Ghats, South India were analysed for proximate composition, mineral profiles, the protein fractions, amino acid profiles of total seed protein, in vitro protein digestibility and certain anti-nutritional factors to determine their potential as an alternative source to alleviate protein-energy-malnutrition among the people of South India. The major findings of the study were as follows: crude protein ranged from 20.2-29.3%, crude lipid 6.3-7.4%, total dietary fibre 8.7-10.5%, ash 3.3-5.5% and carbohydrates 49.9-61.2%. The energy level of the seed (1562-1597 kJ 100 g-1 DM) was comparable with commonly consumed Indian pulses. Mineral profiles, viz. sodium, potassium, calcium, magnesium, phosphorus, iron, copper, zinc and manganese ranged from 43.1-150.1, 778.1-1846.0, 393.4-717.7, 174.9-387.6, 98.4-592.1, 10.8-15.0, 0.9-2.2, 5.0-10.9, 3.9-4.3 mg 100(-1) seed flour, respectively. The data on seed protein fractions revealed that the globulins constitute the major bulk of the seed protein as in most legumes. Profiles of amino acids of total seed proteins detected in the present study revealed that they contain relatively higher levels of all essential amino acids except threonine, leucine and lysine in black-coloured seed coat accessions and phenylalanine and tyrosine in white-coloured seed coat accession compared with the FAO/WHO (1991) requirement pattern. The in vitro protein digestibility of the legumes under study ranged from 72.4-76.9%. Anti-nutritional substances like total free phenolics, tannins, L-DOPA, trypsin inhibitor activity and phytohaemagglutinating activity also were investigated. The detected anti-nutritional factors probably have little nutritional significance if the beans are properly processed.

Seeds of Galactia longifolia Benth. (Fabaceae), locally known as Kaattukollu in Tamil language, used as food by Malayali tribals in the Kolli hills of Namakkal District, Tamil Nadu in South India were analysed for proximate composition, total (true) seed proteins, amino acid composition, fatty acid composition, minerals and antinutritional factors. Crude protein, crude fat, ash and nitrogen free extractives constitute 25.56%, 6.18%, 5.12% and 56.15%, respectively. The caloric value of 100 g dry matter of seed material is 1,601 KJ. The essential amino acids, tryptophan, leucine + isoleucine, arginine and threonine are present relatively in large quantities. The unsaturated fatty acids constitute more than 60%. The seeds are very rich in potassium, magnesium, calcium and phosphorus. Antinutritional factors such as total free phenols, tannins, L-DOPA, hydrogen cyanide and phytic acid is present in minute quantities. The seed meal is consumed after eliminating all the antinutritional factors using the conventional method of soaking seeds in water, boiling with water and decanting for four times by Malayali tribals.

Two experiments, each with 39 high-lean-gain potential barrows, were conducted to evaluate the organ weights, body chemical composition, and tissue accretion rates of pigs fed corn-soybean meal diets (CONTROL) and low-protein diets supplemented with crystalline lysine, threonine, tryptophan, and methionine either on an ideal protein basis (IDEAL) or in a pattern similar to that of the control diet (AACON). Amino acids were added on a true ileally digestible basis. The initial and final BW were, respectively, 31.5 and 82.3 kg in Exp. 1 and 32.7 and 57.1 kg in Exp. 2, and pigs were fed for 55 and 27 d in Exp. 1 and 2, respectively. In Exp. 1, the CONTROL and IDEAL diets were offered on an ad libitum basis, or by feeding 90 or 80% of ad libitum intake. In Exp. 2, the CONTROL, IDEAL, and AACON diets were offered on an ad libitum basis, or by feeding 80% of the ad libitum intake. Three pigs were killed at the start of the experiments and three from each treatment were killed at the end of each experiment to determine body chemical composition. In both trials, the whole-body protein concentration (g/kg) and the accretion rates of protein (g/d) were greater (P < 0.05) for pigs fed the CONTROL than for pigs fed the IDEAL and AACON diets. In Exp. 1, pigs fed the CONTROL diet had a trend (P < 0.10) for greater water and lower lipid concentration and had greater (P < 0.05) water and ash accretion rates. Whole-body protein concentration was greatest (P < 0.05) in pigs fed at 80% of ad libitum, but protein, water, and ash accretion rates were greatest (P < 0.05) in pigs allowed ad libitum access to feed. In summary, pigs fed the IDEAL and the AACON diets had less protein in the body and lower protein accretion rates than pigs fed the CONTROL diet. It seems that reductions in protein deposition in pigs fed the IDEAL and AACON diets may have been due to a deficiency of one or more essential amino acids or possibly to increases in the NE for metabolic processes leading to increases in adipose tissue deposition.

Four accessions of the lesser-known legume, Cassia obtusifolia L. (Sickle pod), collected from four different agroclimatic regions of Western Ghats, were evaluated for agrobotanical traits and chemical composition. Among the four accessions, the Keriparai accession had the highest values for plant height (cm), number of flowers per cluster, number of pods per cluster, pod length (cm), seeds per pod, seed weight (g) per pod and seed recovery percentage. Crude protein ranged from 18.56-22.93%, crude lipid was between 5.35-7.40%, crude fiber ranged from 6.83-9.45%, ash content ranged from 5.14-5.83% and carbohydrate varied from 57.00-60.69%. Globulins constituted the bulk of the seed protein as in most legumes. Mineral profiles, viz., sodium, potassium, calcium, magnesium, phosphorus, iron, copper, zinc and manganese ranged from 42.92-84.83, 758.05-1555.79, 559.92-791.72, 456.36-709.47, 629.13-947.79, 8.42-12.35, 0.93-2.06, 10.60-30.04 and 2.12-4.12 mg/100 g seeds flour, respectively. Seed proteins of all accessions exhibited relatively high levels of non-essential and essential amino acids, with the exception of threonine. The in vitro protein digestibility of the legume ranged from 74.66 to 81.44%. Antinutritional substances such as total free phenolics ranged from 0.34-0.66%; tannins were between 0.47-0.60%; L-DOPA content ranged from 0.98-1.34%; trypsin inhibitor activity varied from 11.4-13.5 TIU/mg protein and chymotrypsin inhibitor activity ranged from 10.8-12.3 CIU/mg protein. Phytohemagglutinating activity also was assayed. In conclusion, the accessions of C. obtusifolia, collected from Western Ghats, South India, could serve as a low-cost source of some important nutrients for humans. The antinutritional factors might have little nutritional significance, if the seeds are processed properly.

A study was conducted to evaluate the nutrient content and variability of distiller's dried grains with solubles (DDGS) originating from new (less than 5 yr old) ethanol plants in Minnesota and South Dakota. Ten plants (8 MN, 2 SD) participated in the study, submitting a total of 118 samples. Samples were collected every 2 mo from ten ethanol plants in the Minnesota-South Dakota (MNSD) region from 1997 to 1999 and were analyzed for amino acid levels, DM, CP, crude fiber, crude fat, ash, ADF, NDF, Ca, P, K, Mg, S, Na, Zn, Mn, Cu, and Fe analysis. Digestible energy (DE), ME, and NFE levels were also calculated. Means (dry-matter basis) and coefficients of variation for each nutrient among all plants during 1997 to 1999 were DM (88.9%, 1.7%), CP (30.2%, 6.4%), crude fat (10.9%, 7.8%), crude fiber (8.8%, 8.7%), ash (5.8%, 14.7%), NFE (45.5%, 6.1%), ADF (16.2%, 28.4%), NDF (42.1%, 14.3%), calculated DE (3,990 kcal/kg, 3.24%), calculated ME (3,749 kcal/kg, 3.28%), Arg (1.20%, 9.1%), His (0.76%, 7.8%), Ile (1.12%, 8.7%), Leu (3.55%, 6.4%), Lys (0.85%, 17.3%), Met (0.55%, 13.6%), Phe (1.47%, 6.6%), Thr (1.13%, 6.4%), Trp (0.25%, 6.7%), Val (1.50%, 7.2%), Ca (0.06%, 57.2%), and P (0.89%, 11.7%), respectively. Among the amino acids analyzed, Lys was the most variable (CV = 17.3%), followed by Met (CV = 13.6%). Nutrient levels of MNSD DDGS were higher in crude fat, NDF, DE, ME, P, Lys, Met, and Thr and lower for DM, ADF, and Ca than NRC (1998) values. Nutrient values differed between years for ash, DE, Mn, Zn, Cys (P < 0.10), Fat, TDN, ME, Met, Ile (P < 0.05), Ca, P, K, Mg, and Cu (P < 0.01). These results suggest that gross energy; P; and total Lys, Met, and Thr levels are higher in DDGS from MNSD ethanol plants compared to published values and chemical analysis values of a DDGS sample obtained from an older Midwestern plant.
