“…Moreover, from an agricultural point of view, guar is an excellent drought tolerant crop, able to be profitably rotated with many crops such as cotton and sorghum (Rao, Tarafdar, Sharma, Kumar, & Aggarwal, ). Guar is mainly grown in India, Pakistan and to a lesser extent in the USA (Sharma, ), but its area of adaptability is expanding also to the irrigated areas of Mediterranean environments (Gresta et al., , ; Sortino & Gresta, ), where appropriate genotypes suitable for this environment have been identified (Gresta, De Luca, et al., ; Gresta, Santonoceto, et al., ). For the above‐mentioned reasons, guar is now assuming a larger role among domesticated plants due to its peculiar functional properties (Badr, Abdelfattah, El‐Sayed, Abd El‐Aziz, & Sakr, ; Srivastava et al., ).…”

SummaryGuar (Cyamopsis tetragonoloba L.) is an interesting summer legume multipurpose crop used for the extraction of seed gum, due to its galactomannan content, and the highprotein by-product, (germ and hull) used for animal feed. The aim of this study was to assess qualitative traits of degummed seeds, named guar meal, of six guar varieties from India, South Africa and USA, grown in a Mediterranean environment (Sicily, Southern Italy), in order to explore their suitability for livestock, and comparing them with the marketed Indian products of guar meals, Churi and Korma. After harvest, seeds were manually degummed and proximate composition was analysed using the official method of analyses, total phenols and tannins by UV spectrophotometry and fatty acids by GC-FID. Qualitative profile of degummed guar seeds (DGS) was significantly (p < .05) influenced by the genotype. Among DGS, Matador showed a high (p < .05) content of protein (518 g/kg), lipids (59.4 g/kg) and the lowest (p < .05) NDF level (181 g/kg) compared to the other varieties. Total phenol content of DGS showed similar values among varieties (2.57 mg gallic acid/g, on average) and with those of guar meal Korma 50%-53% (2.89 mg gallic acid/g) and Korma 56%-58% (2.94 mg gallic acid/g). Tannins were below the instrumental limit of quantification (1.5 mg/g of catechin equivalents) in DGS, as well as in the marketed products. Fatty acid composition was significantly influenced (p < .05) by the genotype. Matador showed the significant highest content of polyunsaturated fatty acids (PUFA) of the n6 series (45.2 g/100 g), whereas India showed the significant (p < .05) highest content of PUFA of the n3 series (3.55 g/100 g), and the significant (p < .05) highest level of n3/n6 PUFA ratio (0.08), and the best (p < .05) Atherogenic Index (0.19) and Thrombogenic Index (0.46). This study shows the interesting nutritional characteristics of degummed guar seeds, underlining that, if the future of the guar gum industries depends largely on the utilization of guar seed meal, this product can be considered a valuable feed resource and a way to increase the income of guar production. K E Y W O R D Sdegummed guar, fatty acids, nutritional indices, proximate composition, tannins, total phenols | INTRODUCTIONThe recent price hike of raw feed ingredients prompted animal nutritionists to formulate economic and efficient feed rations utilizing available agro-industrial by-products and/or exploring nonconventional feed resources able to minimize feed cost (Logaranjanai, Banupriya, & Kathirvelan, 2015). In this scenario, legumes can play a key role not only because they reduce the marked deficit of Among uncommon legumes, guar (Cyamopsis tetragonoloba L.) is an interesting summer multipurpose crop, used for the extraction of seed gum, as animal feed and as green manure (Sharma & Gummagolmath, 2012). The guar gum, contained in its endosperm, consists of a long branching polymer of mannose and galactose, named galactomannans. As a primary product, the guar gum is extensively us...

“…Average (1.6ton/ ha) has been reported by Wong et al, (1997), Ecocrop, (2010). Purushottam Sharma (2009) reported that the Current production of guar seed is 4.3million tons from 2.82 million hectares under cultivation. India produces about 80% of world production, and about 2 million tones of guar meal are produced and utilized in the manufacture of guar gum from the endosperm.…”

This study was carried out to determine the effects of using different levels of Guar korma meal (*GK) on milk yield and milk composition, rumen function of experimental rations fed to sheep and dairy cows. Animals were fed one of from experimental rations, control ration with 0% GK or rations with 5%, 10% and 15% GK. Animals fed rations containing guar korma showed linear decrease (P < 0.05) of total dry matter intake (DMI) with increasing ration guar korma meal level inclusion in rations. Twelve Barki male sheep were assigned randomly into 4 similar groups of 3 animals each to determine the digestibility coefficients, nitrogen balance and nutritive values of experimental rations. Results of digestibility trails showed that there were no significant differences (P< 0.05) in digestibility of DM, OM and CP for ration containing 10% GK compared to the control ration. While, there was significant (P < 0.05) decrease rations containing 5%, 15% guar korma. Similar trend recorded for the nutritive values. However, nitrogen utilization showed positive nitrogen balance with all animals fed the experimental rations. Three cannulated female Barki sheep were used to determined rumen fermentation parameters. The main results showed no significant differences among experimental groups in the values of ruminal pH and NH3-N concentrations, while the highest (P < 0.05) of TVFA'S concentrates were observed with the ration containing 10%GK and the control ration than rations containing 5%,15% guar korma. Dry matter and CP degradability showed significant (P < 0.05) increased for rations containing GK than the control ration. Eight lactating crossbred Friesian cows were used to determine milk yield and milk composition. Cows fed ration containing 5% GK showed slight improvement in milk yield in comparison with the control ration. However Milk fat (%) increased (P < 0.05) for rations containing guar meals compared with the control ration. *GK= guar korma meal

“…Guar (Cyamopsis tetragonoloba (L.) Taub.) is a low-input annual legume species (Gresta et al, 2014), with a springsummer cycle, mainly grown in India (80% of the world's production), Pakistan (15%), Sudan and the United States (Sharma, 2010). It is a self-pollinated crop, extremely drought-tolerant, with good adaptability to a wide range of soil conditions, even though it performs best in sandy soils.…”

Guar (Cyamopsis tetragonoloba (L.) Taub.) is an annual legume with a long crop cycle and high temperature threshold for seed germination (20-21°C). In semi-arid Mediterranean areas, inadequate soil warmth delays guar planting to May/early June and harvest to October-November, when high rainfall hinders seed maturation and lowers gum quality. Nine world guar genotypes (from India, Pakistan, USA, South Africa) were tested for germination capability and speed in response to temperature. All source seeds were field grown in Sicily for use in germination assays. The following temperature regimes were imposed adopting a completely randomized design: A) seven constant temperatures from 5°C to 35°C (5°C increments), and B) two alternating temperatures of 15/10°C and 20/15°C (6h/18h thermoperiod), each consisting of four replicates of 25 seeds. Optimal germination temperatures were always 30 and 35°C, but Indian genotypes also demonstrated substantial germination percentages (33-43%) at constant temperatures as low as 15°C. Mean germination time (MGT) of genotypes India2, Kinman, Lewis, and Monument were 1.1 to 1.7 days at 30 and 35°C. At lower temperatures (15°C), the germination percentage and MGT improved significantly when the seeds were exposed at 20°C for 6 hours a day. In particular, Kinman, India2 and Monument gave good results, achieving 80%, 76% and 66% germination, respectively, with MGTs of 5 days. This alternating temperature regime is typical in soil during the Mediterranean spring. Results may be useful both for farmers to identify optimum timing for guar sowing, and for breeders to cross genotypes that tolerate low germination temperatures with high yielding genotypes.
