CV: Coefficient of variation; WSC: water soluble carbohydrate; NFC + EE: estimated non-fiber carbohydrate and ether extract, based on methods described in Hall (2015); Fraction B2: fraction of potentially digestible fiber, obtained by the difference between NDFap and iNDF; iNDF: indigestible neutral detergent fiber. Abstract. (2009) observed yield loss lower than 50% in the first crop and higher than 50% in the second crop, which was due to water deficiency during the grain filling phase. 0.0 grams trans fat. Sweet sorghum cultivars presented lower ash content, probably because of the higher stem proportion of these cultivars. The lower levels of fraction B2 observed for silages of grain sorghum cultivars BRS 308 and BRS 310 and forage sorghum cultivar BRS 655 in the first crop might be due to a higher proportion of panicles, with lower NDF content. However, these authors demonstrated that the iNDF content obtained with the in situ incubation method had a better relationship with the digestibility of feed OM. Samples containing dishes were placed in the drying oven and dried for 1 h at 130°C/until the constant weight of the sample is maintained. [ Links ], ZHANG, S. J. et al. Sorghum is a crop that stands out as an alternative to corn due to lower soil fertility demand and increased tolerance to drought. Topics included on-farm storage, maximizing economic yield through fertility and managing weeds and insects. [ Links ], SNIFFEN, C. J.; O’CONNOR, J. D.; VAN SOEST, P. J. Plot treatments consisted of six different purpose sorghum cultivars (BRS 308 and BRS 310, grain sorghum; BR 655 and BRS 610, forage sorghum; and BRS 506 and CMSXS 647, sweet sorghum). Journal of Applied Sciences Research, 3(10):1141-1145, 2007. International Journal of Food Sciences and Nutrition 65(5):539-546. The facilities available in the food science lab of the Melkassa center of EIAR were used. The crude fiber content determination was performed according to the AOAC methods [6]. An important function of zinc is an essential cofactor of more than 70 enzymes [46]. Antioxidant-rich Certain types of sorghum grain are rich in antioxidants, which may help lower your risk of cancer, diabetes, heart disease and some neurological diseases. We assure that the data availability is a must and all the results are available. Albuquerque et al. The value was estimated by the following equation [8]: Enter your own food Set category preferences . Zinc deficiency caused dermatitis, growth retardation, diarrhea, mental disturbances, and recurrent infections [48]. 1.2 grams saturated fat. Sorghum bicolor (L). The experimental design was a randomized block with a split-plot arrangement and four replications. It is considered one of the potential crops to alleviate the challenges of recurrent drought in Africa. 2020, Article ID 8243617, 11 pages, 2020. https://doi.org/10.1155/2020/8243617, 1Food Science and Nutrition, Ethiopian Institute of Agricultural Research, P.O. Sorghum is widely used in Ethiopia for human consumption, and it is considered one of the cheap sources of protein. Associative effects of ensiling mixtures of sweet sorghum and alfalfa on nutritive value, fermentation and methane characteristics. [ Links ], SCHOFIELD, P.; PITT, R. E.; PELL, A. N. Kinetics of fiber digestion from in vitro gas production. The standard method of [6], wet digestion method, was used; 0.5 grams of flour was taken and digested with 5 ml conc. Iron and zinc deficiency, a common nutritional disorder, is a substantial factor in health problems all over the world especially in the developing and low-income countries [48]. In the second crop, the sweet sorghum cultivars BRS 506 and CMSXS 647 had lower iNDF content than the other cultivars did. Its deficiency is ranked in the top five risk factors of disease and death in developing countries [47]. INTRODUCTION. O sorgo é uma cultura que se destaca como alternativa ao milho devido a menor exigência em fertilidade do solo e maior tolerância ao déficit hídrico. (1990) showed that silages of sorghum harvested at the soft dough stage of development contains 8 to 12% CP. Tannin content of sorghum (mg/100 g) and food energy (kcal/g) in dry base. The in vitro procedure proposed by Tilley and Terry (1963) for determining the digestibility of food is the most widespread technique utilized in ruminant nutritional studies, owing to its low cost, quickness, and uniformity of results. Iron (Fe) is a core element in the synthesis of hemoglobin and myoglobin [43]. The Soxhlet extraction apparatus was assembled and filled with petroleum ether spirit to a half capacity of the volume of the flask before the fat of the sample is extracted. In the case of sorghum, protein is less digestible than that of other cereals, thus reducing the bioavailability of the protein. “Mg” concentration of this study varied between 207.53 mg/100 g and 62.09 mg/100 g. The flasks were maintained in a water bath at 39 °C. Differences between sorghum varieties were significant () for all measured parameters. Objetivou-se avaliar a composição bromatológica e a digestibilidade in vitro da silagem de cultivares de sorgo de diferentes propósitos, em duas épocas de cultivo. Zhang et al. “P” concentration ranged from 112.554 mg/100 g (Melkam) to 367.965 mg/100 g (Macia). 40 (1):23-32. Multiple phenolic hydroxyl groups of tannins may form stable complexes with protein, metal ions, and other macromolecules like polysaccharides [35, 36] and will reduce the digestibility of the proteins and the availability of the nutrients in the gut. Sign up here as a reviewer to help fast-track new submissions. Phosphorus (P), zinc (Zn), iron (Fe), calcium (Ca), magnesium (Mg), potassium (K), and sodium (Na) contents are shown in Figures 1 and 2. Samples of this study were cleaned manually from dust particles, damaged seeds, and strange materials. Proteins of cooked sorghum are much less digestible than the proteins of other similarly cooked cereals such as wheat and maize. An experiment was carried out to characterize the proximate compositions and antinutritional and mineral contents of sorghum varieties released for production by the Ethiopian sorghum improvement programme. [ Links ], FARINELLI, R. et al. The results of “P” in this experiment are consistent with reports of [41, 42] who reported “P” concentration values ranging from 1498 mg kg-1 to 3787.25 mg kg-1 and 2505.83 mg kg–1 to 3453 mg kg–1. Successful Silage. Protein crosslinking is the main factor that affects the low quality of sorghum protein digestibility [29]. Different tannin concentration of sorghum was previously reported by [37, 38] who found 10 mg/100 g to 351 mg/100 g and 0.021 to 0.681%. The composition and output of sheep’s saliva. In this study, important micronutrient mineral contents were investigated including phosphorus (P), magnesium (Mg), potassium (K), and sodium (Na). Accordingly, [15, 23] report fiber content ranging from 1.0 to 3.4% and 0.90 to 4.20%. Sorghum is approximately 10% protein, and is a rich source of the B-group vitamins. Evaluation of a mathematical model of digesta and in vitro simulation of rumen proteolysis to estimate the rumen undegraded nitrogen content of feedstuffs. The silage of forage sorghum cultivar BRS 655 has higher content of non-fiber carbohydrate and lower level of potentially digestible fiber, at both crop period, with high nutritional value. Â. CV: Coefficient of variation. Zhang et al. Sorghum is a gluten-free cereal and forms the staple diet of a majority of the populations living in the semi-arid tropics. Os tratamentos da parcela corresponderam a seis híbridos de sorgo de diferentes propósitos (BRS 308 e BRS 310, graníferos; BR 655 e BRS 610, forrageiros; BR 506 e CMSXS 647, sacarinos). where is the weight of the receiver flask and fat deposit, is the weight of the empty receiver flask only, and is the weight of the sample used. [ Links ], MACHADO, F. S. et al. Then, digested samples were distilled by using Kjeldahl distiller, and the distilled steam gas (ammonia) was collected with 25 ml of the mixture of 2% boric acid mixed indicator of bromocresol green plus methyl red. The sample-containing tube was placed on a mechanical shaker for 24 h at room temperature, and then, the tube was centrifuged at 1000g for 5 minutes. Moreover, the study in [22] reported that fat value varied from 2.l to 7.6%. Weed control was carried out by manual weeding. A. Onimawo, F. Oteno, G. Orokpo, and P. I.

DM: dry matter; OM: organic matter; CP: crude protein; NDF: neutral detergent fiber. Regarding feed digestibility, silages of sweet sorghum cultivars BRS 506 and CMSXS 647 presented higher IVDDM than the other cultivars (Table 6), probably because of the higher level of WSC and lower content of iNDF. Journal of Animal Science. [ Links ], AMER, S. et al. where is the sample absorbance, is the blank absorbance, is the density of the solution (0.791 g/ml), is the weight of the sample in gram, and 10 is the aliquot. Also, in [39], the iron concentration study on 12 varieties of sorghum from Tanzania showed iron content in the range of 5.50 mg/100 g to 182 mg/100 g. , Mwasaru , M.A. For forage evaluation, ten plants per plot were collected and chopped to approximately 20 mm in length using a stationary forage cutter. (2008) observed CP content of 10.98% for grain sorghum cultivar Arakan. Silages of sweet sorghum cultivars BRS 506 and CMSXS 647 presented lower estimated lag time than grain and forage cultivars did, possibly because of the higher levels of WSC and NPN observed in these cultivars. Journal of Food Science and Nutrition Research 3 (2020): 217-230. It can easily form a complex with other compounds including carbonates, phosphates, sulfates, oxalates, and phytates. Sorghum is an excellent substitute for wheat flour, and sorghum flour makes a great baking ingredient for anyone who cannot tolerate gluten. The trial was conducted at the Plant Production Department, Federal Institute of Education, Science, and Technology of Rondônia, Colorado do Oeste campus, and chemical analyses and in vitro incubation were performed at the Laboratory of Animal Nutrition, Federal University of Mato Grosso, Cuiabá campus. Sorghum is indeed a gluten free grain, safe for consumption for those with sensitivities [5]. Studies on ruminal saliva. The highest value was recorded from a variety of ESH-3 and the lowest from Karimtams. *Means followed by the same capital letter in the column and by small letters in the row do not differ among themselves by LSD test (p > 0.05). It is a nutrient-rich grain that is high in soluble fiber and antioxidants and may reduce the risk of diseases such as type 2 diabetes. This could be attributed to a moisture level of less than 15% [14]. (2002) evaluated the gas production of sorghum by the in vitro incubation system and observed a positive correlation between soluble sugars and gas production. The low levels of NDF in the forage of sweet sorghum cultivars BRS 506 and CMSXS 647 in the first crop might be due to the high WSC content in these plants, which are characterized by high content of non-structural carbohydrates that remain in the stem and leaves in the form of soluble sugars.
