Macro- and micromineral contents of different quinoa (Chenopodium quinoa Willd.) varieties used as forage by cattle

Abstract

Mineral deficiencies or mineral excess affect livestock production in most regions of the world. For this reason, it is important to know the mineral contents of forages used in animal feeding. Quinoa (Chenopodium quinoa Willd.), which has become a popular grain crop around the world in recent years, is used as forage in animal feeding. This study was carried out to determine the contents of macro-and microminerals and mineral balance in 9 different quinoa varieties. The results of the study indicated that mineral contents of forages show great variation between quinoa varieties. The Cherry Vanilla variety is rich in all minerals except for molybdenum. Potassium, iron, copper, zinc, manganese, molybdenum, and boron concentration in all quinoa varieties are sufficient to meet the requirements of beef cattle. In contrast, sulfur is insufficient in all varieties. The contents of phosphorus, calcium, and magnesium show deficiencies in some varieties. Although there is usually no risk of tetany (K/Ca + Mg) and milk fever (Ca/P) in quinoa forage, these mineral imbalances may be observed depending on variety.

Feed-value of post-harvest quinoa plant sections grown by different cultural applications

“…The previous study findings that K content varied between 2.9 and 3.3% (Kaya and Aydemir, 2020) and 1.5 and 2.3% (Tan, 2020). It was observed that the present study findings were consistent with previous studies and reported ideal K levels.…”

“…Phosphorus content reported in previous studies varied between 0.27 and 0.42 % (Kaya and Aydemir, 2020), 0.7, and 1.8 % (Tan, 2020) in different quinoa varieties. In the present study, the P content was low since we harvested the crops after physiological maturity and analyzed the residue plant sections after deseeding.…”

“…Certain studies reported that Ca content varied between 1.0 and 3.3 % in 9 quinoa varieties (Tan, 2020) and between 0.83 and 1.27 % in 6 quinoa varieties (Kaya and Aydemir, 2020). Although the previous study findings were consistent with our findings, it was observed that Ca content was lower in various plant species.…”

“…Tetany and Milk fever Tan (2020) analyzed the use of quinoa plants as feed and reported that the tetany risk varied between 1.5 and 3.0 and MF value varied between 0.5 and 3.8% and also, he was reported that intensive use of certain varieties might lead to milk fever risk. It was suggested that the present study findings were higher than the ideal range, and quinoa should not be used alone and at high rates.…”

Investigation of Some Quinoa (Chenopodium Quinoa) Genotypes in Terms of Quality Criteria

“…Mn (manganese) from 14.25 to 45.64 mg kg -1 , Mg (magnesium) from 1713 to 3068 mg kg -1 , Fe (iron) from 65.58 to 530 mg kg -1 , Cu (copper) from 5 to 7 mg kg -1 , Zn (zinc) ranged from 1.27 to 14.28 mg kg -1 (Table 8). Tan (2019) reported that Mn from 49.0 to 161.3 mg kg -1 , Mg from 962 to 2344 mg kg -1 , Fe from 265.9 to 498.6 mg kg -1 , Cu from 27.4 to 92.5 mg kg -1 , Zn from 41.3 to 85.2 mg kg -1 ranged. The mineral content of quinoa was collected in the outer bran layer, such as cereals (Repo Carrasco Valencia et al, 2011).…”
