“…Surber et al (2011) reported that crude fiber concentration represented by ADF and NDF is one of the most important parameters determining the forage quality. In the present study, there were significant effects of clipping date and germplasm by clipping date interaction on the crude fiber concentration (Table 2).…”

“…Although forage nutritive value is positively related to animal performance (Adesogan et al, 2011; Coleman and Moore, 2003; Lake et al, 1974), species or varieties for winter forage production have not been selected on the basis of their nutritive value. In addition, forage nutritive value has usually been neglected in breeding programs despite the large‐scale importance of winter forage crops (Foster, 1987; Siahsar et al, 2009; Surber et al, 2011). Crude protein (CP) is one of the most important factors that determine nutritive value of forage (Surber et al, 2011).…”

Variations of Forage Yield and Nutritive Value in Winter Rye Germplasm

There has been an increasing use of rye (Secale cereale L.) for winter forage production in the United States because of its good forage yield, nutritive value, and winter hardiness. However, limited information on forage rye is available. To identify variations and germplasm with superior forage yield and/or nutritive value, winter rye germplasm, including elite cultivars and advanced breeding lines, were evaluated during two growing seasons. Effects of germplasm, clipping date, and germplasm by clipping date interactions were significant for dry matter yield (DMY). Clipping date and germplasm by clipping date interactions were significant for crude protein (CP), minerals, and nutritive value, but germplasm effect was not significant. Across the environments, seasonal DMY ranged from 789 kg ha−1 for ThunderGreen at the first clipping to 3733 kg ha−1 for NF97352 at the first clipping. Crude protein concentration varied from 17.7 to 27.9% for ThunderGreen at the third and first clipping, respectively. Cumulative DMY ranged from 5301 kg ha−1 for ThunderGreen to 8114 kg ha−1 for NF95319B. The results of this study identified significant variations in DMY and nutritive value among the rye germplasm, which may provide useful information for rye breeding programs for winter forage production and livestock producers.

“…The crude fiber content represented as ADF or NDF is one of the most important parameters determining the forage quality because the ADF and NDF level in forage are strongly and negatively correlated with forage digestibility (Surber et al 2011). Collar and Aksland (2001) also stated that an energy value of the forage is positively related to digestibility of the ADF and NDF.…”

Wheat (Triticum aestivum L.) has been widely grown as a winter forage crop in the southern Great Plains. However, development of wheat cultivars for winter forage production has not been a major goal of wheat breeding programs in the USA. Also, little information on forage yield and nutritive value of currently grown wheat varieties is available. The objective of this study was to test 15 wheat varieties to compare their forage yield and nutritive value and to identity superior varieties for winter forage production. The field trials were conducted during three growing seasons in southern Oklahoma. There were significant effects of variety, clipping-date, and environment for mean forage yield. The mean forage yield of the varieties ranged from 2,200 kg ha -1 for NF95134A to 1,655 kg ha -1 for Forage Max. The crude protein content varied from 24.2 to 20.8 %. When mean forage yield and crude protein yield were considered, NF95134A was the best variety for the tested regions. However, when low detergent fiber content and high energy value were considered, Forage Max was the best variety in the tested environments. When forage production, especially during the coldest months December through February was considered, NF96107A and NF96131 produced the best forage yield. This study showed that significant differences in forage yield and nutritive value existed among the winter wheat varieties and the results of the study could provide useful guidelines for livestock producers and for forage wheat breeding programs.

Forage and cattle production during organic transition in dual‐purpose wheat systems

Dual‐purpose wheat (Triticum aestivum L. emend. Thell.) production systems (i.e., graze and grain) are prevalent in the U.S. Southern Great Plains region, though few of them are managed organically and organic research is very limited, particularly on forage and grazing aspects of the system. Therefore, the objective of this 3‐year systems study (2018–2021) conducted near Vernon, TX, was to compare forage production, forage nutritive value, and cattle gains in transitional organic and conventional dual‐purpose wheat systems. Forage data were collected each year during the early‐season dual‐purpose grazing period until maturity. Monthly standing crop biomass, rate of forage production, and forage nutritive value did not differ during the grazing period between systems in any year. Limited early‐season precipitation resulted in slow forage growth in all years and inadequate forage production to support grazing in 2 of 3 years. In the year when grazing occurred (2018–2019), cattle performance did not differ between systems. Following the dual‐purpose grazing period, the organic system trended toward lower forage production and crude protein concentration than the conventional system, suggesting that in a “graze‐out” scenario (i.e., season‐long grazing and no grain production), the organic system might not support as much cattle production. The late‐season divergence between systems could likely be minimized or eliminated by improving N availability in the organic system. Agronomic viability of the organic system, in terms of forage production, nutritive values, and cattle gains, was supported by its overall similarity to the conventional system.
