“…The WW had greater ( P < 0.05) DM than WR (Table 2), which increased during the grazing period for both forages (Fig 2). Previous studies agree with greater DM for WW and an increase in DM during the growing period [23, 28]. The abrupt increase in DM at the end of the grazing period may have been caused by little precipitation in the month of June [28] (Table 1).…”

2The objective of this study was to assess yield, nutritional quality, and fatty 3 acid compositions of winter rye (Secale cereale) and winter wheat (Triticum 4 aestivum) forages for grazing cattle (Bos taurus) in an organic system. The rye 5 and wheat were established on two 4 ha plots in September 2015. Six groups of 6 dairy steers rotationally grazed rye (n = 3) or wheat (n = 3) plots divided into 7 seven paddocks (n = 14) from April to June 2016. Forage samples (n = 96) taken 8 prior to paddock grazing were used to analyze forage characteristics. Mixed 9 models with fixed factors of forage, date, and their interaction, a random subject 10 factor of group nested in paddock, and a repeated effect of date were used for 11 each outcome. The linear effect of date on fatty acids was obtained by 12 substituting date as a continuous variable. The mean forage yield for rye was 13 greater (P < 0.05) than wheat (mean ± standard error; 2840 and 2571 ± 82 kg ha -14 1 , respectively). However, rye yielded less in the latter part of the grazing period. 15 Wheat (19.3 ± 0.30% DM) had greater (P < 0.001) crude protein than rye (17.6 ± 16 0.30% DM). In general, crude protein, digestibility, and minerals decreased 17 during the grazing period. Wheat (66.3 ± 0.54 g 100g -1 ) had greater (P < 0.001) 18 alpha-linolenic acid (18:3n-3) concentration than rye (63.3 ± 0.54 g 100g -1 ). 19 Although both forages decreased (P < 0.05) in alpha-linolenic acid concentration, 20 wheat decreased 2.49 times more (P < 0.001) per d compared to rye forage. 21 Winter rye and winter wheat forages are viable for cattle grazing. Producers 3 22 should initiate early grazing to maximize protein, digestibility, and alpha-linolenic 23 acid intake while the forages are immature. 24 61 As pasture-based beef and dairy industries grow, it is important to assess 62 alternative forages and understand their impacts on production and nutritional 63 quality for grazing. Therefore, the objectives of this study were to assess and 64 compare WR and WW pastures for forage yield, dry matter (DM), nutritional 65 quality, mineral composition, and FAs during the grazing season. 5 66 Materials and methods 67

“…For example, [54] reported that crossbred lambs that grazed winter wheat had impressive liveweight gains (320-360 g/day) in Australia. Similarly, early spring liveweight gains of weaned merino lambs that consumed wheat (227 g head/d) and oat (221 g head/d) from tillering to booting stage were similar to the liveweight gains of lambs fed on a concentrate feed diet (256 g head/d) in Turkey [53]. At the vegetative phase, the energy content of dual-purpose crops is consistently measured at greater than 12 MJ ME/kg DM [35].…”

“…Given the widespread use of cereal straws in the diets of livestock in the West Asia-North Africa region, any improvement in the feeding value of these crop residues would have substantial effect on ruminant productivity. The high nutritive value of immature winter annuals is aligned with the most productive period of growing lambs [44] [53]. For example, [54] reported that crossbred lambs that grazed winter wheat had impressive liveweight gains (320-360 g/day) in Australia.…”

Meeting the growing demand for animal-sourced food, prompted by population growth and increases in average per-capita income in low-income countries, is a major challenge. Yet, it also presents significant potential for agricultural growth, economic development, and reduction of poverty in rural areas. The main constraints to livestock producers taking advantage of growing markets include; lack of forage and feed gaps, communal land tenure, limited access to land and water resources, weak institutions, poor infrastructure and environmental degradation. To improve rural livelihood and food security in smallholder crop-livestock farming systems, concurrent work is required to address issues regarding efficiency of production, risk within systems and development of whole value chain systems. This paper provides a review of several forage basedstudies in tropical and non-tropical dry areas of the developing countries. A central tenet of this paper is that forages have an essential role in agricultural productivity, environmental sustainability and livestock nutrition in smallholder mixed farming systems.

“…The major constraint for the livestock component of the farming system is scarcity of high-quality feedstuffs, particularly in the autumn and winter sea-sons. Small grain winter cereals at the early vegetative stage offer high nutritive value forage for ruminants (Coblentz and Walgenbach, 2010) and provide live weight gains that are similar to those of concentrates (Keles et al, 2016). Grazing of immature cereal crops may also have a positive impact on the nutritive value of the regrown forage material (Francia et al, 2006;Jacobs et al, 2009;Keles et al, 2013).…”

Dual-purpose management of winter cereals for grazing and grain production provides highly nutritive forage for ruminants in the spring and may positively affect straw feeding value. A 2-yr study investigated the effect of spring defoliation of triticale, wheat, and rye at the tillering and stem elongation stages on total biomass, grain yields, and straw quality. Furthermore, straws of spring-defoliated and undefoliated (control) cereal crops were evaluated for nutritional value and voluntary intake as a means of assessing the efficiency of dual-purpose management systems from the winter feeding context as well. The feeding study consisted of 9 total mixed rations (TMR), each containing 35% triticale, rye, or wheat straw obtained under 3 spring-defoliation regimens. The TMR were individually fed to fifty-four 1-yr-old Anatolian Merino ewes for 28 d. Defoliation of the crops at tillering did not affect the total biomass production or grain yields. However, biomass and grain yields were reduced ( < 0.01) by 55 and 52%, respectively, in crops defoliated at stem elongation. Straw of spring-defoliated cereals had less NDF and ADF concentrations ( < 0.01) but greater CP ( < 0.01), nonfiber carbohydrates ( < 0.01), and ME concentrations ( < 0.01) compared with straw from undefoliated crops. The increase in the nutritive value of straw led to greater nutrient digestion ( < 0.01) and intake of DM and OM of ewes ( < 0.01). However, sheep live weight gain did not differ among treatments ( > 0.77). This study indicated that straw feeding value and digestibility can be increased through spring defoliation.

Abstract: Wheat and oats, and to a lesser extent triticale, provided higher quality forages than barley and rye. All cereal species had poor feeding qualities between ear emergence and milk stages (Z 71-75). © 2016 Society of Chemical Industry.
