“…Part of this might be because the yield of oats was higher and the swaths in the field therefore thicker than those of six-rowed barley (data not shown). The DM content of oats at the early dough stage was not only lower than that of the barley in this study, but was also lower than the 357 to 368 g/kg reported in previous studies (Bergen et al, 1991;Mustafa and Seguin, 2003;Nadeau, 2007). The ash concentrations varied between silages; they were higher in oats and six-rowed barley harvested at the heading and early milk stages of maturity than in the other silages.…”

“…The CP, NDF, ADF and WSC concentrations decreased, whereas starch and lignin concentrations increased, with increasing maturity stage of the harvested crop. The WSC of the fresh crop of oats and six-rowed barley was somewhat lower than in other studies (Bergen et al, 1991;Nadeau, 2007). The two-rowed barley had WSC concentrations similar to that reported by Nadeau (2007) for barley.…”

“…The ash concentrations varied between silages; they were higher in oats and six-rowed barley harvested at the heading and early milk stages of maturity than in the other silages. Previous data on ash concentrations in oats and barley at different maturity stages vary between 50 and 90 g/kg DM (Bergen et al, 1991;Khorasani et al, 1997;Nadeau, 2007). The high ash concentrations in six-rowed barley and oats at the heading and early milk stages were a result of the very dry weather in Umeå before these harvests.…”

This study evaluated the digestibility of whole-crop cereal silage (WCCS) made from oats and six-rowed barley harvested at the heading, early milk and early dough stages, and two-rowed barley harvested at the early milk and early dough stages of maturity. The eight WCCSs were fed to 32 Swedish Red heifers in a changeover design over three periods of 28 days each. The heifers were first fed ad libitum for 17 days and then at 0.95 of ad libitum for 11 days of each period. During the last 5 days all faeces and orts were collected to determine the digestibility of the silages. Only the maturity stage effect was significant for the WCCS organic matter (OM) digestibility and the average OM digestibility was higher at the heading stage (698 g/kg) than at early milk (647 g/kg) and early dough (652 g/kg) stages of maturity. For neutral detergent fibre (NDF) digestibility the crop 3 maturity stage effect was significant. The NDF digestibility decreased from the heading to the early milk stage for both six-rowed barley (746 to 607 g/kg) and oats (698 to 596 g/kg). There was no further significant decrease in NDF digestibility for six-rowed barley at the early dough stage (577 g/kg), but for two-rowed barley it decreased from the early milk (682 g/kg) to the early dough (573 g/kg) stage, and also for oats the NDF digestibility was lowest at the early dough stage (507 g/kg). The decrease in NDF digestibility during maturation was to a large extent compensated by an increase in starch concentration in the crops. The starch digestibility was lower for six-rowed barley at early dough stage (948 g/kg) than at early milk stage (977 g/kg), and was also lower compared with oats (979 g/kg) at early dough stage. The average crude protein (CP) digestibility was higher at the heading (646 g/kg) and the early milk (642 g/kg) stages than at the early dough stage (599 g/kg), and oats had higher average CP digestibility (650 g/kg) than six-rowed (613 g/kg) and two-rowed (624 g/kg) barley. Delaying the harvest of WCCS from the heading to the early milk and dough stage of maturity will decrease the OM digestibility; as a result there is a decreased NDF digestibility.Keywords: Avena sativa, Hordeum vulgare, whole-crop cereal silage, utilization, maturity ImplicationsThis study covers the utilization (digestibility) of whole-crop cereal silages (WCCSs) under some of the conditions used in practice (heifers fed at high intakes). These results can therefore be used by farmers and advisors to predict the energy content (based on the organic matter digestibility) of WCCS harvested within the range of maturity stages investigated in this study, when making feed rations for these kind of animals. The results also show that harvest without a grain processor is also possible at early dough stage without a decrease in starch digestibility, and that conventional grass silage machinery therefore can be used at harvest.

“…La etapa de madurez a la cosecha tiene el mayor efecto sobre el rendimiento de biomasa y la calidad de los cereales (Cherney y Marten, 1982;Bergen et al, 1991).

ResumenCuencas lecheras como la de la Región Lagunera de México requieren opciones forrajeras que proporcionen forraje de calidad y flexibilicen los esquemas de rotación. Veintisiete líneas imberbes de trigo más los testigos Avena Cuauhtémoc, Triticale Eronga 83 y una cebada forrajera experimental imberbe (Narro 95) se evaluaron usando un diseño alfalátice con 3 repeticiones durante el ciclo O-I 2010-2011 con el objetivo de cuantificar la producción de materia seca y el valor nutritivo de sus fracciones. El experimento se sembró manualmente, a chorrillo y en seco usando 120 kg ha -1 , se aplicaron dos riegos de auxilio y a los 118 días después de la siembra se realizó el muestreo de forraje en forma manual, anotando la etapa fenológica, cobertura y altura de planta. La muestra de forraje verde se secó bajo condiciones naturales hasta alcanzar peso constante, registrando la producción de materia seca y procediendo a la separación de hojas, tallos y espigas. Solamente de los genotipos de trigo más productores, más avena y cebada, se homogenizó la materia seca de las repeticiones y se determinó el valor nutritivo para cada fracción. Adicional al análisis de varianza y prueba de medias de las variables de campo, con los valores medios de estas variables y las de valor nutritivo se realizó un análisis de componentes principales (ACP).

Forage mixture productivity and silage quality from a grass/legume intercrop in a semiarid Mediterranean environment

2023

In semiarid environments of the Mediterranean region, intercropping is a sustainable agricultural system of long standing. In this area, the pea (Pisum sativum L.) is one of the most commonly grown legume crops. Little information is available on the quality of silages to be obtained from forage mixtures of pea intercropped with cereals or annual grasses. In this study, two experiments were conducted over the course of two growing seasons in Sicily (Italy) with the aim to determine the biomass production of forage crop mixtures and assess, only in the second experiment, the silage quality of grass and legumes. Four cereals and one annual grass species were grown in pure stand and in mixture with pea, and their main agronomic traits were determined.The land equivalent ratio (LER), competitive ratio, and aggressivity index were also calculated. A number of parameters were considered to assess the quality of silage obtained from fermented biomasses derived from pea-ryegrass (Lolium multiflorum Lam. var. Westerwoldicum) intercropping. In the first experiment, the best performance between the intercrops was recorded for the pea-wheat mixture. The total LER calculated for fodder yields was always greater than 1, indicating crop yield advantages ranging from 2.0% to 47.0%. In the second experiment, the pea-ryegrass mixture appeared to respond well, depending on plant arrangement and seeding ratio factors: the ratios 50:50 and 100:50 showed the greatest crop yield advantages, of 12.0% and 11.0%, respectively. All silages revealed a very good suitability of a pearyegrass intercropping system with high-quality silage production in the Southern Mediterranean region.
