“…Lehmen, Fontaneli, Fontaneli, and Santos (2014) analyzed two distinct black oat genotypes and obtained a mean NDF of 74.5%, which is 4.9% higher than our results for the storage period of 60 days and 5.1 and 6.8% lower than those demonstrated for the storage period of 120 and 180 days, respectively. Meinerz et al (2011), in turn, examined three black oat genotypes and reported a mean NDF of 69.6%, which is lower than the results of the present study, regardless of the storage period.…”

ABSTRACT. The objective of the experiment was to evaluate the nutritional composition, dry matter (DM) recovery and aerobic stability of winter cereal silages under different storage periods. The materials used were wheat (Triticum aestivum cv. BRS Gralha Azul), barley (Hordeum vulgare cv. BRS Brau), white oat (Avena sativa cv. URS Guará), black oat (Avena strigosa cv. Embrapa 139) and triticale (X Triticosecale IPR 11), in three storage periods: 60, 120 and 180 days. The experiment was conducted in a 5x3 factorial, completely randomized design, consisting of five forage species and three storage periods, with five replicates. In nutritional assessment, barley silage presented low values of acid detergent fiber (ADF; 331.2, 355.2 and 378.5 g kg DM -1 for 60, 120, 180 days, respectively), high total digestible nutrients (TDN; 558.2, 544.7 and 531.6 g kg DM -1 for 60, 120, 180 days, respectively), high DM recovery and aerobic stability. Wheat and triticale showed a decrease in DM recovery with the increase in storage length, although showed high aerobic stability. The storage period had a different effect on forages; however, storage period above 60 days provided no benefits for the variables evaluated.Keywords: storage, aerobic deterioration, DM recovery.Composição nutricional e estabilidade aeróbia de silagens de cereais de inverno com diferentes tempos de estocagem RESUMO. O objetivo do experimento foi avaliar a composição nutricional, a recuperação de matéria seca (MS) e a estabilidade aeróbia de silagens de cereais de inverno submetidas a diferentes tempos de estocagem. Os materiais utilizados foram o trigo (Triticum aestivum cv. BRS Gralha Azul), cevada (Hordeum vulgare cv. BRS Brau), aveia branca (Avena sativa cv. URS Guará), aveia preta (Avena strigosa cv. Embrapa 139) e triticale (X Triticosecale cv. IPR 11), em três tempos de estocagem: 60, 120 e 180 dias. O delineamento experimental foi inteiramente casualizado em arranjo fatorial 5x3. Na avaliação nutricional, a silagem de cevada apresentou baixos teores de fibra em detergente ácido (FDA; 331; 355 e 378 g kg MS -1 , para 60, 120 e 180 dias, respectivamente) e altos de nutrientes digestíveis totais (NDT; 558; 544 e 531 g kg MS -1 para 60, 120 e 180 dias, respectivamente), além de alta recuperação de MS e estabilidade aeróbia. O trigo e o triticale apresentaram decréscimo na recuperação de MS com o aumento dos dias de estocagem, embora tenham apresentado alta estabilidade aeróbia. O tempo de estocagem influenciou de maneira distinta as forrageiras, no entanto, tempos de estocagem acima de 60 dias não proporcionaram benefícios para as variáveis avaliadas.Palavras-chave: armazenamento, deterioração aeróbia, recuperação de MS.

“…BRS Saturn had 25.93% soluble carbohydrates in its green forage constitution, it showed high ruminal disappearance rate (1.00% time -1 ) and, after 48 hours, it increased to 69.95% degradability. Overall, the values obtained in this study were higher than were those described by Meinerz et al (2011a). figure 2, it is possible to see for most of the evaluated materials parallel trend lines for green forage and for pre-dried silage in the course of the time.…”

This study aimed to evaluate the contents of hemicellulose, cellulose, and lignin, as well as the rates of dry matter degradability in forage and pre-dried silage of different winter cereals harvested at preflowering. The experiment was conducted by the Animal Production Center (NUPRAN), Department of Agricultural and Environmental Sciences, State University of Midwest (UNICENTRO). It is located in Guarapuava -PR, Brazil. The study was part of the Master's Degree in Crop Production. As experimental materials, we used black oat (Avena strigosa) cv. EMB 139 and cv. IAPAR 61; white oat (Avena sativa) cv. IPR and 126 hp. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Triticum aestivum) cv. BRS Umbu and cv. BRS Tarumã; rye (Secale cereale) cv. Temprano and cv. BRS Serrano; and triticale (X Triticosecale) cv. IPR and 111 hp. BRS Saturn. Dry matter degradability was measured by an in situ technique, arranged in a completely randomized block design with three replications (animal), subdivided in subplots. Treatments were the plots and subplots digestion times. The incubation times were 0, 6, 12, 24, and 48 hours. To that end, we used two 24-month rumen fistulated steers with 350 kg average weight. A similarity was observed in the results of both forage and pre-dried silage degradability, displaying the same trends. Barley cv. BRS Brau had the highest hemicellulose content in its composition; however, IPR 111 triticale was showed the highest degradability potential, both for green forage and pre-dried silage.

“…Segundo Meinerz et al (2011b), todas as espécies e genótipos apresentam condições para serem ensiladas e produzirem silagens com perfil fermentativo desejável, porém, cada uma possui características produtivas e nutricionais distintas (Tabela 1). autores encontraram para ambos os ciclos a mesma altura média de planta (126 cm), que mostra também, a importância de se conhecer a cultivar com a qual se trabalha.…”

RESUMO.A produção de silagem pré-secada de melhor custo benefício aliando alta produção, valor nutricional e custo de produção são fundamentais para sobrevivência no sistema produtivo. Nesse contexto, os cereais de inverno ganham destaque por serem excelentes para a oferta in natura, ou seja, em pastejo e terem ainda a possibilidade de conservação de seu excedente. O Sul do país ainda comporta muitas áreas ociosas no período de inverno, áreas onde é cultivado milho, safra após safra, sendo esses, outros pontos favoráveis à confecção desse alimento, aumentando a lucratividade e a rotatividade da mesma. Dentre as culturas de inverno mais utilizadas para o feitio de silagem pré-secada destacam-se a aveia preta (Avena strigosa), aveia branca (Avena sativa), cevada (Hordeum vulgare), trigo (Triticum aestivum), centeio (Secale cereale), e o triticale (X Triticosecale).Palavras chave: Aveia, bromatologia, forragem conservada, proteína bruta, triticale Pre-dried silage of winter cereals in pre-flowering stage: A review ABSTRACT. The production of pre-dried silage of better cost benefit with high production, nutritional value and cost of production are fundamental for survival in the productive system. In this context, winter cereals are important because they are excellent for the in natura supply, that is, in grazing and also have the possibility of conserving their surplus. The southern part of the country still contains many idle areas in the winter period, areas where maize is grown, harvest after harvest, and these are other favorable points in the preparation of this food, increasing its profitability and its rotation. Among the winter crops most used for the pre-dried silage species are: oats (Avena strigosa), white oats (Avena sativa), barley (Hordeum vulgare), wheat (Triticum aestivum), rye (Secale cereale), and triticale (X Triticosecale).Keywords: Oat, bromatology, conserved forage, crude protein, triticale Ensilajes pre-secados de cereales de invierno en estadio de prefloración: Una revisión RESUMEN.
