“…However, the high dry matter yield per unit area is the main factor that still encourages its use (SIQUEIRA et al, 2012). The whole maize plant also has a high dry matter production potential per unit area, but it has a nutritional value that is higher than the cane (ZEOULA et al, 2003) (Table 5), thus giving it the potential to feed dairy cattle.…”

The dairy industry is characterised by a wide diversity of production systems. In this diverse environment, some of the difficulties can be minimised through the grouping of production units through the study of typology. The objective was to characterise the systems of milk production from West Parana State by considering production rates, area, power, facilities, and marketing of milk. To this end, 735 semistructured interviews with dairy farmers were performed by using a questionnaire for management practices and feed that is used on the farms. To obtain the explanatory variables used for principal component analysis (PCA) and hierarchical cluster analysis (HCA), a homogeneous division of 735 farmers in five groups was used. Ten per cent of producers were randomly selected for the performance of field visits to the properties, where a new questionnaire was applied with specific points regarding feeding management on the property, and feed was collected to determine its composition. The collected data were tabulated and feed was ranked based on the classification proposed by the NRC (2001). Analyses of feed were carried out in the Laboratory of Animal Nutrition of Unioeste. The West Parana State has five groups of dairy production systems. There is great variability in the fresh forages that are used, but maize silage is the main forage utilised for fermented feed, and concentrate supplementation is adopted by more than 60% of farms during both seasons. Changes in the levels of feed components are high among systems. Key words: Animal feed. Characterisation of production. Composition of foods. Dairy farming. ResumoA pecuária leiteira é caracterizada por ampla diversidade de sistemas de produção. Nesse ambiente diverso, algumas das dificuldades podem ser minimizadas por meio do agrupamento das unidades de produção através do estudo da tipologia. Objetivou-se caracterizar os sistemas de produção de leite do Oeste do Estado do Paraná considerando os índices de produção, área, alimentação, instalações e comercialização do leite. Para tal, foram realizadas 735 entrevistas semiestruturadas, com produtores de leite, utilizando um questionário guia referente a práticas de manejo e dos alimentos utilizados nas propriedades. Para a obtenção das variáveis explicativas usou-se a análise de componentes principais (ACP) e análise de clusters hierárquicos (CHA), obtendo-se a divisão homogênea dos 735 produtores em cinco grupos. Destes foram selecionados ao acaso 10% dos produtores cada para a realização das visitas a campo nas propriedades, aplicando-se um novo questionário que contemplava pontos específicos do manejo alimentar utilizado na propriedade, bem como a coleta de alimentos para determinação da sua composição. Os dados coletados foram tabulados e os alimentos classificados com base na classificação dos alimentos proposta pelo NRC (2001). As análises dos alimentos foram realizadas no Laboratório de Nutrição Animal da Unioeste. O Oeste do Estado do Paraná possui cinco grupos de sistemas de produção leiteira. ...

“…Sugar cane has a low nutritional value (SIQUEIRA et al, 2012) (Table 5), which limits its use in dairy herds, and is only recommended for average, low production animals. However, the high dry matter yield per unit area is the main factor that still encourages its use (SIQUEIRA et al, 2012).…”

“…The reduction of the NDF:Pol ratio contributed to increasing digestibility values, leading to greater energy intake (Siqueira et al, 2012). According to Mello et al (2006), this parameter is important in the choice of varieties for ruminant feeding, as its average is lower than 3.03%.…”

-This study aimed to evaluate the biometric and chemical characteristics of five sugarcane varieties (RB 863129, RB 867515, RB 92579, RB 943365, and RB 98710) grown in a semi-arid climate for use as forage. The experiment was designed as randomized blocks, in a 5 × 2 factorial arrangement (five sugarcane varieties and two evaluation times, 407 and 483 days). Response variables included dry matter productivity, morphological characteristics, chemical composition, digestibility, and ratios among neutral detergent fiber (NDF), Brix, and Pol. For the biometric analyses, there was an interaction effect between the evaluated varieties and harvest times on the variables fresh matter yield, uncovered internodes, and stalk density (MID -middle internode density). Regarding stalk density (MID), at 407 days, there was no significant difference among the varieties (1.19 g cm −3). For the fractionated parts, there was an effect of harvest time on the amount of fresh matter and dry matter of tops produced, which was highest at 407 days of age. A significant difference was detected among the varieties for contents of dry matter and total digestible nutrients. The variable in vitro neutral detergent fiber digestibility was influenced by the time, decreasing by 53.62 g kg −1 at 483 days. In the analysis of Brix and Pol yields per hectare, it was observed that variables ton of Brix per hectare and ton of sucrose per hectare averaged 15.12 and 10.14 t ha −1 , respectively, and the NDF:Brix and NDF:Pol ratios were higher for variety RB 863129, with 2.93 and 3.68, respectively. Variety RB 867515 is suggested for forage production in semi-arid conditions, as it is best adapted to the local soil-climatic conditions and to the water deficit, especially at 407 days.

“…The latter factor confers sugarcane an advantage as a forage plant because tropical forages suffer quantitative and qualitative losses during the dry season, which is when sugarcane contains the highest energy content in the form of sucrose (ABRANCHES; BOLONHEZI, 2011). Various studies have been performed on the use of sugarcane as animal feed; however, the nutritional value of this crop has been the object of much discussion, primarily with regard to identifying varieties with more suitable characteristics for forage production and with regard to management (SIQUEIRA et al, 2012). The hypothesis postulated by Boin et al (1987), i.e., that the best forage sugarcane varieties are those that exhibit a high proportion of leaves and stems relative to the total green matter, is no longer supported because the green matter yield and nutritional value must also be considered together with the sugar content and neutral detergent fiber fraction (NDF).…”

This study evaluated the nutritional value of sugarcane varieties in relation to nitrogen fertilization. The varieties studied were RB 863129, RB 867515, and RB 92579, and nitrogen fertilizer was applied at doses of 0, 60, 80, 120, and 140 kg N ha -1 . The experiment was divided into two stages: i) Year I -plant cane, when the yield and nutritional quality of the three sugarcane varieties were evaluated; ii) Years II and III, when and the effect of nitrogen fertilization on the nutritional quality of the first and second ratoon crops of the same varieties was evaluated. In plant cane the yield (t ha -1 ) and DM (dry matter) and CP (crude protein) contents were higher for the RB 863129 variety. There was no difference between the varieties regarding their NDF (neutral detergent fiber) and ADF (acid detergent fiber) contents and IVDMD (in vitro dry matter digestibility). In the first and second ratoon crops, there was a difference between the varieties and fertilizer doses for the evaluated parameters, with the exception of the DM content and IVDMD, which were influenced by the varieties, doses of N, and cutting years. The RB 92579 variety showed the best yield of the two ratoon crops (131 t ha -1 of stems) and the best nutritional parameters (26% ADF, 41% NDF, 2.4% CP, and 69.4% IVDMD). The sugarcane yield and its nutritional quality can be influenced by the cutting year and nitrogen fertilization management system and by the variety type. Key words: In vitro digestibility.

As variedades estudadas foram RB 863129, RB 867515 e RB 92579, e as doses nitrogenadas 0, 60, 80, 120 e 140 kg N ha -1 . O experimento foi dividido em duas etapas: i) Ano I -Cana-planta: avaliou-se a produtividade e qualidade nutricional de três variedades de cana-de-açúcar; ii) Anos II e III: avaliou-se a influência da adubação nitrogenada na qualidade nutricional da primeira e segunda soca das mesmas variedades. Na cana-planta foram determinados o teor de Brix e a relação FDN/Brix. Para a cana-planta, a produtividade (t ha -1 ) e os teores de MS e PB, foram superiores (P < 0.05) para a variedade RB 863129. Não houve diferença (P < 0,05) entre as variedades para os teores de FDN e FDA e para a DIVMS. Na primeira e segunda soqueira houve diferença (P < 0,05) entre variedades e doses de adubação para os parâmetros avaliados, com exceção do teor de MS e digestibilidade in vitro, que foram influenciados (P < 0,05) pelas variedades, doses de N e anos de corte. A variedade RB 92579 apresentou nas duas soqueiras a melhor produtividade (131 t ha -1 de colmos), aliada aos melhores parâmetros nutricionais (FDA 26%, FDN 41%, PB 2,4% e DIVMS 69,4%). A produtividade da cana-de-açúcar, assim com a sua qualidade nutricional, pode ser influenciada pelo manejo da adubação nitrogenada, ano de corte e pela variedade.
