“…Lignin content remained the same among varieties (Table 3). Similar results were described by Oliveira et al (2012), when analyzing NDF, ADF and lignin contents in four sugarcane varieties (RB72454, RB867515, RB855536 and IAC86-2480). The values were not statistically different and average levels were similar to this experiment.…”

Brazilian semi-arid soils can be dystrophic and often occur in areas with high agricultural potential. Gypsum application improves chemical and physical soil conditions, favoring root system development of plants and can improve sugarcane production for energy production, as a strategy for sustainable development, avoiding native vegetation destruction in semi-arid regions. This study aimed to analyze the impact of gypsum application on the agro-energy potential of three sugarcane varieties, through MS production, moisture, neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin, ash and gross calorific value (GCV). The experimental design consisted of 3 (varieties) x 2 (with and without gypsum) over two sugarcane growing periods in a completely randomized block design with four replications. The application of gypsum did not affect the tested agro-energy variables. GCV ranged around 17 MJ kg -1 , confirming the suitability of the varieties for bioenergy use in semi-arid regions, but there were no significant differences between sugarcane varieties.

“…There was not a significant difference (P>0.05) for the neutral detergent fiber and acid detergent fiber contents between the studied varieties, with values similar to those observed by Oliveira et al (2012), who obtained NDF values that varied from 35 to 63% and ADF values that varied from 21 to 36%.

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.

“…This lack of difference is due to the balance of the diet, since there were different proportions of forage and concentrate to balance the energy, as can be observed with the NDFcp contents of the diets in Table 2. The values found for CNDFcp in %BW of 1.09%BW are below values found in the literature, in which, Oliveira et al (2012) reported in a literature review the overall average for the intake of 1.6% NDF in relation to the body weight.…”

This study aimed to evaluate the inclusion of castor bean meal in the diet for lactating cows on Bracharia brizhanta pasture and its implications for nutritional and productive parameters. Eight crossbred cows were distributed in two 4 x 4 Latin squares, with four (0%; 3.33%; 6.66% and 10%) inclusion levels of castor bean meal in the total diet. The experiment consisted of four experimental periods of 21 days each. The digestibility and dry matter intake were estimated from fecal output, checked with the aid of external (chromium oxide) and internal (iNDF) indicators. Urine and milk were collected to determine the nitrogen balance and microbial protein production. The inclusion of different levels of castor bean meal in the diet for lactating cows did not affect the intake of dry matter and nutrients, and the same lack of effect was found for the digestibility of dry matter and total digestible nutrients, variation in body weight, milk production, chemical composition of milk, microbial production and nitrogen balance. The inclusion of up to 10% castor bean meal in the total diet did not influence productive parameters evaluated, and the use was conditioned to the price of castor bean meal. Key words: Nitrogen balance. Consumption. Milk production. Microbial protein. ResumoObjetivou-se avaliar a inclusão de farelo de mamona na alimentação de vacas lactantes em pastejo de Bracharia brizhanta e suas implicações nos parâmetros nutricionais e produtivos. Foram utilizadas oito vacas mestiças distribuídas em dois quadrados latinos 4 x 4, com quatro níveis de inclusão de farelo de mamona na ração total; 0%; 3,33%; 6,66% e 10%. O experimento foi constituído de quatro períodos experimentais, com duração de 21 dias cada. A digestibilidade e o consumo de matéria seca foram estimados a partir da produção fecal, verificada com o auxílio de indicadores externo (oxido de cromo) e interno (FDNi). Foi feita a coleta de urina e leite para determinação do balanço de nitrogênio
