“…In the present in situ study, the potential degradability of NDF by L. edodes (27.2%) and P. chrysosporium (32.0%) were significantly higher than that in the control (19.3%), which resulted in higher ruminal ED of NDF in the two treatments and supported this assumption. Similar to our results, some studies also observed an increase in in vitro NDF digestibility, as with IVOMD or IVDMD, from treatment of lignocellulose with different white-rot fungi (Karunanandaa and Varga 1996;Okano et al 2006). Secondly, lower NDF content may have resulted in higher IVOMD in L. edodes and P. chrysosporium treatments.…”

The use of rape straw in ruminant production is limited by its high lignin content and low ruminal degradability. White rot fungi are the most efficient known degraders of lignin. Four white rot fungi were investigated for their potential to degrade lignin and improve rumen fermentation of rape straw. Solid state fermentation of the straw was carried out for 0 to 30 days to determine changes in chemical composition and in vitro rumen fermentation. Results showed that Phanerochaete chrysosporium and Lentinula edodes degraded about 45% of lignin and enhanced the in vitro organic matter digestibility (IVOMD) and volatile fatty acid production; however, about 55% of the cellulose was lost after 30 days of incubation. Ceriporiopsis subvermispora and Phlebia acerina degraded a fraction (< 30%) of lignin and cellulose, but inhibited ruminal fermentation. Fungal incubation increased the chitin content of rape straw. Regression analysis showed that the IVOMD increase depended on the combined action of neutral detergent fiber loss and chitin content increase in rape straw. This study indicates that considerations of the conversion of rape straw into ruminant feed with white-rot fungi should take into account the degradation of lignin, fiber loss, and the chitin produced along with the growth of fungi.

“…The average in vitro digestibility of this study was similar to that obtained by Okano et al (2006) and Carvalho et al (2010). The NDF/Brix ratio had an average value of 3.3; this value can be accepted as adequate for this ratio between the analyzed varieties to avoid the higher NDF content of certain varieties limiting sugar intake by the animal, which is the component that provides the largest portion of digestible energy to the animal.…”

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.

Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R 1 control (0% sago flour), R 2 (5% sago flour), R 3 (10% sago flour), R 4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P<0, 05) on crude fiber and ash contents. However, there were not significantly difference (P>0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse. Keterbatasan sumber bahan pakan hijauan bagi ternak ruminansia akibat perubahan fungsi lahan perlu dicari sumber alternatif pengganti hijauan. Potensi bahan pakan ternak ternak ruminansia sebagai penganti hijauan sangat besar di Provinsi Aceh (Samadi et al., 2010). Salah satu bahan pakan alternatif sumber serat pengganti hijauan adalah hasil samping industri pertanian seperti ampas tebu. Saat ini pemanfaatan ampas tebu sebagai pakan ternak belum maksimal, karena rendahnya kualitas ampas tebu sehingga kecernaannya rendah. Menurut Pandey et al. (2000) ampas tebu mengandung lebih kurang 50% selulosa, 25 % hemiselulosa dan 25 %
