          Abstract

          ABSTRACT This study aimed to evaluate total mixed ration silages with sugarcane and the additives microbial inoculant and chitosan. Thirty mini-silos were used in a completely randomized design, with three treatments and ten replications. Silages were composed of sugarcane mixed with corn bran, whole soybean, urea, and mineral mixtures at a 50:50 roughage to concentrate ratio. Treatments consisted of control silage, microbial additive (Lactobacillus plantarum + Pediococcus acidilactici, 4 g/t of KeraSil, Kera Nutrição Animal), and chitosan (10 g/kg of natural matter). Silages were evaluated for fermentation and microbiological profile, fermentation losses, aerobic stability, chemical-bromatological composition, intake, and digestibility. Fermentation profile showed no significant difference between treatments for pH values, with a mean value of 4.79. Production of acetic and propionic acids showed no difference between treatments, with mean values of 7.34 and 0.053 mmol/kg DM, respectively. Dry matter, organic matter, and crude protein intake of the total mixed ration silage differed statistically from the other treatments (P<0.05), but fresh sugarcane and sugarcane silage intake did not differ from each other (P>0.05). Digestibility values of DM, OM, and NDF were higher in the total mixed ration silage (P<0.05), while sugarcane silage and fresh sugarcane showed no difference from each other (P>0.05). Total mixed ration silage increased nutrient intake and digestibility, with a better fermentation pattern when added with the microbial inoculant.

          RESUMO O objetivo foi avaliar as silagens de ração total com cana de açúcar e aditivos inoculante microbiano e quitosana. Foram utilizados trinta mini-silos utilizando o delineamento inteiramente casualizado, com três tratamentos e dez repetições. As silagens foram compostas por cana-de-açúcar misturada com farelo de milho, soja integral, uréia e misturas minerais na proporção de 50:50. Os tratamentos foram: silagem controle, aditivo microbiano (Lactobacillus plantarum + Pediococcus acidilactici, 4 g/t de KeraSil, Kera Nutrição Animal) e quitosana (10 g/kg da matéria natural). As silagens foram avaliadas quanto à fermentação e perfil microbiológico, perdas de fermentação, estabilidade aeróbica, composição químico-bromatológica, consumo e digestibilidade. O perfil de fermentação não mostrou diferença significativa entre tratamentos para os valores de pH, com um valor médio de 4,79. A produção de ácidos acéticos e propiônicos não mostrou diferença entre os tratamentos, com valores médios de 7,34 e 0,053 mmol/kg DM, respectivamente. A matéria seca, a matéria orgânica e a ingestão de proteína bruta da mistura total de ração silagem diferiram estatisticamente dos outros tratamentos (P<0,05), mas a ingestão de cana-de-açúcar fresca e de silagem de cana-de-açúcar não diferiram uma da outra (P>0,05). Os valores de digestibilidade de DM, OM e NDF foram maiores na silagem de ração mista total (P<0,05), enquanto a silagem de cana de açúcar e a cana de açúcar fresca não mostraram diferença entre si (P>0,05). A silagem de ração mista total aumentou a ingestão de nutrientes e a digestibilidade, com um melhor padrão de fermentação quando adicionado o inoculante microbiano.

          Nutritional Ecology of the Ruminant

          This monumental text-reference places in clear persepctive the importance of nutritional assessments to the ecology and biology of ruminants and other nonruminant herbivorous mammals. Now extensively revised and significantly expanded, it reflects the changes and growth in ruminant nutrition and related ecology since 1982. Among the subjects Peter J. Van Soest covers are nutritional constraints, mineral nutrition, rumen fermentation, microbial ecology, utilization of fibrous carbohydrates, application of ruminant precepts to fermentive digestion in nonruminants, as well as taxonomy, evolution, nonruminant competitors, gastrointestinal anatomies, feeding behavior, and problems fo animal size. He also discusses methods of evaluation, nutritive value, physical struture and chemical composition of feeds, forages, and broses, the effects of lignification, and ecology of plant self-protection, in addition to metabolism of energy, protein, lipids, control of feed intake, mathematical models of animal function, digestive flow, and net energy. Van Soest has introduced a number of changes in this edition, including new illustrations and tables. He places nutritional studies in historical context to show not only the effectiveness of nutritional approaches but also why nutrition is of fundamental importance to issues of world conservation. He has extended precepts of ruminant nutritional ecology to such distant adaptations as the giant panda and streamlined conceptual issues in a clearer logical progression, with emphasis on mechanistic causal interrelationships. Peter J. Van Soest is Professor of Animal Nutrition in the Department of Animal Science and the Division of Nutritional Sciences at the New York State College of Agriculture and Life Sciences, Cornell University.
