La introducción de nuevos recursos genéticos es esencial en la evolución de la agricultura destinada a la producción de materia prima de alta calidad. La evaluación de nuevo germoplasma, con el objetivo de su difusión comercial o incorporación a programas de mejoramiento, se realiza a través de ensayos comparativos de rendimiento en diferentes ambientes. Las forrajeras anuales de invierno son casi insustituibles para mantener la cadena forrajera en la región pampeana subhúmeda seca y semiárida. En la actualidad tanto triticales como tricepiros son alternativas muy promisorias para su utilización como doble propósito, así como para explorar la posibilidad de producir harinas diferenciadas para uso en la industria de la alimentación humana. En el país, los triticales se han difundido para pastoreo y se requiere de nuevos cultivares. Los tricepiros se trabajan exclusivamente en la Argentina y es necesario desarrollar germoplasma. Se planea identificar germoplasma superior mediante selección en introducciones y cruzamientos propios, ensayos comparativos de pasto y grano, estudiar la estabilidad citológica mediante análisis cromosómicos y genómicos y caracterizar líneas avanzadas por descriptores morfológicos.

Brazil is the world's second largest producer of cassava, which most of the production is used to make flour and starch, generating large amounts of waste, cassava. In general, this waste is disposed of directly into the soil and waterways, causing serious environmental impacts. In view of this, the aim of this work was to evaluate the use of cassava wastewater water (cassava) as organic fertilizer in Brachiaria brizantha pasture. Marandu. The experiment was conducted at the Campus Macaíba the Federal University of Rio Grande do Norte. The treatments were increasing rates of cassava, applied to the soil as organic fertilizer. The experimental design was a randomized block design with six treatments and four replications. The treatments consist of cassava doses (0, 15, 30, 60 and 120 m³ ha- 1 ) and a treatment with mineral fertilizer (AM) in the form of NPK (140: 30: 120 kg ha-1 ). Three cuts with an interval of 60 days were carried out. The variables evaluated were: plant height; accumulation of morphological components of fodder; Trapping Light (IL); Leaf Area Index (LAI); Total chlorophyll (CT); Feature Production Seca (PMS). The dry matter production at a dose of 120 m³ha-1 had a quantitative increase, with a total production in 2796 kg ha-1 DM in the second cut, providing an increase of 493% compared to control, and the residual effect observed in the third cut caused a 100% increase compared to 0 m³ ha-1 . Comparing the PMS obtained with the use of AM and other treatments it was observed that it was the second cut equivalent to a dose of 120 m³ ha-1 and the third equivalence has been cut at doses 60 and 120 m³ha-1. For the variables plant height, IL, IAF, CT and leaves Mass adding cassava in the soil promoted a positive linear increase for the three cuts. However, with the AM the IAF was superior to the other treatments. The thatched mass reached its highest production (838 kg ha-1 DM) in the second cut when using a dose of 120 m³ha-1 . In dead material mass in the second and third sections, there was increased linearly increased total of 322 and 452% respectively, compared to a dose of 0 m³ha-1 . The use of cassava showed herbicidal effect for the variable mass of the undesirable negative linear response resulting in decreasing the amount of residue with increasing doses. Manipueira can be used as organic fertilizer in Brachiaria brizantha cv. Marandu for improvements in the productive characteristics, as promoted significant increases in 8 most of the variables studied, especially at a dose of 120 m³ha-1 . This benefits the environment by being alternative for disposal of cassava.

The objective of this study was to evaluate the productive performance, metabolic and feeding behavior of sheep after ninety days deferred pasture at different heights. The experiment was conducted at Capim Branco experimental farm of the Universidade Federal de Uberlândia. During the period of 90 days, from June to September 2013, forty-eight crossbred lambs Santa Inês x Dorper, divided into groups of four animals, occupied twelve pickets deferred pasture with four initial heights (15 cm, 25 cm, 35 cm and 45 cm). During this period we evaluated the structural characteristics of pasture. For confinement, from September to December 2013, 32 of these animals were used (16 males and 16 females), divided into four bays, separated as pasture were using. The consumption was assessed daily, while biometric measurements were made every 21 days. In relation to gender, there were differences in average daily gain weight. Reviews of feeding behavior occurred at the beginning, middle and end of the experiment for 24 hours. The rumination and leisure activities do not present statistical differences, both initial height of pasture and by period. The time spent on intake was higher during the daytime both treatments starting height as the experimental periods, however, rumination activity was more intense at night. Blood glucose was achieved in five periods of the day, while other metabolites have been obtained with a collection made fortnightly. The different initial heights not promoted effects on blood glucose. The harvesting times were not affected. However, there was a reduction of basal blood glucose of animals throughout the experimental period. There was a significant interaction between the initial pasture heights and periods of evaluation of basal glucose. Cholesterol and triglyceride levels were below recommended levels, however the final phase of confinement cholesterol level increased significantly. The values of VLDL and GGT were above the reference range. FA and AST showed average values within the recommended values. Total protein was influenced by different initial heights of pasture. The creatinine and albumin had values below the recommended range. Moreover, the albumin decreased during the confinement time. Uric acid showed close to the recommended maximum. There was stabilization of compensatory growth, with modification of consumption and weight gain at 45 days of experiment.

The proper use of management strategies, such as grazing intensity and nitrogen fertilization are primordial to the success of integrated crop-livestock system. Several studies have demonstrated the influence of grazing intensity and nitrogen fertilization on dynamics of forage production and nutrient cycling. However, most this researches studying these strategies in isolation and little is known about the interaction of these factors in the management of an integrated crop-livestock system. In this context, the aim of this study is to determine the best management strategy involving sward height and nitrogen fertilization, permitting greater forage production and improved efficiency in the use of nitrogen soil by a black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture in integrated crop-livestock system. The experiment was realized in Abelardo Luz – SC, in an area of 14 ha, where has been conducted an experiment in long term with integrated crop-livestock system under no-tillage since 2012. The experimental design is a randomized block design with three replications in a factorial design (2x2), the first factor was the grazing intensity (high and low), characterized by two sward height management (10 and 25 cm), and the second included the time factor application of N in the system: N applied on pasture (N-pasture) and N applied on the culture of grain (N-grain), at dose of 200 kg N ha stocking and variable stocking rate. The previous crop to pasture was corn. The nitrogen fertilization of pasture increased tiller density, forage density, participation of ryegrass ‘Barjumbo’ and percentage of ryegrass leaves in forage mass. Forage mass was less at low sward height on average, however the percentage of ryegrass ‘Barjumbo’ and rye leaves was greater and dead material was lower in this treatment. With nitrogen fertilization of pasture it was possible to double the amount of forage accumulated in periods with further development of ryegrass, furthermore, the total production of DM was increased in 38.4% and the shoot N concentration in 28.6%. When the nitrogen fertilization is applied in pasture, it is possible to keep black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture with an average sward height of 11 cm. The residual effect of N applied at corn was not sufficient to meet the nutritional needs of pasture and the forage production was affected by periods with N deficiency, while a single application of 200 kg N ha was sufficient to meet the N requirements throughout the forage accumulation period. The black oat ‘BRS 139’ plus ryegrass ‘Barjumbo’ pasture is efficient in use and recovery of the nitrogen applied in both treatments of sward height.
