1. ADDITION OF BOILER CHARCOAL WASTE TO COMPOST FOR USE AS SUBSTRATE FOR VEGETABLE SEEDLINGS
ABSTRACT The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. T

2. EXTRACTION CAPACITY OF GRASSES GROWN IN CONSTRUCTED WETLAND SYSTEMS USING DIFFERENT ARRANGEMENTS AND SUBSTRATES
ABSTRACT Constructed wetland systems have been used to treat different wastewater; among their essential components are the cultivated plant species and type of substrate used to fill them. The choice of plant species and type of substrate are important for the good system performance in wastewater treatment. This study aimed to evaluate the extraction capac

3. Dynamics of forage accumulation in Elephant grass subjected to rotational grazing intensities
We assessed the accumulation dynamics of forage and its components in Elephant grass cv. Napier (Pennisetum purpureum Schum.) that were subjected to three post-grazing height treatments (30, 50, and 70 cm) from February through May 2009 (experiment one) and December 2009 through May 2010 (experiment two). In experiment one, the grazing events started when th

4. Performance of Braford steers grazing on cultivated pastures and fed or not fed an energy supplement
This experiment evaluated the performance of 84 Braford steers grazing on summer and winter cultivated pastures fed or not fed an energy-protein supplement. Steers were 10 months old and weighed, on average, 165 kg at the beginning of the trial. Steers grazed on cultivated winter pasture, consisting of black oats (Avena strigosa) and ryegrass (Lolium multifl

5. Caracterização microbiológica, parâmetros fermentativos e estabilidade aeróbia em silagens de forragens tropicais com aditivos microbianos / Microbiologic characterization, fermentative parameters and aerobic stability of tropical forage silages with microbial additives
Foram realizados dois experimentos para avaliação de aditivos microbianos na ensilagem de forragens tropicais. No primeiro experimento avaliou-se o efeito de doses crescentes de Lactobacillus buchneri, em diferentes tempos de armazenamento, sobre o valor nutritivo, perfil fermentativo e estabilidade aeróbia de silagens de milho. No segundo experimento ava

6. Nutritional value of some feedstuffs used in the diet of captive capybaras
Five pen-raised adult female capybaras were used in five digestibility trials in a Latin square design, to determine, for capybaras, the nutritional values of Cameroon grass (Pennisetum purpureum cv. Cameroon); Napier grass (P. purpureum cv. Napier); corn grain; cassava hay, comprising leaves and stems; and palm kernel (Elaeis guineensis) cake. These feedstu

7. Dynamics of production and forage utilization on elephant grass pastures managed with different post-grazing heights
This study was conducted to evaluate the daily production of forage and its morphological components, as well as the potential of forage utilization in pastures of Pennisetum purpureum cv. Napier managed with three post-grazing heights (30, 50 and 70 cm). Two experiments were carried out: one from February to May 2009 and another from December 2009 to May 20

8. Effect of different substrates on composting of poultry litter
The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The treatments were established according to material used as substrate for broiler litter: treatment 1 - rice husks; 2 - sugar cane bagasse; 3 - w

9. Selecting the most adequate bedding material for broiler production in Brazil
Broiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and regions within a same country. This study aimed at applying a multiple criteria analysis approach for the selection of the most appropriate b

10. Litter materials and the incidence of carcass lesions in broilers chickens
The aim of this study was to evaluate the effects of different litter materials on litter compaction, broiler feathering and the incidence of carcass lesions. In the experiment, 3240 one-day-old Ross® chicks were selected by sex and distributed according to a completely randomized experimental design in a 2 x 6 factorial arrangement (two sex and six litter

11. Evaluation of the Cornell Net Carbohydrate and Protein System model on the prediction of dry matter intake and milk production of grazing crossbred cows
The Cornel Net Carbohydrate and Protein System model version 5.0 was assessed as for its prediction of dry matter intake and milk production of grazing lactating Holstein × Zebu cows. Eight lactating cows grazing elephant grass (Pennisetum purpureum, Schum., cv. Napier) were used in two experiments of 30 days each. The experimental design was of randomized

12. Estratégias de manejo do capim-elefante cv. Napier sob pastejo rotativo / Strategies for management of elephant grass cv. Napier under rotational grazing
As estratégias de manejo do pastejo devem explorar e utilizar recursos adaptativos e estabelecer amplitudes ótimas de manejo para as espécies forrageiras, já que estas sofrem constantemente a interferência dos animais que as pastejam e de fatores do meio necessitando de mecanismos de adaptação para conseguir persistir no sistema. Foram objetivos deste
