1. Effects of antibiotic growth promoters and concentrate on intake, digestibility, degradability, and ruminal variables in beef steers
RESUMO O objetivo foi avaliar a adição de antibióticos promotores de crescimento ao concentrado sobre o consumo, digestibilidade, degradabilidade in situ e variáveis ruminais de novilhos. Quatro novilhos em um delineamento quadrado latino foram alimentados com feno (ad libitum), concentrado [10g kg-1 do peso corporal (PC)] e mistura mineral (0,272g kg-1

2. Potential and restrictions of Poincianella pyramidalis (Tul.) L. P. Queiroz as native forage in the Brazilian semi-arid region
ABSTRACT. Poincianella pyramidalis (catingueira) is a endemic plant of the Caatinga, selected by animals grazing on native pasture. With the aim of evaluating characteristics indicative of its nutritional quality, 10 plants were selected and identified, sampled at five different ages, were used to determine dry matter (DM), crude protein (CP), neutral deterg

3. Utilization of a novel feedstuff: effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (Robinia pseudoacacia) silage
RESUMO: Este estudo foi conduzido para avaliar os efeitos de aditivos nas características de fermentação, composição química e digestibilidade in vitro do gafanhoto preto tetraplóide (TBL). A silagem de folhas TBL não foi tratada (controle) ou foi tratada com 1 × 106 ufc / g FM Lactobacillus plantarum (L), 1% glicose (G), 3% melaço (M), uma combin

4. Mechanical and bioactivity assessment of wollastonite/PVA composite synthesized from bentonite clay
Resumo Os compósitos de vidro/polímero podem imitar a estrutura natural do osso possuindo uma configuração fibra-matriz que proporciona propriedades físicas e biológicas apropriadas. As cerâmicas de wollastonita são conhecidas por suas bioatividade e biocompatibilidade promissoras quando aplicadas na regeneração óssea. O álcool polivinílico (PVA

5. USE OF VIRGINIAMYCIN AND SALINOMYCIN IN THE DIET OF BEEF CATTLE REARED UNDER GRAZING DURING THE RAINY SEASON: PERFORMANCE AND RUMINAL METABOLISM
Resumo O rúmen é o órgão mais estudado no que se refere à interação simbiótica entre hospedeiro e a microbiota do trato digestivo dos ruminantes. Assim, objetivou-se avaliar os efeitos da inclusão de virginiamicina e de salinomicina ao suplemento para bovinos de corte com dieta de gramínea tropical no período das águas. Foram constituídos três

6. Perspectives of Dendrimer-based Nanoparticles in Cancer Therapy
Abstract Currently, cancer is the second most common cause of death in the United States, exceeded only by heart disease. Chemotherapy traditionally suffers from a non-specific distribution, with only a small fraction of the drug reaching the tumor, in this sense, the use of dendrimers incorporating drugs non-covalently encapsulated inside the dendrimer or c

7. In vitro fermentation characteristics of ruminant diets using ethanol extract of brown propolis as a nutritional additive
ABSTRACT The addition of levels of ethanol extract of brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative in vitro gas production by nonlinear (dual pool logistic and exponential) models. A total of 35 g of crude propolis were extracted in 65 mL of cereal alcohol (95% ethanol). In a completely randomized factor

8. Development of a novel compound microbial agent for degradation of kitchen waste
Abstract Large quantities of kitchen waste are produced in modern society and its disposal poses serious environmental and social problems. The aim of this study was to isolate degradative strains from kitchen waste and to develop a novel and effective microbial agent. One hundred and four strains were isolated from kitchen waste and the 84 dominant strains

9. Additives on in vitro ruminal fermentation characteristics of rice straw
ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO2 production, and volatile fatty acid concentration of rice st

10. Degradability and kinetics of fibrous particles in cattle fed diets based on corn silage and concentrates with or without addition of lipids
ABSTRACT Eight rumen-cannulated steers were assigned to two 4 × 4 balanced Latin squares to evaluate degradability and kinetics of fiber particles from diets based on corn silage and supplements with or without addition of lipids. Dietary treatments were: only corn silage (T1), corn silage plus concentrate with no added lipids (T2), corn silage plus concent

11. Performance and metabolite profile of dairy cows fed tropical grasses and concentrates containing crude protein with low or high degradability
ABSTRACT Ten Holstein-Zebu crossbred cows distributed into two simultaneous Latin squares (5 × 5) as a 2 × 2 factorial arrangement formed by chopped sugarcane or elephant grass silage, both with high or low protein degradability supplements and a corn silage as a control treatment, were compared using orthogonal contrasts. The studied variables were the pe

12. Effects of lines and inoculants on nutritive value and production costs of triticale silages
ABSTRACT The current study was undertaken to investigate the ensilage characteristics in triticale lines treated by inoculants and their interaction on fermentation metabolites and rumen degradability. Costs were estimated for growing and feeding whole-crop triticale lines for animal production. Triticale hybrids were harvested at the dough stage of maturity
