Salinomycin and virginiamycin for lactating cows supplemented on pasture

Animals on pasture generally show higher feed efficiency as a result of the use of antibiotics. This study evaluated the effect of the antimicrobials salinomycin and/or virginiamycin on production and the ruminal parameters of supplemented dairy cows grazing on Panicum maximum cv. Tanzania. Twelve Holstein/Zebu multiparous cows were used, distributed in three Latin squares, one for the evaluation of ruminal parameters, and the others for production parameters. Cows on pasture were fed 50 % of their estimated intake with corn silage and concentrate supplements containing salinomycin, virginiamycin or a combination of additives, in doses of 120 and 150 mg kg−1, respectively. There were no differences in milk production and composition, energy and nitrogen balance, dry matter digestibility and feeding behavior. However, salinomycin and virginiamycin each reduced pasture and total dry matter intake by about 14 % and 10 %, with a consequent improvement in feed efficiency

Seasonal variation of the (E)-nerolidol and other volatile compounds within ten different cultivated populations of baccharis dracunculifolia DC (asteraceae)

Initially, the seeds of Baccharis dracunculifolia were collected from populations of 10 different regions, and the cultivation experiment was carried out in an experimental area of 1,800 m2 by cultivating 100 individuals of each population. The essential oil analyses were performed on both GC-FID and GC/MS, which allowed the identification of 14 compounds. The oil yield varied from 0.31% to 0.70% among populations and season. The major oxygenated sesquiterpenes in the cultivated experiment were (E)-nerolidol (32%) and spathulenol (17%). The mean concentration in the plant of (E)-nerolidol was five times higher in March (136.53 mg/100 g of plant) than it was in July (25.03 mg/100 g of plant). The mean concentration of spathulenol increased about three fold from July (16.25 mg/100 g of plant) to April (47.50 mg/100 g of plant)214308314FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP04/13005-1; 04/07331-3; 01/14219-

Relatório sobre Empreendedorismo na EUROACE 2014

As três regiões EUROACE superam o resto dos países europeus analisados no que diz respeito à educação e formação empreendedora. O Alentejo e o Centro também na transferência de R + D e no apoio ao financiamento. A Extremadura apesar de não ter uma avaliação positiva, apresenta um valor superior ao resto dos países baseados na inovação no que diz respeito às políticas e programas de governo regional para o empreendedorismo
