Rhinus evelinae sp.n., uma nova espécie de Bulimulidae (Gastropoda, Sigmurethra), do sudeste brasileiro

Com base em caracteres conquiológicos e anatômicos, é descrita uma nova espécie do gênero Rhinus Albers, 1860, R. evelinae sp. n., procedente da Região Sudeste do Brasil. Conquiologicamente, a nova espécie é comparada com R. obeliscus (Haas, 1936) e com R. pubescens (Moricand, 1846). Seus dados anatômicos são relacionados aos únicos existentes na literatura (Breure, 1978, 1979), envolvendo R. ciliatus (Gould, 1846)

Voluntary Intake of Tanzania Grass (\u3ci\u3ePanicum maximum\u3c/i\u3e) under Rotational Grazing by Lactating Cows

The study was conducted at Nucleo de Pesquisas Zootecnicas Nordeste of the Instituto de Zootecnia, Ribeirão Preto, SP, in a rotational grazing area of Tanzania grass (Panicum maximum), to estimate the dry matter intake by lactanting cows. The estimation of dry matter intake was calculated from the feces production estimated using extrusa Chromium-mordent and the in vitro digestibility of diet. The three treatments were crossbreed cows fed 3 kg.day-1 of concentrate, crossbred cows without concentrate suplementation and pure Gir cows also without concentrate supplementation. The milk production was 11.98, 6.53 and 5.46 kg per cow per day, the grass intake was 8.26 ± 5.66, 11.01 ± 5.37 and 9.55 ± 2.31 kg of dry matter per day or 2.15%, 2.37% and 2.34% of live weight for the three experimental groups respectively. The milk production was higher (P\u3c 0.01) for cows fed with concentrate. No difference was found for dry matter intake
