The relationship between the chromogen-dry matter ratio of feces voided and that of forage actually consumed was established mathematically as a result of a study of 18 pasture forage mixtures ranging in dry matter digestibility from 51.6 to 74.0%. This relationship allowed the circumvention of the manual sampling of forage, as it was found that the chromogen concentration of the forage could be predict from a knowledge of the fecal chromogen level. Data on the concentration of chromogen so estimated in the ingested forage may then be employed together with those on the chromogen concentra-
tions in the feces in the usual ratio technique for determining the digestibility of consumed
forage under conditions of grazing. An alternate procedure for the direct computation of
digestibility from the chromogen concentration of the feces was also suggested. When the
amount of dry matter voided in the feces per unit of time is known, the dry matter inatke of grazing animals may be readily computed from a knowledge of the chromogen level of the consumed forage and os the feces, or from a knowledge of the degree of indigestibility of the forage. Other applications of the principles of this method of measuring pasture forage
digestibility and intake are considered. |

‘Bartlett’ pears from different harvest dates were assessed regarding to cold storage potential and reduction of physiological disorder incidence. Three harvests, the first (HD1), second (HD2), and third (HD3), were carried out at weekly intervals. The pears were assessed after the harvest, with no exposition to the temperature conditioning, after 20, 40, 60, 80, 100 and 120 days at 0 ± 1 °C and 90 ± 5% RH and after three and six days at room temperature (20 ± 1 °C). Fruit from the early harvest (HD1) showed the smallest incidence of physiological disorder during both cold and room temperature storage. The disorder symptoms became apparent in HD1 fruit after 20 days at cold storage followed by three days at 20 °C, whereas HD2 and HD3 fruit showed the symptoms before being kept in a cold room. ‘Bartlett’ pears harvested at 70.75 N flesh firmness can be stored at 0 ± 1 °C for up to 40 days and preferably commercialized within three days, when they reach the firmness for eating. The extension of cold storage as well as the trade period can result in higher physiological disorder incidence and loss of sensorial quality. Index terms: Pyrus communis L., cold storage, flesh firmness and acceptance.

Foram realizadas três colheitas com intervalos semanais, primeira data de colheita (DC1) realizada em 25 de janeiro, segunda data de colheita (DC2) efetuada em 01 de fevereiro e terceira data de colheita (DC3) realizada em 08 de fevereiro. As peras foram avaliadas logo após a colheita, ou seja, sem o efeito de refrigeração e após 20, 40, 60, 80, 100 e 120 dias de em armazenamento refrigerado 0 ± 1 °C e umidade relativa 90 ± 5% e após três e seis dias em ambiente simulado com temperatura de 20 °C ± 1. Peras ‘Bartlett’ colhidas com firmeza de polpa de 70,75N (DC1) podem ser armazenadas em ambiente refrigerado por até 40 dias e comercializados preferencialmente até três dias.
