Data from five experiments with dairy cows where feed was restricted to 0, 40, and 50 % of the ad libitum amount, with 259 observations, were subjected to multivariate analyses to determine the effects of severity and duration of feed restriction on production, physical-chemical characteristics, ethanol stability, and somatic cell score of milk. A negative relationship was seen between the severity and duration of feed restriction with milk production, lactose content, titratable acidity, and milk stability to the ethanol test. The milk stability to the ethanol test, protein content, milk yield, and somatic cells score were the most important attributes retained by the discriminant analysis. Milk stability to the ethanol test, live weight, days in restriction, and pH were the most important characteristics explaining the variance within the different levels of feed restriction. Milk production and ethanol stability were significantly lower in both levels of feed restriction compared with the group fed ad libitum. When feed restriction was followed by refeeding, the difference observed in ethanol stability was the first discriminant variable, followed by the difference in unstable milk frequency and titratable acidity. Increments in the severity and duration of feed restriction negatively affect milk production and milk ethanol stability. |

Mangabeira (Hancornia speciosa) is a native fruit tree found mainly in the Cerrado biome and shows great economic potential due to its multiple uses; the fruits are used in agriculture, are important as a food resource, and can be consumed in natura or processed. Due to a reduction in the area of ecosystems where it occurs, mangabeira is threatened by genetic erosion in Brazil. The characterization of the genetic diversity of plants can provide the basis for strategies to protect and conserve endangered populations, like mangabeira. This study aimed to compare eight DNA extraction methods in mangabeira because the key to success is the use of a pure genomic DNA for the characterization of genetic diversity in molecular biology techniques. The quality and concentration of DNA were revealed by agarose gel electrophoresis. Polymerase chain reaction amplifications were successfully by extractions using two commercial purification kits and by the method proposed by Khanuja et al. (1999), which produced sufficient genomic DNA of good quality from leaves of H. speciosa to perform techniques involving molecular biology. The protocol described by Khanuja et al. (1999) is less expensive when compared to the commercial purification kits. |
