Desempenho reprodutivo de fêmeas suínas criadas em clima quente no sul do Piauí / Reproductive performance of sows reared in warm weather in southern Piauí

This study aimed to evaluate and compare the reproductive performance of swine breed Landrace and Large White created in the region the hot weather in the south of Piauí state. Sampling was carried out between pure animals containing such information, the total number of piglets born; number of weaned piglets; date of birth of the piglets; coverage of the array data. These data were submitted to variance analysis, comparing the average standard deviation of characteristics and the coefficient of variation. Landrace of the results showed better reproductive performance than data Large White, the two races are excellent reproductive pattern, so they are considered large arrays in pig farming.(AU)

Caracterização produtiva de espécies de leguminosas forrageiras utilizadas na produção de feno / Productive characterization of species of forage legumes used for hay production

The research was conducted to evaluate the production of fodder legumes used in the production of hay. The experiment was conducted in of Federal University of Piaui in Bom Jesus, Piaui. The design was a randomized blocks with six treatments and three replications. Six forage legumes were used: Macroptillium lathyroides Access 1, Access 2, Access 3, Stylosanthes capitata, Cajanus cajan, Neonotonia wightti. The variables evaluated were: number of plants, green mass of forage production (t ha-1 ) and height. Data were statistically analyzed by Tukey's test at a significance level of 5%. All variables showed differences between the six species of forage legumes (p<0,05). For number of plants per linear meter the S. capitata and N. wightti were higher than 20.00 and 18.00, respectively. The S. capitata and M. lathyroides present better productive characteristics between species.(AU)
