RESUMEN
The objective of this trial was to evaluate the effect of whole rice meal (WRM) inclusion in the concentrate upon body development, carcass traits, and meat quality of lambs. Twenty-four castrated lambs with an average initial body weight of 17.90 ± 2.72 kg were randomly blocked according to two genetic groups (Corriedale and Texel by Corriedale crossbreds). Three isocaloric (11.3 MJ/kg of metabolizable energy) and isonitrogenous (17 % crude protein) diets were offered to the animals for 74 days. Diets consisted of 40 % forage and 60 % concentrate diet, on a dry matter basis, with 0, 15, or 30 % of WRM inclusion into the concentrate. Body growth (after slaughter), carcass, and meat traits were evaluated on each animal. Results obtained indicated that genotype did not affect body growth, carcass, and meat traits except for yellowness. No significant interaction between diet and genotype were detected. Inclusion of up to 30 % WRM did not significantly (P > 0.05) affect body growth, carcass, and meat traits, except for meat color. Meat luminosity progressively increased (36.32 + 0.055X) while redness (15.13 − 0.03X) decreased with the inclusion of WRM in the diet, but still remained within acceptable values. The study indicates that WRM may be included up to 30 % in the concentrate replacing corn without adverse effects upon body development, carcass traits, and meat quality of lambs.

Observou-se a flutuaçäo populacional mensal da Cochliomyia hominivorax e C. macellaria, no Campus da Universidade Federal de Pelotas, no período de fevereiro de 1983 a janeiro de 1986, utilizando-se duas armadilhas orientadas pelo vento (WOT). Durante o período experimental foram capturados 413592 dípteros, dos quais 897 eram C. hominivorax, 8904 eram C. macellaria e 403791 eram outros dípteros, principalmente das famílias Muscidae, Fannidae, Sarcophagidae e outros Calliphoridae. A maior populaçäo de C. hominivorax ocorreu no período de março a maio, sob temperaturas médias superiores a 17, 5§C; a C. macellaria apresentou pique populacional no final da primavera e início de veräo, época em que inicia a ascençäo da temperatura nesta regiäo
